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.

Phantom groups, MySQL queries and Jamf Pro 10.7

September 19, 2018 2 comments

On September 13th, Jamf released a new KBase article for Jamf Pro customers who hosted Jamf Pro themselves instead of hosting in Jamf Cloud:

On-Prem Jamf Pro Customers Upgrading to 10.7.0: https://www.jamf.com/jamf-nation/articles/552/on-prem-jamf-pro-customers-upgrading-to-10-7-0

In the KBase article, Jamf provides a couple of MySQL commands to run:

select computer_group_id,criteria,criteria_display from smart_computer_group_criteria where criteria not in (select computer_group_name from computer_groups) and search_field="Computer Group";
select computer_group_id,criteria,criteria_display from smart_computer_group_criteria where binary criteria not in (select binary computer_group_name from computer_groups) and search_field="Computer Group";

If either query returned data, the KBase directs you to contact Jamf Support. This was my output:

What had happened? For more details, please see below the jump.

As part of the KBase article, Apple included a Changes introduced in macOS Mojave section which featured this note:

You can allow apps to access certain files used for system administration, and to allow access to application data. For example, if an app requests access to your Calendar data, you can allow or deny the request. MDM administrators can manage these requests using the Privacy Preferences Policy Control payload, as documented in the Configuration Profile Reference.

Using directory membership to manage Apple Remote Desktop permissions

August 22, 2018 3 comments

Apple Remote Desktop (ARD) is a screen sharing and remote administration tool that just about every Mac admin uses at some point. Configuring access permissions for it can be done in several ways:

  1. Using System Preferences’ Sharing preference pane to configure the Remote Management settings.
  2. Using the kickstart command line utility to grant permissions to all or specified users
  3. Using the kickstart command line utility to grant permissions to members of specified directories.

The last item may be the least-known method of assigning permissions, but it can be the most powerful because it allows ARD’s management agent to be configured once then use group membership to assign ARD permissions. For more details, please see below the jump.
