# Initialize the Data Index

You can discard the data that your Content component data index contains and reset it to the state it was in when you first installed the Content component. This operation also clears the contents of the index queue, including any queued index actions. Your configuration file is not reset to its initial state.

You can initialize the data index either by sending an action from your Web browser, or by using the Knowledge Discovery Admin interface.

To initialize the data index by sending an action from your Web browser

Send a `DREINITIAL` action (case sensitive) from your Web browser:

    http://ContentHost:indexPort/DREINITIAL?

where:

`ContentHost` | is the IP address or host name of the machine on which the Content component is installed.
`indexPort` | is the Content component index port (specified as `IndexPort` in the `[Server]` section of the Content component configuration file).

OpenText also recommends adding the `InitialID` parameter to the `DREINITIAL` index action. The `DREINITIAL` index action resets the index, so it always returns its index ID as 1. When you set an `InitialID`, the Content GetStatus action reports the `InitialID` of the last `DREINITIAL` that it processed, which allows you to check whether the `DREINITIAL` index action has been completed. The `InitialID` also ensures that if the server receives the same request multiple times, it processes only the first one.

For example:

    http://12.3.4.56:20001/DREINITIAL?InitialID=12345

This action uses port `20001` to reset the data index of an Content component that is located on a machine with the IP address `12.3.4.56` to its original state.

To initialize the data index by using Knowledge Discovery Admin

1. In the Service Control tab in the Console page, click Initialize IDOL Content.

   A confirmation message appears.

2. Click Delete it.

You can monitor the progress of the `DREINITIAL` action in the Recent Tasks panel.
