Hi...
i am doing File to JDBC scenario using the stored procedure. While running the scenario,
I am getting below error.
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc.

SYMPTOMS
While using the Microsoft SQL Server 2000 Driver for JDBC, you may experience the following exception:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Can't start a cloned connection while in manual transaction mode.
CAUSE
This error occurs when you try to execute multiple statements against a SQL Server database with the JDBC driver while in manual transaction mode (AutoCommit=false) and while using the direct (SelectMethod=direct) mode. Direct mode is the default mode for the driver.
RESOLUTION
When you use manual transaction mode, you must set the SelectMethod property of the driver to Cursor, or make sure that you use only one active statement on each connection .
For more clarification Please contact you DB .
Thanks

Reg: JDBC to IDOC Scenario Message Mapping

hi Friends
i am designing a Scenario JDBC - IDOC for accounting document interface using ACC_DOCUMENT03 idoc.
i need the mapping program for that to map the JDBC fields with the IDOC fields, so can anyone help me the mandatory fields and the constant values for the IDOC which has to be mapped.Along with this can i know why the constants will be assigned to the fields like Begin =1 , MSGFN = 009 etc how these constants are defined.
Thanks&Regards
suman.

Hi,
for mapping constants in graphical msg mapping, select your target IDOC field..........then you have a constant in the below screen.........click it and then double-click on constant to change the value of the constant field.........then map this constant to your target IDOC field.
for knowing which are the mandatory fields, ask your functional guys to tell you the mandatory fields in data segment of your IDOC and regarding Control segment EDIDC, you have to map fields which have sender and reciever system details.

Reg: JDBC Sender Adapter Locking everytime

HI Experts,
I am facing one issue regarding Sender JDBC Adapter.
I already gone through few SDN LInk and followe the SAP Note 1083488 and few other links and blogs but there is no Use.
I already kept JDBC SENDER>Advance>TASKTIMEOUT = 0 because as per the above note if I am keeping more than 0 then due to some server issues It is difficult to identify the adapter behaviour so I kept 0
Can you please let me know any other Alternate way to identify this solution.

Reg: JDBC Adapter without Update Query

hi friends
i have designed a scenario where JDBC as a sender. i need to configure the adapter without using update query

Hi,
I believe the date field will store along with the time filed in the same column. At least oracle does that.
So in your select query you can write as below(from oracle, as i dont have a ms sql now)
assume
your table name = yourtable
date column = dtcolumn
select * from yourtable where dtcolumn = sysdate - interval '1' minute;
This query assumes that the dtcolumn will be always having the value of the date time stamp when data is inserted.
To be frank you should not do this. I dont understand why you cannot add a column "processed" and add update that. Any specific business requirement?
For best performance, typically in my implementation I suggest using a shadow table from which XI deletes the records. The actual table has the column saying if this got inserted to the shadow table.

Reg: JDBC -- RFC Sync call

Hi All,
I have created a scenario between JDBC and SAP, which is a synchronous communication. In SXMB_MONI and in communication channel monitoring it is successful. JDBC synchronous communication channel is able to fetch the data, However it is not able to push the data to AS400 DB2 database. Can anybody suggest regarding the same. (I want to avoid BPM)
Regards,
Venu V

Thats the way SAP has implemented JDBC adapter.
May be the reason could be that opening a JDBC connection and waiting for a response would increase the performance overhead highly. To avoid this JDBC connection are made async so that once the message is sent, the database connection is closed and table could be used for other transactions maintaining the integrity of data.

I have scenario i.e JDBC to RFC
but i need small calrification like is it possible to trigger the jdbc sender communication channel automatically whne the file tirggerd from the orcle Database
like without giving the any polling intervals CC should poll when the file triggerd.
i am not going to use that file its just a flag to start the communication channel
can we achive this through OS commands ???

Yes you can write script and control the channels externally like give start or stop command at your specified requirement time.
Please see this link
Control Communication Channels Externally without using RWB
Also you can use wget or curl command in the script followed by http url string.
Example:
wget http(s)://host:port/AdapterFramework/ChannelAdminServlet?party=party&service=service&channel=channel&action=start

Reg:JDBC adapter

Is it possible to fetch the data from 5 different database tables using a sngle CC where JDBC is configured on sender side.if yes how?
points will be rewarded for correct answers immediately....
regards
chandrakanth

Hello ,
You either use a select query with join or a stored procedure which will contain the logic to extract the data from multiple tables. But, the limitation in case of stored procedure is u can hv only one selct query in it.
JDBC adapter will be able to holdany select query irrespective of how long it is.
Sample code
SELECT <Table_2>.EID, <Table_2>.FName, <Table_2>.LName, <Table_1>.REC_DAT, <Table_1>.DESCRP
FROM <Table_1> INNER JOIN <Table_2> on
<Table_1>.CARDNO = <Table_2>.CARD
where REC_DAT = <condition>
union
SELECT <Table_2>.EID, <Table_2>.FName, <Table_2>.LName, <Table_1>.REC_DAT, <Table_1>.DESCRP
FROM <Table_1> INNER JOIN <Table_2> on
<Table_1>.CARDNO = <Table_2>.CARD
where REC_DAT = <condition>

using JDBC sender adapter can we update the database of the receiver system ? If so pls provide me the blogs with suitable explanation

Hi Anil,
We can do this absolutely by JDBC sender adapter
In the sender side choose JDBC adapter and give the select query in that corresponding field and write update statement in the corresponding update field.

Reg:JDBC Lookup to pull multiple values

Hi All,
We are trying to pull the data from SQL server and passing it to to RFC through JDBC lookup. Can anyone suggest me how to pull data from different tables and assign it to the target structure (RFC).
Thanks in Advance,
Lavanya.B

Hi,
You can consider this alternative using Stored Procedure...
At receiver side you can execute stored procedure and return the required values in the Response structure. this response structure you have to map to you RFC structure.
i) You can easily handle your select queries, complex logic in the stored procedure.
ii) It is faster than triggering select queries.
You can check these examples for practice and doubts...

Hi All,
My actual requirement is,need to trigger a the database(Oracle9i) on a daily basis for a scheduled time and in receiver side it has to post the xml file to 1) FTP server,2)as mail and 3) to portal as a web service.
Can someone please suggest me how do this scenario.
Thanks in Advance
Lavanya.B

Hi Lavanya,
Please clarify some points
you want to place same data in three receivers or based on conditions you havt ot send data??
You can acieve it using BPM(if you send ding same data to 3 receivers)
or you can acieve it using Enhance receievr determination if sending data besed on Conditions.
Use JDBC Sender define the structure follow stanndarad procedure XI interface Development.
receiver side use File,SOAP,Mail adapter.

My scenario is JDBC to File.
In receiver file communication channel I will be using the Conversion Agent tool and the file name should reflect either the value of the Field say <NAME>TEST</NAME> ,then my output file name will be TEST.CSV or the Busines Service name ie BS_TEST ,then it should be BS_TEST.CSV
Please suggest me on this.

Hi,
Check this blog for using the Busines Service name as your file name:

Reg:JDBC Receiver

Hi All,
   My scenario is Proxy to JDBC (Asynchronous). I have the requirement to delete the old records i.e. to delete the records of the particular fields that are mapped and then insert the new values from the sender side to the same fields.
My structure at the receiver side has already two statements and I have to implement the above functionality to both the statements.
can anyone suggest me how to implement for the same.
Thanks in Advance,
Lavanya .B

Hi All,
Let me state an example say,I have two fields with two different tables and for this 2 statements were used.
TABLE1:
Statement1----
0-U
       NAME----
0-1
TABLE2:
Statement2----
0-U
       ADDRESS----
0-1
Both Name and Address have values of 10 records .Again 8 records are updated to the Field NAME and no updation for the field Address.
Can anyone tell me what will be the status and how many records will both the fields will have now? while using UPDATE_INSERT action.

process limit on oracle database is controlled by

Reg: How to Stop Polling of JDBC Adapter without Scheduling the adapter

Dear Gurus,
Here I am having one requirement. My clients wants to send data from JDBC adapter (ORcale System table) to R3 system via RFC.
His Requirement::
1. He is not telling the time of data flow from Oracle server so that based on that we can schedule the adapter in the Communication Channel monitoring (Availablitiy Time Planning) or Else we can Schedule by deciding the setting of the polling interval time.
2. He is telling that When ever he waants to send the data he will place one dummy file in the File Adapter FTP location so that it will became an Indication for u to poll the jdbc adapter and to transfer the data to R3.
3. Untill he keeps the file or gives indication he doesn;t want to communicate with Oracle server due to some security and it s a most important data base he doesn't want to disturb that Oracle Server as so many business are running on that.....
We Proposed::
1. Atleast you need to tell the scheduling time or poll interval time so that we can schedule our adapter.
but he s not accepting for this
2. Atleast U need to give access for Data base to enter one more extra field like STATUS CODE so that we will add one number and we keep on Update in the Update table and based on that Update table statement it will poll.
but he s not even accepting for this
3. Finally we prposed that to create another table in the Oracle SYstem as Dulplicate Table which is similar to Standard Orginal table when ever he wants to pick the data please keep that data in this Duplicate TABle so that JDBC adapter will pick the data from thsi TABLE instead of picking the data from that standard table so that it will not effect any standard table data in the table.
but he s not even accepting for this
We have done some R & D:::
1. WE approached even through BPM and via switch conditions is one scenario
   FILE RECEIVE >SWITCH CONDITION> RECEIVE AND SEND or else EXIT
2. Using correlation in anotehr scenario means correlating File adapter and JDBC and based on one dynamica value it will goes to SEND STEP ( RECE IVE --> RECEIVE --> SEND STEPS )
Even though we know this...concept that...we jsut tried::
In BPM we can control the flow in XI 3.0 but we cannot Stop the Polling of JDBC adapter at backend because one the data comes from FILE adapter it will keep on HOLD untill it receives the JDBC from Oracle then based on the condition or Correlation it will goes futher SEND step means after that file adapter is picking file or not ...what ever it may be JDBC will polls at backend and brings that data to BPM"
Hence sugest me How to Stop Polling of JDBC Adapter without Scheduling the adapter or else using STATUS CODE Update statements in JDBC Tables

Hi! All,
Finally I decided to do the scenario in two steps:
1: FILE REQ --> JDBC REQ -->JDBC RES --> FILE RECV
2: FILE RECV --> RFC
But I am getting issue while doing first scenario
Desgn :
I have created 2 Synchronous interfaces :
1) FILE 2 JDBC REQ
In this a) out put message is FILE Req
          b) Input msage:; FILE RES
2} JDBC2FILE RECV
        a) Output mesage;; JDBC REQ
        b) Input Msge :: JDBC Response
Mappings:
1) File REQ-->JDBC REQ
2) JDBC RES-->FILE RES
Interface mappings:
1: FILE 2 JDBC REQ--> JDBC 2 FLE RECV
CONFIGURATION ::
1: One Seder File CC
2: Two reciever CC's one is for JDBC RECEIVER and other s FILE RECEIVER
3; One Sender Agreement
4: 2 Recver agreements
5: One Interface Determination and
6: One RECCV Determination
My Question;;
1. First let confirm whether my development steps are right or not ?
2: Another thing s I am not sure reg Configuration Steps means
whetehr one interface determination and one Receiver Determinations are required or not as these are synchronous Interfaces
3: main Issue is::::
If my scenario s FILE2RFC2FILE then I will get RFC response automatically but here issue is this is JDBC
My reqquirement is By sending one Field from fILE to JDBC REQ it needs to send entire TAbLE records as a Response to file as XML
without having Sender JDBC how can I send the JDBC Res to FILE and If that is the case then again JDBC adapter is polling which is contradict to the client requuirement which i explained above.
pleas suggest me the Detailed steps mainly Colloboration agreements and logical routings and
also explain in detail if i can go for BPM
Also give cleear blogs but before giving make sure that it contains detailed screen shots because aIready gone thorugh

Reg http to jdbc Scenario

Hi all,
I am trying to execute a synchronous Http to Jdbc Scenario using MS Access table as my back end.
In design part ,I have followed the steps like
1. Created a http req ,jdbc req, jdbc response ,and then http response in Data types and the in Message types.
2.Created Outbound MI with http req and http response as input and output messages respectively,then Inbound message interface with jdbc req and jdbc response as input and output messages respectively.
3.In Message mapping with Http req and jdbc req as request mappings and jdbc response and http response as Response mappings following the Action and access Steps.
Thats Fine with design part
IN Configuration Part, Since it is a Http Sender ,i didnt create any sender agreement and sender communicatin channel.
Then Configured Jdbc adapter properly and i am able to access my table with that.
While Executing ,I can find that my message is sent in Runtime workbench and can find that Jdbc adapter is Running by showing green flag.
I was trying to send an empid of a table as key and expecting to retrieve the complete row of the corresponding key.
But I could not find the response even though everything is fine with XI.
Where Could be the problem ,where can I see the response from jdbc adapter .
Please help me out in solving this .
Thanks and Regards,
Kalpana

Hi Kalpana,
Can you check this weblog
/people/bhavesh.kantilal/blog/2006/07/03/jdbc-receiver-adapter--synchronous-select-150-step-by-step
This should help you...
Check the Response Mapping,also you have one IM with Reqest and Response mapping...
Also if you have SP16 then you can have sender CC for HTTP also ...
