Q: Help! I upgraded to Tower Enterprise 22.2.0 and now my database connection is failing.

Tower Enterprise 22.2.0 introduced a breaking change whereby the TOWER_DB_DRIVER is now required to be org.mariadb.jdbc.Driver.

Clients who use Amazon Aurora as their database solution may encounter a java.sql.SQLNonTransientConnectionException: ... could not load system variables error, likely due to a known error tracked within the MariaDB project.

Please modify Tower Enterprise configuration as follows to try resolving the problem:

  1. Ensure your TOWER_DB_DRIVER uses the specified MariaDB URI.
  2. Modify your TOWER_DB_URL to: TOWER_DB_URL=jdbc:mysql://YOUR_DOMAIN:YOUR_PORT/YOUR_TOWER_DB?usePipelineAuth=false&useBatchMultiSend=false
