I have a problem
my database is too slow and when i type TOP (under linux) i see a PID
after that i run a ps -ef|grep pid
oracle 24504 1 43 Jul 14 ? 58115:27 oracleEDUPROD (DESCRIPTION=(LOCAL=no)(ADDRESS=(PROTOCOL=BEQ)))

now my problem is how to see what is doing that session and after that
how to close that session?

yes but first i must to know what user is, and what is he doing
if he is using a sqlldr (as for example) maybe it is a long operation and i cant just kill it
maybe is an rman,

and at last, my idea is close that session using oracle not kill that operation.
Thnx for your quick reply Very Happy

Good luck. IIRC, joining V$SESSION with V$TRANSACTION will provide the SID of this rogue process.

I'm about 2,000 kilometers from my office & bandwidth limited now; so I can not assist in more detail.

GOOGLE is your friend but only when you actually USE it.
Results 1 - 10 of about 70,300 for unix pid oracle sid. (0.13 seconds)

Please show SOME initiative & stop depending upon being spoonfed.
