APAR Error Description / Circumvention

-----------------------------------------------
Application experiences long delays. SQL select statement that
normally take much less than 1 second suddenly start taking over
30 seconds, sometimes minutes. The times these delays occur
there appears to be locks.

CORRECTION FOR APAR SE73484 :
-----------------------------
Timestamp fields in formats require conversion at first touch in
7.2 .  The extract of format information is incorrectly
requiring an *EXCL lock to do this conversion. The code is
corrected to require an *SHRNUP lock.

CIRCUMVENTION FOR APAR SE73484 :
--------------------------------
None.


DESCRIPTION OF PROBLEM FIXED FOR APAR SE76462 :
-----------------------------------------------
A restore of a logical file fails with msgCPF3226 indicating a
field referenced in the logical file does not exist in the
physical file.

CORRECTION FOR APAR SE76462 :
-----------------------------
This problem can occur when restoring a file on a post-V4R3
release that was saved from a pre-V4R4 release. Restore
processing is referencing field information that did not exist
prior to V4R4. The restore code is corrected to no longer
reference this area in the field definitions for files created
prior to release V4R4.

CIRCUMVENTION FOR APAR SE76462 :
--------------------------------
None.


Activation Instructions
