Subject: providing 24*7 database ---
hi gurus,
Our shop ( GIS oracle spatials ) attempting to provide a production database
(7x 24 hours) , currently we have to offline database for users while
loading of data.
we donot what users to access data while loading.
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 ?
TIA
