Re: Sharing info Oracle8i on Solaris x86

Having administered some systems with Oracle installed, I know from experience that Oracle requires 2 to 3 times RAM for swap space. Common sense says that on large systems with multiple gigabytes of RAM this is not necessary, but on smaller systems, use this as the rule of thumb.

Hope this helps.
