Thanks all,

Problem is solved, I restored the database again ... now database server is
in online mode.... We have migrated so many times the system by restoring
the file system and database. only thing you have to care ie to keep the
data structure same on the secondary system.

Thanks

Rajesh Kokane

I disagree. We take out filestore backups using cpio (I have also done this
using tar in the past) and provided the restore on the DRS (or should it be
Business Continuity :-) ) machine is to the same path (fully defined and not
soft linked) then there will not be a problem, from an installation point of
view, with running the engine, there is no need to re-run the installation
scripts.

This looks more like a problem with the archive/restore sequence, I suggest
a Tech Support Call.

-> Hi,
->
-> hmm. Nice try - except that things don't really work that way ... :)
->
-> My guess is, that the problem of your procedure is "the file system
-> backup"
-> where you "attempt" to make a copy of the installation files
-> (i.e. the
-> product files) onto the other machine.
-> The copy on the second machine (your "DRS System") may be a valid
-> copy, but it's not a valid installation of the product.
->
-> You need to properly install the new version on your "DRS Ssystem",
-> for there's more to it than "just a couple of files in a few
-> directories"
-> ...
-> This installation needs to include the running of the
-> "installserver"-script
-> (or whatever it's called in 7.3x) as user "root" ...
->
-> Then you should take a proper backup from the production system
-> (using ontape or maybe doing an external backup) and restore
-> it on this
-> newly installed "DRS System".
->
-> From this point onwards you should be able to go with your normal
-> daily procedure ...
