METHOD FOR REORGANIZATION MANAGEMENT IN A SET OF INDEXED DATABASES OF A COMPUTER SYSTEM

摘要

The invention concerns an offline reorganization management in a set of indexed databases, in particular of the tablespace type, of an information computer system comprising the following steps: (10): continuously maintaining a list (PRIOREORG) of objects to be reorganized in descending order of priority; (20) executing a process (IDPOR) of identification of the next object to be reorganized (POR) in the absence of any reappraisal event (RAZ) and comprising the following steps: (21) establishing a rapid reorganization planning (PRR) using the list (PRIOREORG) and residual operational time (TRR) and a selection list (SELECT) of objects (OR); (22) establishing reorganization retroactive planning with LIFO memory storage of objects extracted from the list (SELECT); (23) identifying the available processing zone (RTR) to reorganize the object (POR); (24) writing (POR) when the zone (RTR) is cleared in the absence of any event (RAZ); and re-executing the process (IDPOR).
