Abstract: A test transition assistance system including the steps of: acquiring a request message and a response message from a current system by a packet capture; applying a process such as addition of an identifier and acquisition time; storing the message information in a storage; applying processes, in non-real time, such as read of the stored message information, conversion of the message corresponding to a new system, and adjustment of the time to control the number of request message transmissions per load and per unit time; transmitting a request message to the new system; receiving a response message; and comparing the old and new response messages and response times, as well as a plurality of message relations and orders, or other information. The present system reduces the number of days and man-hours and improves quality, thereby assisting in the transition of information systems from a current system to a new system.

Abstract: A rerunning load is reduced for reducing the risk of exceeding a specified termination time after abnormally ending a job net. Even if the same data processed by jobs within a job net is replaced with split data of sub-jobs and some of sub-jobs have been abnormally ended, the job net is continued. For each split data, a state and/or an execution server ID of each job are stored, and the progress of a job net is managed. Only split data whose state is not “normal” is to be processed by rerunning. Based on states of execution servers, on whether or not intermediate files transferred between jobs is shared among execution servers, and on whether or not an output file is deleted after ending the subsequent job, it is judged whether or not intermediate files can be referred to and from what job the rerun is to be performed.

Abstract: A batch job multiplex processing method which solves the problem that a system which performs multiplex processing including parallel processing on plural nodes cannot cope with a sudden increase in the volume of data to be batch-processed using a predetermined value of multiplicity, for example, in securities trading in which the number of transactions may suddenly increase on a particular day. The method dynamically determines the value of multiplicity of processing including parallel processing in execution of a batch job on plural nodes. More specifically, in the method, multiplicity is determined depending on the node status (node performance and workload) and the status of an input file for the batch job.
