From a security perspective, IBM I provides three levels of security protection: physical security, logon security, and resource security. Physical security is from the hardware perspective, primarily involving the protection of IBM I data storage media; Logon security is user-centric, restricting who accesses IBM I and what to do after logging in; Resource secur

Compared with the traditional green screen IBM I applications, many modern IBM I applications are based on web technology, that is, the front-end uses a web-based graphical user interface, back-end reuse of traditional RPG and COBOL business programs. How to realize software reuse is an important goal of IBM I application modernization. On the one hand, the

Overview IBM Toolbox for Java is a collection of classes for developing Java applications related to IBM I. It includes tools that provide support for various scenarios such as IFS, IBM i System information, client/server, and users can easily use

In layman's terms, IBM I job management is responsible for handling system requests submitted by users or programs, which is one of the basic functions of the IBM I platform. Unlike Windows and UNIX, there are more concepts around IBM I job management, such as jobs, job descriptors, job queues, subsystems, subsystem descriptors, memory pools, output queues, and s

User authentication is one of the most basic functions to ensure program security for application developers engaged in IBM I platform. As a Java API,IBM Java Toolbox for access and manipulation of data and resources on the IBM I platform, a variety of user authentication st

As a set of Java application programming interfaces for the IBM I platform, IBM Java Toolbox for I is primarily used to access IBM I data and resources. The security of data and application is one of the important factors to be considered in

IBM Java Toolbox for I programming support for IBM I subsystem In addition to queues, subsystems are also a major feature of IBM I. IBM I supports multiple types of jobs to meet the needs of the user. Different kinds of job requirements for system resources are different, f

Process communication is a very important part of the operating system kernel. For IBM i, data queues are a very important way of process communication. On the one hand, data queues are powerful, are not limited by programming languages, and can simultaneously support synchronous communication and asynchronous communication between processes. On the other hand, data queues are flexible and their data messages are not tied to any format, in other words

IBM chief software designer Steve Mills: IBM has been worried for a long time that Oracle will be able to take a hard-hand approach to Java authorization. Last week, interarbor solution Chief Analyst Dana Gardner and IBM chief software designer SteveMills talked about Oracle's acquisition of sun and the future of

The IBM Developer Kit for the Java platform version 5.0 marks significant progress, with significant improvements in language features and low-level execution techniques. This article is the first in a 5-part article series that outlines some of the major changes and improvements IBM has made to its virtual machine technology, including traditional garbage collec

Source: IBM Tutorial Download SAX is what. The standard used to read and manipulate XML files is the Document Object model (Doc object model,dom). Unfortunately, the DOM method involves reading the entire file and storing the file in a tree structure, which can be inefficient, slow, and resource-intensive. An alternative technique is simple APIs for XML, or SAX. SAX allows you to

Bluemix automatically configures your container and binds your application as required. Final run interface results view:You can see the private ip/public IP that the container runs, as well as the ports used, the applications/services that are

", but it is not free. However, IBM also provides a free open-source database: Java-based Cloudscape. IBM turned it into open source last year. At the beginning of this year, IBM released a PHP development kit with a free DB2 license. It is reported that the database engine of Cloudscape is different from that of DB2,

According to TheRegister, Oracle recently announced that it would change the community management mode of OpenJDK, a leading open-source Java project, and share control of OpenJDK with IBM. IBM has been competing with Sun for nearly ten years for control of Java. The new OpenJDK provision is headed by MarkReinhold, chi

The following articles mainly introduce the basic tutorial of SQL coding optimization for the IBM DB2 database. The importance of such a specific query is that the more important the query is, you may need to optimize indexes by creating indexes. If you are coding the query that the CIO is running every day, make sure it provides the best performance. Therefore, it is important to create an index for this s

One of the goals of cloud computing is to allow developers to reduce the complexity of understanding and managing the hardware and software infrastructure so that they can focus on the functionality of the application. This goal has been achieved to varying degrees through the infrastructure, the service (IaaS) cloud and Peace Platform (PaaS) cloud. The IaaS cloud provides hardware and allows you to carry your own software. The PaaS Cloud also provides additional software that typically allows y

Steve MILLS:IBM, IBM's chief Software architect, will be worried for a long time about Oracle's heavy-handed approach to Java authorization. Last week Interarbor Solution chief analyst Dana Gardner with IBM Chief software designer Steve Mills about Oracle's acquisition of Sun and the future of Java. Mills believes Oracle, Sun's takeover deal will pass, but Mills
