The Database Connector is a web application that allows you to easily integrate your frevvo forms and workflows with your external database. The connector can be added to your frevvo tomcat bundle. A Standalone Bundle is also available.

Info

frevvo only supports/certifies the Database Connector running in the tomcat container. Refer to our Supported Platforms for the list of Application Servers and databases supported/certified by frevvo.

Cloud customers who are integrating with their on premise database and On Premise customers can choose to:

  • install the Database Connector in your frevvo tomcat bundle on their in-house server OR
  • install the Standalone Bundle on their in-house server

We recommend the frevvo-tomcat bundle for in-house customers. Follow the frevvo-tomcat Bundle Instructions.

We recommend the Standalone bundle for cloud customers as no additional servlet container is needed. Standalone is also useful for in-house customers who want to run the connector on a different server than the frevvo server installation. Follow the Standalone Bundle Instructions

The Database Connector requires a JDBC driver for your database. Some pre-installed drivers are included with the connector. See Install a JDBC driver to see if the driver for your database is provided.

The Database Connector contains a working sample Derby database with BIRT and MyStore query sets and some test data. This makes it very easy to test if the DB Connector is up and running when your installation is complete.

When you complete the Installation instructions then follow the Connector Configuration Instructions - detailed steps to integrate the connector with your database.

Cloud customers must also verify connector connectivity to the frevvo Cloud Server.

        The Standalone Database Connector bundle includes the files shown in the image:

        Note the files in the database-connector-2.5.x directory that are used to manage the Database Connector as services on *nix and Windows operating systems: These files should be run as an administrator.

        • Install-Service.bat - installs the Database Connector on a Windows system as a service named frevvo Database Connector.

        • Uninstall-service.bat - uninstalls the frevvo Database Connector on a Windows operating system

        • Start-DB Connector-Service.bat - starts the frevvo Database Connector on a Windows operating system

        • Start-DBConnector.sh - starts the frevvo Database Connector as a *nix console instance.

        • Restart-DBConnector-Service.bat - restarts the frevvo Database Connector on a Windows operating system

        • Restart-DBConnector.sh - restarts the frevvo Database Connector as a *nix console instance.

        • Stop-DBConnector-Service.bat - stops the frevvo Database Connector on a Windows operating system.

        • Stop-DbConnector.sh - stops the frevvo Database Connector *nix console instance.



    • Method 3: for *nix OS
      1. Execute the  DB Connector.sh shell script for Unix/Linux operating systems.
    • Method 4: for Linux
      1. The Database Connector can also run as a service under Linux systemd

    It is possible to manage the Database Connector using systemd ‘service’ scripts.

    1. Copy the sample service file located in /bin/dbconnector.service to /etc/systemd/system
    2. Review its contents and
    3. Make sure it is executable.

    You can now use systemd to manage the dbconnector service:

    • systemctl start dbconnector.service

    • systemctl stop dbconnector.service

    • systemctl restart dbconnector.service

    • systemctl status dbconnector.service

    To flag the service to start automatically on system boot use the following command:

    Code Block
    systemctl enable dbconnector.service

    Consult the service unit configuration page for more details.


  5. Browse http://<host>:<port>/database/status - Note the standalone connector defaults to port 8081.
  6. If the status returns failures or disabled Connector Test failed then:
    1. Review the previous installation steps
    2. See starting and testing the connector installation for more detailed instructions and common problems. 
  7. When the status returns Passed for each queryset, your installation is complete.
  8. Cloud customers must also verify connector connectivity to the frevvo Cloud Server.
  9. Follow the Connector Configuration Instructions with the detailed steps to integrate the connector with your database.

  5. Start the Insight server, then start frevvo.

  6. Test the connector installation by copying this URL directly into your browser:
    http://localhost:8082/database/status
    After performing these steps you will have: successfully installed the frevvo database connector and retrieved data from the built-in test database
  7. Log into frevvo as the superuser (admin@d, admin). Create a tenant.
  8. Create a designer user in the tenant
  9. Download the Database Connector Project, then upload it to your designer user. This project includes some example forms that demonstrate the power of the Database Connector using built-in databases.
