Re: why oracle processes spawn too much
Hi,
I could be wrong here, but are you looking at the right parameters ? I would say you're running into either the "maxfiles" or the "nfile" parameter.
Hope this helps,

Re: why oracle processes spawn too much
Hello,
this is usally a problem of a misconfigured application. It is not waiting long enough if a connect is not successfull.
An attempt to connect leads to an oracle seesion/process being created. Now the connect fails, and it takes some time to remove the session. If during this period a new attempt to connect comes in, you might eat up oracle resourses faster than they are freed again.
This may esp. occur, if you fire some testtool to a webapplication, that creates a lot of new db-sessions at once.
Would be of interest, why the first connect did not succeed and initiated this loop. If this is just a single event, you might be fine to increase processes/session by ten, to give more spare resources for single peaks, but if it is the "testtool" situation, it might no be sufficiant.
Do not know if this helps.
