Determining Workload Management Needs. Teradata Release 15.10 User Guide

CHAPTER 3

Preparing to Implement Workload Management

Determining Workload Management Needs

Take the following actions before implementing workload management.

Action

Monitor single system metrics and resource usage trends within specified time frames with the Viewpoint Metric Heatmap portlet.

Study resource contention at various times of day and to understand blocking and wait time patterns with the Viewpoint Query Monitor and

Lock Viewer portlets.

Enable DBQL detailed logging for at least 3 weeks to understand request performance.

• Capture DBQLogTbl, DBQLSQLTbl, and

DBQLObjTbl data.

• After detailed logging captures enough information, use the LIMIT THRESHOLD or

LIMIT SUMMARY options for highly-tuned short work.

Enable Resusage.

Additional Information

For information on the Metric Heatmap portlet, see Teradata Viewpoint User Guide, B035-2206.

For more information on the Query Monitor and Lock Viewer portlets, see Teradata Viewpoint

User Guide, B035-2206.

ResSPMA, ResSPS, and ResSAWT are extremely helpful with system, scheduler, and AMP Worker

Task (AWT) analysis.

The ResUsageSPS table can help you determine resource usage by performance group.

Identify workload types, such as ad hoc, ETL, and short highly-tuned requests:

• Determine how these workloads are identified on the system; for example, by account strings, profiles, and groups of users.

• Identify different processing periods, such as day, night, weekday, and weekend.

• Determine the priorities given to different workload types during different processing periods.

Document all Service Level Goals.
