Some other weird things to check. 1. Is the cpu increase in DB2? check the DB2 accounting records for this. 2. Someone mentioned Cache issues - that would require the program be compiled without RENT to get working storage in the same memory area - CBT has a program that will extract cobol compile options. 3. brute force method - get a STROBE report and look for where the most cpu is. I know not everyone has STROBE.
