Errrror in sender JDBC channel in rwb

hi forum,
in a JDBC to XI scenario,
the sender JDBC channel, in rwb, shows error:
Status: RED
Short Log: Adapter has not provided any information for this channel
Error information: Exception: Channel with status unknown or Not Registered
pls help, its in production system

RAJ,
these channels were always active an working fine,
let me explain the problem in detail,
we have three cluster nodes for XI system,
so, in rwb, communiation channel monitoring, we can see the status of a channel corresponding to the 3 nodes seperately,
here i can see that, for 2 nodes the channel is GREEN and working, but for one of the node, it gave the already mention error

Retreiving data from 2 tables using a sender JDBC Channel

Hi all,
We got anew requirement where we have to select data from 2 tables and update fields in 2 tables at the sametime.
I have a few queries regarding this.
Can we retrieve data from 2 tables using select query in sender JDBC channel?
If yes, how we can achieve this?
Can we use inner/outer joins in the select query?
Can we update field of 2 tables using the Update query in Sender JDBC channel?
Your help is greatly rewarded.
With Regards
Sudha.

Hi,
Even i have the same requirement where data has to be read from 2 tables and later update the falg once done .
SELECT query :
SELECT t1.KUNNR,t1.SETT_KEY,t1.QUART_START,t1.QUART_END,t2.PAY_METH,t2.MAT_NDC,t2.AMOUNT FROM TSAP_REBATE_MEDI t1 INNER JOIN TSAP_REBATE_LINE t2 ON t1.KUNNR=t2.KUNNR AND t1.SETT_KEY=t2.SETT_KEY WHERE t1.PROCESSING_STATUS = 'N' AND t2.PROCESSING_STATUS = 'N'
This is working fine.
Can somebody help me with update query with this. where flag PROCESSING_STATUS has to be updated with 'P'.
I tried a lot but couldnt get the answer

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

Dynamic select querry in sender JDBC channel

Hi,
We are working on a scenario where we need to read data from various database tables , we were trying to see if it is possible that the select querry can be set dynamically so that the same channel can be used to read from the various tables.
Request all to please come up with suggestions as to whether this is possible.
Thanks ,
Pravesh Puria.

Hi All,
Thanks VJ for your reply.
Let me reframe my question.
I have multiple database instances at source side. On all instances I have same table name.
My requirement is to poll all these instances table and fetch data.
Do I need to create multiple sender agreements or there is a way to dynamically change the datbase name in sender Communication channel.
Any other solution is also appreciated.
Same is the case with JMS adapter, Multiple instances of JMS are there at source side sending similar structure data in there own queue.
Request you to kindly response.

Stored procedure in Sender JDBC Adapter

Hi All,
My Scenrio goes like this ...
Stored Procedure(SQL Server) --- PI -
File
I need to write the results of stored procedure to File.Here I don't need any mapping.So how many DT , MT and MI need to be created?
The interface need to run by 6AM from Monday to Thrusday, how can i achieve this ?
Stored Procedure has only select statement and no Update statement , but it takes Date as Input parameter , so what i need to provide in sender JDBC adapter.
Thanks,
Monish

Hi Monish,
As per your requirement it is JDBC to File. Please be careful with the structure to be created for sender JDBC. I am unable to understand why you donot require a mapping for this. How XI will send the data to a file then.As per my knowledge if it's file to file and just pick and drop then we can neglect IR and go for ID.But here you are working with JDBC and File so you will be in need of it.
IR:
DT: 2
JDBC_Sender_DT
File_Output_DT(Optional)
You can use the JDBC sender data type structure for File output also.
MT as per your DT
MI:2
Outbound MI: JDBC structure
Inbound MI : File structure
MM: 1
IM: 1
ID as similar to other scenarios.All 1 objects for RD,ID,Sender Agreement and Receiver Agreement.
Sender JDBC channel:
Query: Select * from table where date
But I have a query how are you providing date in input paramerter.It will be dynamically entered into the query right.
You can mention the Avalibility planning for your interface to work in RWB.
Go to RWB>Component Monitoring>Adapter Engine->Communication Channel Monitoring>Avaliablity Planning
Please explain.

Broken pipe error in Sync Send JDBC Receiver: Extremely Serious issue

Hi forum,
I have a serious error in a JDBC->XI--> JDBC scenario,
Step1: I use a sender JDBC channel to select some distinct values from a table say X, and update the same rows,
Query SQL Statement: select distinct Branch from dbo.X where status = 0
Update SQL statement: update dbo.X set Status = 2 where Status = 0
Step 2: enter BPM
Step 3: enter a loop
Step 4:make a synchronous call to the same table X, to fetch some records,
SQL query: select * from X where status = 0 and Branch = i; Update X set status = 9 where Branch = i
Step 5: close loop, this loop iterates for 5 or 6 times depending on i, which is no. of branches selected by the sender JDBC channel
so all the calls are to the same table, same databsse(SQL Server)
the problem is when this sync calls happens in the loop, it some times gives following error, which i se in RWB:
<b>Error Unable to execute statement for table or stored procedure. 'X' (Structure 'STATEMENT_X') due to com.microsoft.sqlserver.jdbc.SQLServerException: An exception occurred during the DBComms.transmit operation. Exception:Broken pipe (errno:32). Context:(2217)</b>
i have no way to trace the cause of the error, the database is perfect and the error logs in the SQL server shows no trace of any error,
Note: It works sometimes
i dont know whom to approach, pls help
the issue is very very serious as its in production system,

Hi Sudeep,
SAP Note 846079 - XI 3.0 JDBC Receiver: # of Retries on SQL Error w/o Effect
Please check the following SAP note also - 831162
Some info which i found there and can be relevant in to your scenario.....
Q: I am using a JDBC Receiver Adapter in conjunction with the Lotus Domino Driver for JDBC perform an INSERT or UPDATE operation on a database. When sending a message to the receiver, the Adapter Monitoring shows the following error message:
"java.sql.SQLException: [Lotus][Domino Driver for JDBC]Invalid cursor state"
Is there a fix for this issue?
A: To work around this JDBC driver problem, activate the Advanced Mode for the respective JDBC Receiver channel and configure the setting "Number of Retries of Database Transaction on SQL Error" to a value > 0. Additionally, make sure that the setting "Database Auto-Commit Enabled" is also active as the Lotus Domino Driver for JDBC does not support transactions.
Apply note 846079 before configuring this scenario.
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.
I dont have access to a database right now, so i am not able to check this.
Also check the JDBC driver compatability as mentioned in the above note.

Sender JDBC Communication Update SQL Command Problem!

Hi all,
I am trying to do a SENDER JDBC Scenario in XI.
I fetch the Records from the table Once per day based on the Current Date.
I do not have any Update Credentials in the table.
I can only perform Select Querry.
But when i am trying to configure the SENDER JDBC Channel its asking me to enter value for Update SQL Command in Sender JDBC communication channel Process Parameters.
Its not accepting BLANK or ' * ' Values.
But i have only Select Querry credentials in the table. I can only pick the values cant Update the tables but.
In the Above scenario how can i configure the Sender JDBC CC without Updating the Table after fetching the value?
Please Advice

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? ).

Problem with Sender JDBC adapter using StoredProcedures

Hi All,
I am facing some prblem when i am using StoredProcedure. Please look at the error which i observe in the traces when i try to execute a stored procedure using Sender JDBC channel.

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.

Sender Communication Channel going down

Hi Experts,
We are on XI 7.0 with patch level SP12. We are having one problem. when we are starting the Sender JDBC communicaton channel it is working fine for the first time. but the moment there is any change in the sender or Receiver RFC communication channel. may be due to wrong system ID etc. the Sender JDBC channel goes down. Actually it shows it is running but it does not poll / pick up any records.
pl. note that subsequent changes which we had done to either to Sender JDBC channel or Receiver RFC has been rectified & re-deployed.
This problem get solved if we create a New Sender JDBC Channel.(But i guess that should not be the soluation)
I have used the following Modules in Sender JDBC channel.
AF_Modules/RequestResponseBean
localejbs/CallSapAdapter
AF_Modules/ResponseOnewayBean
Pl. Help.....
Regards,
Umesh

Does it go down even if a message is processed succefully or just if there is some error with the configuration?

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.
