Planning for transition
To use transition effectively, you must plan for it in advance by setting all the transition properties. If you do not set the transition properties, full transition processing does not occur. Instead, the extent of transition is limited to changing the role of a database from target to normal.
Plan for transition by making all of the following decisions:
- Which is the primary and which is the secondary database?
To begin transition planning, decide which database is your primary database and which is your secondary database. The primary database is the one on which users initially perform updates.
- What type of transition will occur?
Consider whether the target database will be transitioned to a source database or normal database.
- What type of after-imaging functionality should be implemented?
You can choose to start AI automatically on the transitioned database. You can also add AI areas.
- Do you want the database to restart automatically after transition?
Think about whether you want to control database startup or have the transition process start the database.
- Will transition automatically attempt to recover in the event of a failure?
A backup must exist in order for automatic recovery to occur.
Once you make each of these decisions, you can set the transition properties accordingly, as described in the "Setting transition properties" section.
