A new script utility is available to assist with installations and upgrades of Zoomdata. This new utility replaces the current installer script (now deprecated) used for previous Zoomdata versions. Contact Zoomdata Technical Support for details.
SSL/TLS support for the Zoomdata Oracle connector has been confirmed with this release and requires an upgrade of the Oracle JDBC driver used by the Zoomdata Oracle connector. Be sure you use the new Oracle JDBC driver when you set up Zoomdata's Oracle connector. See Adding a JDBC Driver and Managing the Oracle Connector.
In addition, the updated Oracle JDBC driver requires additional setup steps if you need to use Zoomdata's Oracle connector to connect to tables that use the XML data type. For more information, see Managing the Oracle Connector.
Finally, Zoomdata now supports Oracle versions up to 18.3.
This release allows you to limit the list of available collections in a Teradata data store to collections from a specific schema specified in the Teradata JDBC URL. The Teradata JDBC URL
database property can now be used to limit the list of available schemas as well as the list of available collections to collections from the schema. Work with your Teradata database administrator before you use this property. See Managing the Teradata Connector.
This release introduces connector load balancing. Using a new Consul service registration model, several instances of the same connector can be registered simultaneously and Zoomdata can distribute queries among them in a round-robin fashion. This ensures that you get uninterrupted service, even when a connector instance goes down. The unique connector server URLs for started connector instances appear in the list of connector servers on the Manage Connector Services page.
All Zoomdata 4.1 connectors use this new service registration model. However, the new model is not fully compatible with earlier versions of Zoomdata. Special configuration steps must be performed if you want to:
Use a Zoomdata 4.1 connector with an earlier version of Zoomdata.
Use a Zoomdata 3.1 (or earlier) connector with Zoomdata 4.1 (or later).
Zoomdata 3.2 to 4.0 connectors are fully compatible with Zoomdata 4.1.
See Migrating Connectors for Other Zoomdata Versions for more information.
This release introduces a new privilege for users in a group called Can Administer Groups. This privilege lets group members:
- Add or remove group definitions
- Assign and remove users in a group definition
- Restrict the ability to read, edit, and delete data source configurations by group members
- Restrict the data source configurations available to the group
- Authorize users in the group to perform specific Zoomdata functions.
|This privilege does not allow group members to add or otherwise maintain user definitions.|
SSL/TSL support for the Oracle connector has been confirmed in this release.
If you already have permissions to access a data source, you can now refresh it using Zoomdata's REST API without switching accounts.
The logout problem when SAML authentication is used has been resolved.
The version of jQuery UI packaged with Zoomdata has been upgraded to address a jQuery UI application vulnerability.
User authentication is now required to access
/zoomdata/js/zoomdata-web.jsvia a web browser.
Auto-provisioned SAML users are no longer granted user roles instead of group-only roles.
Manually upgrading Zoomdata 4.1 or later no longer provides the Java Runtime Environment (JRE) needed for Zoomdata to start. Make sure you have Java 8 (1.8.0_131) or later installed before you manually install or manually upgrade to Zoomdata 4.1 or later. If you do not, Zoomdata will not start.
An option to install OpenJDK is included in the installation and upgrade scripts provided by Zoomdata. If you skip this option or if you install or upgrade the product manually, make sure that Java 8 (or later) is installed.
