1. THE CA MICS APPLICATION EXTENSION FOR ASTEX › 1.6 Installation and Operation

1.6 Installation and Operation

Be sure to review Sections 1.4 and 1.5 of this guide before
proceeding to the installation checklists in the CA MICS
Planning, Installation, Operation, and Maintenance Guide
(PIOM).  These sections provide helpful information about the
data sources and the input parameters you will need to supply
for proper installation of this application extension.

We recommend initially installing this application extension
in a TEST unit.  Select about one hour of representative
measurement data for each ASTEX input source.  Analysis of
the data in the TEST unit can provide useful information for
coding the DATA statements in DBMODEL (Section 1.5.2.5 of
this guide).  After tests are complete, install this product
in your production CA MICS environment.

If you prefer to limit the amount of data set and job data in
CA MICS, there are two ways to do so:

o Decrease the number of data sets and jobs ASTEX manages

  To decrease the number of data sets and jobs managed by
  ASTEX, modify the MLSIZE parameters in ASTEX.  ASTEX will
  work from the top down in deciding which data sets and jobs
  not to manage, meaning that the busiest data sets and jobs
  will be managed.  Note:  this method decreases the data
  set and job data in both ASTEX and CA MICS.

o Delete or consolidate volume-specific I/O

  To delete or consolidate volume-specific I/O (I/O to the
  volume VTOC and the volume VVDS), create a USRSADS user
  exit in prefix.MICS.USER.SOURCE using the guidance provided
  in Sections 4.3.1 (coding restrictions) and 4.3.1.2 (coding
  indirect exits) in the CA MICS System Modification Guide.
  Contact the CA MICS Product Support Group if you need
  assistance in implementing this exit.

If you plan to install this product in an existing database
unit, follow the checklist in Section 3.8.2 of the PIOM.

If you plan to install this product in a new database unit,
follow the checklist in Section 3.8.3 of the PIOM.
