I can't give any technical references, but i can say what i did. When the installer complained about wanting 18gb of swap for our HP-UX Itanium Oracel 11.1.0.6 install, i tried to bypass it with only 4gb. It worked fine. The SA said he couldn't get to expanding it right away, and i got impatient. Just my experience. -----Original Message----- From: Bill Zakrzewski <bill@xxxxxxxxxxxx> To: Oracle-L@xxxxxxxxxxxxx <oracle-l@xxxxxxxxxxxxx> Sent: Thu, Mar 25, 2010 1:25 pm Subject: Swap Space I am installing Oracle 10.2.0.4.0 on a linux server running RH 5.x with 18gb of emory. According to the Oracle install guide it recommends a swap space equal o total memory or 18gb. Does it really require swap space of 18gb? If I llocate less space for swap (say 8gb), will that have any adverse effects? Thanks in advance, ill-- ttp://www.freelists.org/webpage/oracle-l
