That you get this message on your primary database suprises me a little. 
In my experience the primary is somewhat a 'normal' database with an extra 
remote archive_log destination.

Do I understand correctly that these database reside on the same host? My first 
guess (always my worst), is that somehow the redolog files are mixed up/ used 
by both databases.

Problems I would expect on the secondary node.

Maybe you can supply some values from the init-file from both primary and 
secondary node, so we maybe can see some misconfiguration. Ow...and the tns 
names?

Probaly the more interesting parameters to have a look at are:
db_name
DB_UNIQUE_NAME
dg_broker_config_file1 <== But I guess you do not have DG_Broker configured 
allready
dg_broker_config_file2 <== But I guess you do not have DG_Broker configured 
allready
dg_broker_start=TRUE   <== But I guess you do not have DG_Broker configured 
allready
fal_server
log_archive_config
LOG_ARCHIVE_DEST_1
LOG_ARCHIVE_DEST_2
LOG_ARCHIVE_DEST_STATE_1
log_archive_dest_state_2

Anyway...as Andrew Kerber also said, I have spend numerous hours cursing DG, 
just to find a misspelling or relalizing that I misunderstood the scenario :-(


Best Regards,
Martijn
