Error with JMS receiver channel

Hi,
We have a scenario in which Order response will be sent from ECC to WebLogic (JMS system) through PI.
After the restart of JMS, we are facing issues with JMS receiver channel.
Some of the responses are delivered, and for few we have the error as described below.
Also, one of the cluster node of the JMS receiver channel has the below error.
Please anybody throw some light on this.
Error description:
" Delivery of the message to the application using connection JMS_http://sap.com/xi/XI/System failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: Pending message discovered: dfff2e2b-80f5-94f1-a068-001cc4d99b3e.The channel is configured throw an recoverable, temporary error for this warning (default). Decide whether you want to bypass this message. If so, set the Pending Handling channel parameter to 'Bypass' and restart the message afterwards.. "
Thanks in advance.
Regards
Bhanu Tiruveedula.

Hello Bhanu,
we have been getting this error from long time with JMS channel but no solution except changing the configuration so that it can throw exception and move on.
we have also noticed that this happens for some time and then gets resolved automatically. so it seems to be some data which is not expectable by jms channel.

Ratna

Error in JMS receiver channel

Hi,
I have a JMS receiver channel which is connected to message queue of TIBCO which is working fine.
But if I use the same channel after a day it goes into error and after restart of the channel it again works fine.
Error: Message process failed. Cause: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Unable to write newJMS Message body for message: 343241-......... Connector Exception: ... session ended..
Thanks,

Hello Aravind,
I have made similar experiences while accessing JMS queues.
Maybe the JMS queue was not available for a short time. So the receiver channel could not connect.
Best regards,

Hi Manju
There could be some problem while deploying the libraries. please check you have deployed the JAR Files correctly.
You need to include the Weblogic Thick client driver 'weblogic.jar' - with all classes under the package 'javax.jms' removed in your aii_af_jmsproviderlib.sda (releases 3.0/7.0) or com.sap.aii.adapter.lib.sda (releases 7.1).

Sync/Async communication with JMS Receiver

Hi all,
I am working on one Sync/Async model without BPM. Sender is RFC which is expecting some response, but we know receiver jms doesnt support response message directly. For this i used modules provided by SAP.
While developing interface i used below objects.
One Outbound Synchronous interface--> for Sender RFC channel
Inbound Synchronous Interface----->for Receiver JMS Channel
outbound asynchronous interface--->for Sender JMS channel
one request mapping and one response mapping
Operational mapping between outbound Synchronous to inbound synchronous.
ID Objects:
2 sender agreements: one with sender jms channel
one with sender rfc channel
1 receiver agreement: with jms receiver channel
1 receiver determination
1 interface determination
In receiver jms and sender jms channels i used modules as specified in the document http://help.sap.com/saphelp_nw04/helpdata/EN/45/20d2b4c20a0732e10000000a155369/content.htm
But my interface is not working end to end successfully.
Please confirm below points
1)do i need to have other external application put response message to response queue or will the MQ automatically generates the response message and put into response queue
2)In receiver jms channel is it ok if i will put response queue(Q2) name in the field JMS ReplyTo Queue Name or do i need to put in the form queue://<ReplyToQMgr>/<ReplyToQ>
3). what is the format of data type for asynchronous outbound interface which i used for sender agreement of jms sender channel.
4). Do i need to do any other special settings at MQ settings in MQ server.
Note: i am using PI7.1 and i selected the option JMS-compliant for target client in jms channels.
Thanks,
Madhu

1)do i need to have other external application put response message to response queue or will the MQ automatically generates the response message and put into response queue
The following information is available in SAP note-
Message correlation implies correlating a response message with a request message. With respect to the JMS adapter, this means that you sent have sent a message through a JMS receiver channel to some JMS queue (say queueA) , some external application processes this message and puts the response onto another JMS queue(say queueB) which is then picked up by a JMS sender channel. You need to relate this response message with the original request message.
In the simple case, for all JMS compliant providers this can be done in a straightforward manner:
a) In the JMS receiver channel configuration, set the JMSCorrelationID to the XIMessageID. (or some other XI header which is applicable)
b) Ensure that your external application does not change the value of the JMSCorrelation
c) In the JMS sender channel configuration, set the XIConversationID to the JMSCorrelationID
d) The XIConversationID header of the response XI message now contains the XIMessageID of the request XI message.
For some providers such as Websphere MQ in legacy/native mode this is not so straightforward.
Do i need to do any other special settings at MQ settings in MQ server.
If your using Websphere MQ, refer que#4 in sap note :1086303

Error with the Receiver JMS Adapter (Connection On-Demand feature)

Hi,
In high volume we are experiencing errors with the Receiver JMS Adapter and the connection On-demand feature:
Adapter Framework caught exception: while trying to invoke the method com.sap.aii.adapter.jms.api.connector.DisconnectorListener.notifyEvent(java.lang.String) of an object loaded from local variable 'listener'
Delivering the message to the application using connection JMS_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: while trying to invoke the method com.sap.aii.adapter.jms.api.connector.DisconnectorListener.notifyEvent(java.lang.String) of an object loaded from local variable 'listener'.
The message status was set to WAIT.
Looks like the message is successfuly reprocess after the wait period but the ALEAUD/Akcnowledgment are not successful in the sender ECC system. (SAP -> PI - > JMS)
Any idea?

Hey All,
Following is the solution for the above mentioned JMS receiver channel problem whilst connecting to MQ Series Server.
I assume you are connecting to a MQ series server with version less then 7.xx, or MQ Server 5.xx,
Cause of Problem: The problem appears when you try to send a message through JMS Receiver Adapter channel to a such MQ server and at that particular moment, the server do not accepts the message i.e. the connection with MQ Server drops out; resulting in a Java null pointer error, as the MQ fails to assign the pointer back to the same message, { again until its transferred to MQ.} therefore MQ JMS 2003, MQJMS2007 and MQJMS1016 error appears.
Possible configuration at XI/PI:
1. Add a Advanced additional JMS parameter Connection_Test_Poll = True
2. For XI settings from the drop down of field "Handling of Pending XI messages" select "Bypass Pending Warning and Send Message to JMS(Duplicates possible)" . This will probably cause duplicates at MQ series Server side, make sure you are ready to encounter it there!!
3. If the error still appears, choose In the Error Handling settings, Reconnection if Exception text Starts with provide the error number which the message is currently experiencing. eg. MQJMS1016 or MQJMS2007 or MQJMS2003. Restart the communication channel and restart such message..
After applying the above settings if you still experience errors MQJMS2007, 2003 and MQJMS1016, when connecting and processing messages to MQ server, Then you should try upgrading the MQ Series server! You cannot do much in the XI/PI system else you will create duplicates in the MQ system.
Please Note this error has more to do with the compatibility issue of MQ Series server with PI's JMS adapter.
Do let me know if you have any more queries on this.
Regards,
NIPUN

JMS Receiver channel EOIO

Hi,
In SAP help, for one of the parameters of JMS Receiver channel it is mentioned that:
Delivery Mode of Message Producer :
Specify the quality of service of the message producer. You have the following options:
u2022 Persist JMS Messages in the JMS Provider
u2022 Do Not Persist JMS Messages in the JMS Provider
Does this means EOIO/EO. I have proxy to JMS scenarios & like to send the data to JMS in EOIO.
We are using Transport Protocol " Access JMS Provider with JNDI"
With this I want to achieve, EOIO for Proxy to JMS. Pls let me know if Delivery Mode of Message Producer parameter would help & what should be the value.
Thanks.

Exactly Once messages are handled by default using status information in the J2EE server. All adapter error statuses and program terminations initialized externally are also handled in this mode. i.e.
= persist jms messages in the jms adapter.
Now if you specifically want to have dedicated queue; check manage queues under SXMB_ADM.
See if you can set dedicated queue to your interface so that the messages can be processed in the sequence they have received.
Also, once it is out of PI into target system (queue) the order will be maintained.
Cheers!

Error in JMS Communication Channel not raising alert

Processing Errors in JMS Communication Channel are not raising alerts.
The settings on the communication channel retires are set at 3 and 5min interval.
In RWB the JMS communication channel shows processing errors but an alert is not raised.
The alert are configured in our system and we even have a catch all alert rule with * (wildcard). Errors in PI message processing are raising alerts but errors in Comm Channel are not raising alerts.
The message in SXI_MONITOR shows as processed successfully but when we check the RWB and Comm. Channel Monitoring we see processing errors "Channel error occured; detailed error description: JMS error: Connection to the server has been terminated; Linked error: Connection reset, Error Code:null"
Are we missing any configuration? How do we get alerts/notifications if there are errors in Comm. Channel without having to login into RWB and watch it periodically?
Any help is greatly appreciated.
RM

Hi,
What is the staus of Communication channel in RWB when it fails, RED ??if yes then it should genarate alert.
create one more alert for specific to JMS interface and check it out.

Heartbeat possibilty in JMS receiver channel?

Hi,
Does anyone know if it is possible to define a heartbeat interval in JMS receiver channels.
Is there maybe a possibility in the additional JMS paramters fields?
We need this to prevent connections being shut down by firewalls due to long inactivity. Once a JMS receiver channel is inactive due to this there is no automatic activation of the channel possible (I think).
The sending JMS channels pose no problem since XI AF seems to poll these every 5 seconds and thu sthe connection remains alive.
thanks
Tom

Hi Shai,
We are using XI 7.0 with SP 12 and we entered this parameter in advanced settings in JMS receiver adapter called "CONNECTION_TEST_POLL" as true and it does the polling to see if the adapter is active...
Hope this helps.

TJ

JMS Receiver channel : No Correlation ID

Hi,
JMS Receiver channel to WebSphere MQ,
I want to put a message on the queue with correlation ID left blank (= no correlation ID), because this causes problems on the receiving side.
Is there a way to achieve this?
I have tried several different settings, but the message appears always with correlation ID.

Hi Manikandan,
Check the username and the password for the FTP server. If the username or the password is wrong then you would be able to post the message.
Also, there might be a timout issue, In the timeout parameter enter some value.
