# DIH Engines Configuration Parameters

If you install and operate the Distributed Index Handler as Integrated with IDOL, you can configure child servers for DAH and Distributed Index Handler separately. This option allows you increased flexibility when querying and indexing content in remote servers. For example, you might define multiple Distributed Index Handler child servers for content that you must index through a combination of failover and mirroring.

Use the `[DIHEngines]` section to set the total number of IDOL servers to which the Distributed Index Handler sends index actions.

You must create a `[DIHEngine` `N``]` subsection for each of the child servers to which Distributed Index Handler sends index actions, and in which you can specify the server configuration details.

For example:

    [DIHEngines]
    Number=2

    [DIHEngine0]
    Host=localhost
    Port=9000

    [DIHEngine1]
    Host=12.3.4.56
    Port=9000

Note: This configuration for the Distributed Index Handler distribution child servers is not used for Standalone Distributed Index Handler.

For integrated configuration in which DAH and Distributed Index Handler are configured together, see Distribution IDOL Servers Configuration Parameters
