Hi Monks,

I am trying to replicate the sqlplus '/as sysdba' connection using DBI and DBD::Oracle by following the guidelines from http://search.cpan.org/~pythian/DBD-Oracle-1.23/Oracle.pm#Connect_Attributes.

My tnsnames.ora is like this: 

#Generated tnsnames.ora by gen_tnsnames.sh script
#Localnode service connectivity 
ABCD12.COMPANYDOMAIN.COM = 
  (DESCRIPTION = 
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = TCP)(HOST = testserver24.companydomain.co
+m )(PORT = 30710)) 
    )
    (CONNECT_DATA = 
      (INSTANCE_NAME = ABCD12) 
      (SERVICE_NAME = ABCD12.COMPANYDOMAIN.COM) 
    )
  )

[download]
and I have no problem connecting with the usual sqlplus '/as sysdba'.

I am doing the following in my script: 

use DBI;
use DBD::Oracle qw(:ora_session_modes);

my $dsn = "dbi:Oracle:";
#$ENV{ORACLE_SID} = "ABCD12";
$ENV{ORACLE_SID} = "ABCD12.COMPANYDOMAIN.COM";
delete $ENV{TWO_TASK};
my $dbh = DBI->connect($dsn, "", "", { ora_session_mode => ORA_SYSDBA 
+});

[download]
and getting the error: 
DBI connect('','',...) failed: ORA-12545: Connect failed because targe
+t host or object does not exist (DBD ERROR: OCIServerAttach)

[download]

Specifying ORACLE_SID with/without the domain name doesn't change the error message. I have checked that $TNS_ADMIN is defined and the host name is present in /etc/hosts.

What am I doing wrong here?

Thanks, Ani
