If the Multi-Channel Server (MCS) database password is modified or expired, you will need to update the appropriate MCS files.
The ImportPolicies script or batch file is used to import a portlet's policies when a portlet is installed. The ImportPolicies file is located in the wp_root/wp.mobile/wp.mobile.mcs/repository/bin/ directory when MCS is installed with WebSphere® Portal.
The mcs-config.xml file contains the MCS configuration parameters.
To update this file, change the password attribute value in the anonymous-data-source element.
