EXTENDING THE RECOVERY AND REPORTING RANGES OF OBJECTS

摘要

The reporting and recovery of log activity in a computer system is extended by receiving an indication of a desired log activity to be retrieved, and by designating an active index file as a current index file. The current index file includes an inventory of log files, and is constrained in the number of log files. A searching operation is performed in an iterative process. The searching operation determines whether the desired log activity is within any of log files of the current file, designates a backup index file as the current index file if it is determined that the desired log activity is not within the current index file, and accesses a select log file within the current index file that includes the desired log activity, if it is determined that the desired log activity is within the current index file.
