    GCS Shadow process

    Hi,

    What is meant by GCS Shadow process? During RAC instance recovery,the content of alert log is,

    LMS 0: 0 GCS shadows cancelled, 0 closed
    LMS 1: 0 GCS shadows cancelled, 0 closed
    Set master node info
    Submitted all remote-enqueue requests
    Dwn-cvts replayed, VALBLKs dubious
    All grantable enqueues granted

    LMS 0: 1801 GCS shadows traversed, 329 replayed
    LMS 1: 1778 GCS shadows traversed, 302 replayed
    Submitted all GCS remote-cache requests
    Fix write in gcs resources
    Reconfiguration complete
    Can anyone please explain,what these two events are,

    1. LMS 0: 0 GCS shadows cancelled, 0 closed
    2. LMS 0: 1801 GCS shadows traversed, 329 replayed

    Thanks,,,
