Shulou(Shulou.com)06/01 Report--

Environment: aix 7.1, oracle 12.1.0.2 rac-3 nodes.

After the hardware failure, the hardware engineer replaced the intranet card. I don't know why there was a problem with the resource VIP, so I had to add VIP first.

Srvctl add vip-node rac-wy1- address rac-wy1-vip.nsn.com/255.255.255.0/en8

Modified the nodeapps

Srvctl modify nodeapps-node rac-wy1-address 10.48.186.99/255.255.255.0/en8

Start listener

Srvctl start listener-node rac-wy1

Report a failure.

I checked a lot of information, but I didn't get anything special.

There is a problem with the configuration string in listener.ora under grid, but it is not consistent with that in gv$configured_interconnects. I don't know which dog egg has been modified!

Anyway, first according to gv$ to modify it, and then restart, the result is ok!

Go back and use ifconfig-a to see:

From this point of view, public,vip,scan is on the same network card, while private (inline) is on the same card as LISTENER (replaced).

It is speculated that the ip was modified after the network card was replaced (not sure whether it was assigned by the system or modified by the engineer), but it was caused by not modifying the listener.ora file of the grid.

It seems that we need to strengthen communication in the future!
