Synch/Asynch Bridge TimeOut

Hi,
I am sending data to R/3 system through XI and waiting for response. If the R/3 takes half an hour to respond will my Synch/Asynch bridge will be still waiting for the response or will it die because of TIME_OUT.
Can anyone let me know.
Regards,
Amar Nemalikanti

Hi,
There is a Time Out for the Sync/Async Communication.
The settings can be done SXMB_ADM -> Integration Engine Config -> Change Specific Config -> Add a new entry
Check the Category SA_COMM, see the help for its parameters.
By default the time out setting is 60 seconds and the maximum allowed is 1000 seconds.
Thanks & Regards,
Renjith.

Do I need to do a BPM / Synch-Asynch bridge ?

SDNers,
I have a scenario where a synchronous SOAP HTTP message will come in with data. Following steps are needed.
1) Call a stored procedure to authenticate on a DB2 database. Possible JDBC adapter.
1a) If authentication fails need to respond with error code in the SOAP-MSG and end.
2) Call another stored procedure to post the data to temporary table and get back a unique ID.
3) Return the response and unique ID to the SOAP-MSG.
Can you please let me know -
a) If I will need to create a BPM for this scenario. If not how ?
b) If BPM is needed - will I need a Synch-Asynch bridge although I have all synchronous communication throughout the process. All the stored procedures to DB2 database are intended to be synchronous JDBC receivers.
Thanks a lot in advance,
Charu

Thanks Sandro, Sudheer, Shweta and Venkat for your inputs.
It certainly looks like there is no way other than BPM even though I have synchronous scenarios - espacially because of the authentication step.
In case some of you are wondering why is not the authentication step and the subsequent step merged -The authentication are maintained in a separate system and hence a separate call is needed.
Venkat - I will check out on the Synch/Asynch bridge.
All - you have more inputs then please share your views.

Http_synch-- file using synch/asynch bridge

I am trying to do the following scenario with bpm ( synch/asynch bridge)
Scenario:
1. Http client calls BPM synchronously (open the S/A bridge).
2. BPM sends the received message to file adapter.
3. Another process reads the files and produces an output file (or I can do this manually).
4. The output file is sent back to BPM.
5. BPM returns the output message back to http synch (closes S/A bridge)
Integration Process Design :
1. Receive Synch (open the S/A bridge)
2. Send Asynch
3. Receive Asynch
4. Send Synch (close the S/A bridge)
When I call the BPM from the http client (QOS is BE or EO) , BPM receives the message and writes the file (so step1 and step 2 are okay). Then http client comes back with no response. That means BPM is not waiting for a message at step 3.
My understanding is BPM should wait on a receive step!
Even if I introduce a wait step after step 2, it doesn't help.
Why does the http client return before the s/a bridge is closed? Am I missing anything?
Please help.
Thanks

Hi,
>1. Receive Synch (open the S/A bridge)
This will again be a receive step with mode as opens S?A bridge.
>Send Synch (close the S/A bridge)
This is a Send Step with mode CLOSES S/A BRIDGE it will not be a Synch step.

My understanding is BPM should wait on a receive step!
it should. Make sure that the file adapter is active. And see if the file has been picked up. Did you check the flow of the message in the BPE? Did the receive step get executed? I think it would have and the problem can be in the mapping.
Just take a look at the Synch - Asynch bridge example in this link,

Synch/Asynch Bridge

Hi all,
Can anyone tell me where exactly Synch/Asynch Bridge is used
Thanx,
krishna

Hi,
Sync/async communication enables a synchronous sender system to communicate with a receiver system that cannot process synchronous messages
Refer this blog
/people/ravikumar.allampallam/blog/2005/02/17/bridging-the-sync-async-bridge-with-fork-xi
/people/sriram.vasudevan3/blog/2005/01/11/demonstrating-use-of-synchronous-asynchronous-bridge-to-integrate-synchronous-and-asynchronous-systems-using-ccbpm-in-sap-xi
There is an example of the Sync/Async Bridge in th SWCV: SAP BASIS.
Namespace: http://sap.com/xi/XI/System/Patterns
The Integration Server receives synchronous messages from a sender and send them to a receiver as asynchronous messages. Conversely, it can send the asynchronous response from the receiver back to the sender as a synchronous response.
As soon as a synchronous message is received from the sender system the process uses a special receive step to open the sync/async bridge, sends the received message to the receiver system asynchronously, and waits for the asynchronous response to arrive from the receiver.
The BPE receives the asynchronous response from the receiver, correlates it with the corresponding query, and activates the waiting process, which then sends the response back to the sender synchronously.
This blog also should give you some idea...

Sync/Async bridge timeout?

Hi,
a ccBPM process produces some timeouts during the last week and i dont know why. The process produces the timeout in the third step:
Step 1: Receive synchronous message via HTTP, open sync/async bridge
Step 2: Mapping
STep 3: Send back response for synchronous message and close sync/async bridge
in step 3 the timeout occurs (we have 1 minute configured for ccBMP processes):

Does anyone know why this happens?
Does step 3 wait until the sender system releases the synchronous message? So only when step 3 is done, the process will be processed asynchronous?

Doubt on Sync-asynch Bridge

hi all,
I was trying to understand the sync-asynch bridge concept and from what all i have read i have come to know that there is a sync-asynch and also asynch-sync bridge.This is used in a scenario say file-rfc-file.But i have done the same scenario without the bridge.I am still not clear where this bridge will fit into.
Can anybody please explain me with suitable examples..
thanks,
Nisheeta

Hi,
File-RFC-file is Async-sync communication. There is nothink like async-sync bridge in BPM. Because for this, 3 steps are needed
1. Receive - async
2. send - sync
3. send - async
But for Sync-async scenario, a Sync-async bridge should opened using receive step.
Example : Http request - File && File - Http response
Steps:
1. Receive - open sync-async bridge --> To receive Http request
2. Send - async --> To send message to File adapter.
3. Receive - async --> To receive message from File adapter
4. Send - close sync-async bridge --> To send Http response
Example : http://help.sap.com/saphelp_nw04/helpdata/en/83/d2a84028c9e469e10000000a1550b0/content.htm
Hope this clears your doubt.

Synch-asynch scenario without bpm's?

Synch-asynch scenario without bpmu2019s can any one help me how to configure this scenario without bpms?

hi ferocious,
That is possible with standard functions and standard module beans.
Possiable1:
From pi 7.1 v , sap provided standard functions like RFC and jdbc of the conversion function group.
Possiable2:
sap provided Standard module beans those are RequestResopnceBean and OnewayResponceBean.

To create an asynch - synch - asynch flow with XI, without BPM

I would like to create an asynch -> synch -> asynch flow with XI,
without BPM.
The solution with RequestResponseBean and ResponseOnewayBean modules in
the File sender communication channel works fine.
But now I would ask you how can I do if my sender is R/3, with IDocs?
Because we cannot use modules in the IDoc sender communication channel,
and I don't want to use BPM.
Could you help me?
Thanks in advance,
Ram.

/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible
Refer to this blog. You may find a way out.
Alternatively, I would rather know the reason behind you not using BPM.Coz its the best way to acheive the desired result.

BPM SA bridge timeout

We have sync RFC calls to an external SAP system and is done via BPM SA bridge. Some very critical business information is exchanged which takes over 30 mts at times.
I was able to set the BPM SA communication timeout to 1000 seconds from 60 seconds default which is approximately 16 minutes. Unfortunately 1000 seconds is the max I can set.
Any idea how I can go about making BPM sync calls to last over 30 mts.
thank you,
Parimala

Hi,
>>>>When you say it blocks lot of resources. Can you name a few.
1. RFC calls with CALL FUNCTION are processed in dialog work processes so if you're using sRFC then one of your dialog processes hangs for 30 minutes
2. in the XI if you use sync communication this means that
you're blocking one queue which is constantly waiting for
the response (and it has to wait 30 minutes) so you block
one queue for such a long time
3. if there is an error in communication with your
external system then what? the XI has to wait? or does it
trieeger error and the whole process has to start
from the beggining ?
use correlations if you can show those people:
>>>> but got a lot of push back

Synch/Asynch with out BPM

Hi All,
I have a HTTP to webservice scenario currently running in production , i.e .,
From the HTTP Application user sends a request to XI . XI makes a SOAP call and sends the request back to HTTP Application .
now I have a new requirement to write the SOAP request message to a JMS channel also.
Let me know how is it achievable with out using BPM .
Thanks and Regards,
KLK

Thanks for the replies , I have to clarify my question
Yes my requirement is to send the soap - response to JMS .
The above blog is File - RFC - File ( Asyn/sync) but my requirement is
HTTP - SOAP -- JMS (Syn/Asynch) .
The current scenario in production my o/b and i/b message interface are synchronus .
I need a i/b asynch interface reciepent for the SOAP response .
Let me know your thoughts
Thanks
KLK

RFC synch/asynch

Hi,
RFCs are synchronous by default. So they use BE as QoS.
How to make them Asynchronous so that they will use EO QoS?
In Asynch case will the RFC response be persisted or only request to RFC will be persisted?
thanks in advance,
KP

Hi,
transactional RFC (tRFC) and queued RFC (qRFC) are both asynchronous. But the RFC Adapter only supports tRFC, which only uses an outbound buffer (it's not a queue) and matches the QoS EO. On the sending system you can use the transaction SM58 to monitor the outgoing messages. The messages are buffered in the adapter framework, if the target system is not available.
As said above, on SAP releases prior to 6.20, SAP IDOCs are the only way to use EOIO.
A tRFC is called by using the additional line 'in background task'.
In the SAP System, there is no different definition for synchronous and asynchronous RFCs. The asynchronous just only use the importing parameters.

Christian

Synch|/asynch bpel process

Hi!
what is thу main difference between synchronous and asynchronous bpel process? I mean, when you create bpel process - you can choice type. Because I dont think that the difference just in invoke and reply activities.
Message was edited by:
kpb

There are other differences too, as in how the processes are dehydrated.
If you are writing processes for a high load environment you should look at the BPEL tuning guides before just creating a bunch of asynch processes. Generally, the asynch processes will be hitting the dehydration store harder.

Synching Blackberry bridge and native email/calendar/contacts

Is there any way to synchronise between the bridge and the native email/contacts/calendar on the playbook? I prefer the playbook's email etc but don't always have the playbook with me, so I end up putting new contacts etc on my bb phone. What I would like to do is synchronise the new contacts etc onto the playbooks native apps when the two devices are connected by bluetooth.

BPM - Synch Asynch Process

My Scenario is File to File and also SOAP thru BPM for File Split. I have to do BPM for file split because of the timing dependency of delivery of files.
Here are the steps in Integration process:
1. Receive File from Sender A
2. Transform this file into multiple files ( In this transformation step Iam capturing Source File Name into separate message )
3. Send all files to the Receiver
4. Send Synchronously SOAP call to the Receiver and receive response message
5. String 'FileName' captured in Step2
and response message from Step4 to another message
6. Send the message from step 5 to the Sender A ( Original Sender )
My Question is Do I have to save the filename in Step2 as a message? Can I do it using Simple type in integration process, if yes, how can I do that.
Someone please explain?. Thanks

Hi,
Save the file name as a message. Anyway you need to send the file name in message right ? And if you want to use it, then use Mapping for the same

Logical persepctive of synch /asynch interfaces

From logical perspective if a particular adapter : eg : JDBC , does not support synchronous processing , then why not create 2 interfaces ,one with sender jdbc and other with recv jdbc. Is this statement correct ?

hmm ok ... but do we not need bpm for this ? or we can count them as 2 sepearate interfaces ?
If there is no relation between the data passed in first flow and then in second flow.....or....if you dont want to correlate the two messages then no need of BPM, you can consider the two as separate flows. Ask your lead or business consultant how the flow has to be.
2) secondly i do not want to connect to database multiple times ,instead i want something like batch processing maybe at
10 am in night , can this be done via jdbc adapters or a stored procedure is needed?
Are you looking for Availability Time Planning (from SP19) functionality?
