POSSIBLE DATA LOSS WHEN CALLING ADMIN_MOVE_TABLE AND TRIGGERS ARE MISSING PRIOR TO THE SWAP PHASE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
During the INIT phase of ADMIN_MOVE_TABLE a number of triggers
are created to capture any data changes made to the source
table. If any of these triggers are dropped prior to the SWAP
phase, it is possible to miss some changes that happened to the
source table during the move, and have data loss after the move
completes. |

| Local-Fix: |
Before the SWAP phase, make sure the triggers still exist. This
can be done by checking SYSCAT.TRIGGERS. For the table being
moved, there should exist 4 triggers, with a name similar to
'T1AAAAVxi', where T1 is the name of the table being moved. If
these 4 triggers don't exist, cancel the move operation and
start it again. |
