EMU System Requirements

Workstation Requirements

• Windows XP Professional or Windows 2003 Server (Windows Vista, Windows 7, and Windows 2008 Server are not supported)
• 64 MB RAM (more RAM is required in larger systems - above 5,000 users)
• 20 MB Available Disk Space
• GroupWise Client
• Win32 Novell Client 4.91.5 (does not support 4.91.5 IR1)

Server Operating Systems

Enterprise Management Utility (EMU) is compatible with the following products:

• GroupWise 6x, 7x, and 8.x (running on OES2 or NetWare NSS volumes)
• NetMail 3.x
• all versions of Novell eDirectory
• all versions of Novell Directory Services (NDS)

EMU is compatible with GroupWise, Novell eDirectory/NDS and NetMail installed on the following server platforms:

• Novell OES (requires NSS volumes for GroupWise and Home Directory Management
• Novell NetWare (all versions) 
• SUSE Linux
• Microsoft Windows (no home directory or GroupWise Management)

If you require bulk creation and account management of GroupWise accounts installed on systems that have non-Novell NSS volumes (Windows, OES2 or Linux) contact us for instructions.

Server hardware requirements:

• There are no server hardware requirements.  EMU is a workstation application.  There are no server NLMs or eDirectory extensions to install or configure.

Server access rights, trustee assignments and permissions:

• The administrator using EMU must have appropriate eDirectory, GroupWise and NetMail rights and trustee assignments, and applicable file system rights/permissions on the host server.

LAN/WAN Configuration Options

When you start EMU, it allows you to configure which areas of your Wide Area Network you want to work with.  This significantly enhances EMU's speed when working over slower WAN links.  We recommend you use EMU on a workstation that is connected at LAN speeds to a local Read/Write or Master Replica of the eDirectory partition containing the GroupWise domain and post offices you are working on (rather than accessing that information over a WAN). The speed of any WAN links will be the restricting performance factor when using EMU.

Rights Required

The administrator using EMU needs supervisor rights to the container in which users are going to be created; RWECMFA rights to the appropriate directory structure if home directories are being created; and the necessary rights to create, manage, and delete users in the GroupWise system. We recommend the user running EMU have an explicit Supervisor trustee assignment to the directory in which the users’ home directories are being created. This improves speed when creating or modifying large numbers of home directories.

Performance Considerations

To date, the largest NDS tree managed by EMU contained 80,000 user objects. The upper limit of objects that can be managed in one EMU session is a function of the speed and perfomance of your hardware and network configuration. Time to display information on 12,000 NDS users in a single container: 12 seconds. Time to display information on 12,000 GroupWise users in a single post office: 30 seconds. This benchmark was created on a Pentium II 350MHz computer with 128MB of RAM, running Windows 98, Client32 Version 3.1.0.0, connecting to a Pentium II 266 NetWare 5.0 server running GroupWise 5.5 on 256MB of RAM over a switched 10 megabit Ethernet network.

Following are settings that can increase performance when creating or managing large numbers of home directories. This information was taken from a Novell TID that describes how to improve performance when large directory structures are involved:

• set dirty directory cache delay time = 0.5 seconds
• set directory cache allocation wait time = 0.5 seconds
• set maximum directory cache buffers = 4000
• set minimum directory cache buffers = 2000
