You should also be mindful about OpenJDK updates. Multiple concurrent major versions on the same server are fully supported (see below).įor businesses, this generally means that maintenance and updates to OpenJDK are handled by the infrastructure team (or someone with root access) instead of by the development team. Instead, it is installed via yum, dnf, or rpm, with yum being the recommended method.

OpenJDK, on the other hand, is not available as zip file (at time of writing). But I've seen this method used in production systems where the concern is OS changes breaking the application). (As a note, zip-file download method is harder to keep up to date and is thus generally not recommended.

Another approach is to download the rpm and install it. Sometimes the application development team will ship their application together with the JDK to the deployment teams. When it comes to running Oracle JDK on RHEL, a configuration that I've seen a number of times is to download Oracle JDK zip file, extract it to a particular folder and point the application to that JDK. This lets you use the same JDK for Linux and Windows. While this article is about OpenJDK on RHEL, I should also point out that OpenJDK for Windows can also be downloaded from. I'll also discuss the operations of Java applications (such as Red Hat JBoss Enterprise Application Platform (JBoss EAP) and other servers) on top of OpenJDK.

I'll go over the Red Hat support model and technical details of how to install, update, and run different OpenJDK versions on Red Hat Enterprise Linux (RHEL) 6 and 7 systems. In this article, I'll discuss: the technical and support implications of the migration, what developers and operations teams need to know, and solutions to potential challenges. (See also Oracle's blog entry & licensing).Īn alternative is to use OpenJDK and effort is underway to make them fully interchangeable. A number of companies who are currently using Oracle JDK in production are making the decision to switch to OpenJDK or have already done so.Īndrew Haley (Red Hat's Java Platform Lead Engineer) recently wrote a great article on the direction of OpenJDK. GPL + Classpath Exception licensed (free for any use, subject to that license) are current made available by Oracle through. = has announced that the Oracle JDK 8 builds released after Jan 2019 cease to be free for commercial use. To allow the Platform to control the Kafka instance on its local JMX port, add the following to the Pega Platform JVM parameters: With WebLogic default security configuration, despite Kafka JVM being correctly started and the JMX port being open and reachable (note it is local and bound to a localhost), the Pega Platform will indefinitely wait for the connection to the JMX port to complete successfully.
With the recent Oracle JDK versions (JDK 7 Update 131 or later/JDK 8 Update 121 or later) and WebLogic Server October 2017 PSU or later, WebLogic implements JEP 290 support which increases security on the Remote Method Invocation (RMI) (see Oracle Fusion Middleware - Configuring a Custom JEP 290 Deserialization Filter).Īfter starting the Kafka JVM, Pega Platform attempts to connect on local Kafka Java Management Extensions (JMX)port (default 9999) to control the instance.
