oracle.security.am.admin.config.ConfigurationException: Cannot find file oam-config.xml in the classpath or on the filesystem.

After installing oam, when using separate directories for the AdminServer domain and managed server domains, the following error will appear in the oam server logs:

oracle.security.am.admin.config.ConfigurationException: Cannot find file oam-config.xml in the classpath or on the filesystem.

Running the pack and unpack command to move configuration files to the managed server directory will resolve this error (after restarting the managed server).
