hi experts ,

I have question and that is in horizontal clustering in obiee 12c  if we have 2 nodes

Node 1 with complete installation and configuration and on node 2 we have only weblogic and obiee install .

Now if incase the Node1 completely crashes then how can I bring the Admin Server up on Node 2

What is the mechanism for it

Thanks

    Hi,

    I'm not an expert at OBIEE high availability setup, but I think you will need to provide more information about your high availability architecture in order to provide an answer to your question. But if you haven't already taken a look, I could point you towards the Oracle document that provides information about failover.

    The Doc you gave in the link i know that

    my question is in horizontal clustering do we need virtual ip

    if not then what will happen if server 1 crashes can i bring the admin server on server 2 up and running

    If you want true HA then yes you will need a Virtual IP for the Admin Server listen address.

    But more importantly you'll need to install the software on a share that both nodes can see.  That way, even if the whole Node 1 server goes down you can still use the Admin server and Node 2.

    So the basic idea is:

    1  Install Weblogic and OBIEE on a share

    2  Move Machine 1 to local disk on the first server

    3  Clone the machine and move it to local disk on the second server

    Does that help?

    hi pete ,

    Thank you for your answer

    But instead of virtual ip if we use load balancer and take the virtual ip out of the picture then still the admin server on node 2 can be brought up right ?

    Thanks

    Just want to add that scaling and high availability are two different things and as Pete mentioned,  there are a bunch of steps needed to perform to achieve HA. Simply scaling the OBIEE instances horizontally with a load balancer does not achieve HA.

    ok so with HA the virtual ip is must then
