Local-Fix: | |
Use optimizer guidelines to choose a join method other than hash join, or use query optimization class 3 not to pick up hash join. However, note that completely avoiding hash join in the entire instance could cause a severe performance degradation. | |
Lösung | |
This problem was first fixed in DB2 V10.5 FixPack 7. | |
