Please try your operation later as the resource was busy

[adman666]

Hi,

We are having problems since upgrading to MGOS2.
Our app creates FeatureSources on the fly as a user needs them:
featureService.CreateFeatureSource(markupSdfResId, sdfParams)

and then they can draw on the layer and the Feature Source is updated:
featureService.UpdateFeatures(resourceIdentifier, markupCommands, False)

This was all good under 1.2. The Resources are not ReadOnly. When we execute the code now we get this error:

<2008-03-31T16:49:32> Administrator
 Error: Please try your operation later as the resource was busy: Library://AEMSDB/Actions/487/Data/11504.FeatureSource

We have never seen this before upgrading to 2.0. Do we need to set some extra permissions somewhere or something like that?

Any ideas would be most appreciated.

Thanks.

Are you closing your featureReader? show us some more code :)

Also, you probably want to be using session resources rather than
library resources

I am getting this message too.  I am closing my feature reader and disposing of it.
The problem happens when the user adds features to one of the feature sources named "Jobs".  We use our map primarily to track where we have worked, and users need to be able to add jobs to the map.  Sometimes it works, other times it harrasses me about the resource being busy.  I would have to use the library resource because the changes need to show up in everyones map.

Am i missing something here?  is there a way to possibly check if the resource is busy and force it to not be?

[Bruce Dechant]

Mark,

The error you see below is typically a result of the resource still being used by someone else. However, if a feature reader is not closed and you try to do something with the same resource (update) it can report that it is in use still and therefore busy.

Since you are closing your feature reader I suspect the problem is most likely a defect if you are the only one that is using it.

What provider is this happening with? Is this easily reproduced?
If you could create a track ticket for this and include as much information as possible for someone to investigate the issue that would be great.

Thanks,
Bruce

I'm a little confused here.
You make it sound as if only one person can update the library resource (in this case a .sdf file) at a time.  I thought that multiple people could interact with the file making changes at the same time more like a database.
I get this error about every other time i try to add a feature to my feature source.  There is a lot of code that could be suspect, i will try to isolate the error this weekend and if it's not my code i will submit a trac ticket.

Mark,

The access is similar to a database, except is dependent on what the underlying provider supports. In the SDF case I believe this is multiple reads and single write is supported.

i'm using MGOS2.0 and got the same error when trying to update the feature source i just had read from, by the feature service's UpdateFeature method. I closed the feature reader and call the delete method of MgFeatureReader before. Neither the Close nor the delete makes any difference, the error stays the same:

MgFeatureReader locReader = featureService.SelectFeatures(featureId ....
locReader.ReadNext()
....
locReader.Close();
locReader.delete();

featureService.UpdateFeatures(featureId, cmdCollection, false);


did you found any solution to your issue - probably the same like i'm looking for,

[Mark Pendergraft]

I have not found a solution to the issue, it's a bug in 2.0 and there is
already a trac ticket for it(http://trac.osgeo.org/mapguide/ticket/524)

The solution I have come up with, is to roll back my map to 1.2.
Sorry for the bad news
-Mark Pendergraft.

Try changing the server settings.  In the IIS settings, open up the properties for the default web site and go to the HTTP headers tab.  Enable Content Expiration, and set it to expire immediately.  On the Web Site tab, please also disable the "HTTP Keep-Alives Enabled" box.  Restart the MapGuide service.  This worked for me.

[George McLean]

I am also seeing this problem Apache-PHP running on XP SP2 with MG 2.0.

I am confident I am closing the feature reader before calling the
update. At this point this is the only thing keeping me from putting MG
2.0 into production. I saw a comment that suggested setting the content
expiration to immediate. The suggestion was from an IIS user. So far I
have not figured out how to set this in Apache in Windows.

Any suggestions?

Thanks

George McLean
