RMAN Restore/Recover a database UNTIL TIME

RMAN Restore/Recover a database UNTIL TIME


Below are the steps for Restoring/ Recovering an Oracle database until a specific time in the past:


1) Set the environment:

on Windows:

set ORACLE_SID=DB10

echo %ORACLE_SID%


on AIX/Linux:

export $ORACLE_SID=DB10

echo $ORACLE_SID


2) Connect to rman:

rman target / nocatalog


3) Start the database in "mount" state:

startup mount;


4) Run the following :

Restore:

restore database UNTIL TIME "to_date('08/07/2020 06:15:00 pm','mm/dd/yyyy hh:mi:ss am')";


Recover:

recover database UNTIL TIME "to_date('08/07/2020 06:15:00 pm','mm/dd/yyyy hh:mi:ss am')";


alter database open resetlogs;


OR


run

{

set UNTIL TIME "to_date('08/07/2020 06:15:00 pm','mm/dd/yyyy hh:mi:ss am')";

restore database;

recover database;

alter database open resetlogs;

}


Note: 

We cannot restore/recover the database in "open" state, below error you faced while doing it.
