I am running Oracle 8.1.6 and am replicating to one other server. We want to update some column widths in some tables on the master server and I understand this will require doing the same on the server I am replicating to to keep the schema definitions identical. What I am concerned about, is do I need to also update/drop/recreate the snapshots? Also, are there other steps that I need to be aware of before doing this?
