There are different logfiles for the Standalone and tomcat bundle installations.

Standalone mode

There are four logfiles in <dbThe 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-2.5.x\logsDD.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

   .

   database-connector.YYYY-MM-DD.log - This is the main logfile all output.

Tomcat bundle

The database connector writes all output to a single logfile <frevvo-home>\tomcat\logs\database-connector.YYYY-MM-DD.log

Turning on DEBUG level logging

1. Stop if you are using the tomcat bundle or the Standalone database connectorDatabase 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.connector.database=DEBUG

4. Save the file
5. Restart the connectorthe Standalone Database Connector service or if you are using the tomcat bundle.
