When preparing to install CA Virtual Network Assurance (VNA). The documentation states:
Documentation is not clear on OpenJDK Java requirements for VNA installations.
All supported Virtual Network Assurance releases
The correct Java 8 JDK to install is the java-1.8.0-openjdk-devel.x86_64 : OpenJDK Development Environment package. In most instances the following command run as root will install the required package.
To set that as the default for system use by VNA we need to run the following as the root user.
With the correct JDK installed and now set as the system default, no PATH variable changes should be necessary. When VNA starts it will find the default Java on the system, the required JDK, and should function normally.
