Oracle Database Appliance Discovery Prerequisites

Before you begin the discovery process, verify that the prerequisites are completed to ensure a smooth discovery.

Ensure that the following prerequisites are completed on your appliance:

  • Install agents on Oracle Database Appliance.

    • On bare-metal deployments, the agent must be deployed on each node.

    • On virtualized platform deployments, the agent must be deployed on each node in ODA_BASE.

  • Deploy the Oracle Database Appliance plug-in on the agents.

  • If you are using Oracle Database Appliance Virtualized Platform, then you can deploy the Oracle Virtualized Infrastructure Plug-In to monitor running virtual machines and view the Hypervisor statistics.

  • Ensure that the server node host names in each individual Oracle Database Appliance have a unique name within the enterprise.

Discovering Oracle Database Appliance with Oracle Enterprise Manager

Use this procedure to add hardware components as managed targets for Oracle Enterprise Manager.

The Oracle Database Appliance discovery process enables you to add the hardware components (such as compute node ILOM) in the Oracle Database Appliance as managed targets for Oracle Enterprise Manager. You already should have server nodes added as host targets. You add these host targets as members of the Oracle Database Appliance system target after the discovery process.

  1. From the Oracle Enterprise Manager home page, open the Setup menu (gear icon) in the menu bar, select Add Target, then Add Targets Manually.
  2. Select the Add Using Guided Process option.
  3. Under Guided Discovery, select Oracle Database Appliance and click Add.

    Oracle Enterprise Manager displays the Oracle Database Appliance Discovery page.

  4. Click Discover Now.
  5. On the Agent URL page, enter the following information and click Next:

    • Agent URL: Click the Browse icon and select an Oracle Database Appliance agent from the list. Click Select.

    • Credential: Select New and configure the root credentials for Oracle Database Appliance Discovery. Check the Save As box to give this credential a name for future use.

    The Discovered Targets page opens and shows detail about the system.

  6. (Optional) On the Discovered Targets page, you can choose to edit the fields. Click Next when you have completed editing.
  7. On the Credentials page, use the credentials you configured or used in Step 4. Uncheck the Same as the first one check box if the password is different on each node, and then click Next.
  8. (Optional) On the Tag Cloud page, you can select existing tags. or create new ones to associate with the discovered system. You can also configure tags in the Oracle Database Appliance home page.

    The Add Tag button is located at the bottom of the page under the list of available tags.

  9. On the Review page, verify each section is correct. Click Back to return to previous pages.
  10. If the information on the Review page is correct, click Submit.
  11. On the Target Creation Summary page, click OK.

Discovering Oracle Database Appliance Virtualized Platform with Oracle Enterprise Manager

If you have deployed Oracle Database Appliance Virtualized Platform, then complete this procedure to discover the Hypervisor and Virtual Servers.

  1. From the Oracle Enterprise Manager home page, clickSetup (gear icon) in the menu bar, select Add Target, and then select Add Targets Manually.
  2. In the Add Targets Manually page, select Add Using Guided Process and choose the Oracle Virtual Platform target type.
  3. Click Add.
  4. On the Discover Oracle Virtual Platforms page, specify the default Monitoring Agent and Credentials for the Oracle Virtual Platforms that you want to discover.

    • In the Monitoring Agent field, click the search icon (magnifying glass) to search and select the default monitoring agent for monitoring targets. The default agent is typically the agent that is deployed in the ODA_BASE domain on Node 0. Click Select.

    • (Optional) Enter a failover monitoring agent. The failover monitoring agent is the standby monitoring agent for monitoring targets, which typically is the ODA_BASE agent on Node 1.

    • Enter the user name and password for the Oracle Database Appliance DOM0 server.

  5. Specify the host name or IP address for the Oracle Virtual Manager servers that you want to discover.

    • In the Hostname and IP Address section of the page, click Add.

    • In the Discover Virtual Servers dialog, enter the Dom0 node names. Specify a long host name (fully qualified domain name, or FQDN), or specify an IP address. To enter multiple entries, enter each new host name, IP address or IP address range in a new line.

    • Click Add.

  6. After you finish entering information on the Discover Oracle Virtual Platforms page, click Submit.

    After the job completes, it may take a few minutes for the targets to become visible under the Oracle Database Appliance target.

Discovering Oracle Grid Infrastructure and Oracle RAC Targets

To add targets to be monitored by Oracle Enterprise Manager, you must first specify the host on which those targets reside.

The host targets and the corresponding Oracle High Availability Service targets are added as members of the cluster during the discovery process.

Discover Oracle Grid Infrastructure (Cluster) Targets

Use this procedure to discover Oracle Grid Infrastructure targets.

Oracle Clusterware and High Availability Services require that you add the targets using this Oracle Enterprise Manager Cloud Control procedure.

  1. From the Oracle Enterprise Manager home page, open the Setup menu (gear icon) in the menu bar, select Add Target, then Add Targets Manually.
  2. Select Add Using Guided Process.
  3. Select Oracle Cluster and High Availability Service from the Guided Discovery list, and click Add.
  4. In the Specify Host field, click the search icon (magnifying glass) and select a host target. Click Select. The selected host displays in the Specify Host field.
  5. Click Discover Target. The cluster home details are displayed in the Add Target: Cluster and Oracle High Availability Service page.
  6. Edit cluster target properties if needed, and click Update.
  7. Ensure that all database nodes are shown in the Cluster Host and High Availability Services Targets section.
  8. Click Discover Target in the upper right corner of the page.

Discover Oracle Real Application Clusters Targets

Use this procedure to add Oracle Real Application Clusters (Oracle RAC) databases as targets.

You can add databases, listeners, and Automated Storage Managers (ASM) as monitored targets. A monitored target is an entity that you want to monitor and administer using Oracle Enterprise Manager. Oracle Enterprise Manager will search for targets of these types on the host or cluster that you specify.

  1. From the Oracle Enterprise Manager home page, clickSetup menu (gear icon), select Add Target, and then Add Targets Manually.
  2. Select Add Using Guided Process.
  3. Select Oracle Database, Listener and Automatic Storage Management from the Guided Discovery list, and click Add.
  4. Follow the instructions in the wizard.
  5. In the wizard pages, configure Cluster Databases (dbsnmp password required) and Cluster ASM (asmsnmp password required).

Removing an Oracle Database Appliance Target

Use this procedure to remove Oracle Database Appliance targets from Oracle Enterprise Manager Cloud Control 13c.

Use the following procedure to remove an Oracle Database Appliance Target:

  1. From the Oracle Enterprise Manager home page, Click Target (target icon) in the menu bar, and select All Targets.
  2. In the All Targets page, in the navigation tree, find and expand the Engineered Systems category.
  3. Click Oracle Database Appliance System.
  4. In the right pane, click on the name of the target you want to remove. A context menu opens.
  5. From the Oracle Database Appliance System drop-down menu (top left corner of page), select Target Setup, and then Remove Target. A confirmation dialog box opens so that you can confirm the target deletion. Click Yes to continue.
