I have a doubt, actually last week one of the CICS transaction which is using the DB2 failed. The transaction actually has to process 600 records, but it processed only 450 records. There is no problem with the logic of program as it is working fine in the production in all the days. I would like to know if there is any DB2 sub system level mishap will it cause such sort of problems, I mean theproblem can occur without giving any abend. Please help me in this regard how to find information at the subsystem level.
