   1. Hi Abdul,

      The procedure is same as 11g r2 rac. Only difference is you can now create leaf nodes in addition to the hub nodes (conventional nodes) as well.

            1. Sorry mam for delay,the error no was

               INS-06006- passwordless ssh connectivity not set up between the following nodes or they were not reachable.

               The os version is OEL6 update6 64bit and db,grid is 12.1.0.2

            2. It appears that second node is not accessible from first one. Check pinging from OS prompt.
               If required chk /etc/hosts or DNS settings

            3. i have not configured DNS server as i was not able to find proper doc for configuring dns server for scan ip just given entry in side the /etc/host file the public,private,vip,scan ip
               the public and private ips are pinging.

               Thanks.

            4. Hi Abdul,

               Try to configure ssh connectivity manually and see if you get any error message.

2. Hi Mam,
   i have agained tried on oel6 update5, both the nodes are pinging but user equivilence test is not passed manually i have tried.
   i have noticed this error may occur due to preinstallation rpms.
   can u send link for 12c database,rac preinstalltion rpm download links.

   Thanks.

      1. Thanks for the link, but previously also i had gone through this docs if i choose

         Oracle Linux 6 Preinstallation RPM Without ULN Support
         http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/x86_64

         click the above link for downloading any rpm it is giving file not found output.

         Thanks

            I think you have customized Linux installation and have not installed rpm for openssh which is required to establish ssh connectivity. Just check and install it.
