Abstract

The invention's method newly provides "SEGMENT I/O PROBABILITY REPORT" in IMS High Performance Pointer Checker for OS/390(HPPC). The report shows the probability of doing I/O (PROB. OF IO) when traversing from any segment type to another segment type. The distinctive feature of the report is showing the probabilities in a hierarchical format. The hierarchical format emphasizes which points have high possibilities that occur I/O. as appropriate)? HPPC monitors the performance and consistency of IMS hierarchical data base. HPPC has shown PROB. OF IO in a Segment Pointer Statistics Report (shown in Figure 1). The PROB. OF IO is on rightmost field in Figure 1.
