JP 2004-157794 A Japanese Patent Laid-Open No. 11-134228

  The following analysis was made by the present inventors.

  The function of referring to the test result in the hospital information system is intended to support medical diagnosis. However, when a sudden failure occurs or maintenance is performed as necessary, it is necessary to stop the system. Assuming that the system is stopped, it is possible to create a backup database using the database replication function so that at least past data can be referred to. However, in the medical field where it is required to always provide a service, it is a problem to refer only to past data, not in real time, even for a short period of time.

  With respect to referring to an electronic medical record at the time of a failure in a hospital information system, a system that can refer to past data by a method of installing a backup server is known. However, in actual clinical practice, not only referencing past data but also real-time test results are required, so switching to paper-based operation or using results from the test system as a recovery means is used. It is done.

  According to the electronic medical record system described in Patent Document 1, since electronic medical record data is stored in both the first server (order server) and the second server (medical record server), even if one server stops. Data can be read from the other server.

  According to the backup system described in Patent Document 2, the data of the first server (electronic medical record server) is converted into HTML data in real time and stored in the second server (backup server). Even when the server becomes inaccessible, the HTML data of the second server can be accessed.

  However, according to the systems described in Patent Document 1 and Patent Document 2, when the first server is stopped, the data that can be read from the second server is limited to data before the first server is stopped. It is done. Therefore, there is a problem that medical information collected after the first server is stopped cannot be read.

  Therefore, in a redundant system in which collected information is provided by a plurality of servers, even if some servers are stopped, it is possible to continue providing information collected after the servers are stopped. It becomes a problem to do. An object of the present invention is to provide a redundancy system, a redundancy method, and a program that solve such problems.

  A redundant system according to a first aspect of the present invention includes an information collection device, a first server, and a second server connected via a network. The information collection device collects and collects information. Information transmitted to the first server and the second server, and the first server and the second server receive and accumulate the information collected by the information collection device, and accumulate in response to a request from the client Provide information.

  In the redundancy method according to the second aspect of the present invention, the information collection device collects information and sends the collected information to the first server and the second server connected to the information collection device via the network. A transmitting step, a step in which the first server and the second server receive and store the information collected by the information collecting device, and the first server or the second server responds to a request from the client. And providing information accumulated in this manner.

  The program according to the third aspect of the present invention collects information and collects information by collecting the collected information to a first server and a second server connected to the information collecting apparatus via a network. A process for receiving and storing information collected by the information collecting apparatus, a process for providing information accumulated in response to a request from the client, and a first server and a second server CPU is executed.

  According to the redundant system, the redundancy method, and the program according to the present invention, in a redundant system that provides collected information by a plurality of servers, even if some servers are stopped, information collected after that Can continue to provide.
