Standby redo logs status on primary

Hi there,

 

I have Setup a dataguard and am checking it with ORACHK (that wonderful tool!). I am confused with an error message about the standby redo logs. I have configured standby redo logs on the Primary.

 

I have 16 redo logs members,

two members per Group. So I have 8 redo log Groups.

This is single instance, so only one thread.

Therefore I need 8 + 1 = 9 standby redo logs.

 

What am I missing here?

 

SQL>
SQL> -- how many redo log Groups do I have?
select count(distinct group#) "Number redo log groups"
from v$logfile
where type = 'ONLINE';

SQL>   2    3
Number redo log groups
