ORA-16439: Standby not ready to receive redo at this time Cause: A logical standby ordown stream capture database was not in a state
where it could accept a request to receive redo from another database. This was
likely due to the database not being open. Action: See the databasealert log at the receiving side of the transfer for details of
why the database was not ready. If the database was mounted but not open, open
it to clear the problem. The initialization parameter LOG_ARCHIVE_DEST_
STATE_n at the sending site may need to be set to ENABLE.
