Dynamically Upgrade from 12.0 to 12.6

To use the features of the release 12.6, you can upgrade from 12.0 to 12.6.

If your TMC is in the old format and you are using the TMSVOLDF usermod to build TMSUX2E and TMSUX2U to do the alphanumeric volser conversions, apply r12.0 PTF RO32245 and r12.6 PTF RO32864. If possible, use TMSXTEND to convert your TMC to the new format so that the exits are not needed. You can contact CA Support for help on the conversion.

Note: If you have installed any of the CA 1 z/OS usermods from a previous release, they can continue to be used until the next scheduled IPL at which time we recommend that you put in the r12.6 usermods. These usermods include the failsafe usermod, CBRXUENT, CBRUXEJC, CBRUXVNL, and IGXMSGEX.

Follow these steps:

  1. Stop tape processing and back up the TMC and Audit data sets using your currently installed version of TMSCOPY.
  2. Remove the CA 1 catalog intercept by running the CAS9 procedure with the following control statements for CA 1 in CARIMPRM pointing to the 12.0 libraries: 
    PRODUCT(CA 1/MVS) VERSION(L0C0) INIT(L0C0INIT) -
PARM(REINIT,COSI=NO) -
LOADLIB(hlq.ca1.r120.CTAPLINK)
  3. Stop CTS if active.
  4. Deactivate CA 1 by starting 12.0 TMSINIT and replying with the system password. This process removes the 12.0 OSI intercepts.
  5. Back up the 12.0 load library.

    Note: Backing up is needed when you have to remove 12.6 dynamically. A new load library is created during the installation of 12.6. Empty the 12.0 library. Copy the entire contents of the 12.6 library into the current 12.0 link-listed library and issue a F LLA REFRESH.

  6. Load 12.6. dynamically by executing the CAS9 procedure with the following control statements for CA 1 in CARIMPRM: 
    PRODUCT(CA 1/MVS) VERSION(L0C6) INIT(L0C6INIT) -
PARM(REINIT,LPA=ALL,SVC=xxx,SMF=YES) -
LOADLIB(hlq.ca1.r126.CTAPLINK)

PRODUCT(CA 1/MVS) VERSION(L0C6) INIT(L0C6INIT) -
PARM(REINIT,COSI=YES) -
LOADLIB(hlq.ca1.r126.CTAPLINK)

    Note: For a future IPL, insert the 12.6 load library in place of the 12.0 load library in the link-list concatenation.

  7. Using the 12.6 options library, start the 12.6 TMSINIT to activate CA 1.
  8. Start CTS if previously active.
