RMAN “set until time” example

So here is another post I will keep just for my own reference.

Whenever I need to perform an incomplete recovery of the database, I usually use the SET UNTIL TIME to specify the time for an incomplete recovery. Sadly, when NLS_LANG is not set properly, the time format that needs to be used is not something I can remember.

So here is an example for using SET UNTIL TIME with a sane time format:

run {
set until time "to_date('22-APR-2015 13:30:00','DD-MON-YYYY HH24:MI:SS')";
restore database;
recover database;
alter database open resetlogs;

You can find more examples in the Oracle documentation.

Mike Dietrich from the Oracle Upgrade blog has written an excellent article concerning this issue. Most specifically, MOS Note 1927265.1 notes implicitly that Enterprise Edition is a requirement:
