We have been running an automated weekly EXPORT SERVER on CMS for about a year.
The process runs CPU busy near 100% for 9 hours on a 16 mip processor to export
about 300k files totaling 4.2 GB of data.  I called IBM several times about the
performance problems early this year, but was told that is the way it is.  It su
   re
seems someone may be doing some sort of n**2 versus n log n algorithm.  I would
just like to lend my voice to any requirement that makes EXPORT SERVER more real
   ity
based in terms of ADSM backup/disaster recovery plans.

As for automation under CMS, I didn't spend much time, but things seems to work
pretty well.  A process kicks off at 0800 Saturday with a REXX line:

 call dsmcmd 'QUERY VOLUME FORMAT=STANDARD (VOLCMD.'

Dsmcmd is a stub of a REXX program that processes a command and returns output i
   n a
stem.  I use the command above to generate a tape pull list for the operators.

Next...

 call dsmcmd 'EXPORT SERVER FILEDATA=ALL DEVCLASS=3480 (EXPCMD.'

Next, wait 10 hours, then:

 call dsmcmd 'QUERY ACTLOG BEGINTIME=00:00 SEARCH=EXPORT* (LOG.'

Then Email the LOG. data to myself.

This process would not solve Melinda's problem--needing an interrupt at the end
   of
the EXPORT process.  I think that SCIF to PROP to trap message ANR0611I
(export server process ended) would be the easiest solution in this case.
