[0069] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0070] This specification relates to the operation and maintenance control technology of a dual-active system based on a mainframe (hereinafter referred to as the mainframe dual-active system), which can be applied in the financial field (such as the dual-active system of a bank data center, etc.) or other fields. Since the operation and maintenance under a multi-active system is similar to that under a dual-active system, for those skilled in the art, the operation and maintenance control technology of this specification can also be adapted to a multi-active system based on a mainframe (such as two locations and three centers, etc.).

[0071] Take data centers as an example. The so-called "active-active" or "multi-active" data centers are different from the traditional active-active mode. In the former, two or more data centers are in operation, can run the same applications, have the same data, and can provide cross-center business load balancing operation capabilities to achieve continuous application availability and disaster backup capabilities; the latter (i.e. active-active mode) is that the production center is put into operation and the disaster recovery center is not working. Only when a disaster occurs and the production center is paralyzed, the disaster recovery center is started. The biggest features of the "active-active" data center are: 1. Fully utilize resources to avoid a data center being idle for a long time and causing waste. Through resource integration, the service capacity of the "active-active" data center can be doubled; 2. If one of the data centers in the "active-active" data center fails, the business of the failed data center can be quickly switched to another running data center, and the switching process is imperceptible to users.

[0072] refer to Figure 2As shown, the host active-active system of some embodiments of the present specification may include an operation and maintenance device 10, a first center 20a and a second center 20b; the operation and maintenance device 10 can be used to perform operation and maintenance control (such as information display, active-active switching, system update, etc.) on the first center 20a and the second center 20b. The first center 20a and the second center 20b serve as both production centers and disaster recovery centers. As production centers, the first center 20a and the second center 20b can both provide services to the outside world and generate data; of course, according to actual needs, the tasks of the first center 20a and the second center 20b can be the same or different; as disaster recovery centers, the first center 20a and the second center 20b can back up each other and ensure data consistency through real-time synchronization.

[0073] The present specification provides an operation and maintenance method for a host active-active system that can be applied to an operation and maintenance device. Figure 3 As shown, in some embodiments, the operation and maintenance method of the host active-active system may include the following steps:

[0074] S301: Receive a call instruction for a target operation and maintenance interface.

[0075] S302: Call a JCL (Job Control Language) job generation script according to the calling instruction to generate a JCL job.

[0076] S303: Submit the JCL job to the host operating system for processing.

[0077] S304: Obtain the processing result of the JCL job from the host operating system.

[0078] In the embodiments of the present specification, when the operation and maintenance device receives a call instruction for the target operation and maintenance operation interface, it can call the JCL job generation script to automatically generate a JCL job, automatically submit it to the host operating system for processing, and automatically obtain the processing result of the JCL job from the host operating system, thereby eliminating or greatly reducing the complicated steps of command input, result interpretation, etc. for the operation and maintenance personnel, thereby greatly improving the operation and maintenance timeliness of the host active-active system and lowering the operation and maintenance threshold.

[0079] The operation and maintenance device side may be configured with a main program written in a mainframe-based programming language, and when the main program is executed, the operation and maintenance method of the mainframe active-active system of the embodiment of this specification may be implemented. For example, in some embodiments, the mainframe-based programming language may be, for example, REXX (Restructured Extended Executor) language, COBOL (Common Business-Oriented Language) language, etc.

[0080] In some embodiments, some operation and maintenance operation interfaces may be preset and exposed to the user end. Each operation and maintenance operation interface may be used to implement the issuance of corresponding operation and maintenance commands. Accordingly, the call instruction may be a selection operation for the operation and maintenance operation interface. In this way, the operation and maintenance personnel do not need to manually input specific operation and maintenance commands, but can implement the issuance of corresponding operation and maintenance commands by selecting the operation and maintenance operation interface, thereby greatly reducing the complexity of user operations.

[0081] In some embodiments, the operation and maintenance operation interface may include operation interface options such as information display, active-active switching, and system update. The operation and maintenance device may display these operation interface options on a user interface to facilitate user selection as needed. Among them, the timing for the operation and maintenance device to display the operation interface may be an active display after the operation and maintenance device is initialized, or it may be a passive display of the operation and maintenance device in response to user instructions. Each operation and maintenance operation interface may have a single-layer or multi-layer structure. When the operation interface adopts a multi-layer structure, modifying the code of any layer will basically not affect the changes in the code of other layers in the operation interface, which facilitates subsequent expansion, updating, and maintenance.

[0082] In some embodiments, receiving a call instruction for a target operation and maintenance operation interface may include: after providing a user interface including operation and maintenance operation interface options to a user terminal, receiving a selection operation of the user terminal for the operation and maintenance operation interface options. Wherein, the selected operation and maintenance operation interface is the target operation and maintenance operation interface. In some embodiments, the operation and maintenance operation interface options can be represented by a single character, such as a status query interface represented by a single character, a switching interface represented by a single character, etc. When a user enters a target operation and maintenance operation interface represented by a single character at a designated location in the user interface, it is equivalent to the user issuing a call instruction for the operation and maintenance operation interface corresponding to the single character.

[0083] For example, in Figure 4a In the exemplary embodiment shown, a user interface is displayed through the user terminal, in which: "LIFELINE CHECK&SWITCH TOOL" represents the lifeline check and switch tool, "PLS CHOOSE THE FUNCTION" represents please select the operation and maintenance interface class (each operation and maintenance interface class may include one or more options), "FUNCTION: D ”, indicating that the user has selected the display category “D”, “D=DISPLAY” indicates the display category, and “S=SWITCH” indicates the display switch category. When the user selects the display category “D”, the user interface can jump to the following Figure 4b The user interface shown.

[0084] exist Figure 4bIn the user interface shown, “LIFELINE DISPLAY&CHECK” means lifeline display and check, “PLS CHOOSE THE DETAIL FUNCTION” means please select a specific display item, and “FUNCTION SELECTION: 5 ", indicating that the user has selected display item "5", "1=WORKLOAD(DISPLAY&CHECK)" indicates that display item "1" is transaction routing (display and check), "2=WKL STATUS CHECK FOR SWITCH" indicates that display item "2" is checking transaction routing status for the purpose of switching, "3=ADVISOR(INCLUDING AGENT&LB CONNECTION STATUS)" indicates that display item "3" is address space status (including connection status between agent and LB), "4=LB" indicates that display item "4" is load balancer (Load Balancer, LB), and "5=WKL STATUS ON BOTH SITE" indicates that display item "5" is transaction routing status of both parties (for example, the first center and the second center).

[0085] Transaction routing (WORKLOAD) is used to control which site (for example, the first center or the second center) the transaction is sent to. That is, in the host active-active system, active-active switching can be performed by switching the transaction routing direction. The transaction routing status can include three types: stop status (deactivate), working status (activate), and quiet status (quiesce). Among them, the stop status means that the transaction routing destination site stops the execution of the current connection (that is, the current task) and does not receive new connections (that is, new tasks); the working status means that the transaction routing destination site executes the current connection normally and can receive new connections during the execution process (or after execution); the quiet status means that the transaction routing destination site does not receive new connections, but the current connection will be completed. When switching the transaction route, it can be done in the order of activate→quiesce→deactivate→activate. For example, in one embodiment, if a failure occurs in the first center 20a, the activate state of the transaction route of the first center 20a can be switched to the quiesce state so that the first center 20a can complete the currently processed connection; then the quiesce state is switched to the deactivate state; and finally, the second center 20b switches the transaction route with the same name from the deactivate state to the activate state.

[0086] In other embodiments, receiving a call instruction for a target operation and maintenance operation interface may also include: receiving a call instruction for a target operation and maintenance operation interface sent by a job calling program. In some embodiments, the job calling program may also be written based on the REXX language. The job calling program is mainly used to automatically issue call instructions to the main program of the operation and maintenance device in a timely manner, without the need for the user to select the operation and maintenance operation interface option, which can help to further improve the operation and maintenance timeliness of the host active-active system. Therefore, the job calling program is particularly suitable for batch job task scenarios. In some embodiments, the above-mentioned timeliness can be pre-specified as needed during programming. For example, in some embodiments, the above-mentioned timeliness can be scheduled (for example, at the end of each day, etc.).

[0087] In some embodiments, JCL job templates corresponding to various scheduling instructions can be pre-configured to form a JCL job template set accordingly; and a JCL job generation script can also be written in advance based on REXX language or COBOL language, etc.; when a call instruction is received, the JCL job generation script can be called according to the call instruction, so that the JCL job can be automatically generated.

[0088] It should be understood that the JCL jobs mentioned in the embodiments of this specification are only exemplary; the adapted computer languages ​​may be different for host active-active systems of different equipment manufacturers and / or different host models; therefore, in some other embodiments, any other computer language suitable for the host active-active system may be selected to write job tasks as needed.

[0089] In some embodiments, the JCL job generation script generates a JCL job in the following manner:

[0090] 1) From the JCL job template set, search for a JCL job template that matches the call instruction. Each JCL job template in the JCL job template set may correspond to a specific job item, and each specific job item has a unique command identifier (e.g. Figure 4b In the specific display items shown in , “1” to “5” correspond to five call instructions respectively); thus, the corresponding JCL job template can be matched from the JCL job template set through this correspondence.

[0091] 2) Modify the JCL job template according to the specified parameters in the calling instruction to obtain the corresponding JCL job.

[0092] Each JCL job template can provide the basic structure and content of the corresponding job task. Some values ​​that need to be replaced or changed can be left blank or given a default value of 0. When a JCL job template corresponding to a call instruction is matched, the specified parameters carried by the call instruction are filled in with the blank items in the template or directly replaced with the default values ​​in the template, thereby completing the steps of automatically generating a JCL job from a JCL job template.

[0093] In the embodiment of this specification, each JCL job template should contain three JCL basic statements:

[0094] (1) Job statement (JOB): identifies the start of a job and provides necessary operating parameters. That is, the JOB statement marks the start of a job, assigns a job name, and sets related positional parameters and keyword parameters. The first statement of each JCL job must be a JOB statement. In an exemplary embodiment, the format of the JOB statement can be as follows:

[0095] / / Job name JOB position parameters [, keyword parameters] [, keyword parameters] ... [comments]

[0096] (2) Execute statement (EXEC): Identifies the start of a job step and defines the program or process to be executed in this job step. That is, the EXEC statement marks the start of each job step in the JCL job and tells the system how to execute the job step. In an exemplary embodiment, the EXEC statement format can be as follows:

[0097] / / [Job step name] EXEC positional parameters [, keyword parameters] ... [symbol parameter = value] ... [comment]

[0098] (3) Data definition statement (DD): used to describe the data files required by the application. That is, the data definition statement is used to define a data set and the input and output resources required by the data set. In an exemplary embodiment, the format of the DD statement can be as follows:

[0099] / / [DD name]DD[positional parameters][, keyword parameters]…[comments]

[0100] In some embodiments, in the above JCL statements, positional parameters are parameters that maintain relative positions with other parameters. When calling a function, parameters can be passed according to the parameter positions defined in the function. Keyword parameters consist of a keyword and variable data after the equal sign. For some functions with multiple parameters, if you want to specify only one or some of the parameters, you can assign parameters to them through keyword parameters. If there are both positional parameters and keyword parameters in a statement, all keyword parameters must be located after the positional parameters.

[0101] In addition to the above JCL basic statements, the JCL job can also add other statements as needed. For example, in some embodiments, the JCL job can also add any one or more of the following six additional statements as needed:

[0102] 1) / * statement: indicates the end of the data in the stream or calls the JES control statement;

[0103] 2) / / * Statement: comment statement, write the comment content from the 4th to the 80th column;

[0104] 3) / / Statement: empty statement, used to mark the end of a job;

[0105] 4) PROC statement: the start marker of an in-stream procedure (IN-STREAM PROCEDURE) or a cataloged procedure (CATALOGED PROCEDURE).

[0106] 5) PEND statement: marks the end of a process within a stream.

[0107] 6) Command statement: The operator uses this statement to write the operation command in the input stream.

[0108] When a user needs to use the host operating system to complete a relatively complex job task (such as system upgrade, etc.), a job flow can be prepared, which includes one or more jobs and their dependencies, and can also include the expected return value of each job, etc. Therefore, in some embodiments, before submitting the JCL job to the host operating system for processing, the host active-active system operation and maintenance method also includes the following:

[0109] 1) Provide the JCL job to the scheduling tool for processing.

[0110] The scheduling tool is an automated scheduling tool that can integrate multiple JCL jobs into a JCL job stream (JobStream). The JCL job stream can be executed on a scheduled basis. When the JCL job stream runs, the jobs will be executed in a pre-set order. When a job returns an exception, the execution of the JCL job stream can be interrupted and the user can confirm. For example, in some embodiments, the TWS (Tivoli Workload Scheduler) scheduling tool provided by IBM can be used to integrate multiple JCL jobs into a JCL job stream. In this way, by using the scheduling tool, the JCL job stream can be automatically generated without the need for manual generation through input instructions.

[0111] 2) Receive the JCL job stream returned by the scheduling tool; the JCL job stream includes the JCL job.

[0112] Correspondingly, submitting the JCL job to the host operating system for processing may include: submitting the JCL job flow to the host operating system for processing.

[0113] In some embodiments, when the host operating system adopts the Z / OS operating system, submitting the JCL job to the host operating system for processing may refer to: submitting the JCL job to the JES2 (Job Entry Subsystem 2) subsystem and the SDSF (System Display and Search Facility) subsystem of the Z / OS operating system for processing. Among them, the JES2 subsystem is a bottom-level and most basic subsystem of the Z / OS operating system. It is mainly responsible for receiving jobs, parsing job content, controlling job execution, controlling job output, etc. The SDSF subsystem is also a relatively basic subsystem of the Z / OS operating system, which is mainly used to provide users with system information to help users monitor, manage and control the Z / OS operating system.

[0114] Combination Figure 5 As shown, in some embodiments, taking the case where the call instruction is initiated by the user end as an example, after the JCL job is submitted to the host operating system for processing, it can be processed by the JES2 / SDSF subsystem of the Z / OS operating system. It should be pointed out that since the SDSF subsystem can monitor, manage and control the JES2 subsystem, the two can be regarded as one subsystem for the operation and maintenance device; for the sake of ease of description, in the embodiments of this specification, the two are collectively referred to as the JES2 / SDSF subsystem. The JES2 / SDSF subsystem can parse the received JCL job into a JCL job command, and then send the JCL job command to the address space (such as the ADVISOR address space, etc.) for execution. After the JCL job command is processed in the address space, the return value will be automatically returned to the JES2 / SDSF subsystem. Among them, the return value can be used to describe the execution result of the JCL job.

[0115] Please continue to combine Figure 5 As shown, in some embodiments, obtaining the processing result of the JCL job from the host operating system may include: grabbing the return value of the JCL job from the SDSF subsystem of the JES2 / SDSF subsystem, and comparing the return value with the expected return value; and determining whether the return value meets the preset conditions based on the comparison result, so as to identify whether the execution is successful.

[0116] For example, in one embodiment, meeting the preset conditions may mean that: the return value is lower than the expected return value, that is, when the return value is lower than the expected return value, the JCL job can be considered to have been successfully executed. Correspondingly, when the return value does not meet the preset conditions, the JCL job can be considered to have failed to execute. Based on the identification of whether the return value meets the preset conditions, the processing result of the JCL job can be generated and returned to the corresponding user end for the output display of the user end. When the JCL job fails to execute, the JCL job automatically stops, waiting for confirmation by the operation and maintenance personnel. When the JCL job fails to execute, the returned processing result may also include failure cause information (such as xxx component abnormality and other information) to prompt the operation and maintenance personnel to deal with it.

[0117] Those skilled in the art can understand that for a JCL job flow, when each job in the JCL job flow is successfully executed, the entire JCL job flow is considered to be successfully executed. For example, in an exemplary embodiment, a JCL job flow includes JCL job 1, JCL job 2 and JCL job 3, a total of three JCL jobs, and the execution order is JCL job 1 → JCL job 2 → JCL job 3. If JCL job 1 is successfully executed, JCL job 2 is executed; if JCL job 2 is successfully executed, JCL job 3 is executed. When JCL job 3 is also successfully executed, it indicates that the JCL job flow is successfully executed.

[0118] Combination Figure 6 As shown, in other embodiments, in the scenario where the calling command is initiated by the job calling program, the processing logic of the JES2 / SDSF subsystem and the operation and maintenance device are basically the same. One of the main differences is that the operation and maintenance device main program returns the processing result of the JCL job to the job calling program so that the job calling program adds the processing result of the JCL job to the job processing result queue.

[0119] In some other embodiments, in the scenario where the call command is initiated by the job call program, the execution judgment of "comparing the return value with the expected return value and determining whether the return value meets the preset condition according to the comparison result" can also be implemented by the job call program. For example, in some embodiments, the job call program can call the scheduling tool to implement it. Therefore, this manual does not limit this, and the specific selection can be made according to needs.

[0120] Although the process flows described above include multiple operations that occur in a particular order, it should be clearly understood that the processes may include more or fewer operations, which may be performed sequentially or in parallel (eg, using parallel processors or a multi-threaded environment).

[0121] Corresponding to the above-mentioned host active-active system operation and maintenance method, this specification also provides a host active-active system operation and maintenance device, which can be configured on any suitable computer device. Figure 7 As shown, in some embodiments, the operation and maintenance device may include:

[0122] The receiving module 71 may be used to receive a call instruction for a target operation and maintenance operation interface;

[0123] A generating module 72, which can be used to call a JCL job generating script according to the calling instruction to generate a JCL job;

[0124] A submission module 73 may be used to submit the JCL job to a host operating system for processing;

[0125] The acquisition module 74 may be used to acquire the processing result of the JCL job from the host operating system.

[0126] In some device embodiments, the receiving module 71 receives a call instruction for a target operation and maintenance interface, which may include:

[0127] After providing a user interface including an operation and maintenance operation interface option to a user terminal, a selection operation of the user terminal for the operation and maintenance operation interface option is received.

[0128] In some other device embodiments, the receiving module 71 receives a call instruction for a target operation and maintenance interface, which may include:

[0129] Receive the call instruction for the target operation and maintenance operation interface sent by the job caller.

[0130] In some device embodiments, the JCL job generation script generates a JCL job in the following manner:

[0131] Querying a JCL job template matching the calling instruction from a preset JCL job template set;

[0132] The JCL job template is modified according to the specified parameters in the calling instruction to obtain a corresponding JCL job.

[0133] In some device embodiments, the operation and maintenance device may further include a job stream receiving module, which may be used to: provide the JCL job generated by the generation module to the scheduling tool for processing before the submission module submits the JCL job to the host operating system for processing; receive the JCL job stream returned by the scheduling tool; the JCL job stream includes the JCL job. Correspondingly, the submission module submitting the JCL job to the host operating system for processing may include: submitting the JCL job stream to the host operating system for processing.

[0134] In some device embodiments, the operation and maintenance interface options may include:
