Steps to Reproduce

Log in to the application and perform refresh.

Root Cause

The root cause of this problem is software use or operation error. The database backup was imported on top of an existing environment, with replace option. It seems like there are still residual fragments of prior environment which cause issues.


This issue is resolved by making the following change to the operating environment: 

1. Re-export the pegarules schema from the production system.

2. In pre-prod, drop the pegarules schema user entirely. Recreate pegarules user with same privileges as production's pegarules user has.

3. Import the pegarules schema.

4. Truncate cache tables.

5. Redeploy EAR and start system.
