Expand description

Top-level analysis result for an undo tablespace.

Fields§

§rseg_slots: Vec<u32>

§rseg_headers: Vec<RsegInfo>

Per-rollback-segment details.

§segments: Vec<UndoSegmentInfo>

Per-undo-segment details (from RSEG slot traversal or direct scan).

§total_transactions: usize

Total undo log headers found.

§active_transactions: usize

Count of segments in ACTIVE state.
