Problem IC69438
|
Status: Closed |
"DB2 LIST UTILITIES SHOW DETAIL" DISPLAYS WRONG ESTIMATE OF "TOT AL WORK" DURING BACKUP, WHEN TABLE AND INDEX COMPRESSION IS USED |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
The problem manifests itself only on the DMS tablespaces with a
high High Water Mark value , but a low "usedPages" value.
Under such circumstances the performance monitor sees a spike at
the moment when the backup process is completing reading a DMS
tablespace.
Therefore "db2 list utilities show detail" tends to display a
wrong estimate of "Total Work" during backup, in cases where
table and index compression is done. |
