Oracle 11gR2 RAC install – installer hangs at 65%

During the install of Oracle 11gR2 RAC Grid, the installer hangs at 65%, with no errors on screen or in the log file.

The problem is the Linux firewall interfering with the install.

Before running the runInstaller script, make sure the firewall is disabled on ALL nodes. Connect as root and disable it as follows:

[root@tbird1 ~]# service iptables stop
Flushing firewall rules: [  OK  ]
Setting chains to policy ACCEPT: filter [  OK  ]
Unloading iptables modules: [  OK  ]


To make sure it stays permanently disabled use the following:

[root@tbird1 init.d]# chkconfig iptables off
