About Oracle WebLogic Server and Coherence on GraalVM Enterprise Edition
Oracle WebLogic Server and Coherence 12c (18.104.22.168.0) are certified to run on Oracle GraalVM Enterprise Edition.
Oracle GraalVM Enterprise Edition is a high performance runtime platform built on Oracle's enterprise-class Java SE. Its optimizing compiler accelerates WebLogic applications by rearranging compiled code, aggressive method inlining, escape analysis, advanced vectorization and more. Running WebLogic Server and Coherence on GraalVM Enterprise is as simple as updating your
PATH environment variables and calling

For details on system configuration supported by Oracle WebLogic Server and Coherence, see Oracle Fusion Middleware Supported System Configurations.
When you run WebLogic Server and Coherence applications on Oracle GraalVM Enterprise, in general you can anticipate up to a 5-10% performance improvement. This performance improvement estimate is based on a variety of internal API specific microbenchmarks, and benchmarks run on a full, end to end Java EE WebLogic Server application used for internal stress testing. This application covers a combination of Java EE APIs and is run in a large clustered configuration. These performance improvement results, which are consistent with performance improvements observed for other Java applications, and improvements observed for other Oracle applications, are the basis for these estimates. Performance benefits will be application-specific, and we encourage testing on your applications to verify the benefits you will realize from Oracle GraalVM Enterprise.
