The Snaplex Linux installers include a bundled OpenJDK-based JRE 11 distribution. You can follow the instructions in this document to change the Java version on your Linux and Windows Snaplex instances. You might need to change the Java version to update the JRE in order to receive security and functionality fixes in the newer JRE distribution. Even if your organization has a license for a different JRE distribution, you can use the procedure in this article to configure the Groundplex to use the said JRE.

Updating JRE Version by Installing a New SnapLogic RPM/DEB on Linux

...

The Snaplex installer defaults to openjdk-11.0.12+7-jre. To update to a JRE installed at another location, create a file /etc/sysconfig/jcc with SL_JAVA_HOME pointing to the desired JRE location.

To create the /etc/sysconfig directory and /etc/sysconfig/jcc file as well as grant read permissions to all users, run the following command:

...

1. In the Windows command prompt, stop the JCC node by running the following command:
   c:\opt\snaplogic\bin\jcc.bat stop
   This step is required if there is an existing Snaplex installation on the node.
   
   
2. Download the new installer Zip and extract the contents to the following location:
    c:\opt\snaplogic


3. Download and install the Adoptium's OpenJDK-based Java 11 installer.
   
   
4. Update the c:\opt\snaplogic\bin\jcc.bat file and update the JAVA_HOME to point to the location of the Java 11 installation.
   
   
5. Start the JCC nodes:

   1. If you are running the Snaplex as a service, run the following commands: 
      jcc.bat remove_service
jcc.bat install_service

      
      

   2. Run the following command:

      c:\opt\snaplogic\bin\jcc.bat start

After you configure Java, go to the SnapLogic Dashboard and verify that the Additional Information dropdown list displays the Java version as 11.0.12+7 or higher.
