["u9223508" <>]

Dear all :
When I using perfSONAR UI/interface to show my MA utilization , can’t shown 
any data from my MA , and when I using perfSONAR UI/playground ,
then input the follows query to request my geant2-java-rrd-ma 

<nmwg:message type="SetupDataRequest"
        id="mdrq1"
xmlns:netutil="http://ggf.org/ns/nmwg/characteristic/utilization/2.0/";
        xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";
        xmlns:nmwgt="http://ggf.org/ns/nmwg/topology/2.0/";>
  <nmwg:metadata id="meta1">
    <netutil:subject id="subj1">
      <nmwgt:interface>
      </nmwgt:interface>
    </netutil:subject>
<nmwg:eventType>http://ggf.org/ns/nmwg/characteristic/utilization/2.0</nmwg:eventType>
  </nmwg:metadata>
  <nmwg:data id="1" metadataIdRef="meta1"/>
</nmwg:message>

But response the error message as follows :

<?xml version="1.0" encoding="UTF-8"?>
<nmwg:message id="mdrq1_resp" messageIdRef="mdrq1"
  type="SetupDataResponse" xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";>
  <nmwg:metadata id="resultCodeMetadata">
    <nmwg:eventType>error.common.storage.xmldb</nmwg:eventType>
  </nmwg:metadata>
  <nmwg:data id="resultDescriptionData_for_resultCodeMetadata" 
metadataIdRef="resultCodeMetadata">
    <nmwgr:datum 
xmlns:nmwgr="http://ggf.org/ns/nmwg/result/2.0/";>MetadataConfigurationStorageManager.executeQuery:
 Connection to xml database failed</nmwgr:datum>
  </nmwg:data>
</nmwg:message>


But when I using echo request it’s response “success.echo”, Then self-test 
request is response as follows :

<?xml version="1.0" encoding="UTF-8"?>
<nmwg:message id="message1238071563_resp"
  messageIdRef="message1238071563" type="EchoResponse"

  <nmwg:metadata id="localhost.-2b9cd1f:11f88790d11:-62f6">
    
<nmwg:eventType>http://schemas.perfsonar.net/tools/admin/selftest/1.0</nmwg:eventType>
  </nmwg:metadata>
  <nmwg:data id="localhost.-2b9cd1f:11f88790d11:-62ef" 
metadataIdRef="localhost.-2b9cd1f:11f88790d11:-62f6">
    <nmwg:data id="resultDescriptionData_for_resultCodeMetadata" 
metadataIdRef="resultCodeMetadata">
      <nmwgr:datum 
xmlns:nmwgr="http://ggf.org/ns/nmwg/result/2.0/";>MetadataConfigurationStorageManager.executeQuery:
 Connection to xml database failed</nmwgr:datum>
    </nmwg:data>
    <nmwg:metadata id="resultCodeMetadata">
      
<nmwg:eventType>http://schemas.perfsonar.net/tools/admin/selftest/ma/geant2-java-rrd-ma-3.1/random-fetch-test/failure/1.0</nmwg:eventType>
    </nmwg:metadata>
  </nmwg:data>
</nmwg:message>

Any ideas on how to solve this?
