Hi,

is it possible to sync both ways in active data guard?

i'm asking this question to see if it can be a solution for my problem which is:

i need to convert my oracle database with no downtime,by converting i mean applying DDLs and DMLs to the database while keeping my users working.

so i was thinking of configuring data guard and at the time of conversion i'll take a snapshot of the standby database and apply my conversion,after that i'll end up with 2 databases different from each other ,

so my question: is it possible to sync this snapshot database with my primary without loosing the data already modified in my primary?

Howdy, Stranger!
