啟動 / 停止 RAC 集群
確保是以 oracle UNIX 用戶登錄的。我們將從 rac1 節(jié)點運行所有命令：
- # su – oracle
- $ hostname
- Rac1
停止 Oracle RAC 10g 環(huán)境
第一步是停止 Oracle 實例。當(dāng)此實例(和相關(guān)服務(wù))關(guān)閉后，關(guān)閉 ASM 實例。最后，關(guān)閉節(jié)點應(yīng)用程序(虛擬 IP、GSD、TNS 監(jiān)聽器和 ONS)。
- $ export ORACLE_SID=orcl1
- $ emctl stop dbconsole
- $ srvctl stop instance -d orcl -i orcl1
- $ srvctl stop asm -n rac1
- $ srvctl stop nodeapps –n rac1
啟動 Oracle RAC 10g 環(huán)境
第一步是啟動節(jié)點應(yīng)用程序(虛擬 IP、GSD、TNS 監(jiān)聽器和 ONS)。當(dāng)成功啟動節(jié)點應(yīng)用程序后，啟動 ASM 實例。最后，啟動 Oracle 實例(和相關(guān)服務(wù))以及企業(yè)管理器數(shù)據(jù)庫控制臺。
- $ export ORACLE_SID=orcl1
- $ srvctl start nodeapps -n rac1
- $ srvctl start asm -n rac1
- $ srvctl start instance -d orcl -i orcl1
- $ emctl start dbconsole
使用 SRVCTL 啟動 / 停止所有實例
啟動 / 停止所有實例及其啟用的服務(wù)。我只是覺得有意思就把此步驟作為關(guān)閉所有實例的一種方法加進來了!
- $ srvctl start database -d orcl
- $ srvctl stop database -d orcl
啟停止監(jiān)聽
- hostb$lsnrctl start listener_hostb
- hostb$lsnrctl stop listener_hostb 備份 votning diskdd if =voting_disk_name f=backup_file_name dd if = /dev/ rdsk/c4t600C0FF000000000098ADE240330A000d0s4 f=votingdisk.bak # dd if=/dev/zero f=/dev/rdsk/c4t600C0FF000000000098ADE240330A000d0s4 bs=512 count=261120
