Ok, As of now broker doesn't have any inconsistency properties.
Its main issue is, you changed value of LogArchiveTrace from SQL Plus when your configuration managed with Broker, I suggest you not to use Sql Plus when you are using Broker.
So as of now this property value unable to get from Broker configuration.
Now reset the value of LogarchiveTrace from SQLplus as Mseberg mentioned, then will see
SQL> alter system set log_archive_trace=0;
and then further manage only with broker.
