Data Replication on Oracle DB

Hey

[Quoted] [Quoted] If any one can help me on data replication on Oracle 8i DB. Precisley I want to do :

1. Replicate the data from one set of tables to another set of tables in a seperate DB instance. The replication should only work for inserts and updates. That is it should only replicate the data for inserts and updates.
2. I do not want to use triggers as I can have severe performance issues
3. I would welcome any ready made tool available to do this.
4. As this deals with a transaction system, and the database size is large, the replication method should have minimum issues related to record locking, performance etc.

Thanks

Anant
