I inherited support of an Oracle 9i dataguard backup system on Redhat Linux AS2 . However the standby database does not start up automatically on reboot. If the standby DB is down longer than the oldedst date of my saved arachives, I'm in big trouble. Can someone tell me how to setup the standby database to startup automatically? Setting oratab to Y does not work. Apparently I need to use the rc scripts to do this, but I don't know very much about them. I have found the file S99oracle ../init.d/oracle /etc/rc.d/rc3.d. I looked at it, and it's pretty detailed. If this is the correct file to modify could you point me in the right direction of what I need to do. I also read about a file called rc.local. Is this the file I need to start dataguard. Thank you very much in advance.
