RCU 11g fails on Oracle Enterprise Linux 6.5 - RCU-6130 and RCU-6136:Error while trying to execute SQLPlus action

Issue:

While running the Repository Creation Utility 11g (RCU) from Oracle Enterprise Linux 6.5 (OEL6.5) 64bit, it is possible to have errors while creating the schema.

The Oracle Universal Installer will first throw errors in the graphical user interface such as RCU-6130 RCU-6136

Upon inspection of the RCU logs (RCU_HOME/rcu/log/logdir.date_timestamp/rcu.log), the following will be seen.

 These errors are most notably seen on Oracle Identity Management and Oracle Identity and Access Management schemas but can occur on any schema.

Resolution:

1. Please verify that Oracle Fusion Middleware is certified on your Linux Release

2. Please verify you have all of the required packages installed for your Operating System

3. Please give full permissions to RCU and it's sub folders before executing $./rcu command

     $cd RCU -> $chmod -R 777 * -> cd rcuHome/bin -> ./rcu

4. If the above steps do not solve the issue please try these potential workarounds.
Currently there is no fix for this issue on OEL6.5

a) Try downloading the Windows Version of the RCU and run it from a certified Windows platform.
b) Try using an older versioin of Linux such as OEL5
c) Try running the RCU from a 32-bit platform


Hope this will resolve your issue!
