Just make sure that the real DASD one is used last by making sure the VDISK
ones are prioritied.
See the help file for v1310 of SWAPGEN... 8-)
If you haven't already done so, make sure the VDISK system and per-user limits
are set to Infinite in SYSTEM CONFIG and that you have enough VM page space to
back the demand.

First re
You are correct. For successful Oracle implementations it is necessary to
estimate the memory requirements, by considering SGA, PGA, number of
dedicated connections, Linux page table requirements, ASM, RAC etc., The
total of swap space and the guest memory relates to how much virtual memory
is ava
I would stick with the smaller swap ... as you say, if the server is
swapping a lot, it's better to give it more main memory and let z/VM manage
memory paging then let Linux continue swapping.
I always prefer to give less (memory and swap) initially and add more if
actual behavior warrants it. N
I have a request for a linux server that will be hosting an oracle data base.
The requestor has requested 8G of main memory and 8G of swap (Our normal server
usually has 1.5G of swap - .5 on dasd and 1G on vdisk).
Does anyone have any thoughts about giving this person 8G of swap ?

It all depends on what they are trying to door if they are blindly

they have 30 GB of disk space on a current server (and not telling you how much

For big Oracle shops, 30GB is less than rounding error.

Oracle software on our intel oracle 11G r2 RAC cluster is about 4.5G
each for Oracle DB and the Grid/Clusterware installs. Call it 10G all
together.
So another 20GB for some test databases doesn't sound completely out of
