3 Oracle啟動方式有哪幾種?
nomount:
startup nomount srvctl start database -db db_unique_name nomount srvctl start instance instance_name -d dbname -o nomount
mount:
startup mount alter database mount; srvctl start instance instance_name -d dbname -o mount
open:
startup open alter database open; srvctl start instance instance_name -d dbname -o open srvctl start instance instance_name -d dbname -o open
other:
startup restrict startup EXCLUSIVE startup read only alter database open noresetlogs; alter database open resetlogs; alter database open READ ONLY; startup force(shutdown abort + startup)
接引數檔案:
startup pfile='/oracle/dbs/initcjc.ora' startup spfile='/oracle/dbs/spfilecjc.ora' srvctl modify database -db db_unique_name -spfile spfile_path
4 Oracle無法啟動問題彙總
(1)引數檔案損壞故障分析 (2)控制檔案損壞故障分析 (3)資料檔案損壞故障分析 (4)UNDO檔案損壞故障分析 (5)REDO檔案損壞故障分析 (6)壞塊故障分析 (7)勒索病毒故障分析 (8)更新補丁後資料庫異常故障分析 (9)人為誤操作故障分析 具體詳細內容見下一篇。
5 Oracle無法啟動問題定位
(1)啟動時檢視告警日誌 (2)確認啟動到哪一步報錯的 可以將startup命令拆開執行 startup nomount alter database mount; alter database open; 具體詳細內容見下一篇。
