This article describes a technique for storing trace data during a communication session. It has particular value for devices with limited trace storage capability. The technique calls for two memories and the storing of all control commands in one of the memories during the session. The trace is stored in the other memory. This technique enables the trace to be viewed in the context of all control information issued prior to the start of the stored trace data. The steps of the method are as follows: 1. Provide for automatic termination of the trace after a prespecified number of events. (An event is defined as either a Systems Network Architecture (SNA) request or response command.) In this fashion, the trace is stopped to provide specific data for diagnosis of the communications problem.
