Environment: Oracle 8.1.7.4 on Solaris 5.8

I am trying to create a copy of a database from an rman hot backup
running in nocatalog mode, following the example in the Duplcate command
section of the Oracle "Recovery Manager Users Guide and Reference".

Here is my script:

=================================================================
#!/bin/ksh
#
# Create a new database from an rman backup.
#
# Parameters:
#     old database sid
#     userid
#     password
#     new database sid
#
#
export ORACLE_SID=$4
export NLS_DATE_FORMAT='DD-MON-YYYY hh24:mi:ss'
export NLS_LANG='american_america.WE8MSWIN1252'
rman target $2/$3@(protected)
connect auxiliary sys/sys_$4
run{
set until time='10-MAY-2007 15:45:00';
allocate auxiliary channel ch1 type disk;
allocate auxiliary channel ch2 type disk;
allocate auxiliary channel ch3 type disk;
allocate auxiliary channel ch4 type disk;
allocate auxiliary channel ch5 type disk;
allocate auxiliary channel ch6 type disk;
set newname for datafile 1 to '/mnt1/oradata/psnew/system01.dbf';
set newname for datafile 2 to '/mnt2/oradata/psnew/tools01.dbf';
set newname for datafile 3 to '/mnt1/oradata/psnew/rbs01.dbf';
set newname for datafile 4 to '/mnt2/oradata/psnew/temp01.dbf';
set newname for datafile 5 to '/mnt3/oradata/psnew/users01.dbf';
set newname for datafile 6 to '/mnt3/oradata/psnew/indx01.dbf';
duplicate target database to psnew
    logfile '/mnt1/oradata/psnew/redo01.log' SIZE 500K,
  '/mnt2/oradata/psnew/redo02.log' SIZE 500K,
  '/mnt3/oradata/psnew/redo03.log' SIZE 500K;
}
exit
EOF

========================================================================
==

At the end of the script it give me the sequence of messages shown
below. My last archive log file was arch_1_181 so I would not expect
the script to find 182. I tried to connec from sqlplus as system and
got the message "initialization in progress" so I connected " / as
sysdba" and issued "alter database open resetlogs;".

Did I do this correctly?

Thanks,
Peter Schauss
