2010-12-12 Sunday - Oracle 11gR2 Streams

Today I'm researching some problems that have cropped up during recent maintenance / testing of an Oracle Streams implementation (running on IBM AIX).

Of course, its always good to start with the offical Oracle documentation:

The following articles are important to review:

Tasks to Complete Before Configuring Oracle Streams Replication

9 Oracle Streams Conflict Resolution

12 Managing Oracle Streams Replication

I'm also ordering the following two books from Amazon:

Oracle 11g Streams Implementer's Guide (January 2010)

2010-12-06 Monday - Java Heap Dump Analysis

Today I'm helping a Performance Testing Team do some research on a possible memory leak in a 3rd party application suite - and wanted to review some of the tools that might be of some assistance in my analysis.

This posting is a placeholder for my notes:

.PHD = Portable Heap Dump format
(started with Java SDK 1.4.2 SR1)

A tool for debugging memory leaks in Java applications through analysis of "heap dumps."


JavaOne 2009 - TS-4118 Practical Lessons in Memory Analysis
(site appears to be under maintenance)
"In order to analyze IBM system dumps with Memory Analyzer, one needs to install the DTFJ adapter into the Memory Analyzer. The DTFJ adapter as well as installation instructions are available here."

Using the IBM DTFJ with the Eclipse Memory Analyzer Tool
(not sure if this is still needed - or if Eclipse MAT has already incorporated this dependency)
"The Eclipse Memory Analyzer Tool (MAT) is an open-source Eclipse project for analyzing heap dumps and identifying memory leaks from Java virtual machines. The basic MAT installation only works with Sun HPROF binary dumps. Using the IBM Diagnostic Tool Framework for Java (DTFJ) enables MAT to work with system dumps and Portable Heap Dump (PHD) files from IBM Virtual Machines for Java version 6, version 5.0 and version 1.4.2."

2010-10-20 Wednesday - VMware and GoogleNews from SpringOne Developer Conference

VMware and Google Advance Cloud Computing

The two companies announcing general availability of key Java development tools for cloud portability

CHICAGO, Illinois—October 21, 2010 Today at the SpringOne 2GX developer conferenceVMware, Inc. (NYSE: VMW), the global leader in virtualization and cloud infrastructure, announced with Google the general availability of the first in a series of technology collaborations to make enterprise software developers more efficient at building, deploying and managing applications within any cloud environment on any device. The collaborative projects that will be available in the next two weeks include Spring Roo and Google Web Toolkit, Spring Insight and Google Speed Tracer, SpringSource Tool Suite and Google Plugin for Eclipse.  
“Together, Google and VMware enable enterprises to develop and deploy rich Spring Java applications across multiple clouds and devices.” said Rod Johnson, SVP, application platform division at VMware. “Today we have reached an important milestone where these modern applications can run smoothly within the firewalls of a company’s production datacenter or in a trusted provider's cloud environment." 
The general availability of these projects represents the first in a series of technology collaborations to enhance cloud portability accross multiple clouds and devices. The next collaboration projects will focus on even broader mobile application support and accessing data in the cloud, as demonstrated today by the ability to deploy a SQL-based Spring application on Google App Engine for Business. 
“Developers are looking for faster ways to build and run great web applications, and businesses want platforms that are open and flexible,” said Vic Gundotra, Google vice president of developer platforms. “By making deployments of Spring Java applications on Google App Engine using Google Web Toolkit generally available, developers can deploy Java applications in production environments of their choice while leveraging rich web front-end across multiple devices.”
The following projects will be Generally Available within 2 weeks:
Spring Roo and Google Web Toolkit - Spring Roo, a next generation rapid application development tool, combined with the power of the Google Web Toolkit (GWT) enable developers to build rich browser apps in enterprise production environments. These GWT powered applications leverage modern browser technologies such as AJAX and HTML5 to create the most compelling end user experience on both desktops and mobile browsers.
Spring Insight and Google Speed Tracer - Google’s Speed Tracer with VMware’s Spring Insight performance tracing technology, enable end to end performance visibility into cloud applications. This integration provides a holistic view into the web application performance, improving the end-user experience by optimizing the client side as well as the server side. 
SpringSource Tool Suite and Google Plugin for Eclipse - The integration of SpringSource Tool Suite version 2.5 and Google Plugin for Eclipse makes it easy for developers to build and maintain large scale, web-based, enterprise applications, putting tools that were previously only available when building desktop and server solutions in the hands of those building cutting edge web apps.

2010-10-03 Sunday - Book Review: Java EE 6 with GlassFish 3 Application Server

Java EE 6 with GlassFish 3 Application Server, by David Heffelfinger
Packt Publishing
"A practical guide to install and configure the GlassFish 3 Application Server and develop Java EE 6 applications to be deployed to this server"

This book strives to cover much - if you are new to Java EE 6 - this may be a useful introductory text that can provide a broad overview of the core technologies - and in particular - a great companion to learning how to use GlassFish 3.

As the following chapter list illustrates, this book attempts to aggressively cover a broad spectrum of Java EE technologies:

Chapter 1: Getting Started with GlassFish

Covers the various processes for deploying Java EE applications, and basic GlassFish administration tasks.

Chapter 2: Servlet Development and Deployment

Covers how to develop, configure, package, and deploy servlets, using servlet context to persist information between requests - also covers the major new features of Servlet 3.0

Chapter 3: JavaServer Pages

Chapter 4: JSP Standard Tag Library

Chapter 5: Database Connectivity

Covers Java Database Connectivity (JDBC), Java Persistence API (JPA), as well as Java Persistence Query Language (JPQL)

Chapter 6: JavaServer Faces

Also covers integrating JSF and the Java Persistence API (JPA)

Chapter 7: Java Messaging Services

Chapter 8: Security

Covers he GlassFish default realms, file realm, and the certificate realm.  Creation of additional realms is covered via the realm classes included with GlassFish.

Chapter 9: Enterprise JavaBeans

Chapter 10: Contexts and Dependency Injection

Covers how JSF pages can access CDI named beans (as JSF managed beans)

Chapter 11: Web Services and JAX-WS

Covers sending attachments to a web service, exposing EJB's methods as web services, and how to secure web services from unauthorized clients.

Chapter 12: RESTful Web Services and Jersey and JAX-RS

Covers leveraging Java API for XML Binding (JAXB) to simplify integrating data between Java and XML.

Appendix A: Sending E-mails from Java EE Applications

Appendix B: IDE Integration

At 489 pages, this book is necessarily more of a survey of Java EE 6 development topics - with insight into the corresponding configuration and deployment aspects for the GlassFish 3 Application Server. It is a handy reference for both the beginner and advanced user of GlassFish application server.

The code for the book can be downloaded here:

For a more in-depth treatment of GlassFish Administration, Packt Publishing offers another book (by  Xuekun Kou), which I also recommend:

SMArt (Subsitutable Medical Apps, reusable technologies)
"...project funded by The Office of the National Coordinator for Health Information Technology through the Strategic Health IT Advanced Research Projects (SHARP) program. The conceptual framework for SMArt was first articulated by investigators Zak Kohane and Ken Mandl in their 2009 New England Journal of Medicine essay “No Small Change for the Health Information Economy”. The current health IT landscape is characterized by monolithic and slow-to-evolve systems: SMArt has brought together researchers, industry partners, clinicians, and other stakeholders to lay the groundwork necessary to enable a tectonic shift to a flexible health IT environment. The major deliverable of this project will be the SMArt platform architecture, which will achieve two major goals. The first will be a user interface that will allow “iPhone-like” substitutability for medical apps based upon shared basic components. The second will be a set of services that enable efficient data capture, storage, and effective data retrieval and analytics, which will be scalable to the national level but nonetheless respectful of institutional autonomy and patient privacy."

Today I've spent some time researching the Nationwide Health Information Network

CONNECT is an open source software solution that supports health information exchange – both locally and at the national level. CONNECT uses Nationwide Health Information Network standards and governance to make sure that health information exchanges are compatible with other exchanges being set up throughout the country.
This software solution was initially developed by federal agencies to support their health-related missions, but it is now available to all organizations and can be used to help set up health information exchanges and share data using nationally-recognized interoperability standards.

The CONNECT source code repository can be accessed here:

2010-09-20 Monday - JavaOne 2010: Java 7

10am-11am, Hilton Hotel Grand Ballroom

[I'll flesh out more details as I have some time later today to add additional reference links]

- Grand Ballroom is huge
- about 99% full, good turn-out for this JavaOne session
- speaker sounds like he took a valium needed to drink a jolt-cola before taking the stage...


Project Lambda
version 0.1 
JSR 292
"The goal of this Project is to formulate a proposal to add first-class functions, function types, and lambda expressions (informally, "closures") to Java, and to implement a prototype suitable for inclusion in JDK 7 so as to enable broad experimentation. If all goes well then this will serve as the basis of a language-change JSR which will, in turn, be proposed as a component of the eventual Java SE 7 JSR."

Alex Buckley and Brian Goetz will be giving a talk later today  at 4pm...


De Vinci Machine Project
"a multi-language renaissance for the Java™ Virtual Machine architecture"

"We are extending the JVM with first-class architectural support for languages other than Java, especially dynamic languages. This project will prototype a number of extensions to the JVM, so that it can run non-Java languages efficiently, with a performance level comparable to that of Java itself. Our emphasis is on completing the existing bytecode and execution architecture with general purpose extensions, as opposed to a new feature for just one language, or adjoining an unrelated new execution model." "We want the new languages to co-exist gracefully with Java in the JVM, and to benefit (like Java) from its powerful and mature technologies." "We are looking to remove “pain points” already observed by implementors of successful or influential languages, as opposed to attempting more speculative work on unproven features or niche languages. Sub-projects with major activity include dynamic invocation, continuations, tail-calls, and interface injection.  There is a large number of more speculative, lower-priority sub-projects. These are included in hopes that someone in the community will become excited with us at the prospects of a more dynamic JVM, to the point of sharing in its creation."


Project Jigsaw
"get rid of the classpath....put the information in the code as annotations" (?)
"The goal of this Project is to design and implement a simple, low-level module system focused narrowly upon the goal of modularizing the JDK, and to apply that system to the JDK itself. We expect the resulting module system to be useful to developers for their own code, and it will be fully supported by Sun for that purpose, but it will not be an official part of the Java SE 7 Platform Specification and it might not be supported by other SE 7 implementations."


The JPackage Project has two primary goals:
  • To provide a coherent set of Java software packages for Linux, satisfying all quality requirements of other applications.
  • To establish an efficient and robust policy for Java software packaging and installation. 

JMod (?)
...more compressed than JAR files...
...allow creation of JPMs
...will be allow generation via Maven

...HotSpot will get an injection of HotRocket code/capabilities...

Java 7 Release...

...original scope would have been delivered in middle of 2012...that's too long...
...... Lambda is not done
.......Jigsaw is not done
.......Coin is almost done (?)

...deliver what can be made middle of 2011...
...deliver Java 8 in 2012
...deliver Java less than 5 years...
...wants to get back to a more regular release schedule (every 2 years...)

GPL version 2 will continue to be used

Still plan to submit JSRs for Java 7 and future releases

JDK 7 binaries will continue to be released every two weeks for testing...

2010-09-19 Sunday - A Shadow of JavaOnes' Past...

I arrived in San Francisco yesterday via my flight from Phoenix.  On my drive into the city, a cab driver mentioned that he had heard that as many 42,000 people will be arriving for the OracleWorld conference this week.  I am primarily interested in the JavaOne sessions - but will also attend some of the Oracle Developer sessions - as well as the OracleWorld key notes.

JavaOne, I feel I hardly know ye - I fear you are but a ghost of your former self...

As I look through the catalog of sessions for JavaOne 2010, I am saddened to see that the Birds-of-a-Feather (BOF) sessions are limited to just Tuesday night...

By virtue of having JavaOne sessions scheduled at locations such as the Hilton, Parc55, and Westin - rooms are probably smaller (?) than what would normally have been available at Moscone Center - thus sessions are marked as FULL - that might otherwise have had a bit more room for the random drop-in attendee.

I'll be attending the Oracle Opening Keynote tonight...the after-party will be held here?...

Familiar faces from Sun are missing here this week, Google's absence from the list of sessions is noticeable, and the side-show feeling of JavaOne sessions no longer being held in Moscone Center cast a pall over this year's JavaOne for me...

2010-09-11 Saturday - Winter'11 Release Notes

I'm doing an evaluation this weekend of for a client's possible use in their adoption of

As part of that evaluation, I spent some time reviewing the Winter'11 Release Preview information:

I've extracted a few items from the release notes that caught my attention:

With Winter '11, developers and partners can use a new CTI Developer's Toolkit to build CTI adapters for call center users working with the Service Cloud console
In Winter '11, the High Volume Customer Portal User license is generally available. After you purchase the license, you can assign it to Customer Portal-enabled contacts so that large numbers of users can log in to a Customer Portal without affecting its performance.

Revised Governor Limits
For Winter '11, is reducing the number of items limited by the Apex governor limits. In addition, many of the remaining items have had their limits increased.

Tests no longer run in a separate context: Prior to Winter '11, governor limits worked with three different contexts, with different amounts of resources allocated for each context. For Winter '11. tests no longer have specific limits. Instead, they've been included with triggers, anonymous blocks, Visualforce controllers, and WSDL methods.

Removed limits:
• Total request time for one callout (HTTP request or Web services call) has been removed.

• Maximum size for a callout (HTTP request or Web services call) has been removed.
Increases to existing limits:

• General heap size has been raised from 2 MB to 3 MB, with no scaling. In addition, batch Apex heap size is 6 MB.

• Apex classes and triggers have been raised from 100,000 characters and 32,000 characters, respectively, and can now be 1 million characters long, not counting comments, test methods, and classes defined with @isTest.

• Maximum amount of Apex code allowed in an organization has been raised from 1 MB to 2 MB.

• Total number of ChildRelationship, RecordTypeInfo and PicklistEntry objects allowed and total number of fields calls allowed has been raised from 10 to 100.


New AllOrNoneHeader SOAP Header
The AllOrNoneHeader header allows the create(), delete(), undelete(), update(), and upsert() calls to roll back all changes unless all records are processed successfully. The default behavior is to allow partial success of a call: Web Services API Enhancements
records without errors are committed, while records with errors are marked as failed in the call results. This new header gives you more transactional control over commitment of changes.

Page-118 Bulk API Enhancements
The REST-based Bulk API is optimized to process a large number of records asynchronously. It allows you to load large batches of data that are processed in the background. The Bulk API has been improved for API version 20.0:
  • Support for Binary Attachments

  • With API version 20.0, you can submit batches containing binary attachments, such as Attachment records or Salesforce CRM Content.

  • Increased Number of Daily Batches Allowed

  • The limit of batches allowed per rolling 24–hour period has been increased from 500 to 1000.

Page-120 uses the SAML 2.0 standard for single sign-on and generates SAML assertions when configured as an identity provider.

OAuth Version 2.0 Supported
Starting in Winter '11, supports version 2.0 of the OAuth protocol for authenticating Web applications that access data in a instance.

A wealth of documentation is available:

While attempting to test the command line utilities, I encountered the following error message popping up rather unexpectedly:

"mspdb100.dll is missing..."

A quick search found this posting on Microsoft Connect - which indicated that the directory where the IDE is installed simply needed to be added to the PATH.

On a side note, I recently installed PowerISO - and highly recommend it.
