Themes Upgrade Libraries Backwards Compatibility Improvements New and improved Tools Simplify build process and Improve build promotion orchestration

Themes Upgrade Libraries Backwards Compatibility Improvements New and improved Tools Simplify build process and Improve build promotion orchestration

Library Upgrades JDK 7 Support – JDK 6 required if using Interscope Tomcat 7 Spring 3.1 Hibernate 4.1 CXF 2.5

JDK 7 Try with resources Multi catch Nio 2 Fork Join Framework Better Dynamic Language Support Diamond ‘<>’ Operator Strings in ‘switch’

Tomcat 7 Servlet 3 support – Standard File Upload API – Java configuration – Improved servlet and filter patterns – Serve files out of jar – Async request handling – Many more! New lite JDBC Connection Pooler

Spring 3.1 Servlet 3 Improvements – Standard File Upload – Java configuration Spring MVC improvements – produce/consume – Flash Scope Configuration Profile Support Improved Java Config Cache abstraction

Hibernate 4.1 and CXF 2.5 Hibernate 4.1 – Internals significantly redone – Bugs have been fixed CXF 2.5 – Minor improvements

Merger of Stack 2 and Stack 3 Stack 2.x apps can be upgraded to Stack 3.2 Little or no code change Acegi replaced with Spring Security Develop and deploy on Tomcat Same libraries as Stack 3.2 Looks and feels like Stack 2 Supports all Stack 3 features and bug fixes

How to Upgrade 2.x app? Schedule time with member of Stack team Acquire Linux/Tomcat 7 environments Reserve: – 2-3 days for migration – X weeks for: New Environment setup Full QA regression test Several projects upgraded already!

What about Stack 2.x? Stack 2.3 is last planned 2.x release Websphere support is deprecated – No plans to support Websphere 8 Stack team will support 2.x forever Don’t expect new features Expect our condolences

DB Migrator 4.0 Support for timestamp based Migrations – No more arbitrary version number – Out of order Script Execution – Support for Feature/Release Branches Inherited db properties New Status Goal 11g Syntax Support Many other minor improvements Expect a Migrator 4.0 training in the future

DB Migrator 4 Demo

Distributed Cache Support What is a Distributed Cache? – Maintenance of cache state across a cluster Node 1 Node 2 DB Request 1 Name Change Name Node 1 Cache: Name: Mike Request Name Got Mike Changed to Fred

Distributed Cache Solution EhCache is the winner! – Simple library – Targets Caching – Pluggable cache transport Use Oracle Streams AQ (Buffered Msg) – Simple to set up Infrastructure doesn’t support Multicast Secure – Decent Speed (2 ms)

Distributed Cache Notes Works with Spring Cache Abstraction No Distributed Locking – Stable – No guaranteed cluster consistency – Upgrade to Ehcache+Terracotta if requirement No additional failure risk EhCache supports easy memory tuning – Tune by Heap % or MB

LDS Account Integration Refactor Support for Pure Java WAM client – No Spring Security dependency (Client Lib replacement) More Spring Security Friendly Support for user proxy feature Groundwork for future SAML support Many more minor tweaks and enhancements

Open Web Maven Plugin Plugin to support Open Web Stack team build Simple to integrate into build system Tested to be Eclipse and Intellij friendly Supports debugging of processed output Note: Requires Node.JS

Test Runner Simplifies management of application Functional Tests We have a ‘qa’ module isn’t that enough? – Only runs as part of build not post build – Difficult to match app build with matching tests

Test Runner Creates QA Test bundle Bundle is re-runnable – GUI, Maven, commandline, etc. Run functional tests against each environment Currently uses TestNG Works for Web UI and Service invocation tests Future: Support for updating Test Cases

Themes Upgrade Libraries Backwards Compatibility Improvements New and improved Tools Simplify build process and Improve build promotion orchestration

Build Improvements Removed all deploy and functional test plugins from default maven build – mvn install – builds artifacts and runs unit/integration tests Add new ‘alm’ module for post build task orchestration – New concept of ‘Build Promotion’ – Execute DB Migration->Deploy Application->Run Functional tests in one step – Project team has control of process

Build Promotion in Anthill Demo

Upgrade Notes Moderate risk upgrade from 3.1 Environments must be upgraded to Tomcat 7 – Scripts for ASEs available Use Upgrade Notes: – notes.html LDS Account Integration may require some work Simple upgrade won’t give you new build system

Summary Stack 3.2 builds on 3.1 New Features Upgraded Libraries Improved builds Schedule an Upgrade!
