Message Redelivery and specifying a maximum retry count

I am using JMS calls to receive messages from a queue. When I want to rollback, I can call the queueSession.rollback() function and the message is redelivered to the queue.
Right now it will try to process the message again and again and keep on rolling it back. I would like to specify to only retry processing the message 3 times and then do something else.
I noticed when I do a System.out.println(jms.Message) it displays all the message properties including JMSXDeliveryCount. There is however, no get method to retreive that value.
Does anyone have any idea of how to control message retries?

Fault policy and jca.retry.count in 11g

I have a composite which has the architecture as follows :
Adapter (File) -- Mediator -- Adapter (FTP)
The mediator follows sequential routing pattern
I have configured jta.retry.count = 3 for the FTP adapter.
Also the composite refers to the fault policy file from the MDS
In the fault policy file the ora retry action is defined as follows :
< Action id="ora-retry">
<retry>
<retryCount>1</retryCount>
<retryInterval>5</retryInterval>
<retryFailureAction ref="ora-rethrow-fault"/>
</retry>
</Action>
We have configured the following rejection handler for the file adapter :
<faultName xmlns:rjm="http://schemas.oracle.com/sca/rejectedmessages"
name="rjm:FILE_RD_B2BOutFolder_Files">
<condition>
<action ref="ora-ws"/>
</condition>
</faultName>
We get the following message as part of rejection message email notification :
The adapter has exceeded maximum configured retries. The adapter has exceeded maximum configured retries. The adapter was unable to process "{0}" after having retried for {1} times, now the adapter will reject the message. This exception usually comes due to errors in downstream systems. Please increase the value for "jca.retry.maxRetries" in composite.xml for the inbound service and redeploy.
I have the following doubts:
1. When the FTP adapter fails because of a remote fault, which retry will be executed fault policy or jta.retry.count ?
2. If the jta.retry.count is executed then can I see 3 instances on the EM console or any other entry in the Log file.
3. where can i configure jca.retry.maxretries property. this property is not available on emconsole.

Hi,
Section 12.4.4 and 12.4.5 should answer your questions.

Message retry count for the message has been exhausted

Hi,
I am using 'Custom Document Over Internet' with HTTPS as transport protocol. I have set the acknowledgement mode to Sync in order to receive the synchronous response. B2B is able to post the HTTP request successfully and in turn it receives a synchronous response and a MDN message. At the initial stage, after posting the request it shows the state as 'WaitForAck' for request message and for response and MDN messages, the state is completed.
After some time when we check the state of request it is changed to 'Error' with the error message as 'Message retry count for the message has been exhausted'. We have not set the retry count and retry interval and so after retrying for 3 times with an interval of 120 minutes it is showing error state as it is not able to correlate the incoming response to the corresspoding request. We have tried the option of setting the Message id of the request in 'replyToMsgID' parameter of response header and tested the flow. But still I am facing te same issue. Please help me to resolve this issue.

Hi Anuj,
The property mentioned by NandaGopal has already been added in tip.properties file. I sent the B2B logs in debug mode and tip.properties file to your mail id. Please have a look into that. The result of opatch lsinventory command is

Retry count JMS message on Proxy Service

I have a proxy service listening to a JMS Queue.
It is a task service. I need to try some functionality. If an error occurs (probably because of an offline external service/ business service) I need to rollback and retry). I want to do this for example 5 times. If this fails I want to send it to an error queue
I see the JMSXDeliveryCount going up. I though I could set this with the retry count field. But I see now it is for the response queue.
The only way I can solve it is to put an error handler and look at the JMSXDeliveryCount . If it is above the number of retries I stop reraising.
Is there another way?

If you choose the service type as WSDL based or Any SOAP service, then OSB engine will deconstruct the incoming SOAP Envelope and populate the parts of envelope (Header, Body etc) to correct context variables automatically. This happens before the message flow of proxy service is initiated, so you can not do anything about it. In the proxy service you will receive the deconstructed SOAP message only.
If you do however want to log the exact message which was received by OSB, then change the service type to (or create another proxy service in front of the existing proxy) Messaging type with binary or text content. Or you can also choose AnyXML service type, in which case the incoming SOAP Envelope will be available inside $body variable in message flow.

Message Retry Count Zero error

Hi,
I am sending a Message from one Trading partner to another over ebMS protocol .
The trading partners are using Weblogic JMS queues as the internal delivery channels.
when one trading partner is sending message to another, the mesage comes to the receving trading partner with error as "Max retry count for Message is zero".
I have reffered to one of the thread (Re: FTP retry issue) which says "Can you please update the Retry count and time to acknowledge in the<br />Delivery channel page and update the polling interval in the transport<br />server page as empty? I think the Polling interval value overrides the<br />retry count."
I have followed this and I am getting a Transport Error.
Please Help!
With Thanks & Regards,
Suhas.

Retry count and retry Interval fields in Business service (Http protocol)

Is retry count and retry Interval in OSB business services(Http protocol) defined for retrying the application errors or for communication errors?
Also even if my connection timeout is 0 I get an error response due to communcation issue in abt 2.5 mins.
Please explain.

- There is an explicit configuration on business service called "Retry Application Errors", if enabled application errors will also be retried.
- If timeout is not set on business service then domain level timeout configuration comes into effect which is by default of 180 sec i.e 3 mins.
Hope this helps.

Maximum record counts and property counts

Hello,
I am looking for the document/link that mentions maximum record counts and maximum property counts for each record.
let say there are 1.5million records and each record has 2000 properties. Not sure if it can be handled nicely.
Mdex version is 6.2.1 at this point. but can upgrade if higher version can handle more.
Thanks,

Jeremy is pretty much correct. There are no limitations except by performance.
Start with the Performance Tuning Guide - here is a link to the 6.4.1 document:
http://docs.oracle.com/cd/E41223_01/Mdex.641/pdf/PerfTuningGuide.pdf
For your questions, start with Chapter 5 and read how properties/dimensions affect performance and this will help drive how you architect your queries and pipeline configuration/index setup to be most efficient.

Can someone please help me!! I keep trying to download itunes but get a message that and error has happened 2/3 and check window activity. Then it shows A sever with the specified host name could not-- and then it cuts off the rest of the message.

I keep trying to download itunes in Safari but get a message that and error has happened 2/3 and check window> activity. Then it shows A sever with the specified host name could not…… and then it cuts off the rest of the message. I have reset Safari and still nothing!!!

It's downloading with Firefox 3.6.27 as I write. It's probably more a Safari problem in your case for which people on the Safari forum could provide suggestions. Or mybe just try again in a while as I suspect everybody is downloading right now.

Powershell: Count total messages to and from external domain

Hi All,
I'm attempting to get a count of total messages to and from our clients domains. For example, @customer1.com 23.
So far, I have the following code
get-messagetrackinglog -start (Get-Date).adddays(-1) -resultsize unlimited |where-object {$_.EventID -eq

What I'm looking for is the following:
If the Sender or the Recipient is NOT @ourcompanydomain.com, count total messages either sent or received from the domain. Output to csv.
123.com, 53
456.com, 32
Any help would be greatly appreciated.

DB adapter retry count value

Hi gurus,
I am using a db adapter for polling options. The option used is 'Delete the row(s) that were read' .
Here the retry count by default is set to unlimited. Is this the recommended one? In normal db adapter options i see the retry count as '4'
the property value seen in composite.xml is shown below
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>
Will this lead to any performance issues? Or what could be the correct retry count value?
Please let us know.

Hi,
We have used the polling options using Logical delete vastly in our project and never faced any performance issues with respect to this property value being set to 'unlimited'.
I believe there should not be any performance issues with respect to the 'Delete the row(s) that were read' option as well.
According Oracle documentation:
In the Auto-Retries section, specify the value for auto-retry incase of time out. In case of a connection related fault, the Invoke activity can be automatically retried a limited number of times. You can specify the following values in the fields in this section:
To retry indefinitely, type unlimited in the Attempts field.
Interval is the delay between retries.
Backoff Factor: x allows you to wait for increasing periods of time between retries. 9 attempts with a starting interval of 1 and a back off of 2 leads to retries after 1, 2, 4, 8, 16, 32, 64, 128, and 256 (28) seconds.
Thanks,
Deepak.

How to increase maximum channel count?

Hi,
i have a big problem with my director app.
I create for a game(dots and boxes) 300 objects by using a
parent skript. Each generated Sprite takes his own channel. But
director offers only 150 channels so i can only add 150 Sprites.
Does anybody have an idea to increas the maximum channel
count.
-- Edit
Oh, sorry. I have found the option in the settings. 1000 is
the highest.

modity>movie>properties
In the property inspector at the movie tab there will be an
entry for
channels. Change this number.

Diff activAgent jca.retry.count vs partnerLinkBinding prop.retryCount?

When I look into the bpel.xml of some BPEL projects I can find two similar parameters:
In <partnerLinkBinding ...> there can be a
<property name="retryCount".....>
A couple of lines below in the <activationAgent> section of bpel.xml there is sometimes a similar
<property name="cap.retry.count=....> value
Mind the dot between "retry" and "count"!
Whats the difference?
Peter

Hi Peter,
Can you post complete bpel.xml...
Basically as of my knowledge the retries for jca activation agents are for... If you take File adapter, and in that if we mention some xsd for the input message and the input message you are getting is not compatable with that xsd, it will fail....In that case first it will try number of times mentioned in the activation agent level times.

Retry count & interval problem

I am Using OSB R4 where My Scenario is i need to place the payloads in to the JMS Queue, and route them to the Endpoint URI webservice if the service is unavailable i need to sent the notification mail and rollback the payload back in to the Queue. My problem is i receiving hundreds of notification mail when the service is down instead of one. I configured the retry count to 1 and retry interval as 15 mins for the business service URI and implemented single thread consumer in work manager. Please help me in this.....

I am Using OSB R4 where My Scenario is i need to place the payloads in to the JMS Queue, and route them to the Endpoint URI webservice if the service is unavailable i need to sent the notification mail and rollback the payload back in to >the Queue. My problem is i receiving hundreds of notification mail when the service is down instead of one.This is a classic case for using OSB SLA alerting instead of doing it in the message pipeline. Configure a sla alert set to trigger when there are 1 or more route errors in an aggrevation interal of 30 mins and set an email alert destination. This will make sure you will get only 1 mail for all errors in that period of 30 minutes.

Re: Constant Message Redelivery Problem

You can get redelivery for other reasons as well. Redelivery occurs if the message is
          participating in a transaction, and the transaction fails for any reason.
          For example, if the MDB in turn calls an EJB which in
          turn calls JDBC then the tx becomes two-phase. If the JDBC call fails then the tx
          will roll back. Or if the tx times-out: the default tx timeout is 30 seconds, so if
          the MDB takes longer than 30 seconds then the tx will roll-back and message the will
          get redelivered.
          Even if the tx succeeds, in some cases you may have error states that re-enqueue the
          received message but let the transaction commit (WLI, BEA's integration product, can do
          this).
          This looks like the redelivery of a failed message, but is actually the delivery of a new
          version.
          Duplicates occur if a Queue MDB's descriptor actually points at a topic destination.
          Check for this one by comparing the JNDI name in config.xml against the
          descriptor destination type field...

And make sure that your MDB is not throwing Errors or RuntimeExceptions,
          as these don't necessarily get logged, but they cause rollbacks.
          Put a "try {} catch (RuntimeException re)
          { log; throw re; } catch (Error er) { log; throw er; }"
          around all the code within the MDB's "onMessage()" callback
          to see if this is happening.
