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.
You run job DSNTIJUZ as part of the following Db2 installation, migration tasks, and Db2 12 function-level activation tasks:
- Installation step 6: Define Db2 initialization parameters: DSNTIJUZ, DSNTIJUA, DSNTIJUM, and DSNTIJUL
- Defining Db2 initialization parameters for enabling data sharing
- Defining Db2 initialization parameters for new data sharing members
- Migration step 11: Define Db2 12 initialization parameters: DSNTIJUZ, DSNTIJUA, and DSNTIJUM
- Defining Db2 12 initialization parameters for migrating data sharing members
- Updating subsystem parameter and application default values
- Updating Db2 initialization parameters for function level activation
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
- 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.
