Environment

Retain Unified Archiving 3.5.1 to 4.7

Situation

If you are experiencing an error during the first Setup of Retain when using a Mysql-Database:

"An error occurred configuring database: Failure to acquire Enterprise DB Connection."

Resolution

You 've missed installing the MySQL-Connector-J library.
You can find it here: "https://dev.mysql.com/downloads/connector/j/"

After you've downloaded and unpacked the mysql-connector-java-5.1.X.jar you should copy the file to the following directories:

  • /opt/beginfinite/retain/RetainServer/WEB-INF/lib/
  • /opt/beginfinite/retain/RetainStatsServer/WEB-INF/lib/
  • /opt/beginfinite/retain/RetainWorker/WEB-INF/lib/

Next the tomcat-user needs to have group access to those files.

Therefore you can either run

$ chown tomcat:www <filename>

or do this via the Graphical User interface and Assign the owner to tomcat and the group to WWW.

After you've done these steps restart the retain service with:

 $ rcretain-tomcat7 restart

The Connection to the Database should be working now.
