Provide a Software to Hardware Recompression utility - OMCSS2HC

_PROBLEM DESCRIPTION:
Compressed database files that use the software compression algorithm
are more costly to decompress than those compressed using the optional
OMCS/MVS Hardware Compression Support (FMID ASEB201).

The repeated decompression of frequently accessed compressed files can
represent significant processor time over the life of the data.  Sites
that have ASEB201 installed may take retrospective advantage of hardware
compression by recompressing frequently accessed compressed files using
the utility program OMCSS2HC.

_PROBLEM SUMMARY:
USERS AFFECTED: Licensees of the OMCS/MVS Hardware Compression support
                FMID ASEB201.


_PROBLEM CONCLUSION
RECOMMENDATION: Apply PTF ASP0846

_OPERATIONAL NOTES:

See ASESAMP(RUNS2HC) for sample JCL to run the program.

Program OMCSS2HC can be run with more or less specific Filename and
Filetype (FN= FT=) arguments to inspect one or many files in a database
and to recompress from software to hardware format in place.  The
program can be safely run while other work proceeds.  Files that are not
compressed will be ignored.  Files with names that dont match the FN=
and FT= arguments will be ignored.

Users who attempt to read a file while it is being recompressed will
wait until recompression is complete for that file.  Similarly if a
user(s) has a file open at the time that OMCSS2HC attempts to recompress
it then OMCSS2HC will wait until the user(s) release the file.

The program lists files inspected and identifies those recompressed.

_NON-SMP/E SITES PLEASE NOTE:

1. Apply this fix using the ASMPMAIN program.  Refer to ASE Technical
   Bulletin TB90-0014 for sample JCL for running this program or see
   the .ASESAMP member called RUNASMP.

2. This fix contains ++SRCUPD statements.  After applying the fix you
   must recompile the ECL programs named in ++SRCUPD statements to
   create new load modules from them.  For sample JCL see the .ASESAMP
   member called RUNECLC which was distributed on PUT9112.
