Technical Field

[0001] The patent of this invention relates to the field of data migration, in particular to a localized alternative migration method for a foreign-related technology application system. Background Art

[0002] With the development of application system technology, the iteration speed of application systems is getting faster and faster, and old low-security application systems will gradually be replaced by new secure and reliable application systems. In the process of replacing old and new application systems, that is, in the process of transferring the functions of old application systems to new application systems, there are problems caused by the migration and adaptation of application systems, and various compatibility and security issues caused by the migration of foreign computing platforms to independent and controllable confidential special computing platforms.

[0003] The existing method of domestic replacement and migration of application systems lacks assessment of confidential security during the migration process, resulting in the use of the replaced and migrated application systems in the work network of the procuratorate, posing a potential threat to the security of state secrets. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the present invention discloses a localization substitution migration method for a foreign-related technology application system.

[0031] In this document, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. The present invention is further described in conjunction with the accompanying drawings and embodiments:

[0032] A method for localization substitution migration of a foreign-related technology application system comprises the following steps:

[0033] S1) Preliminary assessment and analysis of the confidentiality level, scope and migration difficulty of the application system to obtain the conclusion of the application system replacement assessment;

[0034] S2) Based on the conclusions of the system replacement assessment, determine the system localization replacement plan and carry out adaptive migration and transformation to an independent and controllable secret-related special computing platform;

[0035] S3) Using the migration tool to migrate the database, and using the migration method to verify the database;

[0036] S4) Optimize the functions and performance of the application system to obtain a stable application system;

[0037] S5) Test the functions, interfaces, compatibility, performance, stability, reliability and other indicators of the alternative application system;

[0038] S6) Execute steps S4 and S5 in a loop to obtain an application system that meets the conditions.

[0039] Among them, in step S1, there are three evaluation conclusions for the degree of confidentiality: confidential, partially confidential, and non-confidential; there are two evaluation conclusions for the scope of confidentiality: wide confidential scope and narrow confidential scope; there are three evaluation conclusions for the difficulty of migration: migrateable, difficult to migrate, and non-migratable.

[0040]

[0041]

[0042] Step S1 also includes an evaluation of alternative implementation methods, which is determined as a full-function replacement or split-alternative implementation method based on the degree of confidentiality. For the application system that undergoes full-function replacement, all functional modules must undergo adaptive transformation and migration adaptation to an autonomous and controllable confidentiality-related special computing platform. After the adaptive transformation and migration, the application system has all the functions of the original system without deletions; for the application system that undergoes split-alternative implementation, only the confidentiality-related functions in the system are redesigned and adapted and migrated, and reorganized into an independently run application system. For non-confidential functional modules, no transformation or migration is required, and they can still run on the Wintel platform, waiting to be migrated as a whole to the non-confidential work network of the procuratorial organ in the future.

[0043] Step S1 also includes an alternative development mode evaluation, wherein the alternative development mode evaluation is determined as a migration mode or a reconstruction mode based on the migration difficulty.

[0044] Migration mode: Without changing the original technical architecture of the application system, the source code of the application system is adapted to the localized platform. This alternative R&D mode makes full use of the existing technical foundation and performs code adaptation and optimization for the localized basic software and hardware on the original software source code.

[0045] Reconstruction and replacement: completely abandon the original technical architecture of the application system, based on an independent and controllable confidential special computing platform, combined with the existing functional requirements of the application system, and redeveloped using a cross-platform technical architecture. This alternative R&D model basically scraps all the original R&D work, and the coding work starts almost from scratch. In addition, adaptation and optimization of the domestic platform are still required.

[0046]

[0047] Due to the objective existence of the two alternative R&D models and the advantages of the migration alternative model, the migration alternative model should be given priority when evaluating and determining alternative R&D models. Procuratorial organs at all levels need to understand and analyze the situation of relevant confidential application systems, including the basic environment in which the system currently operates, the software architecture and development framework used, the standards and specifications followed, etc., so as to evaluate whether the application system has the conditions to migrate to an autonomous and controllable environment.

[0048] Through preliminary evaluation, evaluation of alternative implementation methods, and evaluation of alternative R&D models, the conclusion of the application system alternative evaluation is obtained. The alternative evaluation conclusion includes the following contents:

[0049] 1. Basic information of the system, including confidential information of system function modules, user scale, adopted technical architecture, etc.;

[0050] 2. Preliminary assessment conclusions, including the system's confidentiality level, scope of confidentiality, and difficulty of migration;

[0051] 3. Alternative implementations of the system;

[0052] 4. Systematic alternative R&D model.

[0053] In step S2, the adaptive migration and transformation includes adaptive transformation of the front-end display layer, adaptive transformation of the middleware layer, adaptive transformation of the data access layer, and adaptive transformation of the operating system layer.

[0054] Adaptive transformation of the front-end display layer: mainly to achieve compatibility processing across browsers and browser versions, including compatibility adaptation at the CSS and JS code levels. Methods for achieving browser compatibility processing include: browser CSS style initialization, browser private properties, CSS hack syntax and automation plug-ins.

[0055] 1. CSS initialization: Use the library Normalize.css to set the style according to your needs. CSS style initialization can solve most of the common compatibility issues caused by the browser default style.

[0056] 2. Browser private properties: Add a prefix before the CSS property, as follows:

[0057] -moz-transform:rotate(-3deg); / *For Firefox* /

[0058] -ms-transform:rotate(-3deg); / *for IE* /

[0059] 3. CSS hack syntax: Write specific CSS styles for different browsers. The writing methods of CSS hack can be roughly summarized into the following types: conditional hack, attribute-level hack, and selector-level hack.

[0060] Conditional hack: mainly makes some special settings for IE browser;

[0061] Attribute hack: add some hack prefixes that only specific browsers can recognize before the CSS style attribute name;

[0062] Selector-level hack: This is a hack that adds some prefixes that only certain browsers can recognize before the CSS selector for browsers that have inconsistent page performance or require special treatment.

[0063] 4. Automatic plug-in: Use Autoprefixer, which is a plug-in that automatically manages browser prefixes. It can parse CSS files and add browser prefixes to CSS content. After adding Autoprefixe to the resource building tool (such as webpack), you can completely forget about the previous things and just write CSS normally according to the latest W3C specifications.

[0064] Adaptive transformation of the middleware layer: During the domestic substitution process, the application system developed based on the Java language has been deployed in the deployment package under Tomcat and can be used and migrated directly. However, the pre-compiled content containing JSP files cannot be opened and used directly, and needs to be recompiled and deployed under the domestic middleware environment.

[0065] Adaptive transformation of the data access layer: Adaptive transformation of the data access layer includes data structure migration and data access method adaptation. Data structure migration refers to the work of migrating the original non-localized database of the application system to the localized database. The localized database is generally equipped with a general database and a localized database migration tool, and the migration is completed through the migration tool. Due to differences in connection pools, the connection string, URL, database dialect, SQL statement, and JNDI configuration need to be modified during the database connection process.

[0066] Adaptive transformation of the operating system layer: Since the X86 architecture CPU instruction set is different from the domestically produced independently controllable CPU instruction set, during the implementation of domestic substitution, the application system functions involve program codes that call the underlying operating system instructions, such as:

[0067] 1. If there is content that calls the underlying function methods of the Window operating system, during the alternative implementation process, it is necessary to modify the interface function methods related to the characteristics of the operating system in the application system program code.

[0068] 2. After the domestic system is migrated, the print driver needs to be modified on the domestic operating system to implement the virtual printing function and upload the print job to the print server.

[0069] 3. After the domestic system is migrated, it is necessary to adapt the domestic operating system and modify the network card driver to send Layer 2 multicast messages to achieve efficient point-to-multipoint data transmission of network data packets, effectively saving network bandwidth and reducing network load.

[0070] In step S3, the database migration includes preparation before data migration, implementation of data migration, and verification and backup after data migration.

[0071] Preparation before migration: including analysis and determination of the amount of data to be migrated; establishing a mapping relationship between database tables and performing data checks between systems; preparing tools for data migration and writing test plans and verification procedures for data migration; conducting quality analysis of historical data and determining whether to use manual, semi-automatic or fully automatic methods for data cleaning, organization and conversion.

[0072] Implementation of data migration: data migration from the existing system to the new system. Example steps for implementing data migration: 1. Confirm that the SQL Server version is consistent. The number returned by select@@version must be the same. It is necessary to ensure that the restored master and msdb are consistent with the original database, otherwise SQL Server cannot work properly; 2. Stop the service and start in single-user mode; 3. Connect to the SQL Server instance; 4. Restore the madter database; 5. Start with trace flag 3608; 6. Sqlcmd connects to SQLServer; 7. Find the database file path on the original instance; 8. Modify the correct path of the system database; 9. Stop the service and start in normal mode; 10. Restore the database; 11. Modify the server name; 12. Restore all user databases; 13. Check after migration is completed to check whether all original logins can log in successfully, and whether objects such as linked servers, database triggers, endpoints and jobs have been migrated successfully.

[0073] Verification and backup after data migration: Verification after data migration is an inspection of migration quality. The result of data verification is also an important basis for judging whether the new system can be officially launched. At the same time, the migrated data is backed up to avoid data loss.

[0074] In addition, in step S3, the database is verified using a migration method, and the verification includes database objects, indexes, data, and stored procedures.

[0075] Steps to implement database verification example: 1. Judge from the total number to see whether the total number of user objects such as tables, views, stored procedures, stored functions, triggers, etc. before and after migration corresponds to the source database; 2. Count the total number of records in each table and compare the number of rows; 3. For views, stored procedures, functions, etc., their DDL statements can be exported into txt readable files, and then compared through text comparison tools; 4. Compare the contents of database tables using mysqldiff+mysqldbcompare tools.

[0076] In step S4, after completing the relevant adaptive transformation, optimization work is carried out on the functions, performance, stability and other aspects of the application system, and finally a stable application system is obtained.

[0077] The optimization of the application system includes front-end page optimization, database optimization, business process optimization, operating system optimization, and middleware optimization.

[0078] Front-end page optimization: mainly includes page optimization of page style, JS scripts and other related parts. 1. The optimization of page style mainly completes the optimization adjustment from the original non-localized environment to the domestic basic operating environment from four aspects: CSS file placement, static image display, page element display, and page dynamic effects; 2. The optimization of JS scripts mainly completes the optimization adjustment from the original non-localized environment to the domestic basic operating environment from three aspects: JS rendering, display script, and JS application; 3. The optimization of other aspects mainly completes the optimization adjustment from the original non-localized environment to the domestic basic operating environment from six aspects: information loading method after login, JS, CSS file application method, page DOM elements, page staticization, static resource cache application, and page information loading method.

[0079] Database optimization: mainly includes optimization and adjustment in three aspects: index optimization, SQL statement optimization and database configuration. 1. Index optimization: add indexes to query condition fields, connection fields between tables, and sorting fields, and create reverse indexes for reverse sorting; 2. SQL statement optimization: change the primary key of the main table to a sequence, so that the size order of the primary key sequence is the same as the creation time order. The time sorting can be replaced by sorting the primary key, and the records retrieved are implemented in the same way as the original system; 3. Database configuration optimization: modify the three configuration parameters of the number of data buffer pages, the maximum memory for executor sorting, and the maximum number of connections. Ensure that the system runs normally under large concurrency and avoid database downtime.

[0080] Business process optimization: mainly includes optimization and adjustment of business and database interaction methods and lazy loading technology. 1. Business and database interaction methods: merge multiple interactions with the database to ensure that one database query operation completes the retrieval and display of all information; 2. Lazy loading technology: Lazy loading technology will bring pressure of multiple requests to the database. In order to avoid database server downtime, all attributes of the object need to be queried at one time to reduce the number of database interactions.

[0081] Operating system optimization: The optimization of the operating system mainly involves adjusting and optimizing the compilation environment used by each application system, while also performing code optimization and adjustment.

[0082] Middleware optimization: Business process optimization mainly includes optimization and adjustment in several aspects, such as thread pool configuration, database connection pool configuration, log configuration, and JVM tuning.

[0083] In step S5, the critical indicators of the original Wintel platform system in the actual production environment, such as the number of online users, the number of concurrent users, and the amount of business data, are recorded as the test verification standard for the completion of the adaptive transformation of the application system. Benchmarking the original system functions and performance indicators, writing test cases, and fully testing the adaptively transformed and optimized application system.

[0084] The alternative testing of the procuratorial organs’ confidential application systems mainly includes testing of application system functions, interfaces, compatibility, performance, stability, reliability and other indicators.

[0085] Functional testing: By designing test scenarios for each application system, the main application business flow of the system is verified, thereby covering all functional points of the system and verifying the system function availability.

[0086] Interface testing: Interface testing includes internal interfaces and external interfaces, testing of data interfaces within the application system and between application systems, and testing the correctness of data interfaces between systems based on the interface interaction descriptions between systems.

[0087] Compatibility testing: compatibility between domestic terminal platforms and non-domestic terminal platforms, including compatibility testing of browsers, electronic document standardization kits and basic office software.

[0088] Performance testing: From the perspective of user application experience, performance testing includes single-user function operation response time and concurrent user function operation response time. Test the application system under a certain load condition by recording a simulated concurrent test script, and then use the test tool to extract whether the response time of each function operation of the application system meets the test index requirements. Performance testing tests various performance indicators of the system by simulating a variety of normal, peak and abnormal load conditions.

[0089] Stability test: Verify the overall stability of the application system. Use the test tool to record simulated concurrent test scripts and run 7*24 hours stability test under a certain load. At the same time, the application system's daily business can be used normally, and the system resource usage is monitored to provide data support for the stable operation of the system after it goes online.

[0090] Reliability test: Verify the system's ability to automatically switch and recover from various abnormal failures. Under a certain load, simulate the failure of domestic database servers, application servers and other equipment resources, and automatically switch without affecting daily business use. When the database server, application server and other equipment fail, they can automatically recover without affecting daily business use.

[0091] Among them, in step S6, the conditions include normal operation and provision of services based on a localized environment, substantially no change in the original system usage habits, and providing a functional processing efficiency no less than that of the original system.
