[Mapserver-users] Help with ArcSDE Layer Connection/Data spec ification

Reading other posts on troubleshooting MapServer, I came across the
suggestion to run mapserv from the command line with the same parameters as
from the html page. When I do so, I get interesting results as shown below.
./mapserv?map=/usr/local/apache2/htdocs/demoSNL/demo.map&layer=nercsubrgnsta
tus&zoomsize=2&program=/cgi-bin/mapserv&map_web_imagepath=/usr/local/apache2
/htdocs/tmp/&map_web_imageurl=/tmp/
[11] 9803
[12] 9804
[13] 9805
[14] 9806
bash: ./mapserv?map=/usr/local/apache2/htdocs/demoSNL/demo.map: No such file
or directory
[15] 9807
[10] Done
map_web_imagepath=/usr/local/apache2/htdocs/tmp/
[11] Exit 127
./mapserv?map=/usr/local/apache2/htdocs/demoSNL/demo.map
[12] Done layer=nercsubrgnstatus
[13] Done zoomsize=2
[14] Done program=/cgi-bin/mapserv
The interesting thing about these results is that even though it says "No
such file or directory" with regard to the demo.map file, it is obviously
reading the demo.map file since that is where the connection information is
that is generating the missing layer error when the layer is not specified
properly (and it read it before I tried modifying it to use ArcSDE). So, I
figure the problem must be with some file specification within the demo.map
file but I can not find anything that appears to be wrong.
I'm still baffled but perhaps this will help those of you who are trying to
help me. In the mean-time, I will try starting over again from the existing
demo application. My approach is to take the working demo application and
modify it to read a layer from ArcSDE instead of the default shape files. I
started out by changing only what I thought needed to be changed. However,
in the process of trying to debug the problem, I began commenting out more
and more things from the map file.
If this does not work I will go through the process of trying to build the
entire application from scratch. It will be a good learning experience
anyway.
Any suggestions are appreciated.
Thanks again,
Clay Pryor

specification
Setting up the "esri_sde" alias in the /etc/services file is very nice and
works fine.
At one time I believed that my problem was with the name. However, with the
combinations for specifying the name that I have been using and considering
Paul's comment about the name, I have come to believe that something else
must be going on.
Let me explain. First, before posting my original message, I tried the
following DATA definitions:
1) DATA "nercSubRegions, shape" #layer name with no schema
2) DATA "SDE.nercSubregions,shape" #layer name with schema
3) DATA "insistdb.SDE.nercSubregions,shape"
4) DATA "insistdb.SDE.NorthAmerica.SDE.nercSubregions,shape"
Options 1 and 2 resulted in the following error:
Internal Server Error: (from apache web server log) "Premature end
of script headers: mapserv, referer: http://.../demoSNL/demo_init.html"
Options 3 and 4 resulted in the following error:
Web page result: "MapServer Message msDrawMap():Image handling
error. Failed to draw layer named 'nercsubrgnstatus'. msSDELayerOpen():
SDE error. SE_layer_get_infor(): Layer not found. (-20)"
Based on the errors alone (undefined internal mapserv error vs. Layer not
found error) I was originally thinking that options 3 and 4 were an
improvement over options 1 and 2.
However, with Paul's comments about the naming I began to realize that
options 1) and 2) were probably correct with regard to the name while
options 3 and 4 were off base. Therefore, I tried the following
intentionally misnamed layers to see what resulted.
5) DATA "SDE.xx,shape" # garbage 1
6) DATA "xx,shape" # garbage 2
Both returned the Layer not found error.
This is disconcerting to me because it indicates that the correct naming is
returning an unreported error from mapserv. To try to eliminate any other
script conflicts, I have tried to simplify my application as much as
possible by eliminating all but the basics.
I am including all of the relevant source code in this email in hopes that
someone can make sense of the problem. Please let me know if there are
other files that I should attach.
Perhaps this is some sort of configuration problem????
Once again, thanks in advance for any help.

Two possible things, firstly, are you sure that 'port:5151' is what you
want for your instance? You could try a bare '5151'. Or you could edit
/etc/services and add esri_sde there as a tcp service on port 5151, then
use 'esri_sde' as the instance. SDE is wierd.
Secondly, it looks like your table name is right, but you can never be
too sure. Tables I have used have almost always been inside schemas, and
were referenced as SCHEMANAME.TABLENAME.
