Embodiment one

An 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 the system information of the application system currently to be migrated;

Wherein, the above-mentioned system information includes: information for indicating 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 upgrades, patching, and plug-in updates. 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 program consists of general support software and various application software 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 called a cloud computing operating system or a cloud computing center operating system).

In step 101, by traversing the application system globally, the status of the application system (such as which programs need to be upgraded, the situation of each program on system resources, the dependency relationship between each program, etc.) System information indicating the information of each program to be upgraded in the above application system. Further, the above system information may also include any one or more of the following information: the occupancy of system resources by each program to be upgraded (such as the proportion of system resources occupied by each program to be upgraded), the relationship between each program to be upgraded dependencies. Among them, the dependency between each program determines 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). system) determines that Tomcat cannot be upgraded before MySQL is upgraded. Specifically, the dependencies between 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 above-mentioned system information, search for an upgrade template matching the above-mentioned system information in a preset template database;

Wherein, the template database stores more than two upgrade templates, 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 based on historical experience of application system migration and/or collection and analysis of system information of each application system in advance. 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 corresponding upgrade process of one or more than two programs (such as 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 an upgrade plan related to one or more than two programs, the system information obtained through step 101 can be obtained from the template database Find upgrade templates that match the above systems. For example, according to the information indicating each program to be upgraded included in the system information acquired in step 101, an upgrade template including an upgrade solution related to the corresponding program may be searched from the template database.

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

Further, considering that an application system may contain many programs to be upgraded, the programs with dependencies can be clustered in advance through a clustering algorithm. Specifically, based on the image similarity algorithm and the obtained above-mentioned system information, searching for an upgrade template that matches the above-mentioned system information in the preset template database includes: dividing the graph representing the above-mentioned system information into two or more through a clustering algorithm Subgraphs; for each subgraph, an upgraded template matching each subgraph is searched in a preset template database based on an image similarity algorithm. Wherein, the aforementioned clustering algorithm may be, for example, Min-Cut algorithm, 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, perform upgrade processing on 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 plan related to one or more programs, the upgrade plan can be used to guide the upgrade process of the corresponding one or more programs (for example, when to upgrade, how to upgrade, etc.). Therefore, when an upgrade template matching the above-mentioned system information is found in step 102, the program to be upgraded in the above-mentioned application system can be upgraded accordingly 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 once at most. Specifically, the upgrade control method in the embodiment of the present invention also includes: when there are multiple upgradeable versions of the same program, traversing the dependencies between the same program and other programs currently to be upgraded, so as to minimize the number of upgrades A target version is determined from a plurality of upgradeable versions of the same program as a criterion, and the same program is upgraded based on the target version. For example, when there are two upgradeable versions of the program libxml, 2.5.0 and 2.6.0, the dependencies between the traversal version of the program libxml and other programs currently to be upgraded, if you traverse to the upgrade program Apache, you need to install libxml version to 2.5.0 or higher, and the version of libxml needs to be upgraded to 2.6.0 or higher before the upgrade program PHP, then use the minimum number of upgrades as a guideline to upgrade from multiple upgradeable versions of the same program above 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 risk index is used to quantify the potential risk of the upgrade solution included in the corresponding upgrade template in at least one application system, and the risk index is related to the potential The risks are positively correlated, that is, the greater the above-mentioned risk index, the greater the current risk of upgrading based on the corresponding upgrading scheme. Specifically, the above-mentioned hazard index can be assigned based on the experience of the engineer, or determined in advance through the evaluation after the upgrade experiment on the virtual machine, or the above-mentioned hazard index can also be derived by a known statistical model (such as a normal distribution model, etc.), where Not limited. Wherein, 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 matching the above-mentioned system information and related to the same program are found, the same program in the above-mentioned application system will be updated according to the upgrade template with the lowest risk index among the above-mentioned two or more upgrade templates. Perform upgrade processing, that is, if two or more upgrade templates that match the above system information are found, and the upgrade solutions contained in the two or more upgrade templates target the same program, then, from the two or more upgrade templates Among them, the upgrade template with the lowest risk index is selected to upgrade the programs 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 Perform upgrade processing. When receiving a confirmation upgrade instruction, perform upgrade processing based on the found upgrade template or the selected upgrade template under the instruction of the upgrade instruction.

Further, if no upgrade template matching the above system information is found in step 102, a corresponding upgrade template may be automatically generated and stored in the template database for subsequent reuse. Specifically, the upgrade control method in the embodiment of the present invention may further include: determining the dependencies among the programs to be upgraded in the above-mentioned application system; The upgrade plan related to the program to be upgraded in the application system; the generated upgrade plan is stored in the form of an upgrade template, so that the stored upgrade plan can be called later.

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