ORA-01034 and ORA-27101 in server running fine

Hi all!

I've got a Oracle server working fine on an AIX computer. A homemade monitor monitorice each 5 minutes the connection and the problem becames when some queries are executed. Sometimes these queries make FULL SCAN ACCESS to some tables. This is crap, but the questions that are punhing my brain are:

• Why the OS is working fine? sometimes 50% CPU usage & 50% memory...
• Why Oracle server doesn't trace any alarm...
• Active sessions are 2 or 3 at a time...

But the monitor and other users trying to connect get this error: ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist IBM AIX RISC System/6000 Error: 2: No such file or directory

Maybe a problem with the listener??

Thanks for your help, guys!
