Dwight, we tested the aix-to-solaris-tsmdb-moving and it worked very fine-
so maybe we will use this as a regular 'quick-stand-by-server'
only for restore/retrieve purpose ( on data located on an
offsite-copy-server ) and *nothing else*
( no backup - no archive - no dbbackup ... ) and only just for
a short time in case of cpu-crash or in case of desaster.
It's not actual right now but my question is : if there is a need to change
the complete hardware (server platform , backup and archive libraries )
and assuming to have all data ( maybe temporarily for this action )
located on an offsite-copy-server ...
... can i thus move to the db on a new server-platform to get the access
to the db and to the offsite copy pools
then create new dev-classes pointing to the completely new
library-hardware - create a new primary STG on this newlib-devclasses
and the all by a command like
restore stgpool OLDSTG copypool=offsite-copy-pool newstgpool=NEWSTG
Is this a usual way to change to new server-platforms/librarys/tapes ... ?
it seems to be easy and straight forward -
Thanks in advance for any hints !

the test we have done:
the test we have done:
on production server-a ( aix-tsm 4.1.3.0 ) doing not all but some of the
full-DBB into a flatfile located on an solaris-system
on this solaris system server-b ( tsm4.1.3.0 ) with no tapes - only disk
and just the solaris server-package installed we load the db exported
by the production server-a
( this solaris system has some km distance to the production-server)
after shutting down the production-tsm-server on the aix system
-not to run both at once- we can start this solaris
'quick-stand-by-server' and have access
- to all the DB-entries
- to all data located on the offsite-copy-server ( server-c )
The dsmserv.opt on the solaris-server was started with
DISABLESCHED-set-to-YES to avoid any automatic processes
and
EXPINTERVAL-set-to-0 to avoid any db Expiration processes -
additionally we delete all admin schedules on the server-b after
starting.
All primary volumes were changed access to detryoed.
So the only thing would then be to change the clients field
'TCPServeraddress' to the Ip-Address of the solaris-server.
Any client with data that has a copy on the 'offsite-copy-server'
can then immediately restore/retrieve data ( to the time of the
last flatfile-fullbackup - which maybe not the most actual one ).
end of test
