Response in error situations

If the DBTT could not be extended then a message specifying the reason for this is output.

If the failure of the DBTT extension was due to the failure of the necessary realm extension then further extension attempts for this DBTT are ignored until the realm extension suspension has been terminated.

If a failed online realm extension results in a suspension due to a high extension granularity then you may still be able to perform a successful online DBTT extension using the DAL commands REACT INCR and EXTEND DBTT.
