Abstract

An on-line system having a plurality of terminal equipments and host computers connectable to the terminal equipments, each host computer responsive to a job request from a terminal equipment being provided with an on-line process for transferring the control of the job request to a job execution process determined in accordance with the content of the job request, and a plurality of regular job execution processes for executing, if the job request is a regular job request, a regular job for the regular job request. The on-line control process is provided with an irregular job execution process space generating process for generating an irregular job execution process space for the irregular job execution. The irregular job execution process space generating process generates an irregular job execution process space upon the irregular job request from the terminal equipment, and calls an irregular job execution process request program for the irregular job request in the irregular job execution process space to execute an irregular job for the irregular job request.

Claims

1. An on-line system for executing jobs, wherein said system mainly executes a job being defined as a regular job which includes, a transaction process, said system comprising:

a plurality of terminal equipments each including means for discriminating whether a request given by a user is for execution of a regular job mainly executed by said system or execution of a job other than said regular job, said job other than said regular job being defined as an irregular job which includes, an interactive process defined as a time sharing system, said means for discriminating generates a regular job request or an irregular job request based on said discrimination; and

a plurality of host computers connectable to said plurality of terminal equipments, each host computer responsive to a job request from a terminal equipment being provided with an on-line control process for transferring the control of said job request to a job execution process determined in accordance with the content of said job request, and a plurality of regular job execution processes each executing, if said job request is a regular job request, a regular job for a regular job request whose control was transferred from said on-line control process;

wherein said on-line control process is provided with irregular job execution process space generating means for generating an irregular job execution process space, said irregular job execution process space generating means generates an irregular job execution process space based upon said irregular job request from said terminal equipment, and calls an irregular job execution process request program for said irregular job request in said irregular job execution process space to execute an irregular job for said irregular job request.

2. An on-line system for executing jobs, wherein said system mainly executes a job being defined as a regular job which includes, a transaction process, said system comprising:

a plurality of terminal equipments each including means for discriminating whether a request given by a user is for execution of a regular job mainly executed by said system or execution of a job other than said required job, said job other than said regular job being defined as an irregular job which includes, an interactive process defined as a time sharing system, said means for discriminating generates a regular job request or an irregular job request based on said discrimination; and

a plurality of host computers connectable to said plurality of terminal equipments, each host computer responsive to a job request from a terminal equipment being provided with an on-line control process for transferring the control of said job request to a job execution process determined in accordance with the content of said job request, and a plurality of regular job execution processes each executing, if said job request is a regular job request, a regular job for a regular job request whose control was transferred from said on-line control process;

wherein said on-line control process is provided with irregular job execution process space generating means for generating an irregular job execution process space;

wherein a predetermined number of irregular job execution process spaces are provided beforehand in each of said host computers by said irregular job execution process space generating means, and each host computer is provided with irregular job execution process space controlling means for supervising the status of said irregular job execution process spaces; and

wherein if said irregular job request is made from said terminal equipment, said irregular job execution process space controlling means assigns an irregular job execution process space to said irregular job request, and calls an irregular job execution process request program in said assigned irregular job execution process space to execute an irregular job for said irregular job request.
