8장. Swap
System의 물리적인 partition을 변경하지 않고 swap size를 늘리고자 하는 방법.
* Sun OS(Solaris 1.x)
# pstat –s; swap space 확인
# mkfile -nv 40m /home/swapfile; swap file 생성
# /usr/etc/swapon /home/swapfile; swap space 확장
# pstat -s or -T; swap space 확인
- booting시 자동 swap on 하려면 아래 file edit
# vi /etc/fstab
/home/swapfile swap swap rw 0 0
- swap_on 한 작업을 최소 하려면
# rm /home/swapfile
# vi /etc/fstab 하여 추가했던 entry 삭제
* Solaris 2.x
# pstat -s; swap space 확인
# /usr/sbin/mkfile -nv 40m /home/swapfile; swap file 생성
# swap -a /home/swapfile; swap 공간 확장
# pstat -s or swap -s; total swap_size 확인
- booting시 자동 swap on 하려면 아래 file edit
# vi /etc/vfstab
/home/swapfile - - swap - no -
* SWAP(참조)
The swap command is used to display swap space usage, and to add or remove swap areas on
disk;
#swap –l
swapfile dev swaplo blocks free
/dev/dsk/c0t3d0s1 32,25 8 187912 127088
Creating and Adding swap areas
#mkfile 10m /exp/swap
#swap -a /exp/swap
#swap -l
swapfile dev swaplo blocks free
/dev/dsk/c0t3d0s1 32,25 8 187912 127088
/exp/swap - 8 20472 20472
Removing swap areas
#swap -d /exp/swap
