I have what appears to be an RMAN backup set, it has been multiplexed in 32 files, each containing 2-3 dbf's inside. The backupset refers to an SPFILE file, but it was not included in the set, the backup piece containing just that file was not included.
I have no catalog, no infrastructure, and no way to connect to original database. In addition the creators of the backupset have been evading my requests, I'm not sure why exactly but it appears to be business reasons. In other words this is what I have, I cannot get anything better than what I've got right now.
I have an Oracle enterprise server, with the data in a backup directory. What is the proper way to proceed? Is it possible to duplicate from an auxiliary backup data TO a fresh blank database? Meaning, is it possible to use an auxiliary as a primary?
