What is my SID? host?

Posted on 2004-09-18

I've just installed an Oracle database (10g) on Windows XP. I think the installation was successful, because I can log into a database using "SQL Plus". Now I'm trying to use Oracle's Migration tools connect to the destination (i.e. this newly installed Oracle database). It requests I submit my username, password, host, port, and sid, and when I do, it issues a generic error message (i.e. Incorrect Host, Port, or Sid...). I'm pretty sure my username and password are correct, since I just created them and granted all privleges to this user. The port also seems to be correct, because it is the default port (1521), and netstat shows that some server is indeed listening on this port.

Should host be either  "localhost" or ""? Should "sid" just be the name of the target database (already created), as spelled in my tnsnames.ora file? If so in both cases, how can I go about solving this problem?

Thank you.

can you post your tnsnames.ora file?

but usually should be in the format of "localhost:1521:<SID>"  but SID should be the database name, NOT the entry name in tnsnames.

go to start->run
typ:                   cmd

in the command prompt type

you'll get your ipaddress.

Part II
go to control panel->Administrative tools->services

your sid is identified here as OracleService<SID>
