Invoking perl cartridge from another perl cartridge

Question

Hi,
I have a perl cgi tht I am porting to the cartridge framework and am having the following issue:
the perl script "opens" another perl script (and "system"s another). THis does not seem to work in my setup presumable because the standalone version of perl is not installed. Now, I want to get the performance benefits of a cartridge while invoking these other perl scripts. Also, I know that I can make these other scripts as modules and it will work, but how do I invoke these scripts via a cartridge (they are in a different folder).
An example (with any requisite syntax) will be greatly appreciated.
regards

Hello,
Whilst it's possibly to 'call out' to an external Perl module, I think you're actually probably making things more complicated by going that route.
As an alternative, why not have the Perl code actually connect to the Oracle database and check for the data changing itself?
If you do want to perform the external call yourself, then the following AskTom thread should give you some ideas on how to do it -

There's actually some other options, you could actually connect to the other databases directly from the Oracle DB (using dblinks, hetrogenous connectivity etc), or you could convert the Perl module (or wrap it) so that it's callable via a URL in which case you could then perform an HTTP call from out of the database using utl_http.
It really depends on the specifics of what your perl module does, what sort of processing etc.
