[0022] The above embodiments of this disclosure have the following beneficial effects: The task migration method of some embodiments of this disclosure can complete the migration of tasks from servers experiencing errors, reducing task processing time. Specifically, the reason for the long processing time is that tasks from servers experiencing errors cannot run in a timely manner, resulting in a long processing time. Based on this, the task migration method of some embodiments of this disclosure first checks whether there is server information that meets the target conditions in a preset server information table. This allows it to determine whether there is abnormal server information. Then, in response to the existence of abnormal server information, the server information that meets the target conditions is determined as candidate server information, resulting in a candidate server information group. This allows abnormal server information to be filtered out, providing data support for subsequent task migration. Finally, the tasks in the servers corresponding to each candidate server information in the candidate server information group are migrated. Thus, the migration of tasks from servers experiencing errors can be completed, reducing task processing time. Attached Figure Description

[0036] Figure 1 This is a schematic diagram of an application scenario of a task migration method according to some embodiments of the present disclosure.

[0037] exist Figure 1In the application scenario, firstly, the computing device 101 can detect whether there is server information in the preset server information table 102 that meets the target condition 103. Here, the server information table 102 can refer to a list containing information about various servers. Here, server information can refer to server information, including but not limited to at least one of the following: server name, creation time, historical running time, information status, etc. Here, information status can represent the state of the server. For example, server information can be "Server name: Server A; Creation time: 2020-12-29-12:00; Historical running time: 2021-1-28-14:55; Information status: Normal state". Here, the target condition 103 can be: the time interval between the historical running time and the current time included in the server information is greater than or equal to a preset interval. Then, in response to the existence, the computing device 101 can determine the server information that meets the above target condition 103 as candidate server information, obtaining a candidate server information group 104.

No specific limitations are made here.

[0039] It should be understood that Figure 1 The number of computing devices shown is merely illustrative. Any number of computing devices can be used depending on implementation needs.

[0040] Continue to refer to Figure 2 The flowchart 200 illustrates some embodiments of a task migration method according to the present disclosure. The task migration method includes the following steps:

[0041] Step 201: Check if there is server information in the preset server information table that meets the target conditions.

[0042] In some embodiments, firstly, the execution body of the task migration method (e.g. Figure 1The computing device 101 shown can detect whether there is server information that meets the target conditions in a preset server information table. Here, the server information table can refer to a list containing information about various servers. For example, the server information table may include "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Running Time: 2021-1-28-14:55; Information Status: Normal]"; [Server Name: Server B; Creation Time: 2020-12-29-12:00; Historical Running Time: 2021-1-28-14:58; Information Status: Normal]"; [Server Name: Server C; Creation Time: 2020-12-29-12:00; Historical Running Time: 2021-1-28-14:56; Information Status: Normal]". Here, server information can refer to server information, including but not limited to at least one of the following: server name, creation time, historical running time, information status, etc. Here, information status can represent the state of the server. For example, server information could be "Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal". Here, target condition 103 could be: the time interval between the historical run time and the current time included in the server information is greater than or equal to a preset interval. For example, the historical run time included in the server information "Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal" could be "2021-1-28-14:55". The current time could be "2021-1-28-14:59". The preset interval could be "3 minutes". The server information "Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal" includes a historical run time "2021-1-28-14:55" and a current time "2021-1-28-14:59" with a time interval of "4 minutes", which is greater than the preset interval "3 minutes". Therefore, it can be detected that the server information "Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal" meets the target condition.

[0043] Step 202: In response to the existence, server information that meets the above target conditions is identified as candidate server information, thus obtaining a candidate server information group.

[0044] In some embodiments, in response to the existence of such information, the execution entity may determine server information that satisfies the target conditions as candidate server information, thereby obtaining a candidate server information group.

[0045] As an example, the server information table can include "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal]"; [Server Name: Server B; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:58; Information Status: Normal]"; [Server Name: Server C; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:58; Information Status: Normal] ...; [Server Name: Server C; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:58; Information Status: Normal]; [Server Name: Server C; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:58; Information Status: Normal]; [Server Name: Server C; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:58 Server information that meets the above target conditions in "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal Status]" is determined as candidate server information, resulting in the candidate server information group "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal Status]"; [Server Name: Server C; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:56; Information Status: Normal Status]".

[0046] Step 203: Perform migration processing on the tasks in the servers corresponding to each candidate server information included in the above candidate server information group.

[0047] In some embodiments, the execution entity may perform migration processing on the tasks in the servers corresponding to each candidate server information included in the candidate server information group. Here, migration processing may refer to migrating the tasks in the server to other servers. For example, the tasks in server "A" corresponding to the candidate server information "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal Status]" in the candidate server information group "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:56; Information Status: Normal Status]" may be migrated to server "B".

[0048] The above embodiments of this disclosure have the following beneficial effects: The task migration method of some embodiments of this disclosure can complete the migration of tasks from servers experiencing errors, reducing task processing time. Specifically, the reason for the long processing time is that tasks from servers experiencing errors cannot run in a timely manner, resulting in a long processing time. Based on this, the task migration method of some embodiments of this disclosure first checks whether there is server information that meets the target conditions in a preset server information table. This allows it to determine whether there is abnormal server information. Then, in response to the existence of abnormal server information, the server information that meets the target conditions is determined as candidate server information, resulting in a candidate server information group. This allows abnormal server information to be filtered out, providing data support for subsequent task migration. Finally, the tasks in the servers corresponding to each candidate server information in the candidate server information group are migrated. Thus, the migration of tasks from servers experiencing errors can be completed, reducing task processing time.

[0049] Further reference Figure 3 The diagram illustrates flowcharts of some other embodiments of the task migration method according to this disclosure. The task migration method includes the following steps:

[0050] Step 301: Check if there is server information in the preset server information table that meets the target conditions.

[0051] Step 302: In response to the existence, server information that meets the above target conditions is identified as candidate server information, and a candidate server information group is obtained.

[0052] In some embodiments, the specific implementation of steps 301-302 and the resulting technical effects can be found in [reference needed]. Figure 2 Steps 201-202 in the corresponding embodiments will not be repeated here.

[0053] Step 303: Lock the above server information table and determine whether the server information table contains server information corresponding to the local server.

[0054] In some embodiments, the execution body of the task migration method (e.g. Figure 1 The computing device 101 shown can lock the aforementioned server information table and determine whether server information corresponding to the local server exists in the aforementioned server information table. Here, locking can refer to locking processing, used to prevent other servers from tampering with the information. In practice, it can be determined whether server information including the server name corresponding to the local server exists in the server information table. Here, the local server can refer to the aforementioned execution entity.

[0055] Step 304: In response to the confirmation of existence, the tasks in the servers corresponding to the above-mentioned alternative server information are migrated.

[0056] In some embodiments, in response to determining that an alternative server exists, the aforementioned execution entity can perform migration processing on the tasks in the server corresponding to the aforementioned alternative server information through the following steps:

[0057] The first step involves locking the aforementioned candidate server information and determining the running status of the servers corresponding to that candidate server information. Determining the running status of the servers corresponding to the candidate server information is to determine whether the tasks on those servers have been migrated by other servers. Here, running status can represent whether the server is running or not.

[0058] The second step, in response to the aforementioned "not running" status, determines whether the time interval between the historical running time and the current time included in the candidate server information is greater than or equal to a preset interval. In practice, the candidate server information can be "[Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Running Time: 2021-1-28-14:55; Information Status: Normal]". The candidate server information includes the historical running time "2021-1-28-14:55", the current time "2021-1-28-15:00", and the preset interval can be "4 minutes". Therefore, it can be determined that the time interval "5 minutes" between the historical running time and the current time included in the candidate server information is greater than the preset interval "4 minutes".

[0059] The third step, in response to the determination, is to modify the information status of the aforementioned candidate server information to an "downtime" state, and to migrate the tasks in the servers corresponding to the aforementioned candidate server information to the aforementioned local server. Here, the information status can be a state that indicates whether the server is functioning normally.

[0060] In practice, in response to the determination, firstly, the information status [Normal Status] of the above alternative server information [Server Name: Server A; Creation Time: 2020-12-29-12:00; Historical Run Time: 2021-1-28-14:55; Information Status: Normal Status] can be changed to [Downtime Status]. Then, the tasks in the servers corresponding to the above alternative server information can be migrated to the above local server.

[0061] Step 305: In response to the determination that the server does not exist, the server information of the local server is added to the server information table to update the server information table.

[0062] In some embodiments, in response to determining that the server does not exist, the executing entity may add the server information of the local server to the server information table to update the server information table. For example, the server information of the local server may be [Server Name: Server D; Creation Time: 2021-01-25 12:00; Historical Running Time: 2021-01-28 16:55; Information Status: Normal]. The server information of the local server [Server Name: Server D; Creation Time: 2021-01-25 12:00; Historical Running Time: 2021-01-28 16:55; Information Status: Normal] may be added to the server information table to update the server information table.

[0063] from Figure 3 It can be seen that, with Figure 2 Compared to the description of some corresponding embodiments, Figure 3 In some corresponding embodiments, process 300 can determine whether the server has recovered and whether the tasks on the server have been migrated to other servers when handling a downtime server. This demonstrates flexibility in handling downtime servers and improves server availability.

[0064] Further reference Figure 4 The diagram illustrates flowcharts of further embodiments of a task migration method according to the present disclosure. This task migration method includes the following steps:

[0065] Step 401: Check if there is server information in the preset server information table that meets the target conditions.

[0066] Step 402: In response to the existence, server information that meets the above target conditions is identified as candidate server information, and a candidate server information group is obtained.

[0067] Step 403: Perform migration processing on the tasks in the servers corresponding to each candidate server information included in the above candidate server information group.

[0068] In some embodiments, the specific implementation of steps 401-403 and the resulting technical effects can be found in [reference needed]. Figure 2 Steps 201-203 in the corresponding embodiments will not be repeated here.

[0069] Step 404: In response to receiving an execution request for a task in the task table, select a task whose status meets the preset conditions from the task table as a task to be executed, and obtain a task group to be executed.

[0070] In some embodiments, the execution body of the task migration method (e.g. Figure 1The computing device 101 shown can, in response to receiving an execution request for a task in the task table, select tasks whose task status meets preset conditions from the task table as tasks to be executed, thus obtaining a group of tasks to be executed. Here, the task table can be a list containing various tasks. Here, the task table can be a list of tasks and their related information stored on a local server. Here, a task can refer to thread information. Here, the preset condition can be "task status is normal". Here, a task in the task table can include, but is not limited to, at least one of the following: task identifier, task parameters, server name, task status, etc. Here, task parameters are parameters necessary for executing the task. Here, task status can characterize whether a task can be executed normally. For example, a task could be: [Task identifier: abcde; Task parameters: XX, YY; Server name: Server D; Task status: normal].

[0071] As an example, the task table can include {[Task ID: abcde; Task Parameters: XX, YY; Server Name: Server D; Task Status: Normal]; [Task ID: cde; Task Parameters: XX, KK; Server Name: Server D; Task Status: Normal]; [Task ID: abc; Task Parameters: XX, MM; Server Name: Server D; Task Status: Abnormal]}. Tasks whose status meets the preset condition "task status is normal" can be selected from the task table {[task ID: abcde; task parameters: XX, YY; server name: server D; task status: normal]; [task ID: cde; task parameters: XX, KK; server name: server D; task status: normal]; [task ID: abc; task parameters: XX, MM; server name: server D; task status: abnormal]} as tasks to be executed, resulting in the task group to be executed: "{[task ID: abcde; task parameters: XX, YY; server name: server D; task status: normal]; [task ID: cde; task parameters: XX, KK; server name: server D; task status: normal]}".

[0072] Step 405: Based on the task identifier of the task to be executed in the above task to be executed group, perform processing steps for each task to be executed in the above task to be executed group.

[0073] In some embodiments, firstly, the executing entity may identify tasks with the same task identifier in the task group as abnormal tasks. Then, it removes the abnormal tasks from the task group. For each task in the task group after the abnormal tasks have been removed, the following processing steps are performed:

[0074] The first step is to lock and execute the tasks to be executed. In practice, the executing entity can first lock the tasks to be executed. Then, the tasks can be executed. For example, a task to be executed could be [Task ID: abcde; Task Parameters: XX, YY; Server Name: Server D; Task Status: Normal].

[0075] The second step is to re-execute the aforementioned task in response to execution failure. In practice, the executing entity can re-execute the aforementioned task in response to execution failure.

[0076] Step 406: In response to the execution count of the above-mentioned task being greater than or equal to a predetermined threshold, the task status of the above-mentioned task being executed is changed to an abnormal status.

[0077] In some embodiments, the executing entity may change the task status of the task to be executed to an abnormal state in response to the execution count corresponding to the task being executed being greater than or equal to a predetermined threshold. Here, the setting of the predetermined threshold is not limited. In practice, the task status of the task to be executed [task ID: abcde; task parameters: XX, YY; server name: server D; task status: normal state] may be changed from [normal state] to [abnormal state] in response to the execution count corresponding to the task being executed being greater than or equal to the predetermined threshold "3 times".

[0078] Step 407: Issue an early warning for tasks in abnormal states.

[0079] In some embodiments, the aforementioned execution entity may generate abnormal alarm information for tasks in an abnormal state and send it to the task alarm platform for prompt processing.

[0080] Optionally, in response to completion of execution, the aforementioned pending tasks are deleted. In practice, the aforementioned executing entity may delete the aforementioned pending tasks from the task table in response to completion of execution.

[0081] from Figure 4 It can be seen that, with Figure 2 Compared to the description of some corresponding embodiments, Figure 4 In some corresponding embodiments, process 400 can provide an alarm for tasks in abnormal states. This prevents subsequent tasks from being blocked due to task abnormalities, ensuring smooth task processing.

[0082] Further reference Figure 5 As an implementation of the methods shown in the above figures, this disclosure provides some embodiments of a task migration apparatus, which are similar to... Figure 2Corresponding to the method embodiments shown, the device can be specifically applied to various electronic devices.
