Suggested Answer: BDE 🗳️
D: The cssdagent and cssdmonitor provide the following services to guarantee data integrity:
✑ Monitors the CSS daemon; if the CSS daemon stops, then it shuts down the node
✑ Monitors the node scheduling to verify that the node is not hung, and shuts down the node on recovery from a hang.
Note If the Oracle Clusterware itself is working perfectly but one of the RAC instances is hanging , the database LMON process will request a member kill escalation and ask the CSS process to remove the hanging database instance from the cluster.
On a Linux/Unix system CSS consists of ocssd.bin, cssdmonitor, and cssdagent.
E: Cluster kill daemon (oclskd) handles instance/node evictions requests that have been escalated to the Cluster Synchronization Service (CSS).
Incorrect Answers:
C: Ocssd manages cluster node membership and runs as the oracle user; failure of this process results in a node restart.
