"recovery target incarnation changed during recovery"
*Cause: While a media recovery was active, a new incarnation was detected
by the server due to inspection or cataloging of archived logs
or backup files.
*Action: If you want recovery to use the new incarnation, restart recovery.
This is the most common action on a standby database when RESETLOGS
is done in primary. If you do not want recovery to use the new
change the recovery destination using RMAN's RESET DATABASE
TO INCARNATION command.
To see which incarnations are available for this target database,
query V$DATABASE_INCARNATION or use RMAN's LIST INCARNATION
