Installation step 6: Define Db2 initialization parameters: DSNTIJUZ, DSNTIJUA, DSNTIJUM, and DSNTIJUL

For Db2 12 installation, you must define initialization parameters in the subsystem parameter module (DSNZPxxx) and application defaults load module (dsnhdecp), define the offline message generator CCSID (DSNHMCID), and update DDF related information in the BSDS.

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 .
  4. Run job DSNTIJUL.
    Job DSNTIJUL runs the Db2 change log inventory (DSNJU003) to update DDF-related information in the BSDS. For more information, see Job DSNTIJUL: update DDF related BSDS information.
