Channel stopped polling

Hi,
I have two channel configured that uses file adapter to pull files from a ftp server.The general settings in both the channel -FTP parameters,Processing parameters with a polling interval of 300 secs, are same.Both differs only in the specific settings - Content conversion parameters.
But the problem is one channel polls the server every 300secs,but the other not.
This is behaving like this for the first time because it used to poll regularly some time before.
I have checked for the queues,no LUWs.
Refreshed the cache in SXI_Cache - Delta refresh
As a temporary solution,i'm start/stopping the channel every time i saw files piled up in the server.The channel picks all the files seen in the server at the time of restart but after few seconds it fails to poll again,and a restart is required every time the file not picked.
I'm a newbie to XI.Please could anyone help me.
Note : the directory from which it is pulling the file is loaded with too many irrelavant files.Could this be a problem.

The status is green : Communication channel is correctly configured and started
The details seen in CC monitoring for the channel with problem:
Last administration: Started at 5/30/07 7:00:15 AM
No error information for administration is available

File Sender channel stopped polling on FTP site

Dear all,
We have many file to Idoc interfaces running in production and all are they good.
Yesterday we faced one issue, one of the interface's sender communication channel stopped polling and didn't picked the files from FTP.
There was no error on communication channel monitoring and it is green.
We stopped & started the channel then started picking the files. But this is not usual behavior of file adapter.
We found one SAP Note 1083488, according to this note, we are in the latest SP level( PI 7.0 SP 14). So not required to apply this patch my case.
What should i do to not to face next time

Hi Bhavana,
Check the below Q & A.....
>> Q: After configuring a large amount of File Adapter sender channels, the J2EE Engine becomes very slow and some services start to block. How can I solve this issue?
A: Up to and including XI 3.0 SP13 each File Adapter sender channel permanently consumes a J2EE application thread. To solve this issue, increase the number of configured J2EE application threads using the SAP J2EE Engine Config Tool ("cluster-data" -> "Global server configuration" -> "managers" -> "ApplicationThreadManager" -> "MaxThreadCount").
Starting with XI 3.0 SP14 / PI 7.0 application threads are allocated on demand by the File Adapter and returned to the thread pool after it has finished the polling sequence, so thread shortage situations will typically occur much more rarely than with earlier SPs.
Also as said by Other SDN'ers check the locks.
Thanks,

JDBC and FTP sender channels stop polling

Hi,
We have a great volume of sender JDBC and FTP sender channels.
For this reason there is nothing unusual to have temporary error connections.
Several months ago, with an XI 3.0 system, sender channels recover its functionality automatically when temporary error connection is solved.
But now, he have migrate to a PI 7.1 sytem, and in the same scenario and configuration, sender channel stop polling after a temporary error . In cc monitor this channels remains in green status and there were no signs of stopped interfaces.
Timeouts are correctly defined and there is no difference between channel configuration in our Xi and PI system.
How to solve this problem?
Thanks, in advance.
Carme.

Thanks for your fast response, Stefan.
After writing this post, i ask the same question to our basis team and we are in the latest sp.
¿do you know if there is any note or can you provide me some additional information?
I'm not able to find any note about this issue...

Sender JDBC - Stops polling

Hi All,
For some of the sender jdbc channels, we face locking issue. The channel monitor keeps showing same log 'processing Started'. Based on sdn threads, we tried to remove the jdbc lock in Netweaver Administrator. But it didnt work. As per the sap note
Note 1083488 - XI FTP/JDBC sender channel stop polling indefinitely(04/04S), planning to try with taskTimeOut parameter.
But what is the optimal value to be given for this parameter? Then could the Transaction Level be kept to Default? Hope it will not lead to any message loss.
The PI version is 7.1 and service pack level is 4.

Hi Aarthi
According to JDBC Adapter Note 831162.
Q: During JDBC receiver message processing I see that some messages are in "delivering" state forever. How do I solve this?
A: Please set the receiver channel configuration Exactly Once handling parameters as "local" and "redo". The configuration setting "local" and "error" setting is some times prone to deadlock situations at the DB table level.24.
Also check question 28 in SAP JDBC Adapter Note 831162.

Reg: How to Stop Polling of JDBC Adapter without Scheduling the adapter

Dear Gurus,
Here I am having one requirement. My clients wants to send data from JDBC adapter (ORcale System table) to R3 system via RFC.
His Requirement::
1. He is not telling the time of data flow from Oracle server so that based on that we can schedule the adapter in the Communication Channel monitoring (Availablitiy Time Planning) or Else we can Schedule by deciding the setting of the polling interval time.
2. He is telling that When ever he waants to send the data he will place one dummy file in the File Adapter FTP location so that it will became an Indication for u to poll the jdbc adapter and to transfer the data to R3.
3. Untill he keeps the file or gives indication he doesn;t want to communicate with Oracle server due to some security and it s a most important data base he doesn't want to disturb that Oracle Server as so many business are running on that.....
We Proposed::
1. Atleast you need to tell the scheduling time or poll interval time so that we can schedule our adapter.
but he s not accepting for this
2. Atleast U need to give access for Data base to enter one more extra field like STATUS CODE so that we will add one number and we keep on Update in the Update table and based on that Update table statement it will poll.
but he s not even accepting for this
3. Finally we prposed that to create another table in the Oracle SYstem as Dulplicate Table which is similar to Standard Orginal table when ever he wants to pick the data please keep that data in this Duplicate TABle so that JDBC adapter will pick the data from thsi TABLE instead of picking the data from that standard table so that it will not effect any standard table data in the table.
but he s not even accepting for this
We have done some R & D:::
1. WE approached even through BPM and via switch conditions is one scenario
 FILE RECEIVE >SWITCH CONDITION> RECEIVE AND SEND or else EXIT
2. Using correlation in anotehr scenario means correlating File adapter and JDBC and based on one dynamica value it will goes to SEND STEP ( RECE IVE --> RECEIVE --> SEND STEPS )
Even though we know this...concept that...we jsut tried::
In BPM we can control the flow in XI 3.0 but we cannot Stop the Polling of JDBC adapter at backend because one the data comes from FILE adapter it will keep on HOLD untill it receives the JDBC from Oracle then based on the condition or Correlation it will goes futher SEND step means after that file adapter is picking file or not ...what ever it may be JDBC will polls at backend and brings that data to BPM"
Hence sugest me How to Stop Polling of JDBC Adapter without Scheduling the adapter or else using STATUS CODE Update statements in JDBC Tables

Amar Srinivas Eli

Hi! All,
Finally I decided to do the scenario in two steps:
1: FILE REQ --> JDBC REQ -->JDBC RES --> FILE RECV
2: FILE RECV --> RFC
But I am getting issue while doing first scenario
Desgn :
I have created 2 Synchronous interfaces :
1) FILE 2 JDBC REQ
In this a) out put message is FILE Req
 b) Input msage:; FILE RES
2} JDBC2FILE RECV
 a) Output mesage;; JDBC REQ
 b) Input Msge :: JDBC Response
Mappings:
1) File REQ-->JDBC REQ
2) JDBC RES-->FILE RES
Interface mappings:
1: FILE 2 JDBC REQ--> JDBC 2 FLE RECV
CONFIGURATION ::
1: One Seder File CC
2: Two reciever CC's one is for JDBC RECEIVER and other s FILE RECEIVER
3; One Sender Agreement
4: 2 Recver agreements
5: One Interface Determination and
6: One RECCV Determination
My Question;;
1. First let confirm whether my development steps are right or not ?
2: Another thing s I am not sure reg Configuration Steps means
whetehr one interface determination and one Receiver Determinations are required or not as these are synchronous Interfaces
3: main Issue is::::
If my scenario s FILE2RFC2FILE then I will get RFC response automatically but here issue is this is JDBC
My reqquirement is By sending one Field from fILE to JDBC REQ it needs to send entire TAbLE records as a Response to file as XML
without having Sender JDBC how can I send the JDBC Res to FILE and If that is the case then again JDBC adapter is polling which is contradict to the client requuirement which i explained above.
pleas suggest me the Detailed steps mainly Colloboration agreements and logical routings and
also explain in detail if i can go for BPM
Also give cleear blogs but before giving make sure that it contains detailed screen shots because aIready gone thorugh
Scenario File-JDBC-RFC
File<-->JDBC Sync coomunication.

Sender JDBC channel stop send messages

Hi,
We have a sender JDBC scenario which is working correctly time ago.
However, sometimes this channel stop sending messages although the Adapter Monitor shows that they regularly execute the polling interval.
We have confirmed that there isn't any connection from XI to target BD.
In other ocasions, we are required to restart XI and, after that, this scenario works without any problem.
What could be the cause?
How to solve it?
thanks, in advance
Carme

This is rather strange.
A few of my observations -
1. When the sender jdbc adapter polls , and there is no data matching the select query, you will still see a message id in Comm Channel Monitoring but with no hyper link.
2. The actual message id / message is created only if there is data in the database and also the hyper link is enabled.
3. If you are confident that the data is being commited on the database and that it is XI not pulling the right data, one issue might be - driver issues. Can you check if you have the right compatible drivers for your database on XI server - is there a new'er driver available?
We hit a similar issue with JMS adapters and we learnt that the JMS server had been updated as a result of which a new driver had to be installed which we did not until we hit intermittent problems like these.
Hope this helps

Sender File adapter stops polling

Hi All,
We have a strange issue. A sender File (NFS) communication channel which was working fine, suddenly stops polling.
The cache, is upto date. There are no errors in the channel monitoring. In fact the polling logs are being recorded in the RWB showing successful polling. But the channel does not pick up the file which is lying in the file location. Channel has been working fine till then.
Finally we had to create a new communication channel with the same configuration which picked up the file instantly.
Is this a known issue with File adapter and is there a solution to prevent this situation from happening.
Regards,
Sathya

In fact the polling logs are being recorded in the RWB showing successful polling. But the channel does not pick up the
file which is lying in the file location. Channel has been working fine till then
Did you checked if the adapter was locked out? Normally this is the reason....happens with FILE and JDBC....channel shows successfully processed but there is no message that is actually passed.
Needs to unlock the adapter from VA....SAP Note available mentioning this problem.

Abhishek.

Sender communication channel stopped after error "Connection Timed Out"

Hi experts,
in our scenario we have an asyncronous sender communication channel with polling every 6 seconds to an external FTP server.
Yesterday evening a "Connection Timed Out" error came.
After this error the polling stopped but channel in communication channel monitoring still remains green.
So status green but no polling.
To solve this problem we stopped and then restarted channel from CC monitoring.
The channel is configured "manually".
The question is: Is it possible to avoid this problem? Maybe there's a parameter in configuration to set?
After a time out error the channel must go on polling, it should not stop. Or it must shows red status.
Thanks

JDBC Comm Channel not Polling data

Hello,
In a JDBC to IDoc scenario, we have a sender JDBC communication channel which was set to poll for data in every 60 sec. It was working fine for long and suddenly it has stopped polling data. It's status was green and the channel was active.We couldn't find the reason so we configured one more comm channel keeping all the parameters same, and it has started working. We couldn't understand why it was not working earlier. Can any body please highlight on this?
Regards,
Sugata

Hi,
@Barry,
Yes, it dont poll data from database although it was supposed to do so. We have tried to make some changes and then undo changes and save+activate. But that hasn't work.
@ PT Rao,
We tried that too, that also hasen't work.
@ Sumit,
could you please elaborate?

JMS Sender Channel not Polling

Hi Guys,
Scenario: BEA Weblogic -
> JMS Queue -
> Sender Channel JMS -
> SAP XI -
> SAP R3
We had initially setup this scenario using MessageSelector because the provider JMS Queue had mutiple message types on it. As Murphy's law would have it, the MessageSelector stopped polling the day before go-live. Basically, if we pointed one JMS SC to the provider JMS Queue using MessageSelector it worked fine, if we pointed multiple JMS SC's no messages were being picked up from the queue. We still haven't identified why the MessageSelector functionality stopped working but as a quick work around to MessageSelector before go-live we used blog:
[/people/robert.warde3/blog/2009/03/18/pi-basics-generic-message-interface|/people/robert.warde3/blog/2009/03/18/pi-basics-generic-message-interface]
Now we have a situation where, BEA Weblogic manages the provider JMS Queue & they perform a health check 4 times a day & if they encounter a problem they bounce the server & JMS Queue service. XI and the SC seem to re-connect fine most of the time when Weblogic & JMS Queue is back up but there are times when I see a green light in RWB for the SC but it's not polling for messages on the JMS Queue. We use Hermes JMS to monitor messages on the Queue to check if there are in fact messages to be picked up & the messages are queued.
What I'm looking for is a best practice guide for how to manage this. I don't want to keep toggling between Hermes JMS & RWB to verify if the SC is in fact polling messages altho' it shows as green in RWB. Please advise. Thanks.
Regards, Trevor

Thanks Kai & Joel.
Joel, I'm not really looking to add another layer with the JMS Connector Service. For me it's just adds another possible point of failure. At the moment the message passes thru 5 systems including SAP R3 & end system & then the response comes back the same route.
Going out from SAP, the Receiver channel to the JMS queue seems to work fine. With the responses coming back, the Sender Channel seems to re-connect ok (I'm assuming) otherwise it wouldn't be green in RWB but doesn't pick up any messages. It's also an intermittant phenomenon. Manually stopping & re-starting the Sender Comm Channel fixes the problem but we won't know if there's a problem until we check if messages are being picked up from the queue.
Kai's notes led me to some things I could possibly look at like additional parameter in JMS channel config, CONNECTION_TEST_POLL (note 948016). I'm still not sure how we can make this work for us because we essentially need to bounce the JMS channel so it starts polling again in the event of a JMS Queue Provider bounce but I need to first establish that the JMS Queue was bounced.
Note 1088675 will also be irrelevant cos the channel looks like it re-connects, just doesn't poll.

JDBC adapter stop polling at a particular time

Hi,
I am facing one issue with J2EE engine of Xi. Everyday at 11:59 pm JDBC adapters stop polling. If we look at communication channel monitoring in RWB there will be a green light against these communication channels. But if look at the cluster node, we can see that the channel is not polling data from the database.
Once we restart the J2EE engine it will start polling records from database. Why it is stop polling at the this particular time? Can you please give some suggestions to resolve this issue.
Thanks

FTP Adapter stops polling on updating descriptors in BPEL Console

I have a bpel process activated by a file in a FTP dropzone. An FTP Adapter listens to this dropzone. I have set up a few preferences (Deployment descriptors) for this process. Once when I update any of these user defined preferences, ftp adapter stops polling the dropzone.
Any idea why this happens?
Workarounds?

Hi Shishir,
Bouncing the server working most of the times, which might not be possible all the time in case of production environments ;/

Hi Senthil,
As suggested by others there is no problem with your communication channels ,,, the problem you face is because Your DBA has initiated the SHUTDOWN IMMEDIATE command. This will shutdown Oracle and terminate all active operations.
Please tell him to start the services and Wait until Oracle has been restarted by your DBA.

Error in SOAP sender CC. Channel stopped by administrative task.

I am getting an error in my SOAP sender communication chanel as follows;
com.sap.aii.af.ra.ms.api.DeliveryException: XIAdapterFramework:GENERAL:com.sap.aii.af.ra.ms.api.DeliveryException: Channel stopped by administrative task.
The channel is Active but still gets the same error. Any help would be appriciated.

RWB ---> Component Monitoring ---> Adapter Engine ---> Communication Channel Monitoring ---> Choose your CC and check its properties....check if it shows Channel Stopped...if yes then restart it.
Channel should be Active in ID and Started in RWB to work properly.

PI 7.1 File & JMS Adapter stops polling at random times

Hi All,
IN PI 7.1, at random times, the File Adapter stops polling. But status is green in RWB.
It starts working after the restart of File Service.
Any idea why this happens? (We don't use FTP Protocol)

Yes Ravi. We recently migrated to PI 7.1 from PI 7.0.
We dont use AAE.
We are on Support Pack 7.
"Adapter Framework is changed in handling threads on the backend in SAP PI 7.1"
what impact it might have on the File Polling?
