Abstract

PURPOSE:To collect information extending over many hours by collecting the communication control information between a transmission procedure control part of a pre- communication processor and a line control part of a communication control equipment, in accordance with an instruction from a host computer, and transferring said information to the host computer. CONSTITUTION:When a command for obtaining a trace is given, a communication trace program collects communication control information used for an input/output request and its completion notice between a transmission procedure control part 21 and a line control part 71, and stores it in a designate area of a main storage device of a pre-communication processor 2. When the designated area for storing the communication control information which has been collected overflows, the communication trace program obtains a transfer use buffer for transferring the communication control information to a host computer system, stores the collected communication control information in a buffer for transfer and starts a transfer tank. The transfer task transfers the information to the host computer system 1 by using the buffer for transfer to which a transfer request has been given from the communication trace program, and ends its task by releasing its transfer use buffer.

In the conventional communication tracing method of the front-end communication processing unit, the collected communication control information is stored in the main memory of the front-end communication processing unit, so in order to obtain the collected information, the front-end communication processing unit must be connected. It is necessary to temporarily stop and read the contents of the main memory of the front-end communication processing device. Further, the area for storing this information is limited, and when that area exceeds 70-, it is used for the buik click, so the previously collected communication control information is destroyed and new information is stored. In other words, it has the disadvantage that information cannot be collected over a long period of time.
