Error Messages

QMAN-100001

  • Description: Incoming Qpid message contains a bad magic number.
  • Cause : The incoming message contains a wrong magic number (it differs from the expected value).
  • Action: QMan has nothing to do with this problem; Check on broker side in order to see if some protocol change occurred.

QMAN-100002

  • Message : Message I/O failure : unable to read byte message content and therefore it will be discarded.
  • Description: QMan is not able to read the incoming message stream.
  • Cause : Management messages have a predefined format and adhere to specific rules so cause for this problem can be a malformed message or a general I/O failure.
  • Action: See QMan logs for a better understanding of the exact cause and check if there are network issues and if something changed on broker side (especially protocol change due to an upgrade).

QMAN-100003

  • Message : Message processing failure : unknown exception; see logs for more details.

  • Description: A new event or object instance deletion has been notified; The corresponding JMX entity unregistration failed.
  • Cause : This is probably due to the fact that the requested instance no longer exists on QMan and therefore was previously unregistered.

QMAN-100019

  • Message : Unexpected exception occurred on WSDM adapter layer : probably request or response was malformed.
  • Description: Soap Request or response is malformed. Most probably issue occurs in the request (because response is automatically generated by QMan)
  • Cause : The WS-DM adapter deals with Soap messages, which must be valid XML documents. If one of them (request or response) is malformed you get this error.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see all XML messages that are exchanged during conversations.

QMAN-100020

  • Message : WS-Action not supported.
  • Description: An action request has been made to a QMan but the requested action is not supported by the target WS-Resource.
  • Cause : Each managed WS-Resource has capabilities that include several actions (it depends by the resource interface). Probably the request has been sent to the wrong resource.
  • Action: Using QMan administration console inspect the requested resource in order to see all the supported actions. Check the incoming request message in order to see if it is correct.

QMAN-100021

  • Message : Unable to build RDM for resource <resource_id>.
  • Description: Resource Metadata Descriptor is an artifact that is built when a WS-Resource is created. The RDM for the reported WS-Resource cannot be created.
  • Cause : RDM is basically a descriptor reporting the metadata for a WS-Resource so probably the problem is in the structure of the resource (properties, operations). It is also possible that a resource interface contains a datatype that is not supported.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts.

QMAN-100023

  • Message : Unable to build WS artifacts.
  • Description: When a WS-Resouce is created, its WSDL and RDM is generated too. The engine wasn't able to build those artifacts.
  • Cause : This is, as QMAN-100021, a problem with the interface / definition of the resource that needs to be created.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts.

QMAN-100024

  • Message : Unable to instantiate generated capability class for <resource_id>.
  • Description: When a WS-Resource is created, QMan is building several classes that represent its capabilities. This error indicates that at least one capability class failed to initialize.
  • Cause : This is, as QMAN-100021, a problem with the interface / definition of the resource that needs to be created.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts.

QMAN-100024

  • Message : Resource manager raised an exception while creating capability for <resource_id>.
  • Description: A resource manager is an internal component that handles resources lifecycle including creation and destruction. This error occurs when the resource cannot be created.
  • Cause : This is, as QMAN-100021, a problem with the interface / definition of the resource that needs to be created.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts.

QMAN-100024

  • Message : Exception occurred while replacing the placeholder soap address with resource actual location.
  • Description: Each WS-Resource has a WSDL that represents itself as a Web service. Service description is built starting from a template WSDL that contains a fake address replaced with the actual location when the resource is built.
  • Cause : This is an internal QMan error and should never appear because is due to a malformed WSDL template.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts.

QMAN-100027

  • Message : Shutdown failure while destroying resource <resource_id>.
  • Description: QMan was not able to destroy the resource <resource_id>.
  • Cause : Most probably the resource was busy when the shutdown has been requested.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log.

  • Cause : It is not possible to initialize a WS-Resource twice. Something was wrong on WS-DM Adapter.
  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts.

QMAN-100032

  • Message : Bad request has been received on this WS-Resource : Shutdown is not possible because the resource hasn't yet been initialized.

  • Action: Using QMan administration console enable a fine level for WS-DM adapter log. You should see detailed information about the lifecycle of each managed resources including generated artifacts. It is also possible that a wrong deletion message (content indication message) arrived from Qpid broker.
