This article gives a brief evolution history of zos hardware,Main contents include: CPC, CHANNEL, STORAGE, CU, DEVICE, TAPEYou need to know how hardware is addressable;For example, the device X address is 132.Later, in order to increase IO performance, DIRECTOR and SWITCH were added as the intermediate buffer mechanism between channel and CU,It should be noted that DIRECTOR, SWITHCH is a data forwarding device, high-speed An ESCON director or FICON switch is a sophisticated device that can

About the virtual mainframe under Linux.We know that the Linux operating system is currently widely used on the server. is the virtual host under the Linux operating system what we often call a Linux virtual host? In fact, technically speaking, it's a virtual environment that's installed on Windows, and it's actually just a file. Let's look at some things about Linux and virtual hosting. First, let's look at the advantages of a Linux virtual host.Adva

The DB2 tutorial you're looking at is how to access the DB2 9 data server on a mainframe, mini-machine. The basic feature of the Database connection tool software DB2 Connect is to provide a way to connect interactive access between the database servers of the desktop application and the service host. The environment in which these desktop applications reside can be either windows,linux, or any of the UNIX. The personal version of the DB2 Connect to

  This article focuses on how to display the actual data in the memory. First, let's take a look at how the Assembly is implemented. The next step is to implement it using Cobol. 000000 00000 00100 1 main csectR: C 00000 2 using *, 12000000 90ec

To curb the further development of Linux in the enterprise's large-scale host market, Microsoft recently launched a strategic project called Microsoft's mission critical (MCM. Although this strategy is an internal project, it is likely to evolve

Many owners in the purchase of virtual host, will look at the virtual host some of the parameters, the most important is the support of the program language. Now many IDC businesses are claiming the almighty host. The most funny thing is that I just

1, the most common situation: The CPU fan dust is too thick, fan bearing aging caused by the computer host sound Big At present, most CPU radiators are installed with fans to achieve rapid cooling purposes. Computer use of a long time, the CPU

During the Second World War, there was a classic joke about conflicting military intelligence-the two opposite things could not be combined. The same effect can be achieved if "business" is used to replace "military. Some people think that it is

Article Title: Dynamic logical partitions on LinuxonPOWER. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Introduction　　By using a logical partition (LPAR), an IBM server with a POWER processor can support multiple system requirements on one machine. LPAR provides the a

Some peripherals on the small machine, such as the host machine and the optical drive, are rarely used at ordinary times, so most of them are shared among the LPAR of a small machine. These IO devices can only be exclusively occupied by one LPAR when used between different LPAR, so they must be switched when necessary.The customer's p6 570 server has four lpars,

network components are allocated from a shared pool of available resources on the physical machine. This allows you to integrate multiple workloads into a single server. Although large physical machines may require higher upfront costs, integrating many workloads into one server means more efficient use of system resources, this helps reduce power consumption, reduce data center space occupation, and ultimately achieve a lower total cost of ownership (TOC ). However, this paradigm introduces a

The method of adjusting affinity This section describes how to improve process-to-CPU affinity, CPU and memory affinity, and the affinity of virtual CPUs to physical CPUs. 1. Binding process For dedicated CPU mode, the binding process can be applied to the specified CPU. 2. Adjust CPU parameters For sharing CPU mode, do not set the CPU entitlement value too small when planning lpars. Minimize hypervisor dynamically adjust the amplitude of CPU resources, so that hypervisor when scheduling CPU res

The operating environment of the previous few posts is under IVM, IVM can be regarded as part of the Vios, or an extension to the Vios function, a IVM can only manage 1 physical servers, while the HMC is a one-to-many. In the case where the HMC is managing the physical server, the IVM feature in the Vios will be masked and its corresponding function will be taken over by the HMC.The following is a command to create a new lpar in the HMC environment:[E
