很多朋友会经常用到oracle 11g RAC的命令，今天我也用到了，同时也整理了一些常用的命令，以备不时之需
1)、检查集群状态：[grid@rac02 ~]$ crsctl check cluster
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
2)、所有 Oracle 实例 —（数据库状态）:
[grid@rac02 ~]$ srvctl status database -d racdb
Instance racdb1 is running on node rac01
Instance racdb2 is running on node rac02
3)、检查单个实例状态：
[grid@rac02 ~]$ srvctl status instance -d racdb -i racdb1
Instance racdb1 is running on node rac01
4)、节点应用程序状态：
[grid@rac02 ~]$ srvctl status nodeapps

7)、ASM状态以及ASM配置：
[grid@rac02 ~]$ srvctl status asm
ASM is running on rac01,rac02
[grid@rac02 ~]$ srvctl config asm -a
ASM home: /u01/app/11.2.0/grid
ASM listener: LISTENER
ASM is enabled.
8)、TNS监听器状态以及配置：

End points: TCP:1521
9)、SCAN状态以及配置：
[grid@rac02 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is running on node rac02
[grid@rac02 ~]$ srvctl config scan
SCAN name: rac-scan.xzxj.edu.cn, Network: 1/192.168.1.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-scan.xzxj.edu.cn/192.168.1.55
10)、VIP各个节点的状态以及配置：
[grid@rac02 ~]$ srvctl status vip -n rac01
VIP rac01-vip is enabled
VIP rac01-vip is running on node: rac01
[grid@rac02 ~]$ srvctl status vip -n rac02
VIP rac02-vip is enabled
VIP rac02-vip is running on node: rac02
[grid@rac02 ~]$ srvctl config vip -n rac01
VIP exists.:rac01
VIP exists.: /rac01-vip/192.168.1.53/255.255.255.0/eth0
[grid@rac02 ~]$ srvctl config vip -n rac02
VIP exists.:rac02
VIP exists.: /rac02-vip/192.168.1.54/255.255.255.0/eth0
11)、节点应用程序配置 —（VIP、GSD、ONS、监听器）
[grid@rac02 ~]$ srvctl config nodeapps -a -g -s -l
-l option has been deprecated and will be ignored.
VIP exists.:rac01
VIP exists.: /rac01-vip/192.168.1.53/255.255.255.0/eth0
VIP exists.:rac02
VIP exists.: /rac02-vip/192.168.1.54/255.255.255.0/eth0
GSD exists.
ONS daemon exists. Local port 6100, remote port 6200
Name: LISTENER
Network: 1, Owner: grid
Home:
/u01/app/11.2.0/grid on node(s) rac02,rac01
End points: TCP:1521
12)、验证所有集群节点间的时钟同步:
[grid@rac02 ~]$ cluvfy comp clocksync -verbose
Verifying Clock Synchronization across the cluster nodes
Checking if Clusterware is installed on all nodes...
Check of Clusterware install passed
Checking if CTSS Resource is running on all nodes...
Check: CTSS Resource running on all nodes
Node Name Status
------------------------------------ ------------------------
rac02 passed
Result: CTSS resource check passed
Querying CTSS for time offset on all nodes...
Result: Query of CTSS for time offset passed
Check CTSS state started...
Check: CTSS state
Node Name State
------------------------------------ ------------------------
rac02 Active
CTSS is in Active state. Proceeding with check of clock time offsets on all nodes...
Reference Time Offset Limit: 1000.0 msecs
Check: Reference Time Offset
Node Name Time Offset Status
------------ ------------------------ ------------------------
rac02 0.0 passed
Time offset is within the specified limits on the following set of nodes:
"[rac02]"
Result: Check of clock time offsets passed
Oracle Cluster Time Synchronization Services check passed
Verification of Clock Synchronization across the cluster nodes was successful.
13)、集群中所有正在运行的实例 — (SQL):
SELECT inst_id , instance_number inst_no , instance_name inst_name , parallel , status ,
database_status db_status , active_state state , host_name host FROM gv$instance ORDER BY inst_id;
14)、所有数据库文件及它们所在的 ASM 磁盘组 — (SQL):
15)、ASM 磁盘卷:
16)、启动和停止集群：
以下操作需用root用户执行。
(1)、在本地服务器上停止Oracle Clusterware 系统：
[root@rac01 ~]# /u01/app/11.2.0/grid/bin/crsctl stop cluster
注：在运行“crsctl stop cluster”命令之后，如果 Oracle Clusterware 管理的
资源中有任何一个还在运行，则整个命令失败。使用 -f 选项无条件地停止所有资源并
停止 Oracle Clusterware 系统。
另请注意，可通过指定 -all 选项在集群中所有服务器上停止 Oracle Clusterware
系统。如下所示，在rac01和rac02上停止oracle clusterware系统：
[root@rac02 ~]# /u01/app/11.2.0/grid/bin/crsctl stop cluster –all
在本地服务器上启动oralce clusterware系统：
[root@rac01 ~]# /u01/app/11.2.0/grid/bin/crsctl start cluster
注：可通过指定 -all 选项在集群中所有服务器上启动 Oracle Clusterware 系统。
[root@rac02 ~]# /u01/app/11.2.0/grid/bin/crsctl start cluster –all
还可以通过列出服务器（各服务器之间以空格分隔）在集群中一个或多个指定的
服务器上启动 Oracle Clusterware 系统：
[root@rac01 ~]# /u01/app/11.2.0/grid/bin/crsctl start cluster -n rac01 rac02
使用 SRVCTL 启动/停止所有实例:
[oracle@rac01 ~]#srvctl stop database -d racdb
[oracle@rac01 ~]#srvctl start database -d racdb
