Hello

I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03

Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively

Now I have copied the backups from source db server to target and since path is changed, I cataloged it

However during restore I am getting

Quote:

ORA-19870: error reading backup

Here are the session details

RMAN> catalog start with '/u03/oradata/db7fra';

searching for all files that match the pattern /u03/oradata/db7fra

Hello

BTW I must mentioned that for the changed path of datafiles I intentionally not used db_file_name_convert etc. Just for experiment!

And anyways problem seems related to backups. Right?

How exactly did you restore the control file?

Hello Mahesh

Thanks for the reply

Since I cataloged all the backup and archivelog files with

catalog start with '/u03/oradata/db7fra';

and I copied the controlfile to '/u03/oradata/db7fra/DB7/autobackup/2011_03_15/o1_mf_s_745851045_6qyr55y3_.bkp'

I issued the command

restore controlfile from autobackup;

But now after your reply I fear that it might have restored the wrong one

RMAN> list backup of controlfile;

Now 2 things here

1) I don't know what is the controlfile backup at /u03/oradata/db7fra/DB7/backupset/2011_03_15/
it was at similar location on source db server (only /u04 instead of /u03)

2) since i executed the restore directly on console, not via stored script and unable to see it on the session I don't know which backup of controlfile is really restored. I assume 'from autobackup' would have restored that at /u03/oradata/db7fra/DB7/autobackup/2011_03_15

Your set newname command is asking to use /u03.
But RMAN is whining it cannot write to /u04.
Probably you are not telling us the whole story Smile

In case you think the recovery has taken wrong controlfile please let me know and I shall repeat all the exercise since start

Apart from this I could understand why there are 2 backups of controlfile?

Typo in your set commands.
Second one should be datafile 4?

Superb! Many Thanks Mahesh

Thanks for your time and patience to correct my mistake

After I corrected the error pointed by you (the file number), it went fine. Only here I did not try explicit incomplete recovery and RMAN did the correct thing

RMAN> run{
2> set newname for datafile 1 to '/u03/oradata/db7/system01.dbf';

One more update

During restore I mentioned

run{
set newname for datafile 1 to '/u03/oradata/db7/system01.dbf';
......
..
set newname for tempfile 1 to '/u03/oradata/db7/temp.dbf';

However after opening the database with resetlogs, I found

SQL> select file_name from dba_temp_files;
select file_name from dba_temp_files
                      *
ERROR at line 1:
ORA-01157: cannot identify/lock data file 101 - see DBWR trace file
ORA-01110: data file 101: '/u04/oradata/db7/temp.dbf'

Can we say the "set newname" does not take effect for tempfile?

OraKaran

Temp files are never backed up and/or restored by RMAN.
