System and method for analyzing a database for on-line reorganization

摘要

An improved method and system for analyzing a database for determining a recommended reorganization of a database. In one embodiment, the method involves receiving a list of database records to be analyzed. Each analyzed database record which meets certain criteria may be designated as “qualified”. Identifying information for each qualified database record may be added to a detail array. The qualified database record information may be aggregated based on information in the detail array. The process of aggregating the qualified database record information may include constructing additional arrays (e.g., a roll-up array and a results tracking array). A reorganization strategy may be recommended based on the aggregated qualified database record information. The recommended reorganization strategy may be for an amount (e.g., none, full, partial) of reorganization of the database and a method (e.g., off-line, concurrent, on-line) of reorganization of the database. The recommended reorganization strategy may be implemented.
