Hello all,

Please help because I did something stupid and I do not know how to correcti.

I copied (using cp command) some .dbf file under /u01/ofa to another directory (/u04/backup_dbf) and then delete the .dbf files from /u01/ofa.

These are the files I copied:
PP_STAS1.dbf
TEMP01.dbf
indx01.dbf
rbs01.dbf
system01.dbf
temp01.dbf
tools01.dbf
users01.dbf

Now I need to restore these .dbf files because I receive an error of "system01.dbf missing".

Also when I try to restore the specific datafile (RMAN> restore datafile '/u04/backup_dbf/system01.dbf' Wink

or all of them I receive the following error:

RMAN-03002: failure of restore command at 09/16/2008 10:38:34
RMAN-12001: could not open channel ORA_DISK_1
RMAN-10008: could not create channel context
RMAN-10003: unable to connect to target database using connect string "sys/manager"
ORA-01031: insufficient privileges

How can I restore these files?

Thanks in advance
Mimas

Which type of backup?
when you copied datafile then database is open/close which stage?

Now I need to restore these .dbf files because I receive an error of "system01.dbf missing".

where is the exact error message?

RMAN-03002: failure of restore command at 09/16/2008 10:38:34
RMAN-12001: could not open channel ORA_DISK_1
RMAN-10008: could not create channel context
RMAN-10003: unable to connect to target database using connect string "sys/manager"
ORA-01031: insufficient privileges
connect as sysdba privileged user.

Which type of backup?
What do you mean? I took before some days a backup using RMAN (database backup;) if that's what you mean.
when you copied datafile then database is open/close which stage?
It was open.

Now I need to restore these .dbf files because I receive an error of "system01.dbf missing".

where is the exact error message?
This error was received when I try to give an Insert command via sql. The error was saying that system01.dbf was missing from u01/ofa.
This is the path were this system01.dbf together with more .dbf files were existed before I copy and remove them.

I recommend you to read: Database Backup and Recovery Basics

You can't cp when the database is open (unless you put the tablespace in backup mode)
You can't restore with rman something you don't back up with rman (actually this is not completly true but at your level it is).

First read the book and stop trying to back up and restore or you will lose your database.
