Re: wish to remove logical IP address from lan901:802

"ifconfig lan901:802 down" will remove the virtual ip online ... BUt ...

"without bringing the RAC down !!!".... we can't say anything... as you said its oracle RAC-VIP , there is a chance the rac node can went down.

My question is that, does your application going to effect even one rac node went down ??? i feel there won't be any problem for your application...

Pls check with DBA team

Re: wish to remove logical IP address from lan901:802

the above excerpts are from the node1 netstat -inv
i did an ifconfig lan901:802 down that is having IP address 10.29.8.48 on node1.

but this is vip of 4th node of the 4 node CRS cluster.


still as this is down or up when i do ssh to the IP 10.29.8.48 this is taking me to the 1st node whereas this should take me to the 4th node as this is ora-vip of node4.

i tried doing an arp -d 10.29.8.48 on 1st node but and putting new entry of arp for node4 like this on node1 like
arp -s 10.29.8.48

but still the same thing.

ssh 10.29.8.48 takes me to node1 from node1 whether this should take me to node4 when executed forrm node1.

Re: wish to remove logical IP address from lan901:802


Does we missing somthing from oracle side ?
