Hi Guys'I have this error message from the alert log and don't know how to go about it. Can someone please help?
This process termination request for PID indicates that this process has received SIGTERM signal and is going to exit.
Generally, the cause of this message is because the database server or the Clusterware decided to terminate the process, in which case the message will show "source = rdbms" or "source =clusterware".
When the message shows "source = unknown" it indicates that the signal is from an unexpected external source, for example, "kill" command from the shell or a monitoring tool that may throw SIGTERM signal to oracle processes.
If database processes are being killed with messages like the above in the alert log, it is being killed by external command or tools.
