Steps to Reproduce
1) Setup Pega with multiple data sources for their split schema database.
2) Start Pega.
User then reviewed https://pdn.pega.com/support-articles/j2ca0030e-xaresources-error-websphere-logs and disabled TLS as well as configured XA drivers.
System was brought up and issues had disappeared, however, user did not want XA functionality.
Root Cause
The root cause was the unnecessary setup of two data sources for PegaRULES and PegaDATA
Resolution
A single data source is all that is required but not XA configuration.
