APAR Error Description / Circumvention

-----------------------------------------------
In some cases, when an IASP vary off is issued in a Db2 Mirrored
environment, there may be a small delay due to Db2 Mirror
related jobs finishing out work.

CORRECTION FOR APAR SE73031 :
-----------------------------
Operating system IASP vary off code was changed to inform Db2
Mirror jobs earlier that a vary off is occurring so that they
are able to end their processing sooner, thus mitigating the
delay.

CIRCUMVENTION FOR APAR SE73031 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR SE73032 :
-----------------------------------------------
In a Db2 Mirrored environment, when opening a database file or
querying the RCL for an IASP, the Operating System obtains an
implicit lock.
This lock is held for performance reasons and cannot be released
by the user.

CORRECTION FOR APAR SE73032 :
-----------------------------
Operating system code has been modified so that when the job
performs a SETASPGRP *NONE, this implicit lock is released.

CIRCUMVENTION FOR APAR SE73032 :
--------------------------------
None.
