ora-3113 is a catch all error. There should be another error in the alert log when the client experiences the "end of file communication"? I saw this in 10.2.0.2, but I also got a ora-7445 exception encountered in the alert log. In my case it was a bug, it could be anything in your case. Probably related to not enough resources when doing something like sorting. Thats why when the query is changed, the resultset coming back may be different, and so it does not produce the same errors. Received on Tue Aug 05 2008 - 16:02:53 CDT
