The asamMigrationStatus object represent the ASAM's status for what concerns its migration capabilities. Whereas two of the six values, viz. 'forceRollBack' and 'removeRollBackDatabase' may be specified in a management protocol set operation, three values wil be returned in response to a management protocol retrieval operation: 'idle', 'migrating' and 'rollBackPossible'. That is, when queried, this object can represent only three migration related states of the ASAM: the ASAM has no specific migration state, i.e. it is simply operational (the object has value 'idle'); the ASAM is busy migrating (the object has value 'migrating'); or, the ASAM has recently migrated but is still able to rol back to the previous configuration (the object has value 'rollBackPossible'. Whenever a management station wishes the ASAM to roll back to its previous configuration it has to set this object to value 'forceRollBack'. Setting the object to value 'removeRollBackDatabase' informs the ASAM it has not support the rollback feature anymore. As a result the ASAM will perform clean up operations (e.g. free the roll back database). Remark: this object is subject to improvement in future releases (e.g. coupling of data and software upgrade/rollback).
