jdavidb (email not shown publicly) http://voiceofjohn.blogspot.com/ J. David Blackstone has a Bachelor of Science in Computer Science and Engineering and nine years of experience at a wireless telecommunications company, where he learned Perl and never looked back. J. David has an advantage in that he works really hard, he has a passion for writing good software, and he knows many of the world's best Perl programmers.
As a followup to my previous entry, I just discovered that Oracle's client comes with its own complete installation of perl. It's an older version (5.8.3). This tells me several things:
I don't know what, if anything, Oracle does with this perl (maybe they have programs written against it somewhere in the installation, or maybe they just offer it as an installation of perl which they will personally support and take responsibility for), but whatever it is, they know that they cannot depend on some other party's perl installation, probably for all the reasons I mentioned before.
They're sticking with 5.8.3 right now because that's what's tested with their purposes. If and when they update the version of perl for a future release, it will presumably receive some testing to make sure everything still works with it. It's far more controlled, from their point of view, to upgrade perl when they want to, rather than when the vendor does, or whenever there's a new version.
