  • 1.  Tech Tip: CA IDMS Sharing a SVC number between different releases

    Problem:

    After IPL and the successful installation of the new SVC with CAIRIM, all old version CV startups abend with

    "DC170202 CA-IDMS - SVC MUST BE INSTALLED BY CAIRIM BEFORE STARTING THE DATABASE."

    The old and the new CV’s are using the same SVC number.

     

    Resolution:

    The SVC's are downward compatible so you should be able to run with a newer release using an older release of IDMS.

    This requires the SVC to be coded twice in CAIRIM for both releases with the second occurrence using REFRESH. Here's an example for 18.5 and 19.0:

     

    PRODUCT(CA IDMS) VERSION(GJI5) INIT(GJJ0INIT) PARM(SVC=248)

    PRODUCT(CA IDMS) VERSION(GJJ0) INIT(GJJ0INIT) PARM(REFRESH(SVC=248))

     

    The first statement installs SVC 248 with version code GJI5 (Release 18.5), the second statement will insert version code GJJ0 (Release 19.0) into the CPU you run CAIRIM on while 'refreshing' the same SVC load module.

    This will allow 18.5 and 19.0 CA IDMS CVs to use the same SVC number.

     

    Additional Information:

    CA IDMS Release 19.0” Chapter “Starting Your Product”  Section “Post-Configuration Tasks” under “SVC”

    Does the order matter? We are in the middle of an upgrade from 18.5 to 19.0 and the SYS1.PARMLIB member is coded as

     

    PRODUCT(CA-IDMS) VERSION(GJJ0) INIT(GJJ0INIT) PARM(SVC=173)

    PRODUCT(CA-IDMS) VERSION(GJI5) INIT(GJI5INIT) PARM(REFRESH(SVC=173))

    Hi Bob,

      As far as the VERSION parm the order does not matter.

      What matters is that both/all of the statements use the latest INIT module GJJ0INIT and the CAIRIM job's STEPLIB/JOBLIB has just the latest APFLIB members ( GJJ0INIT, CAIXDOA$, IDMSMSVA, PMRTDATA & RHDCSSFM ) as well as the relevant SVC modules.  The SVC and all APFLIB modules are always downward compatible so you should always be loading the latest.
