Hi !!
I need to create a test database from production when it is running. Is this possible?
I am using rman to create my backups in production and here is the script ...
run {
backup
incremental level = 0 cumulative
filesperset 4
database plus archivelog
format '/u01/backups/vsid/hot/db_%d_%s_%p_%t'
tag = 'WHOLE_INC0';
delete noprompt obsolete;
}
exit
-------------------
I have 20 datafiles in my db and when I run the above script to create a full online backup, only one backup file is created in '/u01/backups/vdev/hot/' and 5 more files in '/u01/app/oracle/product/9.2.0/dbs/' Why? do I need this files to clone/duplicate my DB in another server?
I have this article which explain some steps but I am missing the restore piece and if I am not sure if I need to move the others 5 files in the dbs folder.
http://oracle.ittoolbox.com/documents/popular-q-and-a/how-to-clone-an-oracle-database-1623
if someone one please help me and send me a link, article, document with some help about how to clone/duplicate a database from rman?
thank you very much,
Gabriela

Becuase you are doing an incremental backup.
Do a full backup.
>>I have this article .....
The said article has nothing to do with RMAN duplication.
>>if someone one please help me and send me a link, article, document with some help about how to clone/duplicate a database from rman?
The documentation is the best resource.
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmdupdb.htm#441628
For more specific questions,
First search documentation,
then this forum and google.
