Editing multijob options for restore

On the Multijob Options panel (BSY$MJOP), you can edit multijob processing options. If Multijob processing was not used for creating the offload, you can still use Multijob processing for restore processing.

Procedure

  1. On the Build Restore Job panel, specify Y (Yes) in the Edit Multijob Options field and press Enter.

 Enter the options for performing Multijob processing:

   LPAR Name          Max Jobs (1-99)       Max Tasks (1-99)          
   RS22               02                    02                        
   RS23               02                    02

  2. Modify the following Multijob options to use for restore processing:
    Use Multijobs
    Specify Y if you want the restore processes to use multiple jobs, or N to use a single job.
    Multijob Prefix
    This is a 1-6 character value that is used as a prefix for the multiple jobs that are created. As each multijob is initiated, the name of the job will begin with this prefix followed by a number from 01-99. If this value is not specified, then the prefix is taken from the first 6 characters of the Master jobname.
    Multijob LPAR List

    The LPAR list allows you to specify up to four entries to be used by the Master job for submitting Multijobs. Each entry consists of an 8 character LPAR name, a 2 character max jobs value, and a 2 character max tasks value.

    Consider the following information when specifying these entries:

    • The same LPAR can be specified more than once in the LPAR List.
    • When defining the LPAR List, be aware of the total number of tape drives that are required for processing if the maximum number of jobs is used. For each LPAR List entry, the maximum number of tape drives used is equal to the sum of the maximum number of jobs multiplied by the maximum number of tasks. In the Multijob Options panel example, this number is 8 (2x2+2x2).
    • Before any Multijobs are initiated, the Master job will determine from the LPAR List entries what the maximum number of jobs is that can be submitted. The Master job will break the recovery units for a recovery into groups so that they can be processed without exceeding the maximum job limit.
    LPAR Name
    This is a 1-8 character LPAR name. It identifies the name of the LPAR on which the Multijob is to be submitted. You can specify a single asterisk (*) to indicate that the LPAR that the jobs will be submitted to is the same LPAR on which the Master job is running.
    Max Jobs
    This is a 2 digit number from 01-99 and indicates the maximum number of jobs that can be submitted for this entry. The Master job will submit Multijobs on the specified LPAR until this limit is reached. When this limit is reached, if more jobs are needed, the Master job will move to the next LPAR List entry. The default value is 4.
    Max Tasks
    This is a 2 digit number from 01-99 and specifies the maximum number of tasks that are to be created in each Multijob for processing. When the Multijob is submitted, it will create as many tasks as are needed, up to this limit, to perform restore processing. The default value is 4.
  3. Press PF3 to return to the Build Restore Job panel and build the restore JCL.
