Thanks for all the great info. and suggestions. I have another question regarding memory and vm. One of the sales reps was saying that memory on the z/Series under z/vm had a 10 to 1 ratio over memory on intel, meaning if we had a intel box using 10 gig of ram that we would only require 1 gig

Tobias, As Daniel has already told you, /etc/inittab controls this. I ship an inittab that has a bash shell running on the VM console. I would recommend that you look at bootshell in the /extra directory. This is a simple tool written by Mike Kershaw of Marist College that sits on the console

Hi Doug, you should consider using ficon attached storage on the z800 for database workload. In addition, consider using LVM striping over multiple volumes or alternatively LVM multipath on parallel access volumes to get your IO thoughput up to a reasonable level. With regard to memory size, you

First, any salesman with a rule of thumb like 10:1 scares the everything out of me Your 1GB of storage will at most support an 800MB virtual machine. YOU CAN NOT OVERCOMMIT STORAGE if you only run one virtual machine. You can ONLY make the virtual machine small enough so that it fits in the VM

I've seen that behavior on a system with a lot of open files (it keeps a context entry to go back and check later in the run to see if the file is closed and available), but that doesn't seem to be the case here. Is this the first backup of that filesystem on this server? Sometimes the first
