APAR Error Description / Circumvention

-----------------------------------------------
An SQLRPGLE program accesses a view to read XML data fails.
When the job ends, dumps are created with the error message
MCH0601 f/QXLXPCPARS.

CORRECTION FOR APAR SE66751 :
-----------------------------
Memory used by XML_TABLE was missing at job termination.  Since
the job is going away, XML_TABLE has been updated to ignore
missing memory.

CIRCUMVENTION FOR APAR SE66751 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR SE66942 :
-----------------------------------------------
After loading the latest DB Group msgMCH6903 and msgMCH0601
started occurring in an application doing XML decomposition
after many iterations.

Errors returned listed below.

msgMCH6903 f/#hmalcmi t/QC2UTIL1

Message . . . . : The heap space has reached its maximum
allowable size.
Cause . . . . . : The heap space has reached its maximum
allowable size. The
heap space identifier is 0. The activation group mark is 2. The
activation group mark will be zero if the heap space is not
associated with an
activation group.

Cause . . . . . : A program tried to set a space pointer, tried
to use
storage outside a space, or tried to use an unallocated page in
teraspace.
The space class is X'07'

CORRECTION FOR APAR SE66942 :
-----------------------------
A recent performance improvement had the side effect of
increasing the amount of memory used by jobs using XML
decomposition.  XML decomposition has been corrected to reduce
much of his extra overhead.

CIRCUMVENTION FOR APAR SE66942 :
--------------------------------
None.

Special Instructions


********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI58336 :
=================================================

To properly enable this PTF for prestarted server jobs,
you will need to stop and restart the SQL server jobs,
the Directory Services server jobs, the DRDA TCPIP server
jobs, and the host server jobs.  Otherwise,
the prestarted server jobs may continue to use older versions
of programs and unexpected results may occur.Applying this
PTF as delayed would achieve the same results.

To stop and restart the SQL server jobs, run the following:

ENDPJ SBS(QSYSWRK) PGM(QSQSRVR) OPTION(*IMMED)
STRPJ SBS(QSYSWRK) PGM(QSQSRVR)

To stop and restart the QRWTSRVR prestart jobs, run the following:

ENDPJ SBS(QUSRWRK) PGM(QRWTSRVR) OPTION(*IMMED)
STRPJ SBS(QUSRWRK) PGM(QRWTSRVR)

To stop and restart the DRDA TCPIP server jobs, run the following:

ENDTCPSVR SERVER(*DDM) OPTION(*IMMED)
STRTCPSVR SERVER(*DDM)

To stop and restart the Directory Services server job,
run the following:

ENDTCPSVR SERVER(*DIRSRV) OPTION(*IMMED)
STRTCPSVR SERVER(*DIRSRV)

To stop and restart the host server jobs, the following directions
must be followed.

The database server prestart jobs (QZDAINIT, QZDASOINIT, and
QZDASSINIT) by default are shipped to run in subsystem QSERVER
(QZDAINIT) and QUSRWRK (QZDASOINIT and QZDASSINIT).  However, systems
can be customized to allow the database server prestart jobs to run
in other subsystems.

SYSTEMS WITH DEFAULT CONFIGURATION (database server prestart jobs run
ONLY in the QSERVER and QUSRWRK subsystems).
---------------------------------------------------------------------

1) To ensure that the database server prestart jobs are ended,
issue the requests:

QSYS/ENDPJ SBS(QSERVER) PGM(QSYS/QZDAINIT) OPTION(*IMMED)
and
QSYS/ENDPJ SBS(QUSRWRK) PGM(QSYS/QZDASOINIT) OPTION(*IMMED)
and
QSYS/ENDPJ SBS(QUSRWRK) PGM(QSYS/QZDASSINIT) OPTION(*IMMED)
and if a non default prestart job configuration exists
QSYS/STRPJ SBS("subsystem-name") PGM(QSYS/QZDAINIT)

If the above commands fail with CPF0922, nothing more needs
to be done (the prestarted jobs are already inactive).

2) To re-enable the function after the PTF is applied, issue the
requests:

QSYS/STRPJ SBS(QSERVER) PGM(QSYS/QZDAINIT)
and
QSYS/STRPJ SBS(QUSRWRK) PGM(QSYS/QZDASOINIT)
and
QSYS/STRPJ SBS(QUSRWRK) PGM(QSYS/QZDASSINIT)
and if a non default prestart job configuration exists
QSYS/STRPJ SBS("subsystem-name") PGM(QSYS/QZDASSINIT)

If the above commands fail with CPF0921, nothing more needs
to be done (the prestarted jobs are already active).


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
