Oracle Message ORA-00155 - cannot perform work outside of global transaction

ERRORcannot perform work outside of global transaction
CAUSEThe 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.
ACTIONCheck 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.
