    Hi Kumar,

    Please gothru the Installation guides under http://service.sap/com/instguides for required SAP DVD's and PAM for compatible DB's.

    In Node A --> You start with ASCS + SCS installation as below

    1.) Central Services Instance for ABAP (ASCS) -- Consists of Msg. service & Enqueue Service (Shared Disk)

    2.) Central Services Instance (SCS) -- Consists of Msg. service & Enqueue Service (Should be installed after installation of 1.) (Same Shared Disk)

    3.) First Microsoft Cluster Service (MSCS) -- This step creates the SAP cluster group on the first MSCS node and adds the ASCS and SCS instance(s) to the SAP cluster group

    4.) Database Instance

    Node B

    5.) Additional Microsoft Cluster Service (MSCS)

    6.) Enqueue Replication Server BOTH NODES, First in NODE A followed by NODE B

    7.) Central Instance NODE A-- If you install the central instance on one of the NODE A, make sure that you use a local drive, not a shared drive.

    8.) Dialog Instance NODE B-- Same procedure as in NODE A.

    When NODE A fails, the ASCS and SCS failsover to NODE B and Dialog instance on NODE B act as CI.

    Refer to below doc for more information - http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00004f25-6190-2b10-2c8b-fa419234c28b
