We would like to implement Advance availability in our environment.
but we does not want to configure Mirror server ( fail over server/ back up server ) in the configuration. is it possible ?
and where do I get detailed information about advance availability.
I'm not sure why you would want to implement Advanced Availability without a Standby Server but yes you can.
Details can be found in the Implementation Guide.
Below document has more information about the AA setup:
SDM 12.9 Advanced Availability
Thanks for your time however we could able to open the document which is posted in this thread.
Sorry, in AA you must have a standby server.
Otherwise you can’t do maintenance (applyptfs etc).
Some task on the background server can only be done when you switch from BG to STBY and vice versa.

Thank you for the information , one more question is if BG server is down then automatically Mirror server will get up or we manually need to do some thing ?
Our team presented a webinar just on this topic last year. It includes high level overview of AA, how to perform maintenance and how to handle planned and unplanned outages.
Maybe that webinar would help us address some of these items and much more?
It will not come up by itself, you will need to configure some mechanism to do this.
The failover can be invoked through an HTTP request if you have configured the HealthServlet so combining this with sufficiently advanced monitoring system you can have the failover automated. Just don't forget to secure the servlet to avoid unintentional failovers by robots or nosy people crawling your network
That’s a great point Jussi. Securing HealthServlet is critical.
Here are a few other items that I came up with about AA:

Thanks for your entire team efforts for the video, its really good video to get started with AA.
I have attached a PDF version of the document Naveen_Desham was referring to
