Increase swap memory in Solaris 11
Firstly, check where your swap file is, If it is a ZFS volume
created during the Solaris installation then follow below steps:
# top -d1 | grep -i "total swap"
Memory: 126G phys mem, 93G free mem, 4096M total swap, 4095M free swap
# swap -l
swapfile dev swaplo blocks free
/dev/zvol/dsk/rpool/swap 248,1 16 33554416 33554416
# zfs get volsize rpool/swap
NAME PROPERTY VALUE SOURCE
rpool/swap volsize 4G localNow you need to unmount it. (disable swap memory)
# swap -d /dev/zvol/dsk/rpool/swapYou can check it is unmounted or not. It should return as
"No swap devices configured".
# swap -lSet swap memory as per requirement. (It's a ZFS volume and you
just need to resize it)
# zfs set volsize=16G rpool/swapAnd then add it back into your swap space:
# swap -a /dev/zvol/dsk/rpool/swapNow check swap memory increased:
# swap -l
# zfs get volsize rpool/swap
# top -d1 | grep -i "total swap"
