Problem IC97084
|
Status: Closed |
UPGRADE DATABASE MAY TAKE LONG IN DPF ENVIRONMENT DUE TO DYNAMIC STATEMENT CACHE INVALIDATION |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
You may encounter long running database upgrade in DPF
environment.
During database upgrade a call to
SYSIBMINTERNAL.ADMIN_REFRESH_TBSP_ATTRIBS is made. This changes
the prefetch size for tablespaces.
As part of this operation DB2 invalidates the dynamic statement
cache on all DPF partitions. This may take very long.
A db2trc (perfcount) will show a lot of time spent in function
sqlrlInvalAPMCacheForTable. |
