CAUSE JUSTIFICATION =================== ---- Customer's errors in alert log and trace file match with this issue. --- Customer's call stack trace in the trace file match with this issue. The cause can be justified by the followings: Bug 2028564 Abstract: DATABASE CRASHED WITH ORA-600 [1115] BECAUSE PMON FAILED TO CLEANUP SESSION. Note 2028564.8 Bug 2028564 - ORA-7445 or OERI 17114 errors possible after OERI:729 - PMON may die PROPOSED SOLUTION(S) ==================== 1. Apply one-off patch for Bug 2028564 according to your OS platform and version. OR 2. Upgrade to 9.2.0.4 or later version...for example 9.2.0.8. PROPOSED SOLUTION JUSTIFICATION(S) ================================== 1. One-off patch for Bug 2760836 has fixed this issue...so after customer apply the one-off patch...then this issue will be solved. OR 2. 9.2.0.4 or later version has fixed this issue...so after customer upgrade to at least 9.2.0.4 version...then this issue will be solved. The solution can be justified by the followings: Note 2760836.8 PMON cleanup of dead shared servers/dispatchers can crash instance (OERI 26599 / OERI 1115)
