Oracle : Ошибка ORA-26518

"push queue synchronization error detected"
*Cause: Client tried to repush a transaction has already been committed at
the master site. A common cause of this problem is an error at the
local site in initializing or updating the local site transaction
sequence mechanism.
*Action: Verify that transaction data that RepAPI was attempting to
repushed to the master site exists at the master table and is
valid and consistent with the local site. If this error occurs,
redundantly identified transactions are ignored and then purged
from the local updatable materialized view logs. Check that the
local site is correctly assigning new transactionIDs and is not
accidently generating non-unique values.
