Key Advantage – Online Patching

• Online Patching Support – Reduce downtime

• Take Advantage of New Features

• Source : Oracle

13

Database Edition based online Patching

• E-Business suite available during Patching

• Downtime Window predictable and in minutes

• Patches are applied while Application remain Online

14

Online Patching – Things to keep in mind

• Since R12.AD.C.Delta.5 “downtime” mode can be used. No online patching compatibility and is quicker

• R12.2 patches are not normally tested in downtime mode. It is only supported where explicitly documented or when directed by Oracle Support or Development (e.g. 12.2.4 or 12.2.5 RUP)

• Be aware that all custom code need to be registered in preparation for an upgrade to R12.2, so that it is compliant with Online Patching standards

• This must be done prior to upgrading to R12.2 upgrade. The Online Patching Readiness Report, Manual Fix Readiness Report, Global Standards Compliance Checker script and Online Patching Database Compliance Checker can be used to support this process

15

Managing customizations

• Objects which need to be Editioned

• Custom and Third party schemas

• Enabling Editioning for EBS users

• Applying customizations

• Defining customizations with Custom

Synchronization Driver File

• Refer to Oracle Note : 1577661.1, "Developing and

Deploying Customizations in Oracle E-Business

Suite Release 12.2."

16

Questions to ask?

• Is your EBS out of support?

• Are you out of compliance for Hardware?

• Are you planning an upgrade to latest OS?

• Does your Database need to be upgraded?

• Does your infrastructure need Platform Migration?

• Are you planning to move to Virtualization?

• Are you planning an upgrade to Storage?

• If your answer is Yes to any of above questions then

you are thinking in right direction for R12.2 upgrade

17

Questions to ask?

• Does your business require New functionality?

• Is your organization planning to implement advanced Security Options?

• Is Downtime and High Availability becoming more critical for your business?

• Are your users demanding Mobile access and Tablet compatibility?

• Are you looking for Cloud based solutions?

• Are you planning Minor upgrade to Environment?

• If your answer is Yes to any of above questions then you are qualified for R12.2 upgrade

Optimizing R12.2 Upgrade

19

R12.2.5 Upgrade Phases

• High Level Overview of R12.2 Upgrade Process


20

Optimizing R12.2 Upgrade - Preparations

• Create Repeatable & Reliable Process

• This is key to a successful upgrade

• Define Scope

• Review Certification

• Project Plans

• Execution Plan

• Adopt best Practices

• Utilize Upgrade Advisors

• Repeatable Process

• Stick to the Plan

21

Optimizing R12.2 Upgrade - Preparations

• Ensure Hardware and Software Stack is fully certified for R12.2 E-Business suite version

• Review Database and E-Business Suite Certification at Oracle My Support certification Tab

• Check E-Business Suite R12.2 Interoperability Notes to ensure all Products are certified to run with R12.2

• Check Hardware and Virtualization Certification to ensure you are deploying supported Architecture

• Verify and confirm Licensing obligation with your Oracle Rep – VIMP otherwise you will be charged for any product which was enabled during upgrade process

• Check certification of all Third Party Products with R12.2. Ex: In Oct 2014, R12.2 was not certified with KoFax, Markview. We had to work with KoFax development team to develop upgrade Path for KoFax and give us latest certified version compatible with R12.2

22

R12.2 Readiness Report

• Report is key for starting R12.2 upgrade

• Online patching Readiness Report (MOS Doc ID

#1531121.1)

• Online patching Analysis Report (Patch #16236081)

• Available for all releases prior to 12.2

• Reports all violations of “Non-Editioned Objects

can’t reference Editioned Objects”

• Some EBR violations are automatically fixed by the

12.2 upgrade

• The report is key to determine the scope of effort on

custom code

23

Infrastructure Layer Tuning

• Scale up CPUs and Memory – As per Licensing

• Bump up Virtualization resources

• Move Database to high performance storage. Ex: ASM

• If Database is on NFS, implement Oracle dNFS as it would increase the upgrade speed by 3.5x. Utilize explicit NFS settings recommended by Oracle

• Implement “huge pages” to offload your CPUs

• Avoid running upgrades on RAC nodes as you may end up In locking situations or performance issues due to interconnect and parallel threads at application end (parallel adworkers)

• Rather shift CPUs from secondary RAC node or UAT to Production Database Tier

24

Infrastructure Layer Tuning

• Often overlooked – Vital for Performance

25

Turbocharge R12.2 Upgrade with

Hardware Migration

• Killing 2 birds in 2 stone

• Setup Standby

• Enable Flashback

• Enable DR site

• Perform Smoke test

• Preserve Standby and App File system – No

change allowed

• Perform R12.2 upgrade during Go-Live on new

Hardware

• This reduces Risk and maximizes Recovery options

26

Database Layer Tuning

• Tune Database for optimal upgrade Performance

• Perform major Database upgrade as Phase 1

• Database Preparation Guidelines for an Oracle E-

Business Suite Release 12.2 Upgrade (Document

1349240.1)

• Ensure that the large tables populated or modified

by the release 12.2 upgrade have a large extent

size (1-10MB). Small extents will seriously limit the

AD Parallel batch size used. They will also increase

the occurrence of high water mark waits

• Disable Auditing

• No Archive Log Mode

• Disable Flashback

• Disable Recycle Bin

29


• Drop Custom Indexes, Triggers

• Drop Custom Materialized Views

• Truncate Mlogs – This can significantly reduce

downtime

• Gather Schema Stats

• Gather Fixed Object and Dictionary Statistics

• SQL Monitor Report / Patch Timing Report

• Disable or drop any DBMS Scheduler, DBMS Jobs

& Autotask activities during the Upgrade

• Disable unwanted custom VPD policies

• Disable TDE from high volume Tables

30

Optimizing R12.2 – Application Layer

• Global Standard Compliance Checker and

Readiness Report

• Purge all Data that is no longer needed

• Purge Attachments (LOBs)

• Purge Workflow

• Flush all the interfaces, such as Auto Invoice,

Journal Entry Import, Order Import etc.

• Drop MRC Schema if it still exists (Upgrade from 11i

only)

• Take care of all CEMLI & Customizations

• Migrate SLA Data

31


• Purge & Archive unwanted Data

• Source : Oracle

32


• Convert to the new Multiple Organizations (Multi-

Org) architecture (Upgrade from 11i only)

• Utilize Parallel AD & Parallel Autoconfig to speed up

Pre & Post Upgrade Steps

• Gather the schema statistics (with GATHER_AUTO

option for all schemas) close to the start of the

downtime. Use FND_STATS or Gather Statistics

concurrent programs

• Perform Dry Run before Go-Live

• Freeze any Code Migrations before Dry Run

33


• Apply latest available Online Patching Enablement

Patches

• Applying the Latest AD and TXK Release Update Packs

to Oracle E-Business Release 12.2 (Doc 1617461.1)

• Oracle E-Business Suite Release 12.2: Consolidated List

of Patches and Technology Bug Fixes (Doc 1594274.1)

• Include & apply latest available Module Patches

• Include & apply latest available CPU & Security Patches

• And of Course apply latest Oracle E-Business Suite

12.2.5 Release Update Pack (Patch 19676458)

• And Oracle E-Business Suite Online Help for 12.2.5

Release Update Pack (Patch 19676460)

34


• Use The Upgrade Manual Script(TUMS) to avoid running tasks that are not relevant to R12.2 (Upgrade from 11i Only)

• Consider running Paralle AutoConfig and Distributed AD on a multi-node system

• Minimize Historical Data To Be Upgraded (Upgrade by Request) (Upgrade from 11i Only)

• Parallelize pre and post upgrade technical activities

• Define separate concurrent manager queue for post upgrade jobs. If using RAC then “Parallel Concurrent Processing (PCP)” could be used for post-upgrade concurrent jobs

• Review Resource Manager to ensure that upgrade sessions have access to all resources

35

Tech Stack considerations

• Perform R12.2 upgrade by utilizing single file

system. It is NOT recommended to add nodes to

12.2 Rapid Install upgrade file system until AFTER

the upgrade to the latest 12.2.x RUP is complete.

• Thus previous advice of using Distributed AD and

Shared APPL_TOP is not applicable. Though this

can be utilized for Post upgrade Steps.

• ‘‘Defer Upload of Patch Information’‘ option cannot

be used, as subsequent patches may rely on

information from previous patches. The Release

12.2 upgrade is a series of patches.

• Use maximum of 1 x # of CPU for AD workers

• Use 1 x # of CPU Job queue processes

36

Big Bang vs Phased Approach

• Phased Approach

Perform any RDBMS Upgrade, Platform Migration,

Conversion to OATM prior to R12.2 upgrade window, into

a separate downtime period

• Big Bang Approach

Plan and perform OATM, Database upgrades and

Platform Migration prior to R12.2 upgrade

• Both the approaches have it’s own Pros & Cons.

• Downtime requirement by business will dictate

which approach to chose from. Carefully evaluate

the pros and cons and chose an approach.

37

Testing Upgrade Process

• Performance test the entire upgrade process on a system that is identical or comparable to the production system with same Architecture (Similar CPU, IO, Memory and data volumes/ages)

• Recommendation is to procure Production Hardware ahead of time and perform multiple iteration on Production Hardware including Dry Runs to have predictable timeline and process. This eliminates any surprises during Production Go-Live

• Start performance testing immediately after First Upgrade Iteration or as early as possible

• Allow time for multiple iterations of performance testing so that performance issues can be resolved and upgrade timing is reduced to desired results

• Tune all Long running SQLs

38

Testing Upgrade Process

• Apply “Break your New Shoes” theory !

• It’s Painful, avoid these costly mistakes

39

Plan your Upgrade

• Most Important – Planning, Planning & Planning

• “By failing to prepare, you are preparing to fail” - Benjamin Franklin

40

Plan your Upgrade

• Sample Timeline using OUM Methodology

41

Plan your Upgrade

• Well defined Sample Resource Plan

42

Plan your Upgrade

• Resource Planning

• Assign separate Resources for Implementation vs

Day to Day support

• Often mistake is been made to assign

implementation DBAs to the project ignoring the

need for Day to Day support

• This often results in implementation team running

out of cycles for providing day to day Support

• Assign dedicated Implementation vs Support team

to the project

43

Plan your Upgrade

• Keep enough buffer for Go-Live window to account

for delays and give breathing room to team

• Have your Coffee or Tea. Your preference!

• Take Rest & Relax. Don’t stress!

• Above all, stick to the Plan. Do not deviate. This is

where blunders are made. Every time I see an urge

to make change during Go-Live you will run into

issues. Production Go-Live has to be exactly the

replicate of UAT and Dry Runs. I cannot stress this

enough. Regardless of business pressure, stick to

the plan.

• Enjoy your successful Upgrade !!!
