From an object-oriented perspective, IBM Java Toolbox for I provides a as400datatype interface to describe the specific transformation logic and rules between IBM I data types and Java data types. The implementation classes corresponding to the As400datatype interface can be roughly divided into: Numerical Text Date

the size in the production environment.Because the young generation uses a replication policy, the recovery speed is quite fast (minor GC), while the permanent generation uses a method similar to the optavgpause policy for concurrent flag and scanning, the collection speed is relatively slow (Major GC ). Ideally, the ratio of minor GC to major GC is around. (You can view the collected regions through GC logs) The tenure age and tilt ratio parameters of GENCON are dynamically adjusted by JVM. Fo

This article is designed to help those traditional lotusscript developers turn to Java development. With virtually no Java knowledge, this article can help you start Java application development in IBM Lotus Domino. Brief introduction For IBM Lotus Notes application develo

Brief introduction IBM Infosphere Streams (hereinafter referred to as Streams) is a highly reliable, highly scalable, distributed streaming computing platform launched by IBM in 2009 that proactively supports 6G per second or 21600G per hour (equivalent to the number of pages on the Internet) As the index of system design, processing ability realizes the ability of "eternal analysis" of streaming data. It

You can configure the garbage collection (GC) in IBM Developer Kit for the Java 5.0 Platform (IBM SDK) using 4 different policies. This article (the first of two articles on GC) introduces different garbage collection strategies and discusses their nature. Before reading this article, you should have a basic understanding of garbage collection in the

Extending IBM Dump Analyzer for Java using the analysis module Write your own analysis program Introduction: The first article in this series describes IBM dump analyzer for Java (or dump analyzer).

Integration with the Rational ClearQuest Test Manager (CQTM) system using the ClearQuest Java API via JNI technology Introduction: Rational ClearQuest is a defect and change management system, ClearQuest Test Manager (CQTM) runs as a model at the top level of ClearQuest V7. Its management capabilities cover the entire lifecycle of the test, including test planning, test authoring, test execution, and test reports. In order to be able to better use th

Introduction Many users who use IBM Java virtual machines often have the question of whether my program should use a 32-bit JVM or a 64-bit JVM. As we know, the 32-bit JVM has the following advantages over 64-bit JVMS: Fast boot speed Fast running speed For the same application, less system resources are consumed Obviously, the 32-bit JVM is the user's first choice. However, with 32-bit addressing, th

The concept of sharing a loaded class between Java virtual machine (JVM) processes is not new. For example, the Sun's CDS feature writes system classes to a read-only file, which is mapped to the JVM in memory. The Shiraz feature in the IBM z/os®1.4.2 JVM populates the class cache with a main JVM, which can then be shared from the JVM. The IBM implementation of

Introduction to the new features of IBM WebSphere application Server V7.0 Feature Pack for Java Persistence API 2.0 Object-Relationship persistence is an important part of Java EE application development. The Java Persistence API (JPA) is the object-relational persistent Java
