yep, and I can also probably boot from a liveCD and repartition my drive to give the swap partition greater space too. I've heard (but have not confirmed) that my version of Linux can't access swap bigger than 2gig.
the reason I ask is that for my small loads (this is a box for study on) I wonder what the reason is for the needs of such amounts of swapspace?
I've installed and have it running at the moment and I just never see anything using my swap area at all. Given the load on the system (almost none) that isn't a surprise. If this were a commercial box with real commercial pressures I would be wondering if it might benefit from more.
I don't like the 'enigma' of black box stuff which many proprietary systems seem to be, and Oracle seems to be rather closed when it comes to internal operations (justifiably). Accordingly I thought I'd ask if anyone's done it (apart from me) and what their results (or errors) may have been.
