The Pre-Migration Tool uses a mapping scheme to assign timeshare workloads one of four access level values based on allocation group relative weight values in SLES 10.
|SLES 10 Allocation Group Relative Weight||SLES 11 Access Level|
|> 5% to 10%||High|
|> 2% to 5%||Medium|
|0 to 2%||Low|
Access level affects access rate (that is, resource volume received by a query) at a ratio of 2:1. So queries running in a timeshare workload of a given access level receive twice the resource volume as queries running in a timeshare workload of the access level immediately below.
|Access Level||Access Rate|
Use the Pre-Migration tool to change the access level value automatically assigned to each timeshare workload for each planned environment, if necessary to meet priority-scheduling goals. To minimize required changes to individual workload access level values, adjust the mapping scheme of relative weight values to access level values for each planned environment as a first step.
