Abstract

A method is described which allows generic compacted data in a computer system's error or trace log to be formatted into a readable and intelligible form. Computer system error and trace logs are diagnostic tools which permit storing of important system data in the event of a serious error or during system performance analysis. They typically consist of programs which save or store important system data, storage devices which contain said data, and programs which interpret or format this data. They must operate in a wide variety of environments and with a wide variety of data. Since they are used to diagnose "abnormal" situations, they must perform in the most unobtrusive manner possible.

Table-Driven Report Formatter for Packed Error or Trace Data

A method is described which allows generic compacted data in a computer system's error or trace log to be formatted into a readable and intelligible form. Computer system error and trace logs are diagnostic tools which permit storing of important system data in the event of a serious error or during system performance analysis. They typically consist of programs which save or store important system data, storage devices which contain said data, and programs which interpret or format this data. They must operate in a wide variety of environments and with a wide variety of data. Since they are used to diagnose "abnormal" situations, they must perform in the most unobtrusive manner possible. Thus, error and trace log data must be compacted to achieve the most efficient storage of said data (in terms of speed and space needed) and the least impact on the function of the system as a whole. Due to the fact that the programs must deal with data from a great variety of programs and hardware devices, interpretation of the data can be very complicated. The programs to store and format these data must be very specialized and dependent on the conformation of the system's hardware and software. Since the system may change significantly over its life as a product, the data stored by the programs may become obsolete. Changing the hardware or software in the system necessitates costly and time-consuming programming efforts in order to keep the error logging and trace programs current. For machines designed to operate with a minimum of direct after-sale support (such as microcomputer), the user of the machine might well be totally unable to make such changes. These problems adversely affect the reliability, availability, and serviceability (RAS) of the computer. In accordance with the new method in order to mak...
