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.

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...

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,

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

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

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

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 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

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:

Hi,
I got problem with Sender JDBC Adapter. in the normal condition it is working fine. no problem at all.
The problem coming after network connection problem within XI and database for about more than 24 hours. After the connection resume the Sender JDBC Adapter doesn't want to pickup the data.

The problem resolve after restart the whole XI system. is there any other way to solve the problem without restarting the whole xi server. Because i have tried to stop and start the communication channel but still doesn't work until restart the xi. server.
Please advise.
Thank you and Best Regards

7. Network-Level Connection Problems
Q: The TCP/IP connection to my database host is running over an unreliable network connection, i.e. the connection is sometimes interrupted. Consequently, I sporadically receive an SQLException regarding a closed connection in the system trace or audit log or the connection as well as the JDBC Adapter channel are hanging.
How can I work around this connectivity issue?
A: Enable the "Advanced Mode" for the respective JDBC Adapter channel and select the option "Disconnect from Database After Processing each Message".
Note that this might put additional load on your DBMS due to the creation of a new database connection for each message.
If you are connecting to an Oracle database, also refer to question #10 for an alternative solution.

Sender JDBC to Receiver RFC scenario

Hi All,
I have to configure an scenario of sender JDBC to receiver RFC wherein SAP PI will be pulling data from third party database (Oracle).
Since I am configuring such scenario of sender JDBC, I want help on every important key aspects/prerequisites of configuring sender JDBC adapter/channel. I want to understand about Database Connection, Processing Parameters, etc. details while configuring sender JDBC channel and their significance/relevance.
Also I need guidelines about the source data structure (message type or external definition) to be used/created in ESR.
How sender JDBC channel and receiver JDBC channel differs from each other?
Please guide me on this.
Thanks & Regards,
Amit Patil

Hi Amit,
First of all you should read the sap.help documentation:
Configuring the Sender JDBC Adapter - Advanced Adapter Engine - SAP Library
Configuring the Receiver JDBC Adapter - Advanced Adapter Engine - SAP Library
Later, you can read Rajs's blog to advance concepts and perfomance JDBC Receiver scenarios best practices part-1
Finally, search the other blogs and documents in the SCN.
How sender JDBC channel and receiver JDBC channel differs from each other?
JDBC sender always does a poll to a DB table (with join some tables) in wich table you will need a field checkbox to mark the registers read, and the the receiver JDBC you can do a typical SQL construction like SELECT, INSERT, DELETE, etc. Both cases need the JDBC DB driver installed (check the SAP notes for this, also you can find some examples in the SCN:http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/8000cffc-6b92-2d10-3493-f2ac1399242f?quicklink=index&… PI/XI: deploy a JMS/JDBC driver without JSPM? ).

Hi Amit,
A JDBC sender adapter has 2 essential fields,
1. SQL Statement
2. Update Statement
Your SQL statement will contain your SELECT statement and once your SQL statement is executed, UPDATE statement is executed. This is done so that records that have been selected by the SQL statement should not be selected again as the JDBC sender adapter will poll over the database for every poll interval.
If you want to SELECT something from your Database, then you will have to go for a JDBC sender adapter.
But, if you want to insert/update your Database, then you can go for a JDBC receiver adapter.
Multiple insertions are possible for a JDBC receiver, but multiple Selection queries (different select queries) are not possible for a single JDBC sender adapter.
Just check these links to understand how JDBC adapters work,
If you wanna do update/insert you will have to follow the
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm">Document Formats for the Receiver JDBC Adapter</a>

Namespace issue in Sender JDBC message

Hi All,
My scenario is pulling data from Oracle DB(3rd party) and pushing it to SAP ECC system. Here I am using the table metadata in the form of an External Definition.I am directly using this ED in my message mapping and service interface. I am able to test the mapping locally, when I run the scenario the target message type is generated but the main element node inside is automatically suppressed. The structure examples are given as below(been taken from message mapping test tab):
Source
<?xml version="1.0" encoding="UTF-8"?>
<ns0:TABLE_NAME.resultSet xmlns:ns0="urn:sap.com:jdbcAdapter">
 <row>
 <A/>
 <BV/>
 </row>
</ns0:TABLE_NAME.resultSet>
Target:
<?xml version="1.0" encoding="UTF-8"?>
<MT_Inbound>
 <Main_Node>
 <X/>
 <Y/>
 </Main_Node>
</MT_Inbound>
I guess the problem is with the namespace and prefix which is coming along with the table metadata(ns0). I tried removing it by XML AnonymizerBean module in my sender JDBC channel but this did not solve the purpose.
Request you all to help in solving this.
Thanks in Advance
Lalitkumar.

As you should have already noticed, the structure of sender JDBC adapter does not match the meta data.
The structure of the ED imported is :
TABLE_NAME.resultSet
 TABLE_NAME.resultSet
 row
 A
 BV
The structure getting generated after polling the JDBC adapter is as given below(structure from moni inbound payload):
<?xml version="1.0" encoding="utf-8" ?>
- <TABLE_NAME.resultSet>
- <row>
<A>20110206</A>
<BV>06:38:56</BV>
</row>
I am not able to make out the difference here. I am able to also see the namespace when i check the same in the message mapping test tab.
I am also a little lost now as abhishek is on a different track.
Please comment.

Sender JDBC Adapter issue.

Hi folks,
I would like to know how can I configure a sender JDBC channel without specify a poll interval? I know that I can specify this poll interval with a period of time that I want; it could be in seconds and even in mseconds. But, this can cause a lot of access to the Data Base SQL Server and consequently can cause network slowness.
I would like to know if there is any data base event that can trigger my jdbc sender adapter or any other workaround that can prevent many accesses to one Data Base.
Any ideas are appreciated.
Thanks in advance,
Ricardo.

Hi,
with XI SP19 you can schedule your jdbc adapter easily:

Calling Stored Procedure from Oracle DataBase using Sender JDBC (JDBC-JMS)

Hi All,
We have requirement to move the data from Database to Queue (Interface Flow: JDBC -> JMS).
Database is Oracle.
*Based on Event, data will be triggered into two tables: XX & YY. This event occurs twice daily.
Take one field: 'aa' in XX and compare it with the field: 'pp' in YY.
If both are equal, then
if the field: 'qq' in YY table equals to "Add" then take the data from the view table: 'Add_View'.
else if the field: 'qq' in YY table equals to "Modify" then take the data from the view table: 'Modify_View'.
Finally, We need to archive the selected data from the respective view table.*
From each table, data will come differently, means with different field names.
I thought of call Stored Procedure from Sender JDBC Adapter for the above requirement.
But I heard that, we cannot call stored procedure in Oracle through Sender JDBC as it returns Cursor instead of ResultSet.
Is there any way other than Stored Procedure?
How to handle Data Types as data is coming from two different tables?
Can we create one data type for two tables?
Is BPM required for this to collect data from two different tables?
Can somebody guide me on how to handle this?
Waiting eagerly for help which will be rewarded.
Thanks and Regards,
Jyothirmayi.

Hi Gopal,
Thank you for your reply.
>Is there any way other than Stored Procedure?
Can you try configuring sender adapter to poll the data in intervals. You can configure Automatic TIme planning (ATP) in the sender jdbc channel.
I need to select the data from different tables based on some conditions. Let me simplify that.
Suppose Table1 contains 'n' no of rows. For each row, I need to test two conditions where only one condition will be satisfied. If 1st condition is satisfied, then data needs to be taken from Table2 else data needs to be taken from Table3.
How can we meet this by configuring sender adapter with ATP?
================================================================================================
>How to handle Data Types as data is coming from two different tables?
If you use join query in the select statement field of the channel then whatever you need select fields will be returned. This might be fields of two tables. your datatype fields are combination of two diff table.
we need to take data only from one table at a time. It is not join of two tables.
================================================================================================
Thanks,
Jyothirmayi.

Error in Sender JDBC communication channel

Dear All,
We have an interface in which we are fetching data from SQL database through sender JDBC communication channel.
Last week SQL server was upgraded from 2000 to 2008 and the communication channel has stopped working and is giving the following error:
Database-level error reported by JDBC driver while executing statement 'SELECT * FROM mstemp_tbl WHERE Active='0''. The JDBC driver returned the following error message: 'java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 1 (""): Data type 0x38 is unknown.'. For details, contact your database server vendor.
Please let me know if any JDBC drivers are to be installed for SQL 2008 or how can we resolve this.
Thanks,
NJ

Hi,
You may need to update your JDBC driver to 1.2 or 2.0. Kindly see supportability matrix on this link (question #2):
