ORA-19906: 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 incarnation, change the recovery destination using RMAN's RESET DATABASE TO INCARNATION <incarnation#> command. To see which incarnations are available for this target database, query V$DATABASE_INCARNATION or use RMAN's LIST INCARNATION command
