Connection 1,***,6201 connect (Connection refused)

The problem Connection 1,***,6201 connect (Connection refused) where *** is the server’s ip address might occur on Oracle Application Server 10g Infrastructure or MiddleTier.

Resolution: This problem is due to file permissions on the Application Server directory (/u01), try a chmod -R oracle:dba on the /u01 directory and then run on both infrastructure and portal.

Warning: My resolution might not always work, you might break your existing installation.(If it is already broken, you might as well give it a try 🙂 )
