Migration step 11: Define Db2 12 initialization parameters: DSNTIJUZ, DSNTIJUA, and DSNTIJUM

For migration to Db2 12, you must define initialization parameters in the subsystem parameter module (DSNZPxxx) and application defaults load module (dsnhdecp), and define the offline message generator CCSID (DSNHMCID).

Before you begin

If the Db2 subsystem that you are migrating has only one bootstrap data set (BSDS), add second BSDS before you migrate. For more information, see Adding a second BSDS during migration (optional).

About this task

The subsystem parameter module (DSNZPxxx) and application defaults module (dsnhdecp) names are specified in the following DSNITPO3 installation panel fields:

Procedure

To define the Db2 12 initialization parameters, complete the following steps:

  1. Run job DSNTIJUZ.
    Job DSNTIJUZ defines the Db2 data-only subsystem parameter module (DSNZPxxx), which consists of the expansion of the following macros: DSN6ARVP, DSN6FAC, DSN6GRP, DSN6LOGP, DSN6SPRM, and DSN6SYSP.
    You might need to make the following adjustments before running the job:
    • If you added a STEPLIB DD statement to the Db2 start procedures ahead of prefix.SDSNEXIT and prefix.SDSNLOAD, you can move the SYSLMOD output to that library.
    Important: Start of changeIf the DSNTIJUZ job ends with return code 4, check that any warning messages can be safely ignored before continuing to the next step.End of change
    When DSNTIJUZ completes, the DSNTINST CLIST performs calculations by using the values that you specified for some of the parameter values that you entered on the panels. These calculations appear in the macro descriptions.

    For more information, see Job DSNTIJUZ: define the Db2 data-only subsystem parameter module.

  2. Run job DSNTIJUA.
    Job DSNTIJUA defines the Db2 data-only application defaults module.
    You might need to make the following adjustments before running the job:
    • If you added a STEPLIB DD statement to the Db2 start procedures ahead of prefix.SDSNEXIT and prefix.SDSNLOAD, you can move the SYSLMOD output to that library.

    For more information, see Job DSNTIJUA: define data-only application defaults module.

  3. Run job DSNTIJUM.
    Job DSNTIJUM defines the Db2 data-only offline message generator CCSID (DSNHMCID) module which is needed for message conversion by Db2 applications and utilities. For more information, see Job DSNTIJUM: define Db2 data-only offline message generator CCSID (DSNHMCID) module .
