Dear all,

I am facing a problem that Oracle Universal Installer warns about swap space problem. Actually my server /tmp is more than 121 GB space.

[root@uccs ~]# df /tmp/ -h
Filesystem Size Used Avail Use% Mounted on
/dev/cciss/c0d0p5 131G 3.6G 121G 3% /

Checking available swap space requirements ...
Expected result: 48153MB
Actual Result: 8189MB
Check complete. The overall result of this check is: Failed <<<<
Problem: The system does not have the required swap space.
Recommendation: Make more swap space available to perform the install.

What's the matter? Please help

Thank you very much

It's not the space under /tmp, it's the swap space to swap memory from ram to disk that's to small.

Is that an exact copy and paste of the session?

It seems wierd that oracle expects 48 gigabyte swap space, normaly swap space is configured to be about the same as the real ram. How much RAM has this box?

You could add an aditional swap file (Example for 1 gigabyte):

dd if=/dev/zero of=/tmp/swapfile bs=1k count=1024000
chmod 600 /tmp/swapfile
mkswap /tmp/swapfile
swapon -v /tmp/swapfile


But you should have a look with

swapon -s


What swap space is currently configured first.

Thanks,
As I wrote earlier my swap space size was 8385856 KB.
I added 16GB swap space, is it wrong to me?

A day ago while installing Oracle 10.2.0.1 on a server, I ran into the same problem, and so I decided to increase my swap space to the value that Oracle had recommended... But, just for the sake of experiment, I ignored the warning and proceed with the installation. It was expected to get errors of impossibility to copy a file or files into disk, but nothing extraordinary happened, I finished my installation successfully. Actually it doesn't mean that if you ignore this warning or other warnings you will end up finishing your installation successfully. Be careful and read documentation.

Check your current space; As per document add minimum space.

Thanks
