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THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED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SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF52126 :
=================================================

APAR MA40422's PTF corrects an internal database index processing
problem during an Alter Table.  Without the PTF, a system crash after
the Alter Table exposes certain indexes to possible damage or
incomplete recovery.

Only a very small subset of indexes have the potential exposure to this
damage.
An index could become damaged during the system crash if:
- Main storage was not preserved at the time of the system crash
- The index's physical file was in use for update, insert, or delete at
the time of the system crash
- The index was explicitly journaled at the time of the crash (via the
STRJRNAP CL command)
- The index's physical file was altered at some point subsequent to
starting explicit access path journaling.
The alter of the physical file was performed in one of the following
three ways:
1) The SQL ALTER TABLE statement was performed
2) The CHGPF CL command with a SRCFILE keyword, or
3) An SQL DELETE statement without a WHERE clause (where all rows were
deleted) under commitment control)
- The index has not been rebuilt since the system crash

If you suspect you may have indexes that meet this criteria, you should
consider rebuilding these indexes or checking to ensure that the
indexes are not damaged.

To determine which indexes are currently explicitly journaled, you can
issue the following command:
DSPFD FILE(*ALL/*ALL) TYPE(*ACCPTH) OUTPUT(*OUTFILE) OUTFILE(QTEMP/A)

Then query the resulting table. For example, via the following SQL
statement:
SELECT * FROM qtemp.a WHERE APACPJ = 'Y'

To check indexes and ensure that the indexes are not damaged, the check
index tool can be used.  It is documented at
http://www-912.ibm.com/s_dir/slkbase.NSF/DocNumber/585335019.
