Oracle Oracle Certifications 1Z0-590 Questions & Answers

• Question 81:

  What component of Oracle VM Product is specifically responsible for the automatic failover process?

  A. OCFS2

  B. Server Pool Master

  C. Oracle Clusterware

  D. utility server

  E. virtual machine server

  Correct Answer: B

  http://docs.oracle.com/cd/E11081_01/doc/doc.21/e10898/ha.htm To enable HA, you must first make sure all Virtual Machine Servers in the server pool:

  Use the same shared storage.

  Are in the same OCFS2 or NFS cluster.

  Are Oracle VM Server Release 2.1.2 or above.

  Have the same cluster root, which is a specially designated shared storage used for heatbeating in the cluster. For example, the cluster root might be example.com:/OVS for an NFS cluster, or /dev/sdd6 for an OCFS2 cluster. The heartbeat file would be located at example.com:/OVS/.server_pool_hb for an NFS cluster. There is no heartbeat file for an OCFS2 cluster as one is in-built in the file system.

  Have the cluster root mounted at /OVS. All other storage may be mounted at the standard location of / OVS/uuid.

  Have moved any /OVS mount points (set in FSTAB for Releases 2.1 or 2.1.1) to the /etc/ovs/repositories file. All storage, even that mounted at /OVS, must be maintained in the /etc/ovs/repositories file. You can move the mount points to the /etc/ovs/repositories file with the following command:

  # /usr/lib/ovs/ovs-cluster-check --alter-fstab

  Have a shared cluster root at /OVS, and not local, using clustered OCFS2 on SAN, or ISCSI storage, or NFS on NAS. The default local storage is OCFS2, and is not supported with HA.
