Usable buffer-pool frames

Worked examples, recomputed

Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.

• 1,000,000 − 80,000 − 150,000 = 770,000 usable

Where it appears

Each mechanism states it in its own names. The general symbol each name stands for is shown with it.

• Memory & Resource Management

  Who is allowed to hold how much memory, for how long, and what happens to the work when the answer is less than it asked for?

  $$\text{usable frames}=\text{total}-\text{pinned}-\text{dirty}$$
