Database control method, database control apparatus, and recording medium

A control apparatus, comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• generate a second database in which recorded contents of a first database are copied, when detecting an update program used to update a first control program configured to control the first database set as a transmission destination of a request for processing transmitted by a terminal apparatus,
• generate a second control program by updating the first control program using the update program,
• set the transmission destination of the request to both the first database and the second database,
• execute the processing on the first database using the first control program,
• execute the processing on the second database using the second control program,
• set the transmission destination to only the second database among the first database and the second database, when a first result of the processing on the first database and a second result of the processing on the second database match, and
• execute processing on the second database using the second control program when receiving the request from the terminal apparatus.

A non-transitory computer-readable recording medium storing a program that causes a processor included in a control apparatus coupled to a terminal apparatus to execute a process, the process comprising:

• generating a second database in which a recorded content of a first database are copied, when detecting an update program used to update a first control program configured to control the first database set as a transmission destination of a request for processing transmitted by the terminal apparatus;
• generating a second control program by updating the first control program using the update program;
• setting the transmission destination of the request to both the first database and the second database;
• executing the processing on the first database using the first control program;
• executing the processing on the second database using the second control program;
• setting the transmission destination to only the second database among the first database and the second database, when a first result of the processing on the first database and a second result of the processing on the second database match;
• and
• executing processing on the second database using the second control program when receiving the request from the terminal apparatus.
