Role of XML

XML Activities

Parse Palette

Role of EMS

Business Integration Software

Mediates interactions between different applications and databases Allows the automation of business processes Manage transactions and Web Services, Handle exceptions and report errors Provides graphical user interface to configure application services Provides plug-ins for application connectivity Provides interface for administrator to monitor and manage processes and application

resources

Reduces the amount of time and effort to develop and deploy business activities

In BW

In JAVAimport java.io.*;

public class Test {public static void main(String [] args) {

String fileName = "temp.txt";

String line = null;

try {FileReader fileReader = new FileReader(fileName);

BufferedReader bufferedReader = new BufferedReader(fileReader);

while((line = bufferedReader.readLine()) != null) {System.out.println(line);}

bufferedReader.close(); }catch(FileNotFoundException ex) {System.out.println("Unable to open file '" + fileName + "'"); }catch(IOException ex) {System.out.println("Error reading file '" + fileName + "'"); ex.printStackTrace();}

Accelerates the application development and deployment cycle

Functions and data are available as re-usable services to use in complex business processes

Improves the consistency, performance and scalability

Capable of integrating any IT resource virtually

Supports leading standards and protocols including HTTP/S, FTP, JDBC, TCP and JMS

Extensive Web Services capabilities and support for SOAP over JMS and HTTP/S

Enables distribution of information using technology that is best suited for scenario

Provides built-in tool for defining XML schemas, parsing and rendering capabilities

Designed to describe data

Software and hardware independent language for carrying information

One of the most important technologies for business integration both inside and across enterprises

Parse XML: Processes a binary XML file or XML string and turns it into an XML schema based

on the XSD specified

Render XML:Takes an instance of an XML schema element and renders it as a stream of bytes

containing XML or an XML string

Transform XML:Allows us to transform an input XML document into the output specified by the

given XSLT File shared configuration resource

XSLT FileAllows us to load an XSLT file to use to transform XML schemas using the Transform

XML activity

Data Format:

It contains the specification for parsing or rendering a text string using the Parse Data and Render Data activities

Parse Data:

Takes a text string or input from a file and processes it, turning it into a schema tree based on the specified Data Format shared configuration

Render Data:

Takes an instance of a data schema and renders it as a text string. The schema processed is based on a specified Data Format shared configuration

Enterprise messaging allows different systems to communicate with each other

Enterprise Message Service is the TIBCO’s implementation of Java Message Service.

It obey the Java Message Service specifications

Some features like load-balancing, routing and fault tolerant configurations are added to TIBCO EMS

Reduces the cost and complexity of integrating different systems

Increases flexibility and promotes greater service reuse

Improves the performance, scalability and reliability of distributed system communication

File Palette

File palette

CONTENTS:

Copy file

Create file

File poller

List files

Read file

Remove file

Rename file

Wait for file change

Write file

COPY FILE: It used for coping a file.

In input we can give the source file(fromfilename) which is to be copied.

Destination folder (tofilename) at which the copied file is pasted.

Create

create is used to create files and directory

Just we need to give our indented file name or directory name and location as input

FILE POLLER

It is a starter activity

File poller can detect any changes in a file at particular location at regular intervels of time.

The input to the file poller is a location of files or a particular file.

We can also check for a specific event by select the options

LIST FILES

List files is used for listing all the files and directories in a location ie.. Folder.

Input to the list files activity is the desired location.

The output of the list files contains the file name size and last modified date also.

READ FILE

Read file is used for reading the fileThe input to the file will be the file full name.The output of the activity will be the content in the file

REMOVE FILE: Remove file was used to delete the file.

It deletes the file permanently from our system we cant able to find the removed file in recycle bin.

The input to the remove file is the file name we want to remove.

RENAME FILE: Rename file is used for changing a file name.

We can also use the rename file for moving a file.

For renaming a file we have to give the existing file name and desired file name.

WAIT FOR FILE CHANGE It is a non starter process

It pause the process until the changes are made in the location which is specified

WRITE FILE

Write file is used for writing text content into the fileIt can create non existing directories also

What is a Protocol

Http Introduction

Http palette

Groups in TIBCO

Types of Group Actions

Common set of rules and instructions that each computer follows

Hyper text transfer protocol

Application layer protocol

Works as a Request Response model

Usually works on 8080 port in association with TCP protocol and on 80 port with UDP

Used to communicate with web server through HTTP Palettes.

Consists of six activities ( 2 at project level, 4 at process level)

Available at Process Level

Available at Project Level

HTTP Connection: Describes the connection properties . Necessary if we use either HTTP receiver or

wait for HTTP request

HTTP Proxy : Useful when we want to send requests outside the firewall to a proxy server(HTTP)

HTTP Receiver : It is process starter activity which will be triggered once it gets a HTTP request.

Send HTTP Request: Asynchronous activity that sends an HTTP request and waits for a response

from the Web Server

Wait for HTTP Response : Waits for an incoming HTTP request in a process. The process

instance suspends until the incoming HTTP request is received.

Send HTTP Response : Sends a response to a previously received

HTTP request. Activity is used in conjunction with the HTTP receiver process starter or Wait for

HTTP Request activity. default status line returned is "200 OK".

Groups are used to segregate certain actions together.

Used for iterations

Used for repeating a group of activities or a single activity for a specific number of times

Ex: if we want to repeat a sub process for 10 times we will use a group action.

1) Iterate

2) Repeat until true

3) Repeat on error until true

4) Transaction

5) Critical section

6) Pick first

7) While true

8) if

Iterate :• Used to iterate group once for every item in the list• Iterate can be of any number of times depending on the loop condition

Iterate action on a

groupInput Output

Group with a

condition defined

Repeat until true:

• Repeat the iterations until the condition is true

• Once the defined condition is true, it will come out of the loop

• Condition is true then exit

Input

Execute and repeat

LoopFail

Exit Loop

True

Repeat on error until true:

• Used to iterate a group when an error occurs

• If there is no error it is executed only once

• Example would be a password for account

Group with repeat

on error for n times

Input

No Error

Execute and exit

Keep repeating for N times and

exit

Error

Critical Section :

• Synchronize process instances so that only one process instance executes the grouped activities

• Other process keeps waiting until the process instance that is currently executing critical section

completes

Group with critical

section

Process 1

Process 2

Process 1 executes group first

Process 2 keeps waiting until the other is

completed and then executes group

While True:

• Repeat as long as the defined condition evaluates as true

• If the condition evaluates as false exit the group

Group

Evaluate condition

first

InputExecute and repeat

True

Fail

Exit without execution

The Mapper is a synchronous activity that adds a new process variable to the process.

This variable can be an inline schema, primitive element, or a complex element.

The Mapper activity adds a new process variable to the process definition.

Mapper activity is used to convert one XML structue into another XML structure.

It can be used to write your logics.

You can find Mapper Activity in General Activities.

We can always give the input schema structure in the Output Editor of Start activity.

The output schema structure can be specified in the Input Editor of the Mapper Activity.

When an activity is first dragged from a palette to the design panel, the activity’s input elements are displayed as hints. These hints show you the data the activity expects as input. Each element can be required or optional or repeating. Required elements must have a mapping or formula specified.

You map data by selecting an item in the Process Data panel, then drag and drop that item into the desired schema element you wish to map in the Activity Input panel.

When you perform mapping, simple mappings appear in the formula area next to the input element after you release the mouse button. For more complex mappings, the Mapping Wizard dialog allows you to select which kind of mapping you wish to perform.

Most options in the Mapping Wizard dialog are straightforward. However, there are some complex scenarios that require multiple steps.

You can specify XPath formulas to transform an element if you need to perform more complex processing.

The XPath Formula Builder allows you to easily create XPath formulas.

Input: •Output:

There are some statements that are used to convert a hint into a statement without performing any mapping. They are as follows:

Surround With If

Surround With For Each

Surround With For Each Group

Surround With Choice

When you select an element in the Activity Input schema and right-click, a popup menu appears. The Statement menu item contains several sub-items that are useful shortcuts for creating statements.

Surround with If:An if statement is used to surround other statements in an XSLT template to perform conditional processing.

If the test attribute evaluates to true, the statements in the if are output, otherwise they are not output.

Surround with For-Each:A shortcut for moving the current element into a For-Each statement performs the specified statements once for each item in the selected node.

This is useful if you wish to process each item of a repeating element once.

Surround with For-Each-Group:

A shortcut for moving the current element into a For-Each-Group statement and adding a

Group-By grouping statement.

Groups the items in a list by a specified element. This statement requires a Grouping statement

to specify which element to group-by.

You may need to convert a flat list of items into a more structured list. For example, you may

have list of all orders that have been completed. You may want to organize that list so that you

can group the orders placed by each customer.

This scenario typically occurs when you retrieve records from a relational database and the

records must be structured differently.

Surround with Choice:A shortcut for adding a choice statement and its associated conditions or otherwise statements around the currently selected element.

There are four types of variables available in TIBCO BW. They are

Global Variables

Process Variables

Shared Variables

Job shared Variables

Global variables are the static variables and they can be set during the run time.

TIBCO Global variables allow you to specify constants that can be used throughout the project.

Advantages:

1) Easy Reuse of variables in multiple places in the project

2) Easy to change global variables value in TIBCO Administrator.

Process variables are data structures available to the activities in the process.

Scope of the Process variable is with-in the process in which it has been declared.

Assign Activity is used for assigning values to the process variables

Shared variables allow you to specify data for use across multiple process instances.

Scope of the shared variable is it can be used in the entire project.

Get Shared Variable and Set Shared variable activities are used for retrieving and setting the data for a shared variable.

A Job Shared Variable resource is similar to a Shared Variable, but its scope is limited to the current job.

A copy of the variable is created for every instance

It is used for passing data to and from sub-processes .

Get Shared Variable and Set Shared variable activities are used for retrieving and setting the data for a shared variable.

A database is an organized collection of data so that we can access the data easily.

It stores the data in the form of files. It can store data in the form of tables, but there will be no relation between the tables. So, we go for Relational Data Base management systems.

SQL stands for Structured Query Language. SQL is the standard language for relational database management systems.

SQL Commands:

Create

Select

Insert

Update

Delete

Drop

Activity Action

JDBC Query Performs the specified SQL SELECT

statement

JDBC Update Performs the specified SQL INSERT,

UPDATE, or DELETE statement.

SQL Direct Executes an SQL statement that you supply

JDBC Call Procedure calls a database procedure or function using

the specified JDBC connection.
