I had the same occurance on an 8.0.5 database. We had a long job running , also a trucate, that was killed. When this happened the database core dumped and died. We looked it up on Metalink and found that it was a known error with that version of the database. It appears to happen with heavy IO intensive operations.
Its too bad you have the same error on 8.1.6. I hope its fixed in 8.1.7 because thats where we are heading to. -----Original Message----- Sent: Wednesday, January 30, 2002 9:11 AM To: Multiple recipients of list ORACLE-L Hi My instance was crashed when one of users was truncating the table.the following are the error message in alert log Wed Jan 30 00:15:13 2002 Errors in file pathname/udump/ora8_ora_9453.trc: ORA-07445: exception encountered: core dump [ksqcmi()+5792] [SIGSEGV] [Address not mapped to object] [0] [] [] ORA-01013: user requested cancel of current operation Wed Jan 30 00:15:19 2002 Errors in file path/bdump/ora8_pmon_4339.trc: ORA-00600: internal error code, arguments: [1100], [4162056452], [4162056452], [], [], [], [], [] Wed Jan 30 00:15:21 2002 PMON: terminating instance due to error 600 Instance terminated by PMON, pid = 4335 I checked metalink and found its a oracle bug.But this is happening first time.I have truncated so many tables but v=never faces such situation.During the instance crash the IOWAIT was high.THis is on oracle enterprise edition 8.1.6.0.0. on solaris 5.7 IS any one faced such situation .if yes then how come out from this situation.I don't want to upgrate 8.1.7 till now.
