Virtualization on an ODA was introduced in March 2013 under release 2.5 on the ODA V1, and 2.5.5 on the X3-2
model. Oracle virtualization has been around for a while, but the implementation is customized and simplified on an
ODA. Instead of a separate virtual manager with a GUI console for managing VMs, their server pools, and networks,
all of the deployment and management steps have been built into the command-line oak appliance kit (
oakcli
)
utility. Accordingly Oracle, VM functionality has to be ported to ODAs, which means there is a development cycle with
functionality delivered according to a roadmap and timelines.
The ODA virtualization functionality may lag behind the mainstream Oracle VM product. Regardless, Oracle is
porting VM templates to ODAs. To keep up with the release cycle for supporting application templates, you can search
“Oracle Database Appliance Solution in a Box” to learn about the new ODA application solutions being deployed by
Oracle and its partners.
You have to remember that ODA virtualization implements VLANs created by your network team. They are not
created by the ODA. Configuration work has to be performed at the network switches connected to the ODA to enable
the virtual networks.
The key points to remember are that ODAs can implement virtual networks to support both the databases and
applications deployed on a virtualized ODA appliance. Design and planning are required to properly create the
networks for virtualized ODA solutions.
Summary
This chapter outlined the requirements for implementing the networks needed to support an ODA deployment. It
provided a list of available networks, IP addresses, and cabling requirements, and detailed the process for deploying
ODA networks.
The process for changing network information on an ODA after it has been deployed was outlined. Finally, some
of the considerations that have to be made in a virtualized ODA environment were discussed.
ODAs offer a “keep it simple” model for deploying the appliances, including the configuration and setup of the
networks. ODAs support the standard key Oracle Linux and hardware utilities for managing the appliance. As a result,
the management of the appliance is flexible, while offering additional options, such as the
GridInst.pl
script for
automating post deployment network changes.
