ABSTRACT OF PROBLEM
___________________
Recoup APAR PQ42097 has some problems: ZRECP STA results in a
wrong max chain count, QUE processing does not work properly,
some online messages are not output correctly, and ZRECP LOG is
not validated properly.
COMMENTS ON PROBLEM
___________________
1. The maximum chain count field in the recoup statistics
display may show an incorrect number of chains because a
register is not cleared before the value is set up.
2. TPFDF recoup QUE processing will not run correctly because
checks are performed using an incorrect DBDEF subtable base.
Furthermore, QUE processing requires specifying the MPPRCD=
and MPNXTD= parameters in the DBDEF, but this is not
enforced.
3. Some online output messages are not generated properly. The
output from a ZRECP REPORT command may be routed to the
wrong terminal address as EBROUT is set up as if the report
were being generated automatically instead of entered manu-
ally. In addition, the appended messages for system errors
OPR-141302 and OPR-141303 contain an invalid character
because the message length is not set up correctly. Also,
the SSU is not displayed properly on a RECP9012I online
message because it is not passed properly from segment BRC1
to segment BRCF. Furthermore, SNAPC error 41111 should have
a prefix of 'I' to indicate that it is an IBM system error.
4. The ZRECP LOG command is not always validated or processed
properly. There is an existing check for subsequent fixed
errors of one ID to avoid multiple fixed error messages in
the ZRECP LOG file. The check does not work correctly as it
does not set up the correct keypoint base. In addition,
input validation for ZRECP LOG is incomplete and might
result in wrong error messages or CTL-dumps. Furthermore,
the ZRECP LOG database has been defined to have only 30
ordinals per processor (partition). This might be too small
and will result in OPR-DB0102 system errors if more than 500
IDs are processed on 1 processor.
5. In addition, a CTL-3 or CTL-4 system error may occur when
aborting recoup because existing ECBs attempt to still use
the recoup keypoint when it is no longer valid.
6. Finally, assembler DSECT SRMP1A and C header file C$SRMP1A
do not match. As a result, attempting to use a macro label
set (MLS) display of this database with ZUDFM will show an
incorrect layout.
SOLUTION
________
1. Segment BRCG has been updated to clear the register when
processing the maximum chain counter.
2. Segment BRCX has been updated to load the correct subtable
pointers in several locations to allow QUE processing to
work properly. In addition, the DBDEF macro has been
updated to generate an MNOTE 8 if MPPRCD= and MPNXTD= are
not specified with QUE=.
3. Segment BRCB has been updated to not modify EBROUT if ZRECP
REPORT was specifically entered (calling segment is BRMK).
Segment BRC9 was updated with the correct message lengths
for recoup system errors. Segment BRC1 was updated to pass
the SSU to segment BRCF. Segment BRCX has been updated to
generate PREFIX=I for system error 41111.
4. Segment BRC2 has been updated to load the correct keypoint
base to be able to correctly check for multiple fixed
errors. Segment BRC0 has been updated with adjusted input
validation to cover more error situations. Also WTOPC is
used instead of FMSG for ZRECP LOG processing. Macro GR0ZSR
has been modified to use 120 ordinals per partition instead
of 30.
5. Segments BRC8 and BRCX have been updated with additional
checks for the correct keypoint base to avoid CTL-3 and
CTL-4 system errors.
6. Header file C$SRMP1A has been packed to match the SRMP1A
macro layout. Furthermore, TPFDF standards have been
applied to both segments and a standard length equate
(_SRMPL80) has been adjusted for use in segments BGA4 and
BGA7 to set up the LREC length.

Migration Considerations
========================
This APAR applies to TPF customers only.
- Any DBDEFs that specify QUE=YES without MPPRCD= and
MPNXTD= specified will have to be updated before they
are reassembled.
- To increase the number of ordinals for #GR0ZSR do the
following:
1. Generate and load the FACE table with 960 ordinals for
#GR0ZSR (8 partitions with 120 ordinals each).
2. Assemble and load UF1B
3. Enter ZUDFM DEF INIT
4. Enter ZUDFM INIT FDF4 (twice) to initialize the file.
This step will delete any previous recoup logs you may
have.
