UPGRADING TO SOA 12.1 & 12.2Practical Steps and Project Experiences

Bruno Neves AlveseProseed UKJune - 2015

2


INTRODUCTION

• Provide insight in the migration and upgrade possibilities for SOA from 11g to 12c (if you still have SOA 10g we can discuss later )

• Provide arguments to decide what is the best way for your organization to upgrade to 12c given your starting point

• Discuss migration strategies

• NOT: complete step-by-step tutorial for all upgrade and migration paths

• NOT: upgrade for other Oracle products

WHAT’S NEW IN 12C R2?


WHY ELSE UPGRADE?

• New version of Java (12.1.3 = JDK 7, 12.2.1 = JDK 8)

– New features for developers

– Security enhancements

• Support Dates (see next slide)

• Often get best support on latest version

– E.g. don’t have to request back-ports for fixes etc

12


MAYBE NOT TOO MUCH RUSH

13


12.1.3 OR 12.2.1 ?

• You may prefer more bundle patches of 12.1.3 (none yet for 12.2)

• Need for new 12.2 features (e.g. IWS Reports, Insight)

• We prefer to go for the latest usually but YMMV

14


UPGRADE STRATEGIES

15

To reach your goals


REVOLUTION VERSUS EVOLUTION

10g to 11g: Lots of new features, but also disruptive change

• New architecture by introducing SCA standard

• WebLogic Server instead of OC4J

• Service Bus instead of OESB

• SOA and BPM both new products

11g to 12cR1 to 12cR2: Evolution instead of revolution

• Same architecture (SCA), same container

• Evolution of existing products

16

“a bit painful”

Much easier than a 10g upgrade!


UPGRADE STRATEGIES

SOA / BPM 11g to 12c

• In-place upgrade

or

• New env & Redeployment Key questions:

Long running transactions?

Can they be ‘drained down’?

Parallel Run or Big Bang?


SOA AND BPM SUITE 11G TO 12C

Runtime

• In place domain upgrade and reconfiguration

• No need to redeploy composites after upgrade

• Long running instances resume after upgrade

Design time

• Open 11g projects in JDeveloper 12c

• Import/export Service Bus projects from Eclipse to JDeveloper 12c

In-placeUpgrade

Side-by-Side


SOA AND BPM 11G TO 12C | PREREQUISITES

• SOA/BPM Suite 11.1.1.6 (PS5) or 11.1.1.7 (PS6)

• 64 bit JVM

• OPSS to use DB or LDAP based policy store

• Infrastructure Database must be supported Oracle 11g or 12c Database

• 11g and 12c Oracle Homes located on same host but different directories

• OWSM Policy Manager for Service Bus upgrade

19


SOA AND BPM 11G TO 12C | UNSUPPORTED

• Domain integrated with non-12c products

–Registry (OSR)

–Repository (OER)

–WebCenter including SOA/BPM task UI exposed as Portlets

• Developer deployments

–Admin Server only Domain

–XE database

• SOA/BPM not running on WebLogic Server

• In-place upgrade of BAM

Oracle Confidential –Internal/Restricted/Highly

20


RUNTIME UPGRADE STEPS

21

11g to 12c (1 of 3)

Read upgrade documentation and create upgrade plan

Create full backup

Create test set (recommended)

Purge instances – partly or totally (if possible)

Shut down environment

Update JDK to 64 bit JVM (if needed)

In-placeUpgrade



22

11g to 12c (2 of 3)

Update SOA Suite to 11.1.1.7 (if needed)

Migrate OPSS from file-based to DB-based (if needed)

Update SOA Infra Database to supported version (if needed)

Install WebLogic Server 12c

Install SOA Suite 12c and other components such as OHS and OSB

Execute RCU 12c to create 12c schemas

In-placeUpgrade



23

11g to 12c (3 of 3)

Execute Upgrade Assistant to upgrade 11g Database Schemas

Reconfigure Domain using Reconfiguration Wizard

Execute Upgrade Assistant to upgrade SOA Suite 11g

Check start and environment scripts

Start up environment

Run the test set to verify

In-placeUpgrade


ADDITIONAL EXTRA CONSIDERATIONS

• You can upgrade Complete Instances for post upgrade

– Scheduled Upgrade

• Service Bus

–Export project before performing the upgrade

• delete the OSB Metadata at 11g

–Migration from eclipse to jDeveloper (import/export)

LESSONS LEARNTfrom customer cases

LOTS OF SOA 12C UPGRADE EXAMPLES

• Large Dutch bank

• Dutch gas utility

• UK water utility

• Public Transport company

• Healthcare provider

• Vehicle leasing company

• Large City local government

27


LESSONS LEARNT (1)

• Be very careful of pre-reqs

• BAM is a non-starter (& can't do an in place upgrade if installed in the 11g domain)

• Design of long running processes is very important

– e.g. if you have some intermediate JMS queues that can give more options

• If possible don’t use an in-place upgrade

– More to go wrong

– Rollback is more difficult

• Carefully weigh risks of in-place vs extra effort (& maybe licence cost) of side-by-side

– Most cases favour side-by-side in our experience

• Tuning between 11g & 12c is very different - much easier in 12 (primarily SOA_INFRA connection pool sizing)

30


LESSONS LEARNT (2)

• Test strategy very important

• Training: e.g. consoles have changed, auto purge, error hospital, new features like that thingy that needs ESS (fault notification hospital), flow ID

• WLST diff in 12.2 - e.g. deployment scripts => don't focus on design time alone, make sure look at runtime

• Deployment if using Maven has changed a lot

• Leverage automation scripts to re-create wls configurations (DS, JMS, etc) on side-by-side

• Eclipse->JDev for OSB - DVMs in OSB, templates (do new analysis) - reason to do side-by-side (might as well improve prov).

• Assume you will have to open projects in 12c & redeploy (also cleaner)

• Don't wait! probably go to 12.2 but depends on testing31


SUMMARY

32


SUMMARY

• Going from SOA and BPM 11g to 12c is upgrade instead of migration

• Consider going straight from 11g to 12cR2

• Carefully consider your upgrade approach

• As ever careful testing is very important – especially if doing in-place upgrade

• Training to use 12c enhancements

• Don’t put it off – benefit from the new features you’ve already paid for
