IBM CICS Transaction Server is a transaction processing server that operates primarily on IBM System Z mainframes based on IBM z/OS. It controls the interaction between an application and a user (from a small number of users to thousands). CICS applications provide high reliability and scalability. The CICS application is flexible and can use a variety of custome
Brief introduction
One of the advantages of IBM CICS is that it supports multiple programming languages and allows you to mix them into one application. However, if the CICS-based application uses only Java, you want to take advantage of the various CICS JAVA environments. When passing data between CICS programs, data
In the newly released CICS Transaction Server 5.1 release in December 2012, we addressed the needs of more than 100 global customers, including Chinese customers, and focused on two areas to address these issues: operational efficiency and agile services.
The CICS V5.1 enhances operational efficiency from four aspects,
First, CICS region capacity has been great

How should CICS write code when it needs to exchange these Chinese messages with the outside world with the HTTP protocol? This article is presented separately from CICS as an HTTP server and two aspects of the client.
First, explain a few important concepts:

Customer Information Control System (CICs) is a powerful host Transaction Server and integrated platform of IBM. It has a vast majority of customers in the transaction middleware markets such as C, C ++, and Cobol. CICs has over 30 years of history and is developed in IBMUKHursley R D center. The English pronunciation of CICs is kiks ". The
Memory leaks from Java programs can have serious consequences as well as memory leaks from other non-Java language programs. Although Java has a garbage collector, referenced objects can sometimes be reclaimed by the garbage collector. Therefore, to resolve memory leaks in Java programs, you first need to locate the memory leak and then identify the class that is causing the memory leak. This article takes a sample Java program running on the CICS JVM
Introduction
The CICS application has the same meaning as the service quality of the transaction; Integrating these applications with mainstream Java components is a common challenge for many enterprises today. You can use the Java Connector Architecture (JCA) and CICS Transaction Gateway to provide CICS applications and Java EE components deployed in WebSphere

In addition, the database administrator must be able to properly configure system installation, port and upgrade database software. The system is the cornerstone of an application. If the system cannot run well, all applications based on the system will run slowly and even cause program errors.

Vendors have recently begun to boast some conflicting ideas about mainframe migration. However, this will facilitate cross-platform applications on the mainframe.
Concept of mainframe migration
The key to mainframe migration is to provide a convenient way to port applications to Windows or Unix platforms at the source code level. Under this premise, the goal of these products will be to batch processing and Simulation of cobol cics. There are a vari

Middleware (IBM CICs, or BEA Tuxedo ), process the business parts that need to operate the database. For example, you can calculate the fees involved in an application form and then pass it to the front-end. The bottom layer is the database, and many large Oracl

Soft link:
The target file of the Ln-S source file can be used across file systems. Features: only an image of a file will be generated at the position you selected, without occupying disk space.
Commonalities:
Both symbolic links and hard links keep the files in sync.
Differences:
In addition to their respective features, the hard link result is that the target file has the same I-node as
The language Environment (LE) component of the z/OS operating system provides an application with a powerful set of run-time parameters (Run-time Option:rto) support. For developers, by setting the right RTO in the application, not only can you quickly see the run-time environment data, improve the efficiency of program debugging, but you can also set up a series of callable services provided by Le to handle exceptions and interrupts quickly.
1 RTO classification
LE RTO is mainly divided into
Environmental Products: DB2 UDB
Platform: z/OS
Version: V8
What are the ways in which the question executes the DB2 command?
The answer to the DB2 command can be done in the following ways:
1, through the z/OS of the console or z/OS applications, for the environment containing multiple DB2 subsystems. If you want to execute the DB2 command on a particular DB2 system, you need to use the command prefix, for example:-DSN1 DIS GROUP DETAILS. All DB2 commands can be executed.
2. All DB2 comman
