1. Which OpsRamp application or service requires Java?
The vProbe application, a core component of the NextGen Gateway, requires Java. vProbe performs discovery and monitoring operations on your system.
2. Do you need to install Java on your host system for the NextGen Gateway?
No. You do not need to install Java on your host system.
In the NextGen Gateway:
- vProbe runs inside a containerized (Kubernetes‑based) environment on your infrastructure
- Java is pre‑bundled within the container image
3. Which Java version does your NextGen Gateway use?
The Java runtime used by your NextGen Gateway is embedded within the container image and aligned with gateway release compatibility. From Gateway version 21.0.0 onward, your deployment uses Java 17.
4. Can you run the NextGen Gateway with a lower Java version?
No configuration is required at your host level. Java version management is handled internally within the container image automatically for you.
5. Can you remove Java from your host server for the NextGen Gateway?
Yes. You can safely remove Java from your host server since Java is included inside the container.
You can safely remove Java when running:
- Your customer‑managed Kubernetes clusters
- OpsRamp ISO/OVA images that do not bundle host‑level Java
Additional recommendations for your NextGen Gateway
- Do not install or manage Java on your host for NextGen Gateway use cases.
- Rely on the container‑bundled Java runtime to ensure compatibility and support for your deployment.
