Discover the Exadata Cloud Target Using Console

Starting with Enterprise Manager 13.5 Release Update 12, the discovery of Oracle Exadata Database Service on Cloud@Customer target is integrated with the discovery of Oracle Autonomous VM Clusters and Oracle Storage Servers.

Starting with Enterprise Manager 13.5 Release Update 14, the discovery of Oracle Exadata Database Service on Dedicated Infrastructure target is available in Enterprise Manager Cloud Control.

Starting with Enterprise Manager 13.5 Release Update 18, the discovery of Oracle Exadata Database Service on Dedicated Infrastructure target is integrated with the discovery of Oracle Autonomous VM Clusters.

The Exadata VM cluster targets of the type X8M and X9M are multi-VM clusters.

Before you begin, ensure that you completed the prerequisite tasks.

Here are the steps to discover the Exadata Cloud target:

  1. Open the discovery wizard:

    1. From the Enterprise Manager home page, select the Setup menu (upper right corner), Add Target, and then Add Targets Manually.

    2. In the Add Targets Manually page, click Add Using Guided Process.

    3. In the Add Using Guided Process dialog box, under the Guided Discovery column, select Exadata Infrastructure and click Add.

    The Exadata Infrastructure Discovery page opens.

  2. Provide details of the monitoring agents:

    1. Under Monitoring Agent, select the agent that has access to OCI REST API endpoints. See Agent Installation.

    2. Optionally, you can also specify an agent as Backup Agent. If the agent designated as Monitoring Agent is down, the Backup Agent will be auto-assigned to monitor the target.

  3. Provide Oracle Cloud Infrastructure (OCI) details:

    When you sign up for Oracle Cloud Infrastructure, Oracle creates a tenancy in one region. This is the home region. It contains the account information and the identity resources. The subscribed regions are those regions to which you might have subscribed later for accessing resources in a different geographical location.

    Note that the guided discovery process performs discovery of Exadata Cloud resources in a single subscribed region at a time.

    1. Select the Home Region in which your tenancy is provisioned. If your region is not listed in the menu, then select Other.

      When you select Other as your home region, then you can specify the region identifier in the adjacent text box. Select from the Region Identifier column corresponding to your region listed at Oracle Cloud Infrastructure Documentation: Regions and Availability Domains.

    2. Under Oracle Cloud Infrastructure Named Credentials, from the menu, select the named credentials associated with your OCI account that you had identified as part of the prerequisite tasks.

    3. Select the Subscribed Region where you want to perform the discovery. The options available in this menu are updated based on your selection of home region, OCI named credentials, and monitoring agent.

    Click Next.

  4. Select the Exadata Cloud targets to discover:

    Under Discovered Targets, select the Exadata Cloud infrastructure host target to discover. The columns in the table like Deployment Type, and Target Already Managed can help you to select the right targets. For the Oracle Exadata Database Service on Cloud@Customer target, the deployment type is Cloud@Customer. For the Oracle Exadata Database Service on Dedicated Infrastructure target, the deployment type is Oracle Cloud Infrastructure. By default, the Target Type for the Exadata Cloud targets is Exadata Infrastructure.

  5. Provide the storage server details (Optional):

    If you have installed the monitoring agent on one of the VM cluster hosts before starting the discovery, then the button Set Storage Server Credentials is displayed in the column Storage Server Credentials. Click the button. The Set Storage Server Credentials dialog box opens.

    Under Storage Server Credentials, from the menu, select the named credentials associated with the storage server that you had identified as part of the prerequisite tasks.

    Under OCI VM Cluster, select the VM cluster which has the agent to monitor the storage server.

    Under Monitoring Mechanism, select from ExaCli or RESTful API. jf you selected RESTful API, then specify the HTTPS Protocol, and enable Trust Self-Signed Certificate if applicable.

    Click Save.

    At this point, based on your selection of Exadata Cloud infrastructure host target for discovery, all the underlying VM Clusters, Autonomous VM Clusters, and storage servers will automatically get discovered.

  6. At a later point, if there are more child targets added to the infrastructure target, then you can re-run the discovery process to include them.

    Click Next.

  7. Verify your selection of targets:

    Based on your selection of the infrastructure target in the prior step, a summary is displayed. If you provided the storage server details, then the Exadata Grid targets are also included in the summary.

    Click Submit to complete the discovery.

After the discovery process is complete, a summary of the discovery is displayed. All the targets and their discovery status can be noted. The target types listed are Oracle Exadata Storage Server Grid, Exadata Infrastructure, Oracle Exadata Storage Server, Exadata VM Cluster, and Autonomous Exadata VM Cluster.

To view the target home pages, click Show All Exadata Systems. The page Oracle Exadata Database Machines and Cloud Services is displayed.

Explore the Exadata Cloud Target Home Pages

After the discovery is complete, visit the home pages of Exadata Infrastructure target and explore the various views.
