Status: Closed |
UNNECESSARY PACKED DESCRIPTOR UPDATES DURING ALTER TABLESPACE STATEMENT |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
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. |
