Updating Db2 initialization parameters for function level activation
After you activate a function level, you can enable applications to begin using new capabilities by default by updating the APPLCOMPAT subsystem parameter and the SQLLEVEL value in the application defaults module.
About this task
Tip: Do not raise the default application
compatibility level of the Db2 subsystem
immediately after migrating or activating a new function level. Instead, wait until applications
have been verified to work correctly at the higher function level, and any incompatibilities have
been resolved.
For details, see Enabling default application compatibility with function level 500 or higher.
Procedure
To update initialization parameters for function level activation, 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.
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.
