Sender JDBC Adapter : Urgent Question

Hi,
I am working on a Oracle - XI - R/3 scenario. This scenario is working fine currently. The question that I have is what if I more than 500,000 records existing in the oracle table, then how many records will be picked up by the adapter when it polls the Oracle table . Will it try to pick up all the records, or does it pick up records in small packages..Can I set up the package size somewhere ??
I havent found an option in the adapter as such, and do not have high volumes of data in the Oracle table yet, so havent been able to run tests myself.
Thanks a lot
Any help will be appreciated

Bhavesh, Tim, Sandro ..
Thanks for giving me ideas in getting my issue resolved. I think I have the solution finally. I controlled the data being selected using the
SQL Query Statement " select * from zbwxi where rownum < 5000 and readflag = 'U' " and in the
update sql statement I put " update zbwxi set READFLAG = 'P' where rownum < 5000 and readflag = 'U' .
ZBWXI was by Oracle table which has a field called readflag.
I have run a few tests and the results look good to me ..
Let me know if you need explanation on why this worked ..
thanks for all your help

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?

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>

Sender JDBC adapter can be Synchronous?

Hi,
can we use sender JDBC adapter as synchronous in JDBC-XI-RFC Scenario without BPM?
thank you
babu

thank you for your reply.
Agasthuri,
that link doesn't explain about sender JDBC,it explains about reciever JDBC adapter and more over using BPM,I have asked without BPM.
Chandra
do you know how can we achieve this?please stick to my question sender JDBC-xi-RFC without BPM.
thank you again.

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 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 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.
Communication Channel Log Showing (Without finish Processing).

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.

Variables or parameters in Sender JDBC Adapter.

Hi,
I have the following question:
Is there any way to use variables or parameters when specifying the WHERE clause of a SQL SELECT statement or when using a Store Procedure in a Sender JDBC Adapter? If so, can anyone give an example.
Thanks in advance.

Configuring sender jdbc adapter

Hi all,
I have a requirement in which i have to select certain data from Oracle table and send it to an IDOC via SAP XI.
Problem is the select can happen from several tables. For example:
SELECT col1,col2,col3 FROM <tablename>
The <tablename> has to be variable. I do not need to do any JOIN. At a time select will be only from a single table i.e. col1, col2, col3 will all belong to the same table. But the adapter should poll multiple tables.
One more requirement is that once a particular record from a particular table has been selected some UPDATE also need to be done on the same record.
Pls can anybody provide me with a proper solution.
This requirement is a bit urgent.
Thanks in advance.
Regards
Neetu

Neetu,
You need to have the Table name dynamic in the Sender JDBC adapter's Select Query . This is not possible
You can consider using a Reciver JDBC adapter for which you can have a look at this blog ,
/people/bhavesh.kantilal/blog/2006/07/03/jdbc-receiver-adapter--synchronous-select-150-step-by-step
Or, you need a Separate sender JDBC adapter for every table to be polled.
>><i>One more requirement is that once a particular record from a particular table has been selected some UPDATE also need to be done on the same record.</i>
If you are using the Sender JDBC adapter, this would be simple using the UPDATE field of the Sender JDBC adapter .
If you are planning to use Receiver JDBC adapter, then You need a separate Send Step for this Update.
Better way to go would be to have separate sender JDBC adapters.

Error while executing the stored procedure through sender JDBC adapter

Hi All,
I am getting below error while executing the stored procedure through sender JDBC adapter.
Database-level error reported by JDBC driver while executing statement 'exec SapgetNextEntity 'SalesOrder''. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor.
what is the problem? any idea to anyone...

hi Dharamveer,
I am not getting below statement for your reply
Try to use Refrence Cursor it will return u reference of resultset.
I mention SP like this

Dynamic query configuration in sender jdbc adapter

Hi,
According my undertsnading in XI.3.0 dynamic query in sender JDBC adapter is not possible.
could any one confirms the possibility of this feature in XI 7.0 .
Thanks,
venu

Hi VJ,
sorry for late responding to your answer.
One of our requirements is the query statement that we write in sender communication channel should be changed dynamically, for example in where condition the condition parameters values required to change.
Thanks,

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.

the way i called SP is correct ??
please suggest me how to resolve the issue ??

We get "uFF06uFF03x0;" from sender JDBC adapter

Thank you.
This is naoki kurihara.
We have a problem in sender JDBC adapter.
We use java mapping and sender JDBC adapter in PI7.1 on Windows.(DB is sqlserver)
and we test the interface and we found error.
the reason is to get "＆＃x0;" from JDBC adapter.
and our java mapping can't parse it. and we got error.
the column is not null.
how we can prevent "＆＃x0;",
(sorry I cant write "＆＃" 1byte word, so I wrote 2bytes word)
please give me your help!!
Thanks

Hi,
Replace the & character with &amp ; in your java mapping. The same goes for these special characters:
< with &lt ;
> with &gt ;
" with &quot ;
' with &apos ;
Please remove the space between the escape character and the ; in your Java mapping. The spaces are typed here because the equivalent characters are not displaying correctly.
It should be able to handle the # though. Hope this helps
Regards,
Mark
