Oracle 11gR2 New Features Oracle Restart

      oracle 11gR2 單機如果要安裝asm儲存的資料庫,需要先安裝grid元件,透過ocssd程式與asm例項進行通訊

   在安裝的四個選項,選擇第二個：

即installation option

Install and Configure Grid infrastructure for a standalone server

按下一步安裝建立asm instance 和 asm diskgroup 和 監聽

最後按提示執行root.sh 指令碼即可，可以用crsctl status res -t 命令檢視元件的狀態

安裝完grid後的狀態如下：

[grid@zjzxdb1:/grid/app]$crsctl status res -t

即Oracle 11gR2 New Features Oracle Restart

Oracle Restart improves the availability of your single-instance Oracle database. Oracle Restart automatically restarts the database instance, the Automatic Storage Management (ASM) instance, the listener, and other components after a hardware or software failure or whenever your database host computer restarts. Server Control (SRVCTL) is the command line interface to manage Oracle processes that are managed by Oracle Restart on a standalone server.
