Greetings,
I am new to Data Guard and have a question concerning configuration. I
am running Oracle EE 10.2.0.3.0 on RHEL4 and setting up a physical
standby. I haven't been able to find a specific answer to this question
in the documentation and hoping someone can help. In the primary I the
following is set...
SQL> show parameter name
NAME TYPE VALUE
------------------------------------ -----------
------------------------------
db_file_name_convert string /opt/oracle/edrs/,
/opt/oracle
/edrs/
db_name string edrs
db_unique_name string edrs
global_names boolean FALSE
instance_name string edrs
lock_name_space string
log_file_name_convert string /opt/oracle/edrs/,
/opt/oracle
/edrs/
service_names string edrs
I understand that on the standby server the db_unique_name must be
unique but it is not clear to me whether the db_name,instance_name and
service_names must also be unique. From some of the examples I have
found it appears that the db_name and instance_name may be the same but
I am not sure. I also don't find anything indicating that the
service_names parameter must also be different on each node. It doesn't
seem like it needs to be but I'm not sure. Any help appreciated.
Thanks.
