In the left pane
of the console, expand Environment >
Servers.
On the Summary of Servers page, select the
server instance for which you will enable native IO.
Expand the

Enter weblogic.socket.NIOSocketMuxer in
the Muxer Class field.
Note: The default Certicom SSL

secure internet communication, Oracle recommends implementing JSSE
(Java Secure Socket Extension).
Click Save.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
