# IDOL Server Distribution Configuration Parameters

When you use stand-alone components in a distributed IDOL Server, you must configure the `[DataDRE]` configuration section to specify the details of the machine that hosts the IDOL Server data index.

For example:

    [DataDRE]
    ACIPort=9002
    Host=1.23.45.6
    Retries=4
    Timeout=5000

You must configure this section in the Category configuration file when you install Category as a stand-alone component. It configures communications between the Category component and the Content component.

For more information about component-based IDOL setups, refer to the IDOL Getting Started Guide.
