[mapguide-users] SDF load problems

Wed Mar 22 18:43:20 EST 2006

I haven't tried it.  I'm sure it would work fine, but it seems like an awful
lot of work to take a Shape file and copy it from one network location to
another (the repository)......... And what about those 1 GB Shape files?
It's a lot of package and data shuffling to keep your repository data in
synch with the source data.  I would like to be able to point the repository
location to reference the source data in my chosen network location.  Sort
of like MapGuide 6.5 UDL files, but you could still retain the managed data
aspect.  

In the case of converting your source to SDF+, some of us would rather use
FME scripts to update the SDF files in the repository.  This would be OK if
there was an easy way to know where in the repository that feature source is
created when it is initially defined.

Regarding "Many of us will want to update our data through external
processes", has anyone tried to write some code which does the following?

1)       Use the Studio Load API to create the package locally from the
latest source data.

2)       Copy the resulting package file into the Package directory on the
server.

3)       Use the MGOS Admin service API to apply this updated package.

Would this meet most of your needs to update the source flat file data
wrapped by FeatureSource resources?

Thanks,

Ed

Sorry, I should have clarified that my rant pertains to flat files only.
Database connections will be direct to their source.

Wow.  So you're saying that if and when a provider for Oracle Spatial comes
along, we won't be able to define the connection to the database and have
the data come directly from that connection?   It basically dumps the data
(that point in time) into a repository that resides in on the MG server?   

Can someone from Autodesk comment on this?

This is where using a managed data structure is a detriment, in my opinion.
Many of us will want to update our data through external processes and there
is no easy way to just copy files into the repository or point to an
existing network location.  I think this is going to become a much bigger
problem as people put these systems into production and realize that they
have to "load" their data into repositories.  It's also going to be a large
problem for keeping data up to date with ongoing system maintenance.
Scheduled process are going to be a necessity to ensure that the data in the
repository is in synch with the source data.  And, in the case of large
source datasets, the entire dataset will have to be reloaded as there is no
incremental update method. 

I believe (but have not yet done this) that the Studio API is going to have
to be used to load these resources, not the server API.

Ahhh. I see, I misunderstood the use of "Packages" and didn't think too look
there.   Thank you. It is working fine now. 

I have noticed that imported SDFs are processed (into SDF v3, I believe). Is
it currently possible to import SDF data sources into the repository without
using Studio at all, just using the server API? Is it possible to create
your own Packages using the server API?  I would be interested in doing this
for our migration tools.

It looks like it's too big.  You'll probably have to "Package" the data and
upload it to the server manually, then bring it in via the site Admin web
app.

I am trying to load a 225 MB SDF file using MapGuide studio. I have tried
any number of different options and they all seem to fail. The process
crunches for a while, and then says "Communicating with server" and the
progress bars fills to 100% .  Eventually, an error dialog is popped that
says "Unable to complete request to site. Connection lost". 

The apache logs showed the following. None of the other logs reported
anything of interest that I could see. 

[Wed Mar 22 13:33:54 2006] [warn] FastCGI: (dynamic) server "C:/Program

Anyone have any ideas about what is going on?
