【RAC】使用頻率較高的CRS維護命令總結

kingsql發表於2014-08-14
與CRS有關的命令均存放在$ORA_CRS_HOME/bin目錄下，使用時請多加留意。本文將在日常CRS維護中較常用的命令予以演示，供參考。

1.啟動CRS
如果CRS沒有啟動在使用crs_stat命令檢視叢集狀態的時候將會收到如下的報錯資訊。
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.

在RAC環境下啟動所有節點上的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

叢集從啟動到全部啟動完畢的總時間與系統想能和配置有關，一般需要3~10分鐘的時間，請耐心等待。
注意：為保證叢集環境可以正常無誤的啟動，一定要確保叢集環境中各個節點的時鐘保持一致。

與之對應的停止CRS命令為：“crsctl stop crs”。

2.檢視CRS資源狀態
叢集資源啟動完畢後，以在第一節點檢視叢集狀態為例。
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.關閉特定叢集資源
1）獲取叢集資源名的方法
crs_stat命令會給出叢集資源名的基本資訊，結合適當的Shell技巧便可以得到當前環境下叢集資源名資訊。
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）以關閉ora.RACDB.RACDB1.inst資源為例
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.

提示已成功關閉RACDB1資料庫例項。
確認關閉後叢集資源狀態：
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.啟動特定叢集資源
啟動ora.RACDB.RACDB1.inst資源
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.

確認啟動後狀態：
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

RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/srvctl start nodeapps -n rac1
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    rac1
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

有關更多的srvctl命令的參考可以透過下面的方法獲得：
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”選項可以獲得更加詳細的用法。

8.停止當前節點所有CRS資源
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl stop resources
Stopping resources. This could take several minutes.
Successfully stopped CRS resources.

RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crs_stat -t

ora.rac2.gsd   application    ONLINE    ONLINE    rac2
ora.rac2.ons   application    ONLINE    ONLINE    rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2

9.啟動當前節點所有CRS資源
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl start resources
Starting resources.
Successfully started CRS resources
RACDB1@rac1 /home/oracle$ crs_stat -t

10.對CRS後臺程式做健康檢查
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy

11.檢查OCR
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/ocrcheck
Status of Oracle 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.檢查表決磁碟
RACDB1@rac1 /home/oracle$ /oracle/app/crs/bin/crsctl query css votedisk
 0.     0    /dev/raw/raw2

located 1 votedisk(s).

13.小結
以上演示了在RAC環境與CRS有關的維護命令，這些命令的使用頻率較高，需要熟練掌握。管理CRS的命令較多，建議對每一個命令的具體選項做實際的測試，以便降低誤操作的風險。

Good luck.
