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

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

You can also use the Check Setup web page to verify that your database links are set up. See: Checking the Business Event System Setup.
