Session Host: Can’t participate in ZDC election process, so can’t be ZDC or XML broker or Management server. XenApp 6.5 => A xenapp server can have two roles. Farms determine the data collector based on the election preferences set for a server. When the zone’s data collector fails, a data collector election occurs and another server takes over the data collector functionality. By default, the data collector is configured on the first server when you create the farm, and all other servers configured with the controller server mode have equal rights to become the data collector if the data collector fails. Data collectors relay information to all other data collectors in the farm.
Data collectors receive incremental data updates and queries from servers within the zone.

A farm may have multiple zones based on subnet/location, by default one zone.ĭatastores : Is the database which contain the static information related Xenapp farm which includes – published applications, users, printers, and servers, citrix GPOĭataCollector (ZDC): maintains dynamic information about the servers in the zone, such as server loads, session status, published applications, users connected, and license usage. Zone: A zone is a grouping of XenApp servers that communicate with a common data collector. IMA – 2512 (server to server) & 2513 (for App center)įarm: A logical collection or group of XenApp servers that can be managed as a single entity and they talk to single datastore server. What are the different ports and their numbers? ICA supports non windows platforms like DOS, Unix, mobiles etc Session reliability (keeps the user session action active when network connection is interrupted) is supported by ICA. ICA allows applications to run in browser. It works in presentation layer in OSI model. ICA (Independent Computing Architecture):Ĭreate virtual channels(video,audio,print,keyboard& mouse updates up to 32 virtual channels ) and transfers only screen updates. RDP doesn’t permit applications to run in browser Transfers complete frame and bandwith depends on screen resolution. What is the difference between RDP and ICA ?
