Take Your E-Business Suite to the Next Level – Part 2: Upgrading your E-Business Suite Environment On-Premise

Take Your E-Business Suite to the Next Level – Part 2: Upgrading your E-Business Suite Environment On-Premise

Authors: Simon Clarke, IaaS/DBA Practice Lead | JJ Millen, DBA Consultant, Namos Solutions

In this second part of our blog series, we will discuss the considerations for remaining on-premise and upgrading E-Business Suite.  Cloud offerings are becoming more and more prevalent, and it may seem futile to dispute the direction of the industry.  However, there are still good business driven justifications for staying On-Premise. 

The ‘Upgrading On-Premise’ Option 
The big question is “Why chose this option?”.

  • If you have new hardware with sufficient capacity, and you don’t yet wish to make the jump to cloud services.
  • You wish to retain complete ownership of your servers. 
  • As an organisation, you’re waiting to see market trends before making the decision. 
  • Your existing DR strategies are established and mature, so you don’t want to re-write the book. 

Regardless of the reason, the 12.1.3 end date is looming and beyond 31st December 2021, E-Business Suite Release 12.1.3 Premier Support will end leaving your business vulnerable and at risk. 

From conception to delivery Release 12.1.3 to 12.2 upgrade projects typically take around 9 months, so time really is running out.  Here is an overview of the most significant workloads for a 12.2 upgrade that you will need to factor in: 

  • Identification and redevelopment of customisations 
    The complexity of this workload is often vastly underestimated.  During this stage, it is very common to discover that a large proportion of customisations have been forgotten or left undocumented.  The redevelopment is largely due to the changes required to satisfy the new Online Patching functionality. 
  • The upgrade 
    There should be several non-production iterations of the upgrade, following rigorous testing procedures.  These iterations will require experienced E-Business Suite DBAs who should be familiar with new concepts such as Online Patching and Enterprise Command Centers (ECC).  The project iterations will require significant infrastructure, you need to ensure that you have the capacity to resource this. 
  • Testing 
    Your existing end-to-end testing, be it automated, scripted or documented will need to be updated and enhanced to reflect the new functionality in R12.2. 
  • Training 
    User training will also require some dedicated time to bring your users up-to-speed with the new interface and updated procedures.

Upgrade Benefits 

Long Term Support for 12.2.X 
Once you upgrade to 12.2, you will have the comfort of knowing that with only minor release updates your E-Business Suite will remain supported until at least 2031. 

Continuous Innovation 
As well as long term support, R12.2 also shifts to Oracle’s new “continuous innovation” model.  This means that new functionality is regularly delivered and due to the separation of the EBS technology stack from EBS applications code updates, you can quickly deploy new versions of the EBS tech stack without the additional obligation of upgrading the EBS applications code. 

Online Patching 
One of the most welcome new features of R12.2 is the introduction of Online patching.  Dual Filesystems reduce the downtime windows required when a patch is to be applied to your production instance. 

Visual Improvements 
The front end has been modernised to bring the look and feel in alignment with what is currently available in the cloud applications. Furthermore, it’s been enhanced for use on tablets and mobile devices, with a fingertip friendly interface using touches and swipes. 

Enterprise Command Centers (ECC) 
The ECC was released back in October 2018 along with R12.2.8, however it is compatible with R12.2.4 onwards. The latest version is currently V5. What it brings to the E-Business Suite is a holistic view of the data in a modern and interactive user interface. It provides a tool to uncover business insights, and data drill downs to pin point relevant action. The ECC eliminates the heavy reliance on custom operational reporting and enables users to intuitively analyse data so they can make confident data driven decisions.

Whilst there is no easy answer to the “Stay On-Prem or migrate to Cloud” conundrum, we have seen there can be good business and cost driven reasons to stay on-premise.  Finding the right option is a balance of business needs, short and long-term costs and weighing up the value of new Cloud based features.  If staying on-prem is right for your business, there are lots of benefits from upgrading to R12.2.
