试图开启单独监听服务 (因为vip的漂移，一般不会成功) ：
ecsrac02$crs_start ora.ecsrac02.LISTENER_ECSRAC02.lsnr
ecsrac01 : CRS-1019: Resource ora.ecsrac02.LISTENER_ECSRAC02.lsnr (application) cannot run on ecsrac01
ecsrac02 : CRS-1018: Resource ora.ecsrac02.vip (application) is already running on ecsrac01
CRS-0223: Resource 'ora.ecsrac02.LISTENER_ECSRAC02.lsnr' has placement error.
我们可以看到报错中有一个 ecsrac02 : CRS-1018: Resource ora.ecsrac02.vip (application) is already running on ecsrac01 错误， 表示节点2的VIP已经漂移到了节点1 ( 这里节点1机器名称为 ecsrac01 ) 。因为VIP的漂移导致节点2的监听不能在节点1上运行 (节点2本身的监听是正常的，但是只显示一个实例，可以通过lsnrctl stat 查看 ) 。 所以需要监听正常， 首先需要节点2的VIP 重新运行到节点2上。 从 ora....c02.vip application ONLINE ONLINE ecsrac01 上可以看到节点2 VIP 是运行在 ecsrac01 节点1机器上 。
我们在处理监听之前，先处理VIP . 查看节点2 VIP 对应的服务名称 (通过 crs_stat -v 查看 )
ecsrac02$crs_stop ora.ecsrac02.vip

在rac环境中如果使用crs_stop -all去停rac服务时，很有可能会出现crs中的一些服务的状态是UNKNOWN，这时我们可以采用两种方法去重新启动crs服务：
1：转换到root用户下用/etc/init.d/init.crs stop先禁用crs，然后再用/etc/init.d/init.crs start去启用crs，启用crs后会自动启动crs的一系列服务，注意此种方法需要在两台节点上都执行；
2：是用crs_stop -f 参数把crs中状态是UNKNOWN的服务关掉，然后再用crs_start -f （加一个-f的参数）启动所有的服务就可以。参考：
要分别在两个节点上执行；
在启动的过程中最好检测着crs、ASM和数据库的日志：
crs日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/product/10.2.0/crs_1/log/rac1/alertrac1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/product/10.2.0/crs_1/log/rac2/alertrac2.log
ASM日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/admin/+ASM/bdump/alert_+ASM1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/admin/+ASM/bdump/alert_+ASM2.log
数据库日志：
[oracle@rac1 ~]$ tail -f /u01/app/oracle/admin/ora9i/bdump/alert_ora9i1.log
[oracle@rac2 ~]$ tail -f /u01/app/oracle/admin/ora9i/bdump/alert_ora9i2.log
