  2. Find all the running Talend services with the command systemctl | grep talend.
  3. Stop all Talend services with the command systemctl stop <service name>.
  4. Open update_java.sh with a text editor.
  5. Locate the variables in the script and set them as follows:

    TALEND_HOME=<Talend_home_folder> (for example: TALEND_HOME=/opt/Talend-7.3.1)

    PROD_VER=<Talend_version> (for example: PROD_VER=7.3.1)

    JAVA_HOME=<Java_home_folder> (for example: JAVA_HOME=/usr/lib/jvm/jre1.8.0_221)
