I need to have two copies of my data within one instance. One
copy is updateable by an admin user and the other copy is read-
only by other users. The problem is that I want to allow the
admin user to update the data without the others being affected
until the admin user decides that the new data is to be made
available i.e. normal users work with the old data until the
admin user is finished entering the new data.
My initial idea is to use read-only snapshot replication to
provide the normal users with snapshots of the admin user's
data. Then, when the admin user finishes entering new data a
refresh can be done and all the other users can then see the new
data.
Is this a sensible way to do things? Should I be using a second
instance? This would no doubt increase the licensing costs? I am
relatively new to Oracle so am not sure if there is a better way
to achieve what I need.
Thanks for any advice,
Grant Fitzgerald
