APAR Error Description / Circumvention

-----------------------------------------------
An SQL ALTER TABLE operation fails when the secondary node gets
set to BLOCKED in the middle of the operation. The ROLLBACK
operation appears to fail to clean up the request on the
secondary properly.

CORRECTION FOR APAR SE72470 :
-----------------------------
The Db2 Mirror engine is failing to properly identify and signal
the CPFC901 message that indicates the object is BLOCKED. The
failure to issue this message results in the ROLLBACK operation
failing to rollback and clean up the operation properly.

A PTF will be provided to signal the CPFC901 message properly in
this scenario when the node has been BLOCKED.

CIRCUMVENTION FOR APAR SE72470 :
--------------------------------
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THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED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SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI71039 :
=================================================

To activate this fix, the Db2 Mirror QMRDBECTLR job must be restarted.

If this PTF is applied or removed as a delayed PTF, which requires
an IPL, then no special consideration is necessary.

If this PTF is applied or removed as an immediate PTF, then:
1. Db2 Mirror replication must be suspended for maintenance using
the Db2 Mirror GUI or by using the QSYS2.CHANGE_MIRROR procedure:
CALL QSYS2.CHANGE_MIRROR(REPLICATION_STATE => 'MAINTENANCE');

2. Apply this fix if not already applied.

3. Resume Db2 Mirror replication using the Db2 Mirror GUI or by
using the QSYS2.CHANGE_MIRROR procedure:
CALL QSYS2.CHANGE_MIRROR(REPLICATION_STATE => 'RESUME');


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
