[0002] With the continuous development of Internet technology, the big data era has arrived, and it has become very important to perform real-time data synchronization. The data synchronization server supports synchronizing data sources in the database to data storage devices such as a search engine (ElasticSearch, ES) to achieve data synchronization.

[0003] Currently, when the data synchronization server performs data synchronization, it is usually configured with multiple data synchronization services. Among them, each data synchronization service corresponds to at least one data synchronization instance, so as to control the corresponding data synchronization instance to run through the data synchronization service, and thus perform data synchronization through the data synchronization instance.

[0056] Figure 5 is a schematic structural diagram of an electronic device provided by this application.

[0057] Through the above-mentioned drawings, specific embodiments of this application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0058] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Here, A and B can be singular or plural. In the written description of the present application, the character " / " generally represents an "or" relationship between the front and back associated objects.

[0060] The technical solution provided by the present application can be applied to the scenario of data synchronization. The data synchronization server supports synchronizing the data source in the database to a data storage such as a search engine (ElasticSearch, ES) to achieve data synchronization. Currently, when the data synchronization server performs data synchronization, it is usually configured with multiple data synchronization services. Among them, each data synchronization service corresponds to at least one data synchronization instance, and the corresponding data synchronization instance is controlled to run through the data synchronization service, so as to perform data synchronization through the data synchronization instance. Among them, the database can include a Mysql database, a Sqlserver database, or a Sqlite database, etc., and the data storage can include a search engine data storage, a Kafka data storage, or an Hbase data storage, etc.

[0061] Currently, in the process of controlling the corresponding data synchronization instance to run through the data synchronization service to perform data synchronization, when the status of the data synchronization service is abnormal, other data synchronization services in the data synchronization server adopt a preemption mode to preempt the data synchronization instance corresponding to the abnormal status data synchronization service and control it to run the data synchronization instance corresponding to the abnormal status data synchronization service; or, when the status of the data synchronization instance is abnormal, other data synchronization services in the data synchronization server adopt a preemption mode to preempt the abnormal status data synchronization instance and control it to run the abnormal status data synchronization instance.

[0062] However, adopting the above-mentioned preemption mode will result in a poor exception handling effect. For example, if the data synchronization service that successfully preempts using the preemption mode has a large number of currently corresponding controlled data synchronization instances, it will affect the operation of the data synchronization instance in the abnormal status, resulting in a poor exception handling effect.

[0063] Therefore, in order to effectively solve the exception problem, when processing the data synchronization instances corresponding to the data synchronization services in an abnormal state, or the data synchronization instances in an abnormal state, in order to improve the exception handling effect, the number of data synchronization instances corresponding to each data synchronization service can be considered, and one of the data synchronization services can be selected, which can be denoted as the target data synchronization service, and used to control the data synchronization instances corresponding to the data synchronization services in an abnormal state, or the data synchronization instances in an abnormal state, so as to effectively solve the exception problem.

[0064] Based on the above technical concept, the present application provides an exception handling method. Next, the implementation process of the exception handling method provided by the present application will be described in detail in combination with specific application scenarios. It can be understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0065] Figure 1 FIG. is a schematic flowchart of an exception handling method provided by the present application. The exception handling method can be executed by a software device and / or a hardware device. The hardware device can be an exception handling device. For example, please refer to Figure 1 As shown, the exception handling method can include:

[0066] S101. Detect the current states of each data synchronization service and the data synchronization instances corresponding to each data synchronization service.

[0067] Among them, the number of data synchronization instances corresponding to each data synchronization service can be the same or different, and can be specifically set according to actual needs. Here, the present application does not limit the number of data synchronization instances corresponding to each data synchronization service.

[0068] For example, the data synchronization service can be a Canal aggregation program, or other data synchronization services, such as a data transfer service program (Digital Theatre System, DTS), etc., and can be specifically set according to actual needs. When the data synchronization service is a Canal aggregation program, the data synchronization instance is a Canal tool, and the corresponding Canal tool is controlled by the Canal aggregation program to achieve data synchronization. The present application takes the Canal aggregation program and its corresponding Canal tool as an example for illustration, but does not mean that the present application is only limited thereto.

[0069] Taking the Canal aggregator for the data synchronization service as an example, for each Canal aggregator for the data synchronization service, the Canal aggregator and its corresponding at least one data synchronization instance can be registered in the registration server; correspondingly, the registration server will create respective nodes for the Canal aggregator and its corresponding at least one data synchronization instance, and monitor the respective states of the Canal aggregator and its corresponding at least one data synchronization instance. By way of example, the registration server is a Zookeeper registration server, which can be referred to Figure 2 as shown Figure 2 is a schematic diagram of a data synchronization server and a registration server provided by this application. Combining Figure 2 it can be seen that assuming there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3, and data synchronization service 1 corresponds to 1 data synchronization instance 1, data synchronization service 2 corresponds to 2 data synchronization instances, namely data synchronization instance 2 and data synchronization instance 3, and data synchronization service 3 corresponds to 3 data synchronization instances, namely data synchronization instance 1, data synchronization instance 2, and data synchronization instance 3, then these three data synchronization services and their corresponding data synchronization instances will be registered in the registration server; correspondingly, the registration server will create respective nodes for these three data synchronization services and their corresponding six data synchronization instances, that is, a total of 9 nodes will be created.

[0070] By way of example, when detecting the current states of each data synchronization service and the data synchronization instances corresponding to each data synchronization service, the states of each data synchronization service monitored by the registration server and the data synchronization instances corresponding to each data synchronization service can be combined to jointly determine whether there is an abnormality; if an object, such as a data synchronization service and / or a data synchronization instance, is in a running state in the data synchronization server and the node created by the registration server for this object exists, then it is determined that the state of this object is a normal state; in the normal state, the corresponding operations can be continued according to the current state of this object.

[0071] If a target object, such as a data synchronization service and / or a data synchronization instance, is in a running state in the data synchronization server and the node created by the registration server for this object is removed, then it is determined that the state of this object is an abnormal state, and then the following S102 is correspondingly executed:

[0072] S102: If it is detected that the current state of the target object is an abnormal state, then determine the target data synchronization service from other data synchronization services according to the number of data synchronization instances corresponding to each other data synchronization service.

[0073] Among them, the target object includes a data synchronization service and / or a data synchronization instance. Other data synchronization services refer to the other data synchronization services among multiple data synchronization services except the data synchronization service indicated by the target object. When the target object is a data synchronization service, the data synchronization service it indicates is the data synchronization service itself. When the target object is a data synchronization instance, the data synchronization service it indicates is the data synchronization service corresponding to the data synchronization instance.

[0074] Exemplarily, the number of target objects can be one or multiple, and can be specifically set according to actual needs. It can be understood that when the number of target objects is multiple, the corresponding processing method is similar to that when the number of target objects is one. Here, this application will take the number of target objects being multiple as an example for illustration, but it does not mean that this application is only limited to this.

[0075] Exemplarily, when determining the target data synchronization service from other data synchronization services according to the number of data synchronization instances corresponding to each of the other data synchronization services, the data synchronization service with the least number of corresponding data synchronization instances can be determined from other data synchronization services according to the number of data synchronization instances corresponding to each of the other data synchronization services; and the data synchronization service with the least number of corresponding data synchronization instances is determined as the target data synchronization service. In this way, by subsequently running the data synchronization instance indicated by the target object through the target data synchronization service with the smallest number of running data synchronization instances, not only can the load of other data synchronization services be balanced, but also the running efficiency of the data synchronization instance indicated by the target object can be improved.

[0076] It can be understood that when determining the target data synchronization service from other data synchronization services according to the number of data synchronization instances corresponding to each of the other data synchronization services, in addition to determining the data synchronization service with the least number of corresponding data synchronization instances as the target data synchronization service, the data synchronization service with the second least number of corresponding data synchronization instances can also be determined as the target data synchronization service, which can be specifically set according to actual needs. Here, this application only takes the data synchronization service with the least number of corresponding data synchronization instances as the target data synchronization service for illustration, but it does not mean that this application is only limited to this.

[0077] For example, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3. Data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. When it is detected that the status of data synchronization service 3 is an abnormal status, then according to the number of data synchronization instances corresponding to data synchronization service 1 and data synchronization service 2 respectively, determine the data synchronization service with the fewest corresponding instances from data synchronization service 1 and data synchronization service 2, that is, data synchronization service 1, and determine data synchronization service 1 as the target data synchronization service.

[0078] For another example, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3. Data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. If the status of one of the data synchronization instances corresponding to data synchronization service 3 is an abnormal status, then according to the number of data synchronization instances corresponding to data synchronization service 1 and data synchronization service 2 respectively, determine data synchronization service 1 with the fewest corresponding instances from data synchronization service 1 and data synchronization service 2, and determine data synchronization service 1 as the target data synchronization service. For the determination methods of the other two data synchronization instances corresponding to data synchronization service 3, they are similar to the above determination method and will not be elaborated here.

[0079] In this way, when the status of the target object is detected to be abnormal, the target data synchronization service can be controlled to run the data synchronization instance indicated by the target object, that is, execute the following S103:

[0080] S103. Control the target data synchronization service to run the data synchronization instance indicated by the target object.

[0081] Exemplarily, when the target object is a data synchronization instance, the data synchronization instance it indicates is the data synchronization instance itself; when the target object is a data synchronization service, the data synchronization instance it indicates is the data synchronization instance corresponding to the data synchronization service.

[0082] For example, when the target object is a data synchronization instance, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3. Data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. If one of the data synchronization instances corresponding to data synchronization service 3 is in an abnormal state, the data synchronization server can determine, according to the number of data synchronization instances corresponding to data synchronization service 1 and data synchronization service 2 respectively, the data synchronization service 1 with the least number of corresponding instances from data synchronization service 1 and data synchronization service 2, and determine data synchronization service 1 as the target data synchronization service. The data synchronization server controls data synchronization service 1 to run the data synchronization instance in the abnormal state.

[0083] For example, when the target object is a data synchronization service, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3, and data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. When it is detected that the state of data synchronization service 3 is abnormal, the data synchronization server can determine, according to the number of data synchronization instances corresponding to data synchronization service 1 and data synchronization service 2 respectively, the data synchronization service 1 with the least number of corresponding instances from data synchronization service 1 and data synchronization service 2, and determine data synchronization service 1 as the target data synchronization service. The data synchronization server controls data synchronization service 1 to run the data synchronization instance corresponding to the data synchronization service in the abnormal state. The control method for the other two data synchronization instances corresponding to data synchronization service 3 is similar to the above control method and will not be elaborated here.

[0084] It can be seen that in this application, during exception handling, the current states of each data synchronization service and its corresponding data synchronization instances can be detected first; if it is detected that the current state of the target object is abnormal, the target data synchronization service can be determined from other data synchronization services according to the number of data synchronization instances corresponding to other data synchronization services respectively; among them, the target object includes a data synchronization service and / or a data synchronization instance, and the target data synchronization service is controlled to run the data synchronization instance indicated by the target object. In this way, the target data synchronization service determined according to the number of data synchronization instances can run the data synchronization instance indicated by the target object in the abnormal state, thus effectively solving the problem of the target object being abnormal.

[0085] Based on the above Figure 1In the illustrated embodiment, in addition to processing abnormal target objects, for the convenience of users to control relevant operations of the data synchronization service and / or data synchronization instance, such as online operations, new operations, or offline operations, in this application, considering that the data synchronization service and / or data synchronization instance are registered in the registration server, the registration server will generate node information corresponding to the data synchronization service and / or data synchronization instance, and relevant operations can be displayed on the web page of data synchronization. In this way, users can touch relevant operations on this web page to control the relevant operations executed by the data synchronization service and / or data synchronization instance, thereby improving the user experience. For example, please refer to Figure 3 as shown Figure 3 is a schematic diagram of a web page for data synchronization provided by this application. It can be seen that Figure 3 it not only includes online operations, new operations, and offline operations of the data synchronization service, but also includes online operations, new operations, and offline operations of the data synchronization instance. Of course, it can also be other operations, such as query operations and log viewing operations of the data synchronization service and / or data synchronization instance.

[0086] For example, when a user performs a click operation on the web page of data synchronization, in response to this touch operation of the user, determine the operation type of the object targeted by the touch operation, where the object includes the data synchronization service and / or data synchronization instance; then, according to the operation type, perform a corresponding control operation on the target object. In this way, users can directly control the object through the control operation, improving the user experience.

[0087] For example, the touch operation can be a click operation, a swipe operation, or other touch operations, which can be specifically set according to actual needs. Here, this application will take the click operation as an example for illustration, but it does not mean that this application is only limited to this.

[0088] For example, when the object of the user's touch operation is a data synchronization instance, the operation types for the data synchronization instance can include at least three operations: the online operation of the data synchronization instance, the new operation of the data synchronization instance, and the offline operation of the data synchronization instance. Of course, it can also include other relevant operations of the data synchronization instance, which can be specifically set according to actual needs. Here, this application will take these three operations as an example for illustration, but it does not mean that this application is only limited to this.

[0089] For example, when the object of the user's touch operation is the first idle data synchronization instance among the data synchronization instances corresponding to multiple data synchronization services, and the touch operation is the online operation of the first idle data synchronization instance, the data synchronization service corresponding to the first idle data synchronization instance can be determined first. Here, the data synchronization service corresponding to the first idle data synchronization instance can be understood as the data synchronization service corresponding to the first idle data synchronization instance during registration, and the data synchronization service corresponding to the first idle data synchronization instance is controlled to run the first idle data synchronization instance, so that the first idle data synchronization instance can be controlled to go online.

[0090] For example, assume that there are three data synchronization services in the data synchronization server, namely Data Synchronization Service 1, Data Synchronization Service 2, and Data Synchronization Service 3. Data Synchronization Service 1 corresponds to 1 data synchronization instance, Data Synchronization Service 2 corresponds to 2 data synchronization instances, and Data Synchronization Service 3 corresponds to 3 data synchronization instances. If one of the data synchronization instances 2-1 corresponding to Data Synchronization Service 2 is in an idle state, then this data synchronization instance 2-1 is recorded as the first idle data synchronization instance. When the touch operation is the online operation of this data synchronization instance 2-1, the data synchronization server can control Data Synchronization Service 1, Data Synchronization Service 2, and Data Synchronization Service 3 to respectively determine whether the online data synchronization instance 2-1 is the data synchronization instance corresponding to it. When it is determined that the data synchronization instance 2-1 is the corresponding service, the data synchronization server controls Data Synchronization Service 2 to run the data synchronization instance 2-1, so as to control the first idle data synchronization instance to perform the online operation.

[0091] For example, after the first idle data synchronization instance goes online, the status of the first idle data synchronization instance can be updated in the registration server correspondingly, and the status of the first idle data synchronization instance is changed to the online status.

[0092] For example, when the object of the user's touch operation is a new data synchronization instance, and the touch operation is the addition operation of the new data synchronization instance, the number of data synchronization instances corresponding to each of the multiple data synchronization services can be determined first, and the data synchronization service corresponding to the least number of data synchronization instances can be determined from the multiple data synchronization services, and the new data synchronization instance is determined as the data synchronization instance corresponding to the data synchronization service with the least number of corresponding data synchronization instances.

[0093] For example, a new data synchronization instance refers to a data synchronization instance whose node information does not exist among the existing data synchronization instance nodes in the registration server currently, then this data synchronization instance is determined as a new data synchronization instance.

[0094] For example, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3. Data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. If there is a new data synchronization instance and the touch operation is an addition operation for this new data synchronization instance, the data server can first determine the number of data synchronization instances corresponding to each of data synchronization service 1, data synchronization service 2, and data synchronization service 3, and determine from the three data synchronization services the data synchronization service with the least number of corresponding data synchronization instances, that is, data synchronization service 1, and determine the new data synchronization instance as the data synchronization instance corresponding to data synchronization service 1.

[0095] Exemplarily, after adding a data synchronization instance, the status of the new data synchronization instance can be updated in the registration server correspondingly, and the status of the new data synchronization instance can be changed to the added status.

[0096] Exemplarily, when the object of the user's touch operation is the second idle data synchronization instance among the data synchronization instances corresponding to multiple data synchronization services and the touch operation is a decommissioning operation for the second idle data synchronization instance, the data synchronization service corresponding to the second idle data synchronization instance can be determined first; here, the data synchronization service corresponding to the second idle data synchronization instance can be understood as the data synchronization service corresponding to the second idle data synchronization instance during registration, and the second idle data synchronization instance can be removed from the data synchronization instances corresponding to the data synchronization service corresponding to the second idle data synchronization instance, so that the second idle data synchronization instance can be controlled to go offline.

[0097] For example, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3. Data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. If one of the data synchronization instances 3-2 corresponding to data synchronization service 3 is in an idle state, then this data synchronization instance 3-2 is recorded as the second idle data synchronization instance. When the touch operation is a decommissioning operation for this data synchronization instance 3-2, the data synchronization server can control data synchronization service 1, data synchronization service 2, and data synchronization service 3 to respectively determine whether the decommissioned data synchronization instance 3-2 is the data synchronization instance corresponding to it. When it is determined that data synchronization service 3 is the data synchronization service corresponding to data synchronization instance 3-2, then data synchronization instance 3-2 is removed from the three instances corresponding to data synchronization service 3, so as to control the second idle data synchronization instance to perform the decommissioning operation.

[0098] Exemplarily, after the second idle data synchronization instance goes offline, the status of the second idle data synchronization instance can be updated correspondingly in the registration server, and the status of the second idle data synchronization instance is updated to the offline status.

[0099] Exemplarily, when the object of the user's touch operation is the data synchronization service, the operation types for the data synchronization service can include at least three operations: the online operation of the data synchronization service, the new operation of the data synchronization service, and the offline operation of the data synchronization service. Of course, it can also include other related operations of the data synchronization service, which can be specifically set according to actual needs. Here, this application takes these three operations as examples for illustration, but it does not mean that this application is only limited to this.

[0100] Exemplarily, when the object of the user's touch operation is the first idle data synchronization service among multiple data synchronization services, and the touch operation is the online operation of the first idle data synchronization service, the data synchronization server can control the first idle data synchronization service to run the data synchronization instance corresponding to the first idle data synchronization service, so as to control the first idle data service to go online.

[0101] For example, assume that there are three data synchronization services in the data synchronization server, namely data synchronization service 1, data synchronization service 2, and data synchronization service 3. Data synchronization service 1 corresponds to 1 data synchronization instance, data synchronization service 2 corresponds to 2 data synchronization instances, and data synchronization service 3 corresponds to 3 data synchronization instances. If data synchronization service 2 is in an idle state, then data synchronization service 2 is recorded as the first idle data synchronization service. When the touch operation is the online operation of data synchronization service 2, the data synchronization server controls data synchronization service 1, data synchronization service 2, and data synchronization service 3 to respectively determine whether the online data synchronization service 2 is itself. When it is determined that it is data synchronization service 2, the data synchronization server controls data synchronization service 2 and runs the data synchronization instance corresponding to data synchronization service 2, so as to control the first idle data synchronization service to perform the online operation.

[0102] Exemplarily, after the first idle data synchronization service goes online, the first idle data synchronization instance service can be updated correspondingly in the registration server to be online, and the status of the first idle data synchronization service is changed to the online status.

[0103] Exemplarily, when the object of the user's touch operation is the new data synchronization service, and the touch operation is the new operation of the new data synchronization service, the data synchronization instance to be allocated can be determined first according to the number of data synchronization instances corresponding to each of the multiple data synchronization services from the data synchronization instances corresponding to each of the multiple data synchronization services; and the data synchronization instance to be allocated is determined as the data synchronization instance corresponding to the new data synchronization service.

[0104] Exemplarily, a new data synchronization service means that when the node information of the data synchronization service does not exist among the existing data synchronization service nodes of the registration server, the data synchronization service is determined to be a new data synchronization service.

[0105] For example, assume that there are three data synchronization services in the data synchronization server, namely Data Synchronization Service 1, Data Synchronization Service 2, and Data Synchronization Service 3, and Data Synchronization Service 1 corresponds to 1 data synchronization instance, Data Synchronization Service 2 corresponds to 2 data synchronization instances, and Data Synchronization Service 3 corresponds to 3 data synchronization instances. Additionally, if there is a new data synchronization service, when the touch operation is an addition operation for the new data synchronization service, the data server can first determine the number of data synchronization instances corresponding to each of Data Synchronization Service 1, Data Synchronization Service 2, and Data Synchronization Service 3, determine one of the data synchronization instances corresponding to Data Synchronization Service 3 as the data synchronization instance to be allocated, and determine one of the data synchronization instances corresponding to Data Synchronization Service 3 as the data synchronization instance corresponding to the new data synchronization service.

[0106] Exemplarily, after adding a new data synchronization service, the status of the new data synchronization instance can be updated correspondingly in the registration server, and the status of the new data synchronization service can be changed to the added status.

[0107] Exemplarily, when the object of the user's touch operation is the second idle data synchronization service among multiple data synchronization services and the touch operation is a decommissioning operation for the second idle data synchronization service, the second idle data synchronization service can be removed from the multiple data synchronization services, and the data synchronization instances corresponding to the second idle data synchronization service can be removed from the data synchronization instances corresponding to the multiple data synchronization services, so as to control the second idle data synchronization service to be decommissioned.

[0108] For example, assume that there are three data synchronization services in the data synchronization server, namely Data Synchronization Service 1, Data Synchronization Service 2, and Data Synchronization Service 3, and Data Synchronization Service 1 corresponds to 1 data synchronization instance, Data Synchronization Service 2 corresponds to 2 data synchronization instances, and Data Synchronization Service 3 corresponds to 3 data synchronization instances. If Data Synchronization Service 3 is in an idle state, then Data Synchronization Service 3 is recorded as the second idle data synchronization service. When the touch operation is a decommissioning operation for Data Synchronization Service 3, the data synchronization server can control Data Synchronization Service 1, Data Synchronization Service 2, and Data Synchronization Service 3 to respectively determine whether the decommissioned Data Synchronization Service 3 is itself. When Data Synchronization Service 3 is determined, Data Synchronization Service 3 is removed. Correspondingly, the data synchronization instances corresponding to Data Synchronization Service 3 are removed, so as to control the second idle data synchronization service to perform a decommissioning operation.

[0109] Exemplarily, after the second idle data synchronization service goes offline, the status of the second idle data synchronization service can be updated in the registration server correspondingly, and the status of the second idle data synchronization service can be changed to the offline status.

[0110] It can be understood that the data synchronization web page provided in this application is only illustrated by taking the six touch operations of the above-mentioned data synchronization service going online, data synchronization service adding, data synchronization service going offline, data synchronization instance going online, data synchronization instance adding, and data synchronization instance going offline as examples, but it does not mean that this application is only limited to this.

[0111] In this way, the user can directly perform touch operations on the data synchronization instance and / or data synchronization service on the data synchronization web page through touch operations, so as to control the relevant operations performed by the data synchronization service and / or data synchronization instance, thereby improving the user experience.
