System performance degrades during startup post upgrade



Pega 7.1.7 is upgraded to Pega 8.2.2.

The system consists of two nodes which run on WebLogic Server for an Oracle database.

The servers runs on VMWare Image while Oracle runs on a physical machine.

System performance degrades during startup (takes more than 40 minutes to startup).

Steps to Reproduce

Restart the WebLogic Server.

Root Cause

Database IO caused the startup bottle neck.


As a local-change, allocate sufficient resources to the application.
