Oracle : Ошибка ORA-00155

"cannot perform work outside of global transaction"
*Cause: The application tried to perform some work on either an Oracle
7.3 server or an Oracle8 server with local transactions disabled
while outside of a global transaction.
*Action: Check if the application is connected to an Oracle 7.3 server. The
Transaction monitor must not return a NULL XID on an AX_REG call
when the resource manager is Oracle 7.3. If the application is
connected to an Oracle8 server, either set nolocal=f in the
xa_open string or start a global transaction prior to attempting
the work.
