Pega PRPC

1. Pega PRPC Installation procedure
2. Change PRConfig.xml file settings
3. Configure Workflow: HOW TO CREATE AN XPDL OR BPEL REPRESENTATION OF A FLOW RULE

1. Change PRConfig.xml file settings
Each node of a Process Commander cluster has a file named prconfig.xml that holds the configuration settings for an installation. The file is loaded on startup and to determine information including:

You can modify many of the default installation settings by accessing the prconfig.xml file as described below.

Stop the Process Commander application.
Undeploy the Process Commander application.
Extract the prconfig.xml file from one of the following locations:
If Process Commander is deployed as a Web application, locate and unzip the prweb.war file to a location that you have access to. Then extract the prconfig.xml file from the WEB_INF\classes directory.
If Process Commander is deployed as an enterprise application, locate and unzip the prresources.jar located in the APP-INF\lib directory. Then extract the prconfig.xml file from the .jar file.
Open the prconfig.xml file in a text editor.
Add the entries you need.
Save the file and repackage the modified prconfig.xml file into the prweb.war or prresources.jar file, as appropriate.
Redeploy Process Commander.

2.sample flow rule diagram
The standard Work-.New harness includes the standard CoreParty and PartyDisplay sections that your operators can use to add work parties on the New form of a work object.

1) create operators who uses workflow
2) create properties which are used in work flow
3)create activities used in workflow
5)Draw flow rule diagram using the stencils provided by pega business modellor
6) Go to Process Commander XML to see representation of the flow in XML.
7) You can also edit the xml to change flow or covert into BPEL or XPDL both are supported wfc standards.
8) Write supporting java classes for customised tasks and inherit them
9) You can configure email adapters, outlook connectors by using wizards or connectors of pega.We can also use integration capabilities like JMS,MQ,CORBA etc..if needed with legacy system communication in message routing.Also can generate services.
10) save your work flow and publish.
