MASTER is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port. See the List of JANUS DEFINE parameters.
This parameter specifies that this is the default port for outgoing connections to remote servers. A single MASTER port will serve as the access route to multiple external server address spaces.
- The servers may be other Model 204 servers or may be Sybase/Microsoft servers that are to receive Janus Open Client function calls. Users accessing the Model 204 address space over an OPENSERVER port will use the same port they came in on for any outgoing Janus Open Client connections. Users accessing the Model 204 address space with other threads (for example, 3270 or web based applications) must have a MASTER port defined in order for the Janus Open Client functions to establish connections to other address spaces. Note that the port number is irrelevant for outgoing purposes, though it must still be specified.
- The servers may host server sockets for Janus Sockets client (CLSOCK) calls, or (as of Sirius Mods Version 7.9) Janus/Sirius Debugger client (DEBUGGERCLIENT) calls. A single MASTER port will serve as the access route to multiple external servers. A port defined as MASTER can be accessed on a Janus Sockets or Debugger connection request without specifying its port name on the $function, object method, or command that establishes the connection to a remote server socket. The socket port name parameter on $SOCK_CONN, on the Socket object New constructor, on the HTTP Helper Get and Post methods, and on the SIRIUS DEBUG ON command defaults to the MASTER port, if any.
Multiple ports may be DEFINEd and STARTed with the MASTER parameter specified, but the one used in any particular instance will not be predictable.
MASTER is valid only for Janus Sockets client (CLSOCK), DEBUGGERCLIENT, OPENSERV, or SDS ports.
