Prepare the Source Database to Send Redo to the Mining Database

To prepare the source database to send redo to the mining database:

Make sure that the source database is running with the required compatibility.
```
select name, value from v$parameter where name = 'compatible';

NAME            VALUE
---------       ---------------------
compatible      11.1.0.7.0
```
The minimum compatibility setting required from integrated capture is 11.1.0.0.0.

Set DG_CONFIG at the source database.

ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(dbms1,dbmscap)';

Set up redo transport at the source database.

ALTER SYSTEM
SET LOG_ARCHIVE_DEST_2='SERVICE=DBMSCAP.EXAMPLE.COM ASYNC OPTIONAL NOREGISTER 
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)DB_UNIQUE_NAME=dbmscap';

Enable the downstream destination.

ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;
