CHAPTER 2
System Tools and Architecture
Viewpoint Workload Designer
The Viewpoint Workload Designer portlet enables users to create rules for managing the system workload.
Teradata Dynamic Workload Manager
Teradata Dynamic Workload Manager (TDWM) consists of code within Teradata Database to manage incoming work according to user-created rules. The core of TDWM is in the
Dispatcher portion of the DBS.
Viewpoint Workload Monitor
The Viewpoint Workload Monitor portlet enables users to monitor workload activity in
Teradata Database.
Viewpoint Workload Health
The Viewpoint Workload Health portlet displays workload management activity in Teradata
Database for one system at a time and enables users to monitor the status of individual workloads.
PM/APIs and Open APIs
PM/APIs and open APIs (also called SQL interfaces) provide CLIV2 and SQL functions to access workload management and system information. Performance Monitor and
Production Control (PMPC) data is collected internally and used to monitor workload management events. Several Viewpoint portlets use PM/APIs to monitor system activity. For more information on PM/APIs and open APIs, see Application Programming Reference,
B035-1090.
