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 Fault Analyzer 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:

TERMTHDACT(TRACE,CICSDDS,...)

This value causes Language Environment® to write its diagnostics to the CICS® transaction dump data set.

TERMTHDACT(QUIET)

This value suppresses most of the Language Environment® diagnostics.
