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:

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.
Regards
Amit

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.

Error in calling stored procedure in sender JDBC adapter

Hi Experts,
I am working on MySQl to SAP scenario. I have to use stored procedure in sender JDBC adapter.
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'. For details, contact your database server vendor.
the way i called SP is correct ??
please suggest me how to resolve the issue ??

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.

Sender JDBC adapter slow processing in Production

Hi All,
We are facing an issue with processing time for Sender JDBC adapter.
We tested a scenario in Quality for JDBC to Proxy. In quality the Sender JDBC adapter is taking around 30-50 sec. to send data to PI, but in production the JDBC adapter is taking more then 7 mins to send the same amount of data from DB to PI.
We have checked the setting in PI; it is same in both the systems (Q and P).
Even the parameters for both the servers maintained same.
Can any body please suggest the reason of this behavior and any workaround?
Regards,
Rahul

Based on my experience, these are the things that could be used to improve JDBC performance
1. You may increase the thread count for JDBC related queues. This has to be done in accordance with SAP Note 1084161.
2. There is parameter in JDBC communication channel called Maximum Concurrency. It signifies that one communication channel can make how many connections to database. This is 1 by default and could be increased to some values like 3-4.
3. In the Visual Admin/ NWA, there is a parameter called as queueParallelism.maxReceivers which defines the number of parallel worker threads for one receiver channel instance. This should be done following SAP Note 1136790. This can be done along with the first point.

Executing an Oracle Stored Procedure from Sender JDBC adapter

I could really use some help from someone who had done this before.
I've read the help about using the JDBC sender adapter, but it's not helping enough.
I found this line: "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."
That's definately what we want to do, but we can't figure out the syntax.
The procedure in oracle looks like this:
CREATE OR REPLACE PROCEDURE test_ref_cursor
( cur_generic IN OUT result_sets.cur_generic)
as
BEGIN
Open cur_generic for
select
   proposal_number,
   to_char(sequence_number),
   column_name,
   column_value,
   update_timestamp,
   update_user
   from
   coeus.sap_test;
END test_ref_cursor;
And we have tried every kind of statement we can think of, but the file adapter always gives us an "invalid sql statement" error.
Does anyone know what syntax we need to put in the "Query SQL Statement" in the JDBC sender adapter in order to call this procedure? Or is there something wrong with the procedure that is causing the error?
<i>I will absolutely return and give points, but PLEASE read my whole post before answering and do not just link me to or quote the help for configuring a sender JDBC adapter or blogs that are about the JDBC adapter in general but do not deal with the issues I am having. Thank you.</i>

Hi Vanda,
Unfortunately, the sender JDBC adapter does not support Oracle's store procedure/function. Unlike stored procedures from other database vendors, Oracle returns a cursor, not a resultset. The sender JDBC adapter must send a resultset to XI.
There are 2 possible ways you can accomplish this:
1. Use BPM and call the Oracle stored procedure using a receiver adapter via a asynch-synch bridge.
2. Develop a user-module for the adapter, which can be used with a sender adapter.
Thanks

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>

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...

Ramesh

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.

Nutan

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
