OSB JMS proxy. Determine when processing is complete
Basically, I need visibility into how many rows the JMS adapter is processing and when it is complete.
I am doing a simple request\response proxy where the response is a second queue. Basically, it just moves messages from one queue to another.
In our case, the source queue will be paused until a specific point in time where we resume it and let OSB process all the messages. I need to know when the process is complete. Anything I put in the pipeline is executed for each message.
Any ideas?
Thanks,
Sam
You don't have to check for every message. Why don't check once a minute or so? Alternatively, you can enqueue a special "finished" message and check for it in your proxy.
Or you can try to describe what you need in more details. ;-)

Trouble finding way to determin when video is complete
here's the url to this project:
http://www.mespinach.com/picNpic/
A video starts playing when project loads. Button ONE pauses the video and places a smaller video over the first video. When this second video completes I would like it to be removed and the first video resumed. As it's currently written I have to use button Two to accomplish this task.

Hi ,
can i use a Proxy service with out a Business service to write a messge onto a queue.I jus tried a sample on my local and i am able to write a message on to a queue using a proxy service .
Flow :-
PS1(http) using publish action invokes -> PS2 (jms uri config)
I am clue less how this is working.when the PS2 transport has been defined as jms ,how am i able to invoke it from PS1 using publish action?
My understanding of OSB is ProxyService is for reading message from queue and Business service is for writing or publishing a message onto a queue.
can some body help me udnerstand how this is working.Basically, you're right when it comes to the difference between business and proxy services. Also, you're not the only confused when routing data from http-based proxy to JMS proxy.
We touched the topic earlier:
Re: Retry mechanism for HTTP Transport in OSB
The point is your layout (HTTP PS -> JMS PS) is sound and works even without intermediate business service. -

I keep getting the below error in the log file when the process is complete, does any one has this error before? The error does not affect the process but it is kind of annoying when looking at the log file.

OSB JMS Proxy XA Transaction Rollback not occuring to queue
Hi All
We are dequeuing a message from JMS queue via an XA connection factory and then calling a web service. If any error occurs in the web service we catch the error handler, log and notify it and want to send this message back to the queue for retrial (The retry settings are defined at the Queue Level from weblogic console).
Problem is rollback is not occurring, we have tried the below:
1) There is no OSB reply with either success or failure in the error handler (This should have done the trick)
2) We have also tried addiing an explicit Raise Error (Uncaught Error) to roll the message back, but its not working.
This rollback is not occurring because JMS Resource is XA and web service call is NON XA, hence the entire message flow becomes NON XA. Is this understanding correct?
How can we fix this? Please helpHi atheek1
Thanks for the reply, it worked. Before I mark this question as answered, pls. answer the below queries (Thanks a lot!)
1) Well, i just ticked transaction required and same transaction for response and it started working. I did not add routing options like you mentioned to QOS Exactly Once. Its working without it fine. So, my questions is what is the use of adding this QOS to exactly once. Is it mandatory?
2) I have a couple of OSB services in which rollback is working automatically (XA JMS to JCA FTP Adapter) and (XA JMS to JCA DB adapter XA data source), here rollback works automatically. I dont have to tick transaction required. So my question is, when an XA based connection factory picks a message from the queue, a transaction is started at the container level. So why tick transaction required at the message flow level, when the weblogic has already initiated a transaction. Since you said that HTTP transport commits a transaction even if 500 or 404 occurs, it makes sense to tick is transaction required and same transaction for response in OSB proxy service. But the remaining scenarios work without these options. Hence will it be wise to say that these settings are only required for HTTP transport coz of the way it behaves (commits 404 and 500).
Thanks -
OSB jms clustering - load balancing seems to be not working
Hi All,
I have one admin server and two managed servers running ( one of these managed server is running in the remote linux machine) in a cluster
I have connectionfactory created with load balance enabled with round robin
and server affinity is disabled
I have queue created as uniformly distributed Q
I have a proxy service with load balancing as roundrobin and endpoint URL as below
jms://rdoelapp001011:61703,rdoelapp001013:61703/synergyConnectionFactory1/MM_gridQ0
If I execute this proxy sending messages it always go to one server only. There is no message going to the other server.
If I shutdown the server that receives messages then the other server is receiving messages. Seems like fail-over is working but not the load-balancing
There is one point may be worth mentioning here is, from the admin console if I look at the servers for the clusters it has below information
Name State Drop-out Frequency Remote Groups Discovered Local Group Leader Total Groups Discovered Group Leaders Groups Primary
synergyOSBServer1 RUNNING Never 0 synergyOSBServer1 1 synergyOSBServer1 *{synergyOSBServer1}* 0
synergyOSBServer2 RUNNING Never 0 synergyOSBServer1 1 synergyOSBServer1 *{synergyOSBServer1, synergyOSBServer2}* 0
one server has groups as {synergYOSBServer1} instead of {synergyOSBServer1, synergyOSBServer2}. Does that look correct?

Any help will be greatly appriciated
Edited by: 818591 on Feb 16, 2011 11:28 AMI am not getting you here "the right approach is to make OSB run on the man server cluster and not on admin server. "
I have a jms proxy service that I created from admin console
And also I have gone thru the step 5 in the link below
http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/deploy/config.html#wp1524235
If I am not wrong, the proxy service endpoint URI determines where it is pointing to. If it is a cluster environment, it should point to a clustered address
My proxy has below endpoint URI
jms://rdoelapp001011:61703,rdoelapp001013:61703/synergyConnectionFactory1/MM_gridQ0
and rdoelapp001011:61703,rdoelapp001013:61703 is my cluster address
As per your suggestion "To fix your problem, *make osb to run on the cluster* and specify the same URL for the jms proxy service"
Could you please provide some instruction how would I "make osb jms proxy service to run in a cluster"
As a note, I have Q defined as a distributed Q and connection factory targets to the cluster. UDQ also targtes to the cluster.
Just for a testing I have created another manged server running local to the machine where my admin server is running
And I created a proxy by following steps as I mentioned above and with endpoint URI as below
jms://rdoelapp001011:61703,rdoelapp001013:61703,*rdoelapp001011:61700*/synergyConnectionFactory1/MM_gridQ0
where the new address of my cluster is rdoelapp001011:61703,rdoelapp001013:61703,rdoelapp001011:61700
It did create consumers in both the managed servers in the cluster that are running locally, but no consumers in the remote managed server.
So I am kind of leaning towards thinking that there is some incorrect setup for the remote managed server and may be admin server is not able to communicate to the remote server for some reason but not sure about it..
As a note the cluster is setup to communicate using "unicast" channel
and I created a channel in each manged server with the same name
here is the cluster configuration
<name>synergyCluster1</name>
<cluster-address>rdoelapp001011:61703,rdoelapp001013:61703,rdoelapp001011:61700</cluster-address>

[OSB] Invoking OSB HTTP proxy as a part of a global transaction
Hi,
my question is, can a OSB HTTP proxy be executed in context of the global transaction?
I did two tests. One had the following scenario:
HTTP OSB proxy invokes JMS OSB proxy that invokes an "Insert to database" business services.
Both of the proxies were transactional - I have set "Transaction Required" and "Same Transaction For Response" to enabled on both of them. Also, I've set QoS to "Exactly Once" in the Routing Option.
The OSB JMS proxy's flow was executed as a part of the global transaction. I confirmed this with the following test:
If I throw an exception in the responce pipeline of the HTTP OSB proxy, the database transaction was rolled back. If I throw an exception in the responce pipeline of the HTTP OSB proxy, but have the "Transaction Required" and "Same Transaction For Response disabled, the database transaction is commited and than the exception is thrown.
The problem is, If I change the protocol of the second proxy to HTTP, then it doesn't seem to be executed in the context of the global transaction. If I throw an error in the response pipeline of the first OSB proxy(and "Transactions Are Required" and "Same Transaction For Response" are enabled for both proxy, and QoS is set to "Exactly once") the database transaction is not rolled back.
So, can a OSB HTTP proxy be executed in context of the global transaction?
Edited by: user13604541 on Dec 5, 2011 2:27 AMI have read on OSB doc that HTTP proxies do not support transactions... your tests seem to confirm this.
-
I was hoping that someone can clear my understanding of OSB and how it interacts with JMS.
I created a JMS server, connection and topic in WLS. It works great. I am able to subscribe and publish from a java client and from an OSB business service.
Our use case is to use OSB as a "front end" to JMS if you will. We want JMS clients to be able to connect to OSB and subscribe to our JMS topic (durable). Is it possible to subscribe to a proxy service from a JMS client? How do I do it?
The next thing we are going to try to do is have an OSB process listen to our JMS topic and invoke a web service when a new message is published. Any guides on this?
Thanks so much,
SamWe want JMS clients to be able to connect to OSB and subscribe to our JMS topic (durable). Is it possible to subscribe to a proxy service from a JMS client? How do I do it?I don't think subscribing to a proxy service is possible. Instead create a separate queue (or any other storage), for your client application and let OSB pull the message from source queue and pass it to target storage (may be another JMS queue)
The next thing we are going to try to do is have an OSB process listen to our JMS topic and invoke a web service when a new message is published. Any guides on this?This approach is quite similar to what I mentioned above. Just create a JMS proxy service to let it consume messages from topic and create a Business Service (WSDL based web-service) to invoke the target web-service. In the message flow of JMS proxy you may have transformation if required, and then route the message to business service which will eventually deliver the message to target web-service.

When to use a JMS Bridge and when to use a Proxy
Hi,
We currently are running an OSB with most connections coming in via MQ to a JMS queue. We've been asked to implement a JMS Bridge.
Wen using a messaging bridge to a foreign provider, the documentation recommends using the Foreign JMS option to simplify the creation of bridge destinations anyway.
The key difference with using the bridge, is that you remove responsibility for the network transfer of messages from OSB's proxy and give it to the bridge. However, this now means that the messages are stored in WebLogic JMS with all the implications that brings. Is that really what you want? Isn't the whole point of MQ to be your reliable messaging service and not to use WebLogic JMS instead/as well?
But the Solutions design team mention
Without bridge
MQ >--------Receive -------->---------Send ---------> JMS
| ....... Transaction 1 ....| .....Transaction 2 ......|
With bridge
MQ >--------Receive -------->---------Send ---------> JMS
| ....... ............Transaction 1 .......... ......|
Is this true, so we have to use a bridge?I think your solution design team is wrong..
MQ --> OSB Proxy Receive ---> OSB Proxy Send --> JMS will be a single XA transaction.
An OSB proxy is preferred in this case for the following reasons:
1. Don't use bridge for receiving messages . Bridge should be used rather for sending messages to non highly available remote messaing providers. Even for this case weblogic recommends SAF .
2. Whatever the savings on transaction as mentioned by your design team doesn't appears to be correct.
3. Weblogic messaging bridge appears to be a buggy product. You will have to apply a couple of patches to make the bridge to work as expected. It will take some time to stabilise it in a production environment. Weblogic's EJB container is much stable and with MDB's it would be less prone to bugs. This is from my personal experience. Others might have a different experience.
4. You can leverage the out of box monitoring facilities provided by OSB. This can give you stats of how many messages were transferred between MQ and JMS, average & max response time etc. -

OSB -11g - Calling JMS Proxy Service in a stage
Hi,
When we createa JMS based proxy service, the proxy service keeps on polling the JMS Queue for any new messages arriving in the queue. But I do not want the proxy service to keep on polling the Queue. Instead I want to call the JMS Proxy Service in any stage (of any other Proxy Service) using a service callout. It means that I do not want the Queue to be polled always, instead the queue should be polled only when this JMS Proxy Service is invoked.
Is it possible to do? If so, how?
Thanks,
SanjayHi Anuj,
Following is my requirement:
The producer wants to interact with us using Web Services. The input payload has some more values (username and password) apart from the HL7 data (base64 encoded) itself. I have to receive the input payload, authenticate the call and convert the HL7 encoded message into an XML and send it to the consumer.
What have I done till now:
1) I have created two Proxy Services PS1 and PS2
2) Proxy Service (PS1) will be invoked by the producer.
3) Then I get the username, password and data from the payload
4) Populate the username and password in the SOAP Header and HL7 data in SOAP Body
5) Call PS2 from PS1
6) In PS2 I have configured Message Level Security to authenticate with the username and password
7) After authentication I make a Java Callout to decode the base64 encoded HL7 data
8) I now have written my own HL7 sender (Java code) which wraps the decoded HL7 data with MLLP requirements and then send it to the B2B server using a Socket (TCP connection). I do a Java Callout to this Java class.
9) In B2B I have configured a RTP (Remote Trading Partner) which has a MLLP channel.
10) I created a ADT message document and a ACK document
11) I created two agreements between HTP and RTP (one agreement receives the HL7 data from the TRP using MLLP and another which sends the ACK to the RTP using MLLP channel)
12) In the receiveing agreement I have configured a JMS channel (on the HTP side) becuase of which B2B receives the HL7 Pipe delimited data and translates it and then pushes the XML data into the JMS queue (which needs to be transformed to producer XML)
13) I have also configured a JMS channel for the RTP which I am using in second agreement to get the acknowledgement. Because of this the ACK is placed in a JMS queue.
I need to poll this JMS queue in order to send the ACK back to the producer (which I have to do in the response pipeline of PS2). Hence I wanted to pop the message from the JMS queue in the response pipeline and then send that message.
Please advice if my approach is correct.
Thanks,
Sanjay

OSB 1031: proxy service and publishing JMS messages with no duplicates
Hi all,
we have a Web Service proxy that publishes messages into a JMS queue. The queue is persistent and the related connection factory is XA enabled.
The proxy does the call to the JMS business service from a route node.
If a failure occurrs after the publishing returns successfully, the caller receives back an error and it will try again to call the web service proxy.
As the message has been published successfully and was not rollbacked by the proxy, the second call could put on the JMS queue a duplicate message.
As far as we know only with JMS proxy service, OSB starts a transaction within the pipeline or are we wrong ?
What do you suggest in order to avoid such a scenario described above ?
Thanks and regards
