Upgrade Process | Step-by-Step – Preparation

1. Understand the upgrade process

Understand upgrade concepts

Understand the Basic 12c Upgrade Tasks

Understand the SOA Cluster Upgrade Topology

Understand the Oracle Service Bus Upgrade to 12c

Understand an Upgrade to Business Activity Monitoring in 12c

Understand SOA Domain Upgrade Restrictions

2. Define a To-Be Topology

Understand new and changed features of 12c (12.2.1)

Understand an Enterprise Deployment

Decide on components (e.g. SOA, OSB, BAM, etc.)

Shared Weblogic Domain (for OSB / SOA / BAM) vs. separate Weblogic Domains

Upgrade Process | Step-by-Step – Preparation (2)

3. Decide on an upgrade strategy that fits to your requirements

In-Place Upgrade

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

Suitable for long running instances which should resume after upgrade

Side-by-Side Upgrade

New installation of schemas and domains

New deployment & configuration of the existing 11g projects

Suitable in stateless & short-running scenarios

Appropriate if the targeted sytem architecture should be diferent than with 11g or if the current topology is not

supported

Upgrade Process | Step-by-Step - Code Upgrade

10. Verify your results (Test) Testing before and after the upgrade is the key to success!

Define and document all testcases in advance

Make sure that you have a complete test approach in place bevore you start your upgrade

Esablish a test approach that covers all relevant test layers (Elementary Unit Tests, Component Tests, End-to-End Tests)

We decided to build our own OC testing framework based on JUnit Standard and SOA Suite APIs to integrate it within other implementations and to establish a proper test-driven development

This allows us to

use the same test approach for BPEL, BPMN, OSB, Java, Human Tasks, XSLT and XQuery…

re-route external references to a mock service implemented in the same framework (in Java) including changing references to standard web services so that database or file adapters can also be mocked

Human task handling (finishing the human task with a predefined outcome and predefined values)

Smooth integration into continuous integration environment

Straight Forward

Code upgrade with standard composites (using

BPEL, Database and File adapters) Testcases

successfully completed without any manual rework

Database Adapter for stored procedure calls

performed well after upgrade

Successfully transferred config changes like JTA

Transaction Timeout, Transaction Timeout of Beans

and SyncMaxWaitTime

Enabling of new Auto Purge function to avoid

Database growth

Deployment via Maven

What we‘ve learned…

Prepare for more complexity

Upgrading from Oracle BAM 11g to BAM 12c cannot be

handled with the standard upgrade procedures

OWSM / JDeveloper and Custom Policies because of

deprecated functions

HA Infrastructure setup took longer than our code

upgrade

Namespaces / Prefixes of some ext. XPath functions

have changed (solved via search & replace)

Challenges while upgrading large composites fixed in

Doc ID 2021736.1

Version 12.2.1 runs under JDK8 which can result in

additional work

Best Practices

High test coverage: define testcases well in advance and compare results before and after the

upgrade

Use a test framework that allows efficient (re-)execution of testcases for OSB and SOA -

including Mocks, Component and End-to-End Tests (e.g. OC Testframework)

Testing and pre-upgrade steps are the key points of success

Documentation about changed configuration parameters is important (document before

upgrade)

Plan the Infrastructure upgrade well in advance

Install BAM on a separate WLS domain to decouple runtime and monitoring components from

patching cycles (reduce downtimes)

Consider BAM Best Practices from the beginning
