DiskScope

Do you need DiskScope? Vanishing disk space ? Poor I/O performance ? No time to investigate ? No resources for solutions ? Don’t know when, where & which files are being RGZ’ed ? You NEED DiskScope !

DiskScope DiskScope - sophisticated disk space management for the iSeries

DiskScope Benefits Automatically recovers disk space Simplifies disk space monitoring Reduces disk space usage Saves effort, time and money Improves performance

DiskScope Functions Automated File Reorganization Disk Space Monitoring

Why is RGZ Neglected ? Importance is under-valued during development It is tedious to specify RGZPFM parameters for every file and member Files are added to systems but RGZ code is not included Development environments accumulate large volumes of data from batch testing but do not run clean up processes

File Reorganization Automatically recovers disk space occupied by deleted records Improves performance by reorganizing the physical sequence of records Records ordered for high performance Removes the need for special clean up processes RGZ files only when really needed

File Reorganization Features Define reorganization candidates and selection criteria Schedule reorganization Trace of reorganization results Identify candidates specifically or generically Secure files from RGZ

File RGZ Features (cont) Selection criteria based on: % deleted records space in MB used by deleted records % records Not in Key Sequence (CHAOS Factor) - unique!
