Question : Copy tables between databases

Hello all,
This is my first post on here so please forgive me if a make a mistake. My problem is that I have two Oracle 9i databaes for holding data associated with a steel mill. One of the databases is used at the production level (Level 2) and the other at the enterprise level (Level 3). I need to be able to copy tables from Level 2 to Level 3 automatically on a scheduled time basis and manually as and when required. All I have come up with so far is a stored procedure running on Level 2 which uses a database link to Level 3 to copy the records for the required tables. I'm not entirely happy with this solution and wondering is there a better way to do this? Thanks in advance

There are other solutions also like use COPY command to create or insert new rows from one database to another. You can use cronjob(unix) to schedule copying process automatically at OS level. You can use merge command etc. But the question is what makes you unhappy with your existing procedure?
