    Unanswered: Oracle RAC

    Hello everybody,

    is it possible to install Oracle 10.2 on Windows 2003 Microsoft Cluster using Microsoft Cluster Services, the task is:

    we have an application, it support Microsoft Cluster Services so we need to install it. But application relays on Oracle 10.2 database and we need to install Oracle in cluster too, what is the best configuration for it? I'm asking cause Oracle have it own clusterware.

    From Metalink note#289836.1:
    Oracle supports Oracle Database Real Application Clusters (RAC) and Microsoft Cluster Service (MSCS) coexistence on the same computer cluster. However, there is no direct integration between RAC and MSCS in Oracle Database 10g.

    When on the same cluster, MSCS and RAC cannot control and manage the same set of disk drives. Administrators must configure the two products so that the shared storage has multiple disk drives, one set for MSCS to manage (which would be comprised of NTFS formatted drives) and one set for RAC to manage (which would be comprised of either OCFS formatted drives, RAW devices or ASM Managed Disks).
    Why?

    "Microsoft Cluster Server is a shared nothing architecture available in Windows 2003 Enterprise / Datacenter Edition."

    Look at Oracle Failsafe. Not RAC. Failsafe is free, it integrates with MSCS and it works pretty well. But it's not RAC.

    I'm not used to Oracle / Windows but wouldn't RAC with ASM (Automated Storage Management) be a solution ? ASM is Oracle's cluster compliant file system introduced in 10gR1.

    Failsafe is free
    RAC is free too with Standard Edition (though very expensive with Enterprise Edition).

    BTW RAC ensures no downtime when a node falls down, while Failsafe does not. Failsafe is NOT a cluster configuration (as you said hmscott, "it's not RAC" ).

    Just a suggestion
