Problem IT09392
|
Status: Closed |
DB2 MAY CRASH WHEN REPLAYING FEDERATED XA LOG RECORDS IF FEDERATED TWO_PHASE COMMIT IS USED |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
DB2 may crash when trying to replay
federated XA log records produced on earlier fixpacks
The stack seen will be:
memcpy
sqlqgRFwdFedPrep
sqlpRecDbRedo
...
Situations where this could arise would include explicit
rollforward after a restore or when performing a rolling upgrade
of an HADR pair.
When upgrading to a new fixpak or when rolling fixpak back,
please, avoid using federated XA log records produced on a
different fixpak.
If this is unavoidable, please, request Special Build from DB2
Support to replay old logs.
After the issue is resolved, please, un-install Special Build
and take a new backup to avoid any need to replay problematic
log records again. |
