Tech Update – Oracle PeopleSoft Transitions to OpenSearch (Doc ID 2950040.1)
As Oracle says:
Over the years, we have seen search in PeopleTools shift with the technologies available in the industry. We initially started with Verity.we moved to Oracle SES (Secure Enterprise Search). During this period, search was largely restricted to navigation and certain specialized application data scenarios such as Job Search, etc. Next, we prepared for the transition to Elasticsearch. During this move, we put a lot more effort and focus on the Search Framework to make the switch of the backend ‘search engine’ as seamless as possible. Due to licensing changes introduced by Elastic (details here), Elasticsearch 7.10.0 and Kibana 7.10.0 will be the last versions used in PeopleTools and PeopleSoft applications. PeopleTools plans to deliver OpenSearch as the successor of Elasticsearch and Kibana, beginning with PeopleTools 8.60.07 and 8.59.21.
customers never really relied on Elastic to install or support ELK in PeopleSoft. It was packaged and managed entirely within PeopleTools. Similarly, OpenSearch (for search) and OpenSearch Dashboards (for analytics) are planned to be packaged (DPK) and managed as part of PeopleTools.
