[mapguide-users] Site corrupt - MG Server fails to start

[Brad Nesom]

Is there a service or application that could be checked to see if the
cleanup is still running or completed?

The files might not actually be corrupt, but may have not been closed
properly (example: due to power outage). When the server starts it tries to
"clean up" the repositories using the generated log files. Under certain
circumstances this can take longer then the Windows Service Control Manager
allows for a service starting up. The thing to do in this case is to not run
the server as a service and instead run it interactively as an application
to give the server time to cleanup the repository. Once the repository has
been cleaned up you can stop the server application and restart it as a
service. Note: that you should not have to do this under normal operating
conditions.

Good cautionary tale.

 

If anyone is not backing up their repositories, they should strongly
consider it.  I haven't seen any problems yet, but the repositories are
file-based and are subject to corruption in the case of interrupted writes,
etc.

 

There is a RepositoryAdmin directory in the Server installation that
contains some utilities for doing this, and instructions.  You can find a
copy of the isntructions here:

ver/RepositoryAdmin/MgOpenSourceRepositoryAdmin.pdf

 

Hmm.  It would be nice if we could leverage an RDBMS data store to store the
repository info.  This would kinda break the managed data idea, but it would
eliminate the load balancing problems around session access.  I don't really
like storing my data with the site configuration info anyway :)

I have no idea how this happened, but it is rather disconcerting. Luckily it
was only the Site data that was a problem and that my Library seems to be
fine. Otherwise I would be reaching into my backups to restore from.
