Just to answer my older question which is already archived and cannot be replied: access with perl to remote oracle server without local installation of oracle client
I wrote a perl tk application which needs access to a remote oracle server. The oracle instant client should not be installed on each customers pc running the tk programm.
So the perl programm itself was converted with the par-module to an exe and from the oracle instant client Oracle Instant Client Downloads
only the oraociicus11.dll had to be copied/installed into the same directory where the exe was located.
