Jack,  

I had thought of that but at this point I am not sure if that is in fact the issue. I am able to restore the control file and since I am using a controlfile rather than a catalog with my RMAN backups all the information is in the controlfile. I suspect the problem is due to the fact that I am trying to clone the primary of a DataGuard installation and that somehow I need to alter the controlfile and remove the DataGuard configuration information. I'm not sure that makes sense but that is what I am thinking at this point.

since this is UNIX can't you simply put in a link that mimics the original location of the backup pieces?

Greetings,

We are running Oracle 10.2.0.4.0 EE on RHEL4, 64-bit. I am using Data Guard and doing daily RMAN backups on the primary and am not using a catalog. I am attempting to duplicate the primary database to another server on which, because of disk layouts the RMAN backup pieces are in a different location than on the production server I am trying to duplicate.

I have found instructions on how to do this. On the second box I start up the database nomount, restore the control file from the backup pieces on the second box, mount the database and use the catalog command to indicate the new location of the RMAN backup pieces. That all works fine. Then I run my script to restore and recover the database and I get the following errors...

RMAN-03002: failure of configure command at 07/02/2008 17:03:44 RAMN-05021: this configuration cannot be changed for a BACKUP or STANDBY control file

I don't know if there are additional steps necessary to clone the primary database in a Data Guard configuration or if it is because I am not using a catalog. I do realize there are certain things one cannot do with a Data Guard configuration without a catalog and I don't know if this is one of them. If that is not the case can anyone help me with the additional steps I must take to get this to work. Here is the script I am invoking from RMAN...

run {
configure auxname for datafile 1 to
'/u01/oracle/edrstest/system01.dbf';

configure auxname for datafile 2 to
'/u01/oracle/edrstest/undotbs01.dbf';

.
.
.

configure auxname for datafile 11 to
'/u01/oracle/edrstest/mvlog01.dbf';

set newname for tempfile 1 to
'/u01/oracle/edrstest/temp01.dbf';

restore database;
switch datafile all;
recover database;
alter database open resetlogs;
}

Suggestions graciously accepted. Thanks.
