A node in a four-node cluster encounters corruption on the OLR and must be restored from backups taken using clusterware utilities.
Identify the option that shows the correct OLR restore commands.

  1. crsct1 stop crs
    ocrconfig -local -restore /my_olr_backup_location
    ocrcheck -local
    crsct1 start crs
    cluvfy comp olr
  2. ocrdump -local -backupfile /my_olr_backup
    ocrcheck -local
  3. crsct1 stop crs
    ocrdump -restore -backupfile +DG_FRA/myolr_backup
    ocrcheck -local
    crsct1 start crs
  4. crsct1 stop crs
    ocrconfig -local -manualbackup
    ocrconfig -local -restore /my_olr_backup_location
    cluvfy comp olr
    crsct1 start crs
  5. crsct1 stop crs
    ocrcheck -local -restore /my_olr_backup_location
    cluvfy comp olr
    crsct1 start crs

Answer(s): A

Explanation:

Run the following command to list the backup files:
ocrconfig -showbackup
The ocrconfig -showbackup command displays the backup location, timestamp, and the originating node name of the backup files that Oracle Clusterware creates. By default, the - showbackup option displays information for both automatic and manual backups but you caninclude the auto or manual flag to display only the automatic backup information or only the manual backup information, respectively.
Run the following command to inspect the contents and verify the integrity of the backup file:
ocrdump -backupfilebackup_file_name
You can use any backup software to copy the automatically generated backup files at least once daily to a different device from where the primary OCR resides.



You want to change an existing Oracle Clusterware standard Cluster to an Oracle Flex Cluster. There Is Grid Naming Service (GNS) and Flex ASM configured right now. In what order do you need to take the following steps?
- Stop Oracle Clusterware.
- Determine the current mode of the cluster.
- Ensure that the GNS is configured with a fixed VIP.
- Change the mode of the cluster to be an Oracle Flex Cluster.
- Use the Oracle Automatic Storage Management Configuration Assistant (ASMCA) to enable Oracle Flex ASM in the duster.
- Start Oracle Clusterware.

Which statement accurately describes the benefit of the policy-managed database feature with Oracle KAL 12cR1?

  1. It protects against cascade failures due to network usage. It migrates workload isolation to specific pools. Less important workloads shut down immediately.
  2. It protects against cascade failures due to load. It ensures that workload isolation is balanced between pools. Less important workloads start transactionally.
  3. It protects against cascade failures due to load. It ensures workload isolation between pools.
    Less important workloads shut down transactionally.
  4. It protects against cascade failures due to load. It ensures workload isolation between pools.
    Less important workloads shut down and start uniformly.
  5. It protects against cascade failures due to load. It ensures workloads are not isolated between pools. Less important workloads shut down transactionally.

Answer(s): C

Which tasks and in which order must be performed, before you can change the mode of a standard cluster to Flex?

  1. 1. The node role must be set for each node in the cluster.
    2. You must ensure that the GNS is configured with a fixed VIP.
    3. Flex ASM must be enabled for the cluster.
    4. Clusterware must be started on each node.
  2. 1. Clusterware must be stopped on each node.
    2. You must set the Flex ASM cardinality.
    3. Flex ASM must be enabled for the cluster.
    4. Clusterware must be started on each node.
  3. 1. You must ensure that the GNS is configured with a fixed VIP.
    2- Flex ASM must be enabled for the cluster.
    3. Clusterware must be stopped on each node.
    4. Clusterware must be started on each node.
  4. 1. Clusterware must be stopped on each node.
    2. New Application VIPs must be created.
    3. You must ensure that the GNS is configured with a fixed VIP.
    4. Clusterware must be started on each node.
