Problem

For stability reasons, certain engines -including Proactive DLP- are pinned to a known good version in Email Gateway Security bundle editions (for details about editions see the Editions section in 1. Licensing).

Engines -e.g. Proactive DLP- usually use a database that contains engine relevant data that may change frequently. To keep the frequently changing data up-to-date, the databases are not pinned and updated automatically by the underlying Core component.

In case of a new installation, there is still no database in the system, and the latest version gets automatically downloaded. As the engine may be pinned to an old version, but the latest database is downloaded, there may be incompatibility between the engine and the database, and the engine won’t work.

Example

In the example below the situation can be observed in Email Gateway Security, when due to engine and database version incompatibility the Proactive DLP engine won’t work.

The same situation on the bundled Core side.

The engine version 2.3.0 is incompatible with the database version, that was released for Proactive DLP 2.5.0.

Clicking the Proactive DLP engine’s entry the status INACTIVE can be observed due to the engine and database incompatibility.

Solution

Resolution

The compatible Proactive DLP database must be deployed manually in the bundled Core. For details and instructions see the Manual updates section in https://onlinehelp.opswat.com/corev4/7.2.2._Modules.html.
