Prerequisites for Creating a Connection

You must satisfy the following prerequisites to create a connection with the OpenSearch Adapter:

Create an OCI Search with OpenSearch Cluster in the Oracle Cloud Console

  1. Sign in to the Oracle Cloud Console.
  2. Under Databases, select Clusters.


    In the left navigation pane, the Databases is selected. On the Databases page that is displayed, the OpenSearch section shows that the Clusters option is selected.

  3. Click Create Cluster. See Creating an OpenSearch Cluster.

    You configure the OCI Search with OpenSearch cluster to be associated with a VCN and subnet of your choice. You also create admin user/password credentials. In the database world, this configuration is equivalent to creating an Oracle26ai instance and setting up the wallet.


    The Clusters page shows a Create Cluster button and a Search by name button. Below this is a table with columns for Name, State, Storage (GB), Software version, and Created.

    Note:

    Create the OCI Search with OpenSearch cluster in a private or public subnet. Common configurations are:
    • Create your OpenSearch cluster in your selected VCN's private subnet and use a private endpoint to access OpenSearch in Oracle Integration. This configuration ensures that your access remains private inside the Oracle network. See Configure a Private Endpoint for Your Instance in Provisioning and Administering Oracle Integration 3.
    • Create your OpenSearch cluster in your selected VCN's private or public subnet and use a VM with nginx in your VCN's public subnet to forward the requests to your OpenSearch cluster. The connection URL you use in the OpenSearch Adapter must point to the virtual machine (VM) running nginx. See Access OCI OpenSearch Dashboards and REST APIs outside a VCN and nginx.

    When configuration is complete, the OCI Search with OpenSearch cluster instance details are provided. For this example, the cluster is created in a private subnet, meaning your OCI Search with OpenSearch activity can remain private.


    The Cluster details page shows tabs for Resize, Create backup, Restore, Upgrade, Create RAG Pipeline, and More actions. Below this the Cluster information tab is selected. This tab shows sections for Cluster details and Network details. On the left a green circle labeled Active is shown.

    When you create an OpenSearch Adapter invoke connection on the Connections page, you specify the URL associated with the cluster and the Basic Authentication admin user/password configured while creating the cluster. See Configure Connection Properties.
