I have Oracle Database 11g Enterprise Edition Release 220.127.116.11.0 - 64bit Production (Windows platform).
Now I have to communicate to remote database via ODBC. I know we need to use Heterogeneous Services. I am a Java Developer not DBA. I need simple step by step process to do this.
I know about the link
But I even want simple steps.
Like, open listener.ora file do some stuff, open tnsnames.ora do some stuff....like this.
