Symptom
- The errorlog shows only 1 log record for the REDO pass, but still takes considerable time to recover; times observed can be 10s of minutes or even hours depending on database size
- In the errorlog, there is a time gap between the REDO pass and the timestamp messages
- Online database (very) slow
- Recovery of a very large database with mix data and log takes hours
- Here is an example from the error log:
00:01:00000:00001:2013/08/09 14:55:12.46 server Started REDO pass for database 'database_name'. The total number of log records to process is 1.
00:01:00000:00001:2013/08/09 14:55:12.47 server Completed REDO pass for database 'database_name'.
00:00:00000:00001:2013/08/09 15:06:10.06 server Timestamp for database 'database_name' is (0xc17b, 0x31f7b353). ---> 10 mins gap
00:00:00000:00001:2013/08/09 15:06:10.06 server Recovery of database 'database_name' will undo incomplete nested top actions.
