step 1. Make a full backup in Rman.
step 2. Make a new tablespace.
step 3. alter system archive log current

Now, I deleted all the controlfiles,dataflies,redologs, executed "restore controlfile" "restore database".
But ,when I executed "recover database",I see the follow errors:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of alter db command at 01/29/2007 17:44:57
ORA-01245: offline file 5 will be lost if RESETLOGS is done
ORA-01111: name for data file 5 is unknown - rename to correct file
ORA-01110: data file 5: '/opt/oracle/product/10.2.0/db_1/dbs/UNNAMED00005'

In the above case ,how can I rebuild the database using backup and archive log.

Please ,Thanks!

YOu have to restore the database prior to STEP1.
By default recover will try to restore and recover everything upto the point of failure. If your archivelogs are missing, you cannot do it.
Search this forum/documenation for TSPITR(tablespace point in time recovery)

As Mahesh indicated, RMAN will try to recover everything up to the point of failure, therefore you will need the archivelogs for this process to succeed.

After you MOUNT the database during the RMAN recovery, you could add the datafile(s) associated with the "new" tablespace with:

RMAN> sql "alter database create datafile ''<direcotry_path/file_name>''";

At this point, you can restore all the other datafiles that existed when the backup was taken:

RMAN> restore datafile 1, 2, 3, ..., n;

Then you can perform recovery and open with resetlogs:

RMAN> recover database;
RMAN> alter database open resetlogs;

Are you using TWO single-quotes (in red below) around the datafile name?

RMAN> sql "alter database create datafile ''<direcotry_path/file_name>'' ";

The quotes in blue are double-quotes.

The commands worked for me on 9i. I don't have the output from my session, but I can provide that once I have access to my system.

Check Recovering a Lost Datafile Without a Backup for additional details.
