Java 8 to Java 11 Upgrade

Hi

we are planning to upgrade the Groundplex nodes from Java 8 to Java 11 as per the below instructions given on portal (applicable to our system)

  1. Stop the existing JCC node by running the following command:
    $ sudo /opt/snaplogic/bin/jcc.sh stop

  2. Download the new Snaplex installer and install the Groundplex, running the RPM, DEB, or Docker installers as appropriate.
    For RPM systems, run the following command:
    $ rpm -U snaplogic-snaplex.rpm

  3. Add the following entry to the /etc/sysconfig/jcc directory. You must create this directory and file if neither are present.
    export SL_JAVA_HOME=/opt/snaplogic/pkgs/jdk-11.0.1/

  4. Start the JCC node by running the following command:
    $ sudo /opt/snaplogic/bin/jcc.sh start.

however, I have confusion on point 3 as I am unclear what we exactly need to do here.
as we don’t have /jcc folder there I will create it but what permission we need to grant to that folder? permission should be given to which user?
what is the name and extension of the file we need to create here? do we need to put the given export statement inside it or its command?

please give more clarity on this point

    The /etc/sysconfig directory should contain a file named jcc with the contents

    export SL_JAVA_HOME=/opt/snaplogic/pkgs/jdk-11.0.1/

    The /etc/sysconfig directory and /etc/sysconfig/jcc file should be readable by everyone. One way to create the file would be

    sudo mkdir -p /etc/sysconfig; sudo sh -c "echo 'export SL_JAVA_HOME=/opt/snaplogic/pkgs/jdk-11.0.1/' >> /etc/sysconfig/jcc"

    We will update the documentation.

      Thanks Dave, i could see it in documentation also.

      Also can you tell how can we copy current cacerts files from current to new location using keytool utility with reference to below notes in documentation (we don’t have any additional customization to be done on the nodes )

      "
      To use custom truststore entries, you should back up the /opt/snaplogic/pkgs/jre1.8.0_162/lib/security/cacerts file and copy any additional custom truststore entries to the /opt/snaplogic/pkgs/jdk-11.0.1/lib/security/cacerts file using the keytool utility.
      "
      let me know if there is any command handy with you.
      thanks

        If there are no customizations to be done, then there is no need to copy any entries into the new JRE cacerts.

        In case there are new trust entries to be added, the command will be something like

        /opt/snaplogic/pkgs/jdk-11.0.1/bin/keytool -import -trustcacerts -keystore /opt/snaplogic/pkgs/jdk-11.0.1/lib/security/cacerts -storepass changeit -alias myalias -import -file mytrust.txt

        The command will change based on what format the trust certificate file is in.

    If we’ve installed custom server certificates, which the ground nodes present for triggered tasks and such (in /etc/snaplogic/jcc-serverkeys.jks), do we have to redo anything there?

      No change is required as part of the JRE upgrade for handling custom SSL certificates and certificates used for enhanced encryption.

    Okay, thanks! Got a question on this step:

    Download the new Snaplex installer and install the Groundplex, running the RPM, DEB, or Docker installers as appropriate.
    For RPM systems, run the following command:
    $ rpm -U snaplogic-snaplex.rpm

    I downloaded snaplogic-sidekick-4.master-6851-x86_64.rpm from my Manager UI, but when I run the following:

    rpm -U snaplogic-sidekick-4.master-6851-x86_64.rpm

    I get the following response, and the RPM update quits:

    package snaplogic-sidekick-1:4.mrc298-1.x86_64 (which is newer than snaplogic-sidekick-4.master_6851-1.x86_64) is already installed

    Any thoughts what this is about?

    FYI for others’ awareness -

    I opened a case with support, and they claim our original RPM of SnapLogic (on this particular machine) is “very old” (<3yr) when they used a different RPM versioning format, so the rpm -U (update) won’t work as documented. They say we need to completely uninstall the existing package and then reinstall the latest package, which means that not only do the CA certs have to be re-applied (planned), but also the SERVER certs (not planned), and probably have to redo the system service/init.d settings as well (not planned). And that process may vary on each machine, depending on the original RPM used to install on that specific machine (basically age of the original install) - even though everything is running latest release…

      This ended up having a simplier solution!

      rpm -U --force

      😀
