VSAM is a powerful, flexible file management system and a major asset to any mainframe datacenter; however, it can also be a liability if it is not managed properly.
VSAMTune is a disk and data management software tool that allows system programmers to monitor the VSAM environment and fine tune performance to reduce CPU and disk consumption. VSAMTune also provides usage statistics to assist capacity planning and can automate many of the time-consuming tasks faced by data administrators.
System tuning
VSAMTune monitors the VSAM environment and provides expert advice on how to release valuable disk and CPU resources to save costs and increase efficiency.
Comprehensive file information
Online displays and reports highlight files and datasets that require attention.
Capacity planning
To assist with capacity planning, accurate and independent statistics for VSAM file usage are generated.
Dynamic buffer allocation
Optimum values for data and index buffer storage areas are allocated automatically to deliver additional performance gains.
Proactive tuning
Early warning features allow data administrators to optimize resource utilization, shorten batch run times and reduce pressure on the overnight processing window.
Online dataset management
A powerful online capability can be used to define, browse, edit, delete and reorganize datasets.
REXX interface
An API lets users access and manipulate VSAM datasets from REXX programs.
