Preventing LE from causing the CICS trace to wrap

When a CICS® transaction abends and Language Environment® is active in the abending enclave, Language Environment by default writes diagnostic information to a transient data queue named CESE. This situation occurs if the IBM-supplied Language Environment default runtime option TERMTHDACT(TRACE) is in effect. Because these diagnostics are recorded before Z Abend Investigator receives control to process the abend, the CICS trace table is liable to wrap around, and application trace data might therefore be lost. Depending on your level of MVS™, it is recommended that the TERMTHDACT option is set to one of the following:
This value causes Language Environment to write its diagnostics to the CICS transaction dump data set.
This value suppresses most of the Language Environment diagnostics.
