FORMS AND REPORT - An internal operation has failed: A component named emagent_asinst_2 already exis

Hello All,

I am trying to install Oracle Forms and Report 11.1.2.2.0. on RedHat 6.2

Below was the step of installation.

• jdk-7u79-linux-x64.tar.gz was installed
• Web logic 10.3.6  was installed successfully
• Form and Report Instance have been configured successfully
• While Configuring the Forms and Report of above instance, the installer threw an error while trying to create the EM Agent.

An extract from the log is as shown below:
