Duplicate data updating in Oracle DB by JDBC adapter

Hi ,
I am developed Idoc to JDBC senario. One sigments was coming N number of times. for example 30 time. In that 3 diffrent disribution channel data. but I want to send only 3 records for each distribution channel.
I connected that segment to access in JDBC structure to repaet the data, because of this all 30 records are going. I want to avoid duplicate records. Please help how to do it?
Thanks,
Venkat

Hi,
You can control this in mapping.
You can suppress the duplicate records in mapping.

NCHAR issue with oracle database using JDBC adapter

Hi,
We have a requirement to develop an XI interface from FTP server(File adapter) to oracle database using JDBC adapter. In the oracle database table few fields are of type NCHAR/NVARCHAR. when we try to insert the character(A,B,c..) values into oracle table fields of type NCHAR/NVARCHAR, we are getting the following error message in the JDBC adapter audit log. IF we pass the numeric value to the same field, then we are able to insert the records successfully.

Read data from 3 tables in sender JDBC Adapter

Hi All,
I doing a scenario JDBC to IDOC I need to read 3 tables of ORACLE. how JDBC sender adapter will retrieve data from more than 3 ORACLE tables and also i need to update control status fields of these tables.
Please provide me the syntax for the select and update.
Thanks in Advance
Regards,
Nisha

Hi,
Select Syntax:- select Table1.Field1, Table1.Field2, Table2.Field3, Tabl2.Field4
From Table1 , Table2 where Table1.Field1 = Table2.Field3.
Similary use this Syntax for three Tables.
Update Syntax: -
In SP Check if Data Seletion is suceesful then Use the seperate Update statement for each table.
like Update Table1 set Field5 = 'Value'
where Field1 = 'Value'.
Also use the refernce link provided by Mr.Vinithra Iyangar.
Thanks

Access an Oracle DB using JDBC adapter

Hi, I'm trying to make an simple test for checking if the connection between XI and Oracle DB is working fine and following the weblog nr. 2018 ( Save Time with generalized JDBC datatypes ) i've made my structures in order to achived that. I've declared the field action as SELECT than the table name ... and in the IB set the needed configurations. So when i exec my interface i've got the black/white flag bur if i look at the adapter engine i see that the JDBC adapter is achieved but i got 2 errors " No 'action' attribute found in XML document('action' attribute missing or wrong XML structure) and Exception caught by adapter framework: error processing request in sax parser: No 'action' attribute found in XML document('action' attribute missing or wrong XML structure). Can anybody provide me some help ??? Thanks in advance.

How can read data from my local PC using JDBC adapter

Hi experts.
Actually we don't have permissions to work on RDBMS. So by locally I have Oracle8.0 installed in my pc. so can i update the table in my database via JDBS adapter. If so please describe how and where can I find the connectivity between XI server and my local DB system.
Thanks.

The first question is: Can the XI access your local PC?
In most environments this is not possible.
Connect to the server where the XI is installed and log on with the <sid>adm user (or let an administrator do this). Try to ping your PC.
If this is successful, you have a good chance to connct your database. Follow the description in your database manual, which parameters you need to enter in the JDBC adapter channel.

Stefan

Oracle Function in JDBC Adapter

Dear All
Can we execute an oracle fucntion using receiver jdbc adapter? if yes then what should be the structure
I have gone through following links but the soluiotn is not clear
Using PI - Calling a Function in Oracle
Regards
Sourabh

I think two possible ways. You might want to write stored procedure and inside your stored procedure call oracle function. The second option is as below. In access tag write your query with standard functions. placeholder is to pass values for the variable.
<StatementName>
<anyName action=u201D SQL_QUERYu201D | u201CSQL_DMLu201D>
<access>SQL-String with optional placeholder(s)</access>
<key>
<placeholder1>value1</placeholder1>
<placeholder2>value2<placeholder2>
</key>
</anyName >
</StatementName>
Ex:
SELECT '03.12.2004:10:34:24' "Now",
 TO_CHAR(hiredate,'DD.MM.YYYY:HH24:MI:SS') "Hiredate",
 TO_DATE('03.12.2004:10:34:24','DD.MM.YYYY:HH24:MI:SS')
 - hiredate "Hired since [Days]"
FROM emp;
where to_char is the oracle function.

How to update row by row in Jdbc Adapter sender ?

Hi friends ,
 No i am reading data from a table using select query and resulting data i am keeping in the FTP folder as XML File.
 I want to
 1. to know how many rows i read ?
 2. Update the read completed time in each row of the sender side table .
 ( I am using select * from a table where tag='n' . I am giving this in Query SQL Statement of JDBC Sender adapter processing parameter .
I am writing update query as update table set tag='y' where tag='n' .
 Will it perform row by row ?
 3. Insert in to another R3 System table the rows which i read as a log .
 Can you please give procedure to do that .
 Expecting your reply asap .
 Thank you
Best Regards.,

Hi raj ,
 Thanks for ur reply . I am new to xi . Just i am doing a scenario . I can able to read the ms-sql server table data using jdbc Sender adapter .
 Can i use RFC Adapter to insert the values to R3 table ?
 If i have mapped to rfc fields will it store into the table once we read the data from ms_sql server table using select query of JDBC Sender Adapter ?

Oracle CEP and JDBC Adapter

I am using Oracle CEP 10g on WIndows.
I wrote the following code on CEP:
OracleDataSource ods = new OracleDataSource();
ods.setURL("jdbc:oracle:thin:scott/[email protected]:1521/orcl");
Connection conn = ods.getConnection();
// Check for the existence of a previous customerID
String selectStmt = "SELECT * from STEPS " +
 "WHERE (streamID='" +
 this.customerId +
 "') and (assetid='" +
 this.eventName +
Statement stmt = conn.createStatement();
//System.out.println("-- calling SELECT");
//System.out.println(selectStmt);
ResultSet rs = stmt.executeQuery(selectStmt);This works great, except it is exceedingling slow. I am sending about 20,000 messages to this code.
I think the problem is that I open the connection everytime I perform a select (and later an insert statement).
The server instance goes away after the message has been processed, and I can not save the connection.
Would using an adapter in config.xml prevent this openig a new connection every time a message invokes this code ?
If so, I have never done JDBC with an adapter and I dont understand how to use an adapter to use a WHERE clause to select on variables, since in the example I have seen so far, it places "SELECT 1 from DUAL" into the config.xml and does not explain how to get mix have the SELECT statement interact with code variables or better yet how to get your code to get a connection handle.
Could someone please post an exaqmple of how to use an adapter with JDBC, and possibly how to get your code to access a connection handle from the config.xml ?
Thanks

Hi,
From note : 831162,
Oracle JDBC Driver (classes12.zip / classes12.jar) Deadlocks
Q: I have deployed the Oracle classes12.zip / classes12.jar JDBC driver as per the instructions in the XI Configuration Guide.
Unfortunately, I frequently notice hanging database connections. A thread dump taken according to the instructions in note 710154 shows one or more blocking JDBC Sender/Reciver threads and optionally that the JVM has detected a deadlock.
A: The Oracle classes12.zip / classes12.jar driver is compatible with JDK 1.2 and 1.3 only, but not with JDK 1.4. Upgrade to a current version of the driver (ojdbc14.jar). For details, refer to note 941317.
Make sure that you remove classes12.zip / classes12.jar from aii_af_jmsproviderlib.sda prior to adding the new driver as per the instructions in the answer to question #1 above as you will get a class name collision otherwise (all JARs from aii_af_jmsproviderlib.sda are loaded into the same class loader and the driver class name of both driver versions is the same).
Before deploying the updated driver, ensure that the new version is still compatible with your Oracle database server release. For details, refer to the release notes provided by Oracle.

Bhavesh

Call Oracle Function via JDBC Adapter

Hi to everybody,
using JDBC connection with an Oracle DB, from XI I manage to send messages to execute SQL statements or Stored Procedures. Does anybody know if there is a way to call also an Oracle Function?
Thanks a lot for any help...
Ilaria

Hi Illaria,
I think i agree with Michal. The solution to your problem would be to go for a stored procedure. The link on SDN help only tells us that a stored procedure can be executed and does not discuss about oracle functions.
http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm
So, Stored Procedures, it has to be.

Hi Raj,
To access any Database from XI, you will have to install the corresponding Driver on your XI server.
To install oracle driver, just check this link,
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3867a582-0401-0010-6cbf-9644e49f1a10
The details that have to be entered while adapter configuration if you are using the OJDBC14.jar
The parameters should be mentioned as follows.
Connection : jdbc:oracle:thin:@<IP adress>:<listener port>:<instance name (database name)>
Driver : oracle.jdbc.driver.OracleDriver
Also go through these links for more information regarding the same:

In reciever jdbc adapter config sending data to multiple tables

Hi Masters,
Can u help me with examples step by step procedure of sending data to multiple tables in reciever jdbc adapter .. configuration....
thanks in advance,
jp.

Hi,
My understanding is you are trying to use one scenario for ex a file to jdbc and want to post data into multiple tables.
If you are using Message Prortocol XML SQL format then once you define the data type for one structure then juz right click on the statement name and select Duplicate. This will create another statement in the same data type change the table name and the parameters in the duplicates strucutre.
Document Formats for the Receiver JDBC Adapter
http://help.sap.com/saphelp_nw70/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm
All the other configurations are same simple file to jdbc scenario.

JDBC adapter - update statement

I have come to the conclusion that there is no direct connection between the select and update statement of a sender JDBC adapter, in terms of commit scope.
According to SAP documentation:
"The UPDATE statement must alter exactly those data records that have been selected by the SELECT statement. You can ensure this is the case by using an identical WHERE clause. (See Processing Parameters, SQL Statement for Query, and SQL Statement for Update below)."
But my point is: if select statement retrieves e.g. 5 rows based on a where condition, then the update statement could find 6 rows to update, if a row was inserted a split second after the select, but before the update. Result : a row is lost...
I don't think the select statement puts a lock on the table(s) it accesses, and releases this lock after update has been committed. This would ensure integrity between select and update statement.
Can anybody confirm or deny this ?

Hi,
Have you seen the Isolation level for Transaction handling in the sender JDBC adapter?
Make the Isolation level as Serializable and repeatable Read and the db gets locked anbd until Update happens, no Insertion can occur in the Split Second!

Error while connecting to Oracle db using jdbc

When I try to execute a java class which has to access data in
the Oracle db using Jdbc connection, get an error --
Appln- pathname/filename is attempting to call the OCI function
(opinit) this function does not exist in ORA72.DLL.
Exit this appln ? Yes or No
Both oracle db & java are on the same PC.Would like to know what
can be done to rectify this.
Thanks.
null

The OCI driver 7.3 requires the 7.3 OCI to be installed (this is
part of the client required support files or RSF). The particular
call in question wasn't added to the OCI untill 7.3 so it
wouldn't exist in the 7.2 OCI library.

UPDATE statement in Receiver JDBC adapter

Hi all,
I would like to use UPDATE statement in my receiver JDBC adapter and would like to know how this UPDATE statement works in following case.
1) If i have 10 records to be updated in database, whether Commit happens at the end of all 10 records updation OR it will be for every record update?
Regards

Hi,
Then let me construct my query this way...
i have 10 records that needs to be updated to database, say For Ex: 7 records are updated successfully and 8th record has issue in updating the table.
In this case i would like to ROLLBACK entire 10 records with out committing any thing.
So if i use your 2nd option, it should perform as i expected right?
