Implementing Fail-over Mechanism Using Multiple Nodes Feature of OpenSearch

When you configure PeopleSoft Search Framework with OpenSearch, PeopleSoft Search Framework enables you to implement a fail-over mechanism.

When you use the multiple-nodes option and when you deploy search definitions/categories and generate indexes, OpenSearch automatically distributes the indexed data to the nodes based on its constructs of primary shards and replica shards.

You can create multiple nodes on the same machine or on different machines. If you are creating nodes on different machines, but want the nodes to be on the same cluster, refer to the OpenSearch documentation for information on how you can complete the setup.

To create another node using the installation instructions, refer to PeopleSoft Deployment Packages Installation for Search Components for the current release.

Complete these steps to set up multiple nodes in a search instance:

  1. After Installing the search engine, you need to configure the search functionality.

  2. Use PIA to configure the PeopleSoft Search Framework by creating a search instance.

  3. Enter information in the required fields and save the search instance.

  4. Install another node on the same machine or on a different machine. Follow the instructions in the PeopleSoft Deployment Packages Installation for Search Components for the current release.

  5. Reopen the search instance and In the Search Instance Properties grid, add the newly created node.

  6. Enter information in the required fields to point to the new node and save the search instance.

    Note:

    In a multi-node OpenSearch cluster, always ensure that the replica value is set to at least 1. For details, see Managing General Search Options.

  7. Deploy the search definitions/categories and generate indexes for the search instance.

Note:

In a multi-node cluster, for the cluster to be available, ensure that you do not stop half or more of the nodes in the voting configuration at the same time.

Your search functionality is complete and ready for use. In the event that a node fails, PeopleSoft Search Framework automatically points searches to an active node of the search instance.
