Given this test program that connects to Oracle:

#!/usr/bin/perl -I/home/install/perl
$ENV{'ORACLE_HOME'}="/home/root/home/xyzco/oracle/oracle/product/12.1.
+0/dbHome_1";
$ENV{'LD_LIBRARY_PATH'}="/home/root/home/xyzco/oracle/oracle/product/1
+2.1.0/dbHome_1/lib:/lib:/usr/lib";
use DBI;
print $ENV{'LD_LIBRARY_PATH'};

$dbh = DBI->connect( "dbi:Oracle:host=127.0.0.1;sid=V1011679;port=1521
+", isx, devpassXD0kei4Eo3W3n9n, { AutoCommit => 1} );

The output is as follows; i.e. it fails to connect complaining that it can't load /home/install/perl/auto/DBD/Oracle/Oracle.so. 

site1:/home/install/perl/auto/DBD/Oracle # perl test.pl

HOWEVER, if I explicitly define the environment variable in the shell: 

site1:/home/install/perl/auto/DBD/Oracle # declare -x LD_LIBRARY_PATH=
+"/home/root/home/xyzco/oracle/oracle/product/12.1.0/dbHome_1/lib:/lib
+:/usr/lib"

and then run the program: 

site1:/home/install/perl/auto/DBD/Oracle # perl test.pl
AJS Dynaloader -/home/install/perl/auto/DBI/DBI.so-
AJS Dynaloader /home/root/home/xyzco/oracle/oracle/product/12.1.0/dbHo

+usr/libAJS Dynaloader /home/root/home/xyzco/oracle/oracle/product/12.
+1.0/dbHome_1/lib:/lib:/usr/lib

...then it is successful. Why doesn't the program work when I define the environment variable from inside the program but not in the shell? OS is SLES11. Thanks for your help!
