Examine this IORM plan: Which two are true concerning this plan?
A.
The Finance database can use at least 45%, but never more than 60%, of the total Flash Cache capacity.
B.
I/Os from the finance database are guaranteed to get a minimum of 45% of the I/O bandwidth if the demand exists, and a maximum of 60% of the I/O bandwidth even if no other databases are doing I/O to the cell, and the demand from the finance database exceeds 60% of the maximum I/O rate of the cell.
C.
If I/Os come from the HR database only, then they may get up to 100% of the I/O bandwidth on the cell.
D.
I/Os from the finance database are guaranteed to get 45% of the I/O bandwidth if the demand is at least 60% of the maximum I/O rate of the cell, but may get 100% of the I/O bandwidth if no other databases are performing I/O to the cell.
E.
If I/Os come from the HR database only, then they may get up to 10% of the I/O bandwidth on the cell.
Suggested Answer:BE🗳️
The IORM plan can be configured using the ALTER IORMPLAN command on command-line interface (CellCLI) utility on each Exadata storage cell. It consists of two parameters - dbplan and catplan. While the "dbplan" is used to create the I/O resource directives for the databases, the "catplan" is used to allocate resources by workload category consolidated on the target system. allocation/share - Specify the resource allocation to a specific database in terms of percentage or shares. limit - Specify maximum limit of disk utilization for a database. Incorrect Answers: A: IORM plans configures % I/O resources, not % of Flash Cache. References: https://community.oracle.com/docs/DOC-998939
Why is the answer given as E and not C?
Here we have no limit for HR database as it falls under name=OTHER and it can have 100% I/O if only I/o's are from this database
