This is just a harmelss debug message (that shouldn't be printed IMHO in the 
Open() method of the DB2 driver. cc'ing David)

No the issue is that the \ windows directory separator was used instead of / 
for http ressources.
Just fixed with https://trac.osgeo.org/gdal/ticket/6310

You might get some extra open speedup by defining 
GDAL_DISABLE_READDIR_ON_OPEN=EMPTY as env. var/config. option (this prevents 
probing for (most) side-car files. This is not something to use in general 
however.
