Re: I need to change the instance name (to Dennis)

Dennis :

Thanks for your answer.
Well, I need to downgrade my database, changing EE for SE, so ... The most problem is that the v$instance is used in the aplication. I saw in the metalink a document that helps to change the db_name and not the instance_name, understand..
so ...
I thought to create the new one, with the new name and migrate to it and after it to change the name to the old one... Like that, i shouldn't change the application .

But i hope that the best way is :

Deinstall and install the new version.
And to migrate it fully.

Right ?

Regards
Eriovaldo
