[. . . ] 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. If they are, how many servers are available and are these servers load balanced?

Make sure that no single server is overloaded. For information on load balancing mechanisms, see the Citrix Web site (http://www. citrix. com). 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. If there is more than one Citrix server in a farm, you must use the volatile DLU and Roaming Profile policies to enable the users and their profiles to exist on all the servers in the farm. If you do not use the volatile DLU and Roaming Profile policies, a profile synchronization issue might exist among the servers. The idle and disconnected sessions should be periodically logged out to enable the ZENWorks events such as memory release and policy unenforcement to happen. Are the Citrix servers used only to distribute applications or they are also used as terminal servers?You must deploy ZENworks 10 Configuration Management on Citrix Server only if you want the Citrix server to be used as a terminal server in addition to distributing applications. [. . . ] To avoid high consumption of memory on the Citrix server, do one of the following: Ensure that the users log out from a session instead of just disconnecting the session. 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. [. . . ]
