I am pretty new to OAS.
We have an OAS server - 10.1.3.1
It was reported that the OAS was down.
$ opmnctl status
Unable to connect to opmn.
Opmn may not be up.
Sopmnctl startall - After starting it is working fine.
But, I want to do RCA, what made this OAS to go down. Which are the log files i need to see for this ?
