AIX 5.3下Oracle 10g RAC 啟動故障--vip漂移
系統環境：
操作系統： AIX 5300-09
集群軟件： CRS 10.2.0.1
數據庫： Oracle 10.2.0.1
系統架構圖
故障現象：

每個node都綁定了其他節點的vip ip ，vip ip address 綁定到了所有的節點上！

......
初步判斷是在節點上VIP配置有問題！
解決方法1：
1、關閉所有node上的nodeapps
[oracle@aix213 ~]$srvctl stop nodeapps -n aix213
[oracle@aix213 ~]$srvctl stop nodeapps -n aix214
[oracle@aix213 ~]$srvctl modify nodeapps -A 192.168.8.115/255.255.255.0/en0 -n aix213 -o $ORACLE_HOME
[oracle@aix213 ~]$srvctl modify nodeapps -A 192.168.8.113/255.255.255.0/en0 -n aix214 -o $ORACLE_HOME
2、停止所有節點的crs
[oracle@aix213 ~]$crsctl stop crs
[oracle@aix214 ~]$crsctl stop crs
3、重新啟動所有節點的crs
[oracle@aix213 ~]$crsctl start crs
[oracle@aix214 ~]$crsctl start crs
解決方法2：
1、更新CRS中VIP信息
[root@aix213 racg] cat /etc/hosts
127.0.0.1 loopback localhost # loopback (lo0) name/address 192.168.8.214 aix214 192.168.8.106 aix106 192.168.8.213 aix213 192.168.8.115 aix213-vip 10.10.10.213 aix213-priv 192.168.8.113 aix214-vip 10.10.10.214 aix214-priv
2、修改VIP
[root@aix214 /]$srvctl modify nodeapps -n aix213 -o /u01/app/oracle/product/10.2.0/db_1/ -A 192.168.8.115/255.255.255.0/en0 [root@aix214 /]$srvctl modify nodeapps -n aix214 -o /u01/app/oracle/product/10.2.0/db_1/ -A 192.168.8.113/255.255.255.0/en0
3、以root身份執行vipca
4、重新啟動CRS服務
[root@aix214 /]$crsctl check crs CSS appears healthy CRS appears healthy EVM appears healthy
[root@aix214 /]$crs_stat -t
Name Type Target State Host ------------------------------------------------------------ ora....13.lsnr application OFFLINE OFFLINE ora.aix213.gsd application ONLINE ONLINE aix213 ora.aix213.ons application ONLINE ONLINE aix213 ora.aix213.vip application ONLINE ONLINE aix213 ora....14.lsnr application ONLINE OFFLINE ora.aix214.gsd application ONLINE ONLINE aix214 ora.aix214.ons application ONLINE ONLINE aix214 ora.aix214.vip application ONLINE ONLINE aix214 ora.prod.db application ONLINE OFFLINE ora....d1.inst application OFFLINE OFFLINE ora....d2.inst application ONLINE OFFLINE
手工啟動Listener service：
[root@aix214 /]$crs_stat |grep lsn NAME=ora.aix213.LISTENER_AIX213.lsnr NAME=ora.aix214.LISTENER_AIX214.lsnr [root@aix214 /]$crs_start -f ora.aix214.LISTENER_AIX214.lsnr Attempting to start `ora.aix214.LISTENER_AIX214.lsnr` on member `aix214` Start of `ora.aix214.LISTENER_AIX214.lsnr` on member `aix214` succeeded. [root@aix214 /]$crs_start -f ora.aix213.LISTENER_AIX213.lsnr Attempting to start `ora.aix213.LISTENER_AIX213.lsnr` on member `aix213` Start of `ora.aix213.LISTENER_AIX213.lsnr` on member `aix213` succeeded.
至此CRS啟動成功：
[oracle@aix213 ~]$crs_stat -t
Name Type Target State Host ------------------------------------------------------------ ora....13.lsnr application ONLINE ONLINE aix213 ora.aix213.gsd application ONLINE ONLINE aix213 ora.aix213.ons application ONLINE ONLINE aix213 ora.aix213.vip application ONLINE ONLINE aix213 ora....14.lsnr application ONLINE ONLINE aix214 ora.aix214.gsd application ONLINE ONLINE aix214 ora.aix214.ons application ONLINE ONLINE aix214 ora.aix214.vip application ONLINE ONLINE aix214 ora.prod.db application ONLINE ONLINE aix213 ora....d1.inst application ONLINE ONLINE aix213 ora....d2.inst application ONLINE ONLINE aix214
@至此，問題基本解決
