ORA-12840: cannot access a remote table after parallel insert direct load txn
这个是什么错误,怎么解决?

------解决方法--------------------------------------------------------
Cause: Within a transaction, an attempt was made to perform distributed access after a PDML or insert direct statement had been issued.

Action: Commit/roll back the PDML transaction first, and then perform the distributed access, or perform the distributed access before the first PDML statement in the transaction.
