How big of a swap partition do I need for Linux?

In the past it was recommended that the swap space should be at least equal to the amount of RAM and should not exceed, as a rule of thumb, twice the amount of RAM depending on the amount of hard disk memory available. So if a computer’s RAM size is 128KB, a recommended swap partition would be 256KB.

How does eager swap work in Oracle Database?

Under Eager swap, as a process consumes memory, it also marks the same amount of swap space as used, so, for example, if your oracle database has 6G RAM allocated in the SGA, it will allocate both 6G RAM and 6G swap. If there is insufficient swap space, it won’t kill other processes to make space.
