I/O performance of the prod database on your Exadata Database Machine has degraded slightly over the past month. The database has been allocated to the OLTP I/O Resource Management (IORM) category.
Which two monitoring tools might be useful in examining I/O performance for the prod database?
Correct Answer: A,D
1. OS I/O metrics using Enterprise Manager host pages for the storage servers: Enterprise Manager provides a detailed view of the storage server's performance including I/O metrics and statistics. You can use these metrics to analyze I/O performance and identify any bottlenecks.
2. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk: These commands are used to gather information about storage server performance, including I/O statistics, disk usage, and resource allocation.
