CentOS - Apr 2007 - How to Increase Swap Memory in Centos 4.4?

To install Oracle Database 10g, I need to increase the swap memory to 1004
MB.
[root at server OpenBravo]# rpm -ivh oracle-xe-univ-10.2.0.1-1.0.i386.rpm
Preparing...                ###########################################
[100%]
This system does not meet the minimum requirements for swap space.  Based on
the amount of physical memory available on the system, Oracle Database 10g
Express Edition requires 1004 MB of swap space. This system has 504 MB
of swap space.  Configure more swap space on the system and retry the
installation.
error: %pre(oracle-xe-univ-10.2.0.1-1.0.i386) scriptlet failed, exit status
1
error:   install: %pre scriptlet failed (2), skipping
oracle-xe-univ-10.2.0.1-1.0

Below is my system information.
[root at server ~]# cat /proc/meminfo | grep MemTotal
MemTotal:       514152 kB
[root at server ~]# cat /proc/meminfo | grep SwapTotal
SwapTotal:      524280 kB
[root at server ~]# ipcs -lm

------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 32768
max total shared memory (kbytes) = 8388608
min seg size (bytes) = 1


Couldsomebody explain how to do this the fastest way? Thanks!

Do you have any disk space to add swap?

Tangential aside:  Does anyone have an informed opinion on whether the
"swap should be double RAM" rule still makes sense?

Assuming you've got the free disk space:

# dd if=/dev/zero of=swapfile bs=1024 count=512K
# mkswap swapfile
# swapon swapfile

(replace "swapfile" above with an appropriate path for your system).

Eventually you should make a permanent swap out of a real disk
partition, perhaps by adding a drive to the machine.
