Question 2

- IORM shares out available I/O resources using shares.
- To implement a custom IORM plan, a service request is required.

- IORM is configured by using the database resource manager.
Correct answer: AB
Question 3
Which two statements are true about configuring IORM? (Choose two.)
- IORM will only intervene when I/O resources become limited.
- Each database is allocated a share value between 1 and 64.
- If an Exadata Service has three databases, one with a share value of 2, another with a share value of 4, and the third with a share value of 1, the first database will get two I/Os out of every seven, the second database four I/Os out of every seven, and the last database one I/O out of every seven.
- If an Exadata Service has three databases, one with a share value of 4, another with a share value of 2, and the third with a share value of 7, and only the first database is doing I/O, it will only receive four I/Os out of every 13.
- Custom IORM plans can be created using the ALTER IORMPLAN command from SQL *Plus when connected to one of the instances.
