    Please help to explain latch:ges resource hash list and enqueue hash chains?

    user13565975

      Could you please help to answer the following Questions:

      1. What’s the “latch: enqueue hash chains” ? When will happen ?
      2. What’s  the “latch: ges resource hash list”?When will happen?
      3. Is there any relationship about the two latches(latch: enqueue hash chains and latch: enqueue hash chains)?
      4. Is there any relationship about the two latches(latch: enqueue hash chains and latch: enqueue hash chains) with enq TX contention ?
      5. Will “latch: enqueue hash chains” cause high “latch: enqueue hash chains” ? If Yes, why ?
      6. Can we confirm that there are many concurrent operations when we found there are greater than 100 Buffer Busy Waits and en Tx contention?
      7. Any advice about the above sheet?

      Thanks

      BestRegards
