okay - you could change the COMPRESSALWAYS to 'NO', the default is at 'YES'
Otherwise already compressed files normally grow with the tsm compression
and so 'COMPRESSALWAYS NO' can disable compression for those files.

Thanks . . .

Grrrrrrr . . . I figured out what is happening.  The files that are backed
up are unix compressed (foo.Z).  The dsm.sys file is set with "compression
yes".  Of course the cpu is spinning, it's uncompressing the file which is
already compressed!!!!

Hi,
you may try instead
dsmc restore "/oracle/backup/fedwp1/bkup.hpdw1p.200903081920.fedwp1.hot/?*"
/oracle/backup/paul/ -inactive -subdir=yes -replace=no

This would deactivate the nqr -feature and we use it often when restoreing
quite small
number of files out of bigger file-spaces.

regards
Rainer

We are performing a restore that is running real slow.

client:  hpux 11.11, tsm v5.5.0
tsm server:  v5.4.1

The restore operation is about 1000 files totaling about 600gb. The tsm
server is sitting with the session on SendW.    When dsmc is first

started

it runs the restore at about 10-15mb/s.  After some time (an hour or so)

it

slows to a crawl.  The problem appears to be that dsmc is running an

entire

processor flat out at 100%.  In other words, dsmc becomes cpu bound.  We
have killed and restarted it several times and the same pattern occurs.

Here is dsmc cmd we ran:
dsmc restore /oracle/backup/fedwp1/bkup.hpdw1p.200903081920.fedwp1.hot/
/oracle/backup/paul/ -inactive -subdir=yes -replace=no

Any thoughts on what's happening would be appreciated!

Rick
