AIX不完整的補丁安裝以及Oracle的Bug

　　今天遇到一個AIX系統BUGOracle數據庫無法啟動甚至無法Nomount實例在Nomount之後馬上Crash
報告的錯誤是PMON無法啟動
告警日志信息摘錄

PMON started with pid= OS id=
Sun Dec ::
Errors in file /oracle/admin/oinst/bdump/oinst_pmon_trc:
ORA: exception encountered: core dump [] [] [] [] [] []

CJQ started with pid= OS id=
MMON started with pid= OS id=
MMNL started with pid= OS id=
Sun Dec ::
PSP: terminating instance due to error
Instance terminated by PSP pid =

　　最後確定疑似Oracle的一個BugBUG Number
對於這個BUGOracle建議的修正是Apply ML to AIX

　　而客戶的系統目前看來ML的安裝是不完全的

　　instfix i|grep ML
All filesets for _AIX_ML were found
All filesets for _AIX_ML were found
All filesets for _AIX_ML were found
All filesets for _AIX_ML were found
All filesets for _AIX_ML were found
All filesets for _AIX_ML were found
Not all filesets for _AIX_ML were found

　　不完全的補丁安裝是危險的在進行系統升級時一定要慎重最好將系統運行在經過驗證的穩定的系統版本上升級過快可能會帶來更多的不穩定因素
