11.6 Debugging and Log Files

Service Dispatcher error and debugging output (if enabled) are written to the file dispatcher.log in the PMDF log directory.

Debugging output can be enabled using the option DEBUG in the Dispatcher configuration file, or on a per-process level, via the PMDF_DISPATCHER_DEBUG logical (OpenVMS) or environment variable (UNIX or NT).

The DEBUG option or PMDF_DISPATCHER_DEBUG logical name (OpenVMS) or environment variable (UNIX or NT) defines a 32-bit debug mask in hexadecimal. Enabling all debugging is done by setting the option to -1, or by defining the logical or environment variable system-wide to the value FFFFFFFF. The actual meaning of each bit is described in Table 11-2.
