Oracle Tips by Burleson Consulting
EnterpriseDB license breaks down into 3 licenses that define the
level of support you receive from EnterpriseDB. I want to make the
point here that while I will try to make this as accurate as I can,
I am not a lawyer or an employee of EnterpriseDB. The licenses can
change between the time I write this and the time it's published or
anytime there after. You can go to EnterpriseDB.com and subscribe
(after reading the information carefully) or to get the exact
details, call an EnterpriseDB sales person.
off, both Oracle and EnterpriseDB provide free servers for
development and testing. That means you can download it and create
non-production applications and test them to verify they work. If
you use them for production purposes (over certain limitations that
I speak to below), you need to buy a license.
EnterpriseDB provides a free, limited use license for low volume
production. Oracle also provides a scaled down version called
Oracle 10g Express Edition. These two editions have similar
limitations. The EnterpriseDB limits are: 6GB of disk space, 1GB
and 1 CPU. These free versions are free to develop, test and run in
production, provided you do not surpass the limits that have been
set. Once you need to scale up, you have to look at your
requirements and needs.
this level with both Oracle 10g XE and EnterpriseDB, your support
options are limited to the online forums. Oracle's support forums
are much more active at this time. However, EnterpriseDB is new so I
expect the volume to pick up over time. In general, response time
on both is superior.
provides additional licensing that is further tiered by the number
of CPUs and limitations on the feature set. As this is not a book
about Oracle, I will use the Oracle Enterprise Edition as the point
of comparison as that is the version that most closely matched the
the free, limited use edition, EnterpriseDB has chosen a model of
support per CPU. What that means is that the CPU has a set cost and
you get practically all the features of the database. There are no
feature tiers except for the optional Replication Server available
with the premium license. The cost per CPU is the same at 1 CPU as
it is at 10 CPUs.
current (Sep 2006) price at oraclestore.oracle.com has Oracle 10g
Enterprise Edition (EE) at $40,000 per CPU. According to the
example on the store page, if you have 4 computers, each with 1 CPU
and 1 computer with 8 CPUs, you would require a 1 + 1 + 1 + 1 + 8
(12) CPU license. That would work out to 12 * 40000 = 480,000. If
you are running multi-core CPUs, the calculation gets a little
tricky but to keep it as simple as possible, we can say that 12
Oracle EE licenses would cost us $480,000. Remember that number.
EnterpriseDB works the same but at a much lower price. EnterpriseDB
has two paid tiers of support. You can buy a Basic License for
$1500 per year or a Premium License for $5000 per year.
the same environment we discussed above (12 CPUs), the most
expensive license you can buy from EnterpriseDB is 5000 * 12 =
60000. Compare $480,000 to $60,000 and you can see where
EnterpriseDB particularly shines.
make fun of a popular public announcement commercial:
$480,000: This is your database on Oracle.
$60,000: This is your database on EnterpriseDB.
let’s take a moment and see what you get with each type of license:
basic license gets you access to updates and patches (kind of like
metalink support for the Oracle licensees), access to the forums and
knowledge base, and Web-based Support from Monday thru Friday,
Premium - $5000/Year
as basic but with 24x7 phone and Web-based support, product
performance tuning assistance, a designated contact person and
access to the EnterpriseDB source code. Premium also allows you to
obtain the Replication Server for an additional charge. In my
opinion, this is the sweet spot for larger organizations and people
just moving to EnterpriseDB for the first time.
the low-end of support (basic), you can run EnterpriseDB on your
hardware for 12 * 1500, or $18,000 per year. And if 1-day turn
around on production issues is acceptable (and it is for many
applications), basic is a perfect solution for you.
important thing to note is that you can decide what your support
needs are and plan for them. It's doubtful that your support needs
will change as your application grows but it's possible that you
will need to upgrade to bigger and better hardware over time.
you are considering what kind of license and what kind of support
you will eventually need, you can download the free version and
start developing your application.
