You can either create database links manually, or use Oracle DBA Studio in the Oracle Enterprise Manager to perform this step. Oracle DBA Studio allows workflow administrators to quickly and easily create and administer database links, queue tables, queues, and queue propagation without requiring knowledge of the SQL DDL commands. See: DBA Management Pack, Oracle Enterprise Manager Administrator's Guide or the Oracle Enterprise Manager online help.

You can use the following syntax to create a database link manually:

CREATE DATABASE LINK <database link name> CONNECT TO 

	<user> IDENTIFIED BY <password> 

	USING '<connect string>';

For example:

CREATE DATABASE LINK wf817.us.oracle.com CONNECT TO 

	wfuser IDENTIFIED BY welcome 

	USING 'wf817';

If you have multiple installations of Oracle Workflow on both the local database and the remote database, and you want to use the same username and password to access both systems, you can omit the <user> IDENTIFIED BY <password> clause. In this case, the database link uses the username and password of the user who is connected to the database.

CREATE DATABASE LINK <database link name> CONNECT TO 

	USING '<connect string>';

If you want to create a public database link available to all users, specify the parameter PUBLIC.

CREATE PUBLIC DATABASE LINK <database link name> CONNECT TO 

	<user> IDENTIFIED BY <password> 

	USING '<connect string>';

To verify the names of your database links, use the following syntax:

SELECT db_link FROM all_db_links
