UNIX To Linux Application Porting Guide

Due to the high availability and powerful information processing capabilities, high-end fault-tolerance computers are widely used in important fields related to the people's livelihood, like bank systems, power systems and so on. However, Chinese high-end fault-tolerance computer market has been monopolized by foreign manufacturers. As the lack of the technology in these national products,national information security can't be guaranteed. The emergence of domestic high-end fault-tolerance computers,provides the possibility of information security. One of the main problems in the development, application and promotion of domestic high-end fault-tolerance computers, is how to port the current applications to domestic high-end fault-tolerance computers stably and reliably.The purpose of this paper is to provide porting guide, porting steps and testing methods for banks to migrate applications from current platforms to domestic high-end fault-tolerance computers. According to the project arrangements, the first phase of the application migration is to test application migration from IBM P 570 to HP RX 3600.This paper, takes the migration of the intermediate business integrated processing system in a provincial branch of a line for example, makes a comprehensive analysis on the differences between the source system and the target system in hardware platforms, operating systems and the building environment, providing the porting guide, and gives the porting steps and testing methods for the migration of IDS in the intermediate business integrated processing system of the bank.According to the porting guide, steps and testing methods provided in this paper, the migration of the intermediate business integrated processing system to HP RX 3600 has been completed and operated steadily and reliably for more than six months, the result shows that the achievements in this paper are correct and effective.
