Oracle Study之--Oracle 11gR2 RAC crs啟動故障(CRS-4000)

Oracle Study之--Oracle 11gR2 RAC crs啟動故障(CRS-4000)

系統環境：

    操作系統：RedHat EL5

    Cluster：  Oracle 11gR2 Grid

    Oracle：   Oracle 11gR2 

在啟動一個node的CRS時出現以下錯誤，錯誤現象：

[root@node1 ~]# crsctl start crs  
Failure at scls_scr_getval with code 1  
Internal Error Information:   
  Category: -2  
 Operation: opendir  
  Location: scrsearch2  
  Other: cant open scr home dir scls_scr_getval  
  System Dependent Information: 2  
CRS-4000: Command Start failed, or completed with errors.

查看錯誤原因：

1、主機名

[root@node1 node1]# hostname
node1

2、查看hosts文件

[root@node1 node1]# cat /etc/hosts# Do not remove the following line, or various programs# that require network functionality will fail.

1. 127.0.0.1        localhost  
   ::1             localhost6.localdomain6 localhost6  
   192.168.8.21    wqy1  
   10.10.10.101    wqy1-priv  
   192.168.8.23  wqy1-vip  
     
   192.168.8.22    wqy2  
   10.10.10.102    wqy2-priv  
   192.168.8.24  wqy2-vip  
     
   192.168.8.25  rac-scan  
     
   192.168.8.26    wqy3  
   10.10.10.103    wqy3-priv  
   192.168.8.27  wqy3-vip

從以上可以了解，主機名應該為wqy1，應該是主機名錯誤，導致CRS啟動失敗！

3、重新修改主機名

[root@node1 node1]# vi /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=wqy1

[root@node1 node1]# hostname wqy1

4、重新啟動CRS service

[root@wqy1 ~]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

[root@wqy1 ~]# 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

---至此，問題得以解決！
