DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problembeschreibung: |
Problem description
When multiple members are requesting the same lock in a
pureScale cluster and the lock notification to reclaim is lost
then an application hang may occur and possibly an entire
database hang depending on the current locks held by the
application in a hang state.
A missing lock notification can be triggered during cable pull
when an adapter goes down,
or a lock notification timeout where the following error is
logged:
