Job DSNTIJUZ: define the Db2 data-only subsystem parameter module

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.

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.

The subsystem parameter module consists of the expansion of the following macros that contain the Db2 run-time parameters that you selected by using the ISPF panels:

  • DSN6ARVP
  • DSN6FAC
  • DSN6GRP
  • DSN6LOGP
  • DSN6SPRM
  • DSN6SYSP

You might also be directed by IBM to run it when applying service to Db2. In Db2 data sharing, each member of the group must have its own subsystem parameter module and therefore its own DSNTIJUZ job.

DSNTIJUZ also contains a disabled job step, DSNTIMQ, that can be enabled to set up GENASM entries in SMP/E for the Db2 system parameter (DSN6xxxx) macros. The GENASM entries cause service to any of these macros to trigger SMP/E to initiate a reassembly of the Db2 system parameter module. Advanced SMP/E skills are recommended for using GENASM entries. See the warnings in the comment block for job step DSNTIMQ before enabling it.

Adjustments to job DSNTIJUZ

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.
