5.8.3, not 5.3 :-) I'm guessing it already comes with DBI and DBD::Oracle.

Now you're running into a few other issues that take a bit more to resolve. Again, I'll reiterate: install a private perl. And then we can more or less resolve the rest of the issues.

Let's say you install perl 5.16.0. Depending on how your environment is set by the job scheduler, different solutions may present themselves. If, for example, it simply puts Oracle's perl first in the PATH, you can just put your first line to be: 

#!/opt/myperl/5.16.0/bin/perl

[download]
and everything is fine after that. However, if your code is actually being run directly by a hardcoded-in-the-scheduler perl, that is it's running /u01/oracle/product/10.2.0/perl/bin/perl $yourscript directly, it's a bit more convoluted. My suggestion would be to write a wrapper (in perl 5.8.3 syntax). Roughly something like this: 
#! perl

# delete $ENV{...} to clean up the environment if needed

exec {$0} "$0-wrapped", @ARGV;

[download]
And then have a -wrapped version of the file with your real code in it that starts with the appropriate line above in it. This will have the job scheduler launching the Oracle perl which then reads this file, and it will then tell the kernel (AIX) to execute another program in its place. The kernel will read the magic number from the new program ("#!") and interpret it as a script that needs interpretation, read the rest of the line for the interpreter, and then run that. So it's a bit of an annoyance, but it should all run quick enough not to be noticed.

And, as a bonus, you'll be able to use the new features in newer perls. Like 5.8.8. :-P
