In order two support a new application, you are planning to add a RAC VM cluster to an existing Oracle Exadata X9M-2 deployment.
Which two methods can be considered?

A. Use the xm command.
B. Use domu_maker utility.
C. Use Oracle VM Manager.
D. Use the OEDA web-based configuration tool.
E. Use the OEDA Command line interface.

答案：D,E

解題說明：
For adding a new RAC (Real Application Clusters) VM cluster to an existing Oracle Exadata X9M-2 deployment, you can utilize the Oracle Exadata Deployment Assistant (OEDA). OEDA is available in two interfaces:
OEDA Web-based Configuration Tool: This web-based interface facilitates the configuration of Exadata environments, supporting both physical and virtual deployments. The graphical interface helps in defining VM clusters, including RAC clusters, and ensures the configuration aligns with Oracle best practices.
OEDA Command Line Interface (CLI): For more advanced or automated tasks, the command-line interface (oedacli) allows for precise control over the deployment process. It supports various configuration actions such as adding or removing clusters, resizing ASM disk groups, and managing VM clusters.
These tools are specifically designed for Exadata configurations and provide a streamlined approach for deploying and managing RAC clusters in both physical and virtualized environments.

問題 #86

C. Failed storage server updates are automatically rolled back to a previous release.
D. Updating kernel and RDMA packages on storage cells should be prevented by excluding them with the yum -exclude option.
E. For regular Exadata updates, yum automatically installs a non-UEK kernel, which can be selected to boot from grub.
F. Failed database server updates are rolled back to a working state on a previous release automatically.
