Enhancements to transition functionality
With the introduction of failback to OpenEdge Replication, both the scope and functionality of transition have increased in the following areas:
Support for additional transition scenarios
Transition encompasses the following activities:
- 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.
- A source database can be transitioned to a normal database, provided you first disable replication.
- You can configure transition to restart the transitioned database automatically after the transition process successfully completes.
Intuitive transition processing
The transition process is intuitive; it chooses the appropriate type of transition to perform based on the following criteria:
Automated transition functions
All transition operations can now perform automated processing. Some of the automated processing is controlled by new transition properties in the replication property files. Other automated processing is based on the state of the database that is being transitioned.
The transition operation includes these (and other) automated functions:
