Due to poor marketing on our side, Oracle is able to do the app tier, too.
We promote it for EBS customers the most.
Now, Delphix is where you want to go if you want to do non-Oracle, too
You know Uncle Larry isn't going there with our cloning... :)

What I find of particular interest is the notion (from what I’ve read,
this seems possible) of packaging a database and the associated web/app
components together.
For example, if I want to restore a database backup from a year ago, it’s
incredibly useful to also be able to restore the associated application
version at the same time.
To have one tool that manages this would be very nice and it sounds like
Delphix would be able to support these kinds of associations.
Add to that the need to manage external resources such as external file
shares (ie: the files pointed to by your bfiles or perhaps the XML in your
database) and keep them all synchronized to specific points in time that I
could restore too, would make for a very powerful tool for companies who
routinely have to look at “how things were” at some point in the past, for
whatever reason.
Being able to flash a database back in time is great… but all too often
the entire application layer needs to go with it, along with other stores.

*Subject:* Re: Clone tool
To get closer to a useful answer, how about if instead we just discuss a
specific scenario? Let's start with a scenario similar to that the
original poster had posed?
Let's say someone has a 10 TB production database from which they want to
create 10 non-production databases for development, testing, training, etc.
Here's the first question: how much storage must be provisioned to the
non-production target server(s) to accommodate the 10 new databases?
Here are some answers that I can provide confidently...
1. Using RMAN DUPLICATE TARGET DATABASE, they need 100 TB for the
target server(s)
2. Using Delphix, they need 10 TB for the Delphix appliance and 0 TB
for the target server(s), totaling 10 TB
I'm not certain how much storage would be needed using solutions from
CommVault, NetBackup, TSM, Actifio, Oracle Snapclone, Oracle12c PDB clone,
Exadata, and other solutions, because I am not as familiar with them, so
I'm hoping others will fill in?

Hi Andrew,
Cloning is done by storage snapshots. I reacted because Commvault can do
cloning and does it for supported storage for a long time. Data masking is
something that Commvault doesn't do, that is true.
In the modern world, the notion of what exactly is backup is blurred. I
must say that Oracle has been very slow with adopting snapshots for backup
purposes. IBM, for instance, has ACS (advanced copy services) which does
support taking snapshots. RMAN doesn't support storage snapshots. So,
"traditional" backup solutions like Commvault, NetBackup and TSM are all
doing the same thing as Delphix and ActifIO, when it comes to using storage
snapshots to clone a DB. Of course, as is the case with many modern trends
in the IT, there is a flood of buzzwords: "virtualization", "data as a
service" (my particular favorite) , "infrastructure as a service",
"software as a service" and many more.
Delphix positions itself as a new way of doing backup and has somewhat
privileged position on this list. It is heavily promoted by what I consider
a pure and unadulterated marketing. I didn't react until there was too much
of "Delphix is web-scale" message for my taste on this group.
