Logon Components,Connections and Connection Pools

The TN5250 connection resource is designed to make an individual connection to the

host on an as-needed basis. The connection is made just-in-time and discarded as soon

as the client is done. It is not reused in any way. This is the type of connection resource

we created in Chapter 2 of this Guide.

The Logon Connection, on the other hand, is different. It defines a pool of User IDs

and passwords, each of which can make its own connection (TN5250). The Logon

Connection also serves as an indirection layer to allow clients to connect to the host at

exactly the point in the host program (exactly the screen) where the client needs to

start. This entry-point-location behavior is made possible by the Logon Component.

(A Logon Connection always uses a Logon Component to get to the actual

connection.) The architecture is shown in the graphic below.
