12.1.3 to 12.2.5 EBS migration

Hello

We are in the process for the migration of our real EBS EBS environment 12.1.3 running on Red Hat Linux 5.5 with the version of the database 11.2.0.2.

We want to spend at the EBS 12.2.5 on Oracle Linux 7 with database 12.1.0.2.

I was thinking maybe to migration in 3 main steps that can be done at a different time to reduce downtime and the complexity of the migration time:

1 - migrate the database to 12.1.0.2

2 - migrate EBS to 12.2.5

3 - migrate the OS of the Oracle Linux 7

Anyone has any experience with this kind of migration or issues/recommendations. Is it better to do it in a different order or maybe make everytinhg at the same time?

Any help appreciated.

Kind regards

Hello

Agree with your sequence of steps to complete the upgrade to 12.2, the db should be a minimum of 11.2.0.4 @.

I advise you to see below the docs, that should help you and have a better understanding:

Interoperability note Oracle EBS Version 12.0 and 12.1 with Oracle Database version 1 (12.1.0.1) 12 c (Doc ID 1930134.1)

So, you might start with the upgrade of db as step 1.

12.2 - install & upgrade

Useful documents to 12.2 (Doc ID 1585889.1)

Oracle E - Business Suite Release 12.2: technical planning, road and Go-Live Checklist Note 1585857.1 (very useful doc)

Oracle E-Business Suite installation and upgrade version 12 (12.2) Notes for Linux x 86-64 Note 1330701.1

Also, feel free to mark my answers as useful or correct answer for others to know that the problem is solved.

  • EBS migration

    Hello world

    Please, I have a question, I do a migration of EBS 11.5.10 in RH4 Linux to AIX, so one of the steps is:

  • ASIC can run on the same server/db like EBS (R12.1)

    Hello

    We have an EBS (R12.1) environment and intend to use the CPSA. I've seen environments where the CAWC runs in its own environment/database, etc. and connects to an instance of the EBS. Which is the only type of available configuration or can CAWC run fully within an environment of EBS/instance on the same server? If so, what are the consequences of such a configuration, for example on the performance.

    Thank you

    NAT.

    Hi Nat,

    ASIC can be configured in two ways:

    1 centralized - where the EBS and VCP reside on the same application server.

    2 decentralized - where the EBS and CRS are on two different application servers.

    Basically the motor nucleus of CPSA of planning does all the planning in the memory of the application server (and not in the database). This planning process is highly require a lot of resources (memory) and requires a huge memory (according to the data, the type of plan and many other factors). If the application servers are not the right size, this led to the poor performance of the application. And if both the planning and EBS reside on the same server, there are possibilities that you slow the global treatment through the functions of the company. That's why decentralized architecture is preferred, where the planning process running on another remote computer of your EBS and it didn't there in not affecting transactional modules.

    Beyond that, you have the ease of maintenance in terms of correction, update, addition of multiple of VCP modules, if you're on a decentralised architecture.

    Centralized architecture is also not rare. Many companies run their planning and EBS on a single machine.

    I hope that the above gives you a point of view, using which you can choose what suits your business best!

  • Authentication UNIQUE difficulty for Chrome / EBS (Finance/forms)

    We experienced the same - but I don't think it's the cookies or Java that updated. It appears the Chrome Extension for Oracle EBS updated and the old cached version 1.1 files are not compatible with the 1.2. That's why I think that the "clear cache" fixed it

    Scalability, performance and functionality of discoverer have serious limitations.

    OBIEE is much better than discoverer in all directions.
