Yes, what I was looking for, so to speak.   To tell you the truth I believe the 
client believes they are OK, and they are not going to get a lawyer because 
they are licensed via an embedded license from the Vendor...
:)  All one can do is what one can do.  Ultimately it is up to the client and 
vendor to reveal any caveats - and apparently there are some.  I certainly 
cannot obtain a lawyer, nor a sales agent.   One would think the SR would be 
routed to such a department, but its not; and it's a severity 4 SR; leading me 
to start a conversation about it.

Hi Joel,

Therefore, there is no command possible for the standby that would violate the 
data guard licensing provisions.    This is the question.   It appears you 
answered it below eventually.

I agree with you completely. Look at what happens when I try enabling Data 
Guard on my test 11gR2 Standard Edition DB:

SQL> startup
ORA-00439: feature not enabled: Managed Standby

I think you're safe as long as DBA_FEATURE_USAGE_STATISTICS shows 0 in 
DETECTED_USAGES for the given feature you're concerned with.

From the same SE instance:

SQL> select detected_usages, total_samples, currently_used, first_usage_date, 
last_usage_date
  2  from DBA_FEATURE_USAGE_STATISTICS
  3  where name = 'Data Guard';

DETECTED_USAGES TOTAL_SAMPLES CURRE FIRST_USA LAST_USAG
--------------- ------------- ----- --------- ---------
              0             3 FALSE

Hope this helps.

-Justin

I am not asking how to do it.

Since it's often confused by various people, just to reiterate: All servers 
must be licensed, whether in r/w, r/o or recovery disconnect.

And, as clarification, standby is not DataGuard.  DataGuard is simply a 
technology that automates the process [work] flow of standby for Oracle
databases: the extraction, shipping, receiving, application of logs and 
coordinated switchover/failover control.

Basically Oracle is saying you can not configure DG, although nothing - as far 
as I can tell - is stopping you from manually doing the same thing as Data 
Guard provides.

Rather than try to duplicate DG capabilities, just peek at DbVisit, an Oracle 
partner who provides a great & legal standby solution for Standard Edition at a 
very reasonable price. http://dbvisit.com
