HOST not working on UNIX 9iAS

Question

I am attempting to HOST a command out to the middle tier. When I try this in 9iDS, it works like expected (copy c:\temp\a.txt c:\temp\b.txt). However, when I push the form up to the unix box and attempt to run the same command on the server through the webforms (cp /home/foo/temp/a.txt /home/foo/temp/b.txt), it does not work.
Everything that I have read says that the HOST command runs the command on the middle tier (which is what I want), but something is not right. I have checked the UNIX permissions, tried running the command through a shell file [host('/home/foo/test_copy.sh')], calling it from a shell [host('sh /home/foo/test_copy.sh')] and anything else I can think off. A just will not copy to B. Any ideas on what might be wrong?

Answer 1

HOST are executed with permissions who had start Forms listener.
Check UNIX permissions. Named user can read sourse file and write into target directory. If target file exist then user can write it too.
