How to Create Clones and Snap Clones of a Template
Review these topics for an overview of clones and snap clones, and for procedures to
use to create clones.
•
About Creating Clones and Snap Clones of a Template
You can create, or clone, virtual machines from imported templates (or
assemblies) or from an existing virtual machine on Oracle Database Appliance
Virtualized Platforms.
•
Cloning a Template With OAKCLI
Use the
oakcli clone vm
command to clone virtual machines that have
attached virtual disks on Oracle Database Appliance Virtualized Platforms.
•
Creating a Snap Clone from a Template With OAKCLI
Use the
oakcli clone vm
command to create a snap clone of a virtual machine
template on Oracle Database Appliance Virtualized Platforms.
•
Creating a Snap Clone of an Existing Virtual Machine With OAKCLI
Use the
oakcli clone vm
command to create a snap clone of an existing
virtual machine on Oracle Database Appliance Virtualized Platforms.
About Creating Clones and Snap Clones of a Template
You can create, or clone, virtual machines from imported templates (or assemblies) or
from an existing virtual machine on Oracle Database Appliance Virtualized Platforms.
Clones and snap clones can be an effective way to provision and clone new
databases for test and development systems. They are much more efficient to create
than using RMAN scripts, or other cloning approaches.
You can create virtual machines that are a complete clone of the template or
assembly, or you can create virtual machines that are snap clones. Snap clones
contain only the metadata defined for the virtual machine.
Creating snap clones is a very fast operation compared to cloning the entire template
or assembly. However, if you update the contents of a snap clone, then review your
space requirements. Unless your changes to the snap clone are carried out on shared
virtual disks, you require additional storage on your system for the clone to retain both
the original content, as well as changed content.
Cloning a Template With OAKCLI
Use the
oakcli clone vm
command to clone virtual machines that have attached
virtual disks on Oracle Database Appliance Virtualized Platforms.
When you clone virtual machines with attached virtual disks, a clone of a virtual
machine contains the contents of virtual disks attached locally, but does not contain
contents of virtual disks attached in shared mode. If needed, you can clone the virtual
disks required by a cloned virtual machine in a separate step.
Use the command
oakcli clone vm
to create a virtual machine from a virtual
machine template. Use the
-repo name
option to provide the name of the shared
repository, where
name
is the name of the repository. Use the
-node number
option to
identify clause to identify the node on which you want to perform the cloning process,
where
number
is the number of the node.
