<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>Are the markups
permanent or temporary: this may have a big impact on the approach you can
take? If temporary they should be created in the Session Repository which
should at least avoid whatever may be causing corruption of the main
repository. If users are creating their own markups do they need to share the
same resource? Why can’t they each have their own temporary session based
SDF? This will probably avoid any corruption.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>The fact that you are
trying to delete them suggests they are somewhat temporary. If they were
created based on the session id then when the session expires you might create
a process to delete the expired ones. Just a thought.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>We have encountered a critical
flaw with MapGuide in particular the undocumented use of the SDF format to
create multi user based red lines – the default samples all highlight
this is the approach. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>As an example, we created an
application that allows users to each create, modify and display redlines from
the same SDF file (as per the sample). We were recently informed by
Autodesk that the SDF format is not meant to serve as a mutli-user creation
format (which is an undocumented feature by the way!). <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>During our testing when multiple
users create redlines at the same time – the repository become corrupt
and forces us restore the previous MapGuide package (does anyone know how to
automate the deletion of SDF files in the repository without knowing the names
of the repository names – i.e. the users create redlines and we do not
know the repository names)<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>The big ask:<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Does anyone have any experience
creating redlines in anything other than SDF, notable SQL Server 2005, GML,
KML, etc (we are not an Oracle or PostGIS shop) or any other work arounds we
would greatly appreciated we are at a loss and in a time crunch.<o:p></o:p></span></p>
