SOA 11g: "oracle.mds.config.MDSConfigurationException: MDS-01331: unable to load MDS configuration document" Unable to Deploy Human Workflow EAR File (Doc ID 1522354.1)

Last updated on AUGUST 27, 2019

Applies to:

Oracle SOA Suite - Version and later
Information in this document applies to any platform.


On : version, Workflow Service Engine

while deploying a Human Workflow application ear file, the deployment fails with the following error: 

oracle.mds.config.MDSConfigurationException: MDS-01331: unable to load MDS configuration document "file:/D:/Oracle/Middleware/user_projects/domains/phatest_domain/servers/soa_server1/tmp/_WL_user/SolutionAcceleratorInvoiceProcessing/7km41z/adf/META-INF/adf-config.xml"

Truncated. see log file for complete stacktrace


adf-config.xml was modified with the below configuration to add additional namespace required for the project:

         <namespace metadata-store-usage="mstore-usage_1" path="/soa/shared"/>
         <namespace metadata-store-usage="mstore-usage_1" path="/apps"/>
         <metadata-store-usage id="mstore-usage_1">
           <metadata-store class-name="oracle.mds.persistence.stores.file.FileMetadataStore">
             <property value="${oracle.home}/integration"
             <property value="seed" name="partition-name"/>



The issue can be reproduced at will with the following steps:
1. Create a human workflow app

2. Edit the adf-config.xml as mentioned above and compile that as an EAR
3. Deploy the ear onto SOA Server.
