Updates or deletes that empty at least a full extent in the table 2. Reorganization of the table using the RECLAIM EXTENTS option (this is automatically done for column organized tables when DB2_WORKLOAD=ANALYTICS is set and the database config parameters auto_maint and auto_table_maint are set to ON) 3. A statement on the affected table that attempts to scan a portion of the table that has been reclaimed Recommended Actions: Contact DB2 Support if you encounter this issue | |
