Confusion between types of quarantine in Exadata

edited Jul 19, 2024 10:47PM in Exadata General (MOSC) 2 commentsAnswered

Which two quarantine types can disable Smart Scan for multiple databases that offload SQL
statements to a cell on an Exadata Database Machine?
A. SQL Plan Quarantine
B. Manually created Quarantine
C. Database Quarantine
D. Disk Region Quarantine
E. Cell Offload Quarantine

well this question gets asked in exadata certification exam 1Z0 902 .

Cell offload Quarantine looks definitely one of the correct answers as it will affect multiple databases using storage from the same cell being quarantined.

Sql plan looks unlikely as different databases may not have same PHVs due to different data sets and structures.

Can Disk region quarantine be an option ?
