Adjust Disk Space Manually

Adjusting the disk space manually requires you to do the following:

• Back up your data
• Delete the associated data set
• Reallocate the data set
• Initialize
• Reload the data

Follow these steps:

1. Run Directory (CXX) report to determine current disk allocation.
2. Ensure that all activity requiring the use of the CA CSM database is stopped, including bringing down your CA CSM application server and the CA Datacom/MSM server regions associated with the CA CSM database.

   Bring down your CA CSM application server and the CA Datacom/MSM server:

   • Stop the CA CSM application server.
   • Submit the MSMDBSVP JCL member or MSMDBSRP PROCLIB member to stop (pause) the CA Datacom/MSM server.
3. Ensure that CA Datacom/MSM is active.
   1. Enter the following online console command:

      /F dbjobnm,STATUS
      

      dbjobnm

      Specifies the CA CSM multi-user facility (MUF) executable job name.

      A console DB status command is issued. The output from this command is displayed on the mainframe console, as well as in the SYSOUT class JESMSGLG of the CA Datacom/MSM job.

      If CA Datacom/MSM is active, the following informational message appears:

      DB01327I - MULTI-USER AVAILABLE
      

   2. If necessary, take appropriate action for any other messages that appear.
   3. If CA Datacom/MSM is not active, you can submit the job member MSMMUFS from the samplib data set to bring up the CA Datacom/MSM environment.
4. Run the CA Datacom/MSM DBUTLTY BACKUP function to back up the CA Datacom/MSM database (DBID 4000). You can use the member B4KBKUP in the samplib data set to model from and build a backup job stream.
5. After you have successfully created a backup of your CA Datacom/MSM database, delete the associated CA CSM database (DBID 4000) area and index data sets using TSO or an IBM utility.
6. Reallocate the CA CSM Database (DBID 4000) area and index data sets, with new disk allocations, using one of the following methods:
   • TSO
   • IBM utility
   • Include data set names as part of the CA Datacom/MSM DBUTLTY INIT job stream
7. Run a CA Datacom/MSM DBUTLTY INIT and LOAD function using the current backup performed in the DBUTLTY BACKUP step. You can copy the member B4KLOAD in the samplib data set and customize it to restore the CA CSM database.

   The disk allocation is adjusted and you are ready to provide the necessary space to accommodate your site's CA CSM activity.

   Note: Ensure that you replace the input DD card with the current backup created in the previous step.

8. Run the Directory (CXX) report to confirm that you have made your changes successfully.
9. Bring up the CA Datacom/MSM server and your CA CSM application server.

   CA CSM is ready to be used for normal operations.
