Release 10.1B: Progress Fathom Replication
User Guide
Transition
With the introduction of failback to Fathom Replication, both the scope and the functionality of transition increase. While the transition function continues to perform the same operations as always, it now includes the following enhancements to its functionality:
- The role of a target database can be transitioned to that of a normal or a source database. The database can be either online or offline when the transition is performed.
If the target database is transitioned to a source database, AI areas can be added to the target database if they are not present and AI can be started for the database.
If the target database is transitioned to a normal database, the database is available for database update operations, but it can never be transitioned to a source database.
- A source database can be transitioned to a target database. The database can be either online or offline during the transition. If transition is performed on the source and the source is online, a transition failover must be performed. For more information, see the "Completing the failback process" section.
- A source database can be transitioned to a normal database. To do this, you must disable replication by using the following command:
- You can configure transition to restart the transitioned database immediately after the transition process successfully completes.
