Ora-600 is Oracle's implementation of "WHEN OTHERS" exception ... But implemented very cleverly I must admit. Not all ORA-600 have events associated with them. There is only one event that should fire on ORA-600 and it is invoked as follows ... Alter dba set events "call oracle support context immediate, level itar' / Seriously calling OWS is the best approach, using certain events and setting without prior approval of OWS means you are out of luck on support issues.=20 Raj ------------------------------------------------------------------------ --------=20 Rajendra dot Jamadagni at nospamespn dot com=20 All Views expressed in this email are strictly personal.=20 select standard_disclaimer from company_requirements;=20 QOTD: Any clod can have facts, having an opinion is an art ! -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of ryan.gaffuri@xxxxxxx Sent: Wednesday, May 19, 2004 11:21 AM To: oracle-l@xxxxxxxxxxxxx Subject: extended sql tracing for diagnosing ora-600 errors Aren't there a few events that are useful to provide information when you get database errors?
