When a workload is created in SLES 11, it is assigned to one of the following workload management methods:

Tactical
Manages high-priority, critical queries with a short response-time requirement.
SLG Tier
Allocates resources according to the SLG tier on which the workload resides. Multiple tiers can be prioritized so higher-level tiers have higher resource allocation. This method is not used in systems with an IWM license.
Timeshare
Assigns the following access levels that indicate the priority of resource allocation:
Low
This is the baseline and lowest resource access rate for the Timeshare access method.
Medium
Queries are given an access rate 2 times the Low access level.
High
Queries are given an access rate 4 times the Low access level.
Top
Queries are given an access rate 8 times the Low access level.
