Linux on power: Considerations for release version migration and binary compatibility

binary compatibility of Linux on power is achieved by following the application binary interface (ABI. Abi is an interface through which compiled binary files access the operating system and services. When multiple operating environments support the same Abi, you can run the same binary file in these operating environments. You can find the information about PowerPC executable and linking format (ELF) in "64-bit PowerPC elf application binary interface supplement 1.7) for more information, see

UNIX is 40 years old

. Although there were many other designs in 1990s, IBM did lag behind HP, sunAnd other vendors, the Unix Market in 1990s was in a fight situation. Over the years, IBM has been improving IBM's proprietary server-based hardware, using new architectures that actually require some mainframe components. HMC (Hardware Management Console) and system management programs (software for running and managing one or more operating systems on hardware machines) are important parts of the power architecture. T

This article provides two interesting scenarios that I have encountered and steps for detecting exceptions. Then stop, let you guess what went wrong, and finally give the answer. Example First, describe the two problems I encountered as a system administrator. Problem 1: the server is larger, but the com

How Oracle databases Authorize charges (database Licensing)

Oracle software itself is free, so anyone can download and install Oracle's database software from Oracle's official website, at a charge of license, which is software licensing, and if the database is for commercial use, it is necessary to purchase the license of the corresponding Oracle product.Oracle now has two modes of authorization, per CPU (Process) and per user (Named user Plus). The former is typically used in situations where the number of users is uncertain or the number of users is l

How to authorize charges for Oracle databases (DatabaseLicensing)

following describes the oracle's authorized Charging mode. Oracle software is free of charge, so anyone can download and install Oracle database software from the official Oracle website. The License is charged, that is, software authorization. If the database is used for commercial purposes, you need to purchase the License for the corresponding Oracle product. Currently, Oracle has two authorization Methods: by number of CPU (Process) and by number of users (Named User Plus ). The previous me

generates security issues related to user-defined functions in non-protected mode, this is because the thread mode allows malicious user code to read and write data pages without authorization. If you run user-defined functions in fensed mode, none of these problems will occur. The user code will be executed through a sub-process and communicate with DB2 through IPC, the only problem is that this is much slower than running in unprotected mode. When IBM's P

more important things? A: Our virtualization features are scalable, configurable, and can achieve predictable performance, which is what the customer really needs. Not only do you achieve higher utilization, you can also achieve predictable performance, which allows the right workloads to get resources in a resource-constrained environment. Virtualization can implement shared pools, while some applications can treat resources in these shared pools as dedicated resources, so they get resources

What is the difference between minicomputers and PC servers? (From entering the minicomputer world-Orian)

What is the difference between minicomputers and PC servers? From various performance evaluation indicators to the processing capability of a single CPU, minicomputers do not seem dominant. Why is it expensive?We can analyze the characteristics of performance, reliability, and scalability. For a single CPU, the Intel Xeon or AMD opteron used by PC servers is not inferior to the CPU performance used by minicomputers. However, the operating system released on the PC Server supports a maximum of 16

Windows multi-thread synchronization

Overview No single application can fully enable this processor. When a thread encounters a long wait event, synchronous multithreading also allows the commands in another thread to use all execution units. For example, when a thread encounters a high-speed cache miss, another thread can continue to execute. Synchronous multithreading is a function of the POWER5 and POWER6 processors and can be used with the shared processor. SMT optimizes the performa

There are two basic types of multithreaded processors: one is to emit instructions only from a single process in the loop, and the other is to emit instructions from

Case: Virtualization in key business applications

Dallas. Biddlecombe said the company is just about to upgrade its server hardware in this market. Therefore, it makes sense to implement virtualization when the server is upgraded. For transplace database applications, Biddlecombe converts the application from Sun's server (using the Solaris System) to IBM's mid-range servers (POWER6 processors and p570 servers running the AIX operating system). For Transplace's mid-range server, he switched from Su
