In BS2000/OSD environments, the Entire Net-Work main task is started as a batch program. It loads the Data Communication Access Method (DCAM) line driver to perform a set of functions related to the communication method.
The DCAM line driver opens a primary DCAM application and establishes DCAM connections to other Entire Net-Work nodes.
Each connection is defined in a LINK statement using SYSDTA or DDKARTE input parameters at startup time. However, some nodes may allow connections to be dynamically established on request from a partner node not previously defined (see the ACCEPTUI parameter in the section DCAM DRIVER Statement ).
The Entire Net-Work DCAM line driver is designed to run under DCAM Version 10 and above and under the BS2000/OSD Version 1.0 and above.
The host computer to which connections are to be established must be interconnected within a TRANSDATA network with the respective entries in the Resource Definition File (RDF).
DCAM Version 10 provides support for the ISO option.
When communicating with heterogeneous machines, it may be necessary to specify the transport selector in ASCII. DCAM Version 10 provides standard support for this (see the APPNAME parameter in the section DCAM DRIVER Statement).
