Hello,

I have a problem to connect direct my program with 9.2.0.5 Oracle DB for Unix 3.50.12.0.
I got to connect them if I install the oracle client but without it it hasn't
been impossible.

The error showed when it tries to connect, it was "not exists TCP:Listener" or something similar.

I need your help because I don't know more things to try.

Thanks in advance,

Alberto

Please specify the connection string you are using to connect to your server.

The connection string is:

"Data Source=cluster;User Id=USUARIO;Sid=orcl;Password=xxx; Direct=true"

Check your connection parameters:

• check letter case
• check your SID (must equal to SERVICE_NAME from tnsnames.ora file)
• set the Port
• cluster must be the name of the PC where Oracle server resides
• this can be the problem with 2 cluster database settings

I could connect it.

The problem was the port, it was different of the default port (1521) and I didn't add it to the string connect.

Thank you very much for all.

You're welcome.
