The assigned swap memory can be disabled by using swapoff command. You can list all currently mounted and active swap partition by a following linux command:
# cat /proc/swaps
Filename                                Type            Size    Used    Priority
/dev/sda6                               partition       2047996 0       -1
/swap                              file            104857596       0       -2
From the above output we can see the type of swap used, relevant file and size. The size should match the swap size output of the free or top command:
# free | grep Swap
Swap:    106905592
To disable all active swaps use -a option with swapoff:
# swapoff -a
The above will disable all active swaps found at /proc/swaps. It is also possible to disable each swap memory separately using swap file name. For example the below command will disable swap memory with a filename/swap:
# swapoff /swap
