The Database Connector logfile is located in <frevvo-home>\tomcat\logs for the tomcat bundle and in <db-home>\database-connector-X.X.X\logs directory for the Standalone bundle. X.X.X is the version of the Database Connector. It is named database-connector.YYYY-MM-DD.log

In standalone mode, you will see three additional logfiles.

  1. DbConnector.err.log - currently empty.
  2. DbConnector.out.log - logs the database connector version.

  3. DbConnector.wrapper.log - empty unless the database connector is running as a servers. Logs starts/stops date/time.

Turning on DEBUG level logging

  1. Stop if you are using the tomcat bundle or the Database Connector service if you are using the Standalone bundle.
  2. Edit the:
    1. Standalone bundle - <db-home>\database-connector-DBC version number\config\dbconnector.properties file
    2. Tomcat bundle - <frevvo-home>/tomcat/conf/dbconnector.properties file.

  3. Add the following line.

    Code Block
     logging.level.com.frevvo.connectorconnectors.database=DEBUG
  4. Save the file
  5. Restart the Standalone Database Connector service or if you are using the tomcat bundle.
