How to configure pi jdbc sender adapter

Dear all:
i know adapter can poll data at a interval time ,but i have a special requirement.does the interval time that pi poll data can modify in a webdynpro project .if possible.how to do?
thinks very much !

Hi Kevin ,
The way you want may be scheduling the adapter can help you.
checkout the threads :
Scheduling adapters
File adapter schedule

Re: Availability Time Planning for communication channels
check the concept of availabilty time planning concept of XI/PI :

How to configure the Http sender adapter

Now i have look through the sap lib about the http sender adapter
and i know the url is
http://hostname:port/path?namespace=<...>
&interface=<...>&service=<...>&cmd=T&loaderXML=< message object >&end=yes
My questions are:
1)the path in the URL is "/sap/xi/adapter_plain", if not, what is it?
2)the message payload is right?
any reply is appreciated
Thank you very much

Hi Leo,
For a HHTP Scenario:
DESIGN:
1. Create DataTypes for source and Destinations. Create elements for all the text fields of your HTTP Client so that they can all be mapped into the destination file
2. Create MessageTypes for the two datatypes.
3. Create Message Interfaces. The One for HTTP is the sender, Asynchronous ( as no response is expected) and one for File is receiver, asynchronous.
4. Do the mapping. It will be mostly a one to one mapping of the fields.
5. Create the Interface Mapping.
Configuration:
1. Import your Business System under your Configuration Scenario.
2. Create 2 communication channels. One for Http as a sender and one for your receiver say IDoc.
Check these links for the configuration part.

http://help.sap.com/saphelp_nw04/helpdata/en/44/79973cc73af456e10000000a114084/content.htm
3. Do the Receiver Agreement for Idoc. HTTP doesnt need a sender agreement.
4. DO the Receiver Determination and Interface Determination.
Weblog which talk about the same scenario:-
/people/sriram.vasudevan3/blog/2005/01/11/demonstrating-use-of-synchronous-asynchronous-bridge-to-integrate-synchronous-and-asynchronous-systems-using-ccbpm-in-sap-xi - although this weblog is
aimed at explaining the sync-async bridge.. Sriram has taken http-to-file scenario as the example
(use case) and explained it...
Check this SDN tv demo, it has detail of HTTP adapter setup.
https://media.sdn.sap.com/SDNTV/main.asp?mediaId=107
Refer to this link for adapter settings.
http://help.sap.com/saphelp_nw04/helpdata/en/0d/5ab43b274a960de10000000a114084/frameset.htm
You should also have a HTTP client to send message to XI. In the connecting parameters to XI u have to use the URL in the pattern mentioned . U have to give all the configuration details in the URL.
If you give me your mail id or if you can mail me at [email protected], i can send you a HTTP CLIENT.....In which you need to view the source code and change the username and password to send message to XI.

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...

JDBC Sender Adapter

Hi everybody
I have the following error in my JDBC to JDBC scenario; I configured the JDBC sender adapter and receive the following message back. In the Configuration I set Document Name to MT_ScanningStatus:
<?xml version="1.0" encoding="utf-8" ?>
<MT_ScanningStatus>
<row>
<ScannerNb>1</ScannerNb>
<Status>0</Status>
</row>
<row>
<ScannerNb>2</ScannerNb>
<Status>2</Status>
</row>
<row>
<ScannerNb>3</ScannerNb>
<Status>0</Status>
</row>
<row>
<ScannerNb>4</ScannerNb>
<Status>2</Status>
</row>
</MT_ScanningStatus>
I defined the corresponding datatype as follow:
DT_ScanningStatus Complex Type
 row Element 1...unbounded
 ScannerNb Element 1
 STatus Element 1
In the following Mapping I tried to Map this structure to the Structure used to send an Update SQL Statement to the JDBC Receiver to update the same table. A normal Test in the Mapping Tool runs fine but when I enter under source the above incoming Message from the JDBC Adapter I got the following error. I think the incoming message cannot be interpreted. Can someone support me? I read the documentation for the JDBC adapter and also a lot of weblogs and discussion threads. Maybe someone knows a weblog describing more detailed the sender adapter and how to handle the incoming Message!!
Thanks in advance Oliver

Hi Oliver,
>>>>source the above incoming Message from the JDBC Adapter I got the following error. I think the incoming message cannot be interpreted.
do this:
in the test tab try your mapping once more
(the correct one)
then save the source xml as file
next compare this saved file with the one
you get from the jdbc sender
>>>>>Declaration not allowed here.(:main:, row:1, col:8)
and compare the first lines in those two XML files
are they the same?

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.
Brian

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 Configuration

Hi All,
i want to know if we can configure JDBC sender adapter to run only when we ask it to.
Normally what happens is tht the JDBC Sender Adapter polls the database at specified intervals, i dont want that. I only want it to poll the database when i get a file from RFC.
Regards,
Sumit

Hi,
Thank you.I had posted a similar questions a few dayz back and someone said that if we make the jdbc adapter synchronous it would solve our purpose, but it wont.
Bhavesh i went thru ur blog in the mornin b4 postin d question..btw itz a nice blog
Domenico : this is not what im looking for.

How to notify in case SQL query(JDBC sender adapter) does not fetch records

hi,
How can we notify(by alerts or something) in case SQL query(JDBC sender adapter) does not fetch records? In channels logs it only says processing started & finished(no message is created for same).
Thanks,
Mayank

Hi,
1 ) What is exact audit log message ?
2) Try fetching the count in SQL statement if there are any valid records it will give the count.
May for testing you can use <TEST> in update statement.
3) Have you used taskTimeout parameter ?
4) Are multiple channels polling on same table ?

How many times does the JDBC sender adapter retry ?

Hi All,
How many times does the JDBC sender adapter retry in the ' Retry Interval' specified .
I know that it retries after the time specified in the ' retry interval' , but if it again fails after the first retry will it retry again and again .And while doing it will it block the next Select query which should get executed.
Thanks & Regards,
Rahul

Hi,
The no of times to be retired on failure of message is default 3 times.
You can set this in Visual Administrator->Server->Services----> SAP XI Adapter

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,

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.

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 - NOT FETCHING RECORDS...

Hello Experts,
I know this was answered in a separate thread (JDBC Sender Adapter - NOT FETCHING RECORDS -PROCESSING STARTED).
However, my question is, Is there a way that we can be notified if a channel has stopped fetching records?
or is there a reporting tool that can be used to check/monitor if a channel is not processing any messages?
Thanks & Kregards,
allar

Hi Sreedhar,
Thanks for your reply.
These case is not being captured by our alert configuration because its not throwing any error.
in the communication channel monitoring, we see only something like this..:
3/16/09 8:25:19 PM Processing started
3/16/09 8:34:20 PM Processing started
3/16/09 8:33:55 PM Processing started
3/16/09 8:32:54 PM Processing started
but no error is being displayed nor sent.
Also, there was a case that the channel just stopped fetching, even though everything is active.
example log:
3/12/09 8:32:54 PM Processing started
We're looking for ways on how we can trap these scenarios as early as possible, get us notified and perform adapter-lock release when needed.
Regards,
allar

JDBC Sender Adapter : java.sql.SQLException: Cursor state not valid.

Hello all,
We have configured JDBC Sender Adapter which fetches around 10K records with poll interval 1hr from DB2 System .
It was working fine,suddenly it started throwing an exception in Adapter Monitoring :
Error during conversion of query result to XML: java.sql.SQLException: Cursor state not valid.
It is not fetching any records.
Without changing any configurations when we tried to fetch to around 1000 records it's working fine.
For 10K records same exception persists
What could be the reason ?How to resolve this issue?

JDBC sender adapter: Update before mapping

Dear all,
following scenario:
in a database we have a field called "statpi". We pick all messages that have statpi = 0 and
update the data record to statpi = 1 via UPDATE function in JDBC sender adapter.
Every select statement is limited to 100 data records for each message in PI.
But if one data record is wrong and the mapping failed, of course the complete mapping failed.
My problem: The update function of the JDBC sender adapter has already updated the
data records, although they didn't have been send to target system.
What I need is following thing: The adapter should send the messages and after PI has mapped
the message and send it to target system, the UPDATE command should be executed.
In my opinion, this is only possible with BPM, but I am not familiar with Advanced mode in JDBC
sender adapter and "Transaction isolation level". Is there any workaround for this?
Thanks
Regards
Chris

The job that change the DB will be fixed on a certain time. We need to configure

The adapter should poll every hour. Of course we will have some errors before the
support is able to fix this problem, but because of one message each hour this should
not be the main problem.
> - You could do following: pass the values with an error flag, so you can handle this in receiver application,
I am using the function formatNumber for the field that could raised the error. But to chekc if I am able
to do a workaround here and let the target system fix the error sounds like an interessting possibility.
> - Do a split mapping and create a file where you drop any wrong lines
Also interessting. You mean that all "good" record should be mapped to struc1 and the bad one to struc2.
