SYMPTOM(s):
SYSTEM ERROR: Unexpected extent switch note (766)
Database cannot start up
After imaging is enabled
CAUSE:
The before-image area contains a note to perform an unexpected after-imaging extent switch operation.
The exact circumstances leading to this issue are not known, however the issue is known to happen more likely in the following situations:
- when after-image extent switch (aimage new) operations are run at close time intervals, e.g. less than 1 minute apart,
- when AI extent switch are happening simultaneously to a BI cluster switch operation, or
- when AI extent switch is happening during an offline backup.
FIX:
To resume normal operation on the database it is necessary to ignore this note during the redo/undo phase of database startup or truncate BI operation. For this purpose the recommended way is to reset after-imaging:
rfutil <db> -C aimage end
proutil <db> -C mark backedup
rfutil <db> -C aimage begin
proutil <db> -C truncate bi
