Server and Network Problems

Updated: 2012-11-01

If MeOS access to the server is broken you will get a notification. MeOS will allow you to continue to work with the competition or to readout cards, and will try to continue restoring the database connection in the background.

When the database connection is restored, all changes you made since it was lost are automatically transferred to the server, and will be available to other MeOS users. In conclusion: it is possible to handle a brief power failure or restart of the server without interrupting the work of attached computers.
Note
The automatic recovery should be used with some caution, and only if you believe the server will be restored. If you are unable to restore the server, changes will be lost.
The command Disconnect Server on the page with server settings, makes MeOS stop trying to reconnect, and continue to work locally. You can use the log files created when reading out cards, to manually transfer data to a main computer, in case of a permanent network failure, see Automatic Backup and Restoration.

If you get database errors when trying to open a competition, you can try to repair the database. Make sure that no one else is working with the database. We recommend disconnecting the network cables or making the network router or switch powerless to be certain. Then click Repair Selected Competition on the database page in MeOS (the one MeOS instance that is still connected to the server). If this command succeeds, you should be able to open the competition again, and restore the other clients.

If repairing does not work or help, you need to restore the last backup (see Automatic Backup and Restoration) and upload it to the server as a new competition. Make sure all clients connect to the new competition.
