   Thanks for your quick reply. 
   
   What I want to do is to load an existing TDB2 database. 
   
   Here is the `assembler.ttl`:

   <#service_tdb_all> rdf:type fuseki:Service ;
       rdfs:label                         "TDB2 ds" ;

       fuseki:dataset                     <#tdb_dataset_readwrite> ;
       
       .
   
   <#tdb_dataset_readwrite> rdf:type      tdb2:DatasetTDB2 ;
       tdb2:location  "/wbfile/draft/locTest/expectedDbDir" ;
       ##tdb2:unionDefaultGraph true ;
       .
   ```
   
   Here is the test: 
   ```bash

             "value": "36"
           }
         }
       ]
     }
   }
   [17:00 1 wangbo@msg8:locTest] kill %1
   
   [17:00 1 wangbo@msg8:locTest] # Load the TDB2 database with assembler

   ```
   
   Is the `assembler.ttl` correct?
