Oracle db Migration from one server to another

Question

Can any body guide me why companies migrate Oracle db from one server to another , & what is the process for doing that?

Answer 1

In that case, something has changed, right? The need to have a standby server has become important.
Next steps:
- define the real business requirements (why do we think we want to spend money on a spare server? why should the money go to a hardware company, instead of an increase in my salary? what benefit are they looking for?)
- see whether any known ideas or alternatives fit the requirements, see whether the backup should be a standby server, a hot failover server, or some other backup mode;
- go to the Oracle Technet site, look under the Product Centers: Database area to see whether there are any related topics (such as 'availability', as one of the logical reasons for a backup is to make the application more avaliable); check in that area for any white papers; read the white papers to formulate an idea, write down interesting keywords;
- look in the Oracle docuentation, list of books, to see whether there are any books specifically dealing with that topic (such as Oracle Data Guard);
- use Google to search for the combination of 'Oracle backup' and the interesting keyword and study several of the sites;
- form a basic plan;
- go to expert and trusted sources (these forums, OraFaq.com), post a plan and ask for feedback.
There are literally dozens of alternatives. Research and find the one(s) that are right for your situation. That includes the technical as well as the financial reasons.
More than anything, that means you need to learn to ask the right question. And that often means asking the same question several different ways, and attempting to answer each variation yourself to see how the answer solves your specific needs.
