From 10g to 11g
Why it was not just an „upgrade“?
 Product foundation changed to
Weblogic Server
 Introduction of Service
Component Architecture (SCA)
 Oracle Service Bus & Mediator
instead of OESB

From 11g to 12c
Evolution instead of revolution
 No fundamental changes
in the underlying
platform
 Same architecture (SCA)
and same container
 Evolution of existing
products & components

SOA 10g to 12c
• 1) Migration to 11g and in-place upgrade to 12c, or
• 2) Redesign and migrate to 12c
SOA / BPM 11g to 12c
• 1) In-place upgrade, or
• 2) Migration

SOA / BPM 11g to 12c | Overview
• Defining an upgrade strategy
• Performing pre-upgrade tasks
• Installing 12c software
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 8
Pre-Upgrade
• Create / Upgrade Schemas
• Domain (Re-) Configuration
Upgrade
• Post-Upgrade Tasks
(such as reappling customizations, copying custom XPath
classes, reapplying EDNTopic, delete tmp-folders)
• Verify success
Post-Upgrade

2.1 Pre-Upgrade

10.
Defining an upgrade strategy
In-Place Upgrade Migration
 Schemas and domain directory
upgrades are performed "in
place" (updates existing 11g
files)
 Oracle Home binaries are
upgraded "out of place"
(binaries are installed in a new
directory)
 No need to redeploy
composites after upgrade
 Long running instances
resume after upgrade
 New installation of schemas
and domains
 New deployment &
configuration of the existing
11g projects
 Suitable in stateless & short-running
scenarios
 Adequate if the targeted sytem
architecture should be diferent
than with 11g or if the current
topology is not supported
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 10

11.
Performing pre-upgrade tasks (in general)
 Execute a complete backup of your 11g environment
 Apply recommended database parameters
 Save copies of customized start scripts, configuration files,
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 11
policies
 Is your database supported?
 Infrastructure Database must be a supported Oracle 11g or 12c Database
 Is your operating system supported?
 Upgrading from a 32-Bit to a 64-Bit Operating System
 Is your JVM supported?
 64 Bit JVM
 See Upgrade Planning Guide and Interoperability and
Compatibility Guide for pre-requisite details

12.
Pre-upgrade tasks for the in-place approach
 Do you regulary clean your
SOA Repository?
 Purge unused instance data
(upgrade will upgrade all open
instances)
 Can your version of SOA be
upgraded?
 Starting points are:
11.1.1.6 (PS5) or 11.1.1.7 (PS6)
 Is your topology supported?
 11g and 12c Oracle_Homes located on same host but in different directories
 Domain is not integrated with non-12c products (OSR, OER, WebCenter)
 OPSS to use DB or LDAP based policy store
 SOA/BPM is running on WebLogic Server
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 12

13.
Installing 12c software
 Install 12c FMW Infrastucture
Distributions
 Install 12c SOA Suite
 Install other components
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 13
as needed
 New and Deprecated Terminology
 MW_HOME (11g) => ORACLE_HOME (12c)
 PRODUCT_ORACLE_HOME => PRODUCT_DIR
 Oracle Fusion Middleware farm (used in 11g to
refer to a container for a WLS domain) => term is
eliminated in 12c

2.2 Upgrade

15.
In-Place Upgrade Steps
1. Create DB schemas for 12c
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 15
via RCU
2. Execute Upgrade Assistant
to upgrade 11g Database
Schemas
3. Reconfigure the 11g domain
using Reconfiguration Wizard
4. Execute the Upgrade Assistant to
upgrade SOA Suite 11g

16.
2.3 Post-Upgrade
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 16

17.
Post-Upgrade Steps
 Verify file permissions
 Re-apply customizations to scripts and configuration files
 setDomainEnv script (e.g. JVM memory settings, Truststore, etc.)
 config.xml
 Start Servers
 Admin Server
 Node Managers
 Managed Servers
 Other components…

3 Upgrade Results from Real-World Projects
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 18

19.
Components in use
 As part of the 10g to 11g migration all long-running processes
have been replaced with scheduled short-running processes
 All processes are implemented in BPEL 1.1 / BPEL 2.0 (no SB /
OER / BAM)
 Usage of: Component Properties, DB Adapter, XSLT, Calls to
external Web Services, Fault Management Framework, Business
Rules, DVMs, File Adapter, FTP Adapter, EDN
 Environment with one Admin Server and one Managed Server SOA
(configured as a cluster for scalability reasons)
 Approx. 100 SOA composites in production

20.
Upgrade Results - Runtime
 First testcases
with approx. 40
composites
completed
successfully
(without any
manual rework)
 Database Adapter
for stored
procedure calls
performed well

Upgrade Results - Runtime (2)
 EM shows list of
composites with
start-up issues
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 21
 Extended
deployment pre-validations
 e.g. wrong File
Adapter configuration
 Issues we
identified:
 Composites with EDN
 Embedded Java with
non-supported API
calls

22.
Design Time | Opening 11g project in JDev 12s
 Migration Assistent
starts to migrate the
project
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 22

23.
Design Time | Project Structure
 Project folder structure has
slightly changed
 *.componentType files have
been removed (content is
now part of composite.xml)
© OPITZ CONSULTING Upgrading SOA / BPM Suite from 11g to 12c GmbH 2014 Seite 23

24.
Design Time Recommendation
 Import MDS artifacts into Design Time MDS first, then open
the project
 Check library dependencies
 Check and modify settings in adf-config.xml (if needed)

Findings
 SOA Server started only in ADMIN mode
 Clean-up of the server-cache directory helped to solve the problem
 Solution was already documented under Doc ID: 1330224.1

didn’t expect a zero touch approach
 Pre-upgrade steps are the key point of success
 Documentation about changed config parameters as well as
a proper test concept is important
 Blogpost: Best Practices for SOA 11g to 12c Upgrade
