Linux Error: 11: Resource temporarily unavailable
I am getting this error for last 2-3 days. I need to start up the database manually.
Daily there is crontab schedule which will take the cold backup and startup the database. When I am checking daily morning. DBt is going into MOUNT stage instead of OPEN stage. I have check the script every thing is fine.
Note: This is happening intermetendly. Also is error is happening with different datafiles each time.
