This article outlines the process of enabling debug logging flags in the log4j2.properties file for TIBCO Data Virtualization. This is a crucial step in troubleshooting and diagnosing issues, as it allows for capturing more detailed log entries, aiding in tracking system behavior effectively.

This article provides details on how to enable debug flags within the log4j2.properties file of TIBCO Data Virtualization.

All Supported Environments

In this example, we will be discussing the steps to turn on cache refresh debug from the log4j2.properties file. Below are the steps to enable debugging:
(1)   Back up the file <TDV_SERVER>/conf/server/log4j2.properties on the TIBCO Data Virtualization Server.
(2)   Append the following lines to the 'log4j2.properties' file or uncomment the existing lines, which will enable debug logging specifically for cache refresh:
(3)  To activate the debug trace, you should restart the TDV Server. However, if you prefer not to restart it, you can use an alternative approach:

• Navigate to Studio > Administration > Configuration > Server > Configuration > Debugging > Debug Output Enabled.
• Change the value to “True”.
• Click “Apply” but don’t close the window.
• Immediately change the value back to “False”.
• Click “Apply” and close the window.

(4)  Once debugging is enabled, you can proceed to reproduce the issue you're troubleshooting. The debug entries will be reflected in the 'cs_server.log' file. 
      Sample Entries: (5) To disable debug logging, comment the .level=DEBUG lines in the log4j2.properties / if new lines were added, then remove them. Carry out Step (3) once more to reload the log4j2 file to disable debug.
