R12.1.3 Upgrade Paths

ATG - Best Practices

Identification of required patches

Prepare a complete list of pre and post patches and recommended code

levels

Keep the system current on AD/ATG/OAM code e.g. latest AD/ATG RUPs on

11i/R12.0 and once on R12.1

High priority patches and Consolidated Patches.

Review “Known-issues” sections from Life cycle Advisor

Upgrade Best Practices

Patch merging and sequencing

Merge patches

Merge NLS patches per language. Apply NLS patches as “hot” patches

Perform uptime maintenance when possible e.g. hot patching of iHelp or

NLS patches, upload patch history

HRGLOBAL step before NLS ( Document 145837.1 & 414434.1 )

Stage patches locally accessible by mid-tier machines instead of on nfs

mounted or remote servers

Adpatch options and other reporting tools

Use applicable adpatch options to reduce downtime and track key upgrade

aspects using in-built tools

Use non-interactive patching

Use adpatch options such as nogenform, nogenrep, nocompile jsp,

noautoconfig, novalidate (1078973.1)

Use optimal values for batch size and #workers

Use OAM reports and Patch Wizard functionality to track patch timing, files

applied, functionality patched, impacted customized files etc. (976188.1)

Downtime reduction procedures

Use “Shared APPL_TOP” with “Distributed AD”

No need to apply the same patch on multiple tiers

Distributed AD adds to the degree of parallelism by distributing AD workers across

application tier nodes and improves D/G portion of the patch driver.

Use “Staged APPL_TOP”

Saves time to patch the file system (C/G portion) by using a patched up copy of

production instance file system

Use in 11i => R12.1 upgrade to avoid applying NLS C/G portion

Can use for R12.0.X => R12.1 upgrade and once on R12.1

For the duration of the upgrade, consider…

Disabling custom triggers and business events

Disabling auditing if enabled

If possible run in noarchivelog mode

Disabling flashback DB

Removing TDE from volume tables

Pre-upgrade activities

Identify and execute tasks that could be completed in a separate downtime

period, prior to the production upgrade

Use applicable steps mentioned in the "Downtime reduction" and “Upgrade By

Request” appendices E and G of the R12.1 upgrade guide

Upgrade RDBMS version to latest certified for the current APPS level ( 11.2.0.3 /

11.1.0.7 / 10.2.0.5 )

Convert to Oracle Applications Tablespace Model (OATM)

Compacts data, optimizes storage settings and I/O

Other planned HW or OS upgrades

Pre-upgrade activities ..

Use TUMS (“The Upgrade Manual Script”) to avoid running tasks that are not

relevant for your system

Convert to multiple organization architecture (Document 210193.1)

Drop MRC schema ( 11.5.10 and above )

Assign post upgrade jobs to specialized CM queue (by request_type, see

Document 399362.1)

Flush all the interfaces, such as Autoinvoice, Journal entry import, order import

Review and disable all debug, logging at site, responsibility, user level

Gather stats with GATHER_AUTO option for all schemas close to the start of

downtime

Pre-upgrade activities ..

Pre-create new large indexes created by upgrade (constrained to indexes on

existing columns)

Minimize historical data to be upgraded as per business requirements – “Upgrade

By Request”

Purge old and/or transient data before upgrading

Key recommended fixes

Affecting Upgrade Performance

AD-Parallel improved scalability: 8917381 (Part of 9179588 AD CUP)

Forms/reports generation regression with 11g: 8557019

General

Review document 244040.1 for latest EBS recommended performance fixes

Database tier configuration

Maximize SGA and PGA sizing

An upgrade only involves 10's of concurrent sessions

log buffer = 30 to 100 Mb

shared pool = 1 to 4 Gb

pga target = 3 to 20 Gb

buffer cache = multi Gb,

Note :- Be generous without causing excessive paging or swapping

– Set job_queue_processes = # of CPUS

– Set parallel_max_servers = 2 X CPUs

Database tier configuration …

Batch size and #workers

Batch size

10K is suitable for most installs, you can test other values from 1K up to 100K if time

allows

# Workers

Rule-of-thumb is between 1 and 1.5 x #CPUs

Monitor Below during test upgrade.

Memory utilization (no swapping/ excessive paging)

CPU utilization (scale down if at 100%)

I/O response times (scale down if averages > 20 ms)

Runtime Performance Testing Tips...

Use Automated, scripted tools

EBS Test Started Kits (Winrunner/QTP)

Bundled QA based automated scripts for EBS testing - Patch 8408886

Oracle Applications Testing Suite (Accelerators for EBS)

Web and Forms based flows

Complement with user participation tests and batch load tests with frequent and critical
