Defining Db2 12 initialization parameters for migrating data sharing members
For migrating data sharing members after the first to Db2 12, you must define Db2 12 initialization parameters in the subsystem parameter module (DSNZPxxx) 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:
For migrating members, the application defaults load module (dsnhdecp) is not reassembled for each subsequent migrating member.
Procedure
To define the Db2 12 initialization parameters, complete the following steps:
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.
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.

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.
