# Step 4: (Optional) Unpack the Operations Mart DDL files

The Pentaho Operations Mart distribution file is a package file and needs to be unpacked.

1. Unzip the Pentaho Operations Mart distribution file to a folder.

   The packaged installation file is in the folder.
2. Run the `install.bat` file to unpack the installation file.

   The IZPak window appears.
3. Read the license agreement in the IZPack window. Select the **I accept the terms of this license agreement** check box, and then click **Next.**
4. In the **Select the installation path** text box, browse to and save the file in the `pentaho\server\pentaho-server\data` directory, then click **Next.**

   A warning message appears informing you that the directory already exists.
5. Click **Yes**.

   Any existing files in the directory will be retained.
6. Click **Quit** when the installation progress is complete.
7. Unzip the `pentaho-operations-mart-ddl-9.3.0.zip` file.
8. Move the directory for your database into `pentaho\server\pentaho-server\data\<database name>` and delete the others.

   The appropriate database names are shown in the following table:

   | If your Pentaho Repository is on: | Copy this directory into `pentaho\server\pentaho-server\data\` |
   | --------------------------------- | -------------------------------------------------------------- |
   | PostgreSQL                        | `postgresql`                                                   |
   | MySQL                             | `mysql5`                                                       |
   | Oracle                            | `oracle10g`                                                    |
   | MS SQL Server                     | `sqlserver`                                                    |
9. Complete the steps for installing Data Integration Operations Mart in the **Administer Pentaho Data Integration and Analytics** document before installing your database.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/9.3-install/pentaho-installation-overview-cp/archive-installation/archive-installation-process/prepare-your-linux-environment-for-an-archive-install/download-and-unpack-installation-files/step-4-unpack-the-operations-mart-ddl-files-reuse.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
