ora.scan1.vip  ora....ip.type ONLINE    ONLINE    node1

2、检查CRS的状态

1）查看本地节点CRS状态

node1-> crsctl check crs

CRS-4638: Oracle High Availability Services is online

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Services is online

CRS-4533: Event Manager is online

node2-> crsctl check crs

CRS-4638: Oracle High Availability Services is online

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Services is online

CRS-4533: Event Manager is online

2）查看集群CRS状态

node1-> crsctl check cluster

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Services is online

CRS-4533: Event Manager is online

3）查看evm事件管理器状态

node1-> crsctl check evm

CRS-4533: Event Manager is online

3、查看RAC集群里节点的配置信息

node1-> olsnodes

node1

node2

node1-> olsnodes -n -i -s           ---  -n列出节点编号 -i列出虚拟ip -s列出状态

node1   1       node1-vip       Active

node2   2       node2-vip       Active

4、查看RAC集群中软件版本信息

1）查看集群软件使用版本信息

node1-> crsctl query crs activeversion

Oracle Clusterware active version on the cluster is [11.2.0.4.0]

2）查看集群软件发行版本信息

node1-> crsctl query crs releaseversion

Oracle High Availability Services release version on the local node is [11.2.0.4.0]

3）查看集群软件安装版本信息

node1-> crsctl query crs softwareversion

Oracle Clusterware version on node [node1] is [11.2.0.4.0]

5、查看集群软件表决磁盘信息

node1-> crsctl query css votedisk

##  STATE    File Universal Id                File Name Disk group

--  -----    -----------------                --------- ---------

1. ONLINE   2a0486c2db354fbfbf5d5d3b6b2af4fd (ORCL:VOL1) [GRIDDG]

Located 1 voting disk(s).

6、查看系统DNS相关配置信息

node1-> crsctl query dns -servers

CRS-10018: the following configuration was found on the system:

CRS-10019: There are 1 domains in search order. They are:

localdomain

CRS-10022: There are 1 name servers. They are:

172.16.0.191

CRS-10020: number of retry attempts for name lookup is: 4

CRS-10021: timeout for each name lookup is: 5

以上信息来源于：

node1-> cat /etc/resolv.conf

search localdomain

nameserver 172.16.0.191

7、查看集群SCAN VIP信息

node1-> srvctl config scan

SCAN name: scan-cluster.localdomain, Network: 1/172.16.0.0/255.255.240.0/eth0

SCAN VIP name: scan1, IP: /scan-cluster.localdomain/172.16.0.203

node1-> srvctl config scan_listener

SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

8、查看OCR信息

[root@node1 bin]# ./ocrcheck -local

Status of Oracle Local Registry is as follows :

Version                  :          3

Total space (kbytes)     :     262120

Used space (kbytes)      :       2676

Available space (kbytes) :     259444
