These columns represent information about the VH (Very Hot) cache, which holds the hottest permanent table cylinders.
Tables that are assigned a temperature of very hot are kept in the FSG cache as long as they:
- Stay very hot.
- Fit into the memory assigned. If the tables cannot fit, the FSG cache considers a sorted list of the hottest segments and assigns them to the very hot cache in temperature sorted order. The temperature of the segment is hot enough to qualify.
The temperature takes into account both physical and logical disk accesses and cache hits (such as, physical and logical I/Os).
