11.3.1 Configuration file format

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 may 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 may 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 .
