UNNECESSARY PACKED DESCRIPTOR UPDATES DURING ALTER TABLESPACE STATEMENT | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 | |
Problembeschreibung: | |
Alter tablespace statements can lead to unnecessary packed descriptor updates for tables that reside in the affected tablespace. This can lead to unnecessary delays, or unexpected locking problems. The fix for this apar will ensure that the table packed descriptor is only updated if really needed e.g. when there is a change in transferrate, overhead, or prefetchsize. | |
