Oracle Error Description
ORA-00155: cannot perform work outside of global transaction
Reason for the Error ORA-00155: cannot perform work outside of global transaction
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.
How to fix the Error ORA-00155: cannot perform work outside of global transaction ?
You can fix this error in Oracle by following the below steps
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.
