-->grep MemTotal /Proc/meminfo
-->free
-->df -m
--> grep SwapTotal /proc/meminfo
--> /usr/X11R6/bin/xdpyinfo

4. Redhat- Linux AS 3 patches:-

--> kernel 2.4.21-4-EL
--> kernel-smp-2.4.21-4-EL

--> ln -s /usr/bin/gcc296 /usr/bin/gcc
-->ln -s /usr/bin/g++296 /usr/bin/g++

7. After that you have to download the patch “3006854 “ form the site “oracle metalink “
