oracle error - ORA-00155: cannot perform work outside of global transaction

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.

ORA-00154:	protocol error in transaction monitor
Cause:	The transaction monitor returned TMJOIN on an AX_REG call but the transaction was locally suspended.
Action:	Contact the transaction monitor customer support.
