This document discusses migrating Java EE and ADF applications to Oracle's Public Cloud. It describes how the cloud can help decrease IT complexity and increase time to value for customers. It then demonstrates deploying sample Java EE and ADF applications to the Oracle Public Cloud using NetBeans and JDeveloper respectively. The document also covers whitelisting and limitations of the cloud as well as best practices for configuring applications in the cloud.

Cloud services significantly reduce if
not completely eliminate time to value
concerns as implementation time can
be as fast as immediate.
Faster time to value

Oracle Public Cloud
 Java & Database as a service
 Intended as a platform where
customer deploys an ISV’s solution
 ISVs need little to no code change

9. Copyright © 2012, Oracle and/or its affiliates. All rights reserved.9
Opportunity for partners:
Cloud Referral Program
 Available to any OPN membeber
 10% of the revenue
 Valid for annual or multi-year
subscriptions
 A good option for ISVs where
customer needs fast time to market
but has / wants no in-house platform

Exploring the sample Application

22. Copyright © 2012, Oracle and/or its affiliates. All rights reserved.22
Exploring the sample Application
1. Form based login
2. Users stored in the database + ReadOnlySQLAuthenticator
3. Group membership stored in DB
4. Authorisation is configured using entitlements
5. Application uses employee ID internally, which is read from the DB at
AM initialisation
6. Image servlet opens a direct connection to the DB to fetch images

Configuring BC
 The DB connection pool can be tuned in the IDE itself at development
time. We recommend the following settings in the JDev/ADF
"bc4j.xcfg" file:
– jbo.ampool.doampooling=true
– jbo.doconnectionpooling=true
– jbo.txn.disconnect_level=1
 These settings will maximize the usage of the WLS connection pool, instead of
maximizing the number of DB connections, which is the default tuning of the ADF/JBO
Application Module Pooling. These settings have been tested on the Java Cloud Service
and found to be appropriate.
