APAR Error Description / Circumvention
-----------------------------------------------
Many concurrent identical optimizations compete for resources
which caused significant system performance problems.
CORRECTION FOR APAR MA43766 :
-----------------------------
The SQE optimizer will recognize when multiple identical
optimizations are required in the same time frame. When this
situation is identified, the optimizer will allow a subset of
optimizations to progress. Once the subset of optimizations
complete, the remaining optimizations attempt to match a plan
from the plan cache prior to continuing with the optimization.
CIRCUMVENTION FOR APAR MA43766 :
--------------------------------
None.
Activation Instructions
None.
Special Instructions
None.
Default Instructions
THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
