Release 10.1B: Progress Fathom Replication
User Guide


Completing the failback process

It is your responsibility to ensure that there is no activity occurring on either the primary or the secondary machine when you initiate completion of failback. Also, be sure to have all users logged off as well.

To complete the failback process, execute the following command on the secondary machine for the secondary database:

dsrutil db-name -C transition failover 

In which:

db-name is the name of the database on the secondary machine.

transition failover causes the replication server on the secondary machine to tell the replication agent on the primary machine to start transition. If the transition failover command completes normally, the secondary database is transitioned into a target database.

As part of the transition, both databases shut down automatically and restart in the appropriate configuration, if you set the restart-after-transition property accordingly. The database on the primary machine is again a source, and the database on the secondary machine is again a target. For details about the restart-after-transition property, see the "Transition properties" section.

Figure 4–3 illustrates the failback process from secondary replication through the end of failback.
