When the ADSM server starts it will start a lot of processes.  These
are ADSM threads.  The number of threads vary depending on the number
of data base and recovery log volumes since there will be one thread
for each of those volumes.  The are other threads for each of the
comm methods for accepting new conversations, migration and
reclamation watchdog threads that will start these processes when
needed, a deadlock detector, the server console, expiration watchdog
to start expiration at the appropriate interval, the schedule manager,
etc.  These threads do not stop and restart.

New threads (processes) are created and terminated as needed for
client sessions, tape mounts and dismounts, server processes, etc.

Hope this helps
