Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method, an apparatus, and a program for executing a batch application at high speed.
[0002]
A batch application is a software program that collectively processes data to be processed. Normally, there are two forms of business application execution: an online application and a batch application. In an online application, processing such as a slip is performed in real time. And collectively process the stored data.
[0003]
[Prior art]
Conventionally, for example, when performing batch application processing using a DB in a client / server system that accesses a database (hereinafter, referred to as “DB”), connect / disconnect to / from a DB (eg, “ORACLE” (registered trademark)) is performed for each batch application. Connect processing was being performed. Here, the connect process is a process for connecting to the DB management system in order to access the DB, and the disconnect process is a process for ending the access to the DB and disconnecting the connection with the DB management system.
[0004]
FIG. 14 is a diagram illustrating the operation of a conventional batch application. In the figure, reference numeral 10 denotes a batch application information file, and reference numeral 11 denotes a batch application. The batch application information file 10 is a file in which information necessary for executing the batch application 11 is stored. As shown in FIG. 14, conventionally, the batch application information file 10 was read and the batch application 11 was activated. Each batch application 11 executes a connect process to the DB at the time of startup, and executes a disconnect process to the DB at the time of termination.
[0005]
Regarding the operation processing of the batch application, no prior art document describing a technique for shortening the execution time and speeding up the processing has been found.
[0006]
[Problems to be solved by the invention]
In the above-mentioned prior art, since the connect / disconnect processing for the DB is performed for each batch application, there is a problem that the processing time becomes longer in proportion to the number of batch applications.
[0007]
That is, in the case of operating a batch application of a business application composed of a plurality of job steps, in the related art, a process of each batch application is started for each job step, and a DB connect / disconnect process is performed for each process of each job step. Therefore, there is a problem in that the DB connect / disconnect process takes a long time, and the batch application process becomes slow. Note that the DB connect / disconnect processing may require a processing time of 2 to 3 seconds depending on the system load.
[0008]
Not only the problem of the time required for the DB connect / disconnect processing as described above, but also the problem of the execution of a large number of batch applications in the following cases, the processing takes a long time and the processing load increases. there were.
(1) It takes time (start time of about 1 second) for the start processing of the job execution control.
(2) When common development with EJB (Enterprise-Java Beans) is attempted, a batch application is developed with Java (registered trademark). Conventionally, a Java virtual machine (Java VM) is used for each job step of the batch application. , And it takes time (1-2 seconds) for the Java VM to start.
[0009]
Since online applications are required to respond in real time, various measures have been taken to increase the speed. However, batch applications for offline processing, such as batch input of jobs and batch output of processing results, require immediate response. Since no performance was required, little consideration was given to speeding up the processing.
[0010]
Comparing the batch application and the online application, the processing speed of the batch application is much slower than the processing speed of the online application. In the online application, processing of 100 transactions / second (TPS) can be aimed at. Per minute (TPM).
[0011]
In recent business applications, the number of batch applications tends to increase. However, when the number of batch applications increases, it is not desirable that processing time be longer as in the past, even in batch processing.
[0012]
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to enable high-speed processing of a large number of batch applications.
[0013]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
FIG. 1 is a diagram showing a configuration example of an apparatus for implementing the present invention. In the figure, 100 is a data processing device including a CPU and a memory, 1 is a batch application, 2 is a batch execution for generating a program execution control unit (thread), issuing an execution instruction to the program execution control unit and executing the batch application. Processes 4, 4 'are program execution controllers (threads) for executing batch applications.
[0020]
In the batch execution process 2, the program execution control unit generation unit 20 generates a predetermined number of threads of the program execution control units 4, 4 '. The execution request receiving unit 21 receives an execution request of each batch application 1. The execution waiting management unit 22 queues the execution request of the batch application 1 in the execution waiting queue 23. If there is a free space in the program execution control units 4, 4 ', the batch application execution command unit 24 issues an execution command to the program execution control units 4, 4'.
[0021]
The program execution control unit 4 (similarly for 4 ′) includes batch application common processing units 40 and 41 and a batch application calling unit 42. The batch application common processing unit 40 is an execution part of essential processing that must be executed first in common by all the batch applications 1. For example, when the batch application 1 is a program for accessing a database, the DB connect processing Is the part that executes Further, when the batch application 1 is a Java program, this is a part for executing a JavaVM activation process and the like.
[0022]
The batch application common processing unit 41 is an execution part of essential processing that must be executed last by all the batch applications 1. For example, when the batch application 1 is a program that accesses a database, the DB disconnection is performed. This is the part that executes processing. Further, when the batch application 1 is a Java program, this section executes processing for terminating the Java VM.
[0023]
The batch application calling unit 42 is a processing unit that calls and executes the designated batch application 1 according to an execution command from the batch application execution command unit 24 of the batch execution process 2. The batch application 1 operates in a form such as a function call or a subroutine call on a thread of the program execution control unit 4. In the case of an object-oriented system, the batch application 1 may be realized as one or a plurality of objects.
[0024]
When the program execution control unit 4 is generated from the batch execution process 2 and started, the program execution control unit 4 first executes the processing by the batch application common processing unit 40 only once, and thereafter executes the processing by the execution instruction from the batch application execution instruction unit 24. Call one batch application 1 at a time. When the processing of the batch application 1 is completed, the execution instruction of the next batch application 1 can be accepted, and the batch application calling unit 42 repeatedly calls the batch application 1 for each execution instruction until the end instruction is given. . When there is an execution end instruction from the batch execution process 2, the process by the batch application common processing unit 41 is executed only once at the end, and the process ends.
[0025]
In the example shown in FIG. 1, the program execution control unit 4 first executes the processing by the batch application common processing unit 40 in response to the execution request of the batch applications A, B, C,. The batch application A is called by the batch application calling unit 42 and processed by the batch application calling unit 42 for the execution instruction (A) from On the other hand, the batch application calling unit 42 'calls and processes the batch application B. The other execution requests C, D, E,... Are connected to the execution waiting queue 23.
[0026]
When the execution of the batch application A ends, the batch application calling unit 42 of the program execution control unit 4 calls and processes the batch application C according to the next execution instruction (C) from the batch application execution instruction unit 24.
[0027]
In the prior art, it is necessary to execute the processing by the batch application common processing unit 40 such as the DB connect processing for each batch application, whereas in the present invention, the program execution control unit 4 executes the processing. The processing of the batch application common processing unit 40 in the batch application 1 becomes unnecessary.
[0028]
FIG. 2 is a diagram illustrating an example of execution control of a batch application according to the embodiment of the present invention. In the present embodiment, it is assumed that the processing of the batch application common processing unit 40 in FIG. 1 is a DB connect, and the processing of the batch application common processing unit 41 is a DB disconnect.
[0029]
In the figure, reference numeral 3 denotes a start process for requesting the batch execution process 2 to execute a batch application, reference numeral 5 denotes a parameter file in which parameters necessary for starting the start process 3 are written, and reference numeral 6 denotes a batch application such as an execution program name. A batch application information file in which information is written, 7 is an initialization file in which information necessary for initializing the batch execution process 2 is written, 8 is information such as a batch execution process name, an execution multiplicity, and the number of log files. Is a parameter file written.
[0030]
The parameter file 5 is read to activate the activation process 3. Further, the initialization file 7 and the parameter file 8 are read in order to start the batch execution process 2.
[0031]
Hereinafter, an operation example of the present embodiment will be described with reference to (a) to (f) shown in FIG.
(A) First, the contents of the initialization file 7 and the contents of the parameter file 8 are read, and the batch execution process 2 is started.
(B) The batch execution process 2 generates a program execution control unit (thread) 4 based on the contents of the parameter file 8. Then, the batch execution process 2 issues an instruction to the program execution control unit (thread) 4 based on the contents of the initialization file 7 and causes each program execution control unit (thread) 4 to connect to the DB.
(C) Thereafter, in order to request the execution of the batch application 1, the parameter file 5 and the batch application information file 6 are read, and the activation process 3 is started.
(D) The start process requests the batch execution process 2 to execute the batch application 1 based on the contents of the parameter file 5 and the batch application information file 6 passed by the command argument. Note that the execution request from the start-up process 3 to the batch execution process 2 uses a TCP / IP communication protocol.
(E) When the batch execution process 2 receives the execution request from the start process 3, the batch execution process 2 fetches the parameters of the received execution request, determines the condition of the execution possibility, and executes the currently available program execution control unit (thread) 4 Issue a command. If there is no currently free program execution control unit (thread) 4, the received execution request is queued in the execution queue 23 and put into an execution waiting state.
(F) Upon receiving the execution instruction of the batch application 1, the program execution control unit (thread) 4 starts the batch application 1 having the specified execution program name. When the execution of the batch application 1 is completed, the completion of the execution is reported to the batch execution process 2 and the next execution instruction of the batch application 1 is waited.
[0032]
After all the batch applications 1 have been executed, the program execution control unit (thread) 4 disconnects the DB according to an instruction from the batch execution process 2 and closes the thread.
[0033]
As described above, in the embodiment of the present invention, the connection process (connect) to the DB is performed only once for each of the plurality of program execution control units (threads) 4 generated at the time of starting the system, and once when the system is terminated. Only the disconnection processing (disconnect) to the DB is performed. When the batch application 1 is executed, the batch application 1 is always called from the program execution control unit (thread) 4. In the program execution control unit (thread) 4, the connection processing to the DB has already been completed and the connection state is maintained, so that it is not necessary to perform the connection / disconnection processing to the DB for each batch application 1.
[0034]
FIG. 3 is a diagram showing a flow of the initial processing according to the embodiment of the present invention. When starting the system, first, the initialization file 7 is read in order to start the batch execution process 2 (step S1). FIG. 4 shows an example (SUSVINIT) of the initialization file 7. As shown in FIG. 4, for example, the initialization file 7 includes a user name for accessing the DB, a password of the user accessing the DB, an instance name, a maximum size of a log file, a level for outputting a log, a maximum number of log files, and an instance. (In the case of Java), a JDBC (Java Database Connectivity) driver name (in the case of Java), and information on whether to execute the COBOL business application. JDBC is a standard application program interface (API) for accessing a DB from a Java program.
[0035]
Next, the parameter file 8 is read (step S2). FIG. 5 shows an example of the parameter file 8 (fbdef.txt). In the parameter file 8, for example, as shown in FIG. 5, an execution indicating the name of the batch execution process, the language type such as C / COBOL / Java, the port number (No), and the number of program execution control units (threads) 4 to be generated Information such as the multiplicity, the maximum number of queues that are the maximum number of execution requests that can be connected waiting for execution (MAX queue), the working folder for copying parameter files, the folder for writing log files, and the number of log file files are written. .
[0036]
The batch execution process 2 is started by reading the initialization file 7 and the parameter file 8 (steps S1 and S2) (step S3). After that, the batch execution process 2 generates the program execution control units (threads) 4 for the number of execution multiplicity specified in the parameter file 8 (step S4).
[0037]
FIG. 6 is a diagram illustrating a flow of a program execution control unit (thread) generation process according to the embodiment of the present invention. First, the batch execution process 2 generates the program execution control units (threads) 4 for the parameter file execution multiplicity (step S11). The program execution control unit (thread) 4 is started (step S12). The program execution control unit (thread) 4 first connects to the DB (step S13) and waits for an execution instruction. After generating all the program execution control units (threads) 4, the batch execution process 2 waits for an execution request.
[0038]
FIG. 7 is a diagram showing a batch application execution processing flow in the embodiment of the present invention. When the batch application 1 is executed, the parameter file 5 is first read in order to start the start-up process 3 according to an instruction of an operator or by an automatic start-up process of the system (step S21). FIG. 8 shows an example of the parameter file 5 (fbdef.txt). In the parameter file 5, for example, as shown in FIG. 8, a batch execution process name, a language type such as C / COBOL / Java, a port number (No), an execution multiplicity, and a maximum number of queues are written.
[0039]
Next, the batch application information file 6 is read (step S22). FIG. 9 shows an example of the batch application information file 6 (inp1.txt). In the batch application information file 6, information necessary for the execution of the batch application 1, such as an execution program name, discontinuation elapsed time, data 1, data 2, company code, and base code, as shown in FIG. 9, is written. Have been.
[0040]
Specifically, in the information written in the batch application information file 6 shown in FIG. 9, "pgm = pgm1" is a key for searching for a batch application name ("pgm1") to be executed on the batch execution process 2. “Time = 20” indicates that when waiting on the batch execution process 2, the timeout to wait is 20 seconds.
[0041]
Also, “data1 = 11111111” and “data2 = 22222222” are arguments specific to the batch application 1 to be executed, and “cdcompany = 000” is a company used for searching the DB area on the batch application 1 to be executed. “Cdstore = 000” is a key of a base code used for searching the DB area on the batch application 1 to be executed.
[0042]
Next, activation of the activation process 3 is performed (step S23). Thereafter, the batch execution process shown in FIG. 10 is performed (step S24). In response to an execution instruction from the batch execution process 2, the program execution control unit (thread) 4 performs a calling process of the batch application 1 (step S25), and executes the batch application 1 (step S26).
[0043]
FIG. 10 is a diagram showing a flow of the batch execution process in step S24 of FIG. First, the batch execution process 2 receives an execution request from the activation process 3 (step S31). Next, it is determined whether or not the number of execution requests in the current execution queue 23 has reached the value of the MAX queue (the maximum number of execution requests) (step S32), and the current number of execution requests is set to the value of the MAX queue. If not, error information is set, and the start process 3 is notified that the execution request cannot be accepted (step S35).
[0044]
If the current number of waiting execution requests is smaller than the value of the MAX queue, it is determined whether the execution multiplicity and the number of active threads are different (step S33). That is, it is determined whether there is a free thread in which the batch application 1 is not currently executed. If there is a free thread, an execution instruction is sent to the program execution control unit (thread) 4 to execute the batch application 1 (step S34). If the execution multiplicity and the number of active threads are the same and there is no free thread, the received execution request is queued in the execution waiting queue 23 and waits until a free thread is created (step S36).
[0045]
FIG. 11 is a diagram showing a flow of the end processing according to the embodiment of the present invention. When the end of the batch execution process 2 is instructed by terminating all the batch applications 1 or by an instruction from the operator or the like (step S41), the batch execution process 2 firstly starts the program execution control units (threads) 4 (Step S42). The program execution control unit (thread) 4 performs DB disconnection (step S43), and ends (step S44). The batch execution process 2 ends after confirming the end of the program execution control unit (thread) 4 (step S45).
[0046]
FIG. 12 is a diagram showing a data flow up to the start of the batch application.
(1) The startup process 3 reads the batch application information file 6 shown in FIG.
(2) The data read in the start process 3 is transmitted to the batch execution process 2 by TCP / IP communication in a message format shown in FIG.
(3) A hash map as shown in FIG. 12C is created on the batch execution process 2 based on the message transmitted from the activation process 3. The hash map is data in which parameters and keys necessary for executing the batch application 1 are collected.
(4) The hash map shown in FIG. 12C is sent to the vacant program execution control unit (thread) 4. If there are no free threads, wait for a free thread until the timeout value. If the timeout value is exceeded, do nothing and terminate with an error.
(5) The batch application “pgm1” is executed using the hash map data shown in FIG. 12D as an argument. In the process in pgm1, data is input based on each key of the argument.
[0047]
FIG. 13 is a sequence diagram of the batch application execution process according to the embodiment of the present invention. In FIG. 13, an example will be described in which the batch application A and the batch application B, which are business applications that perform data processing by connecting to the DB and performing disconnection from the DB after the operation is completed, are described as an example. Further, it is assumed that the business applications (batch application A and batch application B) have been developed in Java, for example.
[0048]
In FIG. 13, first, when the batch execution process 2 is started (a), the batch execution process 2 generates a program execution control unit (thread) 4, issues an instruction to the program execution control unit (thread) 4, and connects to the DB connection. (B).
[0049]
Next, when the start process 3 starts (c), the start process 3 requests the batch execution process 2 to execute (d). The batch execution process 2 issues an execution instruction to the currently free program execution controller (thread) 4 (e). Upon receiving the execution instruction, the program execution control unit (thread) 4 generates a business application class, calls and executes the batch application A (f). When the execution processing is completed, the batch execution process 2 receives an execution completion notification from the program execution control unit (thread) 4 (g).
[0050]
When the activation process 3 is activated again (h), the activation process 3 requests the batch execution process 2 to execute (i). The batch execution process 2 issues an execution instruction to the currently free program execution controller (thread) 4 (j). Upon receiving the execution instruction, the program execution control unit (thread) 4 generates a business application class, calls and executes the batch application B (k).
[0051]
The batch execution process 2 receives the execution completion notification from the program execution control unit (thread) 4 (l), and then, after confirming that there is no batch application to be executed, issues an instruction to the program execution control unit (thread) 4. To disconnect the DB, and perform termination processing (m).
