Thread control methods
The AppServer can be accessed from a multi-threaded client. However, the AppServer itself is not multi-threaded. As a result, only one request is serviced at a time. If a method call is made from the client while another one is still running on the AppServer, the application will decide which of the following should happen:
*The second call can be queued and executed when the AppServer becomes available
*The client can get a Java exception
The application can set the run-time properties to do either and can switch the setting at any time. The default is to throw an exception (WaitIfBusy=false).
The methods in the following table provide thread control to the Open Client Runtime. For a detailed description of each property, see Alphabeticallisting of properties.
