Can you help me? I meet some errors when I do incomplete recovery with RMAN

Question

In recover step, There are following errors:
RMAN-11001: Oracle Error: ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/d/db/oradata/db01/system01.dbf'
question:
1. Should I restore archive log files generated on July 16th back to orignal archive directory in order to avoid to recover failure?
2. Or Should I add the command "sql 'alter system archive log current'" in the backup script in order to avoid to recover failure?
The following is the detail information:
The database is ok when I try to do incomplete recovery database that was fully backed up on July,16th,2004. The database is oracle 8.1.7 and is in the archive mode:
The following is the backup script:
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=db01,OB2BARLIST=ora8i_online)';
backup incremental level 0 filesperset 1
format 'ora8i_online<db01_%s:%t:%p>.dbf'
database
include current controlfile
archivelog all delete input;
I use it to do a full backup on July 16th,17th successfully.
And I use the following scripts to do incomplete recovery:
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=ORACLE8,OB2APPNAME=db01)';
sql "alter database mount";
set until time ='17.07.2004';
restore database;
recover database;
sql "alter database open resetlogs";
sql "alter database open";
There script is successful in restore step. But there are some errors in recover step. The detail information is showing in following log:

I repeat my questions:
1. Should I restore archive log files generated on July 16th back to original archive directory in order to avoid to recover failure?
2. Or Should I add the command "sql 'alter system archive log current'" in the backup script in order to avoid to recover failure?
Can you help me ? Thank you.

Answer 1

You are correct. In RMAN8i, you should add the "alter system archive log current; command before you backup the archive logs.
You are running into the case where Oracle needs additional redo to make the database consistent that was located in the current online log at the time of the backup.
If you set UNTIL TIME to an earlier time does the recover work?
In Oracle9i, if you issue the command, "backup database plus archive logs", RMAN will automatically archive the current online log before performing the archive log backups.
