Access to Oracle Java SE, including updates, is available via the “Oracle Java” channels in the Red Hat Customer Portal and is subject to the licensing obligations set forth in the applicable end user license agreement. IBM Java SDK is subject to the licensing obligations set forth in the applicable IBM end user license agreement. IBM Java is available via the Supplementary media, RHN channels, and Red Hat Customer Portal.In the interest of securing customer choice, Red Hat has agreements with Oracle and IBM to include both Oracle Java SE and IBM Java SDK with Red Hat Enterprise Linux.The Oracle Java SE license terms do not apply to OpenJDK.Īll Red Hat products are supported on Red Hat build of OpenJDK, however, not all are supported on other builds of OpenJDK, see the solution Red Hat OpenJDK vs AdoptJDK vs IBM Semeru for more details. Since OpenJDK is licensed under GPLv2, users of OpenJDK receive the rights and obligations under that license.Starting with OpenJDK 8, Red Hat also makes available and supports OpenJDK on Microsoft Windows to enable the development of Windows applications in conjunction with Red Hat JBoss Middleware.OpenJDK has a long history of support at Red Hat dating back to 2007 (see Red Hat Helps Advance Open Source Java), and Red Hat is a longstanding and senior member of the OpenJDK project.Red Hat Enterprise Linux includes OpenJDK as the default Java development and runtime environment.OpenJDK is the open source reference implementation of the Java SE specification and contains similar features to Oracle Java SE.This document provides an overview of the Java related options Red Hat offers its customers. Starting in 2013, when the new lifecycle policy for Oracle JDK 6 End of Public Updates was introduced, a number of articles and questions have been raised about Java’s ongoing status in the marketplace. Red Hat has a long history of providing Java with Red Hat Enterprise Linux and with our JBoss Middleware portfolio. Red Hat JBoss Enterprise Application Platform (EAP) 7 Supported Configurations has precedence - given it is feed directly by PM/Prod Eng more frequently. An increase of 1.5 times can be used as a guideline, but should be evaluated versus your SLAs.The article Red Hat JBoss Enterprise Application Platform (EAP) 7 Supported Configurations has precedence over the description below. So, when migrating a system from a 32-bit to 64-bit environment, the amount of memory has to be increased to achieve the same performance. This applies to all Java environments, whether they are running JVMs from other vendors or an Azul Zulu Prime JVM instance.Īdditionally, the increased efficiency of the garbage collector on a 64-bit system, also requires additional space relative to a 32-bit system. The result is that proportionally more memory is used to accommodate the same number of objects on a 64-bit system. Though primitives such as integers use 32-bit words on either a 32-bit or 64-bit system, Java object headers and pointers use 32-bits on a 32-bit system and 64-bits on a 64-bit system. Java heap memory requirements for 64-bit systems are generally 1.5 times greater than 32-bit systems. So, when determining the amount of Java heap memory to allocate, remember there is a difference in memory use in a 32-bit or 64-bit system.
