Java version 17 is not installed. Please install Java 17.
A problem occurred during installation (install directory not deleted). Backing up to /opt/install/CA_VNA_Install_bak
Can this work with JAVA 11?? We are having trouble getting JAVA 17 for RH7
VNA/SDX 23.3.3 and later
java 17 is required for 23.3.3 and higher
Java 17 should work fine even though it will likely not be in the RHEL 7 yum repository
The required Java 17 JDK can be downloaded from:
https://adoptium.net/temurin/releases/?version=17&arch=x64&os=linux
Make sure to download the JDK not JRE.
The following is an example of using this JDK:
1. Download the java 17 tar.gz or below is an example of using wget to do it directly. Note there may be newer versions available, this is just an example:
# wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.9%2B9/OpenJDK17U-jdk_x64_linux_hotspot_17.0.9_9.tar.gz
2. Extract it into a directory
# tar -xvf OpenJDK17U-jdk_x64_linux_hotspot_17.0.9_9.tar.gz --directory /opt/jdk-17.0.9+93. Update alternatives to include the downloaded version of java
3. Change directory
# cd jdk-17.0.9+9
4. Update alternatives
# update-alternatives --install /usr/bin/java java $(pwd)/bin/java 0
5. Set the java version to 17 using:
# alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
