February last year within a 'Try&Buy' agreement with IBM we got our z890
upgraded
to a 2086-470 to test DB2 under zLinux. In this timeframe I left our PROD LPAR
with 2 dedicated
CPs for three months (the other two CPs were dedicated to zLinux). So for three
months we had
de-facto a 2086-270 and everybody was enthusiastic about that. Due to this
previous, successful
experience, we asked IBM how much this upgrade (from 230 to 270) would cost .

The batch window is shrinking. What I don't know is if our jobs have a single
TCB architecture
or can exploit more CPs in parallel .

I don't know. I need to investigate this together with SAG.
Thanks.
