The embodiments described above are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

This embodiment of the present invention describes an upgrade control method applied to application system migration. Please refer to FIG. 1. The above upgrade control method includes:

Step 101, obtaining system information of the application system to be migrated currently;

Wherein, the above-mentioned system information includes: information used to indicate each program to be upgraded in the above-mentioned application system. It should be noted that the programs in the embodiments of the present invention include but are not limited to system programs and application programs. The “upgrade” mentioned in the embodiments of the present invention refers to a series of program-related programs including program upgrade, patching, and plug-in update. update operation.

In the embodiment of the present invention, the application system is composed of a hardware system, a system program, and an application program. Among them, the hardware system is composed of arithmetic unit and controller, memory, peripheral interface and peripheral equipment. System programs include operating systems, compilers, database management systems, and various high-level languages. The application consists of general support software and various application packages. Optionally, the application system in this embodiment of the present invention may also specifically refer to a cloud system (in some scenarios, a cloud system is also referred to as a cloud computing operating system and a cloud computing center operating system).

In step 101, by traversing the application system globally, the status of the application system (for example, which programs need to be upgraded, the situation of each program on system resources, the dependencies between each program, etc.) to indicate the system information of the information of each program to be upgraded in the above application system. Further, the above-mentioned system information may also include any one or more of the following information: the occupancy of system resources by each program to be upgraded (for example, the proportion of system resources occupied by each program to be upgraded), the relationship between each program to be upgraded dependencies. Among them, the dependencies between each program determine the upgrade sequence between each program, for example, Tomcat (Tomcat is a free and open source Servlet container, and has the function of a traditional Web server) and MySQL (MySQL is a relational database management system), so that Tomcat cannot be upgraded until MySQL is upgraded. Specifically, the dependencies between the programs can be pre-standardized in the installation packages or configuration files of the programs, and the dependencies between the programs can be obtained by analyzing the installation packages or configuration files of the programs.

Step 102: Based on the obtained system information, search for an upgrade template matching the above system information in a preset template database;

Wherein, two or more upgrade templates are stored in the above-mentioned template database, and each upgrade template includes: an upgrade scheme related to one or more than two programs.

In the embodiment of the present invention, various upgrade templates may be generated and stored in the template database in advance based on the historical experience of application system migration and/or the collection and analysis of system information of each application system. Wherein, each upgrade template includes: an upgrade scheme related to one or more than two programs. The upgrade scheme can be used to guide the upgrade process of the corresponding one or more programs (for example, when to upgrade, how to upgrade, etc.).

In step 102, since the system information includes the information of each program to be upgraded, and the upgrade template includes upgrade schemes related to one or more programs, the system information obtained in step 101 can be obtained from the above template database Find an upgrade template that matches the system above. For example, according to the information indicating each program to be upgraded included in the system information obtained in step 101, an upgrade template including an upgrade scheme related to the corresponding program can be searched from the template database.

In an application scenario, the above-mentioned system information further includes: information used to indicate a dependency relationship between various programs to be upgraded, and the above-mentioned system information is represented in a graph, and the above-mentioned upgrade template further includes: one or a Dependencies of more than two programs. Step 102 may be represented as: searching for an upgrade template matching the above system information in a preset template database based on the image similarity algorithm and the obtained system information (ie, the system information obtained in step 101 ).

Further, considering that an application system may contain many programs to be upgraded, the programs with dependencies may be clustered in advance through a clustering algorithm. Specifically, the above-mentioned searching for an upgrade template matching the above-mentioned system information in a preset template database based on the image similarity algorithm and the above-mentioned system information includes: dividing the graph representing the above-mentioned system information into two or more pieces through a clustering algorithm Sub-images; for each sub-image, an upgrade template matching each sub-image is searched in the preset template database based on the image similarity algorithm. The above-mentioned clustering algorithm may be, for example, the Min-Cut algorithm, the LDA algorithm or other clustering algorithms, which are not limited here.

Step 103: If an upgrade template matching the above-mentioned system information is found, upgrade the program to be upgraded in the above-mentioned application system according to the above-mentioned upgrade template;

Since the upgrade template includes an upgrade scheme related to one or more than two programs, the upgrade scheme can be used to guide the upgrade process of the corresponding one or more than two programs (eg, when to upgrade, how to upgrade, etc.). Therefore, when an upgrade template matching the above-mentioned system information is found in step 102, corresponding upgrade processing can be performed on the program to be upgraded in the above-mentioned application system according to the above-mentioned upgrade template.

Further, during the upgrade process in step 103, potential upgrade conflicts can also be automatically discovered and resolved, so that the same program can be upgraded at most once. Specifically, the upgrade control method in the embodiment of the present invention further includes: when there are multiple upgradeable versions of the same program, traversing the dependency relationship between the same program and other programs currently to be upgraded to minimize the number of upgrades A target version is determined from a plurality of upgradable versions of the same program as a criterion, and the same program is upgraded based on the target version. For example, when the program libxml has two upgradeable versions, 2.5.0 and 2.6.0, the dependencies between the version program libxml and other programs to be upgraded currently need to be traversed. Before traversing to the upgrade program Apache, libxml needs to be The version of libxml is upgraded to 2.5.0 or higher, and the version of libxml needs to be upgraded to 2.6.0 or higher before upgrading the program PHP, then the minimum number of upgrades will be used as a guideline from multiple upgradeable versions of the same program. The version determines version 2.6.0 as the current target version of libxml to take into account the upgrade of PHP5.5.8 and Apache software, and then upgrade libxml based on version 2.6.0.

Optionally, each upgrade template further includes: at least one risk index, wherein the above risk index is used to quantify the potential risk of the upgrade scheme included in the corresponding upgrade template being executed in at least one application system, and the above risk index is related to the potential risk. The risk is positively correlated, that is, the greater the above-mentioned risk index, the greater the current risk of upgrading based on the corresponding upgrade plan. Specifically, the above hazard index can be assigned according to the experience of the engineer, or determined in advance by performing an upgrade experiment on the virtual machine, or the above hazard index can also be derived from a known statistical model (such as a normal distribution model, etc.), here Not limited. Among them, the risk index of the same upgrade template in different application systems may be different. , is not the focus of this patent discussion. In step 103, if two or more upgrade templates that match the above system information and are related to the same program are found, then the same program in the above application system is updated according to the upgrade template with the lowest risk index among the two or more upgrade templates. Carry out the upgrade process, that is, if two or more upgrade templates matching the above system information are found, and the upgrade programs contained in the two or more upgrade templates are the same, then, from these two or more upgrade templates , select the upgrade template with the lowest risk index to upgrade the program in the above application system.

Optionally, if an upgrade template matching the above system information is found, the found upgrade template and the corresponding risk index can also be output, so that relevant personnel can filter the found upgrade template and determine whether it is based on the found upgrade template. An upgrade process is performed, and when an upgrade determination instruction is received, the upgrade process is performed based on the found upgrade template or the selected upgrade template under the instruction of the upgrade instruction.

Further, if an upgrade template matching the above-mentioned system information cannot be found in step 102, a corresponding upgrade template can be automatically generated and the generated upgrade template can be stored in the above-mentioned template database for subsequent reuse. Specifically, the upgrade control method in the embodiment of the present invention may further include: determining the dependencies between the programs to be upgraded in the application system; The upgrade scheme related to the program to be upgraded in the application system; the generated upgrade scheme is stored in the form of an upgrade template, so that the stored upgrade scheme can be called later.

Of course, in other embodiments, when no upgrade template matching the above-mentioned system information is found in step 102, prompt information may also be output to prompt relevant personnel to intervene in processing.

It should be noted that the upgrade control method in this embodiment of the present invention may be implemented by an upgrade control device, and the upgrade control device may be an independent device, or may be integrated in, for example, a migration management device (for example, a migration management server), which is not described here. limited.

It should be understood that the size of the sequence numbers of the steps in the above embodiments does not mean the sequence of execution, and the execution sequence of each process should be determined by its functions and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

As can be seen from the above, in the embodiment of the present invention, a program-related upgrade scheme is preset, and for the application system to be migrated, the system information of the application system is obtained, and based on the system information, a preset template database is searched for the system related to the system.
