Configuration recommendations

Overview

Several configuration settings should be reviewed in your Windows environment to insure that MOMI and other programs can operate to the fullest.

24 bit color or better

The PC must be configured with at least 24 bit color for the client to operate fully. A warning message is displayed at client start up if a lower color depth is detected. While the client will generally function correctly, certain features are not available such as the a pop up window when the mouse is placed over the connector lines between systems on the SubSystems / Expand / Diagram page.

GDI & USER Handles

MOMI makes extensive use of the Windows resource of GDI and USER handles. These values each have a default limit of 10,000.

Increasing these limits allows a Windows program to have more simultaneous graphically intensive screens. This limit may also need to be increased if accessing the Windows desktop remotely via software such as Citrix.

Important: The information below requires modification of the Windows registry. Serious problems might occur if you modify the registry incorrectly. Make sure that you take care and change only the fields recommended. For added protection, back up the registry and/or key being modified before you implement this change.

Run Registry Editor (REGEDT32.EXE).

From the HKEY_LOCAL_MACHINE subtree, go to the following folder:

\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows

On the right hand side of the screen double-click on the key:

GDIProcessHandleQuota

On the pop-up window
a) select a Base of Decimal
b) in the "Value Data:" box enter 15000 (or larger).
c) press OK
On the right hand side of the screen double-click on the key:

USERProcessHandleQuota

On the pop-up window
a) select a Base of Decimal
b) in the "Value Data:" box enter 15000 (or larger).
c) press OK

Exit the Registry Editor and reboot the PC for the changes to take effect.
