AW: [mapserver-users] Open Layers Problem
your server http://173.236.45.118/cgi-bin/mapserv?map=/home/bicimapas/mapdata/BiciMapasM S.map works also well with OpenLayers. This should show your server with OpenLayers: http://gis.ibbeck.de/olclient/OLClient.asp?WMC=./data/WMC/BiciMapasMS.wmc.xm l Perhaps you use not the right zoomlevel in OpenLayers to see anything. I have to use zoomlevel 16 to see something. by the way also you have corrected it, the mapfile path have to be a filesystem path and not an url.

April 2012 05:17 An: mapserver-users@lists.osgeo.org Betreff: RE: [mapserver-users] Open Layers Problem Brent, Thanks for testing it. The "home/bicimapas/" path is the webserver directory tree. As a fact this same test map works well using the Mapserver templates as you can test with this link http://173.236.45.118/bcmpms_i.html which is the initialization page. Press "Acceder" and you will be taken to the map. The question here is why can the Mapserver template can access the file while OpenLayers does not. Is there a reference document or tutorial on how to properly set up OpenLayers to work with Mapserver?

(http://173.236.45.118/home/bicimapas/mapdata/BiciMapasMS.map) " I suggest that having your mapfile in your home directory tree rather than your webserver's directory tree might be the problem. You might also try tools like uDIG or QGIS to access the WMS service & debug it before you try to get it working with OpenLayers.

Any ideas on how to make it faster. Simplify the data for the that zoom level. If you are all the way zoomed out and drawing all the data, then the shapefile will be fastest. An index does not help if you are drawing all the data as you need to do a full table scan anyway to get all the records. It is simply faster to read 200MB from disk than from the database because the database has to fetch the same data and may have to jump through some hoops to get it out of extended storage, then it has to encode the data and send it over the connection and the client has to decode the data. Do you really need all the resolution of the data at this scale? If not create another column and simplify the geometry into that column and set up your mapfile to query the simplified data at this zoom and to query the detailed data as you zoom in. All of the above is great advice. Additionally, implement a tilecache server; why redraw an image if it has already been drawn. That said, while a db is going to be slower than the file system in many cases, there are many reasons why your db is performing so slowly. Thirty times slow is too much, and 30s for a query, no matter what query, is wrong. Benchmark your entire stack to find bottlenecks... Is the query itself taking that long? Is something else going wrong? Is the exact query that MapServer is performing actually using your indexes? In pgAdmin or from the psql commandline, how long does it take to do: select * from yourtable; Do you have the exact query that mapserver is making? You can get it by adding to the MAP object DEBUG 10 CONFIG MS_ERRORFILE "stderr" then looking in the apache error_log. -Steve ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
