Use the Workflow Manager to create connections to databases. You can create connections using native database drivers or ODBC. If you use native drivers, specify the database user name, password, and native connection string for each connection. The PowerCenter Integration Service uses this information to connect to the database when it runs the session.
PowerCenter supports ODBC drivers, such as ISG Navigator, that do not need user names and passwords to connect. To avoid using empty strings or nulls, use the reserved words PmNullUser and PmNullPasswd for the user name and password when you configure a database connection. The PowerCenter Integration Service treats PmNullUser and PmNullPasswd as no user and no password.
