Object-Oriented Programming Using SOM and DSOM:Distributing Your Objects:Execution
Once you have properly set up your environment variables and performed the necessary registration, you can run your DSOM application. To run a DSOM application, the DSOM daemon, somdd, must be started on each server machine. Client-only machines do not require an active DSOM daemon. The daemon can be started from a command line or from a start-up script. For example, start somdd can be used to start the daemon on OS/2.
The DSOM daemon is responsible for establishing a connection between a client process and a server. When a request is made to a server, if the server is not already running, the DSOM daemon will automatically start the server. Once the DSOM daemon is running, the DSOM application can be started.
