Looks like I better stick to the configuration in doc#1436807.1, in which I'm at the Portal config part. Getting an error where I specify Portlet schema, RCU 11.1.6 didn't create any schema with name "portlet" in it and I'm getting an error when I create a PORTLET schema myself. Any ideas?
Obviously something is wrong here. When you select the <PREFIX>PORTAL schema, the <PREFIX>PORTLET schema below the WEBCENTER component is automatically selected. To avoid any issues, remove all schemas with mrca and recreate them. Be careful not to uncheck the <PREFIX>_PORTLET schema.
