If you need to recreate a swap file, you can follow this step as root user:
dd if=/dev/zero of=/var/swap bs=$((1024*1024)) count=100 # 100MiB swap file
mkswap /var/swap
(supposing that /var/swap was a file used for swap)
For activate it:
swapon /var/swap
For checking swap usage, you can:
cat /proc/swaps
If you need to make some more ram available, and you don't want to use swap, you can use zram:
