CAWIS stands for Continuing Airworthiness Web Information System

...


The following section, “General troubleshooting” provides an overview of the steps to take when investigating an issue with the CAWIS MDM Application. Links with more in-depth details about how issues have been resolved to-date, are also provided.


General troubleshooting

Contact list for the contacts mentioned below

Current update, Jan 2023 regarding who to contact:

...

  1. Check the log file for the environment that is affected. The current The current log file is called “output.log”. They are located in the UNC locations listed in the Environment access information at the beginning of this document. The log files are automatically rotated when they hit a certain size. You may need to look in the “logs” folder if the problem happened a while ago.

    The MDM inbox/account is called DNRENAC. Currently, it’s password is auto updated every 80 days, by the MDM process on the script server at \\ncrws548\scripts\CivAv\CAWIS-MDM. Again, log files in the “Log” directory will tell you exactly when the process began failing

  2. If there’s no logs being generated => the task isn’t running
    For support on the web application contact the web group for diagnostic or server restart.

    For a production issue with the web application, open an ORION ticket to the attention of the web server group so that they can work on and document the issue.

  3. If the process seems to be looping the same messages => One of the thread in stuck:

    • You can wait for the deadlock-prevention timer (2hr) to kick in.

    • OR contact the group responsible for the server to kill the task.

      Per Marcin on Jan 27, 2023: “the deadlock issues we had we back in 2020 and for those you need to contact Oracle dba group.”

  4. If there's a message like “Application is disabled due to database configuration.“ => The application is disabled

    1. In the TR47 table in the CAWIS database, set the configuration called “MDM - APPLICATION ENABLE” to “true”.

  5. If there’s a message like “exchange server is unreachable.“ => The email account might be locked.

    1. Open a command prompt and type “net user DNRENAC /domain“. In the response, you should get something like below:

      If the line “Account active” says “Locked” or “No”, contact the Service Desk for them to reactivate the account. To-date, most recently in Jan 2023, Robert Lang and Muhammad Duhabei Dehaibi assisted with this.

    2. The password for DNRENAC is in PINS. It is set to “never expire”. If the password does get changed for any reason the database table TR47_CAWIS_GENERAL_PROPS also needs to be updated. See also:
