[0002] With the development of big data and artificial intelligence technologies, a host computer, i.e. a large computer, has high reliability, high availability and high serviceability. In terms of high availability, the host computer has high-availability protection of subsystems, high-availability protection of disks and high-availability protection of sites.

[0055] It is found in the process of implementing the present disclosure that, after decoupling in the process of the high availability of the dual-active site, the switching control end acquires site switching process messages through a complex communication mechanism, but the accuracy of the message return cannot be determined in this process, so the safety and reliability of the switching result cannot be guaranteed, and thus the high availability of the dual-active site cannot be guaranteed.

[0061] Server 105 can be a server that provides various services, such as a backend management server that supports websites browsed by users using terminal devices 101, 102, and 103 (for example only). The backend management server can analyze and process data such as received user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal devices.

[0062] It should be noted that the linkage evaluation method provided by the embodiments of the present disclosure can generally be executed by the server 105. Correspondingly, the linkage evaluation apparatus provided by the embodiments of the present disclosure can generally be arranged in the server 105. The linkage evaluation method provided by the embodiments of the present disclosure can also be executed by a server or a server cluster different from the server 105 and capable of communicating with the terminal devices 101, 102, 103 and / or the server 105. Correspondingly, the linkage evaluation apparatus provided by the embodiments of the present disclosure can also be arranged in a server or a server cluster different from the server 105 and capable of communicating with the terminal devices 101, 102, 103 and / or the server 105.

[0063] The linkage evaluation method provided by the embodiments of the present disclosure can also be executed by the terminal devices 101, 102, 103. Correspondingly, the linkage evaluation apparatus provided by the embodiments of the present disclosure can generally also be arranged in the terminal devices 101, 102, 103. The linkage evaluation method provided by the embodiments of the present disclosure can also be executed by other terminals different from the terminal devices 101, 102, 103. Correspondingly, the linkage evaluation apparatus provided by the embodiments of the present disclosure can also be arranged in other terminals different from the terminal devices 101, 102, 103.

[0064] It should be understood that, Figure 1 The number of terminal devices, networks and servers in the above scenario is only illustrative. According to the implementation needs, there can be any number of terminal devices, networks and servers.

[0065] The linkage evaluation method of the embodiments of the present disclosure will be described in detail below based on the scenario described above. Figure 1 Figures 2 to 5 The linkage evaluation method of the embodiments of the present disclosure will be described in detail below based on the scenario described above.

[0066] Figure 2 A flowchart of the linkage evaluation method according to the embodiments of the present disclosure is schematically shown.

[0067] As shown in Figure 2 The linkage evaluation method 200 of this embodiment includes operations S201-S203.

[0068] In operation S201, in the linkage process between the primary site and the backup site, in the case where it is determined that the primary site has failed, an information configuration table generated by a switching control end and a replication product end is acquired, wherein the switching control end is used to control the replication product end; the replication product end is used to replicate the data generated by the primary site to the backup site; the information configuration table includes first target information generated by the switching control end and second target information generated by the replication product end.

[0069] According to the embodiments of the present disclosure, the first target information can represent the information generated by the switching control end. The second target information can represent the information generated by the replication product end.​

[0070] For example, in a case where it is determined that the primary site fails, the switch control end can send a stop command to the replication product end. The replication product end can receive the stop command sent by the switch control end. The replication product end can send a stop command completion to the switch control end after determining that the stop command has been completed. The switch control end can receive the stop command completion sent by the replication product end. The first target information can represent information corresponding to the sending and receiving of the switch control end. The second target information can represent information corresponding to the receiving and sending of the replication product end.

[0071] In operation S202, the first target information and the second target information are parsed respectively to obtain a first parsing result and a second parsing result.

[0072] According to an embodiment of the present disclosure, the first target information and the second target information can include corresponding time identifiers. The first parsing result and the second parsing result can be obtained by parsing the time identifiers corresponding to the first target information and the second target information respectively. The first parsing result and the second parsing result can respectively represent the parsing results of the time identifiers corresponding to the first target information and the second target information.

[0073] For example, the time identifier can be represented as a time stamp. The time stamp of the first target information can be parsed according to the first target information. If the first target information is information corresponding to the sending and receiving of the switch control end, the time stamp is not a null value. If the first target information is not information corresponding to the sending and receiving of the switch control end, the time stamp is a null value. The time stamp of the second target information can be parsed according to the second target information. If the second target information is information corresponding to the receiving and sending of the replication product end, the time stamp is not a null value. If the second target information is not information corresponding to the receiving and sending of the replication product end, the time stamp is a null value.

[0074] In operation S203, a linkage evaluation result is determined according to the first parsing result and the second parsing result.

[0075] According to an embodiment of the present disclosure, the linkage evaluation result can represent whether the linkage between the switch control end and the replication product end is normal.

[0076] For example, in a case where the first parsing result can represent that the time stamp of the first target information is not a null value and the second parsing result can represent that the time stamp of the second target information is also not a null value, a linkage evaluation result that the linkage between the switch control end and the replication product end is normal can be obtained. In a case where the first parsing result can represent that the time stamp of the first target information is not a null value and the second parsing result can represent that the time stamp of the second target information is a null value, a linkage evaluation result that the linkage between the switch control end and the replication product end is not normal can be obtained.

[0077] According to the embodiment of the present disclosure, in the case that the master site fails, the collected information generated by the switching control end and the replication product end is parsed to obtain a linkage evaluation result, thereby realizing evaluation of the linkage of the switching control end and the replication product end. Through the evaluation of the linkage between the switching control end and the replication product end, the linkage monitoring and checking capability in the host dual-active is improved, effective data and judgment basis are provided for evaluating the dual-active high-availability performance, timely feedback of the dual-active linkage effect is realized, and thus the high-availability guarantee work of the dual-active site is effectively completed.

[0078] It should be noted that the present disclosure considers that the switching control end is a communication hub in the host dual-active system, and the operation behaviors of the control replication product end, the master site and the backup site in the dual-active switching. In the master-backup switching process, the data replication from the master site to the backup site is stopped, which can avoid data loss and production problems caused by dual-active switching, and thus compared with the evaluation of the linkage between the switching control end and the master site or the backup site, the evaluation of the linkage between the switching control end and the dual-active replication product end has more practical application significance.

[0079] Figure 3 A method flowchart for respectively parsing the first target information and the second target information to obtain the first parsing result and the second parsing result according to the embodiment of the present disclosure is schematically shown.

[0080] As shown in Figure 3 The method 300 for respectively parsing the first target information and the second target information to obtain the first parsing result and the second parsing result according to the embodiment can include operation S301 to operation S303.

[0081] In operation S301, a first time identifier of the first target information and a second time identifier of the second target information are respectively extracted.

[0082] According to the embodiment of the present disclosure, the time identifier can represent whether the switching control end or the replication product end has truly generated the target information.

[0083] For example, the switching control end or the replication product end generates the target information, and the time identifier can be a normal time stamp. The switching control end or the replication product end does not generate the target information, and the time identifier can be a time stamp of zero.

[0084] In operation S302, the first parsing result is determined according to the first time identifier.

[0085] According to the embodiment of the present disclosure, the first time identifier can represent whether the switching control end has truly generated the first target information. The first parsing result can represent whether the time stamp of the first target information is normal.

[0086] In operation S303, the second parsing result is determined according to the second time identifier.

[0087] According to embodiments of this disclosure, the second time identifier can characterize whether the copying product has actually generated the second target information. The second parsing result can characterize whether the timestamp of the second target information is normal.

[0088] According to the embodiments of this disclosure, determining the parsing result based on the time identifier of the target information is beneficial for determining whether there is a normal linkage process between the switching control terminal and the copying product terminal.

[0089] Figure 4 The flowchart illustrates a method for determining a linkage evaluation result based on a first analysis result and a second analysis result according to an embodiment of the present disclosure.

[0090] like Figure 4 As shown, the method 400 for determining the linkage evaluation result based on the first analysis result and the second analysis result in this embodiment may include operations S401 to S403.

[0091] In operation S401, if it is determined that the first analysis result indicates that the switching control terminal has abnormal linkage during the linkage process, the first linkage evaluation value is obtained according to the preset initial linkage evaluation value.

[0092] According to embodiments of this disclosure, the preset initial linkage evaluation value can be determined based on actual evaluation needs. If the first analysis result indicates that abnormal linkage occurs at the switching control terminal during the linkage process, the value to be deducted for the abnormal linkage can be subtracted from the preset initial linkage evaluation value to obtain the first linkage evaluation value. The value to be deducted for the abnormal linkage can also be determined based on actual evaluation needs.

[0093] For example, the initial linkage evaluation value can be set to 100, and the value to be deducted in case of abnormal linkage can be set to 20, so the first linkage evaluation value can be 80.

[0094] In operation S402, if it is determined that the second analysis result indicates that abnormal linkage has occurred in the linkage process of the copy product end, the second linkage evaluation value is obtained based on the first linkage evaluation value.

[0095] According to an embodiment of this disclosure, when the second analysis result indicates that abnormal linkage occurs during the linkage process on the copy product side, the value to be deducted for the abnormal linkage can be subtracted from the first linkage evaluation value obtained in operation S401 to obtain the second linkage evaluation value.

[0096] For example, when the first linkage evaluation value obtained in operation S401 is 80, and the value to be deducted in the case of abnormal linkage is 20, the second linkage evaluation value can be 60.

[0097] In operation S403, the linkage evaluation result is determined according to the second linkage evaluation value.

[0098] According to the embodiments of the present disclosure, the linkage evaluation result can be determined according to the second linkage evaluation value obtained in operation S402. The linkage evaluation result can be divided into grades according to the actual linkage evaluation value.

[0099] For example, the grades of the linkage evaluation result can include excellent, good, and poor. The excellent grade can indicate that no abnormal linkage occurs in the linkage process. The good grade can indicate that although abnormal linkage occurs in the linkage process, no exception handling is required. The poor grade can indicate that abnormal linkage occurs in the linkage process, and the abnormal reason needs to be determined and handled. When the second linkage evaluation value obtained in operation S401 is 60, the linkage evaluation result can be determined as poor, and the abnormal reason needs to be determined and handled.

[0100] According to the embodiments of the present disclosure, by analyzing the analysis result, in the case of abnormal linkage, the final linkage evaluation value is determined according to the preset initial linkage evaluation value, and the linkage evaluation result is obtained according to the final linkage evaluation value, which is beneficial to determine the analysis of the abnormal reason in the case of abnormal linkage between the switching control end and the replication product end, and further facilitate the abnormal handling.

[0101] Figure 5 A flowchart of a linkage evaluation method according to another embodiment of the present disclosure is schematically shown.

[0102] As Figure 5 shown, the linkage evaluation method 500 of this embodiment can include operation S501 to operation S505.

[0103] It should be noted that the first target information can include first sub-information and second sub-information; and the second target information can include third sub-information and fourth sub-information.

[0104] In operation S501, the first sub-information generated when the switching control end sends a stop command to the replication product end in the case of determining that the master site fails is obtained.

[0105] According to the embodiment of the present disclosure, the collection script can be deployed on the switching control end and the replication product end of the host end, and information of switching start and end can be configured to control the opening and closing of the collection script. When the information of switching start appears on the switching control end, the collection script deployed on the switching control end is automatically triggered to start execution. When the information of switching end appears on the switching control end, the collection script deployed on the switching control end is automatically triggered to stop execution. The first sub-information generated when the switching control end sends a stop command to the replication product end in the case of determining that the master site has a failure can be obtained by using the collection script. The first sub-information can include a first sub-information text and a time identifier corresponding to the first sub-information. For example, the first sub-information text can be represented as GEO4602I.

[0106] According to the embodiment of the present disclosure, the one-key automatic triggering instruction can effectively improve the linkage checking efficiency of the switching control end and the replication product end in the dual-active switching, and further change the manual experience of the tester to the automatic function.

[0107] In operation S502, third sub-information generated after the replication product end receives the stop command is obtained.

[0108] According to the embodiment of the present disclosure, after the replication product end receives the stop command, the collection script deployed on the replication product end can start execution and obtain the third sub-information. The third sub-information can include a third sub-information text and a time identifier corresponding to the third sub-information. For example, the third sub-information text can be represented as ASN7332I.

[0109] In operation S503, fourth sub-information generated after all replication resource groups of the replication product end complete the stop command is obtained.

[0110] According to the embodiment of the present disclosure, the third target information can be generated after the replication resource groups of the replication product end complete the stop command. The third target information can include a third target information text and a time identifier corresponding to the third target information. The third target information text can be represented as ASN7227I. The collection script deployed on the replication product end can obtain the third target information, and the collection script stops execution until all replication resource groups complete the stop command. The fourth sub-information can include a fourth sub-information text and a time identifier corresponding to the fourth sub-information. For example, the fourth sub-information text can be represented as ASN7109I.

[0111] In operation S504, second sub-information generated after the switching control end receives the completed notification sent by the replication product end is obtained.

[0112] According to the embodiment of the present disclosure, after the second sub-information generated by the monitoring script deployed on the switching control end after obtaining the completion notification sent by the replication product end, the information of switching end can appear on the switching control end, which can automatically trigger the monitoring script deployed on the switching control end to stop execution. The second sub-information can include a second sub-information text and a time identifier corresponding to the second sub-information. For example, the second sub-information text can be represented as GEO1582I.

[0113] It should be noted that the time identifier appearing in operation S501 to operation S504 can be represented by the timestamp when the information text is generated, and the time identifier can be represented as 0 when the information text is not generated.

[0114] In operation S505, the first sub-information, the second sub-information, the third sub-information and the fourth sub-information are stored in the information configuration table.

[0115] According to the embodiment of the present disclosure, the first sub-information, the second sub-information, the third sub-information and the fourth sub-information can be written into the information configuration table. For example, according to the timestamp when the information text is generated, according to the time sequence sorting, there can be GEO4602I≤ASN7332I<ASN7227I<ASN7109I≤GEO1582I.

[0116] According to the embodiment of the present disclosure, by obtaining the linkage information of the switching control end and the dual-active replication product end in the linkage process of the primary site and the backup site, the information configuration table is obtained, and the information generated by the switching control end and the replication product end is separated, which is beneficial to analyze the related linkage information and further evaluate the linkage.

[0117] According to the embodiment of the present disclosure, according to the first analysis result and the second analysis result, the linkage evaluation result is determined, which can also include: in the case that the first analysis result represents that the switching control end does not appear abnormal linkage in the linkage process, and the second analysis result represents that the replication product end does not appear abnormal linkage in the linkage process, according to the preset rule and the preset initial linkage evaluation value, a third linkage evaluation value is obtained; and according to the third linkage evaluation value, the linkage evaluation result is determined.

[0118] According to the embodiment of the present disclosure, the preset rule can be determined according to the timestamp of the target information generated by the switching control end and the replication product end. In the case that neither of the analysis results appears abnormal linkage, it can be determined whether the first target information and the second target information satisfy the preset rule. In the case that the preset rule is not satisfied, the third linkage evaluation value can be obtained by deducting the value required to be deducted in the case that the preset rule is not satisfied on the basis of the preset initial linkage evaluation value. The value required to be deducted in the case that the preset rule is not satisfied can also be determined according to the actual evaluation requirement.

[0119] For example, the preset rule can be a sequence of time for the switching control end and the replication product end to generate target information, such as: first sub-information ≤ second sub-information < third sub-information ≤ fourth sub-information.

[0120] According to the embodiments of the present disclosure, in the case of normal linkage, a final linkage evaluation value is determined according to the preset rule and the preset initial linkage evaluation value, and a linkage evaluation result is obtained according to the linkage evaluation value, thereby further ensuring the credibility of the linkage evaluation result between the switching control end and the replication product end.

[0121] According to the embodiments of the present disclosure, the replication product end includes N replication resource groups, and N is an integer greater than or equal to 2; the information configuration table can further include third target information generated by the replication resource groups in the linkage process and the number of replication resource groups.

[0122] In the case where the third linkage evaluation value matches the preset initial linkage evaluation value, in the case where the number of replication resource groups does not match the N replication resource groups, a fourth linkage evaluation value is obtained according to the third linkage evaluation value; and the linkage evaluation result is determined according to the fourth linkage evaluation value.

[0123] According to the embodiments of the present disclosure, when the third linkage evaluation value is the same as the preset initial linkage evaluation value, it can be determined that the third linkage evaluation value matches the preset initial linkage evaluation value. When the number of replication resource groups is the same as the N replication resource groups, it can be determined that the number of replication resource groups matches the N replication resource groups. When the number of replication resource groups matches the N replication resource groups, it can be determined that, in the linkage process, the third target information is not generated by all the N replication resource groups, and there is a replication resource group that does not complete the stop command.

[0124] According to the embodiments of the present disclosure, the fourth linkage evaluation value can be obtained by deducting a value that needs to be deducted in the case where the number of replication resource groups does not match the N replication resource groups from the third linkage evaluation value.

[0125] For example, the preset initial linkage evaluation value can be 100, the third linkage evaluation value can also be 100, and the value that needs to be deducted in the case where the number of replication resource groups does not match the N replication resource groups can be 20, so the fourth linkage evaluation value can be 80.

[0126] According to the embodiment of the present disclosure, in the case of normal linkage and in the case of meeting the preset rule, the third linkage evaluation value matches the preset initial linkage evaluation value. In the case of normal linkage and in the case of not meeting the preset rule, the linkage evaluation value needs to be determined again to obtain the linkage evaluation result, the linkage evaluation result between the control end and the replication product end is switched more accurately, and the evaluation credibility is improved.

[0127] According to still another embodiment of the present disclosure, the linkage evaluation method can further include:

[0128] According to the information configuration table and the linkage evaluation result, an evaluation result report text is obtained.
