    Cache Fusion -  write/write contention

    967967
      Hi,

      I have a question regarding Oracle RAC Cache Fusion - Write/Write Contention.

      I would like to know the concept in Write/Write Contention. For example in 3 node cluster A,B,C when node A is updating a block in its cache and after few mins the node B requests for the same block that is already cached in node A. As per the Cahe fusion technology in this case the node A creates the PI image and sends the block to node B. But here i would like to know what happens if node A has not commited the changes it made.

      Thanks,
