Recording medium, distribution controlling method, and information processing device

摘要

A computer acquires a particular entry(ies) from a database that includes plural entries for each of which a key is determined; stores the particular entry(ies) into a memory provided in the computer and used as one of memories that store the database in a distributed manner; and associates a particular piece of communication endpoint information with a network interface of the computer. Each key for each particular entry belongs to a particular subset among mutually disjoint subsets of a domain of keys. The particular piece of the communication endpoint information is one of a predetermined number of pieces of the communication endpoint information and is associated with the particular subset. Each piece of the communication endpoint information logically identifies one communication endpoint, is dynamically associated with one network interface which provides access to one of the memories, and is statically associated with one of the subsets.

1. A computer-readable recording medium having stored therein a distribution controlling program for causing a computer to execute a process comprising:
receiving an assignment instruction for assigning data which corresponds to a first key region and is part of a database, the first key region being defined by one or a plurality of keys and being one of a plurality of key regions of the database, the database being partitioned statically by a plurality of keys and being distributed to a plurality of information processing devices on a key-region-by-key-region basis; setting an address that is a network address identifying a communication endpoint in a communication network and that is statically associated with the first key region to configuration information of a network interface included in the computer, according to association information that is static information and that indicates statically determined association of each of the plurality of key regions of the database with a plurality of network addresses identifying a plurality of communication endpoints in the communication network, the setting being dynamically performed in response to the assignment instruction, the plurality of communication endpoints being located at the plurality of information processing devices in the communication network; transmitting a message in which one of the plurality of network addresses of the plurality of communication endpoints associated with a target key region which is one of the plurality of key regions is specified as a destination; monitoring a reply to the message; and recognizing occurrence of a failure in a first other computer which is one of the plurality of information processing devices and to which the network address specified as the destination is set, when the reply is not returned within a predetermined time period.
