I've gathered some more info using Systernal's Filemon utility. It seems that phpcli.exe does ask Windows about my TNSNAMES.ORA file; Windows replies that the file exists. But PHP does not even try to read it. It only reads the following file:


	names.directory_path = (TNSNAMES)
	# names.default_domain = world
	# name.default_zone = world

The only files it searches and is not found is:


There isn't a sdns.ora file anywhere on disk.

When I run the same script through mod_php then Apache.exe opens *and reads* TNSNAMES.ORA :-? Received on Thu Apr 10 2008 - 05:17:54 CDT
