Better not. ANONYMOUS is used by XDB sessions, such as APEX users coming in through the embedded PL/SQL gateway.

No. Username of NULL is very likely to be an Oracle process. What do you get if you add PROGRAM and MACHINE to your query? i.e.

SELECT username, status, sid, serial#, program, machine
FROM v$session;

Also, please use code tags to format your output.

How many cpus?

What packs do you have?

Edit: wait 65.4%sy is bad news. Is the host properly configured?

Also post select count(*) from v$process

select status,count(*) from v$session group by status

Is host dedicated?
Is AMM in use?
What clues exist in the alert log?
What is db_cache_size?

You're running an unsupported base release, 10.2.0.1. ORA-07445 usually requires opening a SR with Oracle but I suspect they'll want you to upgrade to a supported version. In the meantime, is there a possibility of restarting the database server?

Can't raise a TAR. Oracle doesn't support XE, or installations on EC2, or installations on Ubuntu. Only option would be upgrade to 11.2 XE. And in the meantime, make your online logfiles ten times as big. Which might take a big strain off the OS.

Then restart for now and get clearance from management to upgrade. A supported O/S might be in order too. Perhaps Oracle Linux.

Hi,

I search for ORA-07445 http://www.oracle.com/technetwork/issue-archive/2011/11-sep/o51support-453463.html
I think this oracle or Linux is bad configured
