Oracle9i Database Replication

Hi,

I wish to implement the concept of database replication to create a standy database.

I want all dml's to be performed on the standby database for a given time frame, say 1 hour i.e., it will implement all dml's that is been executed in the live database in the standby database.

Can any body help me implementing the same.

Do a simple search on this forum and go through oracle documentation u will find plenty of them understand them and implement.After that if u got any errors post them here and expect an answer.
