Hi,

Recently we had faced network issue due to which node3 server was inaccessible.After the network issue got resolved , node3 was accessbile.So once the issue got fixed , i did a post validation in database and cluster and found listener , network1.org on node3 went offline.

When i try to start listener on node3,i got following error.
grid@RAC3 ~]$ srvctl start listener

[grid@RAC3 ~]$ srvctl status vip -n RAC3

Hi John,

Can you tell me what this srvctl command would do exactly ?
Would there be impact to database and application by restarting vip on node3?
Can we restart vip at any time or should we do this during maintenance window ?

Thank you

Thank you for the link.

Could you answer my other 2 questions ? also could you confirm vip stop and start command?

srvctl stop vip -i vip_name -v

srvctl start vip -i vip_name -v

Thanks

No-one has ever told me the answers to your questions, but you can deduce the answers as I did if you think about for what a VIP is used.
It is a listening address through which a user process contacts a database listener. Then the listener establishes a session for the user process to a server process, through the VIP. RAC complicates the issue bit, because there is an initial request to a SCAN listener followed by a redirection to the VIP, but the end result is the same.

It means that I have come to the conclusion that you can lead some folks to knowledge, but you can't make them think.
