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.

主权项

1. In a computer system, a machine-executable method for extending the reporting range of log activity, the method comprising:
receiving an indication of a desired log activity to be retrieved; designating an active index file that is utilized by the computer system, as a current index file, wherein the current index file includes an inventory of log files, and the current index file is constrained in the number of log files therein; and performing a searching operation in an iterative process until a predetermined stopping condition is met, the searching operation including:
determining whether the desired log activity is within any of the log files of the current index file;performing, if the determination indicates that the desired log activity is not within the current index file, an operation to obtain a new index file by:
selecting one of the log files in the inventory of log files of the current index file;determining a backup index file that was created when the selected one of the log files was added to the active index file at some historical point; anddesignating the backup index file as a new instance of the current index file, andaccessing 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, and designating the predetermined stopping condition satisfied.
