When configuring Decision Server Rules on WebSphere Liberty Profile, which archive needs to be deployed on the application server in order to enable hosted transparent decision services?

The Hosted Transparent Decision Service (HTDS) is a component of IBM Decision Server that exposes rulesets as standard web services (SOAP/WSDL and REST/WADL). To enable this functionality on a WebSphere Liberty Profile server, the DecisionService.war web application archive must be deployed. This archive contains the necessary servlets and configuration to generate web service endpoints for deployed rulesets, allowing client applications to invoke decision logic remotely without embedding Decision Server libraries.

A. DSService.war is not a standard archive name for any core component of IBM Operational Decision Manager.
B. HdtsService.war, while a logical abbreviation for the service, is not the correct, official name of the web archive provided by IBM.
C. DecisionRunner.war is an older name for the Rule Execution Server (RES) console (res.war), which is used for management and monitoring, not for exposing rulesets as web services.

1. IBM Operational Decision Manager V8.10.5 Documentation: In the section detailing the deployment of Decision Server components, the DecisionService.war is explicitly identified as the archive for this purpose.

Source: IBM Knowledge Center, "Deploying the Decision Server archives on a Liberty server".

Reference: "DecisionService.war: This web application is used to run rulesets as web services (transparent decision services)." This confirms that DecisionService.war provides the HTDS functionality.

2. IBM Operational Decision Manager V8.9 Documentation: The documentation for configuring a server profile for Decision Server Rules clearly lists the required archives and their functions.

Source: IBM Knowledge Center, "Reference: Archives for Decision Server Rules".

Reference: The table in this section lists DecisionService.war with the description "Hosted transparent decision services (HTDS)". This directly links the archive name to the service in the question.
