Didn't I see in one of the red books where ADSM, when running with 1
     or 2 mirrors on the DB and having the DB in multiple small parts,
     allows ADSM to 1) write to the drive with the smallest latency time 2)
     allows each adsm task on the server to have open a specific DB
     file/portion so that enqueue problems are eliminated....

     Yo, IBM double check me on this....

     later

Can someone tell me in what case(s) the mirrored copy of the DB (and log)
is supposed to help.

I tried an experiment, since we're not yet in production.  I stopped
ADSM, then unmounted the file system on which one of the DB mirrors
resides.  Relaunching ADSM got it as far as the message

ANR7850I Process 39958 has terminated on signal 13 (Write Pipe, No Reader).

at which point it hung without starting any more than 2 dsmserv
processes.  It was impossible to connect an adminsitrative client and
therefore to do anything else.

Thanks in advance for any help or suggestions.  John
