In Progress Version 9.1A, we provide Java programmers who are using the Open Client Toolkit with a set of classes to easily access a SmartDataObject (SDO) running on the AppServer.
One of the capabilities of these new classes is the ability to access an SDO in "stateless" mode. This means that your AppServer can be operating in the "Stateless" mode and that we will not permanently bind the SDO to any given server (which is normally what happens because an SDO is designed to run persistently and doing that in a stateless AppServer environment will "bind" the server to the client that ran the persistent procedure).
However, it is important to understand that even in a Stateless AppServer environment the SDO is temporarily bound to the server process on which it is run. Depending on what you are doing with the SDO it is possible that this period in which the SDO is "bound" to the server can be lengthy and may delay the processing of requests from other users (particularly if you have a very small number of AppServer server processes from which requests are handled).
