I have a question to ask, every time if node is rebooted, does database restart after it comes back? I mean, by default does it suppose to restart, or user has to manually bring it up? In my case, I noticed whenever I reboot my node, database never starts after that, and instead all vprocs go to FATAL state. What is the reason for that?
No, it's not a demo system, it is a testing system and reboots are more often than in production environment. I have read stopping and restarting the system, and by default the database should start. However sometimes after reboot I get fatal vprocs. That is definitely not expected. So, checking messages did not throw more light in this problem, but next time I see this issue again I will paste the messages output here. Thanks so much for your help.
