monitor cluster interconnect performance
Date: Fri, 8 Aug 2008 11:22:52 -0700 (PDT)
We have a 10g service that is load balanced between 2 RAC nodes. We noticed that query runs about 3x slower if the service is load balanced on both nodes vs running the service on a single node. We did verify that all traffic runs on the private network. On OEM, the GC block access latency was within 12 ms and the GC block transfer rate was within 30ms.
Are these numbers considered high? What other queries or utilities can I use to monitor the performance of the interconnect?
