You have either not logged in or something closed your connection.

What application/program/??? is generating that error?

Is the databsae started and 'open'?

from the sqlplus prompt type: startup

If it says it is already started try: alter database open;

I've seen a few posts on other sites that indicate this can also be caused by exceeding the number fo processes.

check the processes spfile parameter.  You might need to increase the value:

Did I ask you to shutdown?  Why did you attempt to shut down in the first place?

Also, you should never use ABORT unless there is absolutely no other way to shut down.

>>and after kiiling some of the processes

This is worse that a shutdown abort.


To get back, might was well abort again:
shutdown abort;

Then from the OS kill any remaining oracle processes.

Then try to startup.
