Oracle SOA 12.2.x over Oracle database 12.1 in standby DataGuard with Transaction Guard enabled.
It seems SOA Suite does not support transaction guard, hence you must ask your DBA to configure the service with this setting: COMMIT OUTCOME = FALSE
Caused By: oracle.jdbc.xa.OracleXAException Caused By: java.sql.SQLException: ORA-14911: XA transactions are not supported by Transaction Guard.<oracle.soa.mediator.common> <BEA-000000> <Transaction rollback failed due to exception java.lang.IllegalStateException: Transaction does not exist <Error> <oracle.soa.mediator.dispatch.db> <BEA-000000> <Rollback of transaction failed in DBContainerIdManager.run() oracle.tip.mediator.infra.exception.MediatorException: ORAMED-03504:[Transaction Rollback]Unable to rollback transaction.Possible Fix:Check log file for any ceptions and contact Oracle Support Services for further help.
