Add Connections

You must add connections to the External Database System components to enable Database Management to monitor the component.

Connections can be added to the components in the External Database System during the discovery process or later from the details pages of the components. The topics in this section provide information on how to add connections to components (other than databases) as part of the External Database System discovery process. The process to add connections to databases in the Database Management interface is the same as in the External Database service. For information, see Create a Connection to an External Database.

Add Connections to Clusters

  1. On the Managed databases page, click Discover system and then click External Database System to start the External Database System discovery process. For information, see Discover External Database Systems.
  2. On the Select components page of the Discover External Database System panel, scroll down to the Cluster section, and click Add connection in the Connection column.
  3. In the Add connection panel:
    1. Provide connector information:
      1. Connector display name: Optionally, edit the default name assigned to the connector to easily identify the connector.
      2. Agent: Select the Management Agent installed on the respective cluster node to establish a connection with the cluster.
        Note

        To connect to and monitor clusters, the mgmt_agent user must be available on all the nodes in the cluster. For more information, see Perform Prerequisite Tasks.
    2. Click Add connection.
If there are more cluster nodes, then follow the same process to add connections.

Add Connections to ASM

  1. On the Managed databases page, click Discover system and then click External Database System to start the External Database System discovery process. For information, see Discover External Database Systems.
  2. On the Select components page of the Discover External Database System panel, scroll down to the ASM section, and click Add connection in the Connection column.
  3. In the Add connection panel:
    1. Provide connector information:
      • Connector display name: Optionally, edit the default name assigned to the connector to easily identify the connector.
      • Agent: Select the Management Agent to establish a connection with ASM.
    2. Specify connection string information:
      1. ASM hostname: Specify the host where the ASM instance is installed. Note that you can add comma-separated host names of the ASM instances.
      2. Port: Specify the port number.
      3. ASM service: Specify the service name.
      4. Protocol: Select either the TCP or TCPS protocol to connect to ASM.
      5. TLS wallet secret: Select the secret that contains the Oracle wallet from the drop-down list. This field is only displayed if TCPS is selected in the Protocol field. If an existing wallet secret is not available, then select Create new secret... in the drop-down list. The Create TLS secret panel is displayed and you can create a new secret. For information on Oracle wallets and creating a secret in the Vault service, see Perform Prerequisite Tasks.
    3. Specify the credentials required to connect to ASM in the External Database System:
      1. User name: Enter the user name to connect to ASM. It's recommended that you use the default ASMSNMP user or any user with both the SYSASM and SYSDBA privileges.
      2. ASM user password secret: Select the Oracle Cloud Infrastructure Vault service secret that contains the ASM user password. If an existing secret with the ASM user password is not available, then select Create new secret... in the drop-down list. The Create password secret panel is displayed and you can create a new secret. For information on how to save the ASM user password as a secret in the Vault service, see Perform Prerequisite Tasks.
      3. Role: Select the role from the available options.
      4. Credential name prefix: Specify the first part of the full credential name. This value is prefixed to a system-generated credential name to create the full credential name.
      5. Credential name: (Read-only) Credential name of the connection.
    4. Click Add connection.
