DSOM features

Here is a quick summary of some of DSOM's more important features:

• Uses the standard SOM Compiler, Interface Repository, language bindings, and class libraries. Thus, DSOM provides a growth path for non-distributed SOM applications.

• Allows an application program to access a mix of local and remote objects. The fact that an object is remote is transparent to the program.

• Provides run-time services for creating, destroying, identifying, locating, and dispatching methods on remote objects. These services can be overridden or augmented to suit the application.

• Uses existing interprocess communication (IPC) facilities for Workstation communication, and common local area network (LAN) transport facilities for Workgroup communications. Support for TCP/IP, Netware IPX/SPX, and NetBios is provided. DSOM communications is extensible in that an application can provide its own transport.

• Provides support for writing multi-threaded servers and event-driven programs.

• Provides a default object server program, which can be easily used to create SOM objects and make those objects accessible to one or more client programs. If the default server program is used, SOM class libraries are loaded upon demand, so no server programming or compiling is necessary.

• Complies with the CORBA 1.1 specification, which is important for application portability.
