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.
