# Step 3: Modify Jackrabbit repository information for PostgreSQL Edit the following code to change the default Jackrabbit repository to PostgreSQL. 1. Navigate to the `pentaho/server/pentaho-server/pentaho-solutions/system/jackrabbit` and open the `repository.xml` file with any text editor. 2. As shown in the table below, locate and verify or change the code so that the PostgreSQL lines are not commented out, but the MySQL, Oracle, and MS SQL Server lines are commented out.
