Hi,

This Morning:

I have a server with 3 instances running(I can access all instances).

This Afternoon:

Tried to create a new instance but get the Oracle not available error.
UNIX admin jacks up max number of processes and users, I can then create new instance.

When doing a shutdown/startup, one of the instances I was able to access in the morning did not start. Tried to start manually but get

ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

What other parameters should I be looking at on the UNIX side?

BTW...Connecting as internal and issuing a startup command gives me a

SQL> startup
ORA-24323: value not allowed
ORA-03113: end-of-file on communication channel

error.

Can anybody help?

Thanks
