1.查看数据库所有实例与状态
unixdev$[/home/grid]srvctl status database -d unixdev Instance unixdev11 is running on node unixdev Instance unixdev12 is running on node unixtest
*注：在oracle或grid下执行均可
2.在特定节点上查看节点应用的状态，可以看到：VIP、NETWORK、GSD、ONS的状态
unixdev$[/home/oracle]srvctl status nodeapps -n unixdev VIP unixdev-vip is enabled VIP unixdev-vip is running on node: unixdev Network is enabled Network is running on node: unixdev GSD is disabled GSD is not running on node: unixdev ONS is enabled ONS daemon is running on node: unixdev
3.查看ASM实例状态
unixdev$[/home/grid]srvctl status asm -n unixdev ASM is running on unixdev unixdev$[/home/grid]srvctl status asm -n unixtest ASM is running on unixtest
3.1查看ASM实例配置信息
unixdev$[/home/grid]srvctl status asm #查看asm运行在哪些服务器上 ASM is running on unixdev,unixtest unixdev$[/home/grid]srvctl config asm -n unixdev Warning:-n option has been deprecated and will be ignored. ASM home: /grid/11.2.0/grid ASM listener: LISTENER unixdev$[/home/grid]srvctl config asm -n unixtest Warning:-n option has been deprecated and will be ignored. ASM home: /grid/11.2.0/grid ASM listener: LISTENER
4.显示OCR中所有注册的数据库
unixdev$[/home/grid]srvctl config database unixdev
4.1查看RAC数据库详细配置
unixdev$[/home/grid]srvctl config database -d unixdev Database unique name: unixdev Database name: unixdev Oracle home: /oracle/app/product/11.2.0 Oracle user: oracle Spfile: +DATA/unixdev/spfileunixdev.ora Domain: Start options: open Stop options: immediate Database role: PRIMARY Management policy: AUTOMATIC Server pools: unixdev Database instances: unixdev11,unixdev12 Disk Groups: DATA,ARC Mount point paths: Services: Type: RAC Database is administrator managed
5.关闭RAC数据库
su - grid srvctl stop database -d node #停止所有节点上的实例 srvctl status database -d node #查看实例状态 Instance instance1 is not running on node rac1 Instance instance2 is not running on node rac2 su - root #必须在root下 cd $grid_HOME/bin ./crsctl stop cluster #停止本节点集群服务 ./crsctl stop cluster -all #停止所有节点集群服务 或 [./crsctl stop cluster -n rac1 rac2]
5.1关闭单节点RAC
su - grid srvctl stop database -d node -i node1 #关闭实例 su - root srvctl stop cluster -n node1 #停止节点集群服务
6.开启RAC数据库
默认开机会自动启动，如果需要手动启动，执行：
su - root cd $grid_HOME/bin ./crsctl start cluster -all #开启集群服务 su - grid srvctl start database -d node #开启实例
6.1开启单节点RAC
su - root srvctl start cluster -n node1 #开启集群服务 su - grid srvctl start database -d node -i node1 #开启实例
7.ocr检查
[[email protected] ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2992
Available space (kbytes) : 259128
ID : 115473992
Device/File Name : +DATA
Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Device/File not configured
Cluster registry integrity check succeeded
Logical corruption check bypassed due to non-privileged user
7.1 查看ocr备份
[[email protected] disks]$ ocrconfig -showbackup #Oracle每4个小时备份一次，保留3个版本 node1 2014/07/28 13:31:50 00.ocr node1 2014/07/28 09:31:49 /grid/product/11.2.0/cdata/node-cluster/backup01.ocr node1 2014/07/28 05:31:49 /grid/product/11.2.0/cdata/node-cluster/backup02.ocr node1 2014/07/27 05:31:48 /grid/product/11.2.0/cdata/node-cluster/day.ocr node1 2014/07/22 16:29:28 /grid/product/11.2.0/cdata/node-cluster/week.ocr PROT-25: Manual backups for the Oracle Cluster Registry are not available
7.2 ocr恢复
su - grid ocrconfig -restore file_name 例如： ocrconfig -restore /grid/product/11.2.0/cdata/node-cluster/backup01.ocr
7.3添加ocr镜像
停掉CRS服务 使用命令ocrconfig -export导出ocr信息
8.查看表决磁盘
unixdev$[/]crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 8c8c1105b3574f13bf8b95d79452e45f (/dev/rdisk/disk18) [OCRVOTE] Located 1 voting disk(s).
