Investigate tasks that may be holding an RLS lock for an excessive amount of time. The online history component of OMEGAMON/CICS can be used to identify transactions that have been abnormally terminated by CICS due to VSAM timeout conditions (abend code AFCV). If the lock activity is determined to be normal, consider increasing the DTIMOUT value for transactions that use the file, or the FTIMEOUT value defined to CICS.
