David,
I  am on os390 2.10 running a 4.2 server and changed to mpthreading yes last
year.
Have had no issues.
To get most noticeable benefits you need to be in the scenario where :-

 You have a multi processor mainframe
Adsm is currently running its single processor at 100%
The mainframe overall is not running at 100%
John

Subject:  MPTHREADING



We are running OS390/2.10 with TSM 4.2.1.9 currently we have MPTHREADING
set to NO.
 I was considering changing it to yes. Has anyone had problems with the
MPTHREADING?
Also, what if any improvements can I expect?
