Prod box us HPUX, Dev box is Linux RHEL 3. I am trying to use my backups to restore the production database over to the development box.

I am using rman (script in cron) to do my backups. Here is what the rman script looks like.

connect target

run {
allocate channel orabkup type disk format '/oracle10g/backups/%d/b_%u_%s_%p';
backup (database include current controlfile);
backup (archivelog all delete input);
}

report obsolete;
delete noprompt obsolete;

Here is RMAN configuration parameters on the Prod Box.

using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle10g/app/oracle/product/10.2.0/db_1/dbs/snapcf_instname.f'; # default

I moved over the 3 files created under the backup directory. Im assuming that one has the datafiles, one has the control files, and the other has the archive logs.

What would be the correct way to restore this database on the dev box using these 3 files? I have attempted to restore the control file but it complains every time about autobackup or that the piece is not a valid backup piece.

Thanks for the reply.

When trying to restore either the spfile or the control file I get the same error for both cases.

RMAN> restore controlfile from '/u01/b_4dip0b3o_141_1';

Iv tried that too, and it complains that it needs to be restored from autobackup?

RMAN> restore controlfile from tag 'TAG20070810T010004';

No...it was/is off

CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default


I see that many people say you should turn this on, but its off by default so I would assume that one would be able to do a backup and restore without having to change the default value?

I went ahead and tried what you said anyways and here is what I get...

RMAN> set dbid=4121490858;

executing command: SET DBID

RMAN> restore controlfile from autobackup;

So rman can not be used to restore a backup taken with rman unless autobackups is turned on?

If thats the case, why would it default to "off" if restores can not be done without it?

That's a good question. To keep the old behaviour, in time this does not exist, I think.

Nevertheless, you should be able to restore your controlfile from the backup as you included it.

I took a fresh backup with autobackups turned on. The only difference here was that it wrote my control file to the db_1/dbs path rather than to the directory where my datafiles and archive logs were backed up to.

I get the same exact error as above when attempted to restore my control file on the other box.

Could this be because box A is HPUX and box B is Linux?
Could this be because I don't have the same directory paths on box B?
Am I doing the correct steps to backup a database on box A and restore it on box B?

I dont think so.

Use ,
Restore controlfile from <specified path of path>
in nomount state

and in mount/open state use
Restore controlfile to < current control filename> from <backup filename of control file>

If you look at the third post, you will see that "restoring controlfile from path" was the first thing that was tried.

When you say "I don't think so", which question were you answering. I am leaning toward it being an issue between HPUX and LINUX. Everything I have tried seems to work just fine when using the same box to do the restore on, but keep in mind I am trying to restore the backed up files to a different box with a different OS.

Has anyone ever restored RMAN backups from a HPUX box onto a LINUX box?

You can not restore your database directly to RHEL from HPUX. However, since you are on 10g and want to copy the database to a platform with a different Endian format than your PROD box, you can consider Cross-Platform Tranportable Tablespace.

As a side note, even if you have CONTROLFILE AUTOBACKUP set to OFF, as long as you backup datafile #1 (which will be the case with a whole database backup), the controlfile will be backed up automatically. Nevertheless, it's good practice to set CONTROLFILE AUTOBACKUP to ON.

RMAN> configure controlfile autobackup off;

old RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP OFF;
new RMAN configuration parameters are successfully stored

RMAN> backup datafile 1;
