Information processing system capable of enabling cooperation of processing when connection with external apparatus being disconnected, information processing apparatus therefor, and non-transitory computer readable medium storing program therefor

An information processing system comprising:

• an information processing apparatus;
• and
• a server,
• wherein the information processing apparatus transmits data to be processed to the server as a first job, makes an inquiry about whether or not processing is completed to the server, and waits for a response from the server, wherein the information processing apparatus is configured to:
• make the inquiry to the server by long polling in a case that the server cannot access the image processing apparatus;
• in a case where a response indicating that the processing by the server is completed is received in response to the inquiry, acquires data of a processing result for the data to be processed, which is transmitted to the server in the first job, as a second job different from the first job, and
• in a case where a connection between the information processing apparatus and the server is disconnected before or during the execution of the second job, makes the inquiry about whether or not the processing is completed to the server again and waits for a response from the server, and the server
• acquires the data to be processed from the information processing apparatus and executes processing for the data,
• makes the response indicating that the processing is completed in response to the inquiry from the information processing apparatus, and
• transmits the data of the processing result to the information processing apparatus on a request from the information processing apparatus after the response.

A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:

• performing connection to an external server that can be connected from the information processing apparatus, transmitting data to be processed to the external server as a first job, and instructing the external server to execute processing of the first job, and then releasing a resource used in the first job;
• making an inquiry about whether or not the processing is completed to the external server, and waiting for a response from the external server, wherein making the inquiry to the external server by long polling in a case that the external server cannot access the image processing apparatus;
• in a case where a response indicating that the processing by the external server is completed is received in response to the inquiry, executing a second job to acquire data of a processing result for the data to be processed, which is transmitted to the external server in the first job, wherein the second job is different from the first job and is cooperated with the first job;
• and
• in a case where a connection between the information processing apparatus and the external server is disconnected before or during the execution of the second job, making the inquiry about whether or not the processing is completed to the external server again and waiting for a response from the external server.
