Cluster Management 6-29 Monitoring Cluster Performance Tools Overview Several tools exist to monitor performance of your cluster. Use the tools to regularly monitor the performance of each node and each Oracle instance. The gathered information might identify a disparity in the workload being performed by each node, which signifies a need to adjust the distribution of the workload so that the overall cluster performance is maximized. I Compaq Insight Manager can be used to gather low-level, in-depth hardware statistics for the server and networking hardware components used in the cluster. I Secure Path Manager is used to manage redundant I/O paths to MA8000/EMA8000 Storage Subsystems. Secure Path Manager displays a graphical representation of the current multiple path environment and indicates the location and state of all configured storage units on each of the paths. I StorageWorks Command Console (SWCC) gathers hardware statistics for the storage subsystem components. I Windows 2000 Performance Monitor gathers performance characteristics of many objects. Examples of monitored objects are memory, processor, hard drive performance, network software, and application software. I Oracle8i Performance Manager captures, computes, and presents performance data about the Oracle database. Specific data about Oracle8i Parallel Server metrics are monitored and viewed with this application.
