10.1 Parameter Modification

Parameter modifications are described below.  The parameters
themselves are documented in Chapter 7 of this guide.  The
checklists in this section are to be used when changing the
CA MICS TSO Analyzer after it has been installed and running.
They are not intended to be used for installation purposes.

For a more thorough description of the tasks to perform,
refer to Chapter 6 in the CA MICS System Modification Guide.
Chapter 6 discusses database tailoring.


Modifying TSOGENIN
------------------

The TSOGENIN member of sharedprefix.MICS.GENLIB controls the
key structure and element content of the product files,
including activating account codes for the Analyzer.  Before
making any changes to this member, carefully review the
description of the CA MICS Component Generator in Chapter 4
of the System Modification Guide.

___ 1.  Save a copy of sharedprefix.MICS.GENLIB(TSOGENIN) in
        sharedprefix.MICS.LOCALMOD.CNTL for recovery
        purposes.

___ 2.  Code your TSOGENIN changes in IEBUPDTE format.

___ 3.  Update sharedprefix.MICS.GENLIB(TSOGENIN) using
        IEBUPDTE to apply the change.  Be sure that the step
        completes with a condition code of zero and that the
        updates applied as expected.

___ 4.  Submit sharedprefix.MICS.CNTL(TSOCGEN) to implement
        the change.

___ 5.  If you activated files, complete the steps in the
        Modifying DBMODEL checklist in this section.  If you
        did not activate files, this checklist is complete.


Modifying TSOACCT or TSOACRT
----------------------------

Changes to TSOACCT may be required to increase the length of
an account element.  It is also possible to add, delete,
change the sequence, or change the timespans at which an
element exists.

Since these types of modifications can impact update
processing, you should contact CA Product Support before
attempting them.  Also, changes of this type may require
modifications to sharedprefix.MICS.PARMS(TSOACRT).

___ 1.  Save a copy of sharedprefix.MICS.PARMS members
        TSOACCT and TSOACRT in
        sharedprefix.MICS.LOCALMOD.CNTL for recovery
        purposes.

___ 2.  Edit sharedprefix.MICS.PARMS(TSOACCT) and make any
        required changes.

___ 3.  Submit sharedprefix.MICS.CNTL(TSOCGEN) to implement
        the change.  This completes this checklist.

___ 4.  If necessary, edit sharedprefix.MICS.PARMS(TSOACRT)
        and make any required changes.  Please note that
        changes made to this member take effect immediately.

Modifying DBMODEL
-----------------

The DBMODEL member controls the cycle retention limits for
all files in the unit.  Activating a file or adding a file to
a new timespan also requires changes to TSOGENIN.

___ 1.  Save a copy of prefix.MICS.PARMS(DBMODEL) in
        sharedprefix.MICS.LOCALMOD.CNTL for recovery
        purposes.

___ 2.  Edit prefix.MICS.PARMS(DBMODEL) and make any required
        changes.

___ 3.  If necessary, perform steps 4 through 7 to reallocate
        the database unit files.  Otherwise proceed to step
        8.

___ 4.  If necessary, submit prefix.MICS.CNTL(BACKUP) to
        obtain a current backup of the unit.

___ 5.  Delete the following data sets:

          prefix.MICS.CHECKPT.DATA
          prefix.MICS.DETAIL
          prefix.MICS.DAYS
          prefix.MICS.WEEKS
          prefix.MICS.MONTHS
          prefix.MICS.YEARS

___ 6.  Edit prefix.MICS.CNTL(ALLOCATE) to specify the new
        data set space requirements and submit.

___ 7.  Submit prefix.MICS.CNTL(RESTORE) to restore the data
        sets.

___ 8.  If the cycle retention limits have been changed,
        submit prefix.MICS.CNTL(CYCLEGEN) to make the changes
        effective.
