Chapter 1 Getting Started Installing the Java API

Installing the Java API The Java API is part of the SCMS Subscriber Manager Login Event Generator (LEG) distribution file and is located in the SM_API directory.

The Java Subscriber Manager API is packaged in a UNIX tar file. The API is compiled with log4j 1.2. You can extract the Java Subscriber Manager API by using the UNIX tar utility or most Windows compression utilities:

• Subscriber Manager Setup, page 1-4

• Installing on a UNIX Platform, page 1-4

• Installing on a Windows Platform, page 1-4

Subscriber Manager Setup The API connects to the Proprietary Remote Procedure Call (PRPC) server on the Subscriber Manager. To enable the API to operate, the following conditions must be met:

• The Subscriber Manager must be operating, and reachable from the machine that hosts the API.

• The PRPC server must be started.

The PRPC server is a proprietary RPC protocol designed by Cisco. For more information about the PRPC server, see Cisco Service Control Management Suite Subscriber Manager User Guide.

Installing on a UNIX Platform

Note The abbreviations vvv and bb represent the Subscriber Manager Java API version and build number.

To install SCMS Subscriber Manager Java API

Step 1 Extract the SCMS SM LEG distribution file.

Step 2 Locate the Java Subscriber Manager API distribution tar, sm-java-api-dist.tar.

Step 3 Extract the Java Subscriber Manager API distribution tar and obtain sm-java-api-vvv.bb.tar.

#>tar -xvf sm-java-api-dist.tar

Step 4 Extract the Java Subscriber Manager API package tar.

#>tar -xvf sm-java-api-vvv.bb.tar

Installing on a Windows Platform Use a zip extractor (such as WinZip).

Chapter 2 General API Concepts Blocking API and the Nonblocking API

Blocking API and the Nonblocking APIThis section describes the differences between the Blocking API and the Nonblocking API.

• Blocking API, page 2-2

• Nonblocking API, page 2-2

Blocking API In a Blocking API operation, which is the most common, every method returns after its operation is performed.

The Subscriber Manager Blocking Java API provides a wide range of operations. It contains most of the functionality of the Nonblocking API and many functions that the Nonblocking API does not provide. The Blocking API does not support reliability and autoreconnect functionality.

Nonblocking API In a Nonblocking Java API operation, every method returns immediately, even before the completion of its operation. The operation results are either returned to an observer object (listener) or not returned at all.

The Nonblocking API method is preferred when the operation is lengthy and involves I/O. When the operation is performed in a separate thread, the calling program can continue performing other tasks, which improves the overall system performance.

The Subscriber Manager Nonblocking Java API contains a small number of nonblocking operations. The API supports the retrieval of operation results by using a result listener.

The Subscriber Manager Nonblocking Java API supports two modes—reliable and nonreliable. For more information about the reliability modes, see the “Reliability Support” section on page 4-2.


OL-24191-02

Chapter 2 General API Concepts API Initialization

API Initialization To initialize the API, you must complete three tasks:

• Construct the API by using one of its constructors. For details, see the “API Construction” section on page 2-3.

• Perform the API-specific setup operations. For details, see the “Setup Operations” section on page 2-3.

• Connect the API to the Subscriber Manager. For details, see the “Connecting to the Subscriber Manager” section on page 2-4.

API Construction Blocking and Nonblocking APIs have two constructors:

• An Empty constructor

• A Constructor that accepts a Login Event Generator (LEG) name as a parameter.

Constructor that Accepts a LEG Name

Set the LEG name if you intend to turn on the Subscriber Manager LEG failure processing options in the Subscriber Manager. For more information about the LEG software components and SM-LEG failure handling, see the Cisco Service Control Management Suite Subscriber Manager User Guide.

The Subscriber Manager uses the LEG name when recovering from a connection failure. A constant string that identifies the API is appended to the LEG name as follows:

• For blocking API—.B.SM-API.J

• For nonblocking API—.NB.SM-API.J

Blocking API—Example

If the provided LEG name is my-leg.10.1.12.45-version-1.0, the actual LEG name is my-leg.10.1.12.45-version-1.0.B.SM-API.J.

If no name is set, the LEG uses the hostname of the machine as the prefix of the name.

Additional constructors are available for the Nonblocking API. For more information, see the “Nonblocking API Construction” section on page 4-6.

Setup Operations The setup operations differ for the two APIs. Both APIs support setting a disconnect listener, which is described in detail in the “DisconnectListener Interface” section on page 2-9.

• Blocking API Setup, page 2-4

• Nonblocking API Setup, page 2-4


OL-24191-02


Chapter 2 General API Concepts Connecting to the Subscriber Manager

Blocking API Setup

To set up the Blocking API, you must set an operation timeout value. For more information, see Chapter 3, “Blocking API”.

Nonblocking API Setup

To set up the Nonblocking API, you must set a disconnect listener. For more details, see Chapter 4, “Nonblocking API”.

Connecting to the Subscriber Manager To connect to the Subscriber Manager, use one of the following connect methods.

• Use the following method to connect to the Subscriber Manager by using the default remote procedure call (RPC) TCP port (14374):

connect(String host)

• Use the following method to allow the caller to set the TCP port to which the API connects:

connect(String host, int port)

For both methods, the host parameter can be either an IP address or a reachable hostname.

At any time during the API operation, you can check if the API is connected by using the isConnected method.


OL-24191-02

Chapter 2 General API Concepts API Finalization

API FinalizationTo free the resources of both the server and the client, use the disconnect method.

Use a finally statement in your main class, as follows:

public static void main(String [] args) throws Exception { SMNonBlockingApi smnbapi = new SMNonBlockingApi(); try { ... } finally { smnbapi.disconnect(); }}

Subscriber Name FormatMost methods of both APIs require the subscriber name as an input parameter.

A subscriber name can contain up to 64 characters. You can use all printable characters with an ASCII code between 32 and 126 (inclusive), except for 34 ("), 39 ('), and 96 (`).


OL-24191-02

Chapter 2 General API Concepts Network ID Mappings

Network ID MappingsA network ID mapping is a network identifier that the Service Control Engine (SCE) device can map to a specific subscriber record. A typical example of a network ID mapping (or simply, mapping) is an IP address. Currently, the Cisco Service Control solution supports IP address, IP range, private IP address over VPN, private IP range over VPN, and VLAN mappings.

Both Blocking and Nonblocking APIs contain operations that accept mappings as a parameter, such as the following:

• The addSubscriber operation (Blocking API)

• The login method (Blocking or Nonblocking API)

When passing mappings to an API method, the caller is requested to provide two parameters:

• The java.lang.String mapping identifier or array of mapping types

• The short mapping type or array of mapping types

When passing arrays, the mappingTypes array must contain either the same number of elements as the mappings array or a single element. If the mappingTypes array contains a single element, all mappings have the same type, specified by this single element.

The API supports the following subscriber mapping types:

• IP addresses or IP ranges

• Private IP addresses or private IP ranges over VPN

• VLAN tags

For additional information, see the Cisco Service Control Management Suite Subscriber Manager User Guide.

Specifying IP Address Mapping The string format of an IP address is the commonly used decimal notation:

IP-Address=[0-255].[0-255].[0-255].[0-255]

Example:

• 216.109.118.66

Mapping type of an IP address is provided in the com.pcube.management.api.SMApiConstants interface:

– com.pcube.management.api.SMApiConstants.MAPPING_TYPE_IP specifies a single IP mapping that matches the mapping identifier with the same index in the mapping identifier array.

– com.pcube.management.api.SMApiConstants.ALL_IP_MAPPINGS specifies that all the entries in the mapping identifiers array are IP mappings.


OL-24191-02



Chapter 2 General API Concepts Specifying IP Range Mapping

Specifying IP Range Mapping The string format of an IP range is an IP address in decimal notation and a decimal specifying the number of 1s in a bit mask:

IP-Range=[0-255].[0-255].[0-255].[0-255]/[0-32]

Examples:

• 10.1.1.10/32 is an IP range with a complete mask, that is, a regular IP address.

• 10.1.1.0/24 is an IP range with a 24-bit mask, that is, all the addresses ranging between 10.1.1.0 and 10.1.1.255.

Note The mapping type of an IP range is identical to the mapping type of the IP address.

Specifying Private IP Address or Private IP Range over VPN MappingThe string format of an IP address and an IP range are described in the “Specifying IP Address Mapping” section on page 2-6 and in the “Specifying IP Range Mapping” section on page 2-7. When the network ID mapping uses an IP address or range over VPN, the string format includes the VPN name.

Examples:

• 10.1.1.10@VPN1 is an IP address over the VPN named VPN1.

• 10.1.1.0/24@VPN2 is an IP range with a 24-bit mask, that is, all of the addresses in the range from 10.1.1.0 to 10.1.1.255 over the VPN named VPN2.

Note The mapping type of an IP address or IP range over VPN is identical to the mapping type of the IP address.

Specifying VLAN Tag Mapping The string format for VLAN tag mapping is VLAN-tag = 0 to 4095.

The value is a decimal in the specified range.

The com.pcube.management.api.SMApiConstants interface also provides the mapping type:

• com.pcube.management.api.SMApiConstants.MAPPING_TYPE_VPN specifies a single VLAN mapping that matches the mapping identifier with the same index in the mapping identifier array.

• com.pcube.management.api.SMApiConstants.ALL_VPN_MAPPINGS specifies that all the entries in the mapping identifiers array are VLAN mappings.

Note The SMApiConstants.TYPE_VLAN and SMApiConstants.ALL_VLAN_MAPPINGS constants are deprecated. You should use the SMApiConstants.TYPE_VPN and SMApiConstants.ALL_VPN_MAPPINGS constants instead.


OL-24191-02

Chapter 2 General API Concepts Subscriber Domains

Subscriber DomainsThe Cisco Service Control Management Suite Subscriber Manager User Guide defines the domain concept. Briefly, a domain identifies for the Subscriber Manager the SCE devices to which it updates subscriber records.

A domain name is a type of String. During system installation, the network administrator determines the system domain names, which, therefore, vary between installations. The APIs include methods that specify the domain to which a subscriber belongs. The APIs also provide methods that enable queries about system domain names. If an API operation specifies a domain name that does not exist in the Subscriber Manager domain repository, it is considered an error and RpcErrorException is returned.

The Subscriber Manager automatic domain roaming feature enables you to move subscribers between domains by calling the login method for a subscriber with an updated domain parameter as described in the “login” section on page 3-5.

Note Automatic domain roaming is not backward compatible with previous versions of the Subscriber Manager API. Previous versions did not permit changing the domain of the subscriber.

Subscriber PropertiesSeveral operations manipulate subscriber properties. A subscriber property is a key/value pair that affects the way the Cisco SCE analyzes and reacts to network traffic generated by the subscriber.

For information about properties, see the Cisco Service Control Management Suite Subscriber Manager User Guide and the Cisco Service Control Application for Broadband User Guide. The latter provides application-specific information; it lists the subscriber properties that exist in the application running on your system, the allowed value set, and the significance of each property value.

To format subscriber properties for Java API operations, use the String arrays propertyKeys and propertyValues.

Note The arrays must be of the same length, and NULL entries are forbidden. Each key in the keys array has a matching entry in the values array; the value for propertyKeys[j] resides in propertyValues[j]. The mapping type of an IP range is identical to the mapping type of the IP address.

Example:

If the property keys array is {"packageId","monitor"} and the property values array is {"5","1"}, the properties are packageId=5, monitor=1.

Chapter 2 General API Concepts Custom Properties

Custom PropertiesSome operations manipulate custom properties. Custom properties are similar to subscriber properties, but do not affect how the SCE analyzes and manipulates the subscriber traffic. The application management modules use custom properties to store additional information for each subscriber.

To format custom properties, use the String arrays customPropertyKeys and customPropertyValues. This formatting is the same as in the subscriber properties formatting described in the “Subscriber Properties” section on page 2-8.

DisconnectListener InterfaceBoth APIs (Blocking and Nonblocking) enable you to set a disconnect listener. The disconnect listener is an interface with a single method:

public interface DisconnectListener { /** * called when the connection with the server is down. */ public void connectionIsDown();}

Implement this interface to be notified when the API is disconnected from the Subscriber Manager.

To set a disconnect listener, use the setDisconnectListener method.

DisconnectListener Interface ExampleThe following example is a basic implementation of a disconnect listener that prints a message to stdout and exits:

import com.pcube.management.framework.rpc.DisconnectListener;

public class MyDisconnectListener implements DisconnectListener {

public void connectionIsDown(){ System.out.println("Message: connection is down."); System.exit(0); }}

Chapter 2 General API Concepts Exceptions

ExceptionsThe same Java class, com.pcube.management.framework.rpc.RpcErrorException, provides all of the functional errors of the Subscriber Manager Java API. This is contrary to the normal Java usage. This approach was chosen because of the cross-language nature of the Subscriber Manager API. It enables all Subscriber Manager API implementations (Java, C, and C++) to appear similar.

Each exception provides the following information:

• Unique error code (long)

• Informative message (java.lang.String)

• Server-side stack trace (java.lang.String)

The error code can be interpreted by using com.pcube.management.api.SMApiConstants. See Appendix A, “List of Error Codes” for details about error codes and their significance.

Note Several types of errors can occur only if you use the Blocking API. These are operational errors that are related to operation-timeout handling. These errors are described in Chapter 3, “Blocking API.”

Practical TipsWhen implementing the code that integrates the API with your application, consider the following practical tips:

• Connect to the Subscriber Manager once and maintain an open API connection to the Subscriber Manager at all times, using the API many times. Establishing a connection is a timely procedure, which allocates resources on the Subscriber Manager side and the API client side.

• Share the API connection between your threads. It is best to have one connection per LEG. Multiple connections require more resources on the Subscriber Manager side and client side.

• Do not implement synchronization of the calls to the API. The client automatically synchronizes calls to the API.

• Place the API clients (LEGs) in the same order as the Subscriber Manager machine processor number.

• If the LEG application has bursts of login operations, enlarge the internal buffer size accordingly to hold these bursts (Nonblocking API).

• During the integration, set the Subscriber Manager logon_logging_enabled configuration parameter to enable viewing the API operations in the Subscriber Manager log. Setting this parameter enables you to troubleshoot the integration, if any problems arise.

• Use the debug mode for the LEG application that logs the return values of the nonblocking operations.

• Use the automatic reconnect feature to improve the resiliency of the connection to the Subscriber Manager.

• In cluster setups, connect the API by using the virtual IP address of the cluster and not the management IP address of one of the machines.

Blocking API

IntroductionThis chapter introduces the Reply Timeout, a feature unique to the Blocking API.

The chapter also lists all the operations of the Blocking API, and provides code examples.

Note If you need to develop only an automatic integration, skip this chapter and go directly to Chapter 4, “Nonblocking API.”

• ReplyTimeout and OperationTimeout Exception, page 3-3

• Subscriber Manager Blocking API Methods, page 3-4

• Blocking API Code Examples, page 3-43


Chapter 3 Blocking API Multithreading Support

Multithreading SupportThe Blocking API supports an unlimited number of threads calling its methods simultaneously.

Note In a multithreaded scenario for the Blocking API, the order of invocation is not guaranteed.

Example:

Thread-0 calls operation-0 at time-0, and thread-1 calls operation-1 at time-1, where time-1 is later than time-0. In this example, it is possible that operation-1 might be performed before operation-0, as shown in Figure 3-1 (the vertical scale is time):

Figure 3-1 Multithreading Support

The Subscriber Manager (SM) allocates five threads to manage each API instance. Develop a multithreaded application that uses the API with several threads in the order of the five threads. Implementing with more threads might result in longer delays for the calling threads.

Chapter 3 Blocking API ReplyTimeout and OperationTimeout Exception

ReplyTimeout and OperationTimeout ExceptionA blocking operation returns only when the operation result is retrieved from the Subscriber Manager. If a networking malfunction or other error prevents the operation result from being retrieved, the caller waits indefinitely. The Subscriber Manager API provides a means of working around this situation.

The reply timeout feature (the setReplyTimeout method) enables the caller to set a timeout. It will generate com.pcube.management.framework.rpc.OperationTimeoutException when a reply does not return within the timeout period.

Calling the setReplyTimeout method with a long value sets a reply timeout. The reply timeout is interpreted in milliseconds. A zero value indicates that the operation should wait (freeze, stop responding) until a result arrives—or indefinitely, if no result arrives.

There is an alternative way to release a method call that is blocking the caller, who is waiting for a result to arrive. Call the interrupt method of the calling thread; java.lang.InterruptedException will then be returned to the caller.


OL-24191-02

Chapter 3 Blocking API Subscriber Manager Blocking API Methods

Subscriber Manager Blocking API MethodsThis section lists the methods of the Subscriber Manager Blocking API. The description of each method includes its syntax, input parameters, and return values.

The Blocking API is a superset of the Nonblocking API. Except for differences in return values and result handling, identical operations in both APIs have the same functions and syntax structure. All the methods generate java.lang.IllegalStateException when called before the API establishes a connection with the Subscriber Manager.

The Blocking API methods are classified as follows:

• Dynamic IP and property allocation—Use the following methods to integrate the Subscriber Manager API with an authentication, authorization, and accounting (AAA) system. These methods are not designed to add or remove subscribers from the database. Instead, they modify dynamic parameters (such as IP addresses) of the existing subscribers:

– login, page 3-5

– logoutByName, page 3-7

– logoutByNameFromDomain, page 3-10

– logoutByMapping, page 3-11

– loginCable, page 3-13

– logoutCable, page 3-15

• Static or Manual Subscriber configuration—Use the following methods for a GUI:

– addSubscriber, page 3-16

– removeSubscriber, page 3-18

– removeAllSubscribers, page 3-19

– setPropertiesToDefault, page 3-32

– removeCustomProperties, page 3-33

• Use the following methods for simple read-only operations, performed independently in the subscriber awareness mode:

– getNumberOfSubscribers, page 3-20

– getNumberOfSubscribersInDomain, page 3-20

– getSubscriber, page 3-21

– subscriberExists, page 3-23

Chapter 3 Blocking API login

You can mix methods from different categories in a single application. The classification is presented only for clarity.

loginThe following sections provide information about the login operation:

• Syntax, page 3-5

• Description, page 3-5

• Parameters, page 3-5

• RPC Exception Error Codes, page 3-6

• Return Value, page 3-6

• Examples, page 3-6

Syntax

The login syntax is as follows:

public void login(String subscriberName, String[] mappings, short[] mappingTypes, String[] propertyKeys, String[] propertyValues, String domain, boolean isMappingAdditive, int autoLogoutTime)throws InterruptedException, OperationTimeoutException, RpcErrorException

Description

The login method adds or modifies a domain, mappings, and possibly properties of a subscriber that already exists in the Subscriber Manager database. The login method can be called with partial data; for example, it might provide mappings or properties only, and put NULL ++++ in the unchanged fields.

If another subscriber with the same (or conflicting) mappings already exists in the same domain, the conflicting mappings are removed from the other subscriber and assigned to the new subscriber.

If the subscriber does not exist in the Subscriber Manager database, the login method creates it with the data provided.

Parameters

The parameters of the login method are as follows:

• subscriberName—See the description of subscriber name formatting in the “Subscriber Name Format” section on page 2-5.

• mappings—See the description of mappings and mapping types in the “Network ID Mappings” section on page 2-6. If no mappings are specified, and the isMappingAdditive parameter is TRUE, the previous mappings are retained. If no such mappings exist, the operation fails.

• mappingTypes—See the description of mappings and mapping types in the “Network ID Mappings” section on page 2-6.


OL-24191-02

Chapter 3 Blocking API login

• propertyKeys—See the description of property keys in the “Subscriber Properties” section on page 2-8.

• propertyValues—See the description of property values in the “Subscriber Properties” section on page 2-8.

• domain—See the description of subscriber domains in the “Subscriber Domains” section on page 2-8.

If domain is NULL, but the subscriber already has a domain, the existing domain is retained.

If the domain is different from the domain that was previously assigned to the subscriber, the subscriber is removed automatically from the Cisco SCEs of the previous domain and moved to the SCEs of the new domain.

• isMappingAdditive

– TRUE—Adds the mappings provided by this call to the subscriber record.

– FALSE—Overrides the mappings provided by this call with mappings that already exist in the subscriber record.

• autoLogoutTime—Applies only to the mappings provided as arguments to this method.

– Positive value (N)—Automatically logs out the mappings (similar to calling a logout method) after N seconds.

– 0 value—Maintains the current expiration time for the given mappings.

– Negative value—Disables any expiration time set for the given mappings.

RPC Exception Error Codes

The following list presents the error codes the login method might return:

• ERROR_CODE_ILLEGAL_SUBSCRIBER_NAME

• ERROR_CODE_BAD_SUBSCRIBER_MAPPING

• ERROR_CODE_SUBSCRIBER_DOMAIN_ASSOCIATION

• ERROR_CODE_DATABASE_EXCEPTION

• ERROR_CODE_UNKNOWN

This error can be caused by the following parameter settings:

– NULL value for the domain parameter for the subscriber that does not exist or does not have a domain

– Invalid values for the propertyValues parameter

For a description of error codes, see Appendix A, “List of Error Codes”.

Return Value

None.

Examples

Chapter 3 Blocking API loginCable

loginCableThe following sections provide information about the loginCable operation:







Syntax

The loginCable syntax is as follows:

public void loginCable(String CPE, String CM, String IP, int lease, String domain, String[] propertyKeys, String[] propertyValues)throws InterruptedException, OperationTimeoutException, RpcErrorException

Description

The loginCable method is an operation adapted for the cable environment; it calls the cable support module in the Subscriber Manager. This method is designed to log in the customer premise equipment (CPE) and content managers to the Subscriber Manager. To log in a CPE, specify its cable modem (CM) MAC in the CM argument and the CPE MAC in the CPE argument. To log in a cable modem, specify the cable modem MAC address in both CPE and CM arguments. Note that the login of a CPE whose CM does not exist in the Subscriber Manager database is ignored—the CM has to exist in the database, either by import or by a CM login operation. For additional information, see the CPE as Subscriber in Cable Environment chapter of Cisco Service Control Management Suite Subscriber Manager User Guide.

Note The name of the CPE in the Subscriber Manager database is the concatenation of the CPE and CM values with two underscore characters (“_”) between them. The caller must ensure that the lengths of CPE and CM add up to no more than 38 characters.

Parameters

The parameters of the loginCable method are as follows:

• CPE—Unique identifier of the CPE (usually a MAC address)

• CM—Unique identifier of the cable modem (usually a MAC address)

• IP—CPE IP address

• lease—CPE lease time

• domain—See the description of the subscriber domains in the “Subscriber Domains” section on page 2-8. The domain is usually cable modem termination system (CMTS) IP.


OL-24191-02


Chapter 3 Blocking API loginCable

Note Domain aliases must be set on the Subscriber Manager so that the cable modem termination system (CMTS) IP is correctly interpreted as a domain name. For information about configuring aliases, see the Default Domains Configuration section of Cisco SCMS Subscriber Manager User Guide.


If the CPE is provided with partial or no application properties, the values for the missing application properties are copied from the application properties of the cable modem to which this CPE belongs. Each cable modem application property thus serves as a default for the CPE with which it is associated.


Return Value

None.


None.

Examples

To add the IP address 192.168.12.5 to a cable modem called CM1 with two hours lease time:

loginCable( "CM1", "CM1", "192.168.12.5", 7200, // lease time in seconds "subscribers", null, null);

To add the IP address 192.168.12.50 to a CPE called CPE1, which is behind CM1 with lease time of one hour:

loginCable( "CPE1", "CM1", "192.168.12.50", 3600, // lease time in seconds "subscribers", null, null);

Chapter 3 Blocking API addSubscriber

"CM1", "192.168.12.5", "subscribers");

addSubscriberThe following sections provide information about the addSubscriber operation:








Syntax

The addSubscriber syntax is as follows:

public void addSubscriber(String subscriberName, String[] mappings, short[] mappingTypes, String[] propertyKeys, String[] propertyValues, String[] customPropertyKeys, String[] customPropertyValues, String domain)throws InterruptedException, OperationTimeoutException, RpcErrorException

Description

The addSubscriber method creates a new subscriber record according to the method parameters and adds the record to the Subscriber Manager database.

When adding a new subscriber name, if the name already exists in Subscriber Manager database, the first instance of the name is removed before the new one is added. In contrast to login method, which modifies fields and leaves unspecified fields unchanged, the addSubscriber method sets the subscriber exactly as specified by the parameters passed to it.

Note Use the call login method for existing subscribers, instead of the addSubscriber command. You should set dynamic mappings and properties by using the login command. Set static mappings and properties the first time the subscriber is created by using the addSubscriber command.

Note With the addSubscriber command, the autologout feature is always disabled. To enable autologout, use the login command.


OL-24191-02

Chapter 3 Blocking API addSubscriber

Example

Subscriber AB, already set up in the subscriber database, has a single IP mapping (IP1).

If an addSubscriber operation for AB is called with no mappings specified (NULL in both the mappings and mappingTypes fields), AB is left with no mappings.

However, calling the login operation with these NULL-value parameters does not change the subscriber mappings of AB; AB retains its previous IP mapping of IP1.

Parameters

The parameters of the addSubscriber method are as follows:

• subscriberName—See the description in the “Subscriber Name Format” section on page 2-5.

• mappings—See the description in the “Network ID Mappings” section on page 2-6.




• customPropertyKeys—See the description of custom property keys in the “Custom Properties” section on page 2-9.

• customPropertyValues—See the description of custom property values in the “Custom Properties” section on page 2-9.


A NULL value indicates that the subscriber has no domain. If domain is NULL, but the subscriber already has a domain, the existing domain is retained.

Return Value

None.


The following list presents error codes that the addSubscriber method might return:




• ERROR_CODE_SUBSCRIBER_ALREADY_EXISTS


• ERROR_CODE_UNKNOWN

This error code might indicate invalid values that were supplied for the propertyValues parameter.

C H A P T E R 4
Nonblocking API

IntroductionThis chapter introduces features unique to the Nonblocking API. It presents all Nonblocking API methods and provides code examples for each method.


• Reliability Support, page 4-2

• Autoreconnect Support, page 4-3

• Multithreading Support, page 4-3

• ResultHandler Interface, page 4-4

• Nonblocking API Construction, page 4-6

• Nonblocking API Initialization, page 4-8

• Nonblocking API Methods, page 4-9

• Nonblocking API Code Examples, page 4-12


Chapter 4 Nonblocking API Reliability Support

Reliability SupportThe Nonblocking API can work in two different modes—reliable and nonreliable. When the mode is not specified, the default is reliable mode.

• Reliable Mode, page 4-2

• Nonreliable Mode, page 4-2

Reliable ModeIn reliable mode, the API ensures that no requests to the Subscriber Manager are lost. The API maintains an internal storage for all API requests that are sent to the Subscriber Manager. After a reply from the Subscriber Manager is received, the request is considered committed and the API can remove the request from its internal storage. If the connection between the API and the Subscriber Manager fails, the API accumulates all requests in its internal storage until the connection to the Subscriber Manager is established. On reconnection, the API resends all noncommitted and committed requests to the Subscriber Manager, so that no requests are lost.

Note In reliable mode, the order of resending requests is guaranteed. The API resends the requests in the order in which they were called.

Nonreliable ModeIn nonreliable mode, the API does not ensure that requests sent to the Subscriber Manager are executed. In addition, all requests that are sent by the API when the connection to the Subscriber Manager is down are lost unless an external reliability mechanism is implemented.


OL-24191-02

Chapter 4 Nonblocking API Autoreconnect Support

Autoreconnect SupportThe Nonblocking API supports autoreconnection to the Subscriber Manager to address connection failures. When this option is activated, the API can determine when the connection to the Subscriber Manager is lost. When the connection is lost, the API activates a reconnection task that tries to reconnect to the Subscriber Manager until it is successful.

Note The autoreconnect support option can be activated in both reliability modes.

Multithreading SupportThe Nonblocking API supports an unlimited number of threads calling its methods simultaneously.

Note In a multithreaded scenario for the Nonblocking API, the order of invocation is guaranteed. The API performs operations in the same order in which they were called.


OL-24191-02

Chapter 4 Nonblocking API ResultHandler Interface

ResultHandler InterfaceThe Nonblocking API enables you to set a result handler. A result handler is an interface with two methods, handleSuccess and handleError, as represented in the following code:

public interface ResultHandler { /** * handle a successful result */ public void handleSuccess(long handle, Object result);

/** * handle a failure result */ public void handleError(long handle, Object result);}

You should implement this interface if you want to be informed about the success or error results of operations performed through the API.

Note This is the only interface for retrieving results. Results cannot be returned immediately after the API method has returned to the caller.

Note To receive operation results, set the result handler of the API before calling API methods for which you want to receive results. Set the result handler after the API is connected (as in the “ResultHandler Interface Example” section on page 4-4).

Both handleSuccess and handleError methods accept two parameters:

• Handle—Each API operation return-value is a handle of type long. This handle enables correlation between operation calls and their results. When a handle operation is called with a handle of value X, the result will match the operation that returned the same handle value (X) to the caller.

• Result—Actual result of the operation. Some operations may return a result of NULL.

ResultHandler Interface ExampleThe following example is a simple implementation of a result handler that prints a message to stdout (when the result is successful) or to stderr (when the result is a failure). This main method initiates the API and assigns a result handler.

For correct operation of the result handler, follow the code sequence presented in this example.


OL-24191-02

Chapter 4 Nonblocking API ResultHandler Interface Example

Note This example does not demonstrate the use of callback handles.

import com.pcube.management.framework.rpc.ResultHandler;import com.pcube.management.api.SMNonBlockingApi;

public class ResultHandlerExample implements ResultHandler{

public void handleSuccess(long handle, Object result) { System.out.println("success: handle="+handle+", result="+result); }

public void handleError(long handle, Object result) { System.err.println("error: handle="+handle+", result="+result); }

public static void main (String args[]) throws Exception{ if (args.length != 1) { System.err.println("usage: ResultHandlerExample <sm-ip>"); System.exit(1); }

//note the order of operations! SMNonBlockingApi nbapi = new SMNonBlockingApi(); nbapi.connect(args[0]); nbapi.setResultHandler(new ResultHandlerExample()); nbapi.login(...); }}


OL-24191-02

Chapter 4 Nonblocking API Nonblocking API Construction

Nonblocking API ConstructionIn addition to the constructors described in the “API Construction” section on page 2-3, the Nonblocking API provides constructors that enable you to set the reconnect period and the reliability mode.

Nonblocking API SyntaxThe syntax for the additional Nonblocking API constructors is as follows:

public SMNonBlockingApi(long autoReconnectInterval)public SMNonBlockingApi(boolean reliable, long autoReconnectInterval)public SMNonBlockingApi(String legName, long autoReconnectInterval)public SMNonBlockingApi(String legName, boolean reliable, long autoReconnectInterval)

Nonblocking API ArgumentsThe following list describes the constructor arguments for the additional Nonblocking API constructors:

• autoReconnectInterval—Defines the interval (in milliseconds) between attempts to reconnect, as follows:

– If the value is 0 or less, the reconnection task is not activated (no autoreconnect is attempted).

– If the value is greater than 0 and if there is a connection failure, the reconnection task is activated every autoReconnectInterval milliseconds.

Default value is –1 (no autoreconnect is attempted).

Note To enable the autoreconnect support, the connect method of the API must be activated at least once. For more information, see the “Nonblocking API Code Examples” section on page 4-12.

• reliable—An argument that defines whether the API should work in reliable mode, as follows:

– TRUE—The API works in reliable mode.

– FALSE—The API works in nonreliable mode.

Default value is TRUE (the API works in reliable mode).

• legName—The name of the LEG, as described in the “API Construction” section on page 2-3.

Nonblocking API ExamplesThe following example constructs a reliable API with an autoreconnection interval of 10 seconds:

SMNonBlockingAPI nbapi = SMNonBlockingAPI(10000); nbapi.connect(<SM IP address>);


OL-24191-02

Chapter 4 Nonblocking API Nonblocking API Examples

The following example constructs a reliable API without autoreconnection support:

// API construction SMNonBlockingAPI nbapi = SMNonBlockingAPI(); // Connect to the API nbapi.connect(<SM IP address>);

The following example constructs a nonreliable API with autoreconnection support:

// API construction SMNonBlockingAPI nbapi = SMNonBlockingAPI(false,10000); // Initial connection - to enable the reconnect task nbapi.connect(<SM IP address>);


OL-24191-02

Chapter 4 Nonblocking API Nonblocking API Initialization

Nonblocking API InitializationThe Nonblocking API enables you to initialize certain internal properties to customize the API. This initialization is performed by using the API init method.

Note For the settings to take effect, the init method must be called before the connect method.

You can set the following properties:

• Output queue size—The internal buffer size that limits the maximum number of requests that can be accumulated by the API until they are sent to the Subscriber Manager. The default is 1024.

• Operation timeout—The desired timeout (in milliseconds) on a nonresponding proprietary remote procedure call (PRPC) protocol connection. The default is 45 seconds.

Nonblocking API Initialization SyntaxThe syntax for the Nonblocking API init method is as follows:

public void init(Properties properties)

Nonblocking API Initialization ParametersThe Nonblocking API init method has the following parameters:

• properties (java.util.Properties)—Enables setting the following properties described previously:

– To set the output queue size, use prpc.client.output.machinemode.recordnum.

– To set the operation timeout, use prpc.client.operation.timeout.

Nonblocking API Initialization ExampleThe following Nonblocking API code illustrates how to customize properties during initialization. Note that the init method is called before the connect method.

// API construction SMNonBlockingAPI nbapi = SMNonBlockingAPI(10000); // API initialization java.util.Properties p = new java.util.Properties(); p.setProperty("prpc.client.output.machinemode.recordnum", 2048); p.setProperty("prpc.client.operation.timeout", 60000);// 1 minute nbapi.init(p); // initial connect to the API to enable the reconnect task nbapi.connect(<SM API address>);

Chapter 4 Nonblocking API Nonblocking API Methods

Nonblocking API MethodsThis section describes the methods of the Nonblocking API.

All methods return a handle of type long that can be used to correlate operation calls and their results. See the “ResultHandler Interface” section on page 4-4.

The operation results passed to the result handler are similar to the return values described in the same method in the Chapter 3, “Blocking API”, except for the following:

• Basic types are converted to their Java class representation. For example, int is translated to java.lang.Integer.

• Return values of Void are translated to NULL.

Note An error is passed to the result handler only if the matching operation in the Blocking API generates an exception with the same arguments that correspond to the state of the Subscriber Manager database at the time of the call.

All methods will generate java.lang.IllegalStateException if called before a connection with the Subscriber Manager is established.

This section describes the following methods:

• login, page 4-9

• logoutByName, page 4-10

• logoutByNameFromDomain, page 4-10

• logoutByMapping, page 4-10

• loginCable, page 4-10

• logoutCable, page 4-11

loginThis section provides the syntax for the login operation.

Syntax

The login syntax is as follows:

public long login(String subscriberName, String[] mappings, short[] mappingTypes, String[] propertyKeys, String[] propertyValues, String domain, boolean isMappingAdditive, int autoLogoutTime)

The operation functionality is the same as the matching Blocking API operation. See the “login” section on page 3-5 for more information.

Chapter 4 Nonblocking API logoutByName

logoutByNameThis section provides the syntax for the logoutByName operation.

Syntax

The logoutByName syntax is as follows:

public long logoutByName(String subscriberName, String[] mappings, short[] mappingTypes)

The operation functionality is the same as the matching Blocking API operation. See the “logoutByName” section on page 3-7 for more information.

logoutByNameFromDomainThis section provides the syntax for the logoutByNameFromDomain operation.

Syntax

The logoutByNameFromDomain syntax is as follows:

public long logoutByNameFromDomain(String subscriberName, String[] mappings, short[] mappingTypes, String domain)

The operation functionality is the same as the matching Blocking API operation. See the “logoutByNameFromDomain” section on page 3-10 for more information.

logoutByMappingThis section provides the syntax for logoutByMapping operation.

Syntax

The logoutByMapping syntax is as follows:

public long logoutByMapping(String mapping, short mappingType, String domain)

The operation functionality is the same as the matching Blocking API operation. See the “logoutByMapping” section on page 3-11 for more information.

loginCableThis section provides the syntax for the loginCable operation.


OL-24191-02

Chapter 4 Nonblocking API logoutCable

Syntax

The loginCable syntax is as follows:

public long loginCable(String CPE, String CM, String IP, int lease, String domain, String[] propertyKeys, String[] propertyValues)

The operation functionality is the same as the matching Blocking API operation. See the “loginCable” section on page 3-13 for more information.

logoutCableThis section provides the syntax for the logoutCable operation.

Syntax

The logoutCable syntax is as follows:

public long logoutCable(String CPE, String CM, String IP, String domain)

The operation functionality is the same as the matching Blocking API operation. See the “logoutCable” section on page 3-15 for more information.

Chapter 4 Nonblocking API Nonblocking API Code Examples

Nonblocking API Code ExamplesThis section presents example code for logging in and logging out subscribers.

Login and LogoutThe following example logs in a predefined number of subscribers to the Subscriber Manager and then logs them out. Note the implementation of a disconnect listener and a result handler.

package nonblocking;

import com.pcube.management.framework.rpc.DisconnectListener;import com.pcube.management.framework.rpc.ResultHandler;import com.pcube.management.api.SMNonBlockingApi;import com.pcube.management.api.SMApiConstants;

class LoginLogoutDisconnectListener implements DisconnectListener { public void connectionIsDown() { System.err.println("disconnect listener:: connection is down"); }}

class LoginLogoutResultHandler implements ResultHandler { int count = 0; //prints a success result every 100 results public synchronized void handleSuccess(long handle, Object result) { Object tmp = null; if (++count%100 == 0) { tmp = result instanceof Object[] ? ((Object[])result)[0] : result; System.out.println("\tresult "+count+":\t"+tmp); } }

//prints every error that occurs public synchronized void handleError(long handle, Object result) { System.err.println("\terror: "+count+":\t"+ result); ++count; } //waits for result number 'last result' to arrive public synchronized void waitForLastResult(int lastResult) { while (count<lastResult) { try { wait(100); } catch (InterruptedException ie) { ie.printStackTrace(); } } }}

public class LoginLogout { public static void main (String args[]) throws Exception{ //check arguments checkArguments(args); int numSubscribersToLogin = Integer.parseInt(args[2]);

//instantiation SMNonBlockingApi nbapi = new SMNonBlockingApi();

Chapter 4 Nonblocking API Login and Logout

try { //initation nbapi.setDisconnectListener( new LoginLogoutDisconnectListener()); nbapi.connect(args[0]); LoginLogoutResultHandler resultHandler = new LoginLogoutResultHandler(); nbapi.setResultHandler(resultHandler); //login System.out.println("login of "+numSubscribersToLogin +" subscribers"); for (int i=0; i<numSubscribersToLogin; i++) { nbapi.login("subscriber"+i, //subscriber name getMappings(i), //a single ip mapping new short[]{ SMApiConstants.MAPPING_TYPE_IP }, null, //no properties null, args[1], //domain false, //mappings are not additive -1); //disable autologout } resultHandler.waitForLastResult(numSubscribersToLogin); //logout System.out.println("logout of "+numSubscribersToLogin +" subscribers"); for (int i=0; i<numSubscribersToLogin; i++) { nbapi.logoutByMapping(getMappings(i)[0], SMApiConstants.MAPPING_TYPE_IP, args[1]); } resultHandler.waitForLastResult(numSubscribersToLogin*2); } finally { nbapi.disconnect(); } } static void checkArguments(String[] args) throws Exception{ if (args.length != 3) { System.err.println("usage: java LoginLogout "+ "<SM-address> <domain> <num-susbcribers>"); System.exit(1); } } //'automatic' mapping generator private static String[] getMappings(int i) { return new String[]{ "10." +((int)i/65536)%256 + "." + ((int)(i/256))%256 + "." + (i%256)}; }}
