Description
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a trans-container counter system credit migration method and equipment.
Background
Most of the counter application systems under the bank Windows platform are light business systems based on IE browsers and OCX controls (or IE browsers and NET Framework services), and the OCX controls may load and call a series of dependency libraries. Because IE browser, OCX control and NET Framework service can not be used in Linux system, a set of front-end peripheral calling system which can be used under the autonomous information creation platform architecture of domestic Linux system and domestic CPU must be established for counter system based on the requirements of information innovation and safety autonomy in the field of financial equipment. In combination with the light-weight requirement of the front-end system of the cabinet, the application system architecture pushes the B/S application architecture based on the open-source Chromium browser; in terms of peripheral calling, the mode of a middleware service and a common specification SP (drive service provider) framework commonly used on a letter and intelligence cabinet can meet the requirement of the cabinet front-end system for calling the peripheral, but the framework of the middleware service and the common specification SP usually needs at least one middleware service process and one SP process because of the requirement of decoupling of hierarchical processes, and the multi-process and multi-layer peripheral calling system framework can enhance the stability of the cabinet front-end system to a certain extent, but can support the stable and smooth operation of the cabinet front-end system by consuming a large amount of hardware resources; in practice, in the practical use process of the counter system, the middleware service and the SP mode of the common specification have the problems of slow response of frequent peripheral drive, incapability of starting, blocking of a service system and the like, and the framework is fully proved to be inapplicable to the requirement of the light system at the front end of the counter for calling the peripheral. Because the hardware resources of the bank counter machine are limited, peripheral services and drives are required to be simplified as much as possible, and the occupied hardware resources are less, the demand of application and peripheral drive credit migration and call is required to be solved for credit migration of the counter application system, and meanwhile, the demand of peripheral drive simplification is required to be met.
When the original Windows desktop system peripheral driver and the signal creation intelligent cabinet driver are updated remotely, failure is often caused by the difference of the environment of the terminal, so that the problem that the network point equipment cannot be used after version updating is often caused. For example, depending environment inconsistency caused by history version inconsistency, so that newly added peripheral services and SPs cannot operate normally; the end machine process is not thoroughly terminated, and partial file update failure is caused by insufficient authority; because of the network environment problem, the partial drive file may fail to download, resulting in incomplete peripheral service and SP after update and failure to operate normally.
The original Windows counter system cannot realize hot plug in the aspect of peripheral module switching: when the teller changes or inserts the peripheral model, besides the change of the hardware, a plurality of configuration files of the terminal machine are often required to be modified by a tool or manually modified, some driving files are copied or updated, and then the equipment is restarted to enable the modification to be effective. Therefore, the information creation migration of the counter system also needs to meet the hot plug switching requirement of the peripheral module.
