大致明白了到NODE2的连接有问题，但前面步骤已经对NODE2进行了检查，没发现异常状况，再看看日志，发现crsd.log持续不断的报这种错：

2014-03-22 15:25:21.452: [ CRSRES][1532291392] startRunnable: setting CLI values
/var/log/messages也是持续不断报错:

Mar 23 04:05:02 bssdb02 avahi-daemon[7483]: Withdrawing address record for 10.0.23.136 on eth2.
看来VIP有问题，但ifconfig显示VIP是正常的。

[root@bssdb02 ~]#
既然客户端连接NODE2有问题，那么抓下包呢，用tcpdump配合客户端的连接，但显示到NODE2-VIP没有包过来：
[root@bssdb02 ~]# tcpdump -i eth2 -Z oracle src host 10.25.192.23 and dst host 10.0.23.136 and port 1521
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 96 bytes
0 packets captured
0 packets received by filter
0 packets dropped by kernel
修改下tcpdump设置，但从NODE2-PUBLICIP还是有网路包过来的，如下：
[root@bssdb02 ~]# tcpdump -i eth2 -Z oracle src host 10.25.192.23 and port 1521
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 96 bytes
