Oracle 10g RAC监听报TNS-12545 TNS-12560 TNS-00515
昨日在客户现场一套RAC在启动监听的时候报TNS-12545 TNS-12560 TNS-00515错误，经过处理后恢复正常，
今天在自己的虚拟机上还原了这个问题，记录下：
OS:Linux
DB:10.2.0.4 RAC
一、模拟恢复到事故发生时的情况
1、手工关闭监听后切换VIP
[Oracle@orlrac1 ~]$
[oracle@orlrac1 ~]$ srvctl stop listener -n orlrac1
[oracle@orlrac1 ~]$ srvctl stop listener -n orlrac2
[oracle@orlrac1 ~]$
[oracle@orlrac1 ~]$
[oracle@orlrac1 ~]$ crs_stat -t

[oracle@orlrac1 ~]$
2、手工切换vip ------问题的关键，昨天的问题是两个节点的VIP不知道什么原因互换了
[oracle@orlrac1 ~]$ crs_relocate ora.orlrac1.vip -c orlrac2
Attempting to stop `ora.orlrac1.vip` on member `orlrac1`
Stop of `ora.orlrac1.vip` on member `orlrac1` succeeded.
Attempting to start `ora.orlrac1.vip` on member `orlrac2`
Start of `ora.orlrac1.vip` on member `orlrac2` succeeded.
