Did you think to llok the message up in the manual?  It tells the whole 
story!  Anyway, here is the message from printed from BookManager/MVS.

(I have done the same type of testing with no problem.  Apparently you 
license ADSM in a different way than I do).

Hi,

This is a question for the MVS people out there.  We are putting up an 
OS/390 V 1.3 system for preliminary testing.  When I tried starting ADSM on 
that system I got the following msg:

ANR9954S  ADSM is not licensed for use on this system.

We are ADSM/MVS 2.1.03.  Level 1 ADSM and MVS support have not been able to 
help.  I am awaiting a call back from Level 2 ADSM.  Just thought someone 
out there might have a clue, in the meantime.

Thanks,
