To use Looker with DataVirtuality, you will need to configure a DataVirtuality driver. These instructions describe that process, assuming use of a startup script similar to the examples provided on the looker-open-source GitHub page.
You will need to acquire a DataVirtuality driver JAR, include it as part of the startup process, and add an option to tell Looker to access it.
Encrypting network traffic
It is a best practice to encrypt network traffic between the Looker application and your database. Consider one of the options described on the Enabling secure database access documentation page.
Installing the DataVirtuality JDBC driver
Follow the steps on the Unpackaged JDBC drivers documentation page using the following values:
driver symbol: datavirtuality
driver entry:
- name: datavirtuality
dir_name: datavirtuality
module_path: com.datavirtuality.dv.jdbc.Driver
Creating the Looker connection to your database
Follow these steps to create the connection from Looker to your database:
- In the Admin section of Looker, select Connections, and then click Add Connection.
Select DataVirtuality from the Dialect drop-down menu.
Fill out the connection details. The majority of the settings are common to most database dialects. See the Connecting Looker to your database documentation page for information.
To verify that the connection is successful, click Test. See the Testing database connectivity documentation page for troubleshooting information.
To save these settings, click Connect.
