Find Detail of Transaction in Oracle

When working with DML statements, you can confirm the details of a transaction by querying from the V$TRANSACTION view.

For example, inserted data into a table; before you issue a COMMIT or ROLLBACK, you can view active transaction information for the currently connected session as follows:

SQL> insert into emp values(1, ‘John’, ‘Smith’);
SQL> select xidusn, xidsqn from v$transaction;
XIDUSN XIDSQN
———- ———-
9 369
SQL> commit;
SQL> select xidusn, xidsqn from v$transaction;
no rows selected
