LD_LIBRARY_PATH (at least) really does need to be set before the process
starts. You can do this by writing a shell wrapper, or re-execing your
perl script if the value is not already set.
You're using linux and I'm not sure if this sort of messing about is
required there.

Have you considered doing a require instead of a use. With require, the
loading is done at run time, and would be governed by the setting of
LD_LIBRARY_PATH, at the time the require statement is executed. Just set
LD_LIBRARY_PATH before doing the require.

RE: How to set LD_LIBRARY_PATH
I'd argue you want to use a shell wrapper anyhow, because rather than setting
those variables explicitly, you ought to do something like:
export ORACLE_SID=your_sid
export ORAENV_ASK=NO
. oraenv
and Oracle will set it all for you, and if/when something changes or is
upgraded, your code will continue to do the right thing.

Some DBI question -
Hi, Am trying out DBI for Oracle and just want to know if for example, I need to include column formatting stuff etc., is it best to just put them into a .sql file and then execute the .sql file instead of placing them in the Perl DBI script? Also, is there anyway to sort of "hide" the password somehow when using Perl DBI? Any advise or feedback will be very much appreciated. Thanks in advance.
