Or if you have one of the latest Linux versions you can specify memory with a startvalue and a maxvalue giving room for adding memory on the fly. Use lsmem to see if it is possible. Add more with chmem -e 256 or any multiple of 256, it also must be available of course. NOTE! Do NOT use chmem -d nnn to remove memory, that is not safe (yet)

Expand it? No. But the norm (for Linux on any HW) is to add more swap volumes, not enlarge them. This can be done on-the-fly. Remember to make it permanent ... if the need is expected to persist. (Or remember to enlarge what you run through SWAPGEN.) For VDISK, create another with 'vmcp define', then bring it online with 'chccwdev -e', then 'mkswap' against the new device, and then 'swapon' that same device. This is not permanent. If you are in a crisis (any HW), you can use a file for swap. Again 'mkswap' and then 'swapon'.
