Ontape recovery ?
Posted in 1998
Hopefully, I can present this in a cohereny manner.
This is the situation. We backup our 7.14 database using ontape. We
have a problem where some data got blown away several weeks ago, and
it was just now discovered. I have an ontape Level 0 from three weeks
ago. Obviously, I can't restore this tape to the current production
database.
What I would like to do is restore this tape on the same machine in a
different instance using the same chunk names but using symbolic links
to different raw devices. For example:
Current production database resides in the dbspace pdata.
pdata's pathname is /dev/informix/prod/pdata.
In turn, /dev/informix/prod/pdata is a symbolic link to
/dev/vg01/pdata.
For the restored database I have also create a chunk called pdata.
However, pdata's pathname in this instance is
/dev/informix/restore/rdata which in turn is a symbolic link to
/dev/vg02/rdata.
Will this restore procedure work, all other configuration parameters
being equal, without clobbering my production database?
In other words, does the ontape -r actually look to the pathnames to
the chunk, or does it only care that the chunk exists in the new
instance?
