The number of required licenses shall be determined by multiplying the total number of cores of the processor by a core processor licensing factor specified on the Oracle Processor Core Factor Table.Īccording to the new policy you have to make constant calculations of the number of CPUs, users, cores, etc. Processor is defined as all processors where the Oracle programs are installed and/or running.

We’ve assessed all JDK builds using the following criteria: Here is the full list of JDK builds we’ve researched: The most popular and famous builds are distributed by Red Hat, Azul and community-led Adopt OpenJDK. If an organization produces an OpenJDK build that passes the TCK then that build can be described as “Java SE compatible”. This certification is run by the Java Community Process, which provides a Technology Compatibility Kit (TCK or JCK as Java). So, Oracle created a certification process that should be used to ensure the build is valid. It is hosted in Mercurial at OpenJDK.Īnyone can take the source code, produce a build, and post it.

JDK buildsīasically, there is only one set of source code for the JDK. Most of them have different support models (free and paid for), and different attitudes toward providing updates for multiple Java versions.Īs Oracle is not the only vendor in this game, it’s time to look beyond their JDK.ĭevexperts is happy to share with you the results of our research. The changes to the Oracle licenses forced us to look for other JDK vendors.
