Problem IC67407

Status: Geschlossen |
DB2DART FAILS TO IDENTIFY INITIALIZED BUT UNUSED EXTENT MAP PAGES THAT ARE CORRUPT |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 |
| Problembeschreibung: |
In a DMS tablespace, when a table is created, an entire extent
of Extent Map Pages (EMP) are initialized. Initially, only the
first page of this EMP extent is used. If an unused EMP page
becomes corrupted (due to hardware failure), then db2dart is not
able to idenitfy this corruption.
If this corrupt page is ever accessed, either as a result of
growing the table, reorganizing the table, or dropping the
table, then the database will crash with a bad page error. |
