RWA

Use RWA to reorganize files while applications are in use

Reorganize While Active reorganize files during business hours and doesn’t indispose users by forcing them to log off like IBM’s RGZPFM utility. Reorganizing files at user-scheduled intervals improves system performance and eliminates unnecessary DASD purchases. RWA is especially useful with large, heavily used files that take several hours to reorganize.

Real-time monitoring during the reorganization process keeps technicians informed. RWA analyzes designated files and generates a report that flags files needing reorganization. Acceptable thresholds are user defined.

Copied and reorganized files are kept synchronized to the production environment. As changes are made to files in the production environment, they are also made to the copied file in the reorganization environment. This process continues until a final file swap is performed.

The synchronized and reorganized file is then swapped with the production file in moments when no other user or process has allocation of the production file. The non-reorganized production file is either deleted or moved to another library based on command parameters.

Complete ROI often comes in one use

Configurable
RWA tells technicians which files need to be reorganized based on user defined criteria. RWA automatically identifies and lists files containing deleted records, indicating how many deleted records are in each file and how much disk space will be recovered when the file is reorganized.

Efficient
RWA reorganizes files without locking out users, therefore, files can be reorganized whenever it is advantageous to do so. Regularly reorganized files improve system performance and extend the useful life of your disk resources, postponing or eliminating unnecessary DASD expenditures.

Advanced
RWA reorganizes multiple files simultaneously, which accelerates the process. With Reorg While Active, reorgs are completed in a fraction of the time needed by RGZPFM.

Self-Diagnostic
RWA features real-time monitoring through the reorganization process. RWA can be stopped midway though a reorg, and scheduled to restart again later, so large reorgs can be done incrementally.

Complimentary
RWA is one component in a trio of iSeries disk management tools offered by S4i. DASD-Plus is a widely used disk management tool that offers more than 25 disk-clearing functions, disk usage analysis and reporting. DASD-Plus Alert delivers real-time spike detection with alerts and automated data collection and analysis.
