Perl script cannot connect to Oracle from linux shell with error and code

I need some help in determining the problem with my connection from a perl file to a DB.

The code runs and executes fine when it is run from the web (browser to /file.pl url).

In a shell context (putty), when I run the script "perl /file.pl", I get this error:

[date] file.pl: DBI connect('address','username', 'password') failed: 
ERROR OCIEnvNlsCreate (check OR ACLE_HOME and NLS settings etc.) at file.pl line 61

Line 61 reads:

$dbh = DBI->connect(A, B, C );

More details: When another user (with presumably more permissions) runs the file, it works for him (in the shell).

#!/usr/bin/perl -w

require 'include.pl';
require 'bencfg.pl';
use lib '/www/modules/'; #rqd
use DBI;
use DBD::Oracle;

print "Content-type: text/html; charset=UTF-8\n\n";
print "Test Run of connection...\n\n<br>";
print "ORA_HOME: '$ENV{ORACLE_HOME}'\n<br>";  #ORA_HOME: '/opt/o开发者_StackOverflow社区racle/10g/'

#connect to DB
$dbh = DBI->connect(A, B C) || die "Database connection not made: $DBI::errstr";
if($dbh){
   print "OK\n<br>";
   $dbh->disconnect;
}
else{
   print "failed: $DBI::errstr\n";
 }

I know the variables of DBI->connect work. Thats not the issue. I believe its permissions but I cant tell how to fix it.

Some additional info: ORA_HOME: '/opt/oracle/10g'

NLS_SESSION_PARAMETERS

    PARAMETER   VALUE
    NLS_LANGUAGE    AMERICAN
    NLS_TERRITORY   AMERICA
    NLS_CURRENCY    $

Every time I've had this issue with connecting to 10g, I had to make sure NLS_LANG env var was set:

## for utf8 data
$ENV{NLS_LANG} = 'american_america.al32utf8';
## for ios-8859-1 data
$ENV{NLS_LANG} = 'american_america.we8iso8859p1';  

Plus, set ORA_NLS to path of nls files

$ENV{ORA_NLS} = -d "$ENV{ORACLE_HOME}/ocommon/nls/admin/data" ? "$ENV{ORACLE_HOME}/ocommon/nls/admin/data" : 
   -d "$ENV{ORACLE_HOME}/nls/admin/data" ? "$ENV{ORACLE_HOME}/nls/admin/data" : 
   -d "$ENV{ORACLE_HOME}/nls/data" ? "$ENV{ORACLE_HOME}/nls/data"

$ENV{ ORA_NLS32 }     = $ENV{ORACLE_NLS};

Re: More details: ... When another user ... runs the file, it works for him

Try dumping that user's env settings,

env|grep NLS
