The MPTHREADING support on MVS can be used if you have Enterprise Management
    level code 3.1.2.0 applied.  APAR PQ19265 (spin loop) can occur under
certain conditions
    and will be fixed in the next PTF.  A fixtest for this problem is available
on index.storsys.ibm.com.
     We are still working through some of the performance issues with
MPTHREADING, however
      the option reportedly provides some relief to migration and heavy
BU/archive loads
      where several hundred simultaneous sessions are moving data to a single
server.
      Admin commands and central scheduling work can stack up behind client work
      during heavy client loading when MPTHREADING is not used.

Hi Christo,

we run our ADSM Server on a R54 and I am thinking about using
MPTHREADING Yes.
You say, ADSM used all your CPU.
Did you have WLM to keep ADSM on an reasonable level if cpu usage is to
high?

Normaly WLM does a good job in managing cpu-burners like ADSM or HSM.
