Oracle Java JDK, OpenJDK, Java 11 and macOS

October 19, 2018 1 comment

With Java 8 approaching the end of its lifecycle, Oracle has made some changes to the Oracle JDK license that will affect Java 11’s JDK. As of Oracle Java JDK 8, you can use the JDK for free in the following circumstances:

  • Development
  • Testing
  • Prototyping
  • Production

As of Oracle Java JDK 11, you can use the JDK for free in the following circumstances:

  • Development
  • Testing
  • Prototyping

Notice that Production has dropped off the list? If you use Oracle Java JDK 11 for production use, Oracle is now expecting payment. For the complete details, please see the license agreement (relevant sections highlighted below):

If you don’t want to or can’t pay Oracle, what are the available options?

1. Keep using Oracle Java JDK 8

Oracle will continue to provide updates for Java 8 until January 2019, so a short-term solution is to keep using JDK 8 until support ends. This is only a short term solution however. If you want to continue using Java 8 past January 2019, you may need to start paying Oracle in order to get access to continuing Java 8 support.

2. Migrate from Oracle Java JDK to OpenJDK

In addition to its commercial offering, Oracle has an open-source Java available named OpenJDK. As of Java 11, Oracle will be providing functionally identical JDK builds to both the commercially licensed Oracle JDK and the open-source OpenJDK. For more details, please see below the jump:

Building an SAP GUI installer for macOS

October 11, 2018 2 comments

Since I’ve started working for my current employer, my colleagues and I have occasionally received the following question from various Mac admins:

“I’m using SAP in my environment. How do I deploy the Mac software for SAP?”

When we’ve followed up for more details, the “Mac software for SAP” usually means the SAP GUI software. SAP GUI comes in two flavors:

SAP GUI for Java supports the following operating systems:

  • openSUSE
  • Fedora
  • macOS
  • Microsoft Windows
  • AIX
  • Ubuntu

The SAP GUI for Java is what’s available for macOS, so how to get it and deploy it? For more details, please see below the jump.

Automating Jamf Infrastructure Manager setups on Red Hat Enterprise Linux

June 23, 2018 Leave a comment

As part of a project, I needed to build an automated setup process for a Jamf Infrastructure Manager (JIM). Thanks to the help of some folks at Jamf, I have a process which runs non-interactively and which does the following on Red Hat Enterprise Linux 7.x:

  1. Installs the JIM software
  2. Enrolls the JIM with a Jamf Pro server

Oracle Java 10 JDK and JRE installation scripts for macOS

April 19, 2018 1 comment

Oracle has started to release Java 10 for macOS, so I’m posting a couple of scripts to download and install the following:

Oracle has been releasing two separate versions of Java 8 simultaneously and may do the same for Java 10, so these Java 10-focused scripts are designed to allow the user to set which version they want to install: the CPU release or the PSU release.

The difference between CPU and PSU releases is as follows:

  • Critical Patch Update (CPU): contains both fixes to security vulnerabilities and critical bug fixes.
  • Patch Set Update (PSU): contains all the fixes in the corresponding CPU, plus additional fixes to non-critical problems.

For more details on the differences between CPU and PSU updates, please see the link below:

Automating Oracle Java 8 JDK updates

July 29, 2016 1 comment

To go along with a previous post about automating Oracle Java 8 updates, I’ve now posted a script to download and install the latest Java 8 Java Development Kit (JDK) from Oracle. Oracle has been releasing two separate versions of Java 8 simultaneously, so this script is designed to allow the user to set which version they want to install: the CPU release or the PSU release.
The difference between CPU and PSU releases is as follows:

  • Critical Patch Update (CPU): contains both fixes to security vulnerabilities and critical bug fixes.
  • Patch Set Update (PSU): contains all the fixes in the corresponding CPU, plus additional fixes to non-critical problems.

For more details on the differences between CPU and PSU updates, please see the link below:

Java 8 Update 65 Redux – The Good, the Bad and the Failings

November 13, 2015 Leave a comment

With the release of Java 8 Update 65, Oracle has returned to using an application to install Java. This switch away from using installer packages is a problem for Mac admins who need to deploy Oracle’s Java 8 in their own environment. However, after doing some research, it looks like it is still possible to deploy Oracle’s Java 8 Update 65 using a standard installer package. For more details, see below the jump.
