File Sender Communication Channel not working

Hi All,
We have one file sender channel which sends file after every 3 hours.
But currently it has stopped the processing of file.
If we see in RWB it shows that "Correctly configured and started",but if we start and stop the chanel it doesnt show any processing started message.
File is there in the folder but the channel doesnt poll the folder to pick up the file.
We have refreshed the cache and activated the channel again.
But still no luck,does anybody have any idea?

Hi Shweta,
Please check the parameters of your File adapter. There can be following possibility if File adapter is not picking the file :
1. File adapter is not active
2. Incorrect File name, Directory name or path,
3. File does not exist in the source directory.
4. If you are accessing file from other server (use FTP protocol) check you have READ and WRITE access.
Thanks
Farooq.

File sender communication channel stop working

Hi Guru,
I have a file sender communication channel. It usually works good. But sometimes it just stop working. And In RWB, it shows no error. If I stop it and restart it in RWB, it immediately works again. This happens once a while. Any ideas?
Thanks,
Meiying

Hi,
option 1--
Do some dummy changes and activate channel and try and perform cache refresh.
If still not working then stop and restart SFTP service,if still no luck then restart JAVA stack
option 2
try to put timeout value in the channel.

Perosnally, I would recommend setting a trace and letting the system telling you exactly why.
Traces are used to analyze runtime errors. By setting a specific trace level for specific locations, you can analyze the behavior of individual code segments at class and method level. This is done with the help of the log configurator service:
Log onto the Java Admin Console
     Services
     Log Configurator
     Locations
     Choose the location (Java package) and the tracing level (severity)
(for example, com.sap.aii.adapter.file)
     Root Location > com > sap > aii > File
     Set the severity and choose Copy Severity to Subtree

PI sender communication channel not reading files from NFS directory

Hello,
I have a sender communication channel configured to read file from NFS directory which is on ECC server. A program in ECC generates the file and puts it on the ECC server in the output directory. PI sender communication channel is supposed to pickup this file and process it. If I give the NFS path as the source directory, I am getting error: Configured source directory '//Server/DIR/OUT' does not exist. I tried putting '
Server\DIR\OUT' too but same error. Do I have to add the NFS path of ECC into PI as logical path?
Any suggestions?
Thanks,
Sangita

Hello Sangita,
Your ECC server is an external system, therefore you need to activate FTP service in that system and use the transport protocol FTP:
http://help.sap.com/saphelp_nw04/helpdata/en/e3/94007075cae04f930cc4c034e411e1/content.htm
You can use NFS protocol when you have a local directory in XI server.

Why is a sender communication channel not required for IDOC and PROXY ?

Hello,
In case of IDOCs, metadata will be available in PI for the IDOCs used both at inbound and outbound.
Why is a sender communication channel is not required in case of IDOC and PROXY outbound scenarios (i.e. IDOC to File or PROXY to file ..) when a receiver channel is required for scenarios like file to IDOC or file to PROXY.
Though this might be a regular question, I am not able to find a proper reason.
Please let me know the reason for the above request.
Thanks & Regards.

You will create RFC destination in ECC , it will have details about PI system details, when ever you send IDoc, ECC will use Port and RFC destination to connect PI Integratiion engine to deliver data to PI.
But when receiver side you will create RFC destination in PI with ECC details, but to call RFC destination and Port we need medium that was the reason we create IDoc communication channel.
Even the same case for Proxy also, but HTTP deastination establish the conection between ECC and PI, but receiver side you have to create XI channel with PI integratioin engine adress to post data.

Raj

None of the file Sender Communication Channels are wotking in Prod-Urgent

facing a wierd situation, since yesterday all of my File Sender Comm Channels have stopped picking up files.This is in Production and was working fine day before.When I check in Comm channel monitoring the Channels are started and Functioning and also shows me that they are polling for the files.But no file is picked though files exist in the directory.These channels have been working fine since months and nothing had been changed since then.Suddenly all of them stopped picking up files.
I have about 10 Comm Channels that pick files, Is this related to Adapter Engine....any suggestions on this would be really apprecated.
Thank You.

Hi!
Check access rights on your files. Try to set them to 777 (using chmod). Maybe this will help.
Problem is, when the XI does not have rights for picking up files, you see no errror message in CC monitoring and everything seems to be ok, but it is not..
We faced the same problem.. And we figured out, that our partner started to upload files with different access rights.

FILE SENDER COMMUNICATION CHANNEL DOESN'T GET FILE

Hi,
I have create a new sender communication channel with ftp file configuration. Server parameter and source directory are correct.
I have also checked file and directory permission (chmod 777)
Poll interval is 600 secs.
There is no error in communication channel monitor (returned log: CC is correctly configured and started).
Process started every poll interval, but no file is picked up.
Why?
Carme

Hi,
What type of file are you processing. Check whether the file type is binary or text mode.
Also check whether the file name you have specified in the CC and the exact file in the directory are the same.
Also check the file processing mode, whether it is read only, delete or in test mode.
If the file is in read only mode when the file first processed, then once the file was processed it would be in read only mode, so if you place the new file it should process, so try deleting the existing file in the directory and place a new file with exact file name along with the correct extension and try to process it.
Also I would suggest you check the exact file extension, by unchecking the radio button in the folder option under the menu tools> Folder options> view-->hide extension for file type.

Communication channel not working -- No Adapter Registered for this channel

Hi Experts,
I see the status of one of my Communication Channels (In RWB Communication Channel Monitoring) as
"No Adapter Registered for this channel".
I saw one of the threads related to this but could not fins a suitable reason for it as our issue seems to be different here.
We have recently deployed the SFTP adapter and PI team is testing this communication channel and they got this error.
I checked and found that SFTP adapter (in the JAVA EE applications) was not working and when I tried to start ,its giving error
failed to start.
additional status message as
Status Details: Cannot load class "com.advantco.pi.af.adapter.sftp.SPIManagedConnectionFactory". Possible reasons: 1) class file cannot be found in the JARs located in the RAR file,
2) class file cannot be found in referenced loaders,
3) failed to initialize some static block(due to unhandled exception),
4) failed to load or there is incompatibility with some native parts, or
5) cannot load a class related to it, due to some reasons above.
Could you guys suggest from where exactly is it trying to pick up the files.
is it u201Cu2026/j2ee/cluster/apps/xxxxxxx/SFTP Adapteru201D ????
Can anyone suggest the possible reasons and the root cause of it
Regards,
Yogi

Hi Yogi,
i am glad you solved the problem.
If you have any issue with the Advantco SFTP adapter, best is to send an email to "support at advantco.com" directly.

File sender adapter is not working

Hello All,
We are facing a problems with file sender adapter. Communication channel is not picking the files from the directory, but the status in RWB for that channel is 'Functioning'. We are not sure whether the channel is locked or any other problewm with adapter. (In Alternate option, we have created copy of that channel and when it is activated, it picked the file )
Can anyone help us how to identify whether channel is locked and any other solutions in this case.
Regards,
Sreenvias.

Hi Srinivas,
The file adapter ( The respective channel) is definitely locked in PI . Ideally for each polling interval a lock is being created and once the processing is over , the lock should be released/deleted automatically to allow further polling interval. If the lock is not released by the system automatically,further polling will not happen as expected. ( This may affect all sender file adapters as well. I would recommend to do a check in al sender file communication channels)
You can see/delete the locks in Visual admin.
Go to Server>Services->Locking adapter and click refresh
The entries for file adapter ( with name $XIAFFileAdapter) should be deleted by selecting those particilar entries and click delete selected locks.
If you have more than one node, then same should be done in all server nodes.
The temprory solution would be creating/copy the existing channel in ID with same properties and assign it into particular sender agreement.
But, the lock may be created again which potentailly stops all your file based interfaces. Hence i would suggest to use Timeout parameter avialable in file sender adapter which termiates FTP session as you defined, This should solve your issue permanently.
The FTP server do have thier own time out settings but if you don't defne any particulat time out in PI, the FTP server forcefully disconnects the FTP sessions which created locks in PI.
Hope this solves your issue.
PS: The same bahaviour would expected for all sender JDBC adapter as well

JDBC Sender Communication channel stop working

Hi all,
I'm facing with a strange problem: I have a db to db scenario (SQL server to Oracle) that has been tested and that was working properly.
But when we started again our tests after some days, without doing any change, the flow didn't start anymore. The problem is in the sender jdbc communication channel:
creating it again with a NEW NAME, and changing the configuration the flow starts again. I try to explain the checks that I did:
- from the runtime workbench the adapter looks ok: green and making polling to the db (obviously without select any record even if we were sure that the select condition was satisfied by some records).
- I tried to simulate some changes re-activating the communication channel.
- clear cache
Nothing was working,the only solution was to re-create the cc with a new name (deleting the old one and creating a new one with the same name is not working as well). But we cannot consider this solution in a production system.
I have several scenarios like this and this problem happened three times in some months and every time with the jdbc sender from SQL server (never with the sender from Oracle).
There is someone that has any suggestion?
Thanks in advance,
Luciana Agostini

Hi Luciana,
There is nothing that you could do in PI that could help because most of the places where there could be a problem like cache or with adapter statuses you have already looked into . For the sake of a second opinion see what prateek srivastava has to say.
Basically a n/w connection problem or at the SQL db level.

Mail Sender Communication channel not polling

Dear all,
In our PI 7.1 Sever, we have observed a issue.
Sender mail communication channel status is green in RWB-->Channel monitoring but the channel does not pick up any mails form the mailbox.
After we stop and then start the channel, it is picking up the mails.
Any pointers on the root casue for this issue and any resolution steps or any SAP Notes to implement will be of great help.
Regards,
Younus

Hi,
Is it like everytime you have to restart the mail channel again and again?
Sometimes it happens, a quick restart will refresh the adapter cache and the messages are processed.
So, its not a problem.

Sushama

Problem in File Sender Communication channel

Dear all,
We have FIle TO RFC scenario, which have been running in Production since long time.
Problem : Many of the time we have obsereved that even if the FTP is up and running , but file is not getting picked from ftp server. File name and all other details are maintained correctly. Can you please suugest me to resolve this issue.
Regards,
Raghvendra

First of all: the connect parameter should be set to 'Per Transfer': this ensures that a new connection to the FTP server is established for each file transfer. That means that you don't loose connection to the FTP server in case of a hick-up.
Second: are there any errors in your communication channel monitoring?

Why my FIle sender Communication channel is inactive?

I tried to edit and save it again, but i can see active at ID but inactive at RWB-->Channelmonitorring..
what to do?

May be in the channel monitoring the channel is stopped. If you are sure that the channel is active in ID and in Start mode in communication channel, then it is a cache issue. Then, perform full CPACache refresh.

Prateek
