If you configure a WebSphere® Application Server data source for the MCS database, an informational message will be entered in the /logs/WebSphere_Portal/SystemOut.log file.
The following informational message will be contained in the wp_profile_root/logs/WebSphere_Portal/SystemOut.log file:
5/17/09 9:00:35:927 EDT] 759cef ConnectionFac I J2CA0122I: Resource reference jdbc/mcsDS could not be located, so default values of the following are used: [Resource-ref settings] res-auth: 1 (APPLICATION)
