APAR Error Description / Circumvention

-------------------------------------------------
In the Db2 Mirror environment, the REPLICATION_DETAIL column, as
returned by the QSYS2.MIRROR_INFO SQL view, may be SUSPENDING
for *SYSBAS on one node while the REPLICATION_DETAIL column is
SUSPENDED for *SYSBAS on the other node.  This can affect
overall processing giving the appearance of a hung system on the
node where the REPLICATION_DETAIL column is SUSPENDING.

CORRECTION FOR APAR 'SE71963' :
-------------------------------
Processing within the QMRDBECTLR job is updated to correct
handling of messages sent between the nodes during initial
suspend processing.

A PTF will be created to correct the problem. For a complete
fix, the PTF should be loaded and applied to both nodes of the
Db2 Mirror pair. It is not necessary to apply the fix to both
nodes of the pair at the same time, but the problem could occur
on a node that does not have the fix applied.

CIRCUMVENTION FOR APAR 'SE71963' :
----------------------------------
None.


Activation Instructions

None.




Special Instructions


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.
