Oracle 11g: requirements: What is configured swap memory?

Hello Experts,

I just tried to install Oracle 11g on Linux (centOS). The documentation says that the minimum requirements is 1G of RAM; I have 2 GB. But, when I try to install, the kernel parameters fails because my net.core.rnem_default is less than the recommended value (4194304).

I am confused as to why the documentations says min of 1G of RAM; but in reality is 4G of swap memory? does this make any sense or am I misinterpreting?

if I change /etc/sysctl.conf
and set net.core.rnem_default to the recommended value, would the system crash because of lack of memory? but I do have enough recommended min memory...

thx so much in advance....

You can ignore that prereq to continue but you should be clear on RAM vs swap.

You can run Oracle with 2GB RAM and 2GB swap (if that is what you are asking).

Its a good idea to at least have 2x the amount of swap as RAM, if possible to change it.

To install while ignoring the prereq check use:

./runinstaller -ignoreSysPrereqs
