Running the application

This section discusses:

• Starting the DSOM daemon
  
• Running the client

Starting the DSOM daemon

Before running a DSOM application, the DSOM daemon, somdd, must be started.

• On AIX or OS/2, the daemon can be started manually from the command line, or it could be started automatically from a start-up script run at boot time. It may be run in the background with the commands somdd& on AIX and start somdd on OS/2. (The somdd program requires no parameters. An optional -q parameter can be used to set "quiet" mode, to suppress messages.)

• On Windows, the daemon can be started with the DSOM Daemon icon in the SOM icon group or started in Windows from the Run option of the file menu. The DSOM Daemon icon will change colors to indicate the daemon is ready, after which client and server programs can be started.

  The somdd daemon is responsible for establishing a "binding" (that is, a connection) between a client process and a server. It will activate the desired server automatically, if necessary. The server can also be started manually prior to starting the client program, using the command dsom start stackServer.

Running the client

Once the DSOM daemon is running, the application may be started. This is accomplished by running the client program. If the StackServer is not running, it will be started automatically by the DSOM daemon when the client attempts to invoke a method on one of its objects. After the client program ends, the server will continue to run, accepting connections from new clients. To terminate the server, use the command dsom stop stackServer.
