Editing a mainframe connection

If the Remote Systems window is not displayed, click Window > Show View > Remote Systems.

Restriction: You can only have one MFA Server for z/OS connection defined per workspace. If you require a new connection, you must edit the existing connection, or delete the connection and define a new one.

In the Remote Systems window, right-click the connection name, then click Properties. The Properties window appears.
In the left-hand pane, click Host. The connection details appear in the right-hand pane.
Edit the details in the right-hand pane, then click OK. The connection is updated.

You cannot edit the port number from the Properties window, but you can specify a different port when you log on to the mainframe.
