RE: RE: what causes a memory dump?
Cary - Love the succinct reply! Ryan - Just create a daemon process that will remove any dump files every 3 seconds. Not to worry. Just kidding.

Ryan - The largest I've seen is 4-meg., so this is unusual. My suggestion would be to change your USER_DUMP_DEST to a drive with more free space, because the DBA's rule of life is that if an error is encountered once, it will probably be encountered again. Also check your alert log, because the error that caused the dump will be mentioned there. Try to diagnose the problem before it whacks you again. Good luck.

What about core dump? goes to cdump and that is the nastiest one occupying a lot of disk space. Only solution to define it not more than 5M (if i remenber correctly 10240 blocks).
