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 ?
I've been
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.
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

Thanks for all your answers. I guess I'll give him another vdisk of 4G and if
he
needs more, I can swapgen another vdisk.
Yeah, small incremental increases usually are good thing.
Is one 8G swap device better than 4 2G swap devices ? It's a lot easier adding
another swap device than

One more thing: check to see if your VM LPAR has some XSTOR defined. VM paging
implements a main store- XSTOR- real disk data migration path that helps a
lot with high paging levels and VDISK.
Your VM performance monitor will tell you lots of interesting stuff wrt paging
performance.
Only for z/VM 6.2 and previous..with 6.3, XSTOR is no longer
recommended, and in fact will be the last release to support it.

My suggestion would be if you are considering 4 GB of swap space, follow a
layered approach. Define two virtual disks, one for 256 MB and the next one
to be for 512 MB and a third lower priority swap disk (physical disk) for
the remaining required size. 4GB of swap as virtual disk alone is

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.
I tried using swapgen to define a 2G (4194304 blks) space and it says
Thanks - I ended up having 4 swap disks (1 500M dasd, one 1G vdisk and 2 2G
vdisks - total of 5.5G). I just hope that it's enough. Time will tell.
Just make sure that the real DASD one is used last by making sure the VDISK
ones are prioritied.
that uses file system storage

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

It all depends on what they are trying to door if they are blindly
following recommendations for the PC world. Or, for that matter, they know
they have 30 GB of disk space on a current server (and not telling you how much
is used).

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
