- Cheryl Watson's
- Cheryl's Advice - The warnings, advice and recommendations created by Cheryl regarding goal mode best practices appear automatically in GoalTender reports whenever conditions arise to trigger them. Taken as a whole, they comprise some of the most thorough goal mode documentation available anywhere.
What is GoalTender?
Cheryl Watson's GoalTender™ helps you manage WLM goal
mode. It implements Cheryl's WLM analysis methods and shows her recommendations
for tuning your service definitions, and through them, your sysplex performance.
How does GoalTender Work?
GoalTender is composed of two parts. The first
part is Cheryl Watson's Tracker™, a started task that runs continuously
on all systems. Tracker collects and maintains a database of WLM service
definitions, WLM service policies, certain operator actions, and SMF type
70 and 72 data.
GoalTender is a batch job that uses this data to produce a series of reports, along with extensive recommendations developed from hundreds of real-life tuning experiences.
What will GoalTender Show me?
- Exception Reports
- Summary Report - This summarizes the activity for the analysis period (e.g. the last 24 hours) to quickly show you the most critical items -- the three most active intervals and the three intervals with the worst goal performance.
- Interval Report - This report provides an in-depth look at selected intervals, showing how each service class period performed and the probable reasons for any underperformance.
- Missed Goals Report - This report shows missed goals for the entire analysis period as well as many other conditions needing your attention, and can be sorted by time and/or importance. Again, our advice will tell you why your system is performing badly and what you might do about it.
- Other Useful Reports
- Service Definition Report - This is an annotated listing of your service definitions and policies, along with Cheryl's suggestions, if any, for improvement.
- Servers Report - This shows which service classes are being used as servers and which are being served, as well as the volume of activity.
- Importance Report - This shows the amount of work at each importance level and whether lower priority work is getting squeezed out by higher importance work.
- Tracker Log- This log shows the contents of Tracker's database of policies, events and SMF data. You can tell, for instance, when policies were activated or when an operator changed a job's service class.
GoalTender and Tracker are written in IBM Assembler language and require only that you be in goal mode and at OS/390 V2R10 or later.
