Understanding the OSK DPK Installation

The OSK DPK zip file includes a setup script, psft-dpk-setup.bat for the Microsoft Windows DPK and psft-dpk-setup.sh for the Linux DPK. Include the following decisions in preparing to install with the OSK DPK setup script:

• Run the script interactively, or run it in silent mode with a prepared configuration file.

• You also have the option to run in deploy-only mode, which installs the software components without connecting to a running PeopleTools mid-tier.

• Install OpenSearch and OpenSearch Dashboards together or separately.

• If you choose to install OpenSearch Dashboards at the same time as you install OpenSearch, the OSK DPK setup script prompts you to specify the OpenSearch server that you want to connect to OpenSearch Dashboards.

  You can connect to the server that you are in the process of installing, or enter the credentials for a different OpenSearch server.

• If you choose to install OpenSearch Dashboards at a different time, you must have an existing OpenSearch server to connect to.

  For example, you could install OpenSearch first on server1, and then at a later date install OpenSearch Dashboards on server2, and specify the OpenSearch installation on server1.

• Install Logstash after you install OpenSearch and OpenSearch Dashboards.

  Installing Logstash at the same time as OpenSearch and OpenSearch Dashboards may lead to problems with displaying certain OpenSearch Dashboards dashboards, such as those for CPU utilization.

• You can use the same Logstash installation for both PeopleSoft Health Center and external data integration.

• You have the option to use the PeopleTools Middleware DPK to install the latest Java version as part of a new installation.

• Specify OpenSearch clusters and nodes.

  The OpenSearch deployment creates an OpenSearch cluster with one or more OpenSearch nodes. Briefly, an OpenSearch node refers to the server where OpenSearch is installed, and the cluster is comprised of nodes which all have the same cluster name. The DPK setup script asks for the cluster name and the names of existing nodes. If you provide an existing cluster name and list of existing nodes, the existing nodes will join the cluster.

  You also have the option of supplying the names for master-eligible nodes during the installation for cluster configuration.

  For information on adding additional nodes after installation, see the section Adding Additional OpenSearch Nodes.

  See "Performing Additional Tasks," Adding Additional OpenSearch Nodes.

• See the requirements and recommendations for Logstash in the section Preparing for the Logstash Installation.

• When using the OSK DPK setup script:

  • The user who installs the OSK DPK owns all the OpenSearch files, and only that user will be able to start the process.

  • The installation does not require root access (on Linux) or administrator access (on Microsoft Windows).

• As part of the installation, models for semantic search are installed and registered to OpenSearch.

  You also have the option of doing the model registration and deployment manually. See Deploying Semantic Search Models Manually
