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 on Oracle site 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.
****

2 FROM (SELECT max(next_change#) scn
3 FROM v$archived_log
4 GROUP BY thread#);

MIN(SCN)

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

Can anyone let me know what I need to do to restore and recover from
my second / third backups.

Thanks in advance,

This could be an old bug with 8i.
Try again without the RELEASE CHANNEL.
Quote:
RUN {
ALLOCATE CHANNEL ch0 TYPE 'SBT_TAPE';

RESTORE DATABASE UNTIL SCN 362799;

RECOVER DATABASE UNTIL SCN 362799;
RELEASE CHANNEL ch0;
alter database open resetlogs;
}


And please use CODE tags for readability.

Tried without release channel but it did not help. Pasting the RMAN output below:

RESTORE     DATABASE     UNTIL SCN 362799;  RECOVER      DATABASE      UNTIL

alter database open resetlogs;  }

reset database to incarnation to_previous_incarnation.


and then restore and recover.

Was the archive log mode changed on the primary database?
