Can't ping eth1 in both nodes

by **beto1988** » Wed Oct 03, 2012 4:10 pm

Hello Tim,

I'm following http://www.oracle-base.com/articles/11g ... ualbox.php and when I ping private ip (eth1) of the other node, I can't reach it. But I can ping the other node's public ip. The host is Windows 7 with 8GB of memory.

In the RAC1 node:

Can you please assist me please with it?

I have another question: I performed another install before this one, and did not have any network issue. But during the clusterware installation, the copy files to another node step took more than 9 hours and seemed to be frozen (Runistaller window froze at 67% of installing completed), then I had to cancel it to turn off the notebook, to go to the office. I had to start this second installation. The question is: How long does it take to complete te copy process in the clusterware installation?

Thanks in advance.

Hi.

I can't see a problem with your configuration. I think you just need to go through making sure your /etc/hosts and network adapter settings are consistent on both machine.

Also, make sure the adapters are enabled are reboot. The network configuration screen allows you to check the "start on boot" option for the network adapter definition within the VM.

Regarding the copy time, it really depends on what is happening on your machine. Let's assume all your virtual machines are on the same disk, and you've over-allocated memory, so your machine is swapping like crazy, it's going to take an absolute age to do anything with the disks, like copy the Oracle installation...

Cheers
