Logical problem determination for SNA networks

Problem determination on a Systems Network Architecture network has dealt mostly with error detection on physical network components. Adequate logical error-detection mechanisms associated with the logical network (software-related) errors have been only recently provided with the announcement of a new on-line interactive package called the Network Logical Data Manager (NLDM). This paper discusses the physical and logical network environments, logical network problems, and functions provided by the two releases of NLDM for logical problem determination.
