Reverse resync provides the following three operations:

ReverseResyncBegin (alias: RRBegin, RRStart, ReverseResyncStart): You can use RRBegin operation to mount the snapshot volumes and the Oracle instance.

It lets you preview the Oracle instance from the snapshot volumes.

ReverseResync Begin operation supports three types of recovery methods: manual, auto, and auto_until_scn.
ReverseResyncAbort (alias: RRAbort, RRCancel, ReverseResyncCancel): You can use this operation to end reverse resync preview session and get back to the original data volumes.

ReverseResyncCommit (alias: RRCommit, RRFinish, ReverseResyncFinish): You can use this operation to commit the reverse resync changes that are previewed in RRBegin operation.

Note:

After this operation finishes, you cannot go back to original data volumes. The snapshot volumes are permanently restored on to the data volumes. Storage checkpoints or the filesnaps that are created after the snapshots, which are used for reverse resync, are not available after the completion of RRCommit operation.
