10.1.7 Change the Number of Work Files for DAYnnn

   NOTE:  nnn  is 090 for VCA component
               or 095 for HSM component
          ccc  is VCA or  HSM component

Follow the checklist below to change the number of work files
used in the CA MICS Space Analyzer or its HSM component:

   ****************************************************
   *                                                  *
   *  CHECKLIST 1  - CHANGE NUMBER OF WORK FILES      *
   *                                                  *
   ****************************************************

___ 1.  Update the WORK statement in
        prefix.MICS.PARMS(cccOPS) to specify the number of
        work file pairs required.

       +----------------------------------------------------+
       | Reference 7.3.1 for VCA Processing options (VCAOPS)|
       |           7.3.2 for HSM Processing options (HSMOPS)|
       +----------------------------------------------------+

        Below is an example:

         WORK n XXX pppp ssss

         where: n (0-9) is the number of SAS WORK data sets
                XXX  is TRK or CYL
                pppp is the primary allocation
                ssss is the secondary allocation

         examples: 1) WORK 6 TRK 800 100
                   2) WORK 4 CYL 100 20

         In example 1, 6 SAS WORK data sets are specified,
         each with 800 tracks primary and 100 tracks
         secondary allocation.

         In example 2, 4 SAS WORK data sets are specified,
         each with 100 cylinders primary and 20 cylinders
         secondary allocation.

         You should specify the minimum number of WORK
         data sets to meet your work space requirements.
         As a start, try specifying 2 or 3 work data sets.


___ 2.  If this is the first time you are implementing
        multiple work files in CA MICS Space Analyzer or its
        HSM component, then continue with Step 2.  If you are
        just changing the number currently in use, or simply
        the space definitions, then proceed to Step 3 of this
        checklist.

        Browse sharedprefix.MICS.PROTOLIB(DYcccnnn) checking
        for the presence of the WORK symbolic on the EXEC
        statement to determine if you have previously
        modified this product to increase the allocation of
        SAS WORK space.

___ 2a. If you find a WORK symbolic, simply divide the
        primary and secondary allocation values from the WORK
        symbolic by the number of work files specified above
        (value of n on the WORK statement coded in step 1).

        Coding the resulting values will yield the same
        aggregate space allocation you have been using with a
        single SAS WORK file.  To double your available WORK
        space, carry out the division, double the results and
        use the values in the WORK definition above.

___ 2b. If you did not find a WORK symbolic in PROTOLIB,
        examine prefix.MICS.PARMS(JCLDEF) for each CA MICS
        unit containing the desired VCA or HSM component.
        Find the WORKSPACE keyword.  The space allocation
        specified is used for a single SAS WORK file.
        Perform the same division as described in the
        previous paragraph to determine the quantity that
        will yield equivalent total allocation with multiple
        WORK files.  Then adjust the values upward to meet
        your needs.

___ 3.  Submit the job in prefix.MICS.CNTL(cccPGEN).


___ 4.  Edit prefix.MICS.PARMS(JCLGENU) so that it contains a
        single line that reads:

        DAILY

___ 5.  Submit the job in prefix.MICS.CNTL(JCLGENU).  Ensure
        that there are no error messages in MICSLOG or
        SYSTSPRT, that the MICSLOG contains the normal
        termination message, BAS10999I, and that the job
        completes with a condition code of zero.

___ 6.  The following operational jobs have changed:

        DAILY

        If your site has implemented the operational CA MICS
        processes in a scheduling product, the jobs may
        have to be refreshed in that product.  See the
        scheduling product's administrator for the exact
        processes involved in updating that product's
        representation of the CA MICS jobs.
