Teradata Active System Management (TASM ) and its Functions

• It is made up of several products/tools that assist the DBA or application developer in defining and refining the rules that control the allocation of resources to workloads running on a system.
• These rules include filters, throttles, and workload definitions.

TASM is an enhanced compilation of three core products consisting of the following:

• Teradata Dynamic Workload Manager(TDWM)- Manages And Monitors Workload Strategies
• Teradata Manager- Analyzes Historical Workloads
• Teradata Workload Analyzer (TWA)-Analyzes and Recommended Candidate Workloads.

 TASM  allows User to perform the following:

o   Limit User Concurrent Access

o   Monitor Service Level Goals

o   Determine the Workload on A System

o   Prioritize and Optimize Mixed Workloads

o   Block or Reject User Queries Based on Table Access

o   Provide Consistent Response Times

o   React to Hardware Failures.

• When utilized together, these tools can monitor workloads in real time along with providing historical reports based on resource utilization by workload.
• By analyzing this detailed information, workload definition can be modified to improve query performance, and resource allocation.
