The Configuration Trace Report (shown in Figure 3-2) provides a concise and effective reporting of the hardware configuration activity, starting with the hardware configuration at the time of IPL and continuing to the current time. It contains a precise tracing of the configuration at IPL and itemizes each device action (for example, VARY CHANNEL ON) that has taken place since the IPL. The report is particularly effective in resolving performance and availability problems caused by improper system configuration. The Operations Configuration File (OPSCON) in the Operations Information Area maintains a record for every device that was on the system at IPL and for every allocation and vary action. The reporting process prints out the contents of these records based on user-specified selection criteria. The reporting program puts the incident and configuration records into a report that condenses the records into an easy-to-read and useful report. For example, the IPL Configuration records are listed by device type, with sequential addresses represented by the first and last address of each sequence. Thus, if the report finds 3390 disks on addresses 981, 983, 984, 985, and 986, it will print 'DASD 3390: 981 983-986'. A separate report is printed for each SYSID in the file. Each page heading gives the SYSID and the date of the first record. Every date change is printed in the time column and every hour change is separated by a dashed line. A report printed with the system defaults starts reporting at the time of the last IPL and continues to the end of the file. The first page or two show the conditions at the time of the IPL and succeeding pages show changes to the initial conditions. A close look at this information shows the system configuration for any point in time.
