WebLogic MBean help

Question

Hi
I want to know what is the value or how to get the value for “cursorHandle” parameter in the weblogic.management.runtime.JMSDestinationRuntimeMBean.getCursorSize() and
value for “selector” parameter in weblogic.management.runtime.JMSDestinationRuntimeMBean. deleteMessages().
The document is just telling “cursorHandle is an object of type java.lang.String that specifies: The cursor handle”
and
“selector is an object of type java.lang.String that specifies: A JMS message selector to identify which messages to delete”
This is in WebLoigc 10.
Thanks

Hi,
The cursor handle is the returned value of one of the getMessages() API and the selector is the standard JMS selector expression.
Here is the sample snippet showing how to get the cursor handle, size and use of selector.
For more information on the MBean, please see http://download.oracle.com/docs/cd/E12840_01/wls/docs103/wlsmbeanref/mbeans/JMSMessageManagementRuntimeMBean.html
WLST snippet:
=========
# connect to the server
connect(‘weblogic’,’weblogic’,’t3://localhost:7001’)
# navigate to the root of the server’s Runtime MBean tree
serverRuntime()
# navigate to the JMSRuntime
cd(‘JMSRuntime/myserver.jms’)
# first navigate to the destination “MyQueue1”
cd (‘MyJMSServer/Destinations/MyJmsSystemResource!MyQueue1’)
# create a cursor to get all the UOO messages from the queue that
# belongs to the UOO named “my_uoo” that are currently
# in “ordered” state.
# Note 1: The third argument value represents the ‘state’.
# Note 2: To get all the ordered messages that may belong
# to more then one UOO, pass the first argument as ‘true’
cursor1=cmo.getMessages(‘JMS_BEA_UnitOfOrder LIKE \’my_uoo\’’,9999999,16)
# next find the cursor size
size=cmo.getCursorSize(cursor1)
# print the size value
print size
# delete all the messages belong to UOO “my_uoo”
# Note that this deletes both visible and invisible messages of the
# given UOO
# To delete all the messages pass ‘true’ as the first argument
count = cmo.deleteMessages(‘JMS_BEA_UnitOfOrder LIKE \’my_uoo\’’)
# print how many messages are deleted
print count
Hope this helps,
