Order Manager is a standard component of QWFIX system. QWFIX Enterprise Manager provides a graphic tool to edit Order Manager settings associated with a FIX engine.
Order Manager is provided as a "Business Logic" plug-in in FIX engine settings.
Below is a screen shot of the Order Manager Settings Editor GUI.

The toolbar is on top of the editor page. There are three buttons in the toolbar.
Add
sessions: Adds a FIX session to Order Manager.
Remove session: Removes the selected session from the Order Manager.
Refresh: The TabControl in the lower sometimes gets messy after the panel is
resized. We observed that behaviour on Windows Vista X64. While we are stil
investigating the cause of this minor problem, we provided the "refresh" button
to allow user redraw the panel.
