Problem in connecting Perl with Oracle

Hello

I've installed Perl 5.10 successfully and all other perl program running
perfectly.
But it's showing following problem when i'm trying to connect oracle
Problem:
1. The procedure entry point OCIXML TypeCreateFromSrc could not be located
in the dynamic link library OCI.dll.
2. install_driver(Oracle) failed: Can't load
'C:/Perl/lib/auto/DBD/Oracle/Oracle.dll' for module DBD::Oracle: load_file:
The specified procedure could not be found at C:/Perl/lib/DynaLoader.pm line
202
at (eval 4) line 3
Compilation failed in require at (level 4) line 3.
Perhaps a required shared library or dll isn't installed where expected at
dbi.pl line 3
See below mentioned coding from which I intended to connect Oracle (dbi.pl)
use strict;
use DBI;
my $dbh = DBI->connect( 'dbi:Oracle:orcl','scott','tiger',)|| die "Database
connection not made: $DBI::errstr";
$dbh->disconnect();
Thanks
