Abstract
Operational Decision Manager on Cloud 2024.07 uses Java 17 and Eclipse 4.30.
Content
Released in August 2024, Operational Decision Manager on Cloud (ODM on Cloud) 2024.07 uses Java 17 and Eclipse 4.30. The previous release of ODM on Cloud (2023.04) uses Java 8 and Eclipse 4.16. For the best experience, users must upgrade the Java and Eclipse installations that they use with ODM on Cloud.
ODM on Cloud 2024.07 includes integration with IBM Watson Machine Learning AI and improved editors for business rules, decision tables and ruleflows. These features depend on the new Java and Eclipse.
Decision services developed in the last version of ODM on Cloud can be migrated directly to the new version. There is no data loss, and the decision services work with Java 17. However, differences between Java 8 and Java 17 can result in errors during development and deployment.
Decision Server runtimes (HTDS)
Execution compatibility is maintained in the Decision Server runtimes (HTDS) for previous versions of the decision engine, especially the engines that support Java 8. The engine version is shown in the Decision Server console (Rule Execution Server), and depends on the ruleset compilation time. For the supported versions of the decision engine, see Upgrade of decision engine for Software as a Service offerings.
If you compile decision services in Rule Designer or deploy a decision service from Decision Center on the latest ODM on Cloud, be sure that it supports Java 17, especially it XOM resources.
Rule Designer
Each release of ODM on Cloud delivers a new version of Rule Designer. ODM on Cloud 2024.07 is based on IBM Operational Decision Manager (ODM) 9.0.0, and its Rule Designer uses Java 17 and Eclipse 4.30. Users must install Java 17 and Eclipse 4.30 to run the new Rule Designer.
Continued use of an older Rule Designer might result in conflicts with the components in ODM on Cloud 2024.07. Decision services developed in ODM on Cloud 2024.07 cannot be synced with older versions of Rule Designer without producing errors.
Decision Center and Rule Execution Server
The cloud components in ODM on Cloud 2024.07 use Java 17. Decision services developed in the Decision Center Business console are based on Java 17, and rulesets republished from Decision Center rely on Java 17 and decision engine 1.70.x..
For example, a decision service with a Java 8 XOM is incompatible with Java 17. If it is republished to the new Decision Center, it will create build issue when it is deployed to Rule Execution Server.
