# Delete All Documents from a Database

You can delete all documents from an Content component database either by sending a `DREDELDBASE` action, or by using the Knowledge Discovery Admin interface.

## Delete All Documents from a Database by Sending an Action

You can delete all documents from an Content component database by sending a `DREDELDBASE` action (case sensitive) from your Web browser:

    http://ContentHost:indexPort/DREDELDBASE?DREDbName=databaseName

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).
`databaseName` | is the name of the database whose documents you want to delete.

For example:

    http://12.3.4.56:20001/DREDELDBASE?DREDbName=Archive

This action uses port `20001` to delete all documents from the `Archive` database on a machine with the IP address `12.3.4.56`.

NOTE: This index action does not complete if the configuration file is read-only.
