Alex, 1. What about ICF processors? Do you run ICF LPARS on regular CP's? If yes, then I would strongly recommend to change it. It is strongly recomended to use dedicated processors for CF, and ICF engine is much cheaper. 2. I don't like idea to dedicate CPs for tests. IMHO t should be enough

Because there will be only 2 PCPs available for it, however, it has 8 LCPs configured. /snip No. IBM does not prevent you from defining more LP's than CP's. However the overhead becomes excessive when the LP/CP ratio exceeds (2 to 3) to 1. Actually, PR/SM does NOT allow this. If there are only

ASHARED CPs *may* be dispatched on DEDICATED processors if resource is available (I am sure someone will correct me this is not true). Assuredly. Dedicated processors are just that. Dedicated! Only the lPAR they're assigned to may run work on them, regardless of the activity. That's why I agree
