    WINDOWS OS rollover patching in RAC .

    User536214 - Oracle

      Hello Team,

      I have few question as below .

      Oracle have any best practices for OS patching?

      Is OS  patching supported in a rolling fashion?

      For Example : i have 4 nodes RAC database running on windows servers.if nodes 1& 2  has been patched while 3&4 Nodes has old patching  levels of drivers or patches  until the patching is completed .

      1)Will the instances in the cluster be ok to run with different levels/version of patching ?

      2)What if something fails, how long could we run with different versions/levels of patching?

      3)would it be best to do a complete shutdown of the cluster and patch all nodes at the same time, once OS patches applied, then bring back the cluster?
