# Configure Child Servers

To run QMS, you must configure it to communicate with the data index, and the Promotion Agentstore.

You can use one of the following components to access the data index:

- Distributed Action Handler (DAH), which distributes the actions to child Content components.
- The Proxy component, which forwards the actions to the Content component.
- The Content component, which stores the data index.

To configure child servers for QMS

1. Open the QMS configuration file in a text editor.

2. Find the `[IDOL]` section, or create one if it does not exist.

3. In the `[IDOL]` section, set the Host parameter to the host name or IP address of the server that you use to query the data index (DAH, Proxy, or Content). Set the Port parameter to the ACI port of this server.

   For example:

       [IDOL]
       Host=127.0.0.1
       Port=9000

4. Find the `[PromotionAgentStore]` section, or create one if it does not exist.

5. In the `[PromotionAgentStore]` section, set the Host parameter to the host name or IP address of the machine where the Promotion Agentstore component is installed. Set the Port parameter to the ACI port of the Promotion Agentstore.

   For example:

       [PromotionAgentStore]
       Host=127.0.0.1
       Port=9050

6. If you want to store statistics for QMS, find the `[StatisticsServer]` section, or create one if it does not exist. See StatisticsServer Configuration Parameters.
7. (Optional) Specify the query parameters that QMS can pass through to child servers as the value of the AllowedQueryParameters parameter in the `[Server]` section of the QMS configuration file. Separate multiple parameters with a comma.
8. Save and close the QMS configuration file. Restart QMS for your changes to take effect.
