[PRCF-2010 : All connections to the remote nodes got refused. Cannot proceed with the file transfer. There has to be at least one remote node to send the installer files!


I was trying to setup Oracle RAC on my local machine and grid installation worked fine untill 65-70% and I got this weird error. After researching many blogs and sites. I was able to overcome that error and succesfully install the Grid Infrastructure.

[PRCF-2010 : All connections to the remote nodes got refused. Cannot proceed with the file transfer. There has to be at least one remote node to send the installer files!

I have some issues with the instalation of the 11G R2 Grid...

Passed all the prereq checks, everything working but when reaching the - Performing Remote Operations stage it freezes.

Checked the errors and when reaching that stage an error is dumped in the oraInstall.err file:

In the installActions.log file the last lines are:

Solution that worked for me (I think it will work for you people to..) :

This happens basically for various reasons:

1. If both the servers are unable to contact each other due to firewall issues. In order to over this error u have to disable for firewall between both servers. You can do this going to system >> administration >>firewall >> disable.

2.The workaround was to stop the firewall on both nodes using "service iptables stop" during installation - this seems to resolve the issue. 

3. make sure SELINUX is disabled. 

4.Make sure your ssh connectivity is working fine between servers


I found this page very interesting about Multicast :
