RE: I need to change the instance name

Eriovaldo - Often the lot of a DBA is to balance value and risk. Here, you must ask yourself - what is the value of retaining the same instance name, and what are the risks to my production environment? If you perceive the value to be high and the risks low, then go for it. But often (especially after you've been stung a few times) it seems that the value wasn't so great after all. How long can you have your production site down? What happens if something goes wrong and you have them down quite a bit longer than you estimated? You can lower the risk to your production site by creating the new instance (different name), and getting it all prepared before you take the production site down for the export. If most of your users access the instance via SQL*Net (Net8), you can put an alias there, so they don't have to change a thing.

        Of course, if your boss says "do it or else", then the value/risk equation changes dramatically.

Actualy, I am confused, because this is my production environment and I need to get sucess in this operation.

It is necessary, and i would like to keep the old name of instance, because i will change the BD version.
I think the best way is :

1.) backup the software and datafiles
2.) Export all the database
3.) Deinstanll the old software
4.) Install the new version
5.) Create the instance with the old name
6.) Import the database

but it will take a while.
I am looking for a fast way ,

Understand ?

Thanks

Regards

Eriovaldo
