Enable Detailed Logging in Domino


Topic Last Modified: 2006-09-14

It is difficult to locate problems that are encountered when Lotus Notes users try to access free/busy information for Exchange users because most of the processes are handled by tasks that are running on the Lotus Domino server. It might be a good idea to enable debug logging for the Lotus Domino server to collect helpful troubleshooting information.

To enable debug logging for calendar processes on the Lotus Domino server
  1. Stop the Lotus Domino server by issuing a Quit command at the Domino server console.

  2. Edit the Notes.ini file on the Lotus Domino server. By default, this file resides in the C:\Lotus\Domino directory.

  3. Add the following line to the end of the Notes.ini file: DEBUG_SCHED_ALL=1

  4. Save the Notes.ini file and restart the Lotus Domino server.

After you restart the Lotus Domino server, all Lotus Notes Calendar Connector and Exchange Calendar Connector activities are reported to the server console and the server Log database (log.nsf).

Additionally, you can save the information in an output file. To save the information, you must the set the DEBUG_OUTFILE variable in the server's Notes.ini file. For example, you can type the following line to write all console messages to a file named output.txt in the root directory:


You must restart the Lotus Domino server for the changes to take effect. After the server reinitializes, all messages and debugging information are written to this file. Logging this information can involve a high volume of data. Debugging affects the performance of your Lotus Domino server, so specify the debugging parameters only in a troubleshooting situation.
