ORACLE-RAC的CRS维护命令总结

有关的均存放在$ORA_CRS_HOME/bin目录下,使用时请多加留意。本文将在日常CRS维护中较常用的命令予以演示,供参考。


1.启动CRS
如果CRS没有启动在使用crs_stat命令查看集群状态的时候将会收到如下的报错信息。
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.

在环境下启动所有节点上的CRS。
[root@rac1 ~]# /oracle/app/crs/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly

[root@rac2 ~]# /oracle/app/crs/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly

集群从启动到全部启动完毕的总时间与系统想能和配置有关,一般需要3~10分钟的时间,请耐心等待。
注意:为保证集群环境可以正常无误的启动,一定要确保集群环境中各个节点的时钟保持一致。

与之对应的停止CRS命令为:“crsctl stop crs”。

2.查看CRS资源状态
集群资源启动完毕后,以在第一节点查看集群状态为例。
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....B1.inst application    ONLINE    ONLINE    rac1
ora....B2.inst application    ONLINE    ONLINE    rac2
ora.RACDB.db   application    ONLINE    ONLINE    rac2
ora....DB1.srv application    ONLINE    ONLINE    rac1
ora....DB2.srv application    ONLINE    ONLINE    rac2
ora.....taf.cs application    ONLINE    ONLINE    rac1
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....C1.lsnr application    ONLINE    ONLINE    rac1
ora.rac1.gsd   application    ONLINE    ONLINE    rac1
ora.rac1.ons   application    ONLINE    ONLINE    rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1
ora....SM2.asm application    ONLINE    ONLINE    rac2
ora....C2.lsnr application    ONLINE    ONLINE    rac2
ora.rac2.gsd   application    ONLINE    ONLINE    rac2
ora.rac2.ons   application    ONLINE    ONLINE    rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2

3.关闭特定集群资源
1)获取集群资源名的方法
crs_stat命令会给出集群资源名的基本信息,结合适当的Shell技巧便可以得到当前环境下集群资源名信息。
RACDB1@rac1 /home/oracle$ crs_stat | grep -i name= | cut -d '=' -f2
ora.RACDB.RACDB1.inst
ora.RACDB.RACDB2.inst
ora.RACDB.db
ora.RACDB.taf.RACDB1.srv
ora.RACDB.taf.RACDB2.srv
ora.RACDB.taf.cs
ora.rac1.ASM1.asm
ora.rac1.LISTENER_RAC1.lsnr
ora.rac1.gsd
ora.rac1.ons
ora.rac1.vip
ora.rac2.ASM2.asm
ora.rac2.LISTENER_RAC2.lsnr
ora.rac2.gsd
ora.rac2.ons
ora.rac2.vip

2)以关闭ora.RACDB.RACDB1.inst资源为例
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stop ora.RACDB.RACDB1.inst
Attempting to stop `ora.RACDB.RACDB1.inst` on member `rac1`
Stop of `ora.RACDB.RACDB1.inst` on member `rac1` succeeded.

提示已成功关闭RACDB1数据库实例。
确认关闭后集群
资源状态:
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....B1.inst application    OFFLINE   OFFLINE
ora....B2.inst application    ONLINE    ONLINE    rac2
ora.RACDB.db   application    ONLINE    ONLINE    rac2
ora....DB1.srv application    ONLINE    OFFLINE
ora....DB2.srv application    ONLINE    ONLINE    rac2
ora.....taf.cs application    ONLINE    ONLINE    rac1
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....C1.lsnr application    ONLINE    ONLINE    rac1
ora.rac1.gsd   application    ONLINE    ONLINE    rac1
ora.rac1.ons   application    ONLINE    ONLINE    rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1
ora....SM2.asm application    ONLINE    ONLINE    rac2
ora....C2.lsnr application    ONLINE    ONLINE    rac2
ora.rac2.gsd   application    ONLINE    ONLINE    rac2
ora.rac2.ons   application    ONLINE    ONLINE    rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2

4.启动特定集群资源
启动ora.RACDB.RACDB1.inst
资源
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_start ora.RACDB.RACDB1.inst
Attempting to start `ora.RACDB.RACDB1.inst` on member `rac1`
Start of `ora.RACDB.RACDB1.inst` on member `rac1` succeeded.

确认启动后状态:
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....B1.inst application    ONLINE    ONLINE    rac1
ora....B2.inst application    ONLINE    ONLINE    rac2
ora.RACDB.db   application    ONLINE    ONLINE    rac2
ora....DB1.srv application    ONLINE    ONLINE    rac1
ora....DB2.srv application    ONLINE    ONLINE    rac2
ora.....taf.cs application    ONLINE    ONLINE    rac1
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....C1.lsnr application    ONLINE    ONLINE    rac1
ora.rac1.gsd   application    ONLINE    ONLINE    rac1
ora.rac1.ons   application    ONLINE    ONLINE    rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1
ora....SM2.asm application    ONLINE    ONLINE    rac2
ora....C2.lsnr application    ONLINE    ONLINE    rac2
ora.rac2.gsd   application    ONLINE    ONLINE    rac2
ora.rac2.ons   application    ONLINE    ONLINE    rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2

5.同时停掉所有集群资源

有关更多的srvctl命令的参考可以通过下面的方法获得:
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/srvctl
Usage: srvctl []
    command: enable|disable|start|stop|relocate|status|add|remove|modify|getenv|setenv|unsetenv|config
    objects: database|instance|service|nodeapps|asm|listener
For detailed help on each command and object and its options use:
    srvctl -h

使用“-h”选项可以获得更加详细的用法。

8.停止当前节点所有CRS资源
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl stop resources

10.对CRS后台进程做健康检查
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

11.检查OCR
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/ocrcheck
Status of  Cluster Registry is as follows :
         Version                  :          2
         Total space (kbytes)     :     104216
         Used space (kbytes)      :       4604
         Available space (kbytes) :      99612
         ID                       :  529429773
         Device/File Name         : /dev/raw/raw1
                                    Device/File integrity check succeeded

                                    Device/File not configured

         Cluster registry integrity check succeeded

12.检查表决磁盘
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl query css votedisk
 0.     0    /dev/raw/raw2

located 1 votedisk(s).
