Hi, We are planning to copy an oracle database to one host(sndhpu10) to another host(sndhpu14) in the same cluster. The database is of 3TB, what is the best procedure to acquire it with less downtime?
Is it of a sap basis guy work or an oracle admins work?? if sap basis guys then?
What can a sap basis can do to aquire it to reduce the downtime 
.
An oracle guy tried in his manner and said it took for him 8 hours for 1.5TB of data.
What is the best process of reducing the downtime? further it goes to prod? 
regarding the boxes.
sndhpu10 is presently our database box we are running our sap test system eccxdb (database) on it and sndhou14 is our new box which don't have any thing running on it it is entirely free we want to set up elxdb (database) on it. The sndhpu10 and sndhpu14 hpunix boxes are on the same cluster.
Please check the diagram I attached for easy over look?
Thanks
