Message Selector MQ

Hi,
          My MDB reads messages from a MQ Queue. I have set up MQ as foreign JMS Provider.
          I want to read only messages with JMSXGroupID = "".
          Does somebody can help me out with this?
          Thanks,
          Ravi Ambati

I guess this would work.
Multiple types of messages in a single MQ Series

JMS Header: JMS Properties and Message Selector

Hi all
I´m using a JMS Adapter to consume messages from a JMS queue (a JMS adapter which create the BPEL instance when a message arrives).
The process must select messages which meet certain criterias, so I´m using Message Selector to filter the messages and only pick up the ones who interest me (If click on the "help" button on JDeveloper Wizard in the page you define Message Selector, you can see an example on how doing this).
So how can I select messages using values placed on JMS Properties, in the Message Selector?
For example, I set in the JMS Header:
JMSInboundHeadersAndProperties
--------JMSInboundProperties
----------------Property
-----------------------name = 'Country'
-----------------------value = 'Brazil'
The JMSAdapter must consume only messages that "Country" = "Brazil".
Thanks in advance.

I am able to specify JMS Header and JMS Properties when producing a message. However I am not able to user "Message Selector" to filter messages based on JMS Properties information when consuming messages.
In the link you provide, there is an example on how to use Message Selector:
# (a copy from the link)
Message Selector
...for example, you can enter logic, such as:
* JMSType = 'car' AND color = 'blue' AND weight > 2500
* Country in ('UK', 'US', 'France')
I believe the example with "Country" is exactly what I need, but I can´t get it work.
I create the same example above, setting a property named "Country" in the JMSHeader, sending the message to a JMS Queue (BPEL Process #1) and try to comsume it on the Message Selector (BPEL Process#2), but JMSAdapter never consumes the message.
Thanks for your help.

Message Selector and Setting JMS Header Properties PL/SQL Enqueue

Currently I am attempting to use the Message selector functionality. I just know know exactly how we need to set the property in PL/SQL when enqueuing. I also want to verify the syntax that I should use in the event that I am doing this incorrectly...
The code I am using to test the enqueue is
declare
enqueue_options dbms_aq.enqueue_options_t;
message_properties dbms_aq.message_properties_t;
message_handle RAW(16);
agent sys.aq$_agent := sys.aq$_agent('', null, null);
message sys.aq$_jms_text_message;
recipients DBMS_AQ.aq$_recipient_list_t;
BEGIN
message := sys.aq$_jms_text_message.construct;
message.set_text('<ORDER><HEADER_ID>16992531</HEADER_ID></ORDER>');
message.header.set_string_property('bamfilter','ORDER_ENTRY');
dbms_aq.enqueue(queue_name => 'XX_OM_MONITOR_Q',
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle);
COMMIT;
END;
we have tried a few other methods, but still to no avail...
the syntax I believe for the selector in the ems should be bamfilter='ORDER_ENTRY'
Any help would be great.
The DB the Queue is locate is on 10g if that makes any difference...

JMS Adapter Message Selector Problem...

Hi
I have set the following in the invoke before producing the message and dropping on the queue
<invoke name="Invoke_1" partnerLink="adapt"
portType="ns1:Produce_Message_ptt"
operation="Produce_Message"
inputVariable="Invoke_1_Produce_Message_InputVariable"
bpelx:inputHeaderVariable="Sender"/>
On the receive side I have the message selector configured for the adapter as follows:
<jca:operation
ActivationSpec="oracle.tip.adapter.jms.inbound.JmsConsumeActivationSpec"
DestinationName="dattjndi"
UseMessageListener="false"
MessageSelector="Sender=AdaptationRequest"PayloadType="TextMessage"
OpaqueSchema="false" >
</jca:operation>
Where AdaptationRequest is the value for the Sender variable which will be used to filter the message. But this does not work. the messages are still not consumed. What could be the problem?
Thanks,
Anil

did you check the message selector section on
http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/jms/Message.html
explains all the operators you can use and the correct syntax. Make a note of the case sensitivity.

Trouble using JMS Message Selector and DCJMSMessageProperty0

Hello Experts!
My scenario is Mainframe => MQ => JMS Adapter => XI => SAP
My MQ channel is communicating fine to XI and I've set the JMS adapter to JMS Compliant.
I have multiple message types with consistent headers but varying data layouts that I need to route to different mapping objects. So it seems the best solution for this is JMS Message Selector based on reading a header value from one of the dynamic message properties.
I've read SAP Notes and SAP Library and SDN Wiki articles about this configuration and I think its possible.
http://help.sap.com/saphelp_nw04s/helpdata/en/10/b1b4c8575a6e47954ad63438d303e4/frameset.htm
Note 856346 - J2EE JMS Adapter: Frequently Asked Questions (FAQ)
Note 1086303 - XI JMS Adapter and IBM Websphere MQ: FAQ
https://www.sdn.sap.com/irj/scn/wiki?path=/display/xi/usage%252bof%252bmessage%252bselector%252bfor%252bjms%252bsender%252badapter
My mainframe sends an MQ message that includes some extra header information like
field: ApplType VALUE: 000000002
field: ApplName VALUE: MIS056O
I configured my Communication Channel to set Adapter-Specific Message Attributes and also Additional JMS Message Properties to include ApplType and ApplName.
However, I can only see some of the standard JMS header items such as CorrelationID, none of the additional ones.
In RWB I see "JMS property 'ApplType' that corresponds to dynamic header 'DCJMSMessageProperty0' is missing from JMS message 'ID:f2f0f0f9f0f4f2f1f0f9f1f5f5f3f7f44040404040404040'; consequently it cannot be added to XI message 'e136a6e8-8580-4adc-2007-9ccab93f1ef4' as a dynamic header"
Can anyone with some experience doing this help me see if I'm missing a trick somewhere? How can I see where this information is being dropped? Could it be when MQ is handing to JMS?
Many thanks,
Aaron

After sifting through some IBM documentation I found that the PutApplName field actually maps to JMS name JMSXAppID. So after adding this to my Additional JMS Message Properties list I get the dynamic JMS message property I need for sorting out the messages.

JMS message selector

hi there,
any one used JMS message selector field in the JMS sender adapter. I want to filter out messages that are relevant for various interfaces. where do i set the filter value. i read java docs, it says the filter is possible for message header and properties. the weblog on sdn is not exactly clear and it doesn't work either.
thx

Ya you can go ahead with it right ??? See it says you can filter on the basis of header info and its properties , so header info will have originating source info. Its worthful to use it that way . Please clarify if i am wrong , i think thats what u require filter msg on basis of interface for what you are using the adapter.

JMS Sender adapter Message selector

Does anyone know of a good blog where someone is showing how to use the JMS message selector option in the JMS sender channel? I'd like a screenshot of what is actually typed into this field most of all.

JMS Message Selector on Message Payload

Hi,
I have a requirement where in;
A JMS adapter consumes messages from an AQ JMS Topic. We need to make selective dequeue from the Topic. Is that possible to make use of the message selector option on the 'message payload'?
Message selector works on JMS Header and Properties as far as I know.
Any insight on this would be of great help :-)
Thanks,
Manoj Nair.

It's like almost a month to get a response for such a generic JMS functionality. Looks like the Oracle SOA user base is really low. Anyone with a working example reference.
Thanks

AQ Adapter with message selector rule

Hi,
I'm doing a B2B11g implementation on AS2. Incoming messages are processed using the AQ adapter. Now I have several (about 8) AQ-adapter implementations on the IP_IN_QUEUE that select messages using a message-selector-rule based on the DocumentType. So each SOAComposite dequeues and processes the appropriate document.
This works fine, but I'm looking for any performance recommendations on this.
What is the impact on CPU for example using message selector rules? Any do's and don'ts on this?
Thanks in advance.

Martien

A basic query with respect to using Message Selectors in JMS

Hi
When i am going MEssage Selectors topic in web , it seems very confusing for me .
I have written a simple JMS Application based on Weblogic as my Queue .
I have two Java Files one for Message Producer and another file acting as Message Consumer using MDB
I have a basic TextMessage with some header properties in my Producer file .
Please tell me in what file should i put MessageSelector ??.
Thanks for reading .
Please clarify my query on this .

Thank you very much .
I found the code of a MDB making useage of a Selector .
*<message-driven>*
* <message-selector>shirtType = 'polo'</message-selector>*
* </message-driven>*
Assume that i written a MDB that listens to particular type of Messages (Polo in this case ) .
Please tell me what happens to other messages in the Queue that were never listened by the MDB .
Thank you .

Question about Message Selector

Dear all,
I have implemented a JAVA progrram which will sent 10 JMS messages into AQ sequentially, and then use another JAVA client which will get JMS message from the AQ.
I found out that if i use Message Selector to get message from AQ, the message will NOT be read from the queue by enqueue_time, how can i get the jms message from AQ by message selector that can preserve the enqueue_time order?

Have you got a lot of MTA?
Because you can create one rule by MTA...
Example:
In message filter:
verylongbloke sayed how do that...
and in content filter:
rule1: if (header("X-IP") == "^1.1.1.1$") { alt-mailhost ("[1.1.1.1]"); }
rule1: if (header("X-IP") == "^1.1.1.2$") { alt-mailhost ("[1.1.1.2]"); }
It's not very sexy but it works fine...
unfortunately, we can't use variable for alt-mailhost action... or I don't know how :)
regards..

How to use timestamp based dynamic message selector?

Is it possible with message selector to issue query like statement that
weill fetch any messages that have header timestamp older than "now" + 3 hrs.
In SQL you would say something like:
where timestamp <= sysdate + (180/1440)
Please let ne know.
Thank you,
Edmon

hi edmon,
to my knowledge dynamically evalutaed expressions like this are not supported by any of the JMS vendors. messageselectors are in SQL92 format and the only dynamic part in them is the contents of the message properties and headers.
So, you're out of luck with what you want to do (e.g., remove expired messages from a destination when they havent' been consumed within a time threshold??) but i could see two possible solutions:
1) You could use time-to-live (TTL) on the sender side. Messages that are on the destination beyond their TTL would be placed onto a dead message queue (DMQ) from where you could consume them for further processing. DMQ is not a standard-JMS feature but supported by a few vendorrs (e.g., JBoss, ArjunaMS).
2) You could use Message-driven Services (MDS) for more elaborate server-side message processing. MDS has been pioneered by ArjunaMS but is also available with a few other JMS vendors.
Hope that helps!
Kind regards,
Thomas.

Problem using Message-Selector

Hi,
out client-application subscribe to a JMS-topic on OC4J (9.0.3) using the following code
TopicConnectionFactory oConnectionFactory = (TopicConnectionFactory) ctx.lookup("jms/MyTopicConnectionFactory");
oConnection = oConnectionFactory.createTopicConnection();
oTopicSession = oConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
Topic topic = (Topic)ctx.lookup("jms/MyTopic");
TopicSubscriber sub = oTopicSession.createSubscriber(topic);
Everything works fine.
But when we replace the last line to use Message-Selectors
TopicSubscriber sub = oTopicSession.createSubscriber(topic,"username = 'abc'",false);
we get the following (strange) error (which occurs at excactly that line)
javax.jms.InvalidDestinationException: Invalid topic
The topic can't be invalid, because we could subscribe without Message-Selector. Do I have to modify the topic at the JMS-Configuration? Any ideas?
Thanks,
Gilbert

Hi Gilbert,
The way I've done it is by defining the rule when creating the subscriber in the database (thru DBMS_AQ). The following document might give you some insight.

OSB JMS Message Selector / Filter

HTTP PS and JMS BS puts messages on WLS JMS Queue. We need consume some messages from the Queue based on payload content since interfaces for other messages may go Live in next year.
JMS Message look like
<Schools>
<School>
<Id></Id>
<ServiceArea>100</ServiceArea>
<Type></Type>
</School>
</Schools>
We need to consume messages where ServiceArea = 100.
Can you advise how to consume messages where ServiceArea = 100 ?
I would appreciate your help.
Thanks in advance.

JMS message selector on message payload fields is not recommended and it will have performance implications. Instead you can design this in either of the 2 ways below
1 - Modify the HTTP PS which publishes the message to set the JMSCorrerlationID header ( or any othe custom JMS property) with the value of Service Area. You can achieve this using Transport Header action in HTTP PS route node.
For the JMS consumer proxy set a message selector on the JMS transport page to filter only messages belonging to this service area.
2. Let the HTTP PS continue publishing all messages to the output queue. Have a new component in your design called a 'disaptcher' which reads all the message from the output queue, check service area tag and route messages belonging to particular area to an area specific queue. Have your jms consumer specific for service area 100 to listen to only this Area specific queue.

Experiences using the JMS Message Selector

I am using a JMS Adapter Sender Communication Channel and try to select the messages I want to consume with the Message Selector. My first attempts all failed - I am not sure if the syntax I am using is correct or if anything else has to be set up to use the Message Selector.
My sample was to enter the following into the field for Message Selector:
JMSCorrelationID = '123456789012345678901234'
I also tried the following variations:
JMSCorrelationID = "123456789012345678901234"
JMSCorrelationID = 'ID:123456789012345678901234'
JMSCorrelationID = "ID:123456789012345678901234"
but none of them were successful.
Anybody got that feature to work yet and can help me...
regards,
peter

Now I found it out finally...
JMSCorrelationID = 'ID:41727469636c655570646174656400000000000000000000'
where ID: is obviously added by JMS? XI? don't know... and the actually id is in Hex...
can anybody enlighten me on the details?
regards
Peter

Dynamic Message Selector

I am faced by a requirement where I need to be dynamically keep changing the message selector's defined on the MDB's, without redeploying them.
Is this possible to do ? and if yes can someone point me in the right direction or give me some examples on how to do this ?
Thanks,
AA

Hi Ankit,
Did you make out how to implement message Selector. I have the requirement and i stuck up . If you suceeded, i need help.
