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!
