Problem(Abstract) |
Errors can occur when the Embedded Messaging queues become
full in IBM® WebSphere® Application Server V5.0 and V5.1 releases. Use the
runmqsc tool to manage queues, change their properties, and clear messages
from a queue.
The following error message is a likely symptom of a full message queue:
WMSG0031E: Exception processing JMS Message for MDB ConnectorMDB,
JMSDestination jms/ConnectorQueue :
com.ibm.ejs.container.UnknownLocalException: ; nested exception is:
com.ibm.ws.exception.WsEJBException: nested exception is:
java.lang.OutOfMemoryError |

|
Cause |
Full embedded message queues can cause errors in WebSphere
Application Server.
Note: the instructions in this technote should only be used when
requested by IBM support.

Resolving the
problem |
- Change to the WebSphere MQ_home/bin directory.
- Run runmqsc.
- After the runmqsc shell runs, runmqsc requires that you specify the
queue manager name when runmqsc starts. Specify the embedded queue manager
name as WAS_nodename_servername, where nodename is
the WebSphere Application Server node name and servername is the
Application Server on which Embedded Messaging is running. Use
jmsserver as the servername when the node has been federated to a
cell.
- Type the command clear ql('WQ_MQQueueName') to clear the queue
MQQueueName from the runmqsc prompt,
- For WebSphere Application Server Embedded Messaging queue names, you
must prepend 'WQ_' to the queue name that is defined in WebSphere
Application Server; use the single quotes as shown below:
