Exactly-Once Handling in Receiver JDBC Adapter

Hi,
I have doubt abt Exactly-Once Handling in Receiver JDBC Adapter.
For Conflict Resolution as Database.
Why there is need to define table as below ?
In the database where the write-to tables are located you must create an additional table with two columns for this purpose. To define the table, specify the following:
Database Table Name
Enter the name of the table.
Key Column Name
Enter the name of the column in which the key is entered.
Value Column Name
Enter the name of the column in which the key value is entered.
Please explain in simple language.

Hi Abhishake,
Thanks for your reply.
I understant that the tables needs to be created in DB.
But if you read the SAP Docs for conflict resolution. My undestanding is "During Database commit if AS Java is terminated then the message will be in unknown state, for this type of messgaes when the AS Java restarted the behaviour is defined by this parameters. If the message doesn't have primary key, then there is probablity when AS Java will try second time it may get the message in DB so a message can be duplicated. To avoid this condition it is mentioned that you must create additional table with three column".
Please correct my understanding if I am wrong.
My additional table needs to create & how it will resolve the problem.
Thanks in advance.

How to handle BLOB field in receiver JDBC adapter into ABAP table

Dear Experts,
I am working in a synchronous scenario with Sender ABAP Proxy to Oracle Database as receiver via SAP PO 7.4.I will be calling a stored procedure view with fields ID, NAME,Age,*** and BLOB (Image binary).
1. The response from Oracle Database field BLOB is to be stored in ABAP table.Would I have to write any JAVA program to read the BLOB or the receiver JDBC adapter will handle it and store in a table by using ABAP proxy once it reaches ECC.
2. If yes, would the JAVA program have to deal with other 4 fields.
3. Can I use a UDF mapping to this BLOB field.
Regards
Rebecca...

Dear Praveen,
Thanks for your response...
Please correct me if I am wrong.
1. For 1-1 response mapping for BLOB field, I will use just use the below UDF code.
public static byte[] hexStringToByteArray(String s) {
            int len = s.length();
            byte[] data = new byte[len / 2];
            for (int i = 0; i < len; i += 2) {
                        data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                                                                                     + Character.digit(s.charAt(i+1), 16));
            return data;
2. ===Using the byte data, create binary attachment in mapping for abap proxy response===
Could you please share how to create the binary attachment.. I am not clear

Problem in Receiver JDBC Adapter

Hello Gurus,
I am trying SAP -> Oracle Database Scenario.
Where i am passing Id and Email address into the Oracle.
In Runtime workbench, Receiver JDBC adapter Channel, i am able to see that message is in Success.
But if i am going into the Database and looking for that Record, it is not updating that record.
I am not able to understand what is happening.
Please help me out in this issue.
Thanks,
Akhil

HI Akhil,
I know you might have verified alll datat hat will be passing to JDBC...but may I kindly request you to confirm about the table name that was passed in the Mapping once again.
While inserting or Updating are you using all the Key fields..that will allow you to create the unique entry..as if in case if the record is already exists then there may be problem of Indexing...of adding duplicate entry...and due to partial key fields Update statement will not work properly..
Also verify the ORACLE Database log...to get anymore details.
Thanks

High volumes on receiver JDBC adapter

Hi,
We have a RFC ->JDBC scenario where the RFC pulls huge amounts of data from R/3 and sends to XI.
XI needs to upload this data into 5 different Db tables.Each table contains 3000-8000 records with each record containing 10-15 fields.
When we try to run this scenario, due to high volumes of data the JBDC adapter hangs and msgs were in 'holding/delivering' status for long time.
Please advice on possibilities of handling this within XI.

Hi,
We changed the design and now we have only 'INSERT' and we don't have concerns with table refresh now.
I am splitting the records in XI mapping as bunches on 1000 each. But I found one of the tables have more that 1lakh records.
The data volume that we received in RFC is 150000 records(45MB). It took 7.5 mins to process this msg in Integration Engine.
But the messages delivery into Db tables (receiver JDBC adapter processing) is very slow.At maximum it can process 250 records in minute.
Please provide your inputs on this design. Is it Ok to accept 45MB message into XI at one shot? Even though the message got processed(splitted) in IE, they are processing in AE for long time. I believe this will have impact on other interfaces that use JDBC adapter.
Please provide your suggestions on how to improve the design/performance of this interface.
Thanks!

Table name in Receiver JDBC Adapter

Hi All,
I am using receiver JDBC adapter.
But table name consist of " like BPC."#II" .

- Escape Symbol for Apostrophe
The apostrophe character () is a reserved character in SQL syntax and is therefore replaced by an escape character if it occurs within value strings. This replacement character can be database-specific. Typical replacement characters are \ or (default value). If a character occurs that is invalid for the database being used, the adapter triggers an error message (an SQL exception) concerning the SQL syntax that is generated by the database.
- Column Name Delimiter
Depending on the database being used, column names can be enclosed by a special delimiter character, for example, if the names can contain special characters (such as ). This character can be specified at this point. The default setting is no delimiter character. If a character occurs that i

Receiver jdbc adapter:how to implement the insert or update action in a sql

Hi,gurus:
I'm using receiver jdbc adapter now.
You know, we have to gave the action the value 'update' or 'insert',but in our case,the action is variant--update or insert.It decides whether the record exists in the outer database.
Can stored procedure do this?If I use stored procedure,then must I create a stored procedure in the outer database?
Or some other ways to solute my issue?
THanks in advance.

Hi
Use Action UPDATE_INSERT .
This action check if a record exist with same key value then update that record. In case no record with key value found in database then record inserted to database.
look receiver structure

Messages are in hold state due to one message at receiver JDBC adapter

Hello,
I am using a receiver JDBC adapter and trying to send an XML file which has an insert query to insert some data into the database i.e., Oracle 9i.
Here at the receiver side due to one message ( which is in to be delivered state) all other messages are got hold and waiting for long time.
I am getting the exceptions as this,

Can anyone help me out in solving this issue.
THanks,

hi surya,
jdbc channel tries a request for n number of times(no of rettries),if that request fails it will take up the following requests,its not like it will process a request forever.
to be delivered will be resulting if reciever is down or network between XI and database server is bad.
try to ping databse server from XI host system.
if everything is fine then look at the channel configuration->advanced->no of retries of database transaction on sql server.
just redue the count to 1 and recheck.

When would you write a stored procedure in sender/receiver jdbc adapter

Hi Everybody
Can you tell any situation where you would need to write a stored procedure in the query sql statement of sender/ receiver jdbc adapter instead of writing SELECT statement there
why do we need to write stored procedures
thanks and regards,
Anitha

Hi Anitha,
why do we need to write stored procedures
Some times a single SQL statement will not suffice for ur transactions....
Say u want to access from 2 tables and update based on some condition..
or nested select statement...
or u want to update a 2 nd table based on the values from 1st table... etc..
In those places it's preferable for going for a Stored Procedure.
The Stored Procedure can be used in both Sender and Receiver JDBC Adapter.
Still nt clarified do post..

Using Stored procedure in sender or receiver jdbc adapter

Hi All,
Please let me know simple blogs for Stored procedure used in sender or receiver jdbc adapter to get data from 2-3 tables
Thanks

Hi
To work with Store proceudres (SP) you have to create the SP's in database like Oracle, Mssql or Msaccess.
Ususally the SP creations are done by database experts. For more info about "SP" try Googling!
