Narender, Transportable Tablespaces might allow you to load data in an offline instance then quickly "plug in" the new data to the production instance.

We are thinking of provide 24* 7 services to customers with out going offline. What are the best possible solutions ? I had few but I donot know its right direction ................. Possible Solutions Replication - * not possible until Oracle 9i spatial (because of the restriction on replicating objects). * Even then expense of additional licensing/machinery may be too great Duplicate instances - have 2 instances and users switch from one to other after production load.-- how to implement ? Duplicate schema within current database. Have 3 schemas inside a single TIPSPROD instance. The schema with the current data remains in production until the second schema is loaded with the new data. This is can only work if we introduce a third schema that holds the views. At certain time, we redefine all the views in the DATAVIEWS schema. --- its kind of duplication --- certainly not my option Can some body direct me where to look or any ideas ?
