Escalate the TAR. Call and ask for a duty manager if you can't get any help! Ruth -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of oracle@xxxxxxxxxxxx Sent: Wednesday, August 31, 2005 10:53 AM To: Oracle-L Subject: ORA-00600: internal error code, arguments: [17175], [255], [], [], [], [], [], [] (this time with message body!) I got hit with one of these yesterday and am still dealing with managerial fallout... ORA-00600: internal error code, arguments: [17175], [255], [], [], [], [], [], [] I reviewed the ora-600 lookup on Metalink but got scant information that is not very useful. It infers latch contention, etc. But is there another note or other information to give me a good explanation what caused this to happen? I have opened a tar but it's at severity 3 and I probably won't get an answer for a few more days. Thanks -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
