Summary

PegaRules engine start fails to initialize with an error after upgrading from Pega 7.1.6 to Pega 7.1.9 using Install and Update Assistant (IUA) on split schema.

Error Messages

com.pega.pegarules.pub.runtime.IndeterminateConditionalException: Executable.evaluateWhen-Exception Encountered a :java.lang.NullPointerException
at com.pega.pegarules.session.internal.mgmt.Executable.evaluateWhen(Executable.java:4101)

Steps to Reproduce

1. Upgrade from Pega 7.1.6 to Pega 7.1.9 in split schema mode.
2. Start an instance.

​

Root Cause

A defect in Pegasystems’ code or rules.
If the Batch Requestor Type has custom Access Group containing certain Roles like, PegaRULES:SysAdm4, PegaRULES:AutoTest, and so on, it can lead to this issue after an upgrade during first engine initialization.

Resolution

Perform the following local-change:
 

1. Modify the Batch Requestor Type on the pre-upgraded environment, and give it a default Access Group PRPC:Agents.
2. Run the upgrade again, or move the database table record corresponding to the Batch Requestor Type from pr_data_admin from the source to the upgraded system after changing the access group to PRPC:Agents.
