Re: Is it possible to reorganize tables for logical standby while maintain the synchronization?

I agree with Ric that it should be possible. However, there is a possibility that apply process will go crazy as object_id and data_object_id will be changed in LSTBY database (as mentioned - test, test, test). In this case an alternative is to reinstantiate the table but it will need to pull all the data from primary via db link and might actually impact your primary db (at least you will need to make sure you don't hit ORA-1555).
