Firstly, you need to make sure you set the OIM database to AL32UTF8.

You must also make sure that you're executing RCU on a 32bit environment as you may experience OIM schema issues as mentioned in this belog regarding OIM issue: rcu-6130 action failed - RCU-6136:Error while trying to execute SQLplus action.

To disable the firewall on the linux environment, open terminal and enter in the following command:

startup

Then, by using your arrow on your keyboard, go to Firewall configuration and click enter.

Make sure enable is not ticked, then exit

Disable FW on Windows
Disabling the firewall on windows is more common for most people. You need to go to Control Panel and then Windows Firewall then make sure it's disabled.

As a prerequisite, you need to ensure that both VMs have both internet connections. In my working environment, I have both VM's running with a NAT connection type.

Find out the linux ip address by executing ifconfig

Find out the windows ip address by executing ipconfig

Within the terminal and CMD window, ping the other computer to ensure there's connection between them both.

Example: Ping from Linux VM to Windows
[root@localhost bin]# ping 172.16.7.134
PING 172.16.7.134 (172.16.7.134) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.224/0.299/0.478/0.091 ms

I also wanted to make sure that I could telnet to the linux box to ensure there's no firewall issues. You need to edit the /etc/xinetd.d/telnet file and ensure disable = 0.

# vi /etc/xinetd.d/telnet

# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
 flags = REUSE
 socket_type = stream
 wait = no
 user = root
 server = /usr/sbin/in.telnetd
 log_on_failure += USERID
 disable = no
 log_type = FILE /var/log/telnet.log
}

You will need to start up the telnet service by executing the following command:

service xinetd start

You need to check that the telnet is running by executing the following:

service xinetd status

test the telnet connection from the windows machine. (you need to restart for the service to take place though once you do, make sure the xinetd is up and running.

As soon as you've managed to get the connection between the VM working, proceed by going to the next blog post, HOW TO: Install RCU 11.1.1.6 on Linux 64bit using a 32bit Windows VM (Part 2)
