DB Adapter stops polling

Hi,
We have several processes which are initiated by a DB adapter polling a database table (oracle.tip.adapter.fw.agent.jca.JCAActivationAgent). Recently, the poller processes stopped activating for about a day, then started working again.
When the problem started, we had just run out of space in the BPEL dehydration database (one process reported a "cannot extend tablespace" error). The problem was resolved after we resolved the tablespace issue. Is this the cause - even though the table being polled is in a different database? All the evidence points to that, but I want to be sure.
thanks,
Michael

Hi Shishir,
Bouncing the server working most of the times, which might not be possible all the time in case of production environments ;/
Do you find any errors on the logs when the cube engine and activation loggers are set to DEBUG ?
Could you please mail me your project to [email protected] ?

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?

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.

what impact it might have on the File Polling?

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.

JDBC Adapter stopped polling

Hi,
our JDBC Adapter is stopping polling automatically.
It seems if the adapter does not process an event for a long time. The adapter is stopping polling.
Can somebody help me?

hi,
can you try using:
<b>"Disconnect from Database After Processing Each Message"</b> indicator
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
on your test system to see if the same will occur ?

DB Adapter stops polling intermittently

Hi,
We have been observing that the DB adapter on our BPEL 10.1.3.4 ( MLR#9) process manager stops polling the database every now and then.
We then have to kick-start it by updating the POLLING_INTERVAL property on the descriptor page via the console ( This property has been explicitly exposed to control the polling interval from front-end).
Although this has been observed pre-MLR#9 as well we are still unable to find the cause behind this. If anyone has faced a similar problem can you please share your experience and possible resolutions for the same as well.
Thanks,
Shishir

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

Hi,
Get into Config tool >> Cluster_Data -Instance -Service -Com.sap...jdbc.svc...
And check whether you have defined as Always or Automatic..

FTP File adapter stops polling

We r using SAP PI 7.0
In File FTP adapter we had set 120 sec polling interval and timeout parameter 120 sec
I have seen 1083488 sap notes even , it shows this patch..
PI 7.0 SP12 ADAPTER FRAMEWORK CORE 7.0
Support Package 12, Patch Level 3 (SAPXIAFC12P_3.SCA)
Can anyone tell more about this error resolution...

Check whether the Adapter Engine is working fine(In RWB). check your coummunication channel in RWB channel monitoring
May be your channel is locked. See this 1083488

Biztalk2009 - OracleAdapter stops polling if Oracle server has been booted

We are running a two node Biztalk2009 and use (among other adapters) an Oracle Adapter, we are on Cumulative Update 4 on both BizTalk Server and Adapter Pack. It happens that someone boots the Oracle server and this seems to make our Oracle Adapter stop
polling. Even after the Oracle server is up and providing data our Biztalk Oracle Adapter no longer polls so we no longer receive relevant data even when they are available on the Oracle. Currently we overcome this by restarting the relevant Host Instances
but this is impractical. So anybody know if there is a way to make the Oracle Adapter keep polling even if an Oracle server is down and not providing data for a while ?

Hi ,
Its Always a best practise to STOP your Polling receive location or reshedule your Polling Interval during the period when downstream System Goes Offline .Due to concurrent failure for polling,BizTalk will keep the receive Location aste to Passive until
you restart the application.
Thanks

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.

How do you know that the DB Adapter has stopped polling

Hi,
Is there a smart way to figure out if the DB Adapter has stopped polling a table ? [We are using logical delete polling strategy].We are looking for a better alternative than just verifying the entire laundry list of tables for the markUnreadValue after every polling interval.
rgds,
Ram

Thank you for your post. Although this is a feature for Buzzword, right now it's not possible to know if someone has viewed a file you've sent via Share. We are working to integrate Share/My Files/Buzzword so that this will be corrected in future.
Let me know if you have additional questions.

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
Regards

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,

SFTP Adapter Stops picking files intermittently

We are having issues with sftp. In the BPEL process we are polling for files from a sftp location. When we deploy this process, it picks the files
perfectly but after some time(couple of hours to few days) it stops polling.
We have seen in the logs that the sftp adapter stops gettling list of files after some time.
Any clues why's this happening.
Is there someway to tell FTP Adapter to create a new connection every time it goes to poll the files AND some way to keep the activation agent keep working instead of dying out when something bad happens.(e.g. timeout or ftp server unavailability etc).
We are going to production in 2 weeks and have just discovered this issue. Pls help.
thanks

Hi ,
i think currently your FTP Connection factory will have the following connection pool
<connection-pooling use="none">
</connection-pooling>
replace the above with the following properteis
<connection-pooling use="private">
<property name="waitTimeout" value="300" />
<property name="scheme" value="dynamic" />
<property name="maxConnections" value="10" />
<property name="minConnections" value="0" />
</connection-pooling>

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.

SOA FTP Adapter stops working abruptly

Hi All,
I have a ftp service which provides XML file streams real-time on a remote machine. I connect to this FTP server using the SOA FTP adapter and process files by polling based on timestamp every 3 seconds.
The issues I face are
1) The ftp adapter stop working abruptly. Has anybody faced this issue, if yes how can this be resolved?
2) The XML files comes to FTP location at the rate 2 files per second. Ideally I want to procss this files real-time using FTP adapter. But the backlog build is causing issues. How do I fix it?
3) If there is any downtime in production how should the SOA FTP application be activated after restart.
Also, what are the other FTP adapter configuration required to optimize the SOA FTP application to meet my business purpose.

I am using SOA 11g Fusion Middleware. The error I am getting in the logs are as follows:
