Local-Fix: | |
1. Same as APAR IT16615, use a fixed value for sortheap, instead of letting STMM tuning it. Check db2diag.log for sortheap tuning entries and choose a value at the upper end in order to avoid having too low sortheap memory. 2.Set the problem query degree to 1 using optimizer guideline: There may be performance impact for this query since setting degree to 1 is taking away the performance advantage of SMP. | |
