The following example captures changes from database DBMS1 and DBMS2 by deploying an Extract at a downstream mining database DBMSCAP.

It assumes the following users:

• User GGADM1 in DBMS1 whose credentials Extract will use to fetch data and metadata from DBMS1. It is assumed that the DBMS_GOLDENGATE_AUTH.GRANT_ADMIN_PRIVILEGE() procedure was called to grant appropriate privileges to this user at DBMS1.

• User GGADM2 in DBMS2 whose credentials Extract will use to fetch data and metadata from DBMS2. It is assumed that the DBMS_GOLDENGATE_AUTH.GRANT_ADMIN_PRIVILEGE() procedure was called to grant appropriate privileges to this user at DBMS2.

• User GGADMCAP in DBMSCAP whose credentials Extract will use to retrieve logical change records from the logmining server at the downstream mining database. It is assumed that the DBMS_GOLDENGATE_AUTH.GRANT_ADMIN_PRIVILEGE() procedure was called to grant appropriate privileges to this user at the downstream mining database DBMSCAP.

This procedure also assumes that the downstream mining database is configured in archive log mode.
