标题: Oracle 11g RAC vip OFFLINE问题
Oracle 11g RAC其中一个节点vip服务offline，集群从双节点变为单节点

可以看到，ora.dbprd1.vip1状态为OFFLINE，并且ora.LISTENER.lsnr也OFFLINE，监听应该是受vip影响，可以不用去管

检查集群健康状态

[grid@dbprd1 ~]$ 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

其他服务都是正常状态。

查看alert日志
alert日志位置可以通过以下sql查询到
[grid@dbprd1 ~]$ sqlplus / as sysdba

SQL> select * from v$diag_info where name ='Diag Alert';

INST_ID NAME
---------- ----------------------------------------------------------------
VALUE
--------------------------------------------------------------------------------
      1 Diag Alert
/u01/app/grid_base/diag/asm/+asm/+ASM1/alert

alert日志并无错误信息，说明数据库实例并不存在错误

查看系统日志
系统日志位于/var/log/messages文件中，需要用root权限，messages日志会定期归档，所以需要根据你系统出错的时间找到相应日期的日志

messages日志也并未有明显的错误

查看crsd进程日志
vip归crsd进程管，可以查看crsd进程的日志文件，文件位于

/u01/app/11.2.0/grid/log/{SID}/agent/crsd/orarootagent_root/orarootagent_root.log
在日志中找到如下错误

CRS-5005: IP Address: 172.16.200.191 is already in use in the network
. For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/dbprd1/agent/crsd/orarootagent_root//orarootagent_root.log".

172.16.200.191这个ip在rac中作vip使用，从日志可以看出应该是该ip被同个网络中其他主机给用了，而且此时vip服务已经停止但主机缺能ping通，说明确实有使用该ip的主机，反馈给负责人，通过查询果然有一台windows设备使用了该ip，更换windowsip后重启vip，服务恢复正常，重启命令如下：

[grid]

$ srvctl start vip -n dbprd1
