When the connection terminates on a state-reset AppServer, the export list for the disconnected AppServer agent is automatically reset to empty. Thus, you must set any export list on a state-reset AppServer for each new connection and in some procedure that is guaranteed to be executed when you need to have the list set.
You might want to set the export list in the Connect procedure if you know the export list criteria at the start of each connection. The criteria can be based on the user or any other information that you determine at the time of connection. Otherwise, you must set or reset the list in some remote procedure executed by the client.
