How can I do a full recovery with 8i and norecovery catalog. It appears I need a recovery catalog to recover the control file. With 9i our control file is a seperate piece, we set the DBID, and then restore the control file. 8i documentation seems to indicate I need a recovery catalog....
Many thanks....

HI
It is just an advice!!!
You can backupup your current controlfile manual after you have backuped all datafiles(database),then the controlfile you backuped contains all backup records you need,you don't worry about that you can't use some backup because of the record in controlfile has been overwrited!!!
In the worst case,you lost some backup records,and you use RMAN with nocatalog,you can use package dbms_backup_restore to restore what you want,but it may be more difficult than normal!!!
the following script is for example:
--restore controlfile
DECLARE
devtype varchar2(256);
done boolean;
BEGIN
devtype := dbms_backup_restore.DeviceAllocate(type => '',ident => 'FUN');
dbms_backup_restore.RestoresetdataFile;
dbms_backup_restore.RestoreControlFileto('D:\ORACLE_BASE\controlfiles\CONTROL01.CTL');
dbms_backup_restore.RestoreBackupPiece('D:\ORACLE_BASE\Rman_Backup\MYDB_DF_BCK0BH1JBVA_1_1',done => done);
dbms_backup_restore.RestoresetdataFile;
dbms_backup_restore.RestoreControlFileto('D:\ORACLE_BASE\controlfiles\CONTROL02.CTL');
dbms_backup_restore.RestoreBackupPiece('D:\ORACLE_BASE\Rman_Backup\MYDB_DF_BCK0BH1JBVA_1_1',done => done);
dbms_backup_restore.RestoresetdataFile;
dbms_backup_restore.RestoreControlFileto('D:\ORACLE_BASE\controlfiles\CONTROL03.CTL');
dbms_backup_restore.RestoreBackupPiece('D:\ORACLE_BASE\Rman_Backup\MYDB_DF_BCK0BH1JBVA_1_1',done => done);
dbms_backup_restore.DeviceDeallocate;
END;
/
--restore datafile
DECLARE
devtype varchar2(256);
done boolean;
BEGIN
devtype := dbms_backup_restore.DeviceAllocate (type => '',ident => 'FUN');
dbms_backup_restore.RestoreSetDatafile;
dbms_backup_restore.RestoreDatafileTo(dfnumber => 1,toname => 'D:\ORACLE_BASE\datafiles\SYSTEM01.DBF');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 2,toname => 'D:\ORACLE_BASE\datafiles\UNDOTBS.DBF');
--dbms_backup_restore.RestoreDatafileTo(dfnumber => 3,toname => 'D:\ORACLE_BASE\datafiles\MYSPACE.DBF');
dbms_backup_restore.RestoreBackupPiece(done => done,handle => 'D:\ORACLE_BASE\RMAN_BACKUP\MYDB_DF_BCK05H2LLQP_1_1', params => null);
dbms_backup_restore.DeviceDeallocate;
END;
/
--restore archived redolog
DECLARE
devtype varchar2(256);
done boolean;
BEGIN
devtype := dbms_backup_restore.DeviceAllocate (type => '',ident => 'FUN');
dbms_backup_restore.RestoreSetArchivedLog(destination=>'D:\ORACLE_BASE\achive\');
dbms_backup_restore.RestoreArchivedLog(thread=>1,sequence=>1);
dbms_backup_restore.RestoreArchivedLog(thread=>1,sequence=>2);
dbms_backup_restore.RestoreArchivedLog(thread=>1,sequence=>3);
dbms_backup_restore.RestoreBackupPiece(done => done,handle => 'D:\ORACLE_BASE\RMAN_BACKUP\MYDB_LOG_BCK0DH1JGND_1_1', params => null);
dbms_backup_restore.DeviceDeallocate;
END;
