I have did as per request but the still the error throws as below.
Code:
DBD::Oracle::st execute failed: ORA-03106: fatal two-task communication protocol error (DBD ERROR: OCIStmtExecute) [for Statement "select tname from tab where tname='CQC_TEST_CASES'"] at testDB.pl line 19.
DBD::Oracle::st fetchrow_array failed: ERROR no statement executing (perhaps you need to call execute first) [for Statement "select tname from tab where tname='CQC_TEST_CASES'"]

Could you please confirm whether any NLS_LANG or LANG settings need to be changed.

Code:
#!/usr/bin/perl
use strict;
use DBI;
my $ORACLE_HOME = "/oracle/product/10.2.0";
$ENV{ORACLE_HOME} = $ORACLE_HOME;
my $user= "user";
my $passwd= "passwd";
my $sid = "TMT";
my $host = "SS.com";
my $dbh = DBI->connect("dbi:Oracle:host=$host;sid=$sid;port=1588",$user,$passwd) or die "Couldn't able to connect to database $@\n";

my $sql ="select tname from tab where rownum <6";

my $sth = $dbh->prepare($sql);
$sth->execute();
while (my $row = $sth->fetchrow_array)
{
  print $row . "\n";
}
$dbh->disconnect;

dbd::gofer::transport::null

DBD::Gofer::Transport::null(3)				User Contributed Perl Documentation			    DBD::Gofer::Transport::null(3)

NAME

       DBD::Gofer::Transport::null - DBD::Gofer client transport for testing

SYNOPSIS

	 my $original_dsn = "..."
	 DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)

       or, enable by setting the DBI_AUTOPROXY environment variable:

	 export DBI_AUTOPROXY="dbi:Gofer:transport=null"

DESCRIPTION

       Connect via DBD::Gofer but execute the requests within the same process.

       This is a quick and simple way to test applications for compatibility with the (few) restrictions that DBD::Gofer imposes.

       It also provides a simple, portable way for the DBI test suite to be used to test DBD::Gofer on all platforms with no setup.

       Also, by measuring the difference in performance between normal connections and connections via "dbi:Gofer:transport=null" the basic cost
       of using DBD::Gofer can be measured. Furthermore, the additional cost of more advanced transports can be isolated by comparing their
       performance with the null transport.

       The "t/85gofer.t" script in the DBI distribution includes a comparative benchmark.
