RAC常用管理命令--查询RAC集群各种信息命令-更新中

1.查询RAC集群各种信息命令

数据库名：bysrac

实例名：bysrac1  bysrac1
查集群状态：

[grid@bysrac1 crsd]$ crsctl check cluster

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Services is online

CRS-4533: Event Manager is online

[grid@bysrac1 ~]$ 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

查所有节点实例是否启动：

[grid@bysrac1 crsd]$ srvctl status database -d bysrac

Instance bysrac1 is running on node bysrac1
Instance bysrac2 is running on node bysrac2

集群中所有正在运行的实例 — (SQL语句):

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;

查单个节点实例是否启动：

[grid@bysrac1 crsd]$ srvctl status instance -d bysrac -i bysrac1

Instance bysrac1 is running on node bysrac1
查节点应用程序状态：

[grid@bysrac1 crsd]$ srvctl status nodeapps

VIP bysrac1-vip is enabled

VIP bysrac1-vip is running on node: bysrac1

VIP bysrac2-vip is enabled

VIP bysrac2-vip is running on node: bysrac2

Network is enabled

Network is running on node: bysrac1

Network is running on node: bysrac2

GSD is disabled

GSD is not running on node: bysrac1

GSD is not running on node: bysrac2

ONS is enabled

ONS daemon is running on node: bysrac1

ONS daemon is running on node: bysrac2

eONS is enabled

eONS daemon is running on node: bysrac1

eONS daemon is running on node: bysrac2
列出所配置的数据库名：

[grid@bysrac1 ~]$ srvctl config database

bysrac
列出所配置的数据库的详细信息：

[grid@bysrac1 ~]$ srvctl config database -d bysrac -a

Database unique name: bysrac

Database name: bysrac

Oracle home: /u01/app/oracle/product/11.2.0/dbhome_1

Oracle user: oracle

Spfile: +BYSASMDATA/bysrac/spfilebysrac.ora

Domain:

Start options: open

Stop options: immediate

Database role: PRIMARY

Management policy: AUTOMATIC

Server pools: bysrac

Database instances: bysrac1,bysrac2

Disk Groups: BYSASMDATA,BYSASMDG

Services:

Database is enabled

Database is administrator managed

查看ASM磁盘

[grid@bysrac1 crsd]$ srvctl status asm

ASM is running on bysrac1,bysrac2

[grid@bysrac1 crsd]$ srvctl config asm -a

ASM home: /g01/app/11.2.0/grid

ASM listener: LISTENER

ASM is enabled.
查看listener

[grid@bysrac1 crsd]$ srvctl status listener

Listener LISTENER is enabled

Listener LISTENER is running on node(s): bysrac1,bysrac2

[grid@bysrac1 crsd]$ srvctl config listener -a

Name: LISTENER

Network: 1, Owner: grid

Home: <CRS home>

  /g01/app/11.2.0/grid on node(s) bysrac2,bysrac1

查看各资源状态(nodeapps节点应用程序，ASM实例，数据库等)

状态检查可以用以下三个命令：

crsctl stat resource –t

或者
crsctl stat resource

[grid@bysrac1 ~]$ crs_stat -t

在11g R2中，默认 oc4j和gsd资源是 disable的；oc4j 是用于WLM 的一个资源, WLM在 11.2.0.2 才可用；

gsd是 CRS 用于跟 9i RAC 进行通信的一个模块,是为了向后兼容才保留的，不影响性能；建议不要刪除, 也不要尝试开启他们, 忽略即可。

时钟同步   验证所有集群节点间的时钟同步:

　[grid@rac02 ~]$ cluvfy comp clocksync -verbose
