See how much memory is actually being consumed by "ps aux" look for the %mem. (see the 4th column) Check system memory and swap "free -m"
Try to allocate just enough memory needed then use VDISK swap space with a
small contingency of real disk swap.

We are in the process of bringing up a Tivoli Storage Manager [TSM] server
using zLinux [SLES11] under zVM [6.2]. We are going to use the IBM7650G
with XIV back end storage to provide Virtual Tape. The idea is to backup
intel servers directly to tape then replicate to remote DR site.
We have run into problems with memory allocations. We were using 2GB
memory with 750MB of swap space in vdev. We started getting sql errors
with the indication that it was a memory or swap space issue. I have
increased the memory to 3GB and now the image will only allow us to run 11
TSM processes before getting errors. This will not be good for production.
I will increase this to 4 GB memory with 2GB of swap space to see what
happens.
Does anyone have experience and/or recommendations as to the correct
settings for memory allocations?
