Open edition

The open edition installer package names provide platform and Java version information in the following formats:

ibm-semeru-open-<jdk|jre>_<architecture>_<operating system>_<openjdk level>_openj9-<openj9 level>.<extension>

For example, the IBM Semeru Runtime Open Edition for Linux® on 64-bit IBM POWER® systems (little endian), Java version 11.0.12 build 7, has the following package name: ibm-semeru-open-jdk_ppc64le_linux_11.0.12_7_openj9-0.27.0.tar.gz.

To check whether the java executable that you are using is from an open edition run the java -version command. The following example shows the output from the IBM Semeru Runtime Open Edition:

   openjdk version "11.0.12" 2021-07-20
   IBM Semeru Runtime Open Edition 11.0.12.0 (build 11.0.12+7)
   ...
                                

Certified edition

The installer package name of the certified edition provides platform and product version information in the following formats:

ibm-semeru-certified-<jdk|jre>_<architecture>_<operating system>_<semeru version>.<extension>

For example, the IBM Semeru Runtime Certified Edition for Linux® on 64-bit IBM POWER® systems (little endian), Java version 11.0.12 build 7, has the following package name: ibm-semeru-certified-jdk_ppc64le_linux_11.0.12.0.tar.gz.

To check whether the java executable that you are using is from a certified edition run the java -version command. The following example shows the output from the IBM Semeru Runtime Certified Edition:

   java version “11.0.12” 2021-07-20
   IBM Semeru Runtime Certified Edition 11.0.12.0 (build 11.0.12+7)
   ...
                                

The version number of the certified edition package is based on the version of the underlying OpenJDK release. A refresh which does not coincide with a new OpenJDK release will result in the certified edition version incrementing by one.

For example, the initial release based on OpenJDK version 11.0.12 would have a version number 11.0.12.0. The following release for an IBM update based on a security fix would have a version number 11.0.12.1.

IBM is working to host a RESTful API server that uses the new Eclipse Adoptium™ OpenAPI definition. Until that is ready we offer the IBM Semeru Runtime Open Edition from the RESTful API provided by the AdoptOpenJDK community, and follow the AdoptOpenJDK OpenAPI definition.

When using the AdoptOpenJDK API service to retrieve IBM Semeru Runtimes use "ibm" for the vendor field (vendor) and "openj9" for the JVM implementation field (jvm_impl).

Examples:

• List the IBM Semeru Runtimes release names:

  https://api.adoptopenjdk.net/v3/info/release_names?vendor=ibm

• List the available IBM Semeru Runtimes versions:

  https://api.adoptopenjdk.net/v3/info/release_versions?jvm_impl=openj9&project=jdk&release_type=ga&vendor=ibm

• List the developer kit packages in the 11.0.12 release:

  https://api.adoptopenjdk.net/v3/assets/version/11.0.12%2B7?image_type=jdk&jvm_impl=openj9&project=jdk&release_type=ga&vendor=ibm

• Download the latest version 11 Linux x64 package by using curl:

  curl -OLJk "https://api.adoptopenjdk.net/v3/binary/latest/11/ga/linux/x64/jdk/openj9/normal/adoptopenjdk?project=jdk"

Note: The base url used in these examples will change once the IBM RESTful API is released.
