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: C,D
According to the Oracle documentation1, two monitoring tools that might be useful in examining I/O performance for the prod database are: cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk (D). This tool can help you monitor the I/O Resource Management (IORM) metrics and identify any bottlenecks or imbalances in the storage layer. I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *p1us . These views can help you monitor the I/O activity and latency at the file, function, and consumer group level.
