Java Runtime Environment

Any of the following Java™ Runtime Environments must be installed on your machine:
Important:
  • IBM® AD now supports Java versions 8 and 11. When you install IBM AD, make sure to uninstall any existing Java version that was installed if it is not a supported one. The minimum patch level that is required for Java 1.8 is 1.8.0_361, and for Java 11, it is 11.0.11. To ensure that IBM AD will work properly, you must install at least the minimum supported patch version accordingly.
  • IBM AD Build Client runs only on the 64-bit JVM.
  • 64-bit AdoptOpenJDK 8/11 HotSpot - https://adoptium.net/
    Important:
    • Make sure to download the JRE version of AdoptOpenJDK for the target platform.
    • Make sure that Set JAVA_HOME variable and JavaSoft (Oracle) registry keys subfeatures are selected when you install AdoptOpenJDK Development Kit with Hotspot.
  • 64-bit Java 8/11 Oracle
  • 64-bit Java 8/11 IBM - https://developer.ibm.com/javasdk/downloads/
    Note:
    • On Windows
      Since there is no executable for IBM Java, it needs to be unzipped, and you need to set the IBM Java path in Windows Registry.
      Important: IBM AD installer is looking in Windows Registry to find out the IBM Java path. Use extreme caution when you edit the Windows Registry. Incorrect edits can render your computer unusable.
      1. Create the following path: Computer > HKEY_LOCAL_MACHINE > SOFTWARE > JavaSoft > Java Development Kit > 1.8.
      2. Right-click 1.8, and then select New > String Value.
      3. Rename New Value #1 to JavaHome.
      4. Right-click JavaHome, and then select Modify.
      5. In Value data, enter the path to the unzipped IBM Java folder.

        Note: ibm_sdk80 represents the IBM Java version that is used during the installation process.
      6. If you installed IBM Semeru and need to use Db2® for LUW and test the connection on the relational database page, go to Start > System > Advanced Settings > Environment Variables > System variables, and click New. Then, enter JAVA_TOOL_OPTIONS in the Variable name field, enter -Dcom.ibm.jsse2.sp800-131=strict in the Variable value field, and click OK.
      7. Restart the Windows machine so that the changes can take effect.
Important: Make sure that the path for Java is set in your system as follows: Start > System > Advanced Settings > Environment Variables > System variables > Path. The path to the Java installation folder must be set to include the bin folder as in C:\Program Files\Java\jre1.8.0_171\bin.
