Re: [mapguide-users] RenderMap: MgOutOfMemoryException
I can definitely confirm that rendering large map images via the API is definitely memory intensive on the Mapguide site. Then when you get the image out into .NET, you might even go into deeper problems with the way the Large Object Heap collection works and so on. You can end up with pretty massive amounts of memory in there if your code is running in a service or something where memory collection can be more harduous. You could look into creating smaller tiles and stiching them up for the resulting image. It might keep memory usage under control. Perhaps limiting the map images to boxes of 2048x2048 and then tiling them back into a single image. It does require a bit of math and finagling, but definitely worth the trouble. There might also be some issues on depending on what kind of app this code runs. If it's a web app, if 2-3 users end up asking for the same large image within a similar timespan, it could get crazy. So that's something that generating smaller tiles might help out with. Hope the idea helps out! -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] Mapguide 3.1.2 Hangs
Did you update your binaries for Mapguide when deploying against 3.1.2? AIMS 2017's dlls are for Mapguide 3.1.1.4601, which isn't the same version. Sometimes I've seen some issues when using the wrong version of the Mapguide API dlls.

Re: [mapguide-users] Mapguide 3.1.2 Hangs
Might be worth looking into making sure you actually call Dispose on the MgService you create. Also depending on what else you're doing, I'm guessing you might have some MgByteReader and the likes that might not get closed and disposed. Mapguide also isn't "hung" when the pink map shows up, typically Something goes wrong with the application pool in IIS and it stops properly communicating with the Mapguide service. Typically a restart of the app pool brings everything back fine. Which leads me to think the issue might be with proper memory management. As far as I am aware/remember, Mapguide's API in .NET isn't really pure .NET and is actually a SWIG wrapper over the C++ COM API. So some of the classes are VERY SENSITIVE about getting properly disposed and closed in your code. Your code could be making your application pool run out of assignable object references from the C++ API. So all in all, try not to declare any "Mg" classes you don't intend to use and make sure that when you do, you dispose them. The most important ones are any of the Mg*Reader classes, for reading features, resources, etc. Likewise for MgService classes.

Re: [mapguide-users] MapGuide Open Source 4.0 Preview 1 available
I understand Mapguide might be useful for some low-end deployment that still run on 32-bit hardware, but is that common enough to warrant making it a much harder time on the already hard working devs of Mapguide?

Re: [mapguide-users] Memory Leak in Java
Hi, I'm no Java expert, but I feel it could be a similar issue that you may face with .NET and Large Heap Objects. With the size of the byte array you are creating, 1024x1024, you might be overruning the size of the level 1 generation for the Garbage Collector and end up putting your data in a later generation that doesn't get collected very often. So when I do things in .NET with MgReaders that can get sizeable, I do set a hard cap at 4096 bytes being read per iterations and they don't end up on the LOH. Looking at your code, you potentially create 4 1MB large objects every round. So those likely end up somewhere in your memory stack that the JVM garbage collector doesn't clean up very quickly. I did some quick Google searches about it and it seems a fairly common topic when it comes to Java and object generation. I think it might be worth it to do a quick search to optimize on that front. Hopefully someone more knowledgeable about Java can chime in, but I feel it might be a worthwhile area to look into while waiting for a reply!

Re: [mapguide-users] Coordinate transformation from CSRS to LL84

There is an example of how to do it inside of Autodesk Civil 3D here: https://blogs.rand.com/civil/2013/10/imaginit-utilities-for-civil-3d-coordinate-systems.html I suppose the question becomes how to use the parameter for custom projection libraries that is inside the serverconfig.ini ?

[mapguide-users] MapAgent error tracking
Hi, I was wondering if there are any logging tools I might be missing specifically for when the MapAgent (in IIS) starts misbehaving. We call it the dreaded pink map of death. Basically it stops returning images and returns http status of 559 out of the blue. Only a restart of the application pool in IIS can make things go back to normal. The error return is an unexpected one, therefore it offers zero input into what went wrong. Is there any way to automatically recycle the application pool if an http 559 error occurs? It doesn't track any "stateful" element, therefore recycling it should typically put things back on its feet. Anyone have any experience setting something up?

Re: [mapguide-users] Number of Active Sessions
Hi, If you use Maestro, which I am assuming you do, in the Tools menu you have a "Server Status" tool which does show an Active Connections property. The totals are, as you said, since the last server restart. So that can still give you some live information about what is going on. In your specific case, it might be worthwhile to use the map profiler in the administrator to check if perhaps a very specific layer of yours is slow, which tends to start queuing up operations and slowly degrading performances.

Re: [mapguide-users] MGOS 3.1.1 - SQL Spatial Layers - Cannot select point layers by click on it or see the tooltip
Hi Jose, The one thing I can think of is if the point layer stores data in geography columns versus geometry. That is one of the reason I have had issues with Mapguide on SQL Server. Basically the directionality of the selection matters and it has to be counter-clockwise. When the selection is drawn clockwise, it appears to count as the "hole" in a "donut" polygon. Sorry for the weird description, it'd be easier to draw it out! So if you use a geometry type, that shouldn't be a problem. The second possible issue would be not having a properly defined primary key, such as going against a view. That is one way SQL Server can prove a bit difficult to deal with in Mapguide sometimes. However, since selection works sometimes in your case, that is likely not the reason. Hopefully it's simply a matter of switching the data type on your spatial column.

Re: [mapguide-users] MapGuide (actually FDO) 64-bit Linux blockers
While OGR is a neat provider, we did experience certain issues with it that makes me feel that for some data sources it might not be the best solution. We would basically get unreliable results when doing queries against it, which isn't really good when users are trying to run queries on their data for decision-making purposes. With OGR on MapInfo (TAB) we would get bad results when applying both a spatial filter and attribute filter at the same time. On a MgFeatureQueryOptions we would call up SetSpatialFilter and then SetFilter and we would get invalid results. The same code that would do the equivalent of the SetFilter on a C# DataTable would work just fine. Although if we do start focusing more on making sure the OGR provider is tested and validated under multiple spatial data types. I do wonder if using an abstraction layer (OGR) on top of another abstraction layer (FDO), we might have a harder time debugging issues and getting better performances. I don't have any metrics at the moment, but I could likely work on some if it's something that could be useful. -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users

Would this be a Linux only issue or something else? I looked at what we install and it's the content of the gdal-1.10-msvc2012-x64.zip and I'm fairly certain we got it off of the OSGEO website. Looking at what we deploy, it's the regular 3.1.0.9064 build on 64-bits on Windows. So it really seems like we're as vanilla as it comes and doing the steps in the initial link works just fine. Honestly, outside of forgetting to set the GDAL_DRIVER_PATH environment variable, it was never an issue for us.

Re: [mapguide-users] 30 seconds delay after creating +/-100 CreateRuntimeMap calls
I do believe you are leaking 1 MgByteReader per call. Here is the definition of the function call: public virtual *MgByteReader* CreateRuntimeMap(MgResourceIdentifier mapDefinition, string sessionId, int requestedFeatures, int iconsPerScaleRange); It returns a MgByteReader. I strongly recommend putting it in a variable and calling Dispose() directly on it. Odds are you are holding on to a bunch of MgByteReader and the delay is the time the garbage collector takes to manually dispose those objects. My second recommendation would be to maybe not use CreateRuntimeMap. You are not using the returned map definition whatsoever. You may as well just create an MgMap and MgSelection directly and avoid some unecessary processing? CreateRuntimeMap is useful when you want to have more information about the map, including having Base64 icons for layers for a legend type control. It doesn't look like this is the case for you.

[mapguide-users] SelectFeatures vs SelectAggregate on SDF FeatureSource
Hi, So I'm not sure if this issue is also present on Mapguide 2.2, as I'm deploying an application using Mapguide 2011 Update 1. Still, I'm stupid amounts of baffled by this issue. Nothing works right using the SDF provider. Any queries without a geometry field made with SelectFeatures will not return any records. No errors occur, but no records are ever returned. While the exact same code, using the SelectAggregate function will return the desired records. Is this a new behavior that is to be expected when running a query without adding the geometry column to the query? Or is this an issue specific to the SDF provider? I've already deployed an application that uses King.Oracle as the provider and it didn't seem to have this side effect. Lets just say that this breaks a whole slew of code in both Fusion or any custom code that was written to hit up SDF file for data. Hopefully it's just something that is broken inside of the provider and can somehow be fixed. Any idea if this is something different in Mapguide or an issue I need to write up on the SDF provider?

Re: [mapguide-users] MapGuide vs Google maps
This is a bit like comparing apples and oranges. The two are very different kind of technologies. Google Maps basically renders maps using pre-generated tiles. It has some good API for overlaying KML data, but that data will be rendered client-side by the user's browser so any excessive amounts of data will bring the whole thing to a screeching halt. Mapguide renders map images that are unique per session. Therefore, it has the ability to turn layers on or off, to personalise the look of a map layer at any time during the session and allow for rendering of custom data generated server-side. The dynamic nature of Mapguide allows you to generate thematics for your layers of data (like say, different colors for traffic levels on a street) and every time Mapguide generates an image of your map, the streets will be colored depending on the current values for the traffic levels. Thematics on layers is something that is very widely used in GIS. There's also the fun thing of mixing both technologies together. Using OpenLayers (www.openlayers.org), it is possible to overlay Google Maps data and Mapguide data. I do believe the very latest version of the Fusion Viewer enables dev. to create a viewer that does this as well. This can be very useful if you want to use Google's basemap and overlay some geometries from your own Mapguide server. You basically get Google's look and feel, plus its speed, along with your data. Keep in mind if your site isn't widely available to the public (no login, non-Intranet, etc), using Google Maps requires a license and there are fees attached to it.

RE: [mapguide-users] 2.1 Beta (Fusion) Problems
The Firefox issue is fairly straightforward to fix, except for my lack of
understanding of the actual cause of the issue.
In ApplicationDefinition.js, the method getAppDef(xhr) needs to be changed
to be like this:
getAppDef: function(xhr){
if (xhr typeof(xhr) == object xhr.responseText) {
this.sessionId = xhr.responseText;
Fusion.sessionId = this.sessionId;
}
var r = new
Fusion.Lib.MGRequest.MGGetResourceContent(this.applicationDefinition);
r.parameters.session = this.sessionId;
r.parameters.format = 'application/json';
this.oBroker.dispatchRequest(r,
OpenLayers.Function.bind(this.getAppDefCB, this));
}
Basically what happens is that this function is called by this line of code:
window.setTimeout(OpenLayers.Function.bind(this.getAppDef,this),5);. For a
reason that I couldn't identify due to lack of time, the value of xhr is
sometimes equal to 5. Therefore, this causes the code to go into assigning
5.responseText (undefined) to this.sessionId and making it require to login
again.
I'm guessing it has something to do with an underlying library doing some
funky binding/prototyping under Firefox, but I didn't have time to find the
cause. My fix only works because it makes sure the xhr parameter is an
object and has the responseText parameter, so it's not really a clean fix
per say, but atleast it makes things work under Firefox.

Hi all,
I installed MGOS 2.1 Beta yesterday and here are several Fusion problems
that Im seeing:
* Firefox is still prompting for user authentication even when

mentioned in other threads here.
* The Secondary and Main toolbars do not appear in all MapGuide
templates. It looks like they may be covered by other divs. I see this

* Tooltip hyperlinks do not appear as clickable hyperlinks
anymore.
The text of the hyperlink appears though. Both FF and IE.
* Several tooltip problems that I have logged in Trac have not

I will be voting -1 on releasing MGOS 2.1 until the above Fusion problems
are fixed and a newer release of Fusion is included. I realize that most
of
these problems are with Fusion, but as far as I am concerned Fusion and
MGOS
are intertwined in terms of functionality. I will add the new items to
the

and
MrSIDs with 2.1 since others have reported problems with that.
