APAR Error Description / Circumvention
-----------------------------------------------
MySQL or other QmyProcessRequest API client programs using
multiple connections may encounter 2021 errors and MCH3402
messages to/from QMYSE when performing an API operation. This is
most likely to happen under heavy load, when multiple new
connections are being established simultaneously.
CORRECTION FOR APAR SE55270 :
-----------------------------
When multiple connections are simultaneously established,
internal structures used to associate QSQSRVR jobs may be
incorrectly updated. This may lead to a variety of error
conditions including query failures with MCH3402 messages and
extraneous QSQSRVR jobs. This fix corrects how the internal
structure is maintained. After the application of this PTF MySQL
or other QmyProcessRequest API client programs will need to be
restarted.
