Regarding Receiver Communication Channel (Concurrency problem)

Hi Masters ,
In Receiver Communication Channel which is connected to oracle data base ..while updating records Status from N to C . i am getting following errors :
**Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Channel has reached maximum concurrency (5,000 concurrent messages) and no free resource found within 5,000 milliseconds; increase the maximum concurrency level**
Actually we are updating 10000 records status from N to C....... earlier it was updating in 30min now its hanging and giving above error ...... after 3 hrs its automatically displays updated succesfully message .
Can you help me to understand wht exactly happening and at wht level i have to do settings in communication channel so tht it should work properly..
Thanks in Advance.............
Jagannath.

Hi Jagannath
you can specify the maximum concurrency for receiver adapters. This defines the number of messages an adapter can process in parallel on a cluster node.
Enter the number of messages to be processed in parallel by the receiver channel. For example, if you enter the value 2, then two messages are processed in parallel. Default value is 1 and this means only one message can be processed at a time by the receiver channel.

http://help.sap.com/saphelp_nw70/helpdata/EN/bc/bb79d6061007419a081e58cbeaaf28/frameset.htm
increase this parameter from 1000 to a higher value you required and you would not be facing such problem

Problems in IDOC receiver communication channel

Hi,
I am trying to build an interface to get data from 3rd party legacy system using JDBC and post the data into ECC using IDOCS. I have IDOC built in ECC, I am able to import the metadata in IDX2 after creating port in IDX1. But after building the whole interface, I dont see the IDOC receiver communication channel which has to post IDOCS in the ECC 6.0 system.
Please assist.

Query regarding OS Command in Receiver Communication Channel

Hi All,
Consider the following :
1. Sender communication channel picks up file <abc.txt> from /files/in directory. The CC is configured to archive the file in the location /files/archive.
2. Resulting Message is processed successfully in integration engine.
3. Receiver communication channel is configured to place the file in target directory /files/out, and the Run OS command after message processing is set as : "/scripts/FTP_SCRIPT.pl %F".
The above scenario works fine, but I do not understand why it works. :).
I can see (by looking at logs maintained by the script FTP_SCRIPT.pl) that in step 3 %F passes "/files/in/abc.txt" as a parameter.
I believe that the file should not be available in the "in" folder because the sender communication channel would have already archived it. Why is it available?
In what order is XI processing steps 1-3 in the background?

Hello,
If you have selected Adaper Specific message attributes in both the adapters(File sender/Receiver), the same file name which is currently being used will be passed to the place holder '%F' .
and you might have selected RUN OS command before message processing.
Just confirm.

Sreenivas.

Regarding the JDBC Receiver Communication Channel error

Hi All,
While executing Jdbc to Jdbc interface, i am getting error in jdbc receiver communication channel. please see below message for error description..
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Channel 'JDBC_AccntStatements_Receiver', Service 'BS_BusinessSystem', Party '': JDBC Adapter configuration not activated

Hi
According to your Error Message,
Saying that JDBC Configuration is not Active.
Once again cross check all the config is Activated & also Test your Config Using Config Test Tool in ID

Intermittent problems with a RFC receiver communication channel.

Hello.
I want to know how to get the total channel history for a RFC receiver communication channel (in RWB only last 5 calls are available).
We use this communication channel in a java mapping to run a RFC of the abap engine of XI. Sometimes the rfc doesn't work and mapping throws a mapping transformation exception. Then, without a modification, we reprocess the message in SXMB_MONI and it is processed without errors. We think that it could be caused by a huge message volume.
How can I get the maximum number of rfc calls that the rfc communication channel can admit simultaneously. Which parameters have influence in these calls?
Thank you very much.
Alberto.

Error in JDBC receiver Communication Channel

Hi,
I am facing a problem at receiver communication channel of JDBC adapter. I am gettting the error as,
"com.sap.aii.af.ra.ms.api.RecoverableException: Channel has reached maximum concurrency(5,000 concurrent Messages) and no free resourse found within 5,000 milliseconds; Increase the maximum Concurrency Level."
I am having the configuration on 4 different nodes. but suddenly only 1 out of 4 is working fine but remaining 3 are throwing this exception. It says to increase Maximum Concurrency level but i want to send only one message through one channel.
Is there a way to rectify this error. I am in deep trouble.
can anyone help me out in solving this issue, Its very greatfull if you do the needy.
Thanks,
Soorya,

Hello Aarthi,
I have gone through the link which you have provided for me in this regard. But i am not clear why those values,
AFW.Call.maxConsumers 10
AFW.Recv.maxConsumers 5
AFW.Rqst.maxConsumers 10
AFW.Send.maxConsumers 5
JDBC_http://sap.com/xi/XI/System.Call.maxConsumers 20
JDBC_http://sap.com/xi/XI/System.Recv.maxConsumers 10
JDBC_http://sap.com/xi/XI/System.Rqst.maxConsumers 20
JDBC_http://sap.com/xi/XI/System.Send.maxConsumers 10
These are concerned to MS only but not at JDBC adpater.
We have to look at JDBC prospective but not at the MS prospective.
So can you please look into the issue as JDBC adapter perspective.
Its like this that, there are 5000 messages are waiting for the free resource with in the next 5secs and as it is reached maximum concurrency of 1.
So my question here is,
Is there only one option to increase this value to 2 or more?
Or else do we have any other option to overcome this problem.
Please reply to this ASAP.
Thanks,
Soorya.

SMTP Receiver Communication Channel error: connection refused

Dear all.
When migrating processes from XI 3.0 to PI 7.1 we run into the problem that we can't get the SMTP Receiver Communication Channel working on PI. We get the following error in Communication Channel Monitoring:
Message processing failed. Cause: com.sap.aii.af.sdk.xi.srt.BubbleException: Failed to call the endpoint [null "null"]; nested exception caused by: java.net.ConnectException: Connection refused: connect
(The NetWeaver Administrator log shows the following:
unable to call the mailer: com.sap.aii.af.sdk.xi.srt.BubbleException: Failed to call the endpoint [null "null"]; nested exception caused by: java.net.ConnectException: Connection refused: connect)
- We copied all configuration settings 1-on-1 from XI to PI, and double-checked we made no mistakes.
- We confirmed the PI system can in fact reach the mailserver by successfully sending Email from the ABAP stack of the PI system (transactions SOST and SCOT)
- When deliberately mistyping the mailserver URL, we get the error: java.net.UnknownHostException. This makes me believe that the 'connection refused' error we get (after re-entering the correct mailserver URL) is indeed coming from the mailserver. But why would it refuse the connection if it allows the connection from the ABAP stack of the same server? And why didn't we run into any such problems on XI?
Any help is much appreciated!
Kind regards,
Eddy Driessen.

FTP error: Receiver Communication Channel

Hello Experts,
I am getting the following FTP error in my Receiver Communication Channel.
Error occurred while connecting to FTP server: Peer certificate rejected by ChainVerifier
Please suggest.
Thanks,
Anup

Hi Anup,
Problem is with FTPS and not FTP.The SSL handshake needs to confirm that the FTPS client is using the FTPS server's DNS name to access the FTP service since only the DNS name of the FTPS server is stored in the certificate signed by the trusted CA (e.g. VeriSign). it's the way the Certification Authorities works.
If you are using any IP address then try with your host name.

Madan

If I check in the SXMB_MONI in i'm getting the following message .. but the URL whicjh i provided that is fine.. but my doubt is through XI may be it's not able to connect the Target System... .. so, please suggest me...

By default, the SOAP adapter sends the SOAP message with the content type text/xml.
When you check "Do not use SOAP envelope", the default contnet type is application/xml.
You can change the content type like this: Go to the SOAP receiver communication channel module tab. Add the module "localejbs/AF_Modules/MessageTransformBean" before the standard module. Add the parameter name Transform.ContentType and value text/xml.

Error in Receiver Communication Channel in FCC

File Overwriting in File Receiver Communication Channel

Hi,
I have an IDoc to File scenario.
My file receiver communication channel has the following parameters :
- File name scheme = %timestamp%_AOBSD4RL.MES
(I'm using variable substition and the variable "timestamp" is initialized at mapping time with the current time in format yyyyMMddHHmmss).
- File Construction Mode = Create
- Option "Overwrite Existing File" not activated
When two inbound messages result in the same target file name, the second one overwrites the first one although the "Overwirte Existing File" setting is not active in the receiver channel. Is this a bug in XI ? (I'm on 7.00 SP11)
And is it possible to say to the receiver channel to process only 1 message per second so there will no more target file with same name ?
Thanks in advance,
Laurence

Hi Laurence,
There is no such facility with Receiver File Adapter to process single message in one step.
I want to suggest you a may possible way to overcome( it's just an idea), though I never worked with them I think it will work.
As you the file name is assigned to message with timestamp at receiver communication channel step you can schedule the outbound queue in such a way that it will transfer the message in delay.
Try to investigate further more, But i m not sure that Queue Scheduling is supported by SP11 or not.

Shri

Recordset structure in receiver communication channel

Hi gurus!
I have a problem with my receiver communication channel it says "Unknown structure 'Headers' found in document', probably configuration error in file adapter (XML parser error)'"
It's for sure that the problem is in the configuration of the adapter.
My scenario is from iDoc to File and i need to write only one header and many Lines, i made the data type like:
Headers
---Header
Lines
---Line
And the problem is in the configurarion of the recordset structure and the lines below.
If you know another way better to make the data type to acommplish what i've to do, just tell me I just made it that way because i thought it could work.
If something is not clear just let me know, what i more need is the config. of the receiver adapter.
Thanx in advance.
Juan

Hi Juan
If i understand correctly .. you are doing FCC on your receiver communication channel...and the following is your Target Data type
Headers
---Header
Lines
---Line
and FCC parameters you created are as below
Recordset structure: Headers,Header,Lines,Line
Header.fieldSeparator \r\n
Header.endSeparator \r\n
Line.fieldSeparator \r\n
Line.endSeparator \r\n
If the above data is correct, then I would like you try out the FCC parameters in my previous post. Because in the FCC parameters, you used only substructures(Header and Line) and you did not mention the lists ( Headers and Lines). That's why i think it is errored out.
If my interpretation is wrong, please let me know where i went wrong, i will try to look at again.

SSL in Soap receiver communication channel

Hi,
I have a webservices that works fine in Soap UI. The webservice provider uses the SSL, but works like a web browser, doesn´t need to install a certificate before access the webservice.
But when i try to use SAP PI using the soap receiver communication channel, the soap adater return the follow message:
"Peer certificate rejected by ChainVerifier"
I read some thing about using axis to solve this problem but I can´t find anything to configure this scenario.
If someone had this problem and solved it, i will apreciate the help.
Thanks
Fabricio

I Have 2 communication channel:
1) This works fine
Adapter Type: SOAP
Receiver
Transport Protocol: HTTP
Message Protocol: SOAP 1.1
Adapter Engine: Integration Server
Target URL: https://gw-homologa.serasa.com.br/wsacheixml/wsacheixml.asmx
SOAP Action: https://sitenet05.serasa.com.br/WSAcheiXML/WSAcheiXML/ConsultaAchei
2) This doesn´t work
Adapter Type: SOAP
Receiver
Transport Protocol: HTTP
Message Protocol: SOAP 1.1
Adapter Engine: Integration Server
Authentication: Basic
User/Password
Target URL: https://treina.spc.org.br/spc/remoting/ws/consulta/consultaWebService
SOAP Action: blank
Both are https and the certificate is sent at communication time (There isn´t a certificate to install in the Key Store in Visual Administrator)
I read that Axis manage this kind of integration with webservices, because the certificate must be installed at the moment of sending http request.
I don´t know why the first interface works fine an the another doesn´t work, then I´m trying with Axis.
In the SOAP UI both interfaces work fine.
Thanks

Content type in SOAP receiver communication channel

Hello,
so far I thought that the SOAP receiver adapter always sets the content type to text/xml. However now I found out the following strange thing:
If you check the option "without SOAP envelope" then the content type is application/xml. Is there any way to influence this as the receiver of the message only accepts text/xml.
Have you had any similar experience?

hi,
- open SOAP receiver communication channel - module tab
- add the module "localejbs/AF_Modules/MessageTransformBean" or AF_Modules/MessageTransformBean" before the standard SOAP module
- add the parameter = Transform.ContentType with value = text/xml
I'm just not sure if you need to add value = text/xml or "text/xml" so try the second one if the first one will not work
does it work now?

Michal Krawczyk

Error in HTTP_AAE receiver communication channel, PI 7.4 dual stack

Dear Experts,
I am facing the below certificate error in HTTP_AAE receiver communication channel while using the third party (bank) private key. Third party bank server is HTTPS enabled, moreover they have generated the public and private keys on their server, and they shared the corresponding private keys in .p12 format to us. Our scenario in SAP PI is synchronous ABAP Proxy to HTTP_AAE, when I see the message in SXMB_MONI after testing, we get he below certificate error, though we have provided the correct path from keystorage view and keystorage entry in HTTP_AAE receiver communication channel
“com.sap.aii.adapter.http.api.HttpAdapterException: ERROR_SENDING_HTTP_REQUEST, sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target”
We have imported the private key provided by bank in Netweaver admin key storage, by following the below steps.
NWA -> Certificates -> Key Storage -> TrustedCA->Import Entry->Entry Type->PKCS#12 Key Pair->select the .p12 file->import.
Please see the attached doc for related screenshots.
Please experts help me experts as this is on high priority from client, also suggest me if I am doing anything wrong here.
Thanks,
Farhan

Hi Farhaan,
do you have only one certificate or multiple certificate? HTTPS can have 2 or 3 certificates (Root, Intermediate [optional, if any 3rd party person is there in the middle then we can get this certificate] and system certificates).
The issue is with the certificate and it can be because All the certificate is not present or path is not correct.
Please refer the below wiki in which solution is given for this peroblem.
