Purpose

 Why a rollback segment has the status of "needs recovery", what the status means, and how to resolve it.

Rollback segments can be monitored through the data dictionary view,dba_rollback_segs. There is a status column that describes what state the
rollback segment is currently in. Normal states are either online or offline.Occasionally, the status of "needs recovery" will appear.

When a rollback segment is in this state, bringing the rollback segment offline or online either through the alter rollback segment command or
removing it from the rollback_segments parameter in the init.ora usually has no effect.
