Hello,

In a 2-node cluster is it possible to have 2 Rac Clusters,
installed on the 2 servers ? If so, any issues to consider.

thanks

    Do you mean two different two-instance databases? Yes, its possible.
    Nothing really special to worry about it.

    Right, to follow up with what Andrew said, and to (hopefully) clarify, if you have a two-node cluster, there can and will be only one instance and version of clusterware installed. This is true regardless of how many clustered databases will be running on the cluster.

    I suppose nothing "special" except that you'll have very few options
    for allocating resources between the two database instances on each
    node in the cluster. This is why I personally strive for a single RAC
    instance on each node of the clusters I deal with. In most cases,
    people are using RAC for their most sensitive, mission-critical
    application, so it's usually relatively easy to make the argument for
    finding somewhere else to put the "other" databases. This usually
    provokes a discussion about whether the database(s) in question
    *really* are mission-critical or not. Or, alternatively, consolidate
    them into a single database where some resource allocation can be made.

    This problem is really not much different than putting multiple
    single-instance databases on a standalone, non-clustered server.
