Activating Db2 function levels by using z/OSMF

You can use z/OSMF workflows to automate the running of jobs for activating new capabilities in Db2 function levels.

Before you begin

Important: Before you activate function level 500 or higher for the first time, read Activating Db2 13 function level 500 or higher.

Ensure that no incompatible applications will interfere with the catalog update. For details, see Identifying applications that are incompatible with catalog updates.

Determine the function level to activate. In most cases, you can activate a higher function level without separately activating each lower function level above the currently activated function level. However, activating a higher function level also results in the activation of all lower function levels. Before activating a function level, familiarize yourself with the new capabilities and changes that all lower function levels introduce:

About this task

You can run the jobs for activating new capabilities in Db2 function levels by using z/OSMF workflows.

Procedure

To activate a Db2 function level by using z/OSMF, complete the following steps:

  1. Issue a DISPLAY GROUP command to check that the code level of the Db2 subsystem or each data sharing group member supports your target function level.
    In the DSN7100I message, the DB2 LVL column indicates the code level. For more information and examples, see Determining the Db2 code level, catalog level, and function level.
  2. If necessary, apply maintenance, such as PTFs and RSUs, to bring your Db2 subsystem or data sharing group members up to the required code level for your target function level.
  3. Run the installation CLIST, as described in Generating tailored Db2 13 installation, migration, or function level activation jobs.
    1. On panel DSNTIPA1, specify YES in the USE Z/OSMF WORKFLOW field.
    2. On panel DSNTIPA1, specify ACTIVATE in the INSTALL TYPE field.
    3. On panel DSNITP00, specify the target function level in the TARGET FUNCTION LEVEL field.
      The format is VvvRrMmmm, where vv is the version, r is the release, and mmm is the modification level.
      The value is used in the ACTIVATE command in the DSNTIJAF job and the CATMAINT utility control statement in the DSNTIJTC job.
  4. In z/OSMF, run the DSNTIWAF workflow.
    The DSNTIWAF workflow always runs the DSNTIJAF job to run an ACTIVATE command for the target function level. It runs various other jobs depending on the specific situation.
