This document describes how to administer the EntireX RPC Server for IMS Connect, using the Command Central graphical user interface. It covers the following topics:

See also Administering the RPC Server for IMS Connect using the Command Central Command Line. The core Command Central documentation is provided separately and is also available under Guides for Tools Shared by Software AG Products on the Software AG documentation website.

Logging in to Command Central

Open an Internet browser and specify the URL of the Command Central Server as follows: http://<Command_Central_host>:<Command_Central_port>. This takes you to the Command Central Login page.

On Windows you can also get to the Login page from the Command Central Start Menu entry.

Provide your user credentials in the Login page and click Log In. This takes you to the page Home > Instances:
