Name
ROLLBACK_SEGMENTS
Synopsis
Value: comma-separated list of rollback segment names (except SYSTEM)
Default: NULL
Specifies one or more rollback segments to allocate by name to this instance. If this parameter is set, an instance acquires all of the rollback segments named in this parameter, even if the number of rollback segments exceeds the minimum number required by the instance (calculated from the ratio TRANSACTIONS / TRANSACTIONS_PER_ROLLBACK_SEGMENT). You can also specify public rollback segments if they are not already in use. If this parameter is not set, the instance uses all public rollback segments by default. Multiple instances must have their own rollback segments.
