Deactivating CICS global user exit trace

MainView for CICS and MainView AutoOPERATOR use CICS global user exits to gather information from a region. With CICS trace active, the tracing of exits adds overhead and decreases the amount of user information that is available in the incore trace table. You can turn off the user exit trace entries that are generated by MainView for CICS and MainView AutoOPERATOR. However, doing so also deactivates any other user exit trace entries; other products and user code that include user exits are no longer traced.

To turn off user exit tracing, you can:

  • set the SIT parameters SPCTRxx and STNTRxx (where xx is the user exit interface) to suppress component tracing at CICS initialization time:

    • SPCTRUE=OFF (suppress special tracing for user exit interface)

    • STNTRUE=OFF (suppress standard tracing for user exit interface)

  • use the CETR transaction
