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:

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