2.2 PSP Refresh Process and Checklists

The PSP refresh process uses a SAS "front end" that
eliminates errors and conserves DASD space during your PSP
library refresh.

Your complex's product change status table is queried for a
list of applied product changes.  This list is merged with
information supplied in the PSP distribution to determine
your complex's PSP level (the maintenance level of your
complex).  The PSP level is in turn used to identify the
members that will be copied from the distribution medium to
your PSP libraries.  If your complex has no maintenance left
to apply from the previous PSP, only the members required for
the most recent PSP will be loaded.

A Product Change Status Report is printed in the PSPRPT
SYSOUT data set. See Appendix B for an example of this
report.

Any interim PTF maintenance that has been applied will be
preserved in the sharedprefix.MICS.PSP.PC.TEXT library.  This
will accumulate over time.  Hence, the space and directory
block estimates for this library have been incremented to
allow for interim PTF maintenance.  Ensure that this library
has at least 40 free directory blocks before proceeding.

All partitioned PSP data sets are allocated with DISP=OLD and
their directories are reset.  The encrypted PSP file is
decrypted and the appropriate PSP DASD data sets are
refreshed.

Note that only the sharedprefix.MICS.PSP.PC.TEXT library is
preserved.  Consequently, any interim PTF maintenance added
to the PSP libraries will be lost.  If those PTFs have not
already been applied, it will be necessary to retrieve them
again from CA via Support Online after the PSP refresh.

To help conserve DASD space, a symbolic JCL parameter, RLS,
is used to release all unused space from each PSP data set
after it has been loaded by IEBCOPY.

The standard refresh process may be executed via MICF panels
or a manually submitted batch job.  See the sections below:
