Hi,
I developed an* RFC to JDBC, async interface*
My intension is to+ send the RFC data to two different tables in different databases+.
Is this possible?

See this link for creating jdbc structure on the target side.
http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm
Possible. Since you need to send two diff databases, you might have to do mulitmapping. You can do mulitmapping without BPM. create two different target messages. Each must have its own jdbc receiver adapter.

BPM: Multiple synchronous receivers

Hi Friends,
   I am trying a scenario : File --> XI > RFC(Multiple Receviers)> File(single).
   Can i send the message to multiple synchronous receivers using BPM. My Scenario goes like this...
1). Send file to XI.
2).Use BPM to send it to RFC(Multiple Synchronous Receivers).
3).Send this response to Asynchrounous Receiver ( Write the response to a File using time stamp. So that all the response messages can be written) .
   Is it possible to do this using BPM... Ofcourse i have done a scenario for Multiple Asynchronous receivers using receiver determination and block step in BPM..

Hi,
You can use send synchronous call in your scenario.
The point is, there can be multiple synchrounous calls from the send step.
You would need a way to distinguish the 1st response from the second response. Therefore,we need to make use of correlation.
After the send step, we need to use a receive step(with correlation), which will receive only the response corresponding to the correct request.
Basically we are using the receive step with correlation here, to make sure that, we donot receive and process, the 2nd response(or 3rd or 4th response) for the 1st request.
You said, your scenario is not working. Where exactly are you getting the error.

Multiple client receivers

Hi Experts,
I have a requirement where the SENDER is SOAP and the receiver is RFC.
Sender send the data and it should be bifurcated to 6 clients based on some condition.
Previously I have created a rule in receiver determination to send the date to multiple receivers which are existed in the same client.
But now here they want to send the data to multiple client receivers based on the condition.
Do I need to create the CC and receiver agreement for each receiver or is there any other option available ?
Please help me out with this.
thanks and regards,
praveen

Hi praveen,
Yes. You can handle this in the same way by creating the condition in Receiver determination.
But here you need to create separate Interface determination and receiver agreement for each receiver. You can use existing RFC Communication channel in Receiver agreement.

File to RFC with multiple records using BPM Scenario Error...!!!

Hello Guru's,
I have done the File to RFC with multiple records using BPM scenario as per the Materiel available in the sdn.sap. This involves BAPI (BAPI_MATERIEL_AVAILABILITY). I have done exactly the same what is their in the materiel. SXI_CACHE is also giving return value " 0 ". File is getting deleted from the source directory, but no file in target directory. SXMB_MONI is also showing no error (black Flag). BPM is also error free. Checked the interfaces also.
Can any one tell me what mistake would i have done.
Thanks in advance.

Hi,
There is one similar discussion I found,

Error with Asynchronous RFC call to JDBC

Hi all,
We are working on a scenarion where in we have to make an asynchronous RFC call to JDBC.
We have configured RFC sender adapter following this weblog
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
We have created data types only for the database as RFC does not require any data types.
And also we have created message types,message interfaces accordingly.
In Message Mappping,we mapped the export parameters of RFC to the access fields of database message type.
Also we have created sender agreement,interface determinations etc.... accordingly
And for sending RFC request asynchronously we followed this weblog
/people/swaroopa.vishwanath/blog/2006/12/28/send-rfc-to-sap-xi-150-asynchronous
Once done with all the above steps we could able to trigger the RFC call and caught with the following errors in SXMB_MONI and no errors are seen in communication monitoring
SOAP Error:

the above errors are shown as part of request mapping..
Can any one please let me know what other configurations do we need to do?
I did not map the RFC import parameters,do we need to do that
Any help in this regard is really appreciated
Rgds,
Santhosh

Hi,
I am really happy to hear that the problem with mapping is resolved.
Now as per your requirment It needs to be aynschornous RFC--> XI ---> JDBC call. In XI you should map the RFC Export parameters to the traget structure of JDBC.
then the question is to how to trigger the RFC Function Module in R/3 to XI.
Plesae follow below steps to trigger it from SAP R/3
1. Create a RFC in the R/3 system
2. Configure the SM59 and Sender Communication channle as given in the Michal's blog. Also test if it is succesful.
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
3. Import the RFC in XI
4. Do the mapping to the target strucutre
5. Configure the JDBC receiver adapter
/people/sameer.shadab/blog/2005/10/24/connecting-to-ms-access-using-receiver-jdbc-adapter-without-dsn
6. You can trigger the RFC from R/3 sytem by using
Async Call - in ABAP program use below syntax to call RFC. Here the export parameters will be passed on to XI which further have mapped to JDBC.
CALL Function "RFC Name" IN BACKGROUND TASK destination <sm59 destination>
COMMIT WORK.
Sync Call
CALL Function "RFC Name" destination <sm59 destination>

JDBC(Sender)-XI-RFC (Request) RFC (Response)-XI-JDBC(Receiver)

Hi All,
JDBC(Sender)-XI-RFC (Request)
RFC (Response)-XI-JDBC(Receiver).
Need some solution for sending email for successfully completion of scenario after updating SQL DB Table.
Let me explain the scenario:
We are pooling the SQL DB table to pull the records and map the records to RFC request parameters, after successful Posting the entries in R3 HR, RFC response contain the same with E (Error) S (Success) records status, we are updating the same in SQL DB table, I implemented the complete scenario without BPM with the help of module processor in Sending JDBC Adapter, scenario is working fine but now we have to send the successful mail to our support team with status contain Number of success, Error and total records as email.
I need the solution how to implement the same requirement in current scenario.
Is their way to do something with the RFC receiver adapter module addition to send the successful mail or generating Alert with all the description?
I am at PI 7.0 SP12 with HP unix box.
Thanks in Advance for creative idea
With Regards
Sunil

Hi Bhavesh,
Thanks for your help and your blog is really helpful. I implemented the UDF for generating Email Alert but this alert is generating before Updating the SQL Database, is their any way to generate alert after updating the SQL.
Actually in my scenario we are sending the data from SQL to R3 by RFC and again updating the SQL status whatever the RFC return, after successfully updating SQL we need to send success email to support people but if we are sending the email before updating the DB then their will be problem.
JDBC receiver after updating the SQL DB returns the response with No. of row updated but how to capture this response, if we can capture this response then we can send email through email adapter even their is one more problem, In my scenario I am counting the number of rows with status S and E and sending the same in alert email but if are sending email after updating the SQL DB where can hold the row count value and use it while sending the email.
Implemented the scenario without using BPM..i am using sender JDBC module processor for Syn-Asyn bridge.
Even I do not find the link to reward point. Please let me know how to do it.
With Regards
Sunil

Rfc(Syn)- BPM- JDBC connection breaks for job in 2Hrs

Hi All,
I have a scenario Rfc(Syn)->BPM->JDBC.
Problem i am facing is after 2Hr of execution of scenario. SAP & XI connectivity breaks down.
But to process full data it requires 5-6Hr connectivity because store procedures taking time(for 500 records).
Is there any solution for above problem?
Can we use ABAp Proxy instead of Rfc(i.e. ABAP Proxy->BPM->JDBC), If possible How?
Thanks & Regards

hi,
>>>>I have a scenario Rfc(Syn)->BPM->JDBC.
sync??? you can/should only use sync
if the response time is around 30 seconds
so change the interface to async
>>>>Can we use ABAp Proxy instead of Rfc(i.e. ABAP Proxy->BPM->JDBC), If possible How?
yes but you still have to do it in an async way

Multiple event receivers with a list

Hi All,
If there are two item event receivers attached with a list and event is cancelled by event receiver that trigger first, will second event receiver be invoked? As per my understanding that second event receiver will not be invoked.
I have a requirement where in case first event receiver cancel the event, second event recever should still be invoked.
do anyone has any idea aroound it?
Regards Amit

Hi, Amit KM.
http://msdn.microsoft.com/en-us/library/gg749858.aspx
Notice the following details:
Synchronous event receivers are called in sequential order based on the sequence number specified during event binding. This applies to both Before and After synchronous events.
Asynchronous After event receiver threads are initiated in sequential order based on the sequence number. However, there is no guarantee that they will finish in that same order.
An asynchronous After event can start at any time after its associated user action is performed. It may start before, at the same time as, or after the Web request is completed.
After a user initiates an action in the SharePoint user interface, and before SharePoint Foundation executes the user action, the synchronous Before events are raised. If there are multiple synchronous Before events, they are raised in the order specified
by their sequence number. Similarly, synchronous After events are raised after SharePoint Foundation executes the user action. These, too, are raised in the order specified by sequence number. As you can see, all synchronous events are processed in the same
thread as that in which the user action occurs.
Asynchronous After events, however, are processed on secondary threads.
So you're completely right that if the first event receiver has cancelled the operation, the second event receiver will never been executed.
In your case if you want second event receiver(B) to be invoked regardless of the first event receivers'
(A) result you can easily swap the sequence numbers for those event receivers.
Event Receiver Sequence
The event receiver sequence specifies the order in which an event receiver is executed in cases where an event triggers multiple event receivers. For example, if you have two
ItemAdded event receivers bound to the same list (one from Assembly "1" and the other from Assembly "2"), the event receiver that is bound with a lower sequence number is executed first. A practical example is adding an event receiver to a
system list that already has a system event receiver bound to it. In that case, you assign the new event receiver a higher sequence number.

Multiple Email Receivers for Error Notify

Dear Gurus,
Do you know how to set up multiple mail receivers for error notify? I tried out by using u2018;u2019 and u2018,u2019, and neither of them works.
Thanks!
Mao

Yes, this is possible. You should be able to use , or ; to separate the recipients. However, this functionality has not worked until version SAP 7.00 build M26.11 of the product.
Which version of SAP CPS are you using?

Multiple queue receivers with disjoint message selectors - portable?

Hi all,
I was wondering whether an application that uses multiple queue receivers with disjoint message selectors would be portable across different JMS providers.
I fear it's not - at least the spec clearly states that the implementation of message delivery to multiple receivers is provider specific, and I couldn't find any comment that this would be different with disjoint selectors. But I wanted to check with you - maybe I missed anything?
What could be an alternative then (in case you want to avoid multiple queues)? Using a topic with durable subscribers?
Regards,
Sabine

Hi Nimo,
accepted - as long as the JMS spec requires the JMS provider to support multiple receivers. And that's exactly the point where I'm not sure...
Literally it states:
"For PTP, JMS does not specify the semantics of concurrent QueueReceivers for the same queue; however, JMS does not prohibit a provider from supporting this."
The formulation "does not prohibit" makes me think that JMS allows providers also not to support this, for example, to throw an exception when a second consumer is created for the same queue, or not to serve it at all with messages as long as the first consumer is active. Not that I think it would be a very useful implementation - I just want to know if it would be possible. In that case, the application would not be portable.

Sabine

Multiple jdbc credentials : setting AM pool config parameters on runtime

Hi
was working with multiple jdbc credentials. In the custom JDBC cookie session factory, i try to set my AM configuration parameters , and pass this on to the env info provider , as instructed in the samples. But if i try to pass the JDBC Name , or configuration parameter etc , it refuses to recognize the connection. I have to specify the DB username, DB password and jdbc connection url string for the settings to actually take effect.
I tried using data sources as well, but it in vain.
Is this probably a bug , or is this an issue with how i have implemented it.
code sample with createSessionCookie method of customJDBCSessionCookieFactory:-
Hashtable env = pool.getEnvironment();
env.remove(Configuration.DB_USERNAME_PROPERTY);
env.remove(Configuration.DB_PASSWORD_PROPERTY);
env.remove(Configuration.DB_CONNECT_STRING_PROPERTY);
env.remove(Configuration.JDBC_CONNECTION_NAME);
pool.setUserData(null);
EnvInfoProvider provider = null;
String dbSID = (String)request.getAttribute("dbSID");
if(dbSID.equalsIgnoreCase("SID1")){
provider = new DynamicJDBCEnvInfoProvider( "myJDBCName");
session.setAttribute( Configuration.JDBC_CONNECTION_NAME, "myJDBCName");
cookie.setEnvInfoProvider(provider);
.............................................................

KUBA - were you able to resolve these issues and if so are there any lessons learned you can share?
I'm hoping someone from the ADF team can answer our original question including guidelines for setting pool parameters and how to monitor the pool's performance while running in production.
thanks

Servlets and multiple JDBC connections...

Hi Guru's
I want to perform multiple JDBC queries simultaneously from my servlet. Let's say I have a connection pool containing JDBC connections. Now what I want to do is to use each of this connections simultaneously to perform queries in parallel.
What is the best way to do this??? create multiple threads, one for each query, and then collate results when all threads are finished???
Has anyone does this before or know of any links or samples which I can look at??
your help much appreciated...
Many Thanks

Thanks but further questions....
But take care:
multithreading might only work parallel if there are
multiple processors - otherwise the thread fragments
will be processed one after the other until they are
finished.I agree. My server has multiple processors hence multi-threading.
Why do you need to perform the queries
simultaneously?
wouldn't it work too when you perform the queries one
after the other?To speed up performance. Sequential processing is too slow at the moment.
Hope you don't try doing so inside one single
database...yes inside a single databse.
Do you have any links to sample example etc..??? Importantly are you aware of any issues when one does this type of multi-threading from servlet. i.e does it clash with servlet's threading model etc...
I am aware of how servlets multithread requests and am quite familiar with them. Just wanted some examples on multithreading JDBC connections from servlets and how I can wait for all threads to finish before collecting results....also wanted to make sure that there are no other issues....
further help will be much appreciated.....

Behaviour of multiple queue receivers on same queue

I have been trying to find out what exactly the jms specification states about having multiple queue receivers registered on the same queue. Some books and people say that one is only supposed to register one queue receiver per queue, if this is the case then one might as well use one topic subscriber per topic (what is the utiliy of a queue then).
I believe that one is allowed to register multiple queue receivers on a queue, and a message will only be consumed by exactly one and only one queue receiver, thus allowing for true parallel processing. This is the behaviour I have observed when using jms on both JBoss and Weblogic (and apparantly is the same on Websphere).
I have looked at the formal JMS spec from sun and they dont make it clear what the behaviour of multiple queue receivers on queue is. Can somebody PLEASE help me clear this up.

The behaviour is undefined by the spec. Here is what it says:
"Although it is possible to have two sessions with a QueueReceiver for the same queue, JMS does not define how messages are distributed between the QueueReceivers."
However, multiple receivers on a single queue is a very popular design pattern. A typically pattern is to use the queue as a worklist and for work items to be posted to the queue. There is then a collection of workers who are registered as queue receivers picking out their work items from the queue. These workers are processing in parallel and as the workload increases you respond by add more workers.
This pattern is usable where message ordering is not important and that the workers are stateless.

Multiple JDBC connection pools

Hi
I have WLI application ( 7.0 ) and another J2EE appliction configured on WLS (
7.0 ). If I have multiple jdbc connection pools configured to access different
( or even the same ) databases, I am unable to get the connection to execute a
sql query in the J2EE app. The connection pool gets initialized properly during
the server startup and I can see them in the console but when I try to acquire
a connection from the pool for execution of a jdbc stmt, I am unable to obtain
a connection. Did any one succeed in configuring mulitple jdbc connection pools
and WLI and another J2EE app to run together on WLS 7.0? Any suggestions are welcome.
Thanks
Sreeram

Well ... It boiled down to ACLs.

Flat File-to-RFC question, multiple RFC calls for one file.

Hi guys,
I'm quite new to XI / PI and I have a question regarding a File-to-RFC scenario we're trying in NW PI 7.1.
We have a flat file which has two lines with two fields each, let's take this as an example :
001,001
002,002
The files needs to be converted to XML and then transferred to the RFC program which will update a table with the values above.
In the ESR I've created 3 data types (z_row1,z_record1 and z_fileinput1), 1 message type (z_file2rfc_ob_mt), 1 message mapping (z_file2rfc_mm), 2 Service Interface (z_file2rfc_ob_si and z_file2rfc_ib_ztestpi) and 1 operation mapping (z_file2rfc_om).
In the Integration Builder (ID) I've created everything required (The sender and receiver communication channels, sender and receiver agreement, receiver determination and interface mapping).
We're also using content conversion to convert the flat file to XML, this does seem to work because I see all the lines/field in the message when it gets into PI. The problem is that the RFC can only accept two fields at a time and only the first line gets updated. I see that only the first line gets sent to the RFC.
How can I make the RFC call for each and every line ?
Thanks !!

Create the RFC with table, which takes multiple lineitem as input and update the table in single call.
If you want response back then call RFC as synchrounous else in Asynchrounous mode.
By doing this in single call it will update the complete table.
