Defining Db2 initialization parameters for new data sharing members

For new data sharing members, you must define Db2 13 initialization parameters in the subsystem parameter module (DSNZPxxx) and application defaults load module (dsnhdecp).

Before you begin

• Determine appropriate subsystem parameters values for the new Db2 data sharing member. In many cases, the same settings must be used on every member. For more information, see The scope and uniqueness of Db2 subsystem parameters in data sharing.

To define Db2 initialization parameters for new data sharing members, 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: If the DSNTIJUZ job ends with return code 4, check that any warning messages can be safely ignored before continuing to the next step.
   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 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.
