A: The Oracle Management Service (OMS) provides the services used to coordinate the storage of management information and the automation of management activities for all entities managed in the network. It also includes facilities for serving the web-based user interface, which is the Cloud Control console.

B: The Management Agent is the lightweight process that acts as a proxy for Enterprise Manager on the various hosts in the network where entities that Enterprise Manager manages are located. It communicates with the OMS to collect and deliver monitoring information and to coordinate management activities executed against the management entities.

E: The Management Repository is the Oracle Database that stores all important management information for the entities managed by Enterprise Manager. The Oracle Management Service (OMS) uses the Management Repository to store and retrieve key information, such as monitoring data.

Correct Answer: C

Database Lifecycle Management Pack comes with out-of-box Deployment Procedures to provision and patch the Oracle Database (both Single Instance Database and RAC) including the underlying infrastructure. Enterprise Manager supports segregation of duties, so that a Designer can create the provisioning and patching workflows while an Operator can simply deploy the databases using those workflows.

Correct Answer: A

The Connector Framework is installed to the OMS home. The $ORACLE_HOME in the procedure below refers to the OMS home.

1.

Download the Connector Framework installable files from OTN by clicking Downloads, then Enterprise Manager.

2.

Stop OMS by running: $ORACLE_HOME/opmn/bin/opmnctl stopall

3.

Start the Oracle Universal Installer (OUI) by running the following command:

For Linux or Unix:

$ORACLE_HOME/oui/bin/runInstaller

For Windows: $ORACLE_HOME\oui\bin\setup

4.

When prompted by OUI, locate products.xml in the installation source directory: connectors/framework/10.2.0.2/1.0/source/Disk1/stage

Correct Answer: BCE

C: An Administration Group is a special type of group designed to automatically deploy management settings (monitoring templates, compliance standards, cloud policies) to targets when they join the group. Administration Groups are created by defining their membership criteria based on target properties.

Note:

* The group home page continues to provide an overview of the status and health of members of the group and a central way to launch operations on the groups, such as submit jobs, start blackouts, and so forth.

Correct Answer: ABC

A:

*

Oracle Enterprise Manager Ops Center uses firmware profiles to provision, or update firmware on an asset.

*

Oracle Enterprise Manager Ops Center supports a wide variety of hardware resources. This release of Oracle Enterprise Manager Ops Center has been extended to support the firmware update of components such as RAID Controllers,

Expanders, Disks and PDUs. You can now manage the firmware for a variety of hardware resources in Oracle Enterprise Manager Ops Center.

B: Oracle Enterprise Manager Ops Center supports Ethernet and InfiniBand network protocols.

C: In Oracle Enterprise Manager Ops Center, networks become part of a network domain in the following ways:

An asset that has a network is discovered.

A user creates a network.

A network is created when it is required. This is a dynamic network.

Correct Answer: ABC

Correct Answer: B

*

The Oracle VM Manager provides the user interface that allows you to create and manage zones, virtual server pools, virtual servers, and guest virtual machines. Before you use the Oracle VM Manager to manage virtualization targets in Enterprise Manager, you must register an existing installation of the Oracle VM Manager.

*

A virtual server is a generic term used to describe a physical box which has virtualization software (hypervisor) running on it. A new virtual server can be provisioned by installing the OVM Hypervisor on a bare metal box. Before you add a virtual server to a server pool, it must be discovered.

*

Setting Up Networks

. You can define a name or an alias for each logical network. When you have created your networks, you connect the physical network ports on Oracle VM Servers to the logical networks. Before you define the logical networks in Enterprise Manager, you have to review your physical network configuration that you intend to use, such as VLAN and subnet usage. Setting up an Oracle VM network involves: Generating MAC Addresses Creating and configuring VLAN Groups Creating Networks Reference: Setting Up Cloud for IaaS

Correct Answer: C

Live Migration

To take advantage of Enterprise Manager Ops Center's live migration capability, the server pool must be configured with the following:

*

Oracle VM for SPARC 2.1 or higher (2.2 is recommended)

*

The SPARC T4 server has a minimum firmware level of 8.1.1 (8.2.0f or higher is recommended)

*

All networks and storage libraries are physically presented to all servers in the server pool as well as being defined in Enterprise Manager Ops Center

*

All CDOMs have network connectivity to all other CDOMs in the server pool.

*

The agent on the CDOMs is must be online.

Correct Answer: E

Using this mechanism [out-of-place patching] means that the only downtime will take place when the Databases from the previous Home are switched to run from the new Home. If there is any issue with the Database patch, you can switch back to the previous unpatched Home since it is still available. So, patch rollback is a lot faster. Note: A new mechanism for patching has been provided in Oracle Enterprise Manager Cloud Control 12c, known as Out of Place Patching. This is now the recommended method and creates a new Oracle Home, which is then patched while the previous Home is still operational. All this is done using an out-of-box Deployment Procedure in Enterprise Manager.
