JDBC Sender Adapter - Single Select and Single Delete

Hi,
I have the requirement where I have to select the single row (or 1st row) from database through JDBC Sender Adapter and delete that record after selection in single polling.
Please help me out with proper SQL query or with any other approach.
Thanks and Regards,
Vijay

I think in SQL select statment you have something like Select TOP number....where number is 1,2..
The detailed syntax for the SELECT clause is as follows:
SELECT [ALL | DISTINCT] [TOP nExpr [PERCENT]] Select_List_Item [AS Column_Name] [, ...]
for more details...check out..

PI 7.1 JDBC sender adapter huge load from DB select

Hi,
We have the problem that the JDBC sender adapter is selecting a huge amount of data from a Oracle DB. The Adapter seems to be able to cope the load but when sending to the integration server it causes problems. We found values to adjust but I dont think increasing them is a good solution.
My question is:
Is there any way to send the data in blocks with using the PI standard JDBC adapter ?
Thank you and regards,
Andreas

Hi,
You can use the below parameter in JDBC sender.
   Specify additional Parameter Names and Parameter Values in the table.
Due to messages of large size it may cause issue
Following are the parameters to be set in the table to limit the message size per polling:
●      msgLimit :
●      maxMsgSize : SAP note 1253826.
●      maxRowSize : SAP note 1253826.
Additional parameters are published in SAP Note 801367.

Problem with JDBC Sender adapter

hi guys!
I´ve problem in PI 7.0, with the JDBC Sender Adapter, execute select sentence and update status in Oracle database.
In RWB Message Monitoring and SXMB_MONI I can't see any message.
Someone have any idea how to fix it?
Thanks in advance.

Hi David,
First check on the sender communication channel, if no data has been picked up by PI on channel,
then check the configuration of channel in the ID, especially select query.
If that is ok, then ask the sender application team(oracle database team) to run the query on their side
and to check if they are getting any data.
There could be the possibility of error in data also.

How to update two tables in a single call using JDBC Sender adapter

Hello All,
The scenario is, database entries have to be selected from two tables and at the same time those tables have to be udpated with the flag.
We are using JDBC sender adapter and in Select Query, we are fetching the data by joinin the two tables.
Update Statemtent: We can only update one table using this statement.
Is it possible to update two tables using the Update Statement without using Stored Procedures.
Let me know.
Regards,
Sreenivas.

Hi Sreenivas,
> Is it possible to update two tables using the Update Statement without using Stored Procedures.
Yes its possible through join statement

Jdbc Sender Adapter and Acks

Hi,
am I right in saying that the JDBC Sender Adapter can't request XI system level acknowledgements. Due to this it is necessary to establish an integrations process fed with the data from the sender adapter, sending it to the target system and receiving an acknowledgement?
Kind regards,
Heiko

Hi heiko,
a JDBC sender adapter cannot be configured Synchronously and so, what you are stating sounds perfect
If you want an update back to the database after execution , BPM is one way .
But, if you are looking to update some info immediately after sender adapter finishes its exectuion, then UPDATE statment can be used.

JDBC Sender Adapter Threads and DB connections

Hello,
I have got a few questions regarding the behaviour of the JDBC sender adapter.
Suppose I have configured a short polling intervall of 10 seconds. On the first poll a message is processed. How does the JDBC sender adapter behave when there is a second poll after 10 seconds and data is available? Does it wait until the first poll has been processed completely or does it start a second thread processing a second message in parallel? If the latter is true, would a second database connection be retrieved or would both threads share one database connection? What would happen if a large number of unprocessed threads were waiting?
Kind regards,
Heiko

hi heiko,
whether the first thread is successful or not automatically a new thread is created after the polling interval.if the previous thread is accessing a data the database would lock that one for theat thread so until the lock is released the other thread has to wait for it.so you can see the thread waiting in SAP WEb GUI.There you can see a green indicator on the status column corresponding to the service.
so a new service is created after the pollling interval irrespective of the pevious service's result and it waits in the queue till its resource is otained.
configuring sender jdbc to poll a databe is not an advisable one that too this short polling interval.this will increase the queue length and obviously cause performance issues...........

Jdbc sender adapter hangs and starts showing "Processing Started" forever

Dear ,
We are facing some issues with jdbc sender adapter channel on production system
Environment : XI 3.0 SP 20 + HP-UX 11.23 ia64 + Oracle 10.2
Sometimes it hangs and starts showing "Processing Started" forever on communication channel monitoring .
There is no error log for this.
If i stop it and then start it , no use.
If i copied this to a new one then it works.
I have found few SAP note like 1078420,1083488 , but my system is already at higher patch level.
Can you please advise me something as we are facing in production frequently.
Regards,
Sandeep

Hi Sandeep,
This problem even we too faced in our project and thought of many stupid things finally found that the JDBC adapter is LOCKED.
Check in the Visual Admin >Cluster> "LOCKING ADAPTER"
we get a option of Display Locks .Check for an entry with
NAME : $XIDBAD.JDBC2XI
reset the locks and restart the CC ,now it works fine.
Note 1083488 - XI FTP/JDBC sender channel stop polling indefinitely(04/04S)
Thanks

JDBC Sender adapter - message split

All,
Scenario:
Oracle Stage table - PI - ECC or R3, (depending on a particular value the record goes to ECC or R3 to post a transaction).
After the record is picked, flag is updated and depending on posting the transaction on SAP, the flag is updated in the stage table.
With the JDBC sender adapter, multiple records are picked up depending on the select statement in the sender comm channel.
I have the following rek.
Now the message is in the AE, before the message enters IE, I would like to split the messages
This would help me in resubmitting the failed (failed to post the transaction) records.
Is there any way that I would be able to do it?
Any guidence...
reg

Hi Naveen,
An alternative way , instead of splitting the multiple record being picked up in a single poll, you can control the number of records being picked. By using the following statement in the sender cc
SELECT * FROM .... UPTO ROWS < 20
so that only 20 records are picked at a time. and resubmit the set of 20 in case it fails.
You can go for this method if it suits your requirement.

Fundamnental question on jdbc sender adapter

Hi ,
I have a scneario like
DB System ³ JDBC Adapter ³ XI -³ RFC Adapter ³ SAP R/3 --³ True ³ response thru same RFC adapter ³ XI BPM will call JDBC Apdapter with Update statement
False ³ response thru same RFC Adapter ³ XI BPM will call File adapter with Append
now when i use send jdbc adapter , i wld need to have a status flag in my database which would be update when ever data is transmitted sucessfully else the same data would always be picked up .
i want to know do i need to create a reciever jdbc adapater too for this . because when ever i use sender jdbc adapter and this must be a very common situation . that i have to update the table so that the rows are not picked up again . jdbc senser has an update statement . writtng an updtae query will it not solve my problem.

Hi Amit,
A JDBC sender adapter has 2 essential fields,
1. SQL Statement
2. Update Statement
Your SQL statement will contain your SELECT statement and once your SQL statement is executed, UPDATE statement is executed. This is done so that records that have been selected by the SQL statement should not be selected again as the JDBC sender adapter will poll over the database for every poll interval.
If you want to SELECT something from your Database, then you will have to go for a JDBC sender adapter.
But, if you want to insert/update your Database, then you can go for a JDBC receiver adapter.
Multiple insertions are possible for a JDBC receiver, but multiple Selection queries (different select queries) are not possible for a single JDBC sender adapter.
Just check these links to understand how JDBC adapters work,
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm">Configuring the Sender JDBC Adapter</a>

A few initial steps required to be followed for your Scenario are:
1. Then create a sender agreement using jdbc o/b interface.
In receiver determination specify ur bpm as receiver.
In interface determination specify the abstract interface tht u created for jdbc.
(u should copy the jdbc interface and then create abstarct interfce of it)
No receiver agreement required for BPM.
2. Create receiver determination, using BPM and the abstract interface for legacy tht u created,
Receiver as legacy system.
Create Interface determination and receiver agreements.

JDBC Sender adapter question

Hi,
Scenario: JDBC-XI-R/3
I am trying to run the JDBC sender adapter every 3 minutes based on the poll interval to select rows from Oracle db.
In the select and update statements when I use the rownum < '11' and flag condition (Y or N), then I see XI is picking up 10 rows in a two times and I see two parallel processes in SXMB_MONI.
I want XI to run only pickup 10 rows for every 3 minutes and update only 10 rows in Oracle to "N" from "Y".
When I take out the rownum condition from update I do not see this issue.
<u>Update statement:</u>
Update <TABLE> set status_flag = 'N' WHERE status_flag = 'Y' and rownum < '11'.
Can some body point me in the right direction ?
Thanks
Steve

Hi there,
See if this works. Though I never came across such a scenario, I can think what to be done in this case.
Create a staging table as same structure as from where our JDBC adapter is picking up the data currently.
Whrite a tigger(after delete) on staging table to call a stored procedure.
stored procedure will select the data from source table and insert them in to staging table (rownum<11) as well as update the flag column in source table.
Now load the staging table initially from source table with only 10 rows (one time process). Configure your JDBC adapter on staging table. In update sqlquery field of JDBC adapter write delete statement for all the data from staging table to be purged, as there will not be more than 10 rows at any time and after each time the adapter supplied Delete statement will purge the data so you dont have to worry about selecting 10 rows or updating 10 rows from JDBC adapter. As every time the trigger after delete statement will fire and load only 10 rows from source marking those 10 rows as read_already status.
NOTE: for Calling stored procedure from trigger follow your database SQL reference documentation.
Thanks.

JDBC Sender Adapter - Records sent one at a time

Hello everyone,
Here's a summary of my scenario JDBC > XI > RFC.
My select statement (JDBC) looks like this:
SELECT * FROM BATCH WHERE STATUS='Y'
The problem is, whenever it returns multiple rows, the RFC can only accept one record at a time (1...1), so I need to pick up the records from the DB and send them one at a time.
Currently, this is how the output XML looks like:
<?xml version="1.0" encoding="utf-8" ?>
<ns:SQL_RESP_MT xmlns:ns="http://www.pharmaindustries.com">
<row>
<number>200000000472</number>
<status>Y</status>
</row>
<row>
<number>200000000473</number>
<status>Y</status>
</row>
<row>
<number>200000000474</number>
<status>Y</status>
</row>
</ns:SQL_RESP_MT>
Instead, I need each row to be picked up and sent one at a time.
<?xml version="1.0" encoding="utf-8" ?>
<ns:SQL_RESP_MT xmlns:ns="http://www.pharmaindustries.com">
<row>
<number>200000000472</number>
<status>Y</status>
</ns:SQL_RESP_MT>
<?xml version="1.0" encoding="utf-8" ?>
<ns:SQL_RESP_MT xmlns:ns="http://www.pharmaindustries.com">
<number>200000000473</number>
<status>Y</status>
</row>
</ns:SQL_RESP_MT>
<?xml version="1.0" encoding="utf-8" ?>
<ns:SQL_RESP_MT xmlns:ns="http://www.pharmaindustries.com">
<number>200000000474</number>
<status>Y</status>
</row>
</ns:SQL_RESP_MT>
Does anyone know the changes I need to make in my current SELECT statement or the JDBC Sender Adapter to make this possible.
Thanks in advance!
Glenn

Thank you all for your replies. I'll check out your link in a bit, Phani. Thanks!
A SpliByValue won't work since the BAPI Header is (1...1).
Luckily, during testing, I found out that the BAPI (BAPI_PRODORDCONF_CREATE_TT) handles multiple lines in one of the subelements of the header so that was where I mapped the Rows.
I might need to trigger multiple BAPIs in the future, so I'll take a good look at your suggestions, but for now, I'm marking this question answered.
Warm regards,
Glenn

Event Handling in JDBC sender adapter

Hi,
please help me in this scenario.
Scenario is Third Party will update the Header and Item values in to Database table.
Once the update is done , a program will run in Thrid party system and it will update the Event Table with the primary key value of the DB table.
So my JDBC sender should be looking for the event table updation. Whenever there is an update in the event table the JDBC sender should automatically kicked off and it should select all the field in the DB table where the primary key = Event table.primary key and the values will be generated as an Idoc.
1.How will i achive this scenario.
2.How to configure the JDBC sender Adapter which gets triggered automatically when there is an updation in event table.
please advice.
Thanks,
Sujatha

Hi,
>>2.How to configure the JDBC sender Adapter which gets triggered automatically when there is an updation in event table.
There is way to control the Communciation Channel externally. Refer this help document http://help.sap.com/saphelp_nw04/helpdata/EN/45/0c86aab4d14dece10000000a11466f/content.htm.
Or alternately you can create a query that always queries only the updated record and configure the JDBC adapter which would periodiocally look the DB...

How to use sql variables in jdbc send adapter??

Hi,
i wanna use a variable in the sql statement in the jdbc send adapter.
i know i can key sql statement in the "Query SQL Statement" in the jdbc send adapter.but i dont know how to use variables in the sql statement.
i mean, for example, the sql statement is "SELECT * FROM t_student WHERE READFLAG = 0", but now i wanna instead of "0"(the value of the READFLAG) using a variable.
and if i can use a variable to replace the "0"(the value of the READFLAG above sql statement), then how can i send a value to the variable??
request help in the regard.
thx in advance.

Hi,
Use the place holders to pass the data at runtime. Check the below structure for more details.
Hope this helps.
Thanks and Regards,
Kalpesh
<root>
<stmt>
    <Student action="SQL_QUERY">
      <access> SELECT * FROM t_student WHERE READFLAG = '$FLAG$ </access>
      <key>
        <FLAG>0</FLAG>
      </key>
    </Student>
</stmt>

JDBC Sender Adapter - Transaction & Parameterized Query?

Dear Experts,
I'm curious about the JDBC sender adapter in SAP PI.
As I see from the document and have been searching in the Internet, The default procedure of the sender JDBC adapter is to first run a SELECT/Store Procedure query then update the records that have been read before.
Configuring the Sender JDBC Adapter - Advanced Adapter Engine - SAP Library
What I want to ask is:
- What is the database transaction used for the SELECT and the UPDATE? I mean what if the SELECT is successful and the records have been sent to the IE, but the UPDATE failed. This way, the next polling run, the same records could be read again. Is it possible? Are the SELECT and UPDATE query atomic (if one fails the other fails too)?
- Is it possible to have a parameterized query / stored procedure in sender JDBC adapter? Because seeing at the default procedure, there should be at least a field that will be used as a flag (for example the processed field needs to be updated to '1'). Something like:
          - SELECT * FROM table_a WHERE docno > $last_doc_no
                         $last_doc_no is a paramter or variable from PI
          - EXEC sp_do_something ( $param_a, $param_b )
                         $param_a, $param_b are parameters or variable in PI
Thank you,
Suwandi C.

Hi Suwandi,
all action to database are in one transaction and thats mean if one failed all failed.
And it is possible to have parameterized storied procedure. You sould send something like
<?xml version="1.0" encoding="UTF-8"?>
<ns0:mt_proc xmlns:ns0="http://aaaa">
   <statementname>
      <stProc action="EXECUTE"/>
      <TABLE>PROCEDURE NAME</TABLE>
      <access>
         <param_in isInput="1" type="some_type">input param</param_in>
         <param_out isOutput="1" type="some_type"></param_out>
      </access>
   </statementname>
</ns0:mt_proc>
