# Step 2: Run SQL scripts

To use PostgreSQL as the database for your Pentaho Repository, you must initialize the Jackrabbit, Quartz, Hibernate, and Operations Mart components used by the Pentaho Repository to work with PostgreSQL. You can run SQL scripts developed by Pentaho to create and initialize these components.

Perform the following steps to run the PostgreSQL-specific initialization SQL scripts provided in the Pentaho Data Integration and Analytics software distribution.

**Note:** You may need administrator permissions to run these scripts on the host OS server.

1. Backup your data. See [Back up your existing Pentaho products and install Pentaho 9.3](/install/9.3-install/pentaho-upgrade-cp/use-the-pentaho-upgrade-installer-to-upgrade-archive-installation/back-up-your-pentaho-products-and-install-pentaho-9.1-pentaho-upgrade.md).
2. If the Pentaho Server is currently running, stop it. See [Start and stop the Pentaho Server for configuration](/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/start-and-stop-the-pentaho-server-for-configuration.md).
3. Make sure that your PostgreSQL instance is up and running.
4. Open a PSQL Console window from a terminal and run the following SQL creation scripts in the order shown:

   1. `<*your pentaho directory*>pentaho-server/data/postgresql/create_quartz_postgresql.sql`
   2. `<*your pentaho directory*>pentaho-server/data/postgresql/create_jcr_postgresql.sql`
   3. `<*your pentaho directory*>pentaho-server/data/postgresql/create_repository_postgresql.sql` to initialize Hibernate
   4. `<*your pentaho directory*>pentaho-server/data/postgresql/pentaho_mart_postgresql.sql`

   The Jackrabbit, Quartz, Hibernate, and Pentaho Operations Mart components are created.
5. Start the Pentaho Server.

You have initialized PostgreSQL to be used as the database for the Pentaho Repository.

**Note:** You unpacked the Pentaho Operations Mart SQL file while preparing your environment for the archive installation process. Depending on your environment, see [Prepare your Windows environment for an archive install](https://github.com/pentaho/documentation/blob/main/PDIA/9.3/Install/Pentaho%20installation/Pentaho%20Installation%20\(overview%20cp\)/Archive%20installation/Archive%20installation%20process/Prepare%20your%20Windows%20environment%20for%20an%20archive%20install=GUID-B3F10607-0F15-48A2-9000-586C36CE7811=2=en=.md) or [Prepare your Linux environment for an archive install](/install/9.3-install/pentaho-installation-overview-cp/archive-installation/archive-installation-process/prepare-your-linux-environment-for-an-archive-install.md) for details.
