Hi,
I have been recommended a compress of the database ie. unload/reload as a cure
for
slow restores with large Novell data servers.
Has anybody been through this,  and can confirm my estimate of 6 hours approx
for the unload reload part of thr process.
We are OS390, TSM 3.7.20.0
The database is 84.5% occupied of 18.1gb   8 logical volumes ie :
Total Usable Pages: 4,764,672      Used Pages: 4,027,026
 Also any feelings on whether this is likely to make a real impact on the
database access
element of the restores.
Thanks, John

Has anybody been there, done it, got the figures.
I am looking for a nice warm feeling. I cannot have TSM unavailable for more
than 12 hours
max.
Thanks
