To monitor the effectiveness of Persistent Memory (PMEM) cache usage with RDMA on Exadata, information on RDMA I/O statistics can be found in: PMEM Cache User Reads section in the AWR Report: This section provides detailed statistics on PMEM read operations, including user reads that leverage RDMA for direct memory access from PMEM. These metrics help gauge the utilization and efficiency of the PMEM cache . Exadata Metrics (LIST METRICCURRENT): By using the LIST METRICCURRENT command within the Exadata environment, real-time metrics related to PMEM usage and RDMA I/O statistics can be accessed. This provides an immediate view of the current performance and activity on Exadata’s persistent memory components . These tools together offer insights into PMEM cache usage and the effectiveness of RDMA for optimized data access.
