in reply to Memory needed for perl process

This probably depends on the OS and the version of Perl -- but the question itself is a red herring -- on today's systems (unless you're trying to run Perl on an Arduino), there's plenty of memory to run Perl.

This gave me my morning smile.

More seriously, this administrator has mis-spoken. Installing the modules won't affect the performance of Informatica. Running a script that uses the modules might. Is the Informatica server running flat out, 24/7? no, I didn't think so.

It sounds like you're planning on running something big, if it involves those modules, however. I've been doing ETL development for the last two years, and I run scripts on a virtual machine that sometimes take a minute or two to finish; however, there was one that took 5.5 hours to run. That type of script would have an impact on Informatica, both on the CPU load and on the hard drive sub-system.

I'm guessing this is on a Windows server, an environment that's not as friendly as Linux to multi-tasking. Not knowing your situation at all, is there a way you could run this on your local machine, or alternatively, on a Linux server?

This sounds like a political issue, not a technical issue. :)

Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.

Update: I missed that the platform was HPUX -- my bad. I just read Informatica (which is being used by another team at my site), and ASSUMED Windows.

    Oooh. I could take serious issue with that statement. Suffice it to say, Windows Server is very good at multi-tasking out of the box, and can be truly excellent if used properly.

    This sounds like a political issue, not a technical issue.

    Agreed. Definitely sounds like either: a) someone doesn't want others interfering in his fiefdom; b) or he is scared of introducing anything he doesn't know about into the small pond in which he is the big fish.
