Sender JDBC adapter: duplicate data sent

Hi experts,
The scenerio is XI is polling the Data from source system using JDBC sender adapter. But the duplicate data is being sent to target system. I have check the chaneel configuaration and it is as follows:
Polling Intervals(secs) = 3600
and schedulling for the channel in RWB is set as: Daily at ......AM for 2 hours
as per my understanding the here the adpater is polling the data for one hour and again it starts polling for another one hour which is set in secheduling.
If I set the Availability planing as Daily at ......AM for 1 hour then problem can be resolved.
Please advise.
thanks,
Regards,
Mohan

This could be resolved if you can add a field in the DB table like 'ReadFlag'.And your sql statement should have a check on this field.
You can ask someone(who can actually make changes in the Database) to add the field in the Table.

Sender JDBC Adapter - Stored procedure

Hello all, I just read a lot of topics in this forum about this subject.
I found two indications in contracdictions in the documentation :<a href="http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/frameset.htm">Configuring the Sender JDBC Adapter</a>
1. Concerning Query SQL Statement
You have the following options:
● Specify a valid SQL SELECT statement to select the data to be sent from the specified database.
● Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
2. Concerning Update SQL Statement :
This is recommended if the data has not only been read, but also changed by a stored procedure entered under Query SQL Statement.
It is ambigous, isn't it ?
My question is simple :
Does somebody already use Sender JDBC Adapter with Stored procedure as Select statement including many steps :
- update actions on database
- select query to return data to XI adapter
(Update statement stay empty or with value <TEST>.
To provide more information, I have a reference table to read. But this reference table must be updated by a stored procedure before being able to be read accordingly.
So As I can't do both process with Sender Adapter (call a procedure and execute a select statement) => I want to include both actions (updates and select) in an alone stored procedure.
Could I get wanted data as a resultset ?

Hi,
>><i>Update statement stay empty or with value <TEST>.</i>
It should be <TEST> if you do not want an Update to happen.
Regarding Sender JDBC adapter with stored procedures, which DB are you trying to access. Sender JDBC adapter does not support Oracle Stored Procedures as they return Cursors and Sender JDBC adapter can deal with only Resultset.
As for executing both Update and Select in the SP, though I havent tried, this should surely be possible.

Sender JDBC adapter : Update SQL Statement : stored procedure

Hi,
Can we use a stored procedure in the sender jdbc adapter in 'Update SQL Statement'.
The problem i am facing is like, we are selecting data from two tables in 'SQL statement for query' and then in 'Update SQL Statement' , we need to delete that data from these two tables.
Please let me know if it is possible.
Thanks,
Rohit

you can use a Stored procedure in the
Query SQL Statement
You have the following options:
· Specify a valid SQL SELECT statement to select the data to be sent from the specified database.
· Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
The expression must correspond to the SQL variant supported by the relevant JDBC driver. It can also contain table JOINs.
so have your whole select and update as part of this single Stored procedure

Sender JDBC adapter donot want to update database..

Hi,
We have JDBC to RFC scenario. In This we need to read only database table , we should not update it. As in sender JDBC adapter configuration Update SQL Statement is mandatory, so what needs to be done in this case?

Hi,
In place of the SQL statement, you can also enter <TEST>. Once the data determined from Query SQL Statement has been successfully sent, the data in the database remains unaltered.
This is recommended if the data has not only been read, but also changed by a stored procedure entered under Query SQL Statement.

Sender JDBC Adapter in a synchronous szenario

Hi,
i am trying to set up following szenario:
A JDBC Sender Adapter is polling data from a database, this data is beeing mapped to a synchronous RFC-Call to the R/3 backend. The result from the RFC-Call contains an order-number, which should be stored in the database.
The query of the DB and the rfc-call works fine. The query is also doing the UPDATE statement to the DB, marking this line of data as beeing processed.
The QOS in the sender-jdbc-adapter is set to "Best Effort", which should allow a synchronous communication.
I am mapping the response of the rfc-call to a jdbc-receiver-like structure, in the monitoring i can see the rfc-result and also the message to update the databae. There are no errors in the adapter-monitoring and everything looks fine, except that the database is not beeing updated.
Is there another messageformat for the synchronous answer to a sender-jdbc-adapter? Or is it possible, that the commit for the answer is not beeing sent?
We have an XI3.0 with SP16 installed.
Thanks for your help.
Ingo

hi,
you cannot use the Sender JDBC adapter to Upate.
Create a receibver JDBC adapter with the format as mentioned and use it to update the DB.
the steps in BPM wil be ,
1. Receive -- for Sender JDBC adapter
2- Send Synchronous -- RFC call synchrnous
3 - Send -- using Receievr JDBC adapter to Insert / Update the DB.
Do let me know if u need further info,

Questions about sender JDBC adapter

Normally we use sender jdbc adapter in this way:
query statement:
SELECT * FROM table WHERE processed = 0
update statement:
UPDATE table SET processed = 1 WHERE processed = 0;
The update statement will be executed after the message has been successfully sent to XI.
My questions is that what will happen in this scenario:
A new record (processed=0) is added to the database table when a message is sent to XI with query statement but not finished?
After the message is sent to XI successfully, XI will execute the update statement. Then the new added reocrd will also be updated to 1 although it hasn't been sent to XI.
Does XI have some control or special check for this issue?
Regards
Hui

Hi,
this can be handled by the ISOLATION LEVEL FOR TRANSACTION setting of the sender Jdbc adapter.
make the transaction handling to SERIALIZABLE or REPEATABLE READ and then until the data is not read from the JDBC adapter and it is not updated by the UPDATE statement , no new rows will be allowed to be inserted into the database. The database will be write locked.
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
<i>Isolation Level for Transaction
There are different levels of database transactions known as isolation levels. The isolation level determines how transactions running in parallel influence each other. The options correspond to the JDBC constants:
   Default (default setting of the respective database)
     None
    read_uncommitted (weakest setting)
    read_committed
     repeatable_read
     serializable (strongest setting)</i>

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.

I am calling SP as fallows: execute proc_dtdc_booking_interface_sd
But it returned following error,
Database-level error reported by JDBC driver while executing statement 'execute proc_dtdc_booking_interface_sd'. The JDBC driver returned the following error message: 'java.sql.SQLException: Unknown prepared statement handler (proc_dtdc_booking_interface_sd) given to EXECUTE'.

Sender JDBC Adapter and Synchronous Interfaces

Hello
I have a Oracle/JDBC -> XI -> ECC/RFC scenario. The communication mode is Synchronous.
In the Oracle database I have a table with a "STATUS" field. When JDBC Adapter Sends the rows from this table to the Integration Engine, it updates the "STATUS" from "G" (GENERATED) to "R" (READ).
The response from the RFC contains for each row sent to RFC a "STATUS_from_RFC" field, that I would like to use to update Oracle STATUS field to "S" (SUCCESS) or "E" (ERROR).
Can the Sender JDBC Adapter use the response from the Synchronous RFC to update Oracle "STATUS" field itself ?
Or do I need a Receiver JDBC Adapter? In this case, I have to use asynchronous communication and BPM, ok ?
thanks
Julio

Bhavesh,
<i>>>>But, the online help states it supports QOS of BE and so it does support Synchronous Processing.</i>
Even File adapter has QOS of BE
To my understanding response back is possible only if it is PUSH + Sync
Adapters PUSH + Sync
HTTP
SOAP
RFC
XI
etc...
For the above response is possible
Adapter PULL + Sync
File
JDBC
etc..
In general there can be a response if there is a request. In the case of File and JDBC there is no request message coming to the adapter, its the adapter which is actually requesting.
This is just an idea and my understanding.. might not be true If possible do try it and let everyone know I will also give it a try when time permits
Thanks,
Prakash

Sender JDBC adapter...problem

Hi,
the real problem is Sender JDBC adapter sends data in following format.
<?xml version="1.0" encoding="UTF-8"?>
<resultset>
<row>
     <Associate_ID>16444</Associate_ID>
     <Associate_Name>Sudhir</Associate_Name>
     <Status>false</Status>
</row>
</resultset>
But in Design time mapping...structure of source message will be like
<?xml version="1.0" encoding="UTF-8"?>
<ns5:DB2File_DB_MT xmlns:ns5="urn:db2file">
<Resultset>
    <Row>
      <Associate_ID>16444</Associate_ID>
      <Associate_Name>Sudhir</Associate_Name>
      <Status>false</Status>
    </Row>
</Resultset>
</ns5:DB2File_DB_MT>
How does this tag ... <ns5:DB2File_DB_MT xmlns:ns5="urn:db2file"> get generated in runtime
and apart from 1 to 1 mappings b/w the three fields above in the row tag...wt other mappings to be performed
Pls help...
Sunita

Hi Sunita,
what i understood from your query is namespace tag is coming while message mapping. This namespace can be avoided in the message type if you keep the XML namespace field empty while creating message type. But i afraid you have to do the message mapping again.

Sender JDBC Adapter Supports Stored Procedures????

Dear All,
I was trying to use the Sender JDBC adapter to call the Stored procedure in the Sender JDBC adapter is possible to do this???
I don't think Sender JDBC Adapter is supported to execute the Oracle Started Procedures. With my understanding only the Receiver JDBC Adapter will supported for the Stored Procedures using the message mapping Action = EXECUTE and Table = DBO.EmployeeMasterTable.
Please let me know how to achieve the below scenario.
My Scenario JDBC to RFC
Query SQL Statement:
select * from dbo.emp where flag = 'Insert' or flag = 'Update' or flag = 'Delete'
Update SQL Statement:
UPDATE dbo.emp SET flag = null WHERE flag IN ('Insert', 'Update');
DELETE dbo.emp WHERE flag = 'Delete';
In the my update statement I need to update few data flag with Insert , Update and need to delete the of the old records as mentioned above the query.
In the response mapping I am using the Action = INSERT and Table = emp.
Thanks,
Jane F.

Hi Jane,
>>My requirment is to select from the DB and update and delete needs to be done. How I need to call this stored procedure in Sender JDBC adapter.
An example of SP call is mentioned in the previous note Note 941317 - XI / PI JDBC Adapter: Known Problems / Incompatibilities
SP Code
          ---------- pkg1 ----------
CREATE PACKAGE pkg1 AS
TYPE numset_t IS TABLE OF NUMBER;
FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED;
END pkg1;
CREATE PACKAGE BODY pkg1 AS
-- FUNCTION f1 returns a collection of elements (1,2,3,... x)
FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED IS
BEGIN
    FOR i IN 1..x LOOP
      PIPE ROW(i);
    END LOOP;
    RETURN;
END;
END pkg1;
In sender channel mention
>> SELECT * FROM TABLE(pkg1.f1(5));
>>Is this need to be in the one stored procedure right. Can ou let me know how it should be handled in JDBC Adapter.
Yes it shoudl be a single SP. Mention a select statement as given in above example.
What is your Oracle version?

Sender JDBC Adapter Select/Update Issue

Dear All,
We have configured a Sender JDBC Adapter to Poll data from the DB2 tables. It is working fine and both the select and the update queries written are also getting properly executed and are changing the status of the flag from Y to N once read from database.
In the communication channel ->
select * from <table> where flag = 'N'.
update <table> set flag = 'Y' where flag = 'N'.
But I have one doubt after executing the select query some new data comes into the table of status flag 'N"., then will this unselected data will also be updated to 'Y' .
The question is while we do a select and update from XI on the DB table and at the same time there is an insert happening into the table from the other end how will the adpater behave in this case.Will it result in missing of some records during next select/update transaction from XI..
Your inputs will be appreciated.

Sender JDBC Adapter hang after network problem ?

Hi,
I got problem with Sender JDBC Adapter. in the normal condition it is working fine. no problem at all.

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

Check JDBC FAQ note 831162
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 adapter SELECT / UPDATE issue - updates more rows than selected

Hi,
We have configured a Sender JDBC Adapter to poll records from an Oracle table based on a flag field and then update the flag for the selected records. When tested in DEV and QA environments (where test data comes in intermittently and not in huge volumes), itu2019s working fine.
Both SELECT and UPDATE queries written in the Sender JDBC adapter are getting properly executed and are changing the status of the flag for the selected records from Y to N once read from the database.
select * from <table> where flag = 'N'.
update <table> set flag = 'Y' where flag = 'N'.
But in the PROD environment (with records getting updated in the database every second), after XI executes the SELECT query and just before the UPDATE query is executed, new records come into the Oracle table with status flag 'N". So when the UPDATE query runs just after the SELECT query, then these unselected records also get updated to 'Y'. Thus these records never get into the resultset and hence XI and thus remain unprocessed.
So when XI does a SELECT and UPDATE on the Oracle DB table and concurrently there is an INSERT happening into the table from the other end, the JDBC sender adapter is picking up a certain number of records but updating the status of more records than it picked up.
So how does XI deal with such a common scenario without dropping records?
Thanks,
Vishak

The condition being checked is the same for both SELECT and UPDATE statements.
Initially I tried setting transaction isolation levels on the database to repeatable_read and serializable but it was throwing me a java.sql.SQLException error saying that these transaction levels were not valid.
I asked for these transaction level permissions for the XI user from my DBA but the DB I am accessing provides only a view into other databases and so it's not possible.
