Turn on the tracing of listener and re-execute the operation. Then see the error message in listener.log

This one was puzzling.  I could connect from the client with SQL*plus.  Forms wouldn't connect.  I removed all Oracle products and reinstalled.  Same problem.  I discovered that the user had installed McAfee Firewall. The Oracle Forms Runtime came up like it wanted to access the Internet. The user was paranoid and BLOCKED all access to the Forms Runtime module.  I changed the access to PERMIT and problem solved.

Thanks for your help.
