We've found that when we use RMAN to recover an exact clone of a database
with the same name as the original to an alternate host (perhaps as test
database or fallback database while upgrading) we have to reset the
database in the RMAN catalog if both databases are in the same RMAN
catalog.
This has happened to us every time we recover to an alternate host using
the same database name.
We have gotten around this problem by export the RMAN catalog contents for
the original database and importing it into a different catalog. Then we
don't
have the incarnation problem.

Please respond
to ORACLE-L
Fawzia - Why do you think you need to perform a "reset database"? Have you
performed an incomplete recovery on the database (opened it with RESETLOGS
option)? If so, you have created a new incarnation of your database.
Therefore, none of your backups are valid because they occurred prior to
RESETLOGS. That is the reason for the "reset database" command. Obviously
what you should do as soon as possible after RESETLOGS is perform a full
backup. This backup will be valid (assume it is performed correctly).

Hi,
Please can someone explain the consequences of "reset database" in rman??
Does this mean all the previous backups are lost??Is there a way around ??
Any help/advice would be greatly appreciated...
