Does disable CPU hyper threading will have direct impact or maybe unexpected behavior to Oracle RAC database?
Actually the background of this question is we have many received packet queuing on the network layer waiting to be processed. Investigation leads to the processor utilization which shows that many processor are still in idle state or not used when the other processors are busy processing incoming request.
I have visited some oracle note like
CPU Count Consideration for Oracle Parameter Setting When Using Hyper-Threading Technology (Doc ID 289870.1)
