Updating Db2 address space definitions for data sharing members to z/OS: DSNTIJMA

For data sharing members after the first, you must update the z/OS system procedure libraries for the Db2 13 address spaces.

Before you begin

The authorization ID that runs the jobs must have authority to update the target system PROCLIB. You can enter that library name on installation panel DSNTIPW in the SYSTEM PROCEDURES field. You might want to use a procedure library other than SYS1.PROCLIB for the procedures.

Examine the updates from job DSNTIJMA carefully before you run it. Also, you might have additional procedures of your own to rename.

Procedure

To update the Db2 address space definitions to z/OS:

Tailor and run job DSNTIJMA.

Job DSNTIJMA renames and replaces the startup procedures in the target system procedure library for the following Db2 address spaces, where ssnm is the subsystem name:

system services address space (ssnmMSTR)
database services address space (ssnmDBM1)
DDF address space (ssnmDIST)
administrative task scheduler stored procedure address space (ssnmADMT)
IRLM address space (irlmproc)

Examine the size of the private area on the Db2 startup procedures. If necessary, modify the procedures to satisfy the requirements for environmental descriptor manager (EDM) pool size, buffers, number of data sets open, and amount of available private address space. For more information, see Calculating working storage requirements.

The STEPLIB concatenation of the database services address space (ssnmDBM1) procedure includes a commented-out DD for the IBM® Language Environment® data sets SCEERUN and SCEERUN2. If your system does not include SCEERUN and SCEERUN2 in the system link list, you must uncomment this DD.
