Hi,
Sometimes you can get ” ORA-00470: LGWR process terminated with error ” error.
Details of error are as follows.
ORA-00470: LGWR process terminated with error
Error: ORA 470 Text: LGWR process terminated with error ------------------------------------------------------------------------------- Cause: The log writer process terminated abnormally. Action: Check the accompanying messages, if any, and the background process trace file. Correct the problem mentioned in the other messages. Then shut down and restart the instance. If the trace file mentions any other background process errors, check the trace file for the mentioned process until the root error is found
This is usually caused as LGWR process abnormally at OS level and the LGWR traces are blank.
Since the LGWR is one of the background processes, where the instance can not function properly without, ora-470 will lead to instance termination/crash.
The latest solution is startup or restart instance again.
