問題3
Consider the following setup:
User A1 belongs to resource group High on Database A.
User B2 belongs to resource group Low on Database B.
User C3 is a user on Database C without any DBRM setup.
DBRM setup:
Database A: Resource group High gets 80% and Low gets 20%.
Database B: Resource group High gets 60% and Low gets 40%.
IORM setup:
Database A: Share=20, limit=5
Database B: Share=30, limit=10
Database C: 5 shares
Total number of shares in the IORM setup = 100
What percent of I/O will each database user theoretically be using when the Exadata storage unit I/O throughout is used 100% and no other databases but A, B, and C are running?
