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
cd $GRID_HOME/bin
./crsctl 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
cd $GRID_HOME/bin
crsctl start cluster -n node1 #开启集群服务
su - grid
srvctl start database -d node -i node1 #开启实例
7、ocr检查
[grid@Node1 ~]$ 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
[grid@Node1 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
