I’m having big trouble in copying an Oracle DB to the same server but with another name, to use as a development DB.

I’m used to SQL Server, I’m new to Oracle (11g).

I wanted to use the ‘Database copy’ from SQL Developer, but I’m getting errors all the way. First it was about missing tablespaces.
Then when I manually created them in my new empty DB the errors were about missing users.
I wanted to create the users manually, but then I first needed to create missing roles.
When all that was done, it failed on missing indexes…

How do I copy everything I need with ‘Database copy’?

Any advice is greatly appreciated!

    SQL Developer copy will only copy objects between schemas. Do you want to just make a copy of a schema? Or a whole new database, including all schemas?

    Judging by your question, I’m assuming the latter. If so, RMAN “database duplication” may help you.

    See http://www.oracle-base.com/articles/11g/duplicate-database-using-rman-11gr2.php at Tim Hall’s excellent site.
