| oracle
tuning frequently asked questions |
|
Q:
What is your usual strategy for tuning a database and
its environment?
A: Our strategy will depend on your circumstances. However, we typically gather
a number of key performance measurements, both at system and database level.
These are used in conjunction with user and support staff testimony (where available
and appropriate) to identify the main high-level bottlenecks. We then drill down
using custom scripts and standard tools to identify the sources of these bottlenecks,
before devising solutions to eliminate them.
Q: A specific part of my application
is performing particularly badly. Can you fix it?
A: We will always concentrate first on tuning any functionality identified by
the client as causing most problems. In the vast majority of cases you will see
a marked performance improvement in those areas when we have finished.
Q: If you find inefficient code
in our applications, can you rewrite it?
A: If the code is stored within the database as PL/SQL, we can amend the code
on request (but you should check the support implications for 3rd party products).
We will not normally amend other code, but will document the inefficiencies
(and can provide details of how these pieces of code could be better rewritten)
so that you can report these to the vendor for amendment.
Q: Do you provide warranties for
any amendments done?
A: We provide two weeks of free remote support for any changes made.
Q: Which Oracle database versions can you tune?
A: We can tune all versions of Oracle.
Q: When can we expect documentation
for the tasks performed?

exercise. You are guaranteed to have a copy of the documentation within two
weeks
of work completion.
Q: We require an installation
to be tuned for our client. Do you offer resales/subcontracts?
A: Yes. We can rebadge our services, or can pay a one-off commission.
Q: Can you independently
verify a client's installation as fit for production?
A: Yes, this is one of our more commonly-requested services. Please
contact us for further details.
Q: How can we be sure of your credentials?
A: We have been tuning Oracle databases and environments for our clients since
1996, and company references are available on request.

| oracle
license frequently
asked questions |
|
Q: What is the difference between
Oracle Standard Edition and Oracle Standard Edition One?
A: There are two differences. Firstly, Oracle Standard Edition One can only
be licensed on servers that have a maximum capacity of 2 processors (CPUs). If
your server has a maximum capacity of 3 processors or more then you will have to purchase
Oracle Standard Edition (or if it has a maximum capacity of more than 4 processors, you will have to purchase Oracle Enterprise Edition). Secondly, Oracle Standard Edition One does not support
clustering whereas Oracle Standard Edition includes Oracle Real Application Clusters.
Q: I only use 2 processors on my server, but it can
support 4 processors. Do I still need to purchase Oracle Standard Edition rather
than Oracle Standard Edition One?
A: Yes. Your eligibility to use Oracle Standard Edition One is not determined
by how many processors in place or in use, but by how many processors the server
has capacity for.
Q: I would like to cluster my servers. Which license
level should I choose?
A: This depends on how many processors there are in your cluster. If you have 4 or
less then you can purchase either Oracle Standard Edition or Oracle Enterprise
Edition licenses. If you have 4 or more processors in total across the cluster then you must choose Oracle Enterprise Edition. Oracle RAC (Real Application Clusters)
is a licensing
option for Oracle Enterprise Edition.
Q: Are there any minimum order requirements when purchasing
Named User licenses?
A: Yes. The minimum order requirements vary depending on which database product
you select. These are:
Standard Edition One - 5 Named User Plus licenses per server
or the total number of actual users, whichever is greater.
Standard Edition - 5 Named User
Plus licenses per server or the total number of actual users, whichever
is greater.
Enterprise Edition - 25 Named
User Plus licenses per processor or the total number of actual
users, whichever is greater.
Personal and Lite Editions - 1
Named User Plus license or the total number of actual users,
whichever is greater.
Q: Do I need to buy Named User Plus
or per Processor licenses?
A: If you select the Named User Plus licensing option then you must license all
the users who are using the Oracle Database, as well as all non-human operated
devices accessing the Oracle Database. An example of a non-human device would
be a sensor that connects to a database. If a human-operated device such as a
bar code scanner connects to the database then all humans operating these devices
need to be licensed. If the Named User Plus population is likely to be very high,
it would
be more cost effective to license per processor. Where it is impossible to quantify the user population (such as in an Internet environment), then you must license per processor.
Q: My server contains multi-core processors. How do
I price this?
A: Until recently Oracle counted each physical core as a full processor and they
were licensed as thus. Under the new processor definition each core of a multi-core
chip is priced using a "licensing factor". These licensing factors are as follows:
Sun UltraSPARC T1 - 0.25
AMD/Intel - 0.5
All other multi-core processors - 0.75
Single core processors - 1
Therefore if you have two dual-core
AMD Opteron processors, the cost will be 0.5*4*list
price. Two four-core UltraSPARC T1 processors will cost 0.25*8*list price.
Q: Do multi-core processors affect the processor limits on Oracle Standard Edition and Oracle Standard Edition One?
A: Yes. Oracle Standard Edition can only be used on servers that have a maximum capacity of 4 single core processors (CPUs). For multi-core processors, the limit per server is determined by multiplying the "licensing factor" (shown in the previous answer) by the number of cores. The result must be less than or equal to 4, and the number of cores must be less than or equal to 8.
In a RAC environment, this limitation applies to the whole cluster (i.e. the result of multiplying the "licensing factor" by the total number of cores in the cluster must be less than or equal to 4, and the total number of cores in the cluster must be less than or equal to 8).
Oracle Standard Edition One can only be used on servers that have a maximum capacity of 2 single core processors. For multi-core processors, the limit per server is determined by multiplying the "licensing factor" (shown in the previous answer) by the number of cores. The result must be less than or equal to 2, and the number of cores must be less than or equal to 4.
Q: Can you offer me a discount on Oracle list prices?
A: Yes. Please contact us with your requirements and we will advise you on the
level of discount we can offer.
Q: Once I have placed my order how long will I have
to wait for my license details?
A: Your order is logged with Oracle who
then issue us with a license number for you. This process
can take up to 10 business days.
Q: What are your payment terms?
A: Payment is due within 30 days of the invoice date (subject to approval). For larger orders or maximum discounts, payment-on-order is required.
