Problem on Creating a Swapfile for adding swap space
Folks,
Hello. I am using Oracle Linux 5.6. At this time, the Linux swap space is 0 KB by using the command:
[root@rac1 /]# grep SwapTotal /proc/meminfo
I need 150MB swap space to install Oracle Database. I create the swap space using the following commands:
Step 1:
[root@rac1 /]# dd if=/dev/zero of=/swapfile bs=1024 count15360 hit enter
Output: 153600 to records in
153600 to records out
157286400 bytes(157MB) copied, 3.3835 seconds, 46.5MB/s.
Step 2:
[root@rac1 /]# mkswap /swapfile hit enter
Output: Command not found.
Step 3:
[root@rac1 /]# swapon /swapfile hit enter
Output: Command not found.
Step 4:
[root@rac1 etc]#vi fstab
Add this line into the file: /swapfile swap swap defaults 0 0
Save and close the file fstab.
Step 5:
Reboot Oracle Linux 5.6 and run this command:
[root@rac1 /]# grep SwapTotal /pro/meminfo
Output: SwapTotal: 0 KB
As you see above, swap space is not added. I think the problem is that the commands "mkswap /swapfile" and "swapon /swapfile" are not executed.
My question is : Do any folk understand how to add the swap space successfully ?
