Re: Backup performance on mixed-mode server

In theory, if you have only one interactive job on system, server
scheduling algorithm will not kick in and you should have unconstrained
performance for your job (I guess it was done exactly for this case -
backup scenarios).

Subject:  Backup performance on mixed-mode server





We currently have a V3R2 CISC machine.  We do the backups from the
console interactively (not batch) since we bring the system to a
quasi-restricted state.  The only subsystems remaining active are QCTL
and QSPL.  QCTL has only the console and QSPL has only the printer
writers.

Later this year, we will be replacing the CISC with a 170 mixed-mode
server.  In a mixed-mode server, will we get better backup performance
if the actual save is submitted to batch; and the console simply waits
for a completion message?  I.E., will the "CFINT?" job(s) kick into gear
when doing an interactive backup, even if the other subsystems such as
QBATCH, QINTER, QSERVER, etc are down?

Thanks for any insight.
