APAR Error Description / Circumvention
-----------------------------------------------
The query optimizer tries to prevent itself from using too many
resources when many jobs submit the same complex query
simultaneously. Rather than separately optimizing each one,
only a few concurrent optimizations are allowed, while the other
jobs will wait on those results and potentially re-use the
plans.
If something fails in this gating code, this support is
automatically disabled, which can lead to problems on busy
systems with very complex queries.
CORRECTION FOR APAR MA47450 :
-----------------------------
If the concurrent optimization support is disabled for some
reason (unexpected failure), the optimizer will attempt to
re-start it automatically after the problematic job(s) complete.
CIRCUMVENTION FOR APAR MA47450 :
--------------------------------
None.
Activation Instructions
None.
Special Instructions
None.
