I have some sensitive data in RAM that I prefer not to be on disk. How do I disable swap?
I have more than enough RAM. If RAM consumption gets too high I have no problems with processes being terminated. How do I disable swap?
Note: I do not have a swap partition and this is running in a VM (VMware)
I have, by default, 250MB of swap space in Ubuntu, and I want to expand it to a larger size. I need 800MB, which I think will be enough to open several applications without having to hit the current limit of swap. I hope someone can help me.
I need a step-by-step, simple and easy way to configure swappiness.
I did not create a swap partition during Ubuntu installation. Later, I freed up some space and made a swap partition. Now after each boot up, I am manually opening gparted to right-click the swap partition to turn on the 'swapon' option.
How can I automatically enable the swap partition at boot?
Also, if I had not created the swap partition, what are my other options?
When I open a RAM-intensive app (VirtualBox set at 2GB of RAM), some swap space is generally used, depending on what else I have open at the time.
However, when I quit that last application, the 2GB of RAM is freed up, but the same swap space use remains.
For example, right now, about two hours after having closed VirtualBox, I have 1.6GB free RAM and still 770MB in swap.
How can I tell Ubuntu to stop using that swap and to revert to using the RAM?
