Forte 4GL (UDS) basics - distribution

to make a application run on several different servers, Forté uses a specific object called Service Object.

basically a standard class (DummyMgr) is marked as distributed.
then a service object (by convention named DummyMgrSO) based on DummyMgr is defined in the Workshop. behind the scenes Forté creates a proxy that exports all attributes and methods of DummyMgr thus making them remotely available to clients.

the application is partitioned, the first time Forté defines a default partitioning that can be amended, and installed in a given environment on a given server.

dummy application, Client on node P4 & Server partition on node S5





the application is registered with the environment manager, once started the DummyMgrSO is registered with the name service so any client with a TCP/IP connectivity to the environment can get a reference to the DummyMgrSO and call methods or set/get values or variables on it. (accessing attributes may be arguable it is possible).
