- Install the latest version of Java 8 or 11 on each dedicated physical or virtual machines.If the correct version of Java is not automatically detected, you can set the path to the Java home directory in /etc/opt/teradata/tdqgm/setenv.sh after installing the tdqg-manager rpm.For example:
export TDQGM_JAVA_HOME=/usr/java/jdk1.8.0_101
- Download required package (file name tdqg-manager-version.rpm).
