I am experiencing a weird issue with Oracle where the service started fine after a crash. The database mount went fine as well. However, when I issue alter database open; command, the database does not open, gives a generic cannot connect to the database error & crashes the service.

Oracle support has not seen this issue before so it's pretty scary. The fact that there are no logs that give any leads as to what could be causing this is also scary.

I was wondering if good folks over at Server Fault had seen something like this or have some insights on things that I could try.

It's Oracle 10g running on Windows Server 2003.

Thanks,

Ashish
