Oracle : Ошибка ORA-31427

"publication %s already subscribed"
*Cause: The subscription already contained this publication.
*Action: Check the values of subscription_name and publication_id.
Check any other subscribe calls to see if they subscribe
to columns that are shared among more than one publication
on the same source table. Do not attempt to subscribe to
the same publication more than once in the same subscription.
Use the publication_id variant of the SUBSCRIBE call if
needed to specify precise publications.
