PURPOSE: To arrange and integrate debugging results of multiple processes so as to obtain a consistent debugging result by integrating transaction processing debugging information randomly registered by means of a registering means to series of transaction process debugging output information.

CONSTITUTION: At the time of transaction (TX) process debugging, a TX identifier is handed to a debugging information registering form discriminating means 1 from a debugging process. The means 1 retrieves a discriminating table, the content of which that is previously designated at the time of system preparation is dynamically updated by means of a dynamically changing means 4 by using the TX identifier and job identifier inputted from a console, by using the TX identifier as a key and obtains a relevant X. Then the means 1 adds the job identifier and a process number to the debugging information and actuates a registering means 2 being followed by the information. The means 2 performs automatic preparation of a sub-file and decides the destination of the sub-file based on the sub-file index of the TX. The means 2 then registers the debugging information in the destination and a TX unit retrieval coupling means 3 arranges and integrates debugging results.
