How to enable IBM Rational DOORS Database Server logging

Technote (FAQ)


How do you enable IBM Rational DOORS Database logging?


None of the DOORS administration tools have a logging option.


IBM Rational DOORS logging has 6 levels; Level 1 is the most terse and 6 the most verbose. Here are the log level details:

  • Level 1: Report connections, disconnections, and problem packets.
  • Level 2: Report connections, disconnections, and packet types.
  • Level 3: As Level 2, plus packet arguments (compact format).
  • Level 4: As Level 3, but with packet arguments in verbose format.
  • Level 5: Only logs data cache operations.
  • Level 6: Logs messages as in Level 4 plus Level 5.

You may also check login_history file to check log in history under $DOORSHOME$\data\v6data\logs (example: C:\Program Files\IBM\Rational\DOORS\9.x\data\v6data\logs)

To help identify an unspecified error you can start logging at level 6 to capture all activity.

Once database logging has been enabled and you reproduce the behavior send the generated log file to Rational Client Support.

IMPORTANT: Ensure you disable database logging after the issue has been reproduced since this overhead may impact the performance.

For Microsoft Windows:


This solution contains information about modifying the system registry. Before making any modifications to the Microsoft Registry Editor, it is strongly recommended that you make a backup of the existing registry. For more information describing how to back up the registry, refer to Microsoft Knowledge Base article 256986

  1. Click Start > Run > type regedit to open the registry editor on the server

  2. Navigate to the following key:

    for 32-bit Operating System:

    for 64-bit Operating System:

  3. Create a new string value called logfile

  4. Modify the string value and set its data value to the log file location
    For example  c:\doorslog.txt

  5. Create a new string value called loglevel

  6. Modify the string value and set its data value to: 6

  7. Restart the Rational DOORS Database Server

    Note: All users need to be logged out of DOORS before attempting to restart the server

For UNIX and Linux:

Start the DOORS Database Server with the following options:

doorsd -p "port number" -L "log level" -l "path to log file"

Where <port number> is the DOORS Database port number and the path to the log file includes the file name.

For example: doorsd -p 36677 -L 6 -l /usr1/logs/DOORSusers.log
