Transition
The reorganization transition marks the point from which instances of versioned classes are no longer available to applications until the reorganization completes (or fails and is aborted). The transition can proceed only when no versioned schemas and classes are in use.
Updates to objects in user data files (versioned or unversioned) are not allowed after a transition has begun. Only the reorganization process is allowed to update files during the offline phase.
A reorganization can be configured to attempt to initiate the transition as soon as the object conversion phase is complete. Alternatively, the reorganization is suspended and the transition must by initiated by an explicit user action at a later stage.
If the transition cannot proceed because schemas and classes are in use, the reorganization log file lists the processes that are using these. In addition, you can use the Classes In Use Browser in the JADE development environment to identify the classes being used by each process.
