V$FLASHBACK_TXN_GRAPH

V$FLASHBACK_TXN_GRAPH displays a tabular representation of the transaction dependency graph. For each dependency edge, there could be multiple rows, one for each conflicting operation..

This view is relevant AFTER a compensating transaction has been started through the DBMS_FLASHBACK.TRANSACTION_BACKOUT() set of functions, and is no longer relevant once the compensating transaction is either committed or rolled back. It also provides a tabular representation of the undo SQL that is not available through the CLOB XML construct in the DBA_FLASHBACK_TXN_REPORT view.
