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.
Regards.

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.

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.

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

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.

Sender communication channel stopped after error "Connection Timed Out"

Hi experts,
in our scenario we have an asyncronous sender communication channel with polling every 6 seconds to an external FTP server.
Yesterday evening a "Connection Timed Out" error came.
After this error the polling stopped but channel in communication channel monitoring still remains green.
So status green but no polling.
To solve this problem we stopped and then restarted channel from CC monitoring.
The channel is configured "manually".
The question is: Is it possible to avoid this problem? Maybe there's a parameter in configuration to set?
After a time out error the channel must go on polling, it should not stop. Or it must shows red status.
Thanks

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.

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.

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?

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.

Files not getting picked up using Sender Communication Channel frm MDM sy

Hi Experts,
XI sender communication channel is configured to pick up any files coming from MDM system from the following path
/XXX/XXX/mdm/mds/XXX/XXX/Material_Master/Outbound/P33/P33_R3_PORT/Ready
Earlier we had the scenario working properly that created idocs in R3 system.(MDM>XI>R3)
Currently i tried to test the scenario again but i don't see an entry in the sxmb_moni or tried checking whether the sender communication channel is working properly it showed polling correctly in RWB.The files are already sitting in the the above path.XI should be picking it up but don't know what the problem is?
I also tried a test in RWB>Integration Engine>Test Message put the payload and it was able to create idocs in R3.So i concluded there is an error in picking up message from MDM.
Is there any log available for the commmunication channel where i can see error info of whether any files picked up or not.
Please suggest me what all can be done to to ensure the CC is picking up the files.
Earlier responses highly appreciated.
B'Rgds,
Sudhansu

Hi,
In addition to the RWB channel check suggested by Aamir, you should also check if the channel is
1) Active in ID
2) Channel is not locked in VA, if it is locked then your status in RWB will show processing started but the files wont be picked up...for more details check the unlocking procedure mentioned in this thread:
JDBC Sender Adapter - NOT FETCHING RECORDS -PROCESSING STARTED
The unlocking procedure is the same for FILE and JDBC....

BIC Module Error in Sender Communication channel for EDI to File scenario.

Hi Experts,
We are working on the EDI based scenarion where EDI files come to SAP PI from partner and then through Split 997 Adapter Func Ack is sent back to the Partner . But we are facing a issue in our sender Communication Channel which is a File Adapter Channel and uses BIC Module for the conversion of EDI to XML .Request if any one can provide any guidance on the below issue coming in sender CC.
Error: Error in BICMODULE-module:Temporary error: BIC XI Adapter call failed. Reason: 2 errors occured. First error: EdiSegmentData read(): Edifact Format not correct : segment must end with \"segment delimiter\" (Segment : ISA).

Hi Abhishek,
Is there any special character present in the EDI file?
the parser is not able to parse the data.
you can check the BIC conversion log for more information.
