#4 you can De-install using Graphical(OUI) & silent one.

I am going to use GUI method

Connect to the Agent server

Make sure the agent is down.

$ cd $AGENT_HOME/12.1.0.4.0/oui/bin

$ ./runInstaller

You will get the OUI, click on the deinstall products

Step#1  chose the sbin & other plugin homes.

Step#2  remove the agent

Step#3 exit the OUI and clean the $AGENT_HOME location.

If you want you can go ahead with the different agent installation; my case I am hitting a bug where I am asked to installed 32bit agent on the 64bit server.
