An ORA-24784 'Transaction exists' error occurs when using Oracle XA.
An attempt was made to start a transaction, while attached to a non-migrateable transaction
Issuing a query containing a database link starts a distributed transaction that is non-migratable, even if it is only a query. An XA transaction cannot then be started without a commit or rollback being issued first.
