But it doesn’t have to be, thanks to GWLM!


The IBM Graphical Workload Management Tool (GWLM)

What is it?

A proof-of-concept experiment created by Kevin Beck and myself to explore

the possibilities for a more natural graphical interface for Db2 workload

management

An application written using Adobe Flex and running under Adobe Air (and

Java)

What is it intended to do?

Provide a visual overview of a workload management (WLM) configuration to

show at a glance how work is categorized and controlled

Allow you to explore and manipulate the details of the individual WLM entities

in an intuitive manner

Make all our (WLM) lives easier


What else you need to know about GWLM

It is provided free, as-is for your use and exploration

Support is on a best-efforts basis by me, myself, and I

• Actual personnel will vary based on demands of my “day job”

Important Legal words:

This tool is not an official product nor does it represent any commitment by

IBM to actually implement or provide a product such as this to the general

public at a later date.

Known limitations

Print and Generate PDF options are fairly crude The print capability is limited to the currently displayed screen

The Generate PDF option produce a series of vertical screen images and does not compensate for configurations that exceed the display screen horizontally

To minimize the impact of these limitations, you can reduce the size of the displayed image using the zoom slider

Functional limitations Comments for any workload objects are not shown and cannot be added.

Workload usage privileges are not modeled

Support for statement thresholds is limited: • No ability to modify statement text

• No ability to create new statement text thresholds

• No support for generation of delta DDL

Display limitations Disabled or unused work action sets are not hidden.

A few other minor anomalies


To give GWLM a try !!
