Hi,
CRP's are conducted to ensure that understanding of people doing implementation is right and inline with user requirements. It also
looks to un-earth previously un-discussed process and business flow issues.

Oracle Instances: Vision Development Test Production
Let us discuss something on the instances which a consultant normally works on...
Instance is an address for a location where Applications database is stored.
We might have heard of many instances such as Vision, Test, Development,CRP I, CRP II, UAT, Production etc.... but apart from
the name there is no change in the behaviour of any of the Instances.
All instances carry the same technical features and functional setups, no difference what so ever in any of them, but why we call it
by different names then ?
The different instance names are given based on the purpose for which it is used. Every instance is created with the same features
and specifications, only naming is done based on the usage or the purpose.
We will see the standard or common purposes for which different instances are used in
an implementation.
Test Instance
It is a fresh instance which is used by the Implementation team to try out new setups and work arounds as per the clients business
specifications and arriving at final solutions. Apart from that test instance is used for testing the performance of installation as well as
other factors. The life of this instance starts from the first day of kick off and ends when the production begins or system has gone
live.
2. Development Instance
It is also a fresh instance when installed, but more or less it replicates the test or Production instance (normally cloned). The
purpose is to make constant development in the current business process and the system performance and working out new
methods in solving critical bottlenecks with the current system. The life of this instance is infinity, since there is no end to
development, it is an ongoing process, it continues even after the system has gone live.
Production Instance
It is a fresh instance installed with an intention to share it with all the users of the client with fine tunning. This instance is different
from Test and Development with respect to the number of users, size of the database, security features etc. The life of the
production instance begins when the User Acceptance testing is done, and it continues till the company is in existence.
Vision Instance
It is different from all other instances because the installation comes with the data, whereas all other instances are Fresh. Even
though there is no particular necessity to have this instance in an real time scenario, but it is better to have a vision instance always
for the following reasons:
1) It serves as a practice for the DBA to find out the installation problems that occurs due to hardware failures.
2) Functional consultant often try out a small business scenarios to find out solutions, in order to try out these scenarios, they
need to do all the mandatory setups in an instance then only they can perform it. If they had vision instance, they can use the
existing setups to try out thier business scenarios
3) Vision instance also acts as a tutor to the Functional Consultants in case they are lost in performing critical setups.

erp , environment
Hi,
I would like to know the difference between development insatance and test instance created after production instance.
I know development is used for development and test is used to test the development or customizations.
But how could i used both these servers for best patching practice?
How frequest these two server should be refreshed from prod?
what should be the patching strategy?
Kindly provide me with extra details and porpuse of these two extra instances.
and how can i use them upto optimum level (real time example please).
Thanks.

Registered: 04/18/08 There are many use cases and types of test instances. We are a large shop and have multiple test instances -
some test instances are for DBA use and some are for functional use.
DBAs have a patch test instance where a requested patch is first applied to verify that the patch application is
error free. The patch is then applied to the other test instances where functional testing takes place to verify
that the patch fixed the issue in question. Once verified, the patch is then applied on the pre-production,
production and dev instances.
The functional test instances are used by the functional team to test implementations of new
functionality/customizations/extensions. The DBAs also use them to verify the migration process of
customizations/extensions from dev to test instances is error-free.
We typically clone all of these test/dev instances frequently (once a month or once every two months, or as
required) from production

Registered: 03/13/06 Hi,
3. Patchset level should be always identical on all these instances. I believe the best practice would be patching
the test instance, verify that the patch fix the main issue(s) and no more issues come up by applying the
same patch, then apply it on your production instance. You can refresh the development instance by cloning
the test/prod instance then.
You may also review the following documents and see if it helps.

we have two extra servers other than production.
We are planning to use them as follows.
Dev:
- a copy of the prod atleast two months old.
- will be used for development/cutomizations/extention.
- patch testing.
- new setups
Quality:
- a latest copy(atmost one month old) of the prod.
- pre-production patching.
- DBAs to verify migration process from dev to quality.
Srini,
i understood the need for test,functional and devlopment in your environment.
But what is the need for pre-production.
You are applying patches on pre-production,production and development with out further
verification after each of this instance is applied with the patch?
kindly add some tasks which i could assign to specific server in my environment.
Thanks.

Registered: 04/18/08 Our pre-production instance is an exact copy of production - identical hardware and software, identical
architecture etc. It is used to troubleshoot/replicate any issues in production, so that the issues can be
diagnosed without affecting production. The pre-production instance is located in a different data center from
production and can be used as a production instance in case a disaster strikes the production data center.
Once patches have been tested thoroughly in the test instances, they are then applied in pre-production and
tested again. If no issues are found, then patches are applied to production and dev instances.
