Oracle Database 12c: RAC Administration — Question 20

Which three statements are true concerning node evictions and reboots performed by Oracle Clusterware 12c?

Answer options

• A. All node evictions require that the evicted node or nodes be rebooted.
• B. A node whose performance is severely degraded can be evicted.
• C. The OCSSD process may evict a node after an escalation request from a database instance LMON process.
• D. The CSSDMONITOR process can request a node eviction.
• E. The OCLSKD process is used for node eviction requests originating on the node to be evicted.
• F. The reboot advisory broadcasts reboot decisions only over the interconnect.

Correct answer: B, D, E

Explanation

Statement B is correct because nodes with poor performance can indeed be evicted to maintain cluster health. Statement D is accurate as the CSSDMONITOR process can initiate evictions, while E is true since the OCLSKD process handles eviction requests from the node being evicted. Options A and C are incorrect because not all evictions require a reboot, and the OCSSD process does not rely on LMON for eviction requests.
