摘要

A computer includes a memory that stores a program and received data; and a processor that executes an operation by executing the program stored in the memory, the operation including storing the received data into a first database having a first data structure in which reading is performed in a random access manner and writing is performed in a sequential access manner, when the received data is received from a second apparatus is as same as data stored in a first apparatus which has a failure, and copying the received data stored in the first database to a second database having a second data structure in which reading is performed in a sequential access manner and writing is performed in a random access manner.

主权项

1. A computer comprising:
a memory; and a processor coupled to the memory and configured to:
when a first apparatus fails and data, which is same as data that has been stored in the failed first apparatus, is received from a second apparatus, store the received data into a first database having a first data structure in which reading is performed in a random access manner and writing is performed in a sequential access manner; andcopy the received data stored in the first database to a second database having a second data structure in which reading is performed in a sequential access manner and writing is performed in a random access manner,wherein the processor is further configured to:
upon reception of an update request including new data to update a specified piece of the received data that is stored in the first database and that has not been copied to the second database, write the new data with which the specified piece of the received data is to be updated into the second database; anddelete the specified piece of the received data stored in the first database.
