| Hi, I use Oracle 9i and would like to mix two different databases into one. These two databases have different tables and views. Each name of a table or view is unique and does not exist in the other database. Now I would like to bring them all together into a new database so that this new database has all the information of the other two databases (table-descriptions and contents of tables/views). Also it would be great if this would be possible autimatically at a special time, i.e. in the night. If you can help me and have a manual reference, please tell me the URL because I am really new to Oracle. Thank you very much, Dennis |

| How big the schmeas are in those database? I think export and import would be a good idea in this case. Take schema export from one database and import it in the a database where you want. For an example, On database A exp system/password@tnsname file=username.dmp log=username.log owner=user_name_which_you_want_to_export direct=y statistics=none On Database B Create a similar user and with the exact default tablespace (for convineance purpose). Once done with user creation. imp system/password@tnsname file=username.dmp log=imp_username.log fromuser=username touser=username statistics=none once you see 'imported successfully finished without warning', then analyze the newly imported schema in database B.
