Abstract

A server apparatus includes a reception unit that receives, from a client apparatus, an updated data acquisition request for acquisition of updated data on setting information about the client apparatus that is stored in a non-volatile storage device of the server apparatus, a generation unit that generates data indicating that the updated data does not exist without accessing the non-volatile storage device in a case where identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in an identification information list of a client to which an updated data response has been transmitted, the identification information list being stored in a cache memory, and a response unit that transmits to the client apparatus a response with the generated data indicating that the updated data does not exist.

Claims15

Dependent claims

A server apparatus comprising:

a memory device that stores a set of instructions;
and
at least one processor that executes the set of instructions to:
acquire a request for updating setting information;
update, based on the request, the setting information stored in a nonvolatile storage device of the server apparatus;
delete identification information for identifying a client apparatus from an identification information list in a case where the setting information stored in the nonvolatile storage device of the server apparatus is updated;
receive, from a client apparatus, an updated data acquisition request for acquisition of the updated data on the setting information about the client apparatus that is stored in the non-volatile storage device of the server apparatus;
determine whether or not identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in the identification information list;
transmit, to the client apparatus, a first response indicating that the updated data does not exist without accessing the non-volatile storage device in a case where it is determined that the identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in the identification information list;
transmit, to the client apparatus, a second response including updated data obtained by accessing the non-volatile storage device in a case where it is determined that the identification information for identifying the client apparatus that transmitted the updated data acquisition request is not included in the identification information list;
and
add the identification information for identifying the client apparatus that transmitted the updated data acquisition request for the updated data stored in the non-volatile storage device of the server apparatus to the identification information list in a case where the second response is transmitted.

9 more elements

An information processing method executed by a server apparatus, the information processing method comprising:

acquiring a request for updating setting information;
updating, based on the request, the setting information stored in a nonvolatile storage device of the server apparatus;
deleting identification information for identifying a client apparatus from an identification information list in a case where the setting information stored in the nonvolatile storage device of the server apparatus is updated;
receiving, from a client apparatus, an updated data acquisition request for acquisition of the updated data on the setting information about the client apparatus that is stored in the non-volatile storage device of the server apparatus;
determining whether or not identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in the identification information list;
transmitting, to the client apparatus, a first response indicating that the updated data does not exist without accessing the non-volatile storage device in a case where it is determined that the identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in the identification information list;
transmitting, to the client apparatus, a second response including updated data obtained by accessing the non-volatile storage device in a case where it is determined that the identification information for identifying the client apparatus that transmitted the updated data acquisition request is not included in the identification information list;
and
adding the identification information for identifying the client apparatus that transmitted the updated data acquisition request for the updated data stored in the non-volatile storage device of the server apparatus to the identification information list in a case where the second response is transmitted.

6 more elements

A non-transitory computer readable storage medium storing a program for causing a computer to execute a method executed by a server apparatus, the method comprising:

acquiring a request for updating setting information;
updating, based on the request, the setting information stored in a nonvolatile storage device of the server apparatus;
deleting identification information for identifying a client apparatus from an identification information list in a case where the setting information stored in the nonvolatile storage device of the server apparatus is updated;
receiving, from a client apparatus, an updated data acquisition request for acquisition of the updated data on the setting information about the client apparatus that is stored in the non-volatile storage device of the server apparatus;
determining whether or not identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in the identification information list;
transmitting, to the client apparatus, a first response indicating that the updated data does not exist without accessing the non-volatile storage device in a case where it is determined that the identification information for identifying the client apparatus that transmitted the updated data acquisition request is included in the identification information list;
transmitting, to the client apparatus, a second response including updated data obtained by accessing the non-volatile storage device in a case where it is determined that the identification information for identifying the client apparatus that transmitted the updated data acquisition request is not included in the identification information list;
and
adding the identification information for identifying the client apparatus that transmitted the updated data acquisition request for the updated data stored in the non-volatile storage device of the server apparatus to the identification information list in a case where the second response is transmitted.
