getAbortJournalNumber(): Integer;
The getAbortJournalNumber method of the JadeDatabaseAdmin class returns the number of the journal containing the Begin Transaction record of the oldest active transaction. When this method is called on a secondary database, it returns the oldest journal required for an undo operation in the event of a hostile takeover or the next required replay journal if no journals have been replayed in the current session.
If there are no active transactions, the number of the oldest journal required for recovery is returned.
