APAR Error Description / Circumvention
-----------------------------------------------
Large nodal systems that are executing database updates at a
very high frequency could experience high cacheline contention,
potentially reducing system performance.
CORRECTION FOR APAR MA47497 :
-----------------------------
The code was modified to reduce the cacheline update frequency.
CIRCUMVENTION FOR APAR MA47497 :
--------------------------------
None.
Activation Instructions
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THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED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SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF61047 :
=================================================
If one or both of the PTFs for MA45275 or MA45104 have been installed
on a system when a table or physical file is saved, then BOTH of those
PTFs must also be installed on the system where the file is restored to
prevent the possibility of a restore failure. Specifically, some files
with variable length or LOB fields may be damaged during the restore if
the PTFs are not present. Because this may occur when restoring across
releases, PTFs for all releases are listed.
NOTE: One or both of the PTFs for MA45275 and MA45104 may be installed
on the restore system when a table or physical file is restored even if
the PTFs were not installed on the save system at the time of the save.
This includes saving a file from a system at one release and restoring
it to a system at a different release.
The PTFs for MA45275 are:
V7R1: MF62518
V7R2: MF62519
V7R3: MF61374
The PTFs for MA45104 are:
V7R1: MF61046
V7R2: MF61047
V7R3: MF60986
Default Instructions
THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
