Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
Example one
Fig. 1 is a schematic flow chart of a system migration method according to an embodiment of the present invention, where the present embodiment is applicable to a case where software and hardware are migrated, and the method may be executed by a system migration apparatus, where the apparatus may be implemented in a software and/or hardware manner, and may be integrated in an electronic device, and specifically includes the following steps:
s110, obtaining a structure in the system, and decomposing the structure to obtain an object to be migrated.
In this embodiment, the system includes an internet bank, a mobile phone bank, a telephone bank, a wechat bank, and other banking systems that use electronic service devices and networks to complete financial transactions by users in a self-service manner.
The structure in the system comprises:
optionally, the object to be migrated includes: a CPU, an operating system, middleware, a database, an application presentation layer, an application control layer, and an application data access layer.
In this embodiment, the object to be migrated needs to be changed from the original operating environment to the new operating environment, and since the hardware and software in the original operating environment and the new operating environment are different, in order to enable the system to operate normally, the object to be migrated needs to be decomposed and processed so as to adapt to the new operating environment. Wherein the objects to be migrated include hardware and software components.
The CPU (Central Processing Unit) is a final execution Unit for information Processing and program operation, and serves as an operation and control core of the computer system.
An operating system is a computer program that manages the hardware and software resources of a computer. The operating system needs to handle basic transactions such as managing and configuring memory, prioritizing system resources, controlling input devices and output devices, operating the network, and managing the file system. The operating system also provides an operator interface for the user to interact with the system.
The middleware is a kind of software between the application system and the system software, and it uses the basic service provided by the system software to connect each part of the application system or different applications on the network, so as to achieve the purpose of resource sharing and function sharing. Currently, it is not strictly defined, but the definition of IDC is generally accepted: middleware is a separate system software service by which distributed application software shares resources between different technologies, resides on the operating system of the client server, manages computing resources and network communications. In this sense, middleware can be represented by an equation: middleware is platform + communication, which defines that middleware can only be called in a distributed system, and also distinguishes the middleware from supporting software and utility software.
A database is a warehouse that organizes, stores, and manages data according to a data structure, which is an organized, sharable, and uniformly managed collection of large amounts of data that is stored in computers for a long period of time.
The application presentation layer is located at the sixth layer of the OSI hierarchy and one of its main roles is to provide a common language for heterogeneous machine communications to enable interoperability. This type of service is desirable because different computer architectures use different data representations. Unlike the fifth layer, which provides transparent data transport, the application presentation layer addresses all issues related to data presentation and transport, including translation, encryption, and compression. Each computer may have its own internal methods of representing data, e.g., ASCII code and EBCDIC code, so a presentation layer agreement needs to be applied to ensure that different computers can understand each other.
The application data access layer is the only entry that knows how to operate the storage medium, so to say, based on the data access layer, the method provided by the database access layer is called to complete the storage and reading of data,
the data access layer should be directly independent from the database. The data access layer must be able to persist data in the application program to the storage medium, and the data used is a relational database, but the model used is an object model.
S120, determining a migration strategy according to the original configuration and the target configuration of the object to be migrated.
In this embodiment, the original configuration is a configuration state in which an object to be migrated is initially located in an original operating environment, and the target configuration is a localization configuration state in which the object to be migrated is located in an existing operating environment, where the target configuration includes a localization core technology, a key component, and basic software and hardware.
In this embodiment, optionally, the migration policy includes:
direct migration, direct substitution, data migration, and adapted migration.
Optionally, the direct migration is that the object to be migrated is migrated from the original configuration to the target configuration while maintaining the original state, and no adjustment is made.
Optionally, the direct replacement is to directly replace the object to be migrated from the original configuration to the target configuration.
Optionally, the data migration is to migrate the database of the object to be migrated from the original configuration environment to the target configuration environment.
Optionally, the adapting migration is to migrate the object to be migrated from the original configuration to the target configuration after the object to be migrated needs to be adjusted.
S130, according to the migration strategy, migrating the object to be migrated from the original configuration to the target configuration.
In this embodiment, different objects to be migrated have different original configurations, different target configurations corresponding to the different objects to be migrated, and different migration strategies to be adopted correspondingly.
If the object to be migrated is a CPU, the object to be migrated is migrated from the original configuration X86_64 to the target configuration FT2000+64, and the migration policy is direct replacement. Where X86_64 is a 64-bit extension of the X86 architecture, backward compatible with 16-bit and 32-bit X86 architectures. X64 was designed by AMD in 1999, which first published a 64-bit set to extend to X86, termed "AMD 64". It was also used by Intel, now called "Intel 64", which was previously used by Clackamas Technology (CT), "IA-32 e" and "EM 64T". FT2000+64 adopts advanced reduced instruction set machine architecture, is compatible with 64-bit instruction set, integrates 64 processor cores independently designed by Feiteng corporation, has the core frequency of 2.0 GHz, the peak speed of floating point operation is 5120 hundred million times per second, and the actual measurement power consumption under the typical application condition is 100 watts.
If the object to be migrated is an operating system, the object to be migrated is migrated from the original configuration Rehat linux 6.5 to the target configuration kylin server 4.0.2, and the adopted migration strategy is direct substitution.
If the object to be migrated is middleware, the object to be migrated is migrated from the original configuration Oracle weblogic 12c to the BES 920, and the migration policy is direct substitution.
And installing a database object at the Db end to DM7.1, migrating the inventory data from the oracle, wherein the migration policy is data migration.
The application control layer is migrated from weblogic 12c to Bes 920, and the code is directly migrated and deployed without modification; the application representation layer carries out adaptive migration on the part configuration or code depending on weblogic; the data access layer completes data migration tests by using the DTS and the dmfldr, completes migration of database objects by using the DTS, completes data migration work of a table with a large data volume by using the dmfldr, and replaces the JDBC driver packet of oracle by using the JDBC driver packet of Dammame.
In this embodiment, specifically, the execution is based on java language. The Java is an object-oriented programming language, has the characteristics of the C + + language, and discards the concepts of multiple inheritance and pointers in C + +. Therefore, the java language has two characteristics of powerful function and simplicity and easiness in use, and the java language is used as a representative of the static object-oriented programming language and can realize the object-oriented theory.
