Enabling Swap

ajaye1971 · 04-19-2006, 02:00 PM

I have rehat 4.0E. whenever I boot the machine it takes a VERY long time at the ENABLING SWAP portion of the boot up. I do have a large swap do to ORACLE requirements. Is there anyway to speed this up?

Things you could try, not sure how great of an affect they'll make

mount your swap on a separate hard drive than other busy partitions
provide multiple swap partitions across several discs with the same mount/use priority
Use a raid solution to stripe some swap across a couple discs. This might not be wise if your Oracle information in the swap partition is critical

Mounting your swap on a different hard drive would probably speed up the boot process. This is actually a good process to do anyway, because having virtual memory on a drive that's constantly being used just slows everything down.

A RAID might be a good idea, but if that ORACLE information is critical, then redundancy is probably required. If you had enough disks, a RAID 0+1 would be handy. If not, maybe RAID 5.

Depending on how much memory you have in that system, you may not even need a large swap file.
