  啟動和停止集群

  以下操作需用root用戶執行

  ()在本地服務器上停止Oracle Clusterware 系統

  [root@rac ~]# /u/app//grid/bin/crsctl stop cluster

  CRS: Attempting to stop oracrsd on rac

  CRS: Starting shutdown of Cluster Ready Servicesmanaged resources on rac

  CRS: Attempting to stop oraLISTENERlsnr on rac

  CRS: Attempting to stop oraCRSdg on rac

  CRS: Attempting to stop oraracdbdb on rac

  CRS: Attempting to stop oraregistryacfs on rac

  CRS: Stop of oraLISTENERlsnr on rac succeeded

  CRS: Attempting to stop oraracvip on rac

  CRS: Stop of oraracvip on rac succeeded

  CRS: Attempting to start oraracvip on rac

  CRS: Stop of oraregistryacfs on rac succeeded

  CRS: Start of oraracvip on rac succeeded

  CRS: Stop of oraCRSdg on rac succeeded

  CRS: Stop of oracssdmonitor on rac succeeded

  CRS: Stop of oraevmd on rac succeeded

  CRS: Stop of oractssd on rac succeeded

  CRS: Stop of oraasm on rac succeeded

  CRS: Attempting to stop oracssd on rac

  CRS: Stop of oracssd on rac succeeded

  CRS: Attempting to stop oradiskmon on rac

  CRS: Stop of oradiskmon on rac succeeded

  注在運行crsctl stop cluster命令之後如果 Oracle Clusterware 管理的資源中有任何一個還在運行則整個命令失敗使用 f 選項無條件地停止所有資源並停止 Oracle Clusterware 系統

  另請注意可通過指定 all 選項在集群中所有服務器上停止 Oracle Clusterware 系統如下所示在rac和rac上停止oracle clusterware系統

  [root@rac ~]# /u/app//grid/bin/crsctl stop cluster –all

  在本地服務器上啟動oralce clusterware系統

  [root@rac ~]# /u/app//grid/bin/crsctl start cluster

  注可通過指定 all 選項在集群中所有服務器上啟動 Oracle Clusterware 系統

  [root@rac ~]# /u/app//grid/bin/crsctl start cluster –all

  還可以通過列出服務器(各服務器之間以空格分隔)在集群中一個或多個指定的服務器上啟動 Oracle Clusterware 系統

  [root@rac ~]# /u/app//grid/bin/crsctl start cluster n rac rac

  使用 SRVCTL 啟動/停止所有實例:

  [oracle@rac ~]#srvctl stop database d racdb

  [oracle@rac ~]#srvctl start database d racdb

  安裝的後置任務

  .官方建議的兩個安裝後置任務

  () 備份 rootsh 腳本

  官方建議在完成安裝後要備份rootsh腳本文件如果在Oracle Home目錄中又安裝其它的產品安裝時OUI會升級已存在的rootsh文件如果需要rootsh內的原始信息就可以在備份中找到

  cd $ORACLE_HOME;cp rootsh rootshbak

  ()重新編譯無效對象

  運行 utlrpsql 腳本立即重新編譯所有無效的 PL/SQL 程序包而不是在首次訪問它們時再重新編譯這是個可選步驟但建議您選擇該步驟

  [oracle@racnode ~]$ sqlplus / as sysdba

  SQL&gt; @?/rdbms/admin/utlrpsql

  在 RAC 環境中啟用存檔日志

  ()以 oracle 用戶身份登錄到一個節點(即 racnode通過在當前實例中將 cluster_database 設置為 FALSE 來禁用集群實例參數

  [oracle@rac ~]$ sqlplus / as sysdba

  SQL&gt; alter system set cluster_database=false scope=spfile sid=racdb;

  System altered

  ()以 oracle 用戶身份關閉所有 訪問集群化數據庫的實例

  [oracle@rac ~]$ srvctl stop database d racdb

  ()使用本地實例掛載數據庫

  [oracle@rac ~]$ sqlplus / as sysdba

  SQL*Plus: Release Production on Sat Nov :: Copyright (c) Oracle All rights reserved Connected to an idle instance

  SQL&gt; startup mount

  ORACLE instance started

  Total System Global Area bytes

  Fixed Size bytes

  Variable Size bytes

  Database Buffers bytes

  Redo Buffers bytes

  ()啟用存檔功能

  SQL&gt; alter database archivelog;

  Database altered

  ()通過在當前實例中將實例參數 cluster_database 修改為 TRUE重新啟用對集群的支持

  SQL&gt; alter system set cluster_database=true scope=spfile sid=racdb;

  System altered

  ()關閉本地實例

  SQL&gt; shutdown immediate

  ORA: database not open

  Database dismounted

  ORACLE instance shut down

  ()以 oracle 帳戶身份使用 srvctl 命令重啟所有實例

  [oracle@rac ~]$ srvctl start database d racdb

  ()登錄到本地實例驗證存檔日志模式已啟用

  [oracle@rac ~]$ sqlplus / as sysdba

  SQL*Plus: Release Production on Sat Nov :: Copyright (c) Oracle All rights reserved Connected to: Oracle Database g Enterprise Edition Release bit Production With the Partitioning Real Application Clusters Automatic Storage Management OLAP Data Mining and Real Application Testing options

  SQL&gt; archive log list

  Database log mode Archive Mode

  Automatic archival Enabled

  Archive destination USE_DB_RECOVERY_FILE_DEST

  Oldest online log sequence

  Next log sequence to archive

  Current log sequence

  在兩個RAC節點都備份spfile初始化參數文件:創建一個備份目錄

  [oracle@rac ~]$ mkdir $ORACLE_HOME/spfile_bak

  [oracle@rac ~]$ sqlplus /as sysdba
