ORA-26518: push queue synchronization error detected
Cause: Client tried torepush 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 thattransaction data that RepAPI was attempting to repushed to
the master site exists at the master table and is valid and consistent with thelocal
site. If this error occurs, redundantly identified transactions are ignored andthen
purged from the local updatable materialized view logs. Check that the localsite is
correctly assigning new transactionIDs and is not accidently generating
non-unique values.
