Ok. This is what my present plan is. I am FTPing the 2/26/10 backups from test server to production server so they will reside in both places. Then I will catalog the production server with the start with clause. Then I will re-attempt the duplication using the until clause. The ftp will take a few hours. I'll let you know if this was the issue. I appreciate all the input.

All backups and archived redo logs used for creating and recovering the duplicate database, however, must be accessible by the server session on the duplicate host. If the duplicate host is not the same as the target host, then you must make backups on disk on the target host available to the duplicate host with the same full path name as in the primary database. When using disk backups, you can accomplish this goal in any of the following ways: *Manually transfer the backups from the primary host to the remote host to an identical path. For example, if the backups are in /dsk1/bkp on the target host, then transfer them to /dsk1/bkp on the duplicate host. *Manually transfer the backups from the primary host to the duplicate host at a new location. For example, if the backups are in /dsk1/bkp on the target host, then you might transfer them to /dsk2/dup on the duplicate host. The new path-in this example, /dsk2/dup-must be accessible from both the target and duplicate hosts. Run the CATALOG command to add these copies to the RMAN repository at the duplicate host. *Use NFS or shared disks and make sure that the same path is accessible in the remote host. For example, the NFS mount point for both hosts could be /home/file_server." Privileged/Confidential Information may be contained in this message or attachments hereto.
