Steps to Reproduce

  1. Clone the DB from one environment to another.
  2. Configure the application server to host the Pega application, and connect to the PegaRULES database.

Root Cause

A defect or configuration issue in the operating environment.

Out-of-the-box Pega comes with two Data-Admin-System records - prpc' and 'pega'.

The default prconfig.xml contains an entry for 'pega' system name:
<env name="identification/systemName" value="pega" />

and the Batch requestor references this 'Pega' System name:

If prconfig.xml or Data-Admin-System records point to a different System name such as DEV1, the corresponding Batch, Browser, App and Portal Requestors should also be present for this DEV1 system name.

One can see the System name records in the DB from this SQL:

select distinct pysystemname from pr_data_admin where pxobjclass like 'Data-Admin-Requestor';


Perform the following local-change steps:
  • Ensure that the System name used by prconfig matches the entry in the database.
  • Clone the database from an environment that is working correctly.
  • Ensure the PegaRULES database and the new Websphere environment are also configured similarly.
