Before you attempt to set up an actual system for production use, you should try performing a simple installation. Once you become familiar with the procedures for configuring a HiRDB system by using a sample file to set up a test system, you should be ready to set up a production-use system that is more appropriate to your needs.

For details about how to perform a simple installation, see the HiRDB Version 8 Installation and Design Guide.
