# [CatDRE] Section

The `[CatDRE]` section contains details of the machine that hosts the IDOL category index. The IDOL Category component stores categories in its category index.

In a unified IDOL Server, this section is not required. By default, the IDOL Category component uses the IDOL Agentstore component on the same machine. You can configure `[CatDRE]` if you want to use a different Agentstore.

This section is required in a stand-alone IDOL Category component configuration.
