Ann: ECperf Uncovered Whitepaper

Question

Dublin, Ireland, September 4, 2002 Inspired today announced that it is making available a white paper, ECperf Uncovered which provides an insight into the transactional execution plans of 3 application server vendors - BEA, Borland and Pramati.

The white paper comes packaged with a console only version of JDBInsight 1.2. Included in the packaging are 3 ECperf performance profile snapshots, BEA WebLogic 7.0, Borland BES 5.02, and Pramati 3.0, used in the production of the white paper. Readers are encouraged to use the console in conjunction with the white paper.
Inspired has also announced that the next release of JDBInsight will include a developer edition priced at 150 USD to allow JDBInsight to be used throughout the development lifecycle. With this announcement developers can start to target J2EE performance bottlenecks, JDBC resource bugs, and incorrect persistence mappings from the start, further reducing overall development costs.
About JDBInsight
============
JDBInsight is an innovative enterprise development product, aimed at simplifying the performance tuning and testing of J2EE applications, which access data through the Java Database Connectivity (JDBC) API. JDBInsight analyses the access of enterprise data by J2EE client-, web-, and bean containers. The analysis can encompass transaction executions, spanning multiple J2EE containers. JDBInsight captures timing and execution information for enterprise data accessed by Servlets, JavaServer Pages, Session- and Entity Beans using JDBC or an Entity Bean using a container's persistence engine.
JDBInsight provides the ability to quickly detect performance bottlenecks within a J2EE system, reducing the need to hire expensive performance tuning consultants, allocating valuable development resources or purchasing further hardware to compensate for lack of tuning. It aids testing by providing the ability to create snapshots of the database interaction during test runs.
Reason for Choosing JDBInsight
===================
Minimal Performance Overhead - During performance test runs of ECperf, JDBInsight introduced as little as 2% overhead to the runtime. Similar runs with open source solutions showed 50% degradation in the throughput figures. Using a Java profiler would result in an even greater degradation, rendering any profiling information useless.
Early Detection - Unlike most other J2EE performance assurance offerings, JDBInsight enables development teams to target performance from day one. Since most tuning efforts result in changes to application design and code, it is important this is addressed early, rather than late. JDBInsight enables project management to control development time and hardware costs.
Targets Biggest Bottleneck - Java profilers in most cases cannot identify application bottlenecks even with application server class and package filtering. The information that is provided is usually incomplete and without context. JDBInsight focuses specifically on the expensive interaction between applications and databases.
Visualizes the Invisible - With the increasing usage of persistence frameworks in J2EE application development, architects and developers find it impossible to determine what database interactions are occurring. One of the biggest problems is that the inner workings are encapsulated, thus testers are limited to black box testing, slowing down development. JDBInsight provides a visualization of the transactional nature of a J2EE application, unmatched by any other similar offering.
Application Server and Database Independent - JDBInsight allows developers to identify poorly performing SQL, independent of database and trace tools. J2EE developers need not configure a database for tracing, nor spend time learning different tools for extracting traces. JDBInsight goes far beyond the sophistication of current database tracing tools, by compacting transaction history trees and providing detailed statistics at various levels of detail. Developers using different application servers also benefit from the fact that the product is application server independent.

Answer 1

I just retried the link which I posted here.
Under the header "ADF Data Binding Primer Article", click on the hyperlink that says "article". That should get you to the paper.
I will be updating the BC4J Toy Store for 10g sometime between now and production, yes.
You can already open it in JDeveloper 10g, and use the visual Struts page flow diagram to see it's pages and actions. After upgrade, it will still be using the direct ADF AppModule (9.0.3-style) data binding, but this style continues to work fine in 10g.
