11g RAC 基本命令管理

1.查看当前集群状态

[grid@rac1~]$crs_stat-t
NameTypeTargetStateHost
------------------------------------------------------------
ora.DATA.dgora....up.typeONLINEONLINErac1
ora.GRID.dgora....up.typeONLINEONLINErac1

ora....N1.lsnrora....er.typeONLINEONLINErac2
ora....VERY.dgora....up.typeONLINEONLINErac1

ora.onsora.ons.typeONLINEONLINErac1
ora.rac.dbora....se.typeONLINEONLINErac1

ora.rac1.vipora....t1.typeONLINEONLINErac1
ora....SM2.asmapplicationONLINEONLINErac2
ora....C2.lsnrapplicationONLINEONLINErac2
ora.rac2.gsdapplicationOFFLINEOFFLINE
ora.rac2.onsapplicationONLINEONLINErac2
ora.rac2.vipora....t1.typeONLINEONLINErac2
ora.scan1.vipora....ip.typeONLINEONLINErac2

2.各个状态检查

1）cluster状态

[grid@rac1~]$crsctlcheckcluster
CRS-4537:ClusterReadyServicesisonline
CRS-4529:ClusterSynchronizationServicesisonline
CRS-4533:EventManagerisonline

crs没online

[grid@rac1~]$crsctlcheckcluster
CRS-4535:CannotcommunicatewithClusterReadyServices----看这行，有时需要耐心等待
CRS-4529:ClusterSynchronizationServicesisonline
CRS-4533:EventManagerisonline

当crs服务没online时会报这个错

[grid@rac1~]$crs_stat-t
CRS-0184:CannotcommunicatewiththeCRSdaemon.

当耐心等待过后，crs还是没online的话，那需要通过root用户重启CLUSTER，别的用户没权限

2）nodeapp状态

nodeapp包括GSD,ONS,VIP,LISTENER

[grid@rac1~]$srvctlstatusnodeapps
VIPrac1-vipisenabled
VIPrac1-vipisrunningonnode:rac1
VIPrac2-vipisenabled
VIPrac2-vipisrunningonnode:rac2
Networkisenabled
Networkisrunningonnode:rac1
Networkisrunningonnode:rac2
GSDisdisabled-----------------------------GSD是CRS用于跟9iRAC进行通信的一个模块，为了向后兼容所保留的，默认是disable
GSDisnotrunningonnode:rac1
GSDisnotrunningonnode:rac2
ONSisenabled
ONSdaemonisrunningonnode:rac1
ONSdaemonisrunningonnode:rac2

3）ASM状态

[grid@rac1~]$srvctlstatusASM
ASMisrunningonrac2,rac1

4）数据库状态

[grid@rac1~]$srvctlstatusdatabase-drac
Instancerac1isrunningonnoderac1
Instancerac2isrunningonnoderac2

亦可以查看单个实例状态

[grid@rac1~]$srvctlstatusinstance-drac-irac1
Instancerac1isrunningonnoderac1
[grid@rac1~]$srvctlstatusinstance-drac-irac2
Instancerac2isrunningonnoderac2

5）监听状态

[grid@rac1~]$srvctlstatuslistener
ListenerLISTENERisenabled
ListenerLISTENERisrunningonnode(s):rac2,rac1

3.手工关闭RAC

在Oracle11gR2下的RAC，架构发生了变化。CRS的信息也是放在ASM实例里的，所以要关asm,必须关闭crs,如果还使用了acfs的话，一关crs那么acfs里的信息也不能访问了，所以一般不重启机器，不轻易关crs,其他的service可以根据自己的需要去stop/start

1）关闭TNS监听

2）关闭数据库

3）关闭集群软件（VIP,SCAN_LISTENER,CVU,SCAN_VIP,ONS,NETWORK,ASM）

[grid@rac1~]$srvctlstoplistener

[grid@rac1~]$srvctlstopinstance-drac-irac1

[grid@rac1~]$srvctlstopinstance-drac-irac2

[root@rac1bin]#./crsctlstopcluster-----------以root用户执行，该命令只会对该节点起作用，假如，关闭节点一，你会看到所有应用都会飘到节点二

[root@rac2bin]#./crsctlstopcluster

4.手工启动RAC

1）启动集群软件----11g集群启动较慢，需耐心等待，先看cluster是否online，再去crs_stat-t不断刷新就会看到各应用会慢慢拉起online

2）启动数据库

3）启动TNS监听

启动集群软件

[root@rac1bin]#./crsctlstartcluster

[root@rac2bin]#./crsctlstartcluster

cluster状态

[grid@rac1~]$crsctlcheckcluster
CRS-4537:ClusterReadyServicesisonline
CRS-4529:ClusterSynchronizationServicesisonline
CRS-4533:EventManagerisonline

启动数据库

[grid@rac1~]$srvctlstartinstance-drac-irac1

[grid@rac1~]$srvctlstartinstance-drac-irac2

启动TNS监听

[grid@rac1~]$srvctlstartlistener

最终状态

[grid@rac1~]$crs_stat-t
