Q: What is the role of flex clusters?


A: The hub nodes are directly interlinked within themselves and they are having direct access to storage thus possessing the capability of storing multiple leaf nodes in each hub node.


Q: Why is the security patching so important?


A: Patching is a small section of software that is capable of covering an incomplete security flaw which prevents the data loss risk from creating worse impact than before.


Q: What are different administration tools used by Oracle clusterware?


A: Following administration utilities are used by the Oracle Clusterware :-

  • Server Control Utility (SRVCTL)
  • Oracle Enterprise Manager
  • SQL Plus
