The resources to invest in technology are driven by business capabilities. To capitalize on this marketplace, one needs to understand that e-business is about business and that companies are evolving and maturing in their ability to leverage Web technologies enabling new business functionality. This chart the ways of e-business implementation. What many companies had gone through in the past several years was trying to establish a basic Web presence in order to enhance the efficiency and cost effectiveness of how they deliver their existing services, both externally to their customers as well as internally to employees within the enterprise. As those capabilities matured, we started to see opportunities to develop new channels and new products and services in Wave 2. Now many companies are into Wave 3 and really reinventing their marketplaces, reinventing their enterprises, leveraging Web technologies to deliver new business capabilities.

Notes: e-business Transition Path

This is a graphic representation of the evolutionary stages of e-business; most companies started out with a basic presence on the Web, static publishing, needed to mature to a level to have some two way exchange of information that's now matured to a point where they want to be able to have the ability to conduct secure transactions over the Web. In the interact stage or integrated stage they want to be able to have these transactions that are actually integrated to backend applications and really leverage the legacy applications and data that many companies have heavily invested in, but they want to make them visible to customers and business partners through the Web.

The evolution of e-business can be summarized as follows: companies started out with a basic presence on the Web, static publishing, but soon felt the need to establish a level on which they could have some two way exchange of information that's now matured to a point where they want to be able to have the ability to conduct secure transactions over the Web. When setting up an environment that allowed interaction or integration, they wanted to be able to have the transactions that are actually integrated to backend applications and really leverage the legacy applications and data that many of our customers have heavily invested in, and wanted to make them visible to their customers and business partners through the Web.Each of these stages has corresponding infrastructure requirements. This is a highly simplified version that suggests that as a customer moves through various stages of Web functionality or business capability that's enabled by the Internet or Intranet, there's a corresponding complexity of the technology environment.

Notes: Maturing Infrastructure



e-business Challenges

Growing Demands:High demand for services, low tolerance for failure

Value of e-business infrastructure correlated to availability, responsiveness and performance

Customer relationship based on services rather than products

Unbalanced IT Investment:Infrastructure requirements driven by business objectives

Web development funding outpaces infrastructure investment

E2E availability / business continuity driven by business process integration

Increasing Complexity:Significant investments in skills and processes to deliver on service levels

IT outsourcing results in complex chain of service delivery



Notes: e-business Challenges

A significant transformation is required in the area of technical strategy, since the environment that our customers we work with is changing very dynamically and several are struggling to keep pace. There are significant increase in demands for quality of service: one's competition is only a click away. The Web user has very stringent demands for availability and performance and the Web has to always be on. If a company's application may be there but the underlying support, whether it's a call center or some other contact center type of support is only available during limited hours, this will not be sufficient: a company needs to be there when its customer or business partner needs it to be there.

Another issue that there has been an imbalance in investment. A lot of these e-business infrastructure investments are driven by line of business executives. There's a major focus on the business functionality, on the applications and data. Often not a corresponding and appropriate level of investment to make sure the infrastructure and the infrastructure management capabilities are in place to achieve the appropriate return on that investment. The management of service levels in this environment is a huge challenge for many customers. There are many companies who are still very immature in their ability to define and manage a measurable level of service to achieve the expectations of their line of business customer who are trying to achieve the service delivery requirements of external users.

Another major issue in this environment is a very complex service delivery chain. Many years ago most of the end-to-end infrastructure structure was under the control of the IT organization within an enterprise. This is clearly no longer the case. First of all nobody can control the entire Internet. Secondly, even when there are pieces of the infrastructure that is being managed by the enterprise IT organization, many elements of that are outsourced to service providers. Many applications are delivered by one company doing the web hosting, while others may provide the applications running behind it, thus delivering a complex service delivery chain which has significant implications for the underlying infrastructure management processes that are necessary to achieve a high level of service in this environment.

What Does WebSphere Do?



Fundamentally WebSphere does three things:WebSphere provides the infrastructure to deliver a compelling end-user experience. This include personalization of content, streamlined access to that content, along with access to applications and collaborative services, supported across the industry's pervasive devices. This is really about building customer loyalty.WebSphere includes the infrastructure to let you choreograph and orchestrate the events, applications, and people that participate in your core business processes, letting you manage those business processes efficiently and change at will. This is really about agility, and time to market.WebSphere provides the underlying services for the above through the foundational enabling technologies supplied by our application server and message-oriented middleware, message brokering, and so on. The base infrastructure is like a system of highways and roads, providing a reliable means for transport. Applications that customers buy and build are like the cars that run on those roads. And tools, a key differentiator for IBM, are like the manufacturing lines that build the cars.

Taken as a whole, WebSphere delivers excellent return on investment and low total cost of ownership because it addresses the compelling needs of business executives while providing the productivity and scale demanded by IT. WebSphere represents a complete, well integrated solution set for e-business.

Notes: WebSphere Application Server V4 for iSeriesThis foil is a high level summary of the two WebSphere Application Server V4 editions for iSeries

Advanced Single Server Edition Version 4.0Advanced Edition Version 4.0

Note that both versions are additional cost - in comparison to WebSphere Application Server Standard Edition 3.5 which is a no charge program under OS/400. (WAS editions and their service support dates are shown in a following foil. The planned, but not yet available WebSphere Application Server Version 5 is discussed in a later foil.

Full J2EE 1.2 (Java 2 Platform, Enterprise Edition) compliance support is the primary set of functions that distinguish WAS Version 4.0 from WAS Version 3.5 functions. J2EE 1.2 support a robust suite of server-side middleware for application development and run time management. WAS 4.0 is fully J2EE 1.2 compliant.

J2EE defines a standard that applies to all aspects of architecting and developing and running multi-tier applications. It defines a standard architecture composed of an application model, a platform for hosting applications, a Compatibility Test Suite (CTS) and a reference implementation. The primary concern of J2EE is the platform specification. This describes the runtime environment for a J2EE application. This environment includes application components, containers, resource manager drivers, and databases.

The elements of this environment communicate with a standard set of services that are also specified in J2EE. J2EE makes all Java enterprise APIs an functionality available and accessible in an integrated manner. This integration aids in simplifying complex problems in the development, deployment, and management of multi-tier server-centric enterprise solutions.

The J2EE standard includes a complete set of specifications and compliance tests that ensure your applications are portable, especially in the areas of Java servlets, Java Server Pages (integrated HTML Java statements), and the latest levels of XML (eXtendable Markup Language) to manage data interchange, and Java Transaction API (JTA) support. Inherent in all this support is database transaction integrity (commit or rollback) across multiple systems and database implementation.

The iSeries WebSphere Application Server 4.0 has passed the J2EE 1.2 Compliance Test Suite (CTS), which is what verifies that an application server provides the required J2EE 1.2 capabilities.



Notes: WebSphere Application Server V4 for iSeries -2July 29 2002, Sun Microsystems announced a Java Verification Program for testing enterprise applications to ensure their compatibility with all application server software products that comply with the J2EE (Java 2 EnterpriseEdition) standard. The suite of tests and reference material allows ISVs (independent software vendors) and corporate software developers to make sure applications they design work with any J2EE application server from any vendor - they do not contain any operating system or specific application server requirement. The test kit, called Java Application Verification Kit for the Enterprises is used to ensure any product stating J2EE support can also verify any unique extensions all conform to the J2EE specifications.

There are also plans for a similar test suite for verifying conformance to Java2 Micro Edition (J2ME), which is defined for use with small computing devices, such as cell phones and personal data assistant (PDA) devices.

For more details refer to http://java.sun.com/j2ee/verified/index.html.

J2EE includes improved ways to package your application, and access data. For example, previous WAS versions support the IBM Toolbox for Java JDBC driver. However, this JDBC driver could not be used with JTA support . JTA had to be enabled for a JDBC driver when using entity enterprise beans that used multiple JDBC connections within a transaction. WAS 4.0 directly supports JTA with the Toolbox JDBC driver.

WAS 4.0 also supports Web services, which is a new set of standards that allow application components to be made available as reusable sets of services. These services are self-contained entities that may be described, published, located and invoked over the Internet. Later in this presentation there are foils on Web Services.

Note that V5R2 level of iSeries Access for the Web- Host Publisher functions require WAS 4.0.

WAS 4.0 supports the following Web servers:IBM HTTP Server Powered by Apache (recommended)IBM HTTP Server (original)Domino Webserver 5.0.3 or laterIntegrated with WAS 4.0 internal HTTP server (basic functions, intended for testing purposes)

A compete treatment of supported WebSphere Application Server 4.0 functions is beyond the scope of this presentation. The following tables show various groupings of WAS V4.0 functions in the two editions available and the support time period for WAS 3.5 and WAS 4.0.

Notes: WAS for iSeries: Edition Support Information

This foils shows two sets of information

Sub-capacity pricing for specific WebSphere products On April 29, 2002, iSeries announced "sub-capacity pricing" for OS/400 releases V4R4 or later running on IBM eServer iSeries and AS/400 hardware capable of logical partitioning (LPAR) for selected WebSphere products as shown on this foil.. This will allow customers to pay for software based on the number of processors in each logical partition where the program is running rather than the total number of processors of the entire system.

The new terms are included in copies of these products manufactured as of July 2002. However, the new terms do not prevent customers who do not wish to take advantage of a subcapacity license from licensing the product for the full capacity of the machine.

The following are some details. For additional details on subcapacity pricing, refer to web site:http:/www.ibm.com/servers/eserver/iseries/software/

The charges and licenses are based upon whole (100 percent) processors per partition. With subcapacity pricing, the number of processors which need to be licensed is the aggregation of all processors, including partial shares of a processor, across all partitions of a single machine (where the program is defined or used), rounded up to the nearest whole number. On an iSeries machine, logical partitions are sized in processor units with one processor unit equal to the size of one dedicated processor. For example, if a 4-way iSeries machine has WebSphere Advanced Application Server running in two (2) partitions sized at 0.6 processor units and 0.7 processor units respectively, the total number of processor units is 1.3. This customer would require authorizations to use the product on two (2) processors as the product is priced and licensed based on the whole number of processors.

For the current level of these products, customers are responsible for compliance with their license entitlement at the time that they configure the size of their logical partition(s) that will contain products that have subcapacity licensing. Customers can configure partitions up to the number of processor licenses that they have acquired. In future releases of these products, IBM plans to have the license manager monitor the number of processors that these products are using. Customers will receive warning messages if they exceed the usage defined in the license manager. If a customer gets one of these warnings, the customer can either acquire additional licenses or decrease the use of the product to become compliant with their current license entitlement.

WebSphere Application Server V5 for iSeries

WebSphere Express V5*Low cost alternative for WAS Standard Edition customers Supports iSeries and Intel (Windows 2000 & Linux)For departments or small/medium business, requiring support for Servlets & JSPsWebSphere Express is not J2EE certified and does not include advanced function in WAS Advanced

No EJB support and no multi-server capabilities for most robust, reliable web sites

WebSphere Advanced Single Server Edition V5*Mission Critical Features: J2EE Certified (JDK 1.3), Web Services, (SOAP, UDDI, WSDL), New single server configuration option, Improved Manageability, Increased PerformanceFor standalone department or small/medium business

WebSphere Advanced Edition V5*Supports Single Server Edition functions Plus multi-server capabilities such as clustering, enhanced administration, distributed security, workload management, and much more

*Version 5 is discussed in the press. However, since this version has not been formally announced for iSeries as of July 2002, the information presented herein represents IBM's plans which can be changed without notice.



WebSphere Express consists of development tools and an application server. The development tools are available with several of the WebSphere Studio tool configurations. The application server is a subset of the WebSphere Application Server offering. WebSphere Express for iSeries consists of the following:

An application server run time environment to be integrated with iSeries. The Express application server is functionally:Equivalent to the application server provided with WebSphere Express for Windows and NT.A subset of the application server shipped with the WAS for iSeries product.

A Web based administration console for administering application servers and their applications. The current web based HTTP server administrative interface will be enhanced to support management of local web and application servers. Wizards will allow administers to quickly create, delete, list and change HTTP and application servers. Applications can easily be deployed, started, stopped and configured.Development tools are included with WebSphere Studio. WebSphere Studio is a set of IBM development tools offerings. There are several different tool configurations, each targeting different levels of application development and platform specifics. For iSeries application development, the WebSphere Development Studio (WDS) tooling is the most popular tool offering. WDS is being enhanced 4Q/2002 to support the WebSphere application server run time.

Tomcat is a no-cost web application server which is a plug-in to our HTTP server Powered By Apache. Tomcat is a low-cost way for customers to get experience with web application servers. Note that WebSphere Express is a response to requests to have a low cost WAS product similar to the WAS 3.5 Standard Edition , that can be used as an alternative to Tomcat.

For robust deployable web sites, WebSphere Application Server Single Server Edition is the solution. Single Server is ideal for a small department in a large company or a small/medium company.

WebSphere Advanced Edition V5 includes all the function in Single Server plus many additional functions delivering advanced function in the multi-server capabilities.

WAS and ASF Jakarta Tomcat Positioning



Notes: WAS and ASF Jakarta Tomcat Positioning

The IBM HTTP Server, powered by Apache, has been enhanced to support the standard Java servlet and Java Server Pages (JSP) engine based on the technology from the Apache Software Foundation's Jakarta Tomcat product . The 3.x releases of Tomcat, as shipped with OS/400 today, implements the Servlet 2.s and JSP 1.1 specifications. Tomcat provides a basic web application server for iSeries customer and is available for V4R5 and later of OS/400 at no cost. There are no plans for IBM to officially support V4 of ASF Jakarta Tomcat in the future. However, an open source version for iSeries will be provided to the open-source community to ensure routes to business continuity for iSeries customers.

ASF Jakarta Tomcat is available as a way for small iSeries customers to get started with Java server-side components and web application serving; however if the requirement is to deploy e-business solutions that are J2EE compliant, support web services and provide the most function and deliver the highest levels of reliability, scalability and security, they should select the WebSphere Application Server.If an IBM or ISV application requires WebSphere Application Server as the base web application server, ASF Jakarta Tomcat should not be considered as an alternative, low-cost solution. Examples of IBM solutions which require WebSphere Application Server as the base web application server include WebSphere Commerce Suite, WebSphere Payment Manager, WebSphere Host Publisher and WebFacing.

Notes: Web Services Overview

Web services is a relatively new technology that is poised to connect enterprises to their business partners and customers, as well as build bridges between disparate IT systems, all without traditional software and extensive development effort.

The Universal Description, Discovery and Integration (UDDI) project is a project that creates a platform-independent, open framework for describing services, discovering businesses, and integrating business services using the Internet, as well as an operational registry that is available today. UDDI is the cross-industry effort driven by all major platform and software providers, as well as marketplace operators and e-business leaders. The UDDI project takes advantage of WorldWide Web Consortium (W3C) and Internet Engineering Task Force (IETF) standards such as Extensible Markup Language (XML), and HTTP and Domain Name System (DNS) protocols.Businesses of all sizes can benefit from UDDI, because the specifications comprehensively addresses problems that limit the growth and synergies of B2B commerce and Web services. UDDI is not industry-specific. Any industry, worldwide, offering products and services can benefit from this open initiative.

Web Services Description Language (WSDL) describes the answers to the following questions:What are the services offered in your online business?How can you invoke your business services?What information do your business services need from the user when he or she invokes your service?How will the user provide the required information?In which format will the services send information back to the user?

Simple Object Access Protocol (SOAP) is a lightweight protocol for exchange of information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts:

An envelope that defines a framework for describing what is in a message and how to process it.A set of encoding rules for expressing instances of application-defined datatypes.A convention for representing remote procedure calls and responses.

SOAP can potentially be used in combination with a variety of other protocols.

WebSphere Commerce Entry Edition (WCEE)

Single online store running on a single iSeries processor

Requires minimum of 460 CPW (270-2431 (465 CPW), 820-2435 (600 CPW))

All software capabilities of WebSphere Commerce Professional Edition except Sametime component

Approximately 1/4 price of WSCPE



Notes: WebSphere Commerce Entry Edition (WCEE)

During July 2002 IBM launched another initiative designed to make the iSeries a less expensive choice for smaller businesses. The new Entry Edition of WebSphere Commerce provides most of the functionality of Commerce Professional Edition, at a quarter of the price.

Not to be confused with the WebSphere Application Server (WAS) entry edition, WAS Express, which is expected in the fourth quarter, Commerce Entry Edition includes most of the capabilities needed to produce a full-featured e-commerce site, including WAS, which is bundled in the software. The Commerce Entry Edition license is limited to a single online store running on a single iSeries processor.

Professional edition, approximately $80K (US), is more than most people need, and it's more than they're willing to pay," says Jeff Jones, IBM's manager for WebSphere Commerce for iSeries. "The assumption was that people just starting out don't really need a multiprocessor product. They can use it on single processors, and the price has been reduced to get their foot in the door."

Commerce Entry Edition costs approximately $20K (US).

Bleddyn Williams, chief e-business architect at Morpheus eBusiness Solutions, asked IBM about offering an entry edition when he was getting ready to retool the online store of a client, Majestic Wines. The site had been developed with WebSphere Commerce V4.1, and although it worked fine and even garnered awards, Williams wanted to add some functionality available in the more expensive V5.4 on a new site running on a model 270 uni-processor machine.

"That single-processor 270-2432 is the reason why I asked Toronto for an entry version," Williams says. "In the Pro version of Commerce, there are a lot of things that the initial store wouldn't need when first getting started. The [Professional Edition] product is aimed at big, big business. Things like Sametime may be great in the future for your e-commerce store depending on your size, but you need to capture market share. And even for companies like Majestic, they are no use. Most people also wouldn't need multiple stores, so the license thing is fine."

The only feature of Professional Edition that Entry Edition doesn't include is the Sametime instant messaging capability used for live help.

The only real limitation in performance is that a single processor can process fewer transactions per hour than multiple processors, Jones says. Although the number of transactions supported varies according to processor size and configuration, a single iSeries processor can handle thousands of transactions per hour, Jones says, which gives resellers another chance to snatch business away from Windows servers.



Although Commerce Entry Edition runs on Windows as well as iSeries, a single Wintel processor doesn't have the horsepower of a single iSeries processor, Jones says. And combined with the 50 percent discounts of the GreenStreak promotion on a single-processor 270 or 820, a small shop could start an e-commerce site on the iSeries for about half of what it would have cost before, making the solution for attractive to erstwhile Windows users.

Commerce requires a minimum of 460 CPW to run. You can use IBM's Workload Estimator to get an idea of what size server you'll need: http://www-912.ibm.com/servlet/EstimatorServlet . For more information on Entry Edition, see IBM announcement letter 202-042.

Making some e-business applications really fast



Notes: Making some e-business applications really fast

We add to this e-business presentation some information on the various web page caching algorithms available on iSeries that can speed up response time.

After summarizing caching techniques available before V5R1, we specifically focus on the new with V5R2 available Fast Response Accelerator Cache (FRCA) support.

Notes: Local Cache - Independent of FRCA

This foil summarizes the fixed and dynamic cache support available on iSeries through V5R1 - still very useful with V5R2.

In V5R1 the Triggered Cache Manager was made available. These and FRCA cache mechanisms are discussed in more detail in Performance presentation.



FRCA: Features

Two new components that work togetherFast Response Cache Accelerator (FRCA)

Provides system API set and framework for socket applicationsAccelerates file serving performance for the HTTP serverThe one V5R2 example is the HTTP Server (powered by Apache)

Network File Cache (NFC)Provides iSeries SLIC level cache

Configurable by new FRCA directives in Apache server configurationCan be enabled for specific "listen port"

Local cache: Specify file name (with wild cards) for "static" content cachingWhen content is updated NFC automatically uses new file

Reverse proxy cache: Specify URI for "dynamic" or remote content cachingTimer used to determine when cached items are stale



Responding to the growing need for improved speed and performance of Web servers, IBM research has defined the Adaptive Fast Path Architecture (AFPA). AFPA has been implemented on several server platforms including Windows NT and Windows 2000, OS/390, AIX and most recently Linux. The external product name is most commonly known as Fast Response Cache Accelerator (FRCA).

AFPA is a software architecture that dramatically improves the capacity of Web and other TCP servers. The architecture defines interfaces that allow these generic mechanisms to be exploited to accelerate a variety of application protocols, with the focus on HTTP. The architecture is general purpose and applicable to many TCP servers, including FTP, NFS, DNS and Domino.

For OS/400 V5R2, this architecture is implemented as the FRCA feature with the HTTP Server (powered by Apache).

Since, the iSeries TCP stack runs in a SLIC router task and not a software interrupt, the FRCA code also executes in a SLIC router task context. The SLIC based implementation eliminates the overhead of switching from a SLIC router task to a user-level server thread. FRCA provides system APIs that can be used by system applications, at this time, the HTTP Server (powered by Apache). HTTP Server (powered by Apache) uses this APIs to work with SLIC FRCA code and Network File Cache (NFC) for serving contents.

The AFPA architecture includes a network file cache that serves non-secure static content. This architecture is implemented as the Network File Cache (NFC) with FRCA feature for the HTTP Server (powered by Apache). NFC provides the capability to efficiency store and retrieve cached entries of file data and user data.

FRCA directives are provided to the HTTP Server (powered by Apache) that enables your HTTP server to use FRCA cache. FRCA cache can be enabled for each listen port in the server configuration. This allows us to make choice if you use FRCA cache or not for each Listen on a specific <IP address:port>.

Static content can be cached by specifying file name using certain directives. The loading to the cache occurs during starting up of the HTTP server or the first access to that file, and this depends on which directive is used. You can use an asterisk (*) as a wild card character on the file names. Then you can specify the directory name with the asterisk to make FRCA cache for some temporary files like the ones created by TCM.

Dynamic content such as result of CGI or servlet can be cached by specifying URI of the request and cache life time. This is a reverse proxy cache support that allows you to access an HTTP server either on this same iSeries or anywhere on your intranet or Internet to get new data every "n" units of time.

This foil shows the scenario when the file is found in the FRCA cache. That is, the cache hit scenario.

The steps from request through response are as follows.1 An HTTP request received by TCP and passed to the FRCA.2 The FRCA intercepts the HTTP request and passes it to the SLIC HTTP Server code. 3 The SLIC HTTP Server code parses the HTTP request and uses the URL as a search key into the HTTP logical cache (Hash table).4 When the HTTP logical cache lookup is successful, Network File Cache (NFC) is called to locate the file data using the NFC handle found in the hash table. 5 NFC finds the file using the handle, and returns it to the SLIC HTTP Server code.6 The SLIC HTTP Server code builds the HTTP response header and links the file data to it, and sends it as a response through TCP/IP.

The above path can result in a sizable performance (of a single transaction) and capacity (allowing more transactions per unit time) improvement due to:

Never having to go above the Machine Interface (MI). This results in:No task switches to the threaded job model above the MICould (depending on a variety of things) save 2 copies of the data. FRCA will not copy the data it finds in the NFC. FRCA will directly send the data to the TCP/IP stack in the iSeries SLIC.

Code path length should be shorter which will result in CPU utilization for cache hits to be lower.

Notes: FRCA: Local Cache Hit Scenario



FRCA Considerations

No SSL/TLS supported for the FRCA enabled sessions/ports

No authentication protection for the file in FRCA (NFC)Contents should be for public access under FRCA

No NLS code page conversion performed

IFS files are read in binary and loaded into the NFC cache as is



Notes: FRCA Considerations

FRCA does not support SSL and/or TLS, therefore you cannot enable FRCA cache for the sessions or ports with SSL/TLS. The reason is because SSL and TLS works above MI while FRCA works below MI.

Since you can enable FRCA cache for each listen port, the ports with SSL and without SSL can coexist in the same server and can access them as a different server using virtual host.

Once the file loaded into the NFC, it can be accessed by any users accessing files in the same server instance. Entries in the NFC are keyed by instance so there is some protection between server instances that happen to be serving the same file (the file will actually be placed in the NFC twice in this case). This is because authorization check is also performed above MI.

When a request for the file that is already in the NFC comes, the file will be served without authorization check since FRCA has no way to do it. For this reason, you should enable the FRCA cache only for the contents that can be public.

Similarly, since the code conversion is also performed above MI, code conversion is not supported. IFS files are read in binary and loaded into the cache as is. Generally, you do not need any code conversion for the files in the IFS to be served by the HTTP server. So this limitation should have no impacts.

If you have the same contents in a different language, they contents must be in different files, or if they have the same name, they must be in different directories. Therefore, each file can be cached and served independently.

Note on Transport Layer Security (TLS) protocol: The TLS protocol provides communications privacy over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. the TLS protocol itself are based on the SSL 3.0 Protocol Specification as published by Netscape. The differences between this protocol and SSL 3.0 are not dramatic, but they are significant enough that TLS 1.0 and SSL 3.0 do not interoperate (although TLS 1.0 does incorporate a mechanism by which a TLSimplementation can back down to SSL 3.0). See RFC 2246 for details. RFC 2246 can be found in several sources, one of which is V5R2 Information Center at Security -> Secure Sockets Layer -> SSL concepts.

Notes: Network File Cache Configuration

FRCA requires usage of the new for V5R2 Network File Cache. This foil explains Network File Cache is set up.

IPLThe initialization of the Network File Cache component will occur during the IPL when the other file servers are initialized.

Configuration values in Change TCP/IP Attributes (CHGTCPA) - new with V5R2Enablement

Specifies whether the Network File Cache (NFC) function will be enabled on this system. The default value is *YES.When you specify *CLEAR for this parameter, it immediately clears the entire Network File Cache. After the cache is cleared, the previous Network File Cache values will be retained.

Cached file time-outSpecifies the maximum amount of time, in seconds, that a file can be cached in the Network File Cache. This ensures that a file is refreshed at a regular interval. A value of *NOMAX is available.A cache time can be specified when NFC is not enabled.

Cache sizeSpecifies the maximum amount of storage that may be used by the NFC for the entire system. This is the accumulative storage used by all TCP servers for loading files. A cache size can be specified when NFC is not enabled.



FRCA Configuration: Enablement

FRCA cache can be enabled for each separate ListenListen [IP address:]port-number <optional parameter>

The <optional parameter> is "FRCA" and is used to enable FRCA cacheExamples:Listen 10.5.5.5:80 FRCA

Listen 10.5.5.5:443

Two directives to turn on/off other FRCA directives To give you the ability to turn off FRCA without having to comment out numerous local cache or reverse proxy cache directives.

Local cache:FRCAEnableFileCache On/Off

Enables/disables FRCA local cache for this server instance (server context)

Reverse proxy cache:FRCAEnableProxy On/OffEnables/disables FRCA reverse proxy cache for this server instance (server context) and VirtualHost context



Notes: FRCA Configuration: Enablement -1This foils shows the primary HTTP server directives to put FRCA into effect for a specific server. There are additional directives that control additional "behavior" of FRCA, such as size of the local cache, FRCA cache activity logging, and what and when files are to be cached. These additional directives are not detailed in this presentation. For more details, see Information Center -> e-business and Web servers.

Directive to enable configuration and use of a specific IPaddr:port for FRCA

You can use this option on the Listen directive to enable or disable using of the FRCA caching support for this IP address and port. This directive can be used only in server configuration context.Example:

Listen 10.5.5.5:80 FRCAListen 10.5.5.5:443

This example enables use of FRCA cache for this server instance on port 80. Any request that comes in for port 443 (assume that port 443 is SSL/TLS traffic) is not cached by FRCA.

The directive shown turns on or off the use of local cache and applies to each server instance.

You can optionally specify a reverse proxy cache which essentially tells the HTTP server that every "n second" when a specific URI (Universal Relocator Indicator (consider this a "prefix" within a URL) is received go to another server instance to find the requested page. The "other instance" responds with the page, which is then kept in the local Network File Cache on the local system. When "n seconds" have expired, get the same page "again" from the second server. This second server would be the one responsible for updating the web page (file). The next foils give some additional information.

Notes: FRCA Configuration: Enablement -2

Two directives to turn on/off other FRCA directives To give you the ability to turn off FRCA without having to comment out numerous local cache or reverse proxy cache directives you can use these two 'switch' like directives.

The local cache 'switch' FRCAEnableFileCache On/Off works only within the Server Context and will enable or disable FRCA local caching for the entire server instance. That is, If FRCAEnableFileCache is off, all other FRCA file cache related directives in the configuration file are ignored.

The default is off, so if you will be using FRCA local cache you should explicitly turn this feature on with the directive FRCAEnableFileCache on

The reverse proxy cache 'switch' FRCAEnableProxy On/Off works within the Server Context and any VirtualHost contexts and will enable or disable FRCA reverse proxy caching. That is, If FRCAEnableProxy is off, all other FRCA reverse proxy cache related directives in the configuration file are ignored (within the context - see the notes below for an explanation of this).

The default is off, so if you will be using FRCA reverse proxy cache you should explicitly turn this feature on with the directive FRCAEnableProxy on

Example 1: FRCAEnableProxy onThis example enables use of FRCA proxy for the server configuration section for the server instance.

Example 2: <virtualhost 1.2.3.4>FRCAEnableProxy on </virtualhost>This example enables use of FRCA proxy for the virtual host 1.2.3.4 section for the server instance.

Notes:Virtual hosts do not inherit the FRCAEnableProxy setting from the server configuration. If FRCAEnableProxy is set to off in the server configuration section, only FRCA directives in server configuration section are ignored. If FRCAEnableProxy is set to off in a virtual host section, only FRCA directives in that virtual host section are ignored.

The next foil give a summary example of a FRCA HTTP server set of directives configuration and a web request processing scenario.

Notes: FRCA Configuration Example

(1) Listen 10.5.92.14:8080 FRCASpecifying Listen directive with the parameter "FRCA" enables FRCA cache for this port. (1) FRCAEnableFileCache OnThis directive enables FRCA cache for this server instance ITSO99. The other directives for specific settings of FRCA all depends on this directive is on or off. (2) FRCACacheLocalFileStartUp /ITSO/itso99/ITSOco/Downloads/*.htmlBy specifying this directive, the files that have .html extension in the directory /ITSO/itso99/ITSOco /Download are all cached when you start the server ITSO99. (3) FRCACacheLocalFileRunTime /ITSO/itso99/ITSOco/People/*This directive makes all files in the directory /ITSO/itso99/ITSOco/People available to be cached when they are accessed.In this example, the files in the subdirectory Employees are not cached because file name matching is not recursive.(4) FRCAEnableProxy On This directive enables FRCA proxy.(4) FRCAProxyPass /servlet/ http://10.5.92.14:8080/servlet/In this example, specifying /servlet in URI causes to run a servlet on the application server. By specifying the directive FRCAProxyPass like this example, the result of the servlet can be cached in the NFC for certain period, that is specified by the directive frcaproxycacherefreshinterval.Note: In this directive of the example, the target URL has the same IP address and port as the ones this server listens.In this case, FRCA should understand that this URL is of the same server, and passes the request to the correct route without any looping problem.

(4) FRCAProxyCacheRefreshInterval /servlet/ 300As described above, this directive specifies the interval of refreshing cached data of FRCA proxy.(5) FRCAProxyPass /cgi-bin/ http://as21.itsoroch.ibm.com:9999 /cgi-bin/By specifying this directive, the request for CGI program is rerouted to the target host as21.itsoroch.ibm.com:9999, that is different iSeries, and the result is cached in the NFC in the source system.
