Under normal operation, when going from multi-site to single-site, shut down the Receiver Servers and Update Process as well as any passive Source Servers and any inactive application servers. Then perform the MUPIP RUNDOWN operation of the database.

For an extended shut down, switch the active Source Server on the originating instance to passive to prevent it from trying to connect with a replicating instance. Under normal scenarios, the originating instance operates alone, so that when a replicating instance comes back, replication resumes where it left off.
