Recently I wanted to do RESET DATABASE. Oracle documentation suggests the following commands

connect target /

startup force nomount

reset database to incarnation 2

run {

set until time "date time"

restore controlfile from autobackup

alter database mount

restore database

recover database

}

alter database open resetlogs

In this view my db has given error: db not mounted. I haven't recovery catalog. So I changed: startup force mount.

Command reset database to incarnation 2 has given a result. But the command restore controlfile from autobackup

has given an error: need to use clause TO in mount or open mode. Then I put the command startup force nomount

before the command restore controlfile from autobackup. At this time rman has given an error: db not mounted.

I don't know in what work is. Please help me !
