By integrating Novell ZENworks Configuration Management and the Citrix Server, you achieve the following benefits: Improved application accessibility and manageability Strengthened security through Patch Management Improved compliance through Asset Management Improved remote access of applications that are on the Citrix server Allows you to gain simple and one-click access to the applications on the Citrix server. Having all your local and remote software in one place allows you to reduce complexity and increase productivity. Management of the Citrix servers Best Practices for Deploying ZENworks on a Citrix Server 9 novdocx (en) 16 April 2010 Patching of the Citrix servers and the applications hosted on the Citrix servers Load balancing of the Citrix servers Availability of support for the Citrix Server farm that has servers that are a part of an Active Directory forest or a workgroup 1. 2 Gathering Critical Information for Design Activities You need to gather information to help you design your specific implementation for deploying Novell ZENworks 10 Configuration Management on a Citrix Server. Review the following sections: Section 1. 2. 1, "Performing a Technical Assessment, " on page 10 Section 1. 2. 2, "Factors Influencing Scalability, " on page 11 Section 1. 2. 3, "Scale Numbers, " on page 11 Section 1. 2. 4, "Ports Used by the ZENworks Agent, " on page 12 1. 2. 1 Performing a Technical Assessment You need to perform a technical assessment to review what you already have, identify what you need, and document your requirements. You also need to have a good understanding of the existing infrastructure. To do this, you should hold a set of workshops or meetings to obtain all the information you need. The two main results from a technical assessment are documentation on your findings, along with a set of tasks that you need to perform. Information that you should gather includes the following: Which version of Citrix Server should you use?For more information on the supported versions of Citrix Server, see the ZENworks 10 Configuration Management Installation Guide (http://www. novell. com/documentation/zcm10/ index. html). What is the maximum number of user sessions per server that can be active on Citrix Server?If the maximum number of user sessions per server is more than the recommended number, try adding more servers to the Citrix farm. We plan to provide such recommendations for the ZENworks 11 Configuration Management product after the product is released. If it is used, a policy or bundle must be assigned to the users only if the policy or bundle is not applicable to all the users logging in to the server. However, if the policy or bundle is applicable to all the users logging in to the server, assign it to the device instead of assigning it to all the users. For example, if there are 150 bundles that are assigned to the users and 50 bundles are common to all the users logging in to a device, assign these 50 bundles to the device instead of the user. Are servers available in the Citrix farm?If they are, how many servers are available and are these servers load balanced? 10 Deploying ZENworks on a Citrix Server Best Practices Guide novdocx (en) 16 April 2010 Make sure that no single server is overloaded. For information on load balancing mechanisms, see the Citrix Web site (http://www. citrix. com). Is the Novell Client installed on the Citrix server?If the Novell Client is not installed on a Citrix server, the Citrix server session might crash during login. To avoid this issue, see "Tasks to be Performed After Deploying the Agent on Citrix Servers" on page 12. [. . . ] Set a time limit to automatically log out from a disconnected session. For detailed information, see the Microsoft Knowledgebase (http://support. microsoft. com/kb/186566). 1. 6. 4 Disabling Random Refresh Might Cause the ZENWorks Adaptive Agent to Crash on a Citrix Server If Random Refresh for the ZENWorks Adaptive Agent is disabled and if multiple users log in to the Citrix server at the same time, then all the sessions try to refresh at the same time. This can cause resource contention, and subsequently causes the agent to crash because the cache access is not synchronized. To avoid this, Random Refresh must be enabled for the ZENWorks Adaptive Agent. 1. 6. 5 Logging in to the User Source on a ZENworks Server is Slow Logging in to the user source on a ZENworks Server from the managed device might take some time because the login process executes the device refresh synchronously.
