Description

情報処理装置、リクエスト処理方法及びコンピュータ読み取り可能な記録媒体Information processing apparatus, request processing method, and computer-readable recording medium
　本発明は、たとえば、リクエストを処理する情報処理装置等に関する。 The present invention relates to an information processing apparatus that processes a request, for example.
　サーバ・クライアントシステムは、業務処理等を実行するアプリケーションを用いてサービスを提供する少数のサーバと、サーバが該サービスを受ける要求（以降、「リクエスト」とも表す）に応じて提供するサービスを受け取る多数のクライアントとを有する。サーバ・クライアントシステムにおいては、サーバは、多数のクライアントが送信するリクエストを、許容時間内に処理し、処理した結果（以降、「レスポンス」とも表す。）をクライアントに返答する。このため、サーバは、高性能な処理能力を有する。 The server / client system receives a small number of servers that provide services using applications that execute business processing and the like, and a large number of services that are provided according to requests that the servers receive the services (hereinafter also referred to as “requests”). With clients. In the server / client system, the server processes requests transmitted by a large number of clients within an allowable time, and returns the processed result (hereinafter also referred to as “response”) to the client. For this reason, the server has a high-performance processing capability.
　サーバ・クライアントシステムを運用する場合において、クライアント数は、該サーバ・クライアントシステムを設計する時点において想定していたクライアント数よりも多くなる傾向がある。また、サーバ・クライアントシステムにおいて、サーバが、新たに追加されるサービスや、設計する時点において想定していた処理量以上のデータを処理することになる傾向がある。このため、サーバは、高性能な処理能力を有していたとしても、クライアントから受け取るリクエストを、許容時間内に処理できないこともある。この場合、サーバが提供するサービスは遅延する。 When a server / client system is operated, the number of clients tends to be larger than the number of clients assumed at the time of designing the server / client system. Further, in the server / client system, the server tends to process a service to be newly added or data exceeding the processing amount assumed at the time of designing. For this reason, even if the server has a high-performance processing capability, it may not be able to process the request received from the client within the allowable time. In this case, the service provided by the server is delayed.
　サーバ・クライアントシステムにおいてサービスが遅延する一因は、上記のように、クライアントが、設計する時点において想定していた処理量よりも多くの処理量を一度に要求することである。あるいは、サービスが遅延する一因は、多くのクライアントが同時期にサービスを要求することである。 One reason for the delay in service in the server / client system is that, as described above, the client requests a larger amount of processing at a time than the amount of processing assumed at the time of designing. Alternatively, one reason for service delays is that many clients request services at the same time.
　処理量が増えることに起因する遅延を軽減する方法としては、特許文献１が開示するサーバコンピュータシステムのように、サーバがクライアントから実際にリクエストを受け取る前に、あらかじめ該リクエストに応じた処理を行う方法がある。 As a method of reducing the delay caused by the increase in the processing amount, as in the server computer system disclosed in Patent Document 1, before the server actually receives the request from the client, the processing corresponding to the request is performed in advance. There is a way.
　該サーバコンピュータシステムは、まず、リクエストに関する規則性を統計的な手法を用いて解析し、得られた規則性を統計データとして記憶装置に保存する。次に、該サーバコンピュータシステムは、記憶装置に保存する規則性に基づき、次に送受信するリクエストを予測する。次に、該サーバコンピュータシステムは、予測したリクエストに基づき、該リクエストに関する処理を実行し、実際にクライアントからリクエストを受けるのに応じて、実行した結果を出力する。 The server computer system first analyzes the regularity of the request using a statistical technique, and stores the obtained regularity as statistical data in a storage device. Next, the server computer system predicts the next request to be transmitted / received based on the regularity stored in the storage device. Next, the server computer system executes processing related to the request based on the predicted request, and outputs the execution result in response to the request actually received from the client.
特許第３４８０７９４号公報Japanese Patent No. 3480794
　しかし、統計的な手法は、必ずしも正しい予測を行うとは限らない。統計データがノイズを含む場合等に、特許文献１が開示するサーバコンピュータシステムは、ノイズを含む統計データに基づき、リクエストを予測する。したがって、該サーバコンピュータシステムにおける予測精度は、必ずしも高くはない。この場合、該サーバコンピュータシステムは、誤って予測したリクエストに関する処理を実行する。 However, statistical methods do not always make correct predictions. When the statistical data includes noise, the server computer system disclosed in Patent Document 1 predicts a request based on the statistical data including noise. Therefore, the prediction accuracy in the server computer system is not necessarily high. In this case, the server computer system executes a process related to an erroneously predicted request.
　この結果、該サーバコンピュータシステムは、実際にクライアントからリクエストを受け取る場合に、受け取ったリクエストを実行する。したがって、リクエストを処理する時間は遅延する。 As a result, when the server computer system actually receives a request from a client, the server computer system executes the received request. Therefore, the time for processing the request is delayed.
　そこで、本発明の主たる目的は、リクエストを高速に処理する情報処理装置等を提供することである。 Therefore, a main object of the present invention is to provide an information processing apparatus that processes requests at high speed.
　前述の目的を達成するために、本発明に係る情報処理装置は、以下の構成を備えることを特徴とする。 In order to achieve the above object, an information processing apparatus according to the present invention is characterized by having the following configuration.
　すなわち、本発明の一態様に係る情報処理装置は、
　第１情報処理装置がオブジェクトプログラムを実行する状況に応じて、前記オブジェクトプログラムの基であるソースプログラムからリクエストを抽出するリクエスト抽出手段と、
　前記リクエストに応じた処理を実行し、実行した結果をレスポンスとするリクエスト実行手段と、
　前記第１情報処理装置が前記リクエストを要求するのに応じて、前記レスポンスを前記第１情報処理装置に送信する送信手段と
　を備える。 That is, an information processing device according to one embodiment of the present invention is provided.
Request extraction means for extracting a request from a source program that is a basis of the object program according to a situation in which the first information processing apparatus executes the object program;
Request execution means for executing processing according to the request and using the execution result as a response;

　また、本発明の他の見地として、本発明の一態様に係るリクエスト処理方法は、
　　第１情報処理装置がオブジェクトプログラムを実行する状況に応じて、前記オブジェクトプログラムの基であるソースプログラムからリクエストを抽出し、
　　前記リクエストに応じた処理を実行し、実行した結果をレスポンスとし、

Execute the process according to the request, the execution result as a response,
The response is transmitted to the first information processing device in response to the first information processing device requesting the request.
　さらに、同目的は、係るプログラム、および、そのプログラムを記録するコンピュータ読み取り可能な記録媒体によっても実現される。 Furthermore, this object is also realized by such a program and a computer-readable recording medium for recording the program.
　本発明に係る情報処理装置等によれば、リクエストを高速に処理することができる。 The information processing apparatus according to the present invention can process a request at high speed.

　本実施形態に係る情報処理装置（「サーバ」とも表す。）１０１は、リクエスト抽出部１０２と、リクエスト実行部１０３と、送信部１０４とを有する。 The information processing apparatus (also referred to as “server”) 101 according to the present embodiment includes a request extraction unit 102, a request execution unit 103, and a transmission unit 104.
　情報処理装置１０１は、通信ネットワーク３００１を介して、第１情報処理装置（「クライアント」とも表す。）３００２との間において、リクエスト等を含む情報を送受信する。 The information processing apparatus 101 transmits and receives information including requests and the like to and from the first information processing apparatus (also referred to as “client”) 3002 via the communication network 3001.
　説明の便宜上、第１情報処理装置３００２は、オブジェクトプログラムを実行するとする。また、オブジェクトプログラムは、ソースプログラムを変換することにより得られるとする。 For convenience of explanation, it is assumed that the first information processing apparatus 3002 executes an object program. The object program is obtained by converting the source program.
　まず、リクエスト抽出部１０２は、たとえば、図３に示すソースプログラムを、図４に示すような解析手法を用いて解析する。リクエスト抽出部１０２は、第１情報処理装置３００２において実行されるオブジェクトプログラムに変換される基となるソースプログラムを静的に解析する。これにより、リクエスト抽出部１０２は、第１情報処理装置３００２が情報処理装置１０１に対し要求するリクエストを予測する。 First, for example, the request extraction unit 102 analyzes the source program shown in FIG. 3 by using an analysis method as shown in FIG. The request extraction unit 102 statically analyzes a source program that is a basis to be converted into an object program executed in the first information processing apparatus 3002. Accordingly, the request extraction unit 102 predicts a request that the first information processing apparatus 3002 requests the information processing apparatus 101.
　図３は、リクエスト抽出部１０２が解析するソースプログラムの一例を表す図である。図４は、解析手法の一例を表す図である。図３に示すソースプログラムは、第１情報処理装置３００２において実行されるオブジェクトプログラムに変換される基となるものである。 FIG. 3 is a diagram illustrating an example of a source program analyzed by the request extraction unit 102. FIG. 4 is a diagram illustrating an example of an analysis method. The source program shown in FIG. 3 is a basis for conversion into an object program executed in the first information processing apparatus 3002.
　図３に示すソースプログラムは、Ｃ言語を用いて記述されたプログラムである。該ソースプログラムにおいて、「Ｏｐｅｒａｔｉｏｎ１」乃至「Ｏｐｅｒａｔｉｏｎ５」は、第１情報処理装置３００２が情報処理装置１０１に対し要求するリクエストである。 The source program shown in FIG. 3 is a program written using C language. In the source program, “Operation 1” to “Operation 5” are requests that the first information processing apparatus 3002 requests the information processing apparatus 101.
　第１情報処理装置３００２は、該ソースプログラムに従い、リクエスト「Ｏｐｅｒａｔｉｏｎ１」を要求し、その後、リクエスト「Ｏｐｅｒａｔｉｏｎ１」に対する結果をパラメタ（「変数」とも表す）ａに保存する。次に、第１情報処理装置３００２は、パラメタａが正であると判定する場合に、リクエスト「Ｏｐｅｒａｔｉｏｎ２」を要求する。逆に、第１情報処理装置３００２は、パラメタａが正でないと判定する場合に、リクエスト「Ｏｐｅｒａｔｉｏｎ３」を要求する。 The first information processing apparatus 3002 requests the request “Operation1” according to the source program, and then stores the result for the request “Operation1” in the parameter (also referred to as “variable”) a. Next, when determining that the parameter a is positive, the first information processing apparatus 3002 requests the request “Operation2”. Conversely, the first information processing apparatus 3002 requests the request “Operation3” when determining that the parameter a is not positive.
　また、図４が示すグラフ構造における各節点（ノード）は、命令を表す。また、各枝（エッジ）は、条件分岐（たとえば、ｉｆ命令等）における条件を表す。 Each node in the graph structure shown in FIG. 4 represents an instruction. Each branch (edge) represents a condition in a conditional branch (for example, an if instruction).
　たとえば、図４の１列目におけるノードは、ｍａｉｎ関数（図３における「ｍａｉｎ（）」）を表す。また、図４の２列目におけるノードは、「第１情報処理装置がリクエスト「Ｏｐｅｒａｔｉｏｎ１」を要求し、次に、リクエスト「Ｏｐｅｒａｔｉｏｎ１」に対する結果をパラメタａに保存し、さらに、パラメタｂを読み取る」処理を表す。さらに、図４の２列目におけるノードと、図４の３列目の左側のノードを結ぶエッジは、図３における５列目の条件分岐における条件が成り立つ場合を表す。 For example, the node in the first column in FIG. 4 represents a main function (“main ()” in FIG. 3). Further, the node in the second column in FIG. 4 indicates that “the first information processing apparatus requests the request“ Operation1 ”, then stores the result for the request“ Operation1 ”in the parameter“ a ”, and further reads the parameter“ b ”. Represents a process. Further, the edge connecting the node in the second column in FIG. 4 and the left node in the third column in FIG. 4 represents a case where the condition in the conditional branch in the fifth column in FIG. 3 is satisfied.
　次に、リクエスト抽出部１０２は、第１情報処理装置３００２がオブジェクトプログラムを実行する状況に応じて、ソースプログラムからリクエストを抽出する（ステップＳ２０１）。 Next, the request extraction unit 102 extracts a request from the source program according to the situation in which the first information processing apparatus 3002 executes the object program (step S201).
　たとえば、第１情報処理装置３００２が、図３における１行目（ｍａｉｎ（））を実行する場合に、リクエスト抽出部１０２は、第１情報処理装置３００２が次に要求するリクエスト「Ｏｐｅｒａｔｉｏｎ１」を抽出する。また、第１情報処理装置３００２が、図３における４行目（ｓｃａｎｆ命令）を実行する場合に、リクエスト抽出部１０２は、第１情報処理装置３００２が次に要求するリクエスト「Ｏｐｅｒａｔｉｏｎ２」及びリクエスト「Ｏｐｅｒａｔｉｏｎ３」を抽出する。 For example, when the first information processing apparatus 3002 executes the first line (main ()) in FIG. 3, the request extraction unit 102 extracts the request “Operation1” that the first information processing apparatus 3002 next requests. To do. When the first information processing apparatus 3002 executes the fourth line (scan instruction) in FIG. 3, the request extraction unit 102 requests the request “Operation2” and the request “ “Operation3” is extracted.
　リクエスト抽出部１０２は、抽出したリクエストを、図５に示すような情報としてまとめてもよい。図５は、リクエスト抽出部１０２が抽出するリクエストの一例を概念的に表す図である。たとえば、図５に示す例において、リクエスト「Ｏｐｅｒａｔｉｏｎ１」は、クライアント２００（第１情報処理装置３００２の１つ）に関連付けされている。これは、クライアント２００は、オブジェクトプログラムにおいて、リクエスト「Ｏｐｅｒａｔｉｏｎ１」を要求することを表す。 The request extraction unit 102 may collect the extracted requests as information as shown in FIG. FIG. 5 is a diagram conceptually illustrating an example of a request extracted by the request extraction unit 102. For example, in the example illustrated in FIG. 5, the request “Operation1” is associated with the client 200 (one of the first information processing devices 3002). This represents that the client 200 requests the request “Operation1” in the object program.
　リクエストは、上述した項目以外の項目を含んでいてもよく、上述した例に限定されない。 The request may include items other than the items described above, and is not limited to the example described above.
　次に、リクエスト実行部１０３は、リクエスト抽出部１０２が抽出したリクエストに応じた処理を実行し、実行した結果をレスポンスとする（ステップＳ２０２）。リクエスト抽出部１０２が複数のリクエストを抽出した場合、本実施形態におけるリクエスト実行部１０３は、各リクエストに応じた処理を実行する。しかし、後述の実施形態に示すように、リクエストをさらに絞り込むことにより実行してもよい。 Next, the request execution unit 103 executes processing according to the request extracted by the request extraction unit 102, and sets the execution result as a response (step S202). When the request extraction unit 102 extracts a plurality of requests, the request execution unit 103 in the present embodiment executes processing according to each request. However, as shown in an embodiment described later, the request may be executed by further narrowing down the requests.
　上述した例において、リクエスト実行部１０３は、リクエスト「Ｏｐｅｒａｔｉｏｎ１」に応じた処理を実行し、値１０を第１情報処理装置３００２に送信するとする。この場合に、第１情報処理装置３００２は、図６に示すようなレスポンスを作成する。図６は、リクエスト実行部１０３が作成するレスポンスの一例を概念的に表す図である。 In the example described above, the request execution unit 103 executes processing according to the request “Operation1” and transmits the value 10 to the first information processing apparatus 3002. In this case, the first information processing apparatus 3002 creates a response as shown in FIG. FIG. 6 is a diagram conceptually illustrating an example of a response created by the request execution unit 103.
　レスポンスは、上述した項目以外の項目を含んでいてもよく、上述した例に限定されない。 The response may include items other than the items described above, and is not limited to the example described above.
　図６に示すレスポンスは、クライアント２００と、リクエスト「Ｏｐｅｒａｔｉｏｎ１」と、値１０とを関連付けする。すなわち、これは、クライアント２００が要求したリクエスト「Ｏｐｅｒａｔｉｏｎ１」に対する実行結果が１０であることを表す。 The response shown in FIG. 6 associates the client 200 with the request “Operation1” and the value 10. That is, this indicates that the execution result for the request “Operation 1” requested by the client 200 is 10.
　また、リクエスト実行部１０３は、リクエストに応じた処理を実行する際にエラーが生じる場合には、該エラーを表すエラーメッセージをレスポンスとしてもよい。 Further, when an error occurs when executing the process according to the request, the request execution unit 103 may use an error message indicating the error as a response.
　次に、送信部１０４は、第１情報処理装置３００２が実際にリクエスト要求するのに応じて、リクエスト実行部１０３が算出したレスポンスを第１情報処理装置３００２に送信する（ステップＳ２０３）。 Next, the transmission unit 104 transmits the response calculated by the request execution unit 103 to the first information processing device 3002 in response to the first information processing device 3002 actually requesting the request (step S203).
　本実施形態に係る情報処理装置１０１は、第１情報処理装置３００２にて実行されるオブジェクトプログラムの基となるソースプログラムに基づき、第１情報処理装置が要求するリクエストを予測する。そして、情報処理装置１０１は、第１情報処理装置３００２が実際に要求する前に、予測したリクエストに応じた処理を実行する。このため、情報処理装置１０１は、第１情報処理装置３００２がリクエストするのに応じて、すぐにレスポンスを送ることができる。 The information processing apparatus 101 according to the present embodiment predicts a request requested by the first information processing apparatus based on a source program that is a basis of an object program executed by the first information processing apparatus 3002. Then, the information processing apparatus 101 executes processing according to the predicted request before the first information processing apparatus 3002 actually requests it. Therefore, the information processing apparatus 101 can immediately send a response in response to the request from the first information processing apparatus 3002.
　一方、特許文献１が開示するサーバコンピュータシステムは、リクエストに関する統計データに基づき、リクエストを予測する。統計データが誤差を含む場合に、該統計データに基づいた予測が正確でなくなるので、該サーバコンピュータシステムは、誤ったリクエストを処理する。この結果、サーバコンピュータシステムにおいては、処理効率は低下する。 On the other hand, the server computer system disclosed in Patent Document 1 predicts a request based on statistical data regarding the request. If the statistical data contains an error, the server computer system processes an incorrect request because the prediction based on the statistical data becomes inaccurate. As a result, processing efficiency decreases in the server computer system.
　すなわち、第１の実施形態に係る情報処理装置によれば、リクエストを高速に処理することができる。 That is, according to the information processing apparatus according to the first embodiment, requests can be processed at high speed.
　尚、上述した例において、第１情報処理装置３００２は、オブジェクトプログラムを実行するとした。しかし、本実施形態は、Ｗｅｂにおけるアプリケーションにも適用可能である。たとえば、情報処理装置１０１は、サーバ（情報処理装置１０１）からクライアント（第１情報処理装置３００２の１つ）に送信するＷｅｂデータ（レスポンス）を上述したソースプログラムとして解析してもよい。この場合における情報処理装置１０１の一例として、送信部１０４は、第１の情報処理装置３００２にWebデータを送信する。また、リクエスト抽出部１０２は、上述したWebデータをソースプログラムとして解析する。すなわち、本実施形態は、上述した例に限定されない。 In the above example, the first information processing apparatus 3002 executes the object program. However, this embodiment can also be applied to Web applications. For example, the information processing apparatus 101 may analyze Web data (response) transmitted from a server (information processing apparatus 101) to a client (one of the first information processing apparatuses 3002) as the above-described source program. As an example of the information processing apparatus 101 in this case, the transmission unit 104 transmits Web data to the first information processing apparatus 3002. Further, the request extraction unit 102 analyzes the Web data described above as a source program. That is, this embodiment is not limited to the above-described example.
　＜第２の実施形態＞
　次に、上述した第１の実施形態を基本とする本発明の第２の実施形態について説明する。 <Second Embodiment>
Next, a second embodiment of the present invention based on the first embodiment described above will be described.
　以下の説明においては、本実施形態に係る特徴的な部分を中心に説明すると共に、上述した第１の実施形態と同様な構成については、同一の参照番号を付すことにより、重複する説明を省略する。 In the following description, the characteristic part according to the present embodiment will be mainly described, and the same components as those in the first embodiment described above will be denoted by the same reference numerals, and redundant description will be omitted. To do.
　図７と図８とを参照しながら、第２の実施形態に係る情報処理装置７０１が有する構成と、情報処理装置７０１が行う処理とについて説明する。図７は、本発明の第２の実施形態に係る情報処理装置７０１が有する構成を示すブロック図である。図８は、第２の実施形態に係る情報処理装置７０１における処理の流れを示すフローチャートである。 The configuration of the information processing apparatus 701 according to the second embodiment and the processing performed by the information processing apparatus 701 will be described with reference to FIGS. FIG. 7 is a block diagram showing the configuration of the information processing apparatus 701 according to the second embodiment of the present invention. FIG. 8 is a flowchart showing the flow of processing in the information processing apparatus 701 according to the second embodiment.
　本実施形態に係る情報処理装置７０１は、リクエスト抽出部１０２と、リクエスト実行部１０３と、送信部７０２と、パラメタ抽出部７０３とを有する。 The information processing apparatus 701 according to the present embodiment includes a request extraction unit 102, a request execution unit 103, a transmission unit 702, and a parameter extraction unit 703.
　情報処理装置７０１は、通信ネットワーク３００１を介して、第１情報処理装置３００２との間において、リクエスト等を含む情報を送受信する。 The information processing apparatus 701 transmits / receives information including a request to / from the first information processing apparatus 3002 via the communication network 3001.
　パラメタ抽出部７０３は、ソースプログラムからパラメタを抽出する（ステップＳ８０１）。パラメタ抽出部７０３により抽出されるパラメタは、第１情報処理装置３００２がリクエスト実行部１０３にて生成されたレスポンスを受け取り、該レスポンスに基づいてオブジェクトプログラムを継続して実行する場合に必要である。パラメタ抽出部７０３は、例えばソースプログラムを解析することにより、パラメタを抽出する。パラメタ抽出部７０３は、さらに、該パラメタに関する型を抽出してもよい。 The parameter extraction unit 703 extracts parameters from the source program (step S801). The parameters extracted by the parameter extraction unit 703 are necessary when the first information processing apparatus 3002 receives the response generated by the request execution unit 103 and continuously executes the object program based on the response. The parameter extraction unit 703 extracts parameters by, for example, analyzing a source program. The parameter extraction unit 703 may further extract a type related to the parameter.
　たとえば、ソースプログラムが図３に示すプログラムである場合、リクエスト抽出部１０２は、リクエスト「Ｏｐｅｒａｔｉｏｎ１」をソースプログラムから抽出したとする。
リクエスト実行部１０３は、リクエスト「Ｏｐｅｒａｔｉｏｎ１」を実行し、実行した結果をレスポンスとする。 For example, when the source program is the program shown in FIG. 3, it is assumed that the request extraction unit 102 extracts the request “Operation1” from the source program.
The request execution unit 103 executes the request “Operation1” and uses the execution result as a response.
　次に、パラメタ抽出部７０３は、ソースプログラムにおいてリクエスト「Ｏｐｅｒａｔｉｏｎ１」以降に実行する命令のうち、利用者がパラメタを入力する必要がある命令及び該パラメタを抽出する。この例の場合、ｓｃａｎｆ命令は、利用者がパラメタを入力する必要がある命令である。このため、パラメタ抽出部７０３は、ｓｃａｎｆ命令、及び、パラメタｂを抽出する。 Next, the parameter extraction unit 703 extracts an instruction that requires a user to input a parameter from instructions executed after the request “Operation 1” in the source program and the parameter. In this example, the scan instruction is an instruction that requires the user to input parameters. For this reason, the parameter extraction unit 703 extracts a scan instruction and a parameter b.
　たとえば、パラメタ抽出部７０３は、抽出したパラメタを図９に示すような情報として算出してもよい。図９は、パラメタ抽出部７０３が抽出するパラメタに関する情報の一例を概念的に表す図である。図９において、クライアント２００（第１情報処理装置３００２の一つ）は、パラメタｂに関連付けされている。これは、クライアント２００において、利用者がパラメタｂを入力する必要があることを表す。 For example, the parameter extraction unit 703 may calculate the extracted parameters as information as shown in FIG. FIG. 9 is a diagram conceptually illustrating an example of information regarding parameters extracted by the parameter extraction unit 703. In FIG. 9, the client 200 (one of the first information processing devices 3002) is associated with the parameter b. This indicates that the user needs to input the parameter b in the client 200.
　次に、送信部７０２は、第１情報処理装置３００２が実際にリクエストを要求するのに応じて、リクエスト実行部１０３が作成したレスポンスと、パラメタ抽出部７０３が抽出したパラメタとを第１情報処理装置３００２に送信する（ステップＳ８０２）。 Next, in response to the first information processing apparatus 3002 actually requesting the request, the transmission unit 702 displays the response created by the request execution unit 103 and the parameters extracted by the parameter extraction unit 703 as the first information processing. The data is transmitted to the device 3002 (step S802).
　尚、送信部７０２は、第１情報処理装置３００２に、レスポンスとパラメタとを逐次的に送信してもよいし、同時に送信してもよい。すなわち、送信部７０２がレスポンスとパラメタと送信する順序は、上述した例に限定されない。 Note that the transmission unit 702 may sequentially transmit responses and parameters to the first information processing apparatus 3002, or may transmit them simultaneously. That is, the order in which the transmission unit 702 transmits the response, the parameter, and the parameter is not limited to the above-described example.
　第２の実施形態は、上記説明した構成以外の構成は、第１の実施形態と同様の構成を有するため、第２の実施形態は、第１の実施形態と同様の効果を奏する。すなわち、第２の実施形態に係る情報処理装置によれば、リクエストを高速に処理することができる。 Since the second embodiment has the same configuration as the first embodiment except for the configuration described above, the second embodiment has the same effects as the first embodiment. That is, according to the information processing apparatus according to the second embodiment, a request can be processed at high speed.
　さらに、第２の実施形態に係る情報処理装置７０１は、オブジェクトプログラムを継続して実行する状況において、利用者が入力するパラメタを抽出し、抽出したパラメタを第１情報処理装置３００２に送信する。この場合、利用者は、第１情報処理装置３００２においてレスポンスを受け取るまでに、パラメタ抽出部７０３が抽出したパラメタを入力することもできる。したがって、本実施形態によれば、リクエストを送信してからレスポンスを受信するまでの待ち時間を利用者に意識させない効果も有する。 Furthermore, the information processing apparatus 701 according to the second embodiment extracts parameters input by the user in a situation where the object program is continuously executed, and transmits the extracted parameters to the first information processing apparatus 3002. In this case, the user can input the parameter extracted by the parameter extraction unit 703 until the first information processing apparatus 3002 receives the response. Therefore, according to this embodiment, there is also an effect that does not make the user aware of the waiting time from when a request is transmitted until when a response is received.
　＜第３の実施形態＞
　次に、上述した第１の実施形態を基本とする本発明の第３の実施形態について説明する。 <Third Embodiment>
Next, a third embodiment of the present invention based on the first embodiment described above will be described.
　以下の説明においては、本実施形態に係る特徴的な部分を中心に説明すると共に、上述した第１の実施形態と同様な構成については、同一の参照番号を付すことにより、重複する説明を省略する。 In the following description, the characteristic part according to the present embodiment will be mainly described, and the same components as those in the first embodiment described above will be denoted by the same reference numerals, and redundant description will be omitted. To do.
　図１０と図１１とを参照しながら、第３の実施形態に係る情報処理装置１００１が有する構成と、情報処理装置１００１が行う処理とについて説明する。図１０は、本発明の第３の実施形態に係る情報処理装置１００１が有する構成を示すブロック図である。図１１は、第３の実施形態に係る情報処理装置１００１における処理の流れを示すフローチャートである。 The configuration of the information processing apparatus 1001 according to the third embodiment and the processing performed by the information processing apparatus 1001 will be described with reference to FIGS. 10 and 11. FIG. 10 is a block diagram showing a configuration of the information processing apparatus 1001 according to the third embodiment of the present invention. FIG. 11 is a flowchart showing the flow of processing in the information processing apparatus 1001 according to the third embodiment.
　本実施形態に係る情報処理装置１００１は、リクエスト抽出部１００３と、リクエスト実行部１０３と、送信部１０４と、実行部１００２とを有する。 The information processing apparatus 1001 according to the present embodiment includes a request extraction unit 1003, a request execution unit 103, a transmission unit 104, and an execution unit 1002.
　情報処理装置１００１は、通信ネットワーク３００１を介して、第１情報処理装置３００２との間において、リクエスト等を含む情報を送受信する。 The information processing apparatus 1001 transmits and receives information including requests and the like to and from the first information processing apparatus 3002 via the communication network 3001.
　まず、実行部１００２は、第１情報処理装置３００２がオブジェクトプログラムを実行する状況に応じて、該オブジェクトプログラムを実行する。このようにすることで、実行部１００２は、情報処理装置１００１において、第１情報処理装置３００２における状態を算出する（ステップＳ１１０１）。すなわち、実行部１００２は、第１情報処理装置３００２における状態を再現する。なお、この場合において、状態は、ソースプログラムにおけるパラメタの値を含む。また、状態は、ソースプログラムにおいて、パラメタの値に応じて処理が分岐する場合における条件分岐等を含んでいてもよい。状態は、上述した例に限定されない。 First, the execution unit 1002 executes the object program according to the situation in which the first information processing apparatus 3002 executes the object program. By doing in this way, the execution part 1002 calculates the state in the 1st information processing apparatus 3002 in the information processing apparatus 1001 (step S1101). That is, the execution unit 1002 reproduces the state in the first information processing device 3002. In this case, the state includes a parameter value in the source program. In addition, the state may include a conditional branch in the case where the process branches according to the parameter value in the source program. The state is not limited to the example described above.
　図３に示す例を参照しながら、情報処理装置１００１における処理について説明する。 Processing in the information processing apparatus 1001 will be described with reference to the example illustrated in FIG.
　たとえば、第１情報処理装置３００２は、ソースプログラムの先頭から順次処理し、その後、リクエスト「Ｏｐｅｒａｔｉｏｎ１」を処理した結果を情報処理装置１００１から受け取った状態であるとする。 For example, it is assumed that the first information processing apparatus 3002 receives the result of processing the request “Operation1” from the information processing apparatus 1001 after sequentially processing from the top of the source program.
　この場合、実行部１００２は、第１情報処理装置３００２と同様に、ソースプログラムにおける先頭から順次処理し、その後、リクエスト「Ｏｐｅｒａｔｉｏｎ１」を処理した結果を、情報処理装置１００１から受け取った状態を算出する。 In this case, as in the first information processing apparatus 3002, the execution unit 1002 sequentially processes from the top in the source program, and then calculates the state of receiving the result of processing the request “Operation1” from the information processing apparatus 1001. .
　次に、リクエスト抽出部１００３は、実行部１００２が算出する状態とソースプログラムとに基づきリクエストを抽出する（ステップＳ１１０２）。 Next, the request extraction unit 1003 extracts a request based on the state calculated by the execution unit 1002 and the source program (step S1102).
　図３に示すソースプログラム例の場合、たとえば、パラメタａの値が０であったとする。 In the example of the source program shown in FIG. 3, for example, assume that the value of parameter a is 0.
　この場合、パラメタａの値に応じて、処理は、図３における５行目に示す分岐命令（すなわち、ｉｆ命令文）において分岐する。パラメタａは０であるため、分岐命令における条件判定は成立しない。このため、リクエスト抽出部１００３は、ソースプログラムに基づき、処理が図３における１２行目に示す処理に推移すると判定することにより、リクエスト「Ｏｐｅｒａｔｉｏｎ３」を抽出する。 In this case, according to the value of the parameter a, the process branches at a branch instruction (that is, an if statement) shown on the fifth line in FIG. Since parameter a is 0, the condition determination in the branch instruction is not satisfied. Therefore, the request extraction unit 1003 extracts the request “Operation3” by determining that the process shifts to the process indicated by the 12th line in FIG. 3 based on the source program.
　第３の実施形態は、上記説明した構成以外の構成は、第１の実施形態と同様の構成を有するため、第３の実施形態は、第１の実施形態と同様の効果を奏する。すなわち、第３の実施形態に係る情報処理装置によれば、リクエストを高速に処理することができる。 Since the third embodiment has the same configuration as the first embodiment except for the configuration described above, the third embodiment has the same effect as the first embodiment. That is, according to the information processing apparatus according to the third embodiment, requests can be processed at high speed.
　さらに、リクエスト抽出部１００３は、ソースプログラムと、実行部１００２が算出する状態とに基づき、リクエストを抽出する。すなわち、実行部１００２がオブジェクトプログラムを実行することで、リクエスト抽出部１００３は、第１情報処理装置３００２における状態を反映した上でリクエストを抽出することができる。このため、リクエスト抽出部１００３は、第１の実施形態に比べ、さらに、リクエストを絞り込む機能を有する。この場合、リクエスト実行部１０３における処理量は、リクエスト抽出部１００３が抽出するリクエストに応じて決まるため、第１の実施形態に比べ減少する。 Further, the request extraction unit 1003 extracts a request based on the source program and the state calculated by the execution unit 1002. That is, when the execution unit 1002 executes the object program, the request extraction unit 1003 can extract a request while reflecting the state in the first information processing apparatus 3002. For this reason, the request extraction unit 1003 further has a function of narrowing down the requests as compared with the first embodiment. In this case, since the processing amount in the request execution unit 103 is determined according to the request extracted by the request extraction unit 1003, it is reduced compared to the first embodiment.
　すなわち、本実施形態は、上述した効果に加え、さらに、処理時間が減少する効果を有する。 That is, this embodiment has an effect of further reducing the processing time in addition to the above-described effect.
　（ハードウェア構成例）
　上述した本発明の各実施形態における情報処理装置を、１つの計算処理装置（情報処理装置、コンピュータ）を用いて実現するハードウェア資源の構成例について説明する。但し、係る情報処理装置は、物理的または機能的に少なくとも２つの計算処理装置を用いて実現してもよい。また、係る情報処理装置は、専用の装置として実現してもよい。 (Hardware configuration example)
A configuration example of hardware resources for realizing the information processing apparatus according to each embodiment of the present invention described above using one calculation processing apparatus (information processing apparatus, computer) will be described. However, the information processing apparatus may be realized using at least two calculation processing apparatuses physically or functionally. The information processing apparatus may be realized as a dedicated apparatus.
　図１２は、第１の実施形態乃至第３の実施形態に係る情報処理装置を実現可能な計算処理装置のハードウェア構成を概略的に示す図である。計算処理装置２０は、中央処理演算装置（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ、以降「ＣＰＵ」と表す）２１、メモリ２２、ディスク２３、不揮発性記録媒体２４、入力装置２５、および、出力装置２６を有する。 FIG. 12 is a diagram schematically illustrating a hardware configuration of a calculation processing apparatus that can realize the information processing apparatus according to the first to third embodiments.
