Are More Actions Required for Downstream Capture without a Database Link?
When downstream capture is configured with a database link, the database link can be used to perform operations at the source database and obtain information from the source database automatically. When downstream capture is configured without a database link, these actions must be performed manually, and the information must be obtained manually. If you do not complete these actions manually, then errors result when you try to create the downstream capture process. Specifically, the following actions must be performed manually when you configure downstream capture without a database link: In certain situations, you must run the DBMS_CAPTURE_ADM.BUILD procedure at the source database to extract the data dictionary at the source database to the redo log before a capture process is created. You must prepare the source database objects for instantiation. You must obtain the first SCN for the downstream capture process and specify the first SCN using the first_scn parameter when you create
