Preparing the Process Commander server

MQ facilities depend on an IBM SupportPac® library. On some WebSphere systems, this file is already installed. Q-1458. If it is not installed, download the library for your server platform from:

http://www-1.ibm.com/support/docview.wss?uid=swg27007197

1. Install the client application according to the instructions for your application server.
2. Note the complete path to the com.ibm.mq.jar file and the connection.jar file.
3. Add both jar files to the Process Commander compile time and runtime class paths. See Pega Developer Network article PRKB-20931 About the Process Commander class paths.

Development procedure

1. Confirm that the initServices/initMQ entry in the prconfig.xml file to set Value="true".

2. Service MQ rules run in a background requestor that uses the APP requestor type to sign on. Development requires:

• A service package data instance (Data-Admin-ServicePackage) to define the package name.
• An MQ Listener data instance to specify the name and properties of the remote queue of the WebSphere MQ server where the service request messages are read from.
• An MQ Server data instance defines the environment properties needed to connect to the WebSphere MQ server.
• A collection of Service MQ rules, each referencing a service activity.

One MQ Server instance can be used by multiple MQ Listener instances, and one MQ Listener instance can be used for all Service MQ instances of a specific customer package and class.

3. The development process involves designing the interface, deploying the service, and then interacting with the MQ service as necessary.

For clients to interact with the Process Commander MQ services, they create client-side request messages, place them on the remote queue that Process Commander listens on, and wait for a response message from Process Commander.

CCSID Value

The coded character set identifier (CCSID) for MQ messages to and from Process Commander is the default value 819. SR-3559 B-20747 and can't be changed

Performance statistics

Through changes the prlogging.xml file, you can obtain performance statistics on the execution of services. See Performance tool — Statistics for services. C-2432

Through changes to the prconfig.xml file, you can be alerted to unusually long service operations. See How to detect lengthy service operations. C-2432
