Db2 for z/OS DBAs often spend effort to tailor job DSNTIJUZ to run only certain job steps for specific installation and migration activities, such updating subsystem parameters, application programming defaults, or DDF related information in the BSDS.
With APAR PI85657, DB2 12 for z/OS introduces several new jobs for various activities that were previously completed by the single DSNTIJUZ job:
DSNTIJUZ is the existing job. It now only assembles and links a subsystem parameter module (DSNZPxxx).
DSNTIJUA assembles and links a Db2 application defaults module (DSNHDECP).
DSNTIJUM assembles and links the Db2 offline message generator CCSSID module (DSNHMCID).
DSNTIJUL updates DDF related information in the BSDS. This job is for installation only, not for migration.
Separating the actions of the DSNTIJUZ job into several jobs, enables you to choose a job for just the steps that you need for your specific activities, and frees you from the effort of tailoring the DSNTIJUZ job to remove or disable unneeded steps.
