CA Virtual Network Assurance
Issue/Introduction
When preparing to install CA Virtual Network Assurance (VNA). The documentation states:
-
- "Install 64-bit Java 8 as the default JDK. Ensure that java is in the path of the install user."
- What is the correct 64-Bit Java OpenJDK install to use?
- What are the path requirements and how should they be set?
Cause
Documentation is not clear on OpenJDK Java requirements for VNA installations.
Environment
All supported Virtual Network Assurance releases
Resolution
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.
- yum install java-1.8.0-openjdk-devel.x86_64
To set that as the default for system use by VNA we need to run the following as the root user.
- update-alternatives --display java
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.
