Data collectors receive incremental data updates and queries from servers within the zone. Each server farm has a single data store.Ī data collector is a server that hosts an in-memory database that maintains dynamic information about the servers in the zone, such as server loads, session status, published applications, users connected, and license usage. The data store is the database where servers store farm static information, such as configuration information about published applications, users, printers, and servers. Multiple zones are necessary only in large farms that span WANs. The fewest number of zones should be implemented, with one being optimal. All farms have at least one zone, even small ones. The data collector maintains all load and session information for the servers in its zone. Data collectors in farms with more than one zone function as communication gateways with the other zone data collectors. In large farms with multiple zones, each zone has a server designated as its data collector. Lot of services and roles involved, and unless you have done your research it can be troublesome to get the overview you need.So hopefully you will be able to understand a bit more about how xenapp communicates after you have read this post.Ī zone is a grouping of XenApp servers that communicate with a common data collector. Before we prepare for the interview first there are couple of terms that you need to know.
