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

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.
