The IDMS Tools Exit Management changed as of 18.0. In the IDMS 18.0 Release Notes, chapter 8, titled CA IDMS TOOLS, it contains a section entitled “Simplified Tools Exit Management” which states:
"You no longer need to link CA-supplied exits with your RHDCUXIT module. All tools exit routines are loaded and managed independently from RHDCUXIT. This
means you no longer need to relink your RHDCUXIT module if maintenance or release upgrades change one of the tools exit routines.
Another benefit of the simplified tools exit management in Version 18.0 is that you no longer need to tailor a USFUEXT module to identify exits to be invoked after the tools exits. Instead, you define your exits using the normal facilities for identifying numbered exits just as if no tools exits were involved."
As a result, MASTERKEY exits (SSK2IT04 and SSK2IT06) have been replaced with a IDMS startup parameter in SYSIDMS:
MASTERKEY_EXITS = ON
For TASK ANALYZER exits (USFEXTD, USFEXTF, USFEXTW, USFEXT0, USFEXT3, USFEXT4, USFEXT5); these have been replaced with the IDMS startup JCL SYSIDMS parameter TASK_ANALYZER_EXITS=ON.
For Adsalive (USG) the exit was USG2333 and at IDMS 18.x, no exit is required as the functionality has been incorporated into the ADSALIVE product.
