Description

  The present invention relates to a technique for testing data update processing in a database system or the like.

  2. Description of the Related Art In a modern society in which computerization is rapidly progressing, large-scale database systems that provide various services in various fields are being constructed. In order to improve the availability of such a database system, various techniques have been developed for efficiently testing data update processing in the database system.

  For example, in an online database system or the like, when simulating an operation using data of a master database, there is a method of creating a replica (replica) of the master database and performing an update process on the replica. However, this method has a problem that when a large number of records are stored in the master database, a large-capacity storage area is required to create the replica.

  Further, there is a method of directly updating a master database when performing a simulation and applying a journal after the simulation is completed, thereby returning the updated data to the original value. However, in these methods described above, it is necessary to temporarily stop the business using the master database. Therefore, there is an increasing expectation for a technique for testing the operation of the database system at a low cost without stopping the operation of the database system.

  As an example of such a technique, Patent Literature 1 discloses a database update control method that simulates an operation without affecting a master database. In this method, it is determined whether the latest image of the data requested to be searched is present in the database or the updated image file. According to this method, data requested to be retrieved is retrieved from a database or an updated image file in accordance with the determination result. This method updates the extracted data and registers the updated data in an updated image file. In this method, the latest image of the updated data is managed in the updated image file.

  Further, Patent Document 2 discloses an apparatus in which when testing a database processing program, the influence of the test is separated from the production data by dividing the data into production data and test data. This apparatus stores execution mode information that defines a production mode and a test mode. This device associates an application execution unit (AP execution unit) with an execution mode using the execution mode information. This device transmits execution mode information when the AP execution unit requests connection to the database. This apparatus establishes a connection by generating a production or test connection based on the execution mode information. This apparatus stores data processed by the AP execution unit as production data or test data. When the data is updated, the device specifies the version of the updated production data or test data.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First embodiment>
FIG. 1 is a block diagram conceptually showing a configuration of a data update control device 10 according to the first embodiment of the present invention. The data update control device 10 is a device that can test an update process on the database in parallel while operating a service using the database. The data update control device 10 performs an update process on a database used by a user according to an instruction from the operation application (business application) 20. A plurality of operation applications 20 may exist. The data update control device 10 performs a test, such as a simulation, on an update process for the database in accordance with an instruction from the test application 30. The operation application 20 and the test application 30 are communicatively connected to the data update control device 10, or are executed in an information processing device such as a server device including the data update control device 10.

  The data update control device 10 according to the present embodiment includes an operation AP (application) update unit (first update unit) 11, a storage unit 12, an operation AP storage unit (first storage unit) 13, and a save record storage. A second storage unit 14, a test AP update unit (second update unit) 15, and a test AP storage unit (third storage unit) 16. The operating AP update unit 11, the storage unit 12, and the test AP update unit 15 may be electronic circuits, or may be realized by a computer program and a processor that operates according to the computer program. The working AP storage unit 13, the save record storage unit 14, and the test AP storage unit 16 are storage devices such as a memory or a magnetic disk. Each of these storage units has an electronic circuit or a storage control function realized by a computer program and a processor operating according to the computer program. Note that these storage units may not be provided in the data update control device 10. For example, these storage units may be provided in an external storage device or the like that is communicably connected to the data update control device 10.

  The save record storage unit 14, the test AP update unit 15, and the test AP storage unit 16 are configured to operate as the test control function 100. The test control function 100 starts operating when the test application 30 starts operating. For example, when the test control function 100 is realized by a computer program, the data update control device 10 realizes the test AP update unit 15 and the storage control functions of the save record storage unit 14 and the test AP storage unit 16. Is started (activated) when the operation of the test application 30 starts.

  The operation AP update unit 11 performs an update process on the operation AP database 130 stored in the operation AP storage unit 13 according to an instruction from the operation application 20. FIG. 2 is a diagram illustrating a configuration of the operational AP database 130 according to the present embodiment. As illustrated in FIG. 2, the operational AP database 130 is data including one or more records in which items of “record generation”, “primary key”, and “user data” are associated.

  In FIG. 2, "primary key" is key information for specifying "user data" in the database. The “record generation” is given to the specific record by the operation AP update unit 11 when the update (including addition of a new record) to the specific record is performed by the operation AP update unit 11. Information.

  As shown in FIG. 1, the operation AP update unit 11 stores the generation information 110 in, for example, a built-in memory or the like. The operating AP update unit 11 adds “1” to the value indicated by the generation information 110 each time an update process is performed on any record in the operating AP database 130, and the generation information 110 indicates the record. Assign a value. That is, the generation information 110 is a value indicating the number of times that the update process for the active AP database 130 has been performed by the active AP update unit 11. Therefore, the “record generation” in the operation AP database 130 is a value indicated by the generation information 110 when the record is updated, that is, information indicating the update generation.

  The storage unit 12 refers to the evacuation record information 140 stored in the evacuation record storage unit 14 when any record in the operation AP database 130 is updated by the operation AP updating unit 11. FIG. 3 is a diagram illustrating a configuration of the save record information 140 according to the present embodiment. As illustrated in FIG. 3, the save record information 140 is data including one or more records in which items “primary key” and “user data” are associated with each other.

  The record included in the evacuation record information 140 indicates a state before the update of the record in the operation AP database 130, which is updated by the operation AP update unit 11 after the test application 30 starts operating. The storage unit 12 confirms whether or not a record having the same “primary key” as the record in the working AP database 130 updated by the working AP updating unit 11 exists in the save record information 140.

  If the record does not exist in the save record information 140, the storage unit 12 adds the record in a state before being updated by the active AP update unit 11 to the save record information 140. When the record exists in the save record information 140, the storage unit 12 does not perform the operation of adding the record in the operation AP database 130 to the save record information 140.

  The save record storage unit 14 starts operation after the test application 30 starts operation, as described above. Therefore, when the operation AP update unit 11 first updates a specific record in the operation AP database 130 after the test application 30 starts operating, the storage unit 12 stores the specific record before the update. Is added to the save record information 140. In the examples shown in FIGS. 2 and 3, the records in which the “primary key” is “Key2”, “Key3”, and “Key5” are updated by the operation AP updating unit 11 after the test application 30 starts operating. Have been. In the save record information 140, “Data2a”, “Data3a”, and “Data5a” are “Key2” and “Key3” as the values of the “user data” before the update for the updated records, respectively. , “Key5” and stored. It should be noted that “Data2b”, “Data3b”, and “Data5b” shown in FIG. 2 correspond to a record whose “primary key” is “Key2”, “Key3”, and “Key5” in the updated “user data”. Indicates a value.

  The test AP update unit 15 performs a test by simulating an update process for the operation AP database 130 according to an instruction from the test application 30. The test AP update unit 15 reads the value indicated by the generation information 110 stored in the operation AP update unit 11 when the test application 30 starts operating, and uses the read value as the start generation information 150. , For example, in a built-in memory. That is, the start generation information 150 indicates the value of the generation information 110 when the test application 30 starts operating.

  When updating any record in the operational AP database 130 to be tested according to an instruction from the test application 30, the test AP updating unit 15 determines that the record having the same “primary key” as the record is stored in the test AP storage. It is confirmed whether or not it exists in the test AP database 160 stored in the unit 16.

  After the test application 30 starts operating, the test AP database 160 stores the result of the test AP update unit 15 updating any record in the operational AP database 130 in accordance with an instruction from the test application 30. I have. The configuration of the test AP database 160 is the same as the configuration of the save record information 140 shown in FIG.

  When a record having the same “primary key” as the record in the operational AP database 130 to be tested exists in the test AP database 160, the test AP updating unit 15 updates the record. If the record having the same “primary key” as the record to be tested does not exist in the test AP database 160, the test AP updating unit 15 determines that the record having the same “primary key” as the record is the operating AP Check whether it exists in the database 130. In this case, the record to be tested is a record that has not yet been updated by the test application 30 after the test application 30 started operating.

  Here, the absence of the record in the active AP database 130 means that the record has been deleted from the active AP database 130 by the active AP update unit 11. In this case, the test AP updating unit 15 checks whether a record having the same “primary key” as the record exists in the save record information 140. When the record exists, the test AP update unit 15 reads the record from the save record information 140, updates the read record, and adds the update result to the test AP database 160.

  When a record having the same “primary key” as the record to be tested does not exist in the test AP database 160 but exists in the operational AP database 130, the test AP updating unit 15 The value of “generation” is compared with the value indicated by the start generation information 150. Here, the fact that the value indicated by the start generation information 150 is larger than the value of the “record generation” of the record means that the test application 30 starts the operation when the operation AP update unit 11 updates the record. It means that it precedes the timing that was done.

  When the value indicated by the start generation information 150 is equal to or greater than the “record generation” value of the record, the test AP update unit 15 reads the record from the operation AP database 130. When the value indicated by the start generation information 150 is less than the value of the “record generation” of the record, the test AP updating unit 15 confirms that the record exists in the save record information 140, and then saves the record. Read from the record information 140. The test AP updating unit 15 updates the record read from the operational AP database 130 or the save record information 140, and adds the update result to the test AP database 160.

  Next, the operation (process) of the data update control device 10 according to the present embodiment will be described in detail with reference to the flowcharts of FIGS.

  FIG. 4 is a flowchart illustrating an operation in which the data update control device 10 according to the present embodiment updates the operation AP database 130 according to an instruction from the operation application 20.

  The operation AP update unit 11 receives an instruction to update the operation AP database 130 from the operation application 20 (step S101). The operation AP update unit 11 confirms whether the content of the instruction is update or deletion of a record or addition of a record (step S102).

  If the content of the instruction is not update or deletion of a record (that is, addition of a record) (No in step S103), the operation AP updating unit 11 sets a value obtained by adding 1 to the generation information 110 as a “record generation”. The set addition target record is added to the operational AP database 130 (step S104). The operation AP updating unit 11 adds “1” to the generation information 110 (step S111), and the entire process ends.

  If the content of the instruction is to update or delete the record (Yes in step S103), the storage unit 12 checks whether a record having the same “primary key” as the target record exists in the save record information 140 (step S105). ). If the record does not exist in the save record information 140 (No in step S106), the storage unit 12 replaces the record in the active AP database 130 with the same “primary key” as the record to be updated or deleted with the save record It is added to the information 140 (step S107).

  If the content of the instruction is to update a record (Yes in step S108), the operating AP update unit 11 updates the update target record in the operating AP database 130, and sets the value of the “record generation” to the generation information. The value is set to a value obtained by adding 1 to 110 (step S109), and the process proceeds to step S111. When the content of the instruction is not the update of the record (that is, the deletion of the record) (No in step S108), the operation AP update unit 11 deletes the record to be deleted from the operation AP database 130 (step S111). ), The process proceeds to step S111.

  FIG. 5 is a flowchart illustrating an operation in which the data update control device 10 according to the present embodiment adds a record to the test AP database 160 according to an instruction of the test application 30.

  The test AP update unit 15 receives an instruction to add a record to the operational AP database 130 from the test application 30 (Step S201). The test AP updating unit 15 checks whether a record having the same “primary key” as the record to be added exists in the test AP database 160 (step S202).

  If the record exists in the test AP database 160 (Yes in step S203), the test AP update unit 15 reports to the test application 30 that the addition of the record has failed (step S204), and performs the entire process. Ends.

  If the record does not exist in the test AP database 160 (No in step S203), the test AP update unit 15 checks whether a record having the same “primary key” as the record to be added exists in the operation AP database 130. (Step S205). If the record exists in the operation AP database 130 (Yes in step S206), the value of the “record generation” of the searched record is compared with the value of the start generation information 150 (step S207).

  When the value of the start generation information 150 is equal to or larger than the value of the “record generation” (Yes in step S208), the process proceeds to step S204. When the value of the start generation information 150 is less than the value of the “record generation” (No in step S208), the test AP updating unit 15 determines that the record having the same “primary key” as the record to be added is included in the save record information 140. It is checked whether it exists (step S209).

  If the record exists in the save record information 140 (Yes in step S210), the process proceeds to step S204. If the record does not exist in the save record information 140 (No in step S210), the test AP updating unit 15 adds the addition target record to the test AP database 160 (step S211), and the entire process ends. I do.

  FIG. 6 is a flowchart showing an operation in which the data update control device 10 according to the present embodiment updates or deletes a record in the test AP database 160 according to an instruction from the test application 30.

  The test AP update unit 15 receives an instruction to update or delete a record in the operational AP database 130 from the test application 30 (step S301). The test AP updating unit 15 checks whether a record having the same “primary key” as the target record exists in the test AP database 160 (step S302).

  If the record exists in the test AP database 160 (Yes in step S303), the test AP update unit 15 updates the target record in the test AP database 160 or deletes the target record (step S304). , The entire process ends.

  If the record does not exist in the test AP database 160 (No in step S303), the test AP update unit 15 checks whether a record having the same “primary key” as the target record exists in the operation AP database 130. (Step S305). When the record exists in the operation AP database 130 (Yes in step S306), the test AP update unit 15 compares the value of the “record generation” of the retrieved record with the value of the start generation information 150. (Step S307).

  When the value of the start generation information 150 is equal to or larger than the value of the “record generation” (Yes in step S308), the test AP updating unit 15 reads the record from the operation AP database 130 (step S309). The test AP update unit 15 updates the read record, adds the update result to the test AP database 160 (step S313), and ends the entire process.

  When the value of the start generation information 150 is less than the value of the “record generation” (No in step S308), the test AP updating unit 15 includes a record having the same “primary key” as the target record in the save record information 140. Confirmation is made (step S310). If the record exists in the save record information 140 (Yes in step S311), the test AP updating unit 15 reads the record from the save record information 140 (step S312), and the process proceeds to step S313. If the record does not exist in the save record information 140 (No in step S311), the test AP update unit 15 reports to the test application 30 that the target record does not exist (step S314), and the entire process ends. I do.

  When the record having the same “primary key” as the target record does not exist in the operation AP database 130 (No in step S306), the test AP updating unit 15 proceeds to step S310.

The data update control device 10 according to the present embodiment can use the data used by the operating database system or the like to test the update processing of the data without affecting the operation. Can be performed efficiently in a state close to The reason is that the data update control device 10 operates as follows. That is,
The operation AP update unit 11 updates the record of the operation AP database 130 in association with the generation information 110 at the time of update.
When the record of the operation AP database 130 is updated for the first time after the operation of the test application 30 is started, the storage unit 12 stores the value before the update of the record as the save record information 140.
The test AP update unit 15 converts the record to be updated based on the result of comparison between the value of the generation information regarding the record to be updated in the operation AP database 130 and the value of the start generation information 150 into the database for the operation AP. The update is performed by reading from the save record information 140 or the save record information 140, and the update result is stored as the test AP database 160.

  Hereinafter, effects achieved by the data update control device 10 according to the present embodiment will be described in detail.

  Expectation for technology that efficiently tests data update processing using data used by operating database systems, etc., in a state close to the actual operation situation without affecting operation Is growing. In such a technique, a problem is to be able to read a record so that a test can be performed on a database at an arbitrary time.

  In order to deal with such a problem, in the data update control device 10 according to the present embodiment, the operation AP update unit 11 operates the operation AP database 130 stored in the operation AP storage unit 13 in accordance with an instruction from the operation application 20. To update. At this time, the operating AP update unit 11 updates the target record included in the operating AP database 130 by associating the target record with the generation information 110. The generation information 110 is information indicating the order relationship between the update timing and the timing at which the test application 30 that performs a test using the operational AP database 130 starts operating. The storage unit 12 stores the target record before update in the save record storage unit 14 when the operation AP update unit 11 first updates the target record after the test application 30 starts operating. The test AP update unit 15 updates the target record included in the operation AP database 130 according to an instruction from the test application 30. At this time, in the first case, the generation information associated with the target record indicates that the update timing is earlier than the update information for the target AP. read out. If the generation information associated with the target record indicates that the update timing is later, the test AP updating unit 15 stores the target record before update stored in the save record storage unit 14 in the second case. Is read. The test AP update unit 15 updates the read target record in the first and second cases, and stores the update result in the test AP storage unit 16.

  That is, the data update control device 10 according to the present embodiment saves the pre-update value of the record updated by the operation application 20 to the save record storage unit 14 after the test application 30 starts operating. The data update control device 10 manages, for each record, the order relationship between the timing updated by the operation application 20 and the timing at which the test application 30 starts operating. Then, the data update control device 10 reads and updates the target record from the working AP storage unit 13 or the evacuation record storage unit 14 based on the order relationship, and stores the update result in the test AP storage unit 16. . Accordingly, the data update control device 10 according to the present embodiment can use the data used by the operating database system or the like to test the updating process of the data without affecting the operation. It can be performed efficiently in a state close to the operation status of.

  Further, the data update control device 10 according to the present embodiment includes the generation information 110 that adds a value when updating a record, and the start generation information 150 that indicates the value of the generation information 110 when the test application 30 starts operating. Manages the above-described order relationship, but the order relationship may be managed by another method. The data update control device 10 may manage the order relationship based on, for example, the time when the record is updated and the time when the test application 30 starts operating.

  Further, the data update control device 10 according to the present embodiment has a test control function so that, for example, a plurality of test applications 30 having different start times can test an update process on the operation AP database 130 without affecting each other. 100 may be provided. In this case, the individual test control functions 100 operate independently without affecting each other. For example, when the test control function 100 is realized by a computer program, the data update control device 10 starts up a process for realizing the test control function 100 every time the test application 30 starts operating. That is, the data update control device 10 according to the present embodiment can more efficiently perform a test of an update process on an operating database system or the like by performing a plurality of tests (simulations) in parallel.

  When updating the record 430 stored in the first storage unit 43 in accordance with an instruction from the operation application 50, the first update unit 41 performs a test using the update timing and a test using the record 430. 60 is updated in association with order information 410 indicating the order relationship with the timing at which the operation starts.

  The storage unit 42 stores the record 440 before the update in the second storage unit 44 when the first update unit 41 first updates the record 430 after the test application 60 starts operating.

  The second updating unit 45 updates the record 430 stored in the first storage unit 43 according to an instruction from the test application 60 as described below. That is, in the first case where the order information 410 associated with the record 430 indicates that the update timing is earlier, the second update unit 45 stores the record 430 stored in the first storage unit 43. Is read. If the order information 410 associated with the record 430 indicates that the update timing is later, the second update unit 45 stores the record before the update stored in the second storage unit 44.
