PMDF System Manager's Guide

The Service Dispatcher configuration file format is similar to the format of other PMDF option files. Lines specifying options have the form

option=value

where option is the name of an option and value is the string or integer to which to set the option. If the option accepts an integer value, value , a base can be specified using notation of the form b%v , where b is the base expressed in base 10 and v is the actual value expressed in base b . Such option specifications are grouped into sections corresponding to the service to which the following option settings apply via lines of the form

SERVICE=service-name

where service-name is the name of a service. Initial option specifications that appear before any such section tag apply globally to all sections. A [SERVICE=DISPATCHER] section can be used to specify options for the Dispatcher itself.

A sample configuration file for an OpenVMS system is shown in Figure 11-2; a sample configuration file for a UNIX system is shown in Figure 11-3; a sample configuration file for an NT system is shown in Figure 11-4.
