What is UNIX Resident MileMaker®?

UNIX Resident MileMaker® is a Rand McNally routing and mileage calculation application that runs as a resident process on UNIX-based servers. It provides HHG (Household Goods) and Practical route mileage calculations, state-by-state mileage breakdowns, and route optimization across the US and Canada. The application is designed for integration with client systems via an Application Communication Area (ACA), supporting named pipes and TCP/IP communication protocols.

Who this guide is for

• System Administrators — IT staff responsible for installing, configuring, and maintaining the MileMaker application on UNIX servers, managing environment variables, user credentials, and system updates.
• Application Users — Staff who operate the MileMaker interface directly to perform mileage inquiries, retrieve routes, and manage routing preferences and user-defined locations.
• Integration Developers — Technical staff connecting client applications to MileMaker via the ACA using named pipes or TCP/IP, or working with request/response record formats programmatically.

Note for System Administrators: 
MileMaker uses environment variables to assign file names and configure application behavior — these must be set correctly before installation. The Application Communication Area (ACA) supports three integration versions (named pipes, non-named pipes, and TCP/IP); confirm which version is appropriate for your environment before configuring client connections. 

Not all features described in the manual may be included in your licensed product — refer to your contract for details.
