Vantage consumes high CPU.  How to customize Vantage without losing information quality?

Resolution

Change Vantage service class. After you change the VANTAGE started task from a reasonably high priority address space to a low priority DISCRETIONARY address space, VANTAGE will only now use CPU when no other address space needs it. Theoretically, this will avoid any impact for other jobs and stcs. This will increase your scripts to have an excellent collection.

Discretionary: WLM-defined goal. Work is run when system resources are available. The performance index of the discretionary goal is always equal to 0.81 and has a fixed I/O priority of 248. It is the goal of the SYSOTHER Service Class. Associate this goal with work for which you do not have a specific performance goal.

If Vantage was associated Service Classes has a discretionary goal, WLM achieves the Minimum capacity only if this action does not impact other goals.
