Tuning Inter-Instance Performance in RAC and OPS (Doc ID 181489.1)
This note was written to help DBAs and Support Analysts understand Inter-Instance Performance and Tuning in RAC.
Real Application Clusters (RAC) uses the interconnect to transfer blocks and messages between instances. If inter-instance performance is bad, almost all database operations can be delayed. This note describes methods of identifying and resolving inter-instance performance issues.
See Oracle Support Doc ID 181489.1 for details.
