Introduction to MetaFrame XP
MetaFrame XP solutions enable you to provide your users with uninterrupted, secure access to your organization’s applications and information, from almost any device over any network connection-Internet, LAN, WAN, dial-up, or wireless. Whether your users rely on Windows or Macintosh PCs or laptops, UNIX or Linux workstations, thin-client devices, Windows-based terminals, wireless devices, or other network appliances, you can use MetaFrame XP solutions to:
• Speed application deployment to thousands of users simultaneously
• Provide your mobile workforce with consistent access to mission-critical data and applications
• Quickly integrate remote offices with your corporate systems after an acquisition or expansion
• Enable fail-over systems for business continuity during an emergency or planned outage
Each MetaFrame XP solution includes the components described below.
MetaFrame XP—the Application Server
MetaFrame XP allows multiple users to log on and run applications in separate, protected sessions on the same server. You install MetaFrame on servers with a multiuser operating system and install and publish the applications or other resources that you want to deploy on the MetaFrame servers. For example, you may want to install office productivity applications (such as word processors and spreadsheets), enterprise resource planning applications such as SAP and Peoplesoft, or any other custom applications.
Chapter 1 Getting Started 9
NFuse Classic—for Integration with Your Web Server
Use NFuse Classic to give users access to published resources through the Web or your Intranet. Users log on to NFuse Classic using the familiar Web browser and see links to the applications that they are authorized to run.
NFuse Classic dynamically creates an HTML page with a depiction of the
MetaFrame XP server farm for each of your users. After logging in, each user sees a Web page that includes all the applications and resources in the MetaFrame XP server farm that you configure for that user.
Using NFuse Classic, you can create stand-alone Web sites for application access or Web sites that can be integrated into your corporate portal.
Any enterprise that relies on the Internet for connectivity must contend with security issues. Despite the enthusiasm for worldwide business communications, corporations must still be assured that they can protect confidential data from prying eyes as it travels through a public network. You can use NFuse Classic with Citrix Secure Gateway to securely transport data over the Internet, using
standards-based security technology.
ICA Clients—for Secure, Remote Access to Applications
Citrix uses the Independent Computing Architecture (ICA) protocol to exchange information between a user’s client device and the published resources on the MetaFrame XP server. The ICA Client software is available for a range of different devices so users can connect to the MetaFrame XP server from various platforms. The ICA protocol sends keystrokes, mouse clicks, and screen updates between the server and the client. Published applications run entirely on the server, which means that processing on the client is kept to a minimum. To the user of the client device, it appears as if the software is running locally.
Because applications run on the server and not on the client device, users can connect from any platform. For example, Microsoft Outlook running on a MetaFrame XPa server looks and feels the same whether the user is connecting from a Windows CE Handheld Computer, a Macintosh desktop or a Linux workstation.
Independent Management Architecture—for Scalable Computing
MetaFrame XP includes the advanced Citrix server communications and management foundation, the Independent Management Architecture (IMA). The integration of the MetaFrame XP application server software with IMA is central to the enhanced functionality of MetaFrame XP and the scalability of Citrix’s server-based computing solutions.
IMA is a unified, enterprise-wide platform for installation, management,
maintenance, support, and security for your organization’s server-based computing and application hosting services. With MetaFrame XP for Windows servers and the Citrix IMA foundation, organizations gain a wide range of enterprise management and scalability features and options that include:
• Centralized administration of MetaFrame XP servers • Centralized data store for all Citrix configuration data
• Centralized license management and pooling without license gateways • ICA Client discovery of published resources without UDP broadcasts • Logging of shadowed sessions
• Simple Network Management Protocol (SNMP) support • Auditing of administration activity
MetaFrame XP Tools—for Unified Management
The management interface for MetaFrame XP servers and server farms is the Citrix Management Console. You can use Citrix Management Console to manage MetaFrame XP servers and server farms from any location. You can install and run the console on any connected Windows NT, Windows XP, or Windows 2000 workstation, in addition to MetaFrame XP server consoles.
Extensible Solutions—for Seamless Integration of Functionality
Many additional features are available as part of various MetaFrame XP solutions. The scalable platform of IMA and the management capabilities of Citrix
Management Console allow you to install and use only the features that you need on each server and customize the server according to your needs and the role of a server in your enterprise.
Many additional components are flexible because you can choose to install them separately. However, all features are integrated into Citrix Management Console rather than separate utilities. This means that you use the same tools to access all of your MetaFrame XP server information. For example, if you install

Overview of the MetaFrame XP
Family
MetaFrame XP is available in three tailored solutions:
• MetaFrame XPs is designed to give businesses outstanding performance from applications running on a central server.
• MetaFrame XPa is designed with the small to medium business in mind. A MetaFrame XPa license enables all of the features of MetaFrame XPs and also includes load balancing functionality.
• MetaFrame XPe is designed for single-point control of servers, licenses, and resources in large organizations and multi-national corporations. A MetaFrame XPe license enables all of the features of MetaFrame XPa and also provides system monitoring and analysis, application packaging and delivery, and integration with third-party SNMP management consoles.
These solutions enable you to install and license only those features and
What’s Included in MetaFrame XPs
Citrix MetaFrame XPs is designed to provide a predictable computing experience with outstanding performance from applications running on a central server. This section describes the components of MetaFrame XPs.
MetaFrame XP
MetaFrame XP is the application server component of Citrix’s server-based computing solutions.
You install MetaFrame XP on one or more servers, and install and publish the applications, server desktop, or other resource that you want users to access. For each server farm, you need a database called a data store. MetaFrame XP uses the data store to centralize configuration information for a server farm in one location. The data store maintains information about the servers, applications, and Citrix administrators in the server farm. Using an external data store ensures a scalable and flexible system for managing your MetaFrame servers.
You can use client/server databases such as Oracle, Microsoft SQL Server, or IBM DB2 for your data store. Alternatively, you can use Microsoft Access, which is a database that is included with Windows server operating systems.
You can install MetaFrame XP from the MetaFrame Server CD-ROM. For conceptual information and procedures for how to install, configure, and maintain MetaFrame XP, see the MetaFrame XP Administrator’s Guide located on the MetaFrame Server CD-ROM.
Citrix Management Console
You can install Citrix Management Console on MetaFrame XP servers, or install it stand-alone on any Windows NT, Windows XP, or Windows 2000 workstation for remote administration of MetaFrame XP server farms.
Chapter 2 Overview of the MetaFrame XP Family 13
ICA Clients
After you install MetaFrame XP and publish your resources, you can connect to your Windows applications from virtually any client device and platform, including:
• All Windows platforms (for example, whether you are using Windows 3.1 or Windows XP, there is an ICA Client for your platform.)
• Java
• Linux and UNIX Operating Systems
• Windows CE handheld computers and Windows-based Terminals • DOS
• OS/2 Warp • Macintosh
You can install the ICA Clients from the MetaFrame XP Components CD-ROM. For an introduction to the methods you can use to deploy clients, see the
MetaFrame XP Administrator’s Guide. Each ICA Client also has a separate ICA Client Administrator’s Guide to help you deploy and configure the client. The client administrator’s guides on the MetaFrame XP Components CD-ROM.
Important Citrix continually updates its ICA Clients to support new client computing platforms and operating system versions. Visit the Citrix Web site download area at http://www.citrix.com/download for information about new and updated ICA Clients.
NFuse Classic
Using NFuse Classic, you can create stand-alone Web sites for application access or Web sites that can be integrated into your corporate portal. An NFuse Classic deployment involves the interaction of three network components:
• A MetaFrame server farm
You can install NFuse Classic in two ways.
• The most common deployment is on a Web server, separate from your MetaFrame XP server farm. In a secure environment, you would most likely include NFuse Classic in the demilitarized zone (DMZ). If you want to install NFuse Classic, install it from the MetaFrame XP Components CD-ROM. • You can also install NFuse Classic on one of your MetaFrame XP servers. If
you do this, you need to set up the MetaFrame XP server as a Web server. If you want to install NFuse Classic in this way, you can select NFuse Classic as a feature when you install MetaFrame XP from the MetaFrame XP Server CD-ROM. Alternatively, you can install NFuse Classic from the MetaFrame XP Components CD-ROM.
Refer to the Citrix NFuse Classic Administrator’s Guide for instructions about how to install, configure, and customize NFuse Classic. This file is located in the NFuse directory on the Components CD-ROM.
Citrix Secure Gateway
Citrix Secure Gateway is a secure Internet gateway for ICA data traveling into and out of a MetaFrame XP server farm. You can secure all traffic traveling across the Internet between MetaFrame XP servers and SSL-enabled ICA Client
workstations. Using Citrix Secure Gateway makes firewall traversal easier and provides heightened security by providing a single point of entry and secure access to your MetaFrame XP server farms.
To use Citrix Secure Gateway, you need to include the following additional components in your deployment:
• A Secure Ticket Authority server. When a user clicks on an application icon in an NFuse Classic Web page, NFuse Classic contacts a service running on a server called the Secure Ticket Authority Server for a “secure ticket.”
• A Secure Gateway server. The user’s connection to the application is then routed through a Secure Gateway server (which is usually in the DMZ). The Gateway server validates the ticket with the Secure Ticket Authority. If the ticket is valid, the Secure Ticket Authority provides the address of the MetaFrame XP server that can provide the application.
You install Citrix Secure Gateway server and the Secure Ticket Authority service from the MetaFrame XP Components CD-ROM.
Chapter 2 Overview of the MetaFrame XP Family 15
Citrix SSL Relay
If you want to secure all communications within your environment using SSL or TLS, you can use SSL Relay to secure communications between supported ICA Clients, NFuse Classic, and MetaFrame XP servers.
To deploy SSL Relay, you need server certificates on each of your MetaFrame XP or NFuse Classic servers.
SSL Relay is a feature of all MetaFrame XP server installations.
For more information about SSL Relay, see the MetaFrame XP Administrator’s Guide and the online help for the SSL Relay configuration tool.
What’s Included in MetaFrame XPa
Citrix MetaFrame XPa is designed with the small to medium business in mind. A MetaFrame XPa license enables all of the features of MetaFrame XPs and also provides advanced load management using Load Manager.
Load Manager
You can set up, monitor, and balance the server and published application loads in a server farm so that users can run the published applications they need quickly and efficiently.
The criteria you define in Load Manager determine which servers are least busy and can best run an application. When a published resource is launched from an ICA Client, Load Manager selects which server will run the application or desktop session, based on server load. Load Manager ensures that the application runs on a server that is not overloaded, and so improves performance for users.
Using Load Manager also offers increased availability. By configuring a pool of servers capable of running your users’ applications, you can easily bring servers off-line for maintenance or add more servers for increased performance without affecting application availability.
What’s Included in MetaFrame XPe
Citrix MetaFrame XPe offers robust management capabilities specifically designed for single-point control of servers, licenses, and resources. It is designed for IT administrators in large organizations and multi-national corporations who must manage complex networks that include diverse devices and operating systems. A MetaFrame XPe license enables all of the features of MetaFrame XPa and also provides:
• System monitoring and analysis using Resource Manager
• Application packaging and delivery using Installation Manager
• Systems management capabilities using Network Manager and third-party SNMP management consoles
• Aggregation of applications from multiple server farms using Enterprise Services for NFuse
Resource Manager
Resource Manager enables you to collect, display, and analyze data about system performance, application use, and user activity.
Resource Manager can track and store information about a wide variety of system and network processes and events. If the value of these metrics fall outside normal limits, Resource Manager can warn you by email and pager alerts.
You can also use Resource Manager to store longer term data in an external Microsoft SQL Server or Oracle database. You can use the summary database to retrieve historical records on processes, server events, server metrics, and user activities for individual servers or groups of servers. You can also generate bills based on resource usage.
Resource Manager is a feature of a MetaFrame XPe server installation. You can choose to include it in your installation when you run the installation program on your MetaFrame XP Server CD-ROM.
Chapter 2 Overview of the MetaFrame XP Family 17
Network Manager
Network Manager allows you to remotely control and monitor the status of MetaFrame XPe servers using a third-party SNMP management console.
Network Manager consists of an SNMP agent installed as part of MetaFrame XPe and plug-ins for supported SNMP management console applications. Using a third-party SNMP management console, you can terminate processes on MetaFrame XPe servers, as well as send a message to, log off, or disconnect an active ICA session on a MetaFrame XPe server.
Network Manager also includes the MIB (Management Information Base)
definition file for MetaFrame servers. You can use any SNMP management console application that supports MIB browsing to monitor and control MetaFrame XPe servers.
The Network Manager plug-ins interact with the SNMP management consoles through API calls provided by the SNMP management consoles. The Network Manager plug-ins automatically:
• Explore and gather information from MetaFrame XPe servers with the SNMP agent enabled
• Update the gathered data on the network map
• Log MetaFrame XPe server traps in the event database
Network Manager includes Windows plug-ins for the following SNMP management console applications:
• Tivoli NetView
• HP OpenView Network Node Manager • CA Unicenter
Important Check the Network Manager Administrator’s Guide for details about the versions of the SNMP management consoles that the Network Manager plug-ins support.
Installation Manager
You can use Installation Manager to install applications on the servers in your MetaFrame XP server farm from a central location.
Installation Manager lets you install an application package, such as Microsoft Office 2000, from one server to all the servers in a domain or in a server farm. Use Installation Manager whenever you need to deploy applications, files, service packs, or software patches on the servers in your server farm.
You can automate the application installation process, enabling the replication of published applications to MetaFrame XP servers across an enterprise. Automating the process enables you to save time and reduce errors when installing many applications or applications that are frequently updated.
Installation Manager is installed with MetaFrame XPe.
For more information about the Installation Manager, see the Installation Manager Administrator’s Guide located on the MetaFrame XP Server CD-ROM.
Enterprise Services for NFuse
Enterprise Services for NFuse extends NFuse Classic by giving users resources published from multiple MetaFrame server farms on a single Web page. This process, called aggregation, greatly simplifies user access to applications in organizations that have more than one MetaFrame server farm.
You can configure and manage Enterprise Services for NFuse using a Web browser. You install Enterprise Services for NFuse from the MetaFrame XP Components CD-ROM. For more information about Enterprise Services for NFuse, see the

Frequently Asked Questions
This section describes some of the areas you need to consider when you start to deploy MetaFrame XP. For more detailed information see:
• The MetaFrame XP Administrator’s Guide on your MetaFrame XP Server CD-ROM or installed on your MetaFrame XP server
• The MetaFrame XP Advanced Concepts Guide on the Citrix Web site
Planning Your MetaFrame XP Deployment
Deploying MetaFrame XP requires planning and you’ll most likely plan to deploy your system in stages.
How Do I Plan the Stages for Deploying MetaFrame XP?
A phased approach to planning and deploying MetaFrame XP allows you to tweak and enhance your server farm design as you progress. The stages usually include: • A planning phase, to help you identify the hardware or application requirements
for your environment.
• A testing phase, to identify and fix potential issues with the planned MetaFrame XP server farm design.
• A pilot phase, to “test drive” your MetaFrame XP solution in a live production environment. The pilot implementation is the proving ground for network designs, application compatibility, and other requirements that you identify during your planning and testing phases. Make sure that your pilot includes a typical sample of the actual production environment with real users. The pilot provides the baseline environment on which you can test additional
enhancements.
How Do I Choose and Size the Hardware that I Need?
MetaFrame XP supports many simultaneous application users by running on a multiuser operating system. Multiuser operating systems are more resource intensive than single-user systems. You’ll first need to use the system sizing guidelines to help you decide on a hardware configuration that will support your users with optimal performance.
A good way to estimate how many users a server can support is to measure system performance with two to five users on the system and then scale the results. This method has been found to yield reliable results.
For more information, see the Citrix Knowledgebase, at
http://www.citrix.com/support. Here, you can find articles about installing MetaFrame XP on many different types and makes of server.
How Do I Choose a Database for the Data Store?
Before installing MetaFrame XP, you must decide which database to use for the data store for your server farm.
• For a server farm of any size, and for robust and scalable support for multiple servers, use a true client/server database, such as Microsoft SQL Server, Oracle, or IBM DB2.
• For smaller server farms or for pilot systems, you may prefer to use Microsoft Access, a database that is included with Windows server operating systems. If you want to use an Access database for your data store, select this option when you install MetaFrame XP on the first server in your server farm. MetaFrame XP automatically creates the database on this server.
Chapter 3 Frequently Asked Questions 21
Licensing MetaFrame XP
To complete the installation of MetaFrame XP, you need to activate your Citrix licenses to permit ICA connections to the server and enable the software for use. Citrix licensing involves several types of licensing codes and concepts.
• A product license is a license to install and run one or more Citrix components. MetaFrame XP allocates product licenses from a pool of available licenses for a MetaFrame XP server farm.
• A product code identifies a legitimate copy of Citrix software. The product code on a server specifies which product license the server takes from the license pool for the server farm.
• A connection license is a license that enables ICA Client connections to MetaFrame servers. A connection license can contain multiple counts. Each count allows a single ICA connection to a MetaFrame server.
Every licensed Citrix product has an associated serial number. After you install the software, you enter the serial number and a license number is generated. You use this license number to get an activation code to activate the license. An overview of the steps required is described in this section. For more information about licensing, see the chapter “Licensing MetaFrame XP” in the MetaFrame XP Administrator’s Guide.
How Do I Activate a MetaFrame XP License?
There are four steps to activating a Citrix license.
Step 1 - Add Your Serial Number
Add the supplied serial number in Citrix Management Console. The serial number is the number located:
• On a label on the product package
Step 2 - Log On to the Citrix Activation System
Log on to the Citrix Activation System (CAS) Web page at
http://www.citrix.com/activate. When you first visit, you set up an account and password.
From this secure site, you can manage the activation of your MetaFrame XP licenses.
Step 3 - Get an Activation Code
For each license, you need to get an activation code from the CAS Web page. In this step, you use the full license number generated in Step 1 (that is, with the machine code appended), and then copy the activation code that you receive for the license.
Step 4 - Activate the License
Activate the Citrix license using Citrix Management Console. You must select the license and activate it using the activation code from the previous step.
How Long do I Have Before I Must Activate a License?
Citrix licenses have a grace period after installation. During this period, your MetaFrame XP software is fully functional and users can connect to the server and work normally. Citrix recommends that you use the grace period to thoroughly test your hardware and software configuration. When you are sure that your system is set up properly, activate your licenses.
Important The duration of the grace period varies according to the type of license. For example, most retail licenses have a 35-day grace period and most
MetaFrame XP evaluation licenses have a 2-day grace period. After you add the license, you can check the number of days remaining in the grace period from the licensing tab in Citrix Management Console.
MetaFrame XP generates periodic reminder messages to prompt you to activate the license within the grace period. To avoid disrupting user access to published resources, make sure that you activate the license before the end of the grace period. If the grace period does expire, the license prevents user connections to
Chapter 3 Frequently Asked Questions 23
How Do I Upgrade a MetaFrame 1.8 License?
MetaFrame XP does not directly support licenses for MetaFrame 1.8. However, you can use a MetaFrame 1.8 license if you also purchase the appropriate product migration licenses.
If you have a MetaFrame 1.8 system and purchase a MetaFrame XP migration license, how you apply the licenses to the system depends on whether or not you are able to keep the activated MetaFrame 1.8 licenses on the system.
• If you are able to keep the activated MetaFrame 1.8 licenses on the system (for example, during a simple upgrade), do not remove your MetaFrame 1.8 licenses. When you install MetaFrame XP on an existing MetaFrame 1.8 server, Setup migrates existing licenses into the new MetaFrame XP server farm. • If you are unable to keep the MetaFrame 1.8 licenses on the system (for
example, because you reinstalled the operating system), you need to add both the MetaFrame 1.8 and MetaFrame XP migration licenses. When you install MetaFrame XP, you must first add the MetaFrame 1.8 licenses in Citrix Management Console, reactivate the MetaFrame 1.8 licenses, and then add and activate the MetaFrame XP migration licenses.
You will not be able to use the connections in your MetaFrame 1.8 base license with a MetaFrame XP deployment until you install and activate the appropriate
MetaFrame XP migration license.
