- Orphaned entries reported in v$streams_transaction.

- V$streams_transaction will show all open transactions being captured, which means transactions where capture has not yet found a 'commit' or 'rollback' at the redo / archived logs, not actually active transactions as seen on v$session / v$process. Therefore even a database bounce will not clean some of these transactions.

- Besides the open transactions as defined above, we might also see orphaned entries on these objects, which means that the transaction was actually applied fine, but there were not cleaned up properly.

- So there will not be corresponding entry of txn from v$streams_transaction in v$transaction.
