Hi François It seems to me that this is more a performance problem of the file server than a QGIS problem. Maybe it is possible to tune something there to improve performance.

I'm also asking myself if the problem is not relative to the fact all the users are opening the same file at the same time. I'm gonna try to make differente file opening the same database... -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] la part de Mike Toews Envoyé : vendredi 28 novembre 2008 01:06 À : Micha Silver Cc : qgis-user@lists.osgeo.org Objet : Re: [Qgis-user] Big sharing problem - Slow when data are shared inmore than one user - QGIS 0.11 Micha Silver wrote: > Could you elaborate on the "extra software and database setup" bit? > Many thanks, > Micha > Hi Micha, To connect PostGIS with ArcGIS products (basic ArcView license and up) you can use zigGIS (http://pub.obtusesoft.com/). This program used to be open source (see http://code.google.com/p/ziggis/ although I've had no luck making it work with 9.2). The developer has since commercialized and revamped the program with a $279 price tag. (In context and ranting in Canadian dollars, ArcView is about $3000, but the minimum license required to connect and edit with an ArcSDE spatial database is ArcEditor, which is about $10000. I think ArcInfo is about $20000, and ArcSDE is about $15000 not including database software, which ranges from $0 for PostgreSQL to $5000 for MS SQL Server and to $60000 for Oracle Spatial). ZigGIS adds some GUI controls to ArcGIS, and it has read/write capabilities. The demo is worth a try, but it only shows a limited number of rows. I don't have a lot of experience with this product, so I can't say too much about any limitations except that it appeared to work fine. To connect PostGIS with Autodesk products (i.e., AutoCAD Map 3D 2008 and up, MapGuide Enterprise or MapGuide Opensource) you can use the PostGIS Provider for FDO (http://trac.osgeo.org/fdo/wiki/FdoPostGISNotes in addition I recommend using the Windows DLLs from http://www.geomapgis.com/web/geomap-group/fdo/index.html). However, this FDO Provider is regarded as beta-quality in every sense (see "Open Tickets" on Trac page). I've run into many issues with this driver, but have overcome many of these with customized trigger functions that synchronize a second replica table for FDO clients. The nice thing about this effort is that the CAD folks where I work can continue to use familiar software to digitize coordinates, polylines, etc., and the geospatial data are identical in QGIS and AutoCAD displays at all times. I've also used PostGIS for a limited amount of time with Manifold System (http://www.manifold.net/), which has built-in support. However, I've had issues with adding and editing shapes since it commits edits instantly without any ability to fill in attributes before, which usually raises PostgreSQL constraint errors (e.g., I need to assign a unique non-null name to each new feature of a certain layer). With all that said, by far my best PostGIS experience with a desktop app is with QGIS, since it works "out of the open source box". I don't need to fabricate any database workarounds for QGIS as I do for FDO, which is of great convenience. The people at my workplace that are using QGIS (starting since 1 month ago) have picked it up quickly, and the value of GIS in the office has gone up quite a bit, since it is no longer exclusive to the few technicians with expensive software. -Mike _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
