PID

Process ID for the process running Vocalizer.

Value

Any character string

Default

OS-defined process ID for the process running Vocalizer.

How to set

Shown in precedence order (see Rules of parameter precedence):

Set in an environment variable.

In Management Station, set on the Vocalizer service. If not using Management Station, set in the Vocalizer configuration file (User-nvsxx.xml).

Use

Seldom used.

By default, Vocalizer is configured to be safe for use within multiple processes on the same machine. If you enable log files and are using Vocalizer within multiple processes on the same machine, add ${PID} into the log file paths when you change the default configuration.

Vocalizer first looks for an override within the XML configuration file, then an environment variable with the same name, then uses the process ID defined by the operating system.
