pawank86 has asked for the wisdom of the Perl Monks concerning the following question:

Hi All, I am trying to connect to ORACLE database using DBI module. The oracle DB is on Linux Env and i am trying to run the script for my system in window Env. I am using following code part to connect:
use DBI; my $dbh = DBI->connect("dbi:Oracle:host=10.27.140.218","user", "passwo +rd");
After executing above code i am getting error : ORA-24327: need explicit attach before authenticating a user (DBD ERROR: OCISessionBegin). Please let me know if i am doing somthing wrong in this. Thanks in Advance..

    From your post I see missing either the SID or SERVICE and port elements on the connect parameters.

    my $dbh = DBI->connect('dbi:Oracle:host=localhost;sid=ORCL;port=1521', + 'scott', 'tiger', { RaiseError => 1, AutoCommit => 0 }); my $dbh = DBI->connect('dbi:Oracle:host=localhost;service=my.service.n +ame.com;port=1521','scott', 'tiger', { RaiseError => 1, AutoCommit => + 0 });

      Hi Generoso, I tried the above code also but getting the same error of need explicit attach. I used SID = 'ORCL', DB port = 1521 and for host i used the IP address of Linux machine where DB is deployed, (machine which i want to connect). Please let me know other possible solutions.

        Have you tried to connect to the database via sqldeveloper form ORACLE it is free; you can downloaded and install it and set up a connection and test if the connecting parameters are the correct ones.

        Have not work with it on UNIX only in windows and is a good tool to debug your sql before you use it on a program or perl script

    Can you connect to this database via sqlplus on Windows?

    Update: Whoops, see DBD::Oracle, providing the sid when connecting.
