You're close. You need to run tmsinit to disable CA-1 and also there are a couple health checks that you need to disable. There is a section in the CA-1 manual on deactivating CA-1 right after the section on activating it, and in fact I just did this two weeks ago at a site I manage that changed from CA-1 to RMM, which turns out is now FAR cheaper than CA-1, at least for this client.
Deactivating CA 1 Last Updated August 30, 2023 TMSINIT can deactivate CA 1 by responding with the CA 1 system shutdown value to the IEFTMS0 WTOR. PARM=NODATE cannot be specified. TMSINIT (without the TEST parameter) must be used to reactivate CA 1 if it has been deactivated by using the shutdown value. The operator responds U to the IEFTMS0 message. If hlq .CTAPOPTN is not present or the TMC or Audit data sets have been corrupted and TMSINIT cannot be initialized, CA 1 must be deactivated to correct the error. In this case, CA 1 can be deactivated by specifying TMSPARM DD DUMMY or by omitting TMSPARM DD from the TMSINIT JCL. To deactivate CA 1 without an IPL, you might need to deactivate two of the CA 1 health checks to prevent abends if the health checks are running simultaneously with your deactivation of CA 1 . Use the following commands: F hzsproc DEACTIVATE,CHECK=(CA_1,CA1_FREE_DSNB_QUICK_SCAN) F hzsproc DEACTIVATE,CHECK=(CA_1,CA_USED_DSNB_FREE_CHAIN) Deactivating Realtime Expiration To deactivate the Realtime Expiration feature you must remove the TMSRDS DD statement from the TMSINIT procedure. This deactivates the Realtime Expiration feature only on the system where TMSINIT is run. To deactivate the feature entirely in your shared TMC environment, run TMSINIT with the TMSRDS DD removed on every system. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
