Oracle Exam 1Z0-070 Topic 4 Question 18 Discussion

Actual exam question for Oracle's 1Z0-070 exam
Question #: 18
Topic #: 4
[All 1Z0-070 Questions]

You issued these commands to all Exadata Storage Servers in an X6 Exadata Database Machine using dcli:

alter iormplan objective = low_latency

alter iormplan active

There are no database or category plans defined.

You are encountering disk I/O performance problems at certain times, which vary by day and week.

DSS and Batch workloads perform well some of the time.

Further investigation shows that at times, the workloads are all OLTP I/Os, at other times all batch I/Os, and sometimes a bit of each.

You wish to have disk I/O managed so that performance will be optimized for all workloads.

Which statements would you issue to all Exadata Storage Servers to achieve this?

Show Suggested Answer Hide Answer
Suggested Answer: D

The supported IORM objectives are auto, low_latency, balanced, and high_throughput. The recommended objective option is auto which allows IORM to continuously monitor the workloads, and select the best mode based on the active workloads currently on the cells.
