Teradata 15.10 TASM includes a new Priority Scheduler design for SLES11.

The old Priority Scheduler is an application for TD 15.10 SLES10.

The Priority Scheduler for SLES11 is based on constructs such as Virtual Partitions, Workload Methods, Access Levels, and Tiers.

All the features that exist in TWA 13.10 will work as is for TD 15.10, 14.10, 14.0, SLES10 (except 15.10, 15.0, 14.10, and 14.0 changes other than SLES11 Priority Scheduler.

Note the following changes when TWA 15.10 is connected to TD 14.0 and higher SLES11:

  • The Analysis > Convert PDSets to Workloads menu item is disabled. This option is supported for TD 14.0 and higher SLES11.
  • Four new default workloads exist in addition to the WD-Default workload. All four default workloads are listed in the candidate workload tree window.
  • These Default workloads are created for Timeshare workload method with access rates Top, High, Medium, and Low under the default Virtual Partition. Evaluation orders of these Workloads are in the following order:
  •

  • The RuleSet > Workload to AG mapping menu item is disabled since it is not applicable for SLES11 Priority Scheduler.
  • The Workload Attributes tab view has changed. For more details, see “Workload Attributes” on page 173.
  • A new tab has been added in the Workload Attributes tab view to define the Tactical Exception for Tactical Workload method.
  • All Tactical Workloads have a default Tactical Exception rule pair (CPU per Node and I/O per Node) set to default thresholds and are assigned a Change Workload action of WD-Default. The DBA can use the Tactical Exception workload attribute tab to change the default setting.
  • TWA 15.10 creates a default Virtual Partition name “Standard” with a quota value of 100. All the TWA recommended workloads are mapped with the default Virtual Partition. A Virtual Partition other than the default can be created by selecting Viewpoint >Workload Designer.
