System Requirements for XenApp 6.5

System requirements for the XenApp server role and the Citrix AppCenter are described below. System requirements for other XenApp features, components, and related technologies are described in their respective system requirements documentation; that includes receivers, plug-ins and agents, Web Interface, Single Sign-on, Service Monitoring, EdgeSight, SmartAuditor, Application Session Recording, Provisioning Services, and Power and Capacity Management.

To ensure the availability of XenApp 6.5 features and correct operation:

• Use the Citrix License Server Version 11.9 (minimum).
• Install the most recent version of any receivers, plug-ins, and agents you use. At the time of its release, XenApp 6.5 was tested with Receiver for Windows 3.0 (with plug-in 13.0). The Citrix Online Plug-in (Web and Full) 12.1 was also tested and can be used, but some XenApp 6.5 features will not be available.

You must be in the Administrators group to install and configure the XenApp server role. Elevating your privilege to local administrator through User Account Control is not a substitute for Administrators group membership.

Important:

• Do not install XenApp on a domain controller. Citrix does not support installing XenApp on a domain controller.
• Do not join servers running this XenApp version to a deployment with servers running previous XenApp versions (including early release and Technical Preview versions).
• You must use the AppCenter from the 6.5 media to manage the XenApp 6.5 farm. Citrix does not support using a console from a previous XenApp release to manage XenApp 6.5 farms. (However, you can use the AppCenter from the XenApp 6.5 media to manage a XenApp 6.0 farm.)
• See Installing and Configuring XenApp for additional guidance, including tasks to complete before installing and configuring XenApp.

Deploying Prerequisites

During a wizard-based installation, the XenApp Server Role Manager (using the Server Role Installer) automatically installs XenApp prerequisites, as noted below.

For command-line installations, you must install the prerequisite software and Windows roles before installing XenApp (except as noted). You can deploy prerequisites with PowerShell cmdlets, the Microsoft ServerManagerCmd.exe command, or the Microsoft Deployment Image Servicing and Management (DISM) tool.

If installation of a required Windows role or other software requires a restart (reboot), restart the server before starting the XenApp server role installation.

XenApp Server Role

Supported operating systems: Windows Server 2008 R2 and Windows Server 2008 R2 SP1 (Enterprise, Standard, Datacenter, and Foundation).

Most servers running the supported operating systems meet the hardware requirements for XenApp with ample processing power to host user sessions accessing the published resources. However, additional research may be needed to determine if current hardware meets the requirements.

• CPU:
  • 64-bit architecture with Intel Pentium
  • Xeon family with Intel Extended Memory 64 Technology
  • AMD Opteron family
  • AMD Athlon 64 family
  • Compatible processor
• Memory: 512MB RAM (minimum)
• Disk space: up to 3.2GB

The XenApp Server Role Manager deploys the following software (except as noted), if it is not already installed:

• .NET Framework 3.5 SP1 (this is a prerequisite for the XenApp Server Role Manager; it is deployed automatically when you choose to add the XenApp server role from the Autorun menu)
• Windows Server Remote Desktop Services role (if you do not have this prerequisite installed, the Server Role Manager installs it and enables the RDP client connection option; you will be asked to restart the server and resume the installation when you log on again)
• Windows Application Server role
• Microsoft Visual C++ 2005 SP1 Redistributable (x64)
• Microsoft Visual C++ 2008 SP1 Redistributable (x64)

When you install the XenApp server role, XML and Internet Integration Service (IIS) integration is an optional component. When this component is installed, the Citrix XML Service and IIS share a port (default = 80). When this component is not installed, the Citrix XML Service defaults to standalone mode with its own port settings. You can change the port during or after XenApp configuration. The Server Role Installer checks for installed IIS role services and whether the component is selected or specified. For complete information, see Before Installing XenApp. The IIS role services are listed below.

• Web Server (IIS) > Common HTTP Features > Default Document (selecting this automatically selects Web Server (IIS) > Management Tools > Management Console, which is not required or checked for XenApp installation)
• Web Server (IIS) > Application Development > ASP.NET (selecting this automatically selects Web Server (IIS) > Application Development > .NET Extensibility; although not checked for XenApp installation, ASP.NET requires .NET Extensibility)
• Web Server (IIS) > Application Development > ISAPI Extensions
• Web Server (IIS) > Application Development > ISAPI Filters
• Web Server (IIS) > Security > Windows Authentication
• Web Server (IIS) > Security > Request Filtering
• Web Server (IIS) > Management Tools > IIS 6 Management Compatibility (includes IIS 6 Metabase Compatibility, IIS 6 WMI Compatibility, IIS 6 Scripting Tools, and IIS 6 Management Console)

If you plan to use Philips SpeechMike devices with XenApp, you may need to install drivers on the servers hosting sessions that record audio before installing XenApp. For more information, see Citrix information on the Philips web site.

AppCenterXenApp Management includes the AppCenter. By default, the AppCenter is installed on the same server where you install the XenApp server role; however, you can install and run the AppCenter on a separate computer. To install the AppCenter on a workstation, from the XenApp Autorun menu, select Manually Install Components > Common Components > Management Consoles.

Supported operating systems:

• Windows Server 2008 R2, 64-bit edition, SP1
• Windows Server 2008 R2, 64-bit edition
• Windows Server 2008 Enterprise, 32-bit edition, SP2
• Windows Server 2003 R2, 32-bit and 64-bit editions
• Windows Server 2003, 32-bit and 64-bit editions, SP2
• Windows 7 Enterprise, 32-bit and 64-bit editions, SP1
• Windows Vista Enterprise, 32-bit and 64-bit editions, SP2
• Windows XP Professional, 32-bit edition, SP3
• Windows XP Professional, 64-bit edition, SP2

Requirements:

• Disk space: 25MB
• Microsoft Management Console (MMC):
  • For Windows Vista, Windows 7, Windows Server 2008 R2, and Windows Server 2008 R2 SP1: MMC 3.0 (installed by default)
  • For other supported Windows operating systems: MMC 2.0 or 3.0

The XenApp Server Role Manager deploys the following software, if it is not already installed:

• Microsoft .NET Framework 3.5 SP1
• Microsoft Windows Installer (MSI) 3.0
• Microsoft Windows Group Policy Management Console
• Microsoft Visual C++ 2005 SP1 Redistributable (x64)
• Microsoft Visual C++ 2008 SP1 Redistributable (x64)
• Microsoft Visual C++ 2008 SP1 Redistributable
• Microsoft Visual C++ 2005 SP1 Redistributable
• Microsoft Primary Interoperability Assemblies 2005

If you install the AppCenter on a computer that previously contained the Microsoft Group Policy Management Console (GPMC) and a Citrix Delivery Services Console earlier than the version delivered with XenApp 6.0, you may also need to uninstall and reinstall the Citrix XenApp Group Policy Management Experience (x64) program in order to use the GPMC to configure Citrix policies.

Data Store Database

The following databases are supported for the XenApp data store:

• Microsoft SQL Server 2008 Express R2
• Microsoft SQL Server 2008 Express SP3
• Microsoft SQL Server 2008 R2
• Microsoft SQL Server 2008 SP2
• Microsoft SQL Server 2005 SP4
• Oracle 11g R2 32-bit Enterprise Edition

Microsoft SQL Server 2008 Express can be deployed for you by the XenApp Server Configuration Tool when creating a XenApp farm.
