Minimizing the time Language Environment spends writing dump output to transient data queue CESE

The Language Environment® runtime option TERMTHDACT controls the type and amount of diagnostic output produced by Language Environment for an unhandled error.

Using TERMTHDACT(DUMP), TERMTHDACT(TRACE), TERMTHDACT(UADUMP), or TERMTHDACT(UATRACE) can create a significant overhead in a production environment. These settings can cause large amounts of traceback and Language Environment dump data to be written to the CESE transient data queue.

If a traceback or CEEDUMP is not needed by the application environment, use TERMTHDACT(MSG) to eliminate the performance overhead of writing formatted CEEDUMPs to the CICS® transient data queue CESE. If the traceback or CEEDUMP is required by the application, specify the CICSDDS option of TERMTHDACT to direct the Language Environment diagnostic output to the CICS dump data set, rather than to the CESE transient data queue.
