Which programs should be running in R12 that assist with performance?

Hi everyone.  I came across an issue in our test instance that turned out to be us not having the program "Purge Concurrent Request and/or Manager Data" running.  Turns out some payable programs do a full table scan on this table which slowed us down tremendously.

Does anyone have the inclusive list of programs that should be running in an instance of EBS R12?

Thanks for the time
