Defining a Workstation Listener (WSL) as a Server
Workstation clients access your application through a WSL process and one or more WSH processes. The WSL can support multiple Workstation clients. It acts as the single point of contact for all the Workstation clients connected to your application at the network address specified on the WSL command line. The listener schedules work for one or more Workstation handler processes.
A WSH process acts as a surrogate within the administrative domain of your application for clients on remote workstations. The WSH uses a multiplexing scheme to support multiple Workstation clients concurrently.
To join Workstation clients to an application, you must specify the Workstation listener (WSL) processes in the SERVERS section of the UBBCONFIG file. Use the same syntax you use to specify a server.
Passing Information to a WSL Process
To pass information to a WSL process, you can use the command-line option string, CLOPT. The format of the CLOPT parameter is as follows:
CLOPT="[ -A ] [servopts_options] -- -n netaddr [-d device]
[-w WSHname][-t timeout_factor][-T Client_timeout]
[-m minh][-M maxh][-x mpx_factor ]
[-p minwshport][-P maxwshport]
[-I init_timeout][-c compression_threshold]
[-k compression_threshold]
[-z bits][-Z bits][-H external_netaddr]
[-N network_timeout][-K{client|handler|both|none}]"
The -A option requests that the WSL offer all its services when it is booted. This option is included by default, but it is shown here to emphasize the distinction between system-supplied servers and application servers. When application servers are booted, they sometimes offer only a subset of their available services.
The double-dash (--) marks the beginning of a list of parameters that is passed to the WSL after it has been booted.
Using Command-line Options Set with CLOPT
You can specify any of the following command-line options in the CLOPT string after the double-dash string (--).
Note: For a complete list of the CLOPT command-line options, see servopts(5) in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
