I am using 8i (8.1.7) on windows 2k SP4 with no recovery catalog. I am
facing issues in recovery from control file backups. I am trying to do
redirected restore from Machine A to Machine B. On Machine B I have
prepared the instance with the same name and DB ID.

I have three backups and I can restore only through the first (oldest)
backup. Please see below the procedure I am following to restore:
(Followed the procedure listed in
http://download-west.oracle.com/docs/cd/A81042_01/DOC/server.816/a76990/rmanreco.htm
in section "To restore from HOST_A to HOST_B without a recovery
catalog:")

- Copy the control files to machine B

- Get the SCN by executing the query:
****
SQL> SELECT min(scn)
2 FROM (SELECT max(next_change#) scn
3 FROM v$archived_log
4 GROUP BY thread#);

MIN(SCN)
----------
362799
****

- Run following RMAN script
****
RUN {
ALLOCATE CHANNEL ch0 TYPE 'SBT_TAPE';

RESTORE DATABASE UNTIL SCN 362799;

RECOVER DATABASE UNTIL SCN 362799;

RELEASE CHANNEL ch0;
alter database open resetlogs;
}
****

This works correctly for the first backup. And I can get the instance
up and running. Please note the output of "list backup" at this point
of time below: Output shows the maximum SCN is 362797.
****
RMAN> list backup;

Now the problem is if I restore control files from the second or third
backup then for the above mentioned RMAN script I get following error:
****
RMAN-06003: ORACLE error from target database: RMAN-20208: UNTIL
CHANGE is before RESETLOGS change
****

Please note that query to get SCN still returns me 362799 so I had to
use 362799 in the RMAN script.
****
SQL> SELECT min(scn)
2 FROM (SELECT max(next_change#) scn
3 FROM v$archived_log
4 GROUP BY thread#);

MIN(SCN)

362799

Please note the output of the list backup command at this point:

RMAN was in its buggy infancy with 8.1.x; using it with that release
series is not advisable.
