XI3.0: Multiple Communication Channels

Hi,
with XI 2.0 one was able to have many endpoints for one interface. For example you were able to have an inbound JMS endpoint and an inbound File endpoint. Both could be configured using the same Business System and Interface.
We used this possibility for testing purpose.
With XI 3.0 you have to create a sender agreement. This can only hold one communication channel. So you have to reconfigure the sender agreement all the time if you just want to send a XML File to an interface that is normally fed by a JMS queue.
Does anybody have any hints how to achieve multiple physical connections to one logical interface?
Regards,
Marc

Hi,
One way would be to create
new Message Interface in XI Repository
base on the old one (for JMS)
the only difference would be the name of the Message Interface
and then most probably you'll be able to create
a second sender agreement and choose a different communication channel
Kind Regards,

Problem of Creating Multiple Communication channels for multiple files

Hi Everybody
I have a very basic doubt but this struck me...
For a file-XI-file scenario,if multiple files are coming from same FTP server but with different names then we have to create multiple communication channels for all the files of different names..but is this a intelligent approach?Can we do something so that only one communication channel can receive multiple files of different names?plz explain in detail if possible ASAP.
I have another doubt as in File-XI-File scenario how the XI understands that a particular file is from this FTP server needs to be send to another particular FTP Server?is it only the name of the file which we give in sender comm channel & receiver comm chaneel which determines this????that means this name should always be same?plz explain in detail if anybody knows?

Thanks Aamir.I understood the solution.
Correct me if I am wrong.......
1)If there are multiple files with different names & different extensions in the sender FTP then we use-->
2)if there are multiple files with different names & different extensions in sender FTP & I want only say files of 2 extension types(say .xml & .txt)then we use-->
*.xml
in one comm channel &
*.txt
in another comm channel rite??
Also I wanted to ask that only two kinda files we can pick up through sender comm channel rite?
.xml and .txt(File content Conversion).Can we pick files of other extensions also?(say .doc,.xls)If we use as u said
then files of all other extensions will also be picked up rite?bt hw will xi convert them into xml?plz explain......
One of my other q is not answered yet.........all these same doubts are there for receiver communication channel.......but you all have not said nething abt the receiver comm channel........plz explain the answers to all these queries for receiver comm channel for a receiver FTP........ASAP......thanks once again.......

AE: multiple Communication Channel instances and message re-sending

Hi All,
My scenario is as follows:
We are running the adapter engine on a server cluster. In the RWB, I have multiple instances of the Communication Channels, for theit various cluster nodes.
My question is:
I have a message in the RWB, which is in System Error state in the AE. If I resend this message from the RWB, does it get queued for the same communication channel instance (as last time, when it failed), or can it get assigned to a new instance?
Hope my question is clear.
Regards,
Puloma.

Hi,
I realized that, a message will always be handled by the same instance of the Communication Channel.
But Exception is when an instance is down. In this case the dispatcher will immediately schedule this message for another instance.
In our scenario, all the instances of the Communication Channel were down, and all the messages were in System Error state, with the error: "Channel not initialized."
In this case, if the message is resent, will it go to the same instance, or to a different instance?
Regards,
Puloma.

Multiple communication channels for file adapter based on user name

I am using this Idoc-to-File scenario, using FTP for sending the files to file server. Target directory is determined by user id which is unique for a field called ASC. Field ASC is a part of incoming Idoc. There are 40 ASC; that means I have 40 user ids/password. Is there way of creating a file communication channel where user id/password can be supplied dynamically. Or there is an alternative to creating 40 different channels, one for each ASC.
Thanks,
Dehra

Hi,
you need to create 40 channels if you have users
as dynamically you can only create:
File Name
Directory
File Type
File Encoding
Temporary Name Scheme for Target File Name
with FTP adapter

In repository what is the use of communication channel templates

Hi People
what is the use of communication channel templates in integration repository? and when we are using that please tell me the ASAP
Thanks & Regards
shekar

HI,
The communication channel template is for the documentation purpose that will give the information about the sender and receiver communication channels in IR. So No need to goto ID and check the related CCs each time for every scenario.
You can preconfigure a communication channel with a communication channel template. You can use the communication channel template as a template to define a communication channel at configuration time.
If you want to create multiple communication channels with some identical configuration data, you should use a communication channel template.
Thanks

XI-Multiple instance scenario -File & SQL sender communication channels

Hi
i have a basic question regarding how file sender communication channel ( where we poll for a particular file pattern either using file/ftp types in a particular subfolder ) or a sql sender communication channel - ( selecting records from a sql source ) would work in a scenario with two active XI instances and j2EE file and sql adapter services running on both of the J2EE servers ?
1. How would the file polling from both J2EE servers - avoid a conflict looking for the same file pattern ? Is there any inbuilt mechanism from SAP to make multiple instances work with the file polling - without a confict ?
2. Simlar question for SQL sender type communication channel ?
If SAP does have a mechanism to handle multiple instance scenarios for file and sql sender adapter based communication channels, is there a link/document on this ?

Hi Karthik,
Please see my comments.
I am just wondering aloud - what will happen if we use a select for update clause in the sql sender adapter communication channel -
Gouri: Yes you can use select + update. In fact that is the right way.
will this ensure that polling from one J2EE instance will lock the selected records so that the second instance does not select the same set of records from the sql server ? Or should we not use a select for update and use a simple select statement ?
Gouri: Yes. SQL DB will ensure that same data will not be picked by another node. As I mentioned earlier use serilizable option from advanced mode.

Party communication channel for multiple stores with multiple user id and passwords in sap pi

Hi Exeperts,
I have a scenario proxy to SAOP . where i am sending some information from my stores to third party company with single user id and password in communication channel.
but requirement is changed now i have 20 stores with 20 user id and password for communication channel.how can i achieve this requirement?
Can i create 20 communication channels for 20 stores or can handle through the party based communication ?
Please help us achieve the requirement.
Regards
Ravinder.s

Hi,
In the SOAP Receiver adapter, you can only store 10 userid/password combinations via Authorization Keys. These are called via Dynamic Configuration via technical name TAuthKey. In your case, for it to work, you need:
1. 2 business components/2 SOAP receiver communication channels.
2. 1 receiver determination with xPath for username to determine correct business component
3. 1 interface determination
4. 2 receiver agreements (one for each cc)
Hope this helps,
Mark

Need to use only one sender and receiver communication channel.

Hello Experts.
I have a scenario where in I have to use only one sender and receiver communication channel to push files from different source directories to different receiver directories.
For Eg;
Sender
D://dir1/file1 --->                  E://dir1/File1
F://dir2/file2 ---->                 G://dir2/file2
H://dir3/file3----->                 I://dir3/file3.
Can this be achieved by using pass through scenario?
Please let me know if the requirement is not clear.
Thanks in advance.
Advit Ramesh

Hi Advit,
I think it is possible. You have to use the Advanced Selection for Source file in the sender channel to define multiple files to be picked up. Also, the Dynamic configuration must also be enabled and used in the mapping so you can manipulate the target directory and target file name based on your source files.

Different message structures on one communication channel

Hello,
we've got the situation where on on single communication channel, we will have multiple message structures. We need to discriminate between them and then handle them according to their structure.
All messages have a header section in which the message type is stored. So I've created a dummy structure:
<ns0:dummy>
<header>
    <message_type></message_type>
</header>
</ns0:dummy>
the actual messges will have a different root element, but you can ignore this by using xpath. So, I've created a sender agremeent with this dummy message as the interface. I have a interface determination with conditions:
/*/header/message_type = MT_A
and receiving interface MT_A. Same for MT_B and so forth. There's no interface mapping in between.
The receiving system now has a receiver agreement with MT_A as the interface. This all works. But in the receiver agreement you set up a communication channel where the message is sent to.
But at this point, MT_A was what the original system sended. All we did was figuring out what message type we're dealing with. Now we need to handle this message as MT_A and using a interface mapping, map it to MT_A_New. We cannot do this in the original receiver determination / interface determination combi, sinse this would mean a message mapping from dummy to something, and we need from MT_A -> MT_A_NEW.
Does anyone have thoughts on how to do this?
Thanx in advance!
Greetings, Walter.

Hello All,
thanks for all your input, it gave me quite a few possible directions to look.
we eventually solved our issue by creating a "generic" structure. It contains the header part (which is the same in structure A and B) and both the A body and B body as optional parts.
now we can make a mapping which only operates on the A part and ignores the B part and also one which does the B part.
<root>
<header>
    <MT></MT>
</header>
<MT_A>
</MT_A>
<MT_B>
   </MT_B>
</root>
we can still define which mapping to use based on the header information. It all seems to work.
Thanks again for all your input!
Greetings, Walter.

Error in generating the communication channel

Hi All,
I am getting the following error while trying to configure the business scenario using the Integration Directory.
Attempt to create object failed

Please help me.
Thanks and Regards,
Soumya.

HI Rajesh,
Thanks for quick reply...
My requirement was to idetify the order number in table which i have generated a sequence to be unique in DB.
Do we have any option to process a single file at a time from the sender location instead of multiple files...i can see processing sequence <bydate> option in nfs but not in FTP.
Please suggest....
Thanks in advance,

I m doing a scenario of collection of multiple idocs into a file.When i m testing this scenario,i m getting a flag successfully executed in SXMB_MONI.But,my file isn't created in my directory.When i monitor the communication channel in Runtime workbench,it's showing error :<b>Channel has not been correctly initialized and cannot process messages</b> for my receiver file adapter?I am not able to figure out the error.Anybody having idea about this problem.
Regards,
Anoop

Hi Anoop
Check it - File adapter is active ? try to Re-activate the same.
Also do CPACache Refresh.
Still problem, tyr out by restarting the Adapter Engine

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.

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.

Naming Convention in the Communication Channel

Hi All.
I have done a FILE->PI->RFC Sync scenerio .
Here I created 2 File Communication Channels and 1 RFC Communication Channel.
Actually, 1 File Communication channel is sender while the other one is receiver.
My question is that can I mention the same file name in both the File , that is, Sender as well as Receiver Communication Channel or do I need to change theri names?
If so, then what will happen if I mention the same File names?
Please help me.
Thanks in advance
