Infrastructure Software

Hi,

I am a newbie in installing linux. I installed Oracle Linux 5 successfully. I selected all default options while installing.

[root@localhost mapper]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 230634360 3279712 215450036 2% /
/dev/sda1 101086 23390 72477 25% /boot
tmpfs 1942200 0 1942200 0% /dev/shm

I did a remount of the shared memory to 4GB

[root@localhost mapper]# mount -o remount,size=4G /dev/shm
[root@localhost mapper]# df -l
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 230634360 3279916 215449832 2% /
/dev/sda1 101086 23390 72477 25% /boot
tmpfs 4194304 0 4194304 0% /dev/shm

Is this correct way to increase swap to 4GB? I have 4GB RAM in my machine.

Also out of that 250 GB in /, I want to create partitons like /db for 100GB & /data for 100GB.
Can you guys please help me with the command to do this resizing?

[root@localhost /]# fdisk -l
