I installed Oracle 8i on Solaris, and had my database up and running. someone shut down the box, and my db has crashed. I can't seem to get it started up again. when I try to log into the db using sqlplus, I get the error message ORA-1034 ORACLE NOT AVAILABLE. I've run the tnslsnr binary, and the oracle binary, but still no luck. any ideas? is there something, that I'm overlooking?
