Information in this document applies to any platform.
When attempting to creating separate directories for the AdminServer and the Managed Servers (aserver and mserver),
this causes a custom portal application to fail with either a blank page or Internal Server Error if another managed server is started in the mserver domain directory.
Blank Page or Error 500--Internal Server Error
The WC_CustomPortal-diagnostic.log shows:
[2018-05-23T23:23:40.081+00:00] [WC_CustomPortal] [NOTIFICATION][J2EE JSP-00008] [oracle.j2ee.jsp][tid: [ACTIVE].ExecuteThread: '0' for queue:

unable to dispatch JSP page: The following exception occurred:.[[

MDS-00201: PDocument not found in MetadataStore : [store-type=DefaultMetadataStore app-name=SiteBPIMobile lookup-order=ServletContext,Classpath]
The issue can be reproduced at will with the following steps:
- Create a domain with a WC_CustomPortal and WC_CustomServicesProducer Managed servers.
- Create a separate directory for the Managed Servers per the following documentation:
Oracle Fusion Middleware Enterprise Deployment Guide for Oracle WebCenter Portal
8 Creating a Domain for an Enterprise Deployment
8.4 Post-Configuration and Verification Tasks
8.4.6 Creating a Separate Domain Directory for Managed Servers in the Same Node as the Administration Server
- Start the AdminServer (in the admin server directory).
- Start the WC_CustomPortal managed server (in the managed server directory).
- Deploy a custom Portal application to the WC_CustomPortal managed server.
- Access the application and confirm is works fine.
- Start the WC_CustomServicesProducer managed server (in the managed server directory).
- Access the custom Portal application.
