Hi, I got an "ORA-12518: TNS:listener could not hand off client connection" and added the parameter DIRECT_HANDOFF_TTC_LISTENER=OFF to the listener.ora file.

After the restart of the listener I get an "ORA-12547: TNS:lost contact"

Logged users before the 12518 are working but new users can´t log, they get this 12547.

Listener is running, so, where´s the error?

thanks.
