JDBC Adapter throws error for Null Data

Hi All,
I am running a interface Proxy to JDBC. But in case if proxy has no new data, the message which goes to the database is:
<b> <?xml version="1.0" encoding="utf-8" ?>
- <ns1:MT_Material xmlns:ns1="urn:sce-com:xi:fi:UnitEstimateData">
- <Insert_Material>
- <dbTableName action="INSERT">
<table>SCEI_UE_MATERIALS</table>
</dbTableName>
</Insert_Material>
</ns1:MT_Material></b>
and I get the error in RWB as <b>Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'SCEI_UE_MATERIALS' (structure 'Insert_Material'): java.sql.SQLException: FATAL ERROR document format in structure 'Insert_Material': expected 'access' tag(s) not found</b>.
Is there a way so that the JDBC adapter doesn't throw any error if there is no access node??
Pls advice...
XIer

Xier,
Why it will create multiple Insert_Material nodes? Use like this
Mandatory segment ->Remove context->Collapse Context ---> Exists -
>insert_material.
Try the above and let me know if it doesn't helps!!

JDBC: Database-level error

Hi Folks,
I'm trying a JDBC to JDBC scenario and I'm getting the following error.
*Database-level error reported by JDBC driver while executing statement 'select * from EMPLOYEE where flag = 'X'.'. The JDBC driver returned the following error message: 'java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'flag = 'X'.'.'. For details, contact your database server vendor.*
My select statement is : select * from employee where flag = 'X'.

Jdbc adapter: DeliveryException error

Hello
I have the following synchronous scenario: RFC <-> JDBC Adapter.
The RFC is executed many times in a job and 99% of them works well, but some of them I receive the error:
Returning synchronous error notification to calling application: com.sap.aii.af.ra.ms.api.DeliveryException: XIAdapterFramework:GENERAL:com.sap.aii.af.ra.ms.api.DeliveryException.
Can anyone help me ?
Thanks
Vitor Zaninotto

You are getting error whenever there is a connection refresh between SAP R/3 and XI. you can resolve it by following way.
Actually the RFC sender channel will try to reconnect to the SAP Gateway. If this reconnect fails, the next reconnect attempt is made after a waiting period of 1 second. If the next reconnect fails also, the waiting period is doubled and so on. This will lead to a reconnect timing of 1, 2, 4, 8, ..., 3600 seconds. Saving recources is the aim of this technique.
Once the maximum time is reached, the RFC channel does not stop connecting. It continues to try connecting indefinitely. The waiting period is a constant interval of the maximum time that is set, i.e. after every 3600ms.
If not configured, the maximum waiting time is defined in the middleware layer of SAP JCO, which is 3600 seconds. But this maximum time can be configured for each RFC sender channel in the XI Integration Directory. Open the Advanced Mode for the RFC Server Parameter.
Before SP 12: Add a line to the table and use 'jco.server.max_startup_delay' as name and the maximum number of seconds to wait between reconnect attempts as value.
Since SP 12: Enter the maximum number of seconds to wait between reconnect attempts in the field Maximum Reconnect Delay.

Adapter Level Error To be Delivered

Hi Guys,
i got few messages status with status as " To be Delivered" in Receiver Adapter level.
i tried to resend the message from Runtime work bench, its not working.
generally i got this type of status at target adapter level. everytime i did resend the messgaes from runtime workbench it self.but this time its not working fine.
i checked adapter status as well, everything looks good.
can any one pls expalin me how to resolve this issue.
Regards,
Siva.

Hi,
This can be due to the EOIO QOS for the messages...
Check the messaging system http://host:port/MessagingSystem/ ...here you can see the tab EOIO Sequence monitor...
There you should be able to find the message which failed and as a result another message went into Waiting state..
Once you clear off those messagess ...Message from ToBeDelivered state will be changed..

JDBC Adapter delivering error

Dear All,
When we send messages using JDBC, if any of them with error data and could not be executed successfully, the one appears in the status of 'delivering' for a long time, and all the following messages to be sent using JDBC will be blocked in the same status too, even if the connections are to the different target database. We shall always see the phenomena in RTW, until messages are in the system error for a very long time. We have set the retrying papameter with 1 in JDBC channel. Any answer will be appreciated.
Regards,
JM Z.

james,
Any messge that has an error in the adapter engine will be restarted / retired 3 times at an interval of 5 minutes. In your case I guess you do not want the restart . To change this parameter , take a look at this blog,
/people/sap.user72/blog/2005/11/29/xi-how-to-re-process-failed-xi-messages-automatically
<i>We can achieve this by changing the retry count used by the Adapter Engine, by default its set to 3 times, 5 minutes apart. This count can be changed in Visual Admin->server->services-> SAP XI Adapter: XI.
Here change the number Retries parameter from 3 to 10 and change the retry retryInterval to around 10minutes. For these configuration changes to be picked up, restart SAP XI Adapter: XI.</i>
Is this what you are looking for?

JDBC Adapter - Sender - Stored Procedure - SQLException Error

Hi,
     I have created one stored procedure in our Oracle database. I give below that stored procedure.
CREATE OR REPLACE PROCEDURE sp_stud
IS
    l_row student%ROWTYPE;
    TYPE t_ref_cursor IS REF CURSOR RETURN l_row%TYPE;
    c_cursor t_ref_cursor;
BEGIN
    OPEN c_cursor FOR
     SELECT *
     FROM student where readflag= ' ';
    LOOP
     FETCH c_cursor into l_row;
        EXIT WHEN c_cursor%NOTFOUND;
        DBMS_OUTPUT.PUT_LINE(l_row.id || ' : ' || l_row.name);
    END LOOP;
close c_cursor;
END;
This is a procedure to retreive rows from the table student which is having the field read_flag = ' '; (Student table contains the fields ID, NAME, BIRTHYEAR, BIRTHMONTH, READFLAG).
In JDBC Sender Adapter, I set the values for the following fields under Parameters tab.
Query SQL Statement: EXECUTE sp_stud
Update SQL Statement: UPDATE student SET readflag = 'Y' where readflag = ' '
The scenario is every 5 minutes JDBC adapter checks the table whether any new row is inserted, if it is inserted and commit, it will send that record to File. This is the Scenario.
In Runtime Workbench, Communication Channel Monitoring, it shows the following error, when JDBC Polls the table.
Database-level error reported by JDBC driver while executing statement 'EXECUTE sp_stud'. The JDBC driver returned the following error message: 'java.sql.SQLException: ORA-00900: invalid SQL statement '. For details, contact your database server vendor.
Note : If we execute the Stored Procedure ad SQL command level, it works fine.
Kindly help friends to solve this, where the error is happened.
Thanking you,
Kind regards,
Jegatheeswaran P.

Hi,
Not a Database expert. But , in case you have not seen the note pointed by Deepu,
<i> The JDK 1.1.x, 1.2 and 1.3 versions (classes111. zip, classes12.zip, classes12.jar) of the driver are not compatible with the SAP XI JDBC Adapter. Use the JDK 1.4 driver (ojdbc14.jar) instead. For details, refer to Oracle MetaLink note # 203849.1.
           <b>Invoking Oracle stored procedures from within a JDBC sender channel is only possible for Oracle DBMS versions >= 10.2.x using so-called table functions:</b>

FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED;

Handling JDBC adapter errors in BPM

Hi,
I am using BPM to insert data in SQL server using a snychronous send.However i am not able to trap the adapter errors like server is down or could not insert because of key violation.
Hence i decided to use transport level ack. But i understand that error description is returned in fault messages. Can i use fault messages in BPM???
And also if that is not possible, I would like to know how can i configure alerts in JDBC adapter.
Thanks in advance.

Anand,
I dont think this is possible. Fault Messages should be sent by the Application System back to XI , the Database in our case. AFAIK< the database cannot send back such fault messages and the error message is trapped in the JDBC adapters log. Try using Adapter Engine Alerts and this will cause the Message to be passed to your ALert framework from the adapter.

Bhavesh

Database-level error reported by JDBC driver

Hi everyone,
I get an error in my Sender JDBC adapter. I am executing a stored procedure every minute. In total I have 34 JDBC senders for every different database. The error is like below. The problem is in Alert Inbox I cant see the rest of the message. This error occures just once every hour (average). I dont know why and I dont know what the rest of the error is saying.
Any ideas how i can see the rest of the message? And where the error might be?
Note: In communication channel monitoring everything is green.
Database-level error reported by JDBC driver while executing statement 'EXEC [TB

Hi,
obviously there are concurring accesses to the table your stored procedure is accessing. This is nothing serious, because SAP XI will retry the execution of the stored procedure according to the settings of the communication channels (3times all 5 minutes is the default). Additionally you can set the repeats in case of SQL errors in the extended tab of the communication channel configuration.
Tuning the transaction isolation levels might help to avoid the error but can decrease the consistency of the data as well. Default isolation level is always the highest available in a database (in case of SQL Server it should be SERIALIZABLE), so locks might easily occur. I would suggest to have a look at other applications accessing the tables and determine their isolation level.
All in all, I guess there shouldn't be real problems, because of the repeated execution of you stored procedure, but it's worth to have a look at the isolation level.

Error when calling JDBC Adapter parallel

Hello,
we have several interfaces which consume data from an AS400 machine via JDBC Adapter.
Interfaces were running for several months without any problem. Now we get the following error message when few interfaces try to deliver data at the same time:
com.sap.aii.af.ra.ms.api.DeliveryException: Channel has reached maximum concurrency (5,000 concurrent messages) and no free resource found within 5,000 milliseconds; increase the maximum concurrency level
Unfortunatly we didn't find any hints what could cause the appearence of this Error.
Can anyone help me?
Thanks
Carsten

Hi,
By default Maximum Concurrency = 1 in communication channel. Which will open one connection with the Database. Since your data volume and call is large so if you define it more then 1 then it will open multiple connection for you and your transaction rate will be faster.
1. Maximum Concurrency = 1
This is the default value of Maximum Concurrency. This means a single receiver JDBC channel can acquire only one DB connection.
This case does not offer any parallel processing of messaging by single channel.
2. Maximum Concurrency > 1
This ensures that resource pool size(DB conneciton size) is limited to specified value per single JDBC receiver channel. For instance, setting this parameter to 2 will ensure that a single receiver JDBC channel can acquire 2 DB connections in parallel(if needed).
And also:
if You are Using PI 7.0 SP 12, You can set the maximum concurrency level for Receiver File & JDBC Adapter.
By Default Maximum Concurrency level=1.
Procedure to change:
Go to Receiver Comm Chann of File/JDBC adapter.
Goto Processing Parameters and then check Max Concurrency level
Plz do refer the following docs:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/4042611d-04e5-2910-bd9d-f97627b1c164
