This article explains how to differentiate between the MariaDB/SQL version of the GRAVITY server app and the Oracle version.
One you downloaded the jar-file, check the ending of the name:
If the file name ends with an 'o', then this will be the jar-file for the Oracle database
If the file name contains only the version number, then tis jar-file is intended for MariaDB/SQL databases
If you downloaded the wrong version please raise a ticket and we send you a new link to the correct version. The download links, we send out with the release information, have an expiration date. Normaly we set the link expiration to seven days.
