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 });` [download]	[reply] [d/l]

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.	[reply]

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	[reply]

Can you connect to this database via sqlplus on Windows? Update: Whoops, see DBD::Oracle, providing the sid when connecting.	[reply]
