From perl program query is not executed.
I have tried executing one particular query through perl.But I am unable to get the result. When I tried to execute the sysdate query its working when I executed my perl code.

The below query doesn't work.
QUERY 1:
Code:
my $sql ="select name from tab where rownum <6";

Received ora error :ORA-12705: Cannot access NLS data files or invalid environment specified

QUERY 2:
The below query works out.
Code:
my $sql ="select sysdate from dual";

When I tried to manually execute the 1st query without perl I am getting the output.
Code:
 
SQL> select tname from tab;
TNAME

The error indicates that the Perl script is executed in a different environment (most probably via cron). Make sure all necessary Oracle related variables are set before invoking the Perl script: ORACLE_HOME, PATH etc.
Code:
ORACLE_HOME=<your_oracle_home>
PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_HOME PATH
<run you script>

do I need to invoke all the above oracle variables to invoke inside the perl script.

Just put them on top of your script. See orafaq "Setting the Oracle environment" for more.

I have included the below variable in my perl code.

Please confirm
Code:
#!/usr/bin/perl
use strict;
use DBI;
ORACLE_HOME = "/oracle/product/10.2.0";
PATH="$ORACLE_HOME/bin";
export ORACLE_HOME PATH;

No, you need:
Code:
my $ORACLE_HOME = "/oracle/product/10.2.0";
#You may also need to set the ORACLE SID
#my $ORACLE_SID="your_sid";

$ENV{ORACLE_HOME}=$ORACLE_HOME;
# Uncomment if you set ORACLE SID above
#$ENV{ORACLE_SID}=$ORACLE_SID;
$ENV{PATH}="$ORACLE_HOME/bin";

Code:
$ENV{ORACLE_HOME} = "/oracle/product/10.2.0";
$ENV{PATH}="$ORACLE_HOME/bin";
export ORACLE_HOME PATH;

I am getting the below eror when executing.
Code:
Global symbol "$ORACLE_HOME" requires explicit package name at test.pl line 5.
Bareword "PATH" not allowed while "strict subs" in use at test.pl line 6.
Execution of test.pl aborted due to compilation errors.
