Oracle Database Discussions

That sentence doesn't make sense. Have you quoted an Oracle Support note or Documentation verbatim ? Can you provide the URL to the note/document ?

Hmmm.... still unclear.

I've submitted a comment which the documentation team should pick up :
"+This sentence : "Supports Oracle Data Guard such that you can run physical or logical standby databases on it or even we can NOT run primary databases on it either if the primary databases have DG"+
+is not very clear.+
+I can understand it upto the words "on it" but the second part of the sentence, beginning with "or even we can NOT ..." seems mangled and unclear.+
+Can you clarify whether RAC One Node can be used as :+
+a. A Primary in a DataGuard configuration+
+b. A Standby in a DataGuard configuration ?+"

Here's something :

See Oracle Support Article "RAC One -- Changes in 11.2.0.2 [ID 1232802.1]"
which, among other things, says "Dataguard Broker is RAC One aware."

thank you for pointing me to that article.

I'm still confused: do you think it can be used as a primary db ?

In my opinion, using the RAC One Node instance as a Primary should work.
However, technically it is not supported (e.g. because DG Broker can't "recognise" this configuration ?). Therefore, if you do run into errors, Oracle Support would only provide "best effort" and may not be able to provide a solution.

You could log an SR referring to the Support note and ask for details. Also, ask if running a RAC One Node as a Primary in 11.2.0.2 is supported.
