How to monitor jms queues

Hi,
I want to monitor JMS queues in a way that if the pending messages increases some limit, i should get alert may be through mail or some message.
As in the application message load is so much and due to some delay in response from some resources(external application) the messages in the queue start increasing and the "Pending Messages" for the queue start increasing as shown in weblogic server.
Thanks in advance
-Abi

This is a monitoring function. And, monitoring functions are not specified in the JMS specification. For Sun MQ 4.x (don't remember which one), the monitoring functions are accessible through JMX. For other products, see your admin guide.

How to configure JMS queue on OC4J server. Development in JDeveloper 10G

Hi there,
I have to configure a JMS for an Asynchronous process in my Application which will be running in Oracle 10G Application Server. Development Environment is Oracle JDeveloper 10G.
I am facing a problem on how to configure JMS queue.
Steps Followed are:
in the <JDevloperHome>/j2ee/home/config
1. Made the new queue and connection factory's JMS entry in jms.xml.
2. Specifed the queue in oc4j-connectors.xml.
3. played around with application.xml
and tried all combinations, but the message producer always failed to lookup the queue.
Need help on the steps to follow so that the producer can post the message in the queue.
Also please help how to configure the MDB to listen to the queue.
Thanx and Regards
Subham

If you were dealing with Oracle 10g app server as opposed to standalone, I might be better able to help you.
One thing though, when you are configuring your MDB in the orion-ejb-jar.xml file, do not forget to specify attribute listener-threads, otherwise no matter how many beans you have in your MDB pool, only one bean will be listening to the queue. Many listener-threads equal to max number of beans in pool.

How to delete JMS Queue using WSLT thru JNDI?

How to delete JMS Queue using WSLT thru JNDI?

Hi,
You can use the following WLST script to delete the queue :-
edit()
cd('/JMSSystemResources/MyModule/JMSResource/MyModule')
startEdit()
cmo.destroyQueue(getMBean('/JMSSystemResources/MyModule/JMSResource/Mymodule/Queues/MyQueue'))
activate()
Is it what you are looking for?
I hope this helps.

How to manage jms queue?

How to manage jms queue. I want to do operation on messages on jms queue like deleting the messages and hold the message for some time . Please provide the sample code for that.

Thanks a lot Tom for the reply, I have read about the descriptor setting 'max-beans-in-free-pool' and I searched this concept at the Administration Console without success.
I suppose other way is create a “Session Pools” under the JMSServer, and then create a “Consumer” and define the setting “Messages Maximum”. One of the disadvantages is that “Session Pools” don’t support JTA, from the documentation:
+Session pools enable an application to process messages concurrently. Session pools are now used rarely, as they are not a required part of the J2EE specification, do not support JTA user transactions, and are largely superseded by message-driven beans (MDBs), which are a required part of the J2EE specification.+
I continue reading the MDB chapter of the performance and tuning guide in the documentation, thanks for any contribution to the topic.

How to create JMS Queue in soa 11g?do we need to create jmsuser user in db

Hi All,
We r using SOA 11.1.1.3 version do we get jmsuser user while installing itself. we r unable to see this user. Can anyone suggest how to create a JMS queue in soa 11g.
Thanks,
RR

Hi,
Oracle SOA runs over weblogic application server 10.3.3
If you want to create a JMS queue, then you have to create it on weblogic server. For creating a JMS queue, first of all create a JMS server on weblogic admin console (by default http://localhost:7001/console) (Services --> Messaging --> JMS Servers) and target it to a server/cluster as desired. Now create a JMS module (Services --> Messaging --> JMS Modules) and target it to same server/cluster.
Now create a sub-deployment in JMS Module (Services --> Messaging --> JMS Modules --> Your JMS Module --> Subdeployments tab) and select the JMS server you created initially as a target of this subdeployment.
Now create a connection factory in that JMS module and in advanced targetting select the subdeployment you created. Now create a JMS queue in the same JMS module and in subdeployment select the subdeployment you created.
If you want to access this queue from an application then JMS URL should be like -
jms://hostname:port/connFactoryJNDIName/QueueJNDIName

Anuj

How to Check JMS Queue in BPEL

Hi All,
we have a case where SOA shows message is successfully sent to TIBCO, But it is not available in TIBCO queues.
We have the property file used by BPEL for different instances and the JMS queue mentioned are different for different instances.
So how to check to which TIBCO queue SOA sent message through BPEL.
Rgds,

Based on the JNDI look up used, you can determine the instance. Iam not sure this is the right way but you can try this.
Thanks,

Is there any configuration to get aound this?
Or do I need to use following code inside of my web application?

How to create JMS Queues and Topics - OAS 10.1.3?

Hi,
Is there a way to create JMS Queues and Topics via the command line for OAS 10.1.3, say through admin-client.jar ?
I have read the "Managing Adminitered Objects" chapter from the "Oracle Containers for J2EE Resource Adapter" book and could not find the information I am looking for.
Thanks.
-Sachin

Hi Sachin --
In the 10.1.3.1 release, a set of new commands have been added to admin_client.jar to support the command line creation of JMS resources:
-addJMSConnectionFactory -domain <domain> -jndiLocation <jndiLocation> [options]
-removeJMSConnectionFactory -jndiLocation <jndiLocation>
-getJMSConnectionFactories
-addDestination -domain <domain> -name <name> -jndiLocation <jndiLocation> [options]
-removeDestination -name <name> [options]
-getDestinations
You can read about it in the doc:

How to access JMS queues in the SAP J2EE Engine?

Hi Gurus,
Can anybody know how to access the jms dead message queues in the XI J2EE Engine (which is WAS 6.40)?
I have read in the SAP documentation that we can use some JMS commands from the telnet. I don't know how to use those commands.
Can anybody provide a step-by-step process to access these queues?
Thanks
Kalyan

1) Open a command prompt
2) type
telnet localhost 50008
where the port is the same as your http, but with 8 as last digit.
3) Login
4) Issue the following set of commands
jump 0
add jms
jms list deadmsgs
Check by man jms other possible options.

How to config JMS queues for non-AQueue products? Only config files?

Assume I have the requirement NOT to use Oracles built-in Aqueue JMS provider but use another (external)product like:
Apache ActiveMQ, JBossMQ, IBM MQseries,... instead.
Can I config these JMS products through OC4Js web browser config web pages as well or am I forced in such cases to use configuration through XML config files?
How do I tell OC4J NOT to use internal JMS Aqueue queues but use other JMS product?

How to monitor weblogic Queue

Hi,
we are using weblogic Queue for storing messages .
Recently we are facing an issue , when the incoming messages are more then our Queue went down
So the question what i am asking is that , if the Queue goes down , can we get any sort of indication ??
Thanks for reading .

hi,
you can define the threshold and quota for the queue, using that you can define the minimum and maximum
queue meessages,.
if it reaches the threshold it will send a notification and it wont allow for new message, it will avoid you to goes down your queue..
you can use weblogic.WLST to check your JMS parameters,

Create jms queue xml data server

Hi,
What's the difference between jms queue and jms queue xml data servers and how to create jms queue xml data server.
Thanks.

Hello,
JMS messages can principally be processed by Oracle Data Integrator in two formats:
- JMS Messages: containers for rows of data, handled through JMS Queue/JMS Topic Technologies. With JMS Queue/JMS Topic technologies, each JMS destination is defined similarly to a flat file datastore. Each message in the destination is a record in the datastore.
- XML Messages: containers for XML files, handled through JMS XML Queue/JMS XML Topic Technologies. With JMS XML Queue/JMS XML Topic technologies, each messages payload contains a complete XML data structure. This structure is mapped into a relational schema (XML Schema) which appears as a model. This use the Oracle DI Driver for XML (see the driver documentation in Oracle DI documentation).
Find below a step by step creation process for such a destination:
1. Data Server
To create a JMS XML Queue data server, you declare a simple JNDI connection. The only JMS XML specific information is added to the URL. This information defines the XML file format.
The JNDI URL should be : <JMS_RESOURCE>?d=<DTD_FILE>&f=<XML_FILE>&s=<SCHEMA>&JMS_DESTINATION=<JMS_DESTINATION_NAME>
- JMS_RESOURCE: JNDI resource corresponding to your JMS queue that will contain the XML payload. You would specify this URL if you were managing normal JMS messages.
- DTD_FILE: path to a DTD file that describes the XML structure. Mandatory if the parameter XML_FILE is omitted.
- XML_FILE: path to the XML file with a structure similar to the expected XML messages. Mandatory if the DTD_FILE parameter is omitted.
- SCHEMA: schema name that will contain the XML structure. This value must match the one set for the physical schema attached to this data server. This parameter is mandatory.
- JMS_DESTINATION_NAME: name of the JMS queue or topic. This parameter is mandatory.
2. Schema
Creation is straightforward: In the Schema (Schema) and Schema (Work Schema), enter the name of the <SCHEMA> defined in the data server JNDI URL.
3. Model
Use standard reverse-engineering. As the Oracle DI Driver for XML is used the XML structure will be reversed as a relational structure.

JMS Queue monitor

Hi Experts,
We have a requirement in PO 7.31 system to monitor the message traffic for sender and receiver jms queues defined in communication channel configurations. These jms queues are managed externally by EAI team.
Please let us know how to do this , if it is possible in PO 7.31 single stack system.
Best Regards,Prasanth

Hi Prasanth -
We have a requirement in PO 7.31 system to monitor the message traffic for sender and receiver jms queue
>>> You can monitor the message processing in PI i.e. if the messages are being successfully processed to JMS queue or not. You can configure the alerts to receive email in case the messages gets failed in PI.
Michal's PI tips: Component-Based Message Alerting
However i don't think we can monitor if they are being processed/failed by your JMS application.

Monitoring jms distributed queue on WebLogic 8.1 via MBeans

Good afternon,
please do you have someone java code (only basic enough !) for jmx monitoring jms distributed queue on weblogic 8.1 (Monitor all Active JMS Destinations and there Consumers, Consumers High, Consumers Total and so on..). Think should be used JMSDestinationRuntimeMBean interface but have no idea how write the code.
