Determine Current Disk Allocation for Existing CA CSM Database Areas

You can use this procedure to determine the current database allocation of your site and prepare to make appropriate changes to the CA CSM upgrade job stream.

Note: You need to perform the steps in this procedure before you submit any jobs in the samplib data set.

Follow these steps:

  1. 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.
  2. Run the Directory (CXX) Space report.

    Use the Directory (CXX) Report Sample JCL to produce a space report for CA CSM DBID 4000.

    Information is generated about the number of tracks allocated to a CA Datacom/MSM area and other important space utilization information. Enter TYPE=A for the keyword and value in the control statement to produce this information.

    Note: For more information about the functions of the Directory (CXX) report, see the chapter REPORT (Generate Reports) in the CA Datacom/DB DBUTLTY Reference Guide z/OS. The information in this guide also applies to CA Datacom/MSM.

  3. Review the output of the Directory (CXX) Space report to analyze disk space.

    Note: You can look at the Directory (CXX) Report Sample JCL.

    The report shows the data area name (three characters). Each data area is associated with a mainframe data set. The data area name is the suffix of the associated data area data set name found in the DD card of the JCL.

  4. For each of the data areas, identify the percentage full and the number of allocated tracks.
