Server device operating in response to received request

A method for causing a server device to perform processing in response to a request received from a client device, the method comprising the steps of:

• retrieving, by an identification information storage unit of the server, at least one request waiting to be processed from a request storage region within a system memory space on condition that the number of identification information pieces stored in the identification information storage region has declined to a predetermined reference number or below;
• storing identification information of the retrieved request in the an identification information storage region within a user memory space wherein the identification information identifies a connection to receive the retrieved request;
• operating a plurality of request processors of the server device in parallel, to acquire from the request storage region the request identified by the identification information on condition that identification information has been acquired from the identification information storage region;
• processing the required request;
• and
• storing a state of the identification information storage region, in a state storage region in user memory space, based on at least one of the numbers of identification information pieces stored in the identification information storage region and of identification information pieces acquired from the identification information storage region, wherein
• upon newly storing identification information in the identification information storage region, the identification information storage unit updates the state stored in the state storage region according to the number of the identification information pieces newly stored,
• upon acquisition of identification information from the identification information storage region, the request processor updates the state stored in the state storage region according to the number of the acquired identification information and determines, according to the updated state, whether or not the number of identification information pieces stored in the identification information storage region has declined to the reference number or below, and
• the condition that a number of identification information pieces stored in the identification information storage region has declined to a predetermined reference number or below is checked by at least one of the request processors by (i) counting the identification information storage region by scanning the number of identification information pieces or (ii) accessing the state storage region and referring to a counter which counts the number of identification information pieces in the identification information storage region.

A computer program product for causing a server device to perform processing in response to a request received from a client device, the computer program product comprising:

• a non-transitory computer readable medium tangibly embodying program instructions having computer readable instructions which when implemented, cause a computer to carry out the steps of a method comprising;
• retrieving at least one request waiting to be processed from the request storage region within a system memory space on condition that the number of identification information pieces stored in the identification information storage region has declined to a predetermined reference number or below;
• storing identification information of the retrieved request in the identification information storage region within a user memory space wherein the identification information identifies a connection to receive the retrieved request;
• operating a plurality of request processors of the server device in parallel, to acquire from the request storage region the request identified by the identification information on condition that identification information has been acquired from the identification information storage region;
• processing the acquired request, and
• storing a state of the identification information storage region, in a state storage region in user memory space, based on at least one of the numbers of identification information pieces stored in the identification information storage region and of identification information pieces acquired from the identification information storage region, wherein
• upon newly storing identification information in the identification information storage region, the identification information storage unit updates the state stored in the state storage region according to the number of the identification information pieces newly stored,
• upon acquisition of identification information from the identification information storage region, the request processor updates the state stored in the state storage region according to the number of the acquired identification information and determines, according to the updated state, whether or not the number of identification information pieces stored in the identification information storage region has declined to the reference number or below, and
• wherein the condition that the number of identification information pieces stored in the identification information storage region has declined to a predetermined reference number or below is checked by at least one of the request processors by (i) counting the identification information storage region by scanning the number of identification information pieces or (ii) accessing the state storage region and referring to a counter which counts the number of identification information pieces in the identification information storage region.
