    The performance of a WebSphere Process Server JAX-WS
    javax.xml.ws.Provider might degrade when invoked under
    high load.
    
    This occurs when the Service Component Architecture (SCA)
    component prepares the SOAP response. The problem is due to
    the way SCA invokes the JAX-WS runtime, resulting in a new
    namespace prefix created for each namespace URI, as shown in
    these debug messages:
    
    [1/24/11 12:11:16:625 PST] 0000007d OMSerializerU 1
    org.apache.axiom.om.impl.util.OMSerializerUtil getNextNSPrefix
    DEBUG_FRAME =
    org.apache.axiom.om.util.CommonUtils.callStackToString(CommonUti
    ls.java:80)
     DEBUG_FRAME =
    org.apache.axiom.om.impl.util.OMSerializerUtil.getNextNSPrefix(O
    MSerializerUtil.java:682)
     DEBUG_FRAME =
    org.apache.axiom.om.impl.llom.OMElementImpl.declareNamespace(OME
    lementImpl.java:372)
     DEBUG_FRAME =
    com.ibm.wsspi.sca.jaxws.data.JaxWsNativeDataHolder.constructBody
    FromBytes(JaxWsNativeDataHolder.java:251)
    ...
    
    [1/24/11 12:11:16:625 PST] 0000007e OMSerializerU 1
    org.apache.axiom.om.impl.util.OMSerializerUtil getNextNSPrefix
    Obtained next prefix:axis2ns2
    
    These messages would appear in trace enabled for
    org.apache.axiom.*=all
    

Problem conclusion

  • The JAX-WS runtime was changed to reuse existing prefixes
    previously created for the same namespace URI.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.19.  Please refer to the Recommended Updates
