ORA-12840: cannot access a remote table after parallel/insert direct load txn

What triggered the Error:

Within a transaction, an attempt was made to perform distributed access after a PDML or insert direct statement had been issued.

What should we do to fix it:

Commit/rollback the PDML transaction first, and then perform the distributed access, or perform the distributed access before the first PDML statement in the transaction.
