Based on the defects, the embodiment of the invention provides a method for modifying database instance parameters, which comprises the steps of receiving a database instance parameter modification task, determining the operable parameters in the database instance of the parameters to be modified, and modifying the operable parameters of the database instance according to the parameter modification task.
The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
It should be noted that the execution subject of the following method embodiments may be a modification device of the database instance parameters, and the device may be implemented as part or all of the terminal device by software, hardware, or a combination of software and hardware. The execution subjects of the method embodiments described below are described taking a computer device as an example.
Fig. 1 is a schematic flow chart of a method for modifying parameters of an example database according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step S101, determining a database instance parameter modification task, wherein the parameter modification task comprises a database instance of a parameter to be modified, and the parameter modification task is configured into an immediate execution mode or a timing execution mode.
Specifically, a database instance can be managed through a thinkDB platform, the database instance comprises information such as physical ip, an instance name, a port and a database version, the thinkDB is a perception database system, and is a database system which is based on a real-time database technology and an innovative data model theory and faces to the information perception requirements of scattered, multivariate and dynamic sensors and equipment and can manage data; optionally, the parameter modification task may be configured to be in a timing execution mode or an immediate execution mode according to a service requirement, where the timing execution mode is to execute the parameter modification task at a target time point.
The parameter modification task can be a database instance, a parameter and a parameter target value which are modified on line by a user based on a webpage end, wherein the database instance comprises a database instance of the parameter to be modified, the parameter is a standard parameter in the database, and the parameter target value is a value after the parameter is modified.
It should be noted that, assuming that there are 100 database instances that need operation and maintenance, the information of the 100 database instances may be managed through the ThinkDB platform, and the operation and maintenance personnel may select the database instance of the parameter to be modified on the operation interface according to the managed instance information and the service requirement, so as to form a task of modifying the parameter.
Optionally, the ThinkDB platform may include modules such as a point table management module, a real-time query module, a history query module, a data subscription module, and an alarm management module, where the point table management module may sense a management function of a data list in the database, and the management function includes addition, modification, deletion, list import, list export, and the like of the list, the real-time query module may query real-time data in a plurality of lists, the history query module may query history data in each list, the data subscription module is a change of real-time monitoring data, the alarm management module may set an alarm threshold for corresponding data, and alarm information is generated when the data exceeds the threshold. The thindb platform may obtain the database instance list in the parameter modification task through the point table management module, select the database instance of the parameter to be modified through the modules such as real-time query and historical query, determine the parameter in the database instance to be modified, modify the parameter into the parameter target value, and automatically alarm and prompt when the parameter target value exceeds the threshold value through the alarm management module, thereby accurately modifying the parameter of the database instance.
Optionally, the parameter modification task may include different database types and database versions.
And step S102, determining the parameters meeting the verification rules as operable parameters in the database examples of the parameters to be modified.
Specifically, a check rule may be set according to the type of the database and the version of the database, and a parameter that meets the check rule is determined as an operable parameter in the database instance of the parameter to be modified. The database type can be mysql database or oracle database, the same type of database may correspond to different versions of the database, and different types of databases and versions of the database may correspond to different check rules.
For example, the check rule may include a parameter type, wherein the check rule may be formed by setting a parameter type value, determining a parameter with a parameter type value of 1 as an operable parameter in the database instance, and taking a parameter with a parameter type value of 0 as an inoperable parameter, for example, the parameter type value may be set to 1 for a mysql database with a version of 5.7, and the parameter type value may be set to 0 for a mysql database with a version of 8.0, that is, a parameter representing a mysql database with a version of 5.7 may be determined as an operable parameter.
It should be noted that, by setting the check rule, the operation and maintenance personnel can only operate the operable parameters opened by the administrator, and misoperation of other parameters is avoided, so that standardized processing of operation and maintenance operation is realized, and security of database instance parameter modification is ensured.
And S103, modifying the operable parameters of the database instance into parameter target values according to the parameter modification tasks meeting the verification rules.
Specifically, after a parameter modification task is received, whether an instance in the parameter modification task passes verification can be judged, and after the instance passes verification, parameter modification is performed by calling an automated operation and maintenance tool, wherein the automation tool is developed based on Python, the advantages of a plurality of operation and maintenance tools are integrated, functions of batch system configuration, batch program deployment, batch execution commands and the like can be realized.
It should be noted that, before executing the parameter modification task, it may be determined that the parameter modification task is executed immediately or at regular time, and when the parameter modification task is executed immediately, the parameter in the database instance is modified directly by calling ansable according to the database type and the database version and modifying the parameter in the database instance to a parameter target value according to the parameter modification task; when the above-mentioned parameter modification task is executed periodically, the following steps shown in fig. 2 may be executed:
step S201, determining the timing execution time of the parameter modification task.
And step S202, scheduling the parameter modification task through a task scheduler according to the timing execution time.
Specifically, when the service requirement indicates that the parameter modification task needs to be executed at a certain time, that is, the timing execution time of the parameter modification task may be determined first, and when the device detects that the timing execution time has been reached, the parameter modification task is scheduled to the automation operation and maintenance tool through a task scheduler, so that the automation operation and maintenance tool executes the parameter modification task at a fixed time, where the task scheduler may be a Quartz framework.
It should be noted that the parameter modification task may be a timed execution time edited by an operation and maintenance worker on an operation interface of a web page, and the user may set to immediately execute the parameter modification task or execute the parameter modification task at a timed time by a user-defined setting.
According to the method for modifying the database instance parameters, the database instance parameter modification task is received, the parameter modification task is executed immediately or at regular time, the operable parameters in the database instance of the parameters to be modified are determined, and the operable parameters of the database instance are modified according to the parameter modification task.
Fig. 3 is a flowchart illustrating a method for determining whether an instance in a parameter modification task passes verification according to an embodiment of the present invention. As shown in fig. 3, the method includes:
s301, determining a current unverified example in the parameter modification task;

step S302, judging whether the current unverified example is locked or not;
if the operation is locked, continuing to execute the step S301, determining the next unverified instance from the parameter modification task, and controlling to enter the next specified operation;
if not, executing step S303, and judging whether the unverified instance information is correct;
if the instance information is correct, executing the step S304, checking to pass and locking the current unverified instance;
if the instance information is not correct, the step S301 is continued, the next unverified instance is determined from the parameter modification task, and the next specified operation is controlled to be executed.
Specifically, after the parameter modification task is obtained, a current unverified instance can be determined, and whether the current unverified instance is locked or not is judged, that is, whether the current unverified instance is operated by other functions of thindb or not is judged, the other functions can be functions of reconstruction, addition and the like, if the current unverified instance is judged to be unlocked or not, that is, not operated by other functions, whether the current unverified instance information is correct or not is further judged, that is, information such as a maintained physical ip address, port information and whether the instance is correctly connected or not is detected; if the current unverified instance is locked, the next unverified instance is determined to be the current unverified instance from the parameter modification task.
Further, when the information of the current unverified example is judged to be correct, the current unverified example is indicated to pass the verification, and the current unverified example is locked; and when the information of the current unverified example is judged to be incorrect, continuously determining the next unverified example as the current unverified example from the parameter modification task, and further verifying.
It should be noted that, after the instance passes the verification and is locked, the automatic operation and maintenance tool is called to modify the parameters, wherein, according to the type of the database, the parameters of the database can be modified to be the target parameter values by calling different processing scripts.
In the process of modifying the parameter, the parameter type of the operable parameter may be determined first, and optionally, the parameter type may be determined by a parameter type value, for example, a parameter type value of 1 indicates a static parameter, and a parameter type value of 0 indicates a dynamic parameter; if the operable parameters comprise static parameters, the file values are required to be modified and the database is restarted, wherein the file values can be address tables; when the operable parameters only comprise dynamic parameters, only the memory value and the file value need to be modified, the modification result is determined, whether the modification is successful or not can be returned and displayed on a corresponding interface, and the instance can be unlocked after the modification result is returned.
According to the method for modifying the database instance parameters, whether the current unverified instance is locked or not and whether the instance information is correct or not are judged, so that the instance is guaranteed not to be operated by other functions of the Th i nkDB, parameter modification of multiple instances can be processed in batch, the risk of parameter misoperation is avoided, normalized operation and maintenance data management is achieved, and the working efficiency is further improved.
It should be noted that while the operations of the method of the present invention are depicted in the drawings in a particular order, this does not require or imply that the operations must be performed in this particular order, or that all of the illustrated operations must be performed, to achieve desirable results. Rather, the steps depicted in the flowcharts may change the order of execution. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions.
