There is a difference between the installation requirements and the runtime, as is usual. Installation requires x , but runtime doesn't - and the docs state 4GB as that's the amount needed to get a full install. If you're a min install, you might get away with 2GB without swapping to hard, but there we go. Once you've done the install, of course X isn't needed, but that will be for patching perhaps :-)
Once you're into runtime, then YYMV - it's your workload that generates the resource usage.

Our Oracle "specialist" ran a script from Oracle to determine requirements and demanded that the requirements would be met otherwise he couldn't install Oracle. This is an SLES11 with Oracle 11. So now we have a guest with 4G memory, 2G /tmp and a lot of packages installed, including a full X-windows. Installing Oracle we had proved through measuring the system that he needed only 200M /tmp space and less than 1G memory. X is never being used. So even the Oracle scripts and books do not reflect the actual minimal requirements but still consider a stand-alone server running X. BTW, the server is now installed according to Oracle recommendations, running at over 55MIPS it is now a top5 machine in CPU consumption and 100% in Q3. No, the machine is not in use yet so this is the IDLE load. Our SLES10 with Oracle 10 is a guest with a minimal installation, meaning the absolute minimum required to run a Linux guest and added a few packages such as sudo, sysstat etc. On top of that we've added: "cpp, gcc ,gcc-c++ , glibc-devel ,libaio-devel ,libmudflap, libstdc++-devel, java-1_5_0-ibm-devel, expat-32bit, fontconfig-32bit ,freetype2-32bit, glibc-devel-32bit, openmotif, xorg-x11-libs-32bit, zlib-32bit". So this is the actual minimum requirement. Anything more is not required to install or run an Oracle. Also the guest runs 2 oracle databases within 1G. Idle load at about 6MIPS and almost never in Q3. Conclusion, don't trust the requirements from Oracle, they are wrong. On the other hand, if you want to install using X then you indeed need a lot more than this.
