Changing the load module to reflect the new qualifier

To change the system parameter load module to specify the new qualifier for new archive data sets and the Db2 catalog and directory data sets, you must follow the installation process.

Procedure

To specify the new qualifier:

  1. Run the installation CLIST, and specify INSTALL TYPE=INSTALL and DATA SHARING FUNCTION=NONE.
  2. Enter new values for the fields shown in the following table.
    Table 1. CLIST panels and fields to change to reflect new qualifier
    Panel name Field name Comments
    DSNTIPA1 INSTALL TYPE Specify INSTALL. Do not specify a new default prefix for the input data sets listed on this panel.
    DSNTIPA1 OUTPUT MEMBER NAME  
    DSNTIPA2 CATALOG ALIAS  
    DSNTIPH COPY 1 NAME and COPY 2 NAME These are the bootstrap data set names.
    DSNTIPH COPY 1 PREFIX and COPY 2 PREFIX These fields appear for both active and archive log prefixes.
    DSNTIPT SAMPLE LIBRARY This field allows you to specify a field name for edited output of the installation CLIST. Avoid overlaying existing data sets by changing the middle node, NEW, to something else. The only members you use in this procedure are xxxxMSTR and DSNTIJUZ in the sample library.
    DSNTIPO PARAMETER MODULE Change this value only if you want to preserve the existing member through the CLIST.

    The output from the CLIST is a new set of tailored JCL with new cataloged procedures and a DSNTIJUZ job, which produces a new member.

  3. Run the first two job steps of DSNTIJUZ to update the subsystem parameter load module.

    Unless you have specified a new name for the load module, make sure the output load module does not go to the SDSNEXIT or SDSNLOAD library used by the active Db2 subsystem.

    If you are changing the subsystem ID in addition to the system data set name qualifier, you should run job steps DSNTIZP and DSNTIZQ to update the DSNHDECP or a user-specified application defaults module (parameter SSID). Make sure that the updated dsnhdecp parameter does not go to the SDSNEXIT or SDSNLOAD library that is used by the active Db2 subsystem. Use caution when changing the subsystem ID. For more information, see "MVS PARMLIB updates panel: DSNTIPM" for the discussion of panel DSNTIPM for PARMLIB members where the subsystem ID has to be changed.
