File adapter processing in FTP mode

Hello SDN,
I need some info on File adapter working in FTP mode.
What happens when we point to a remote file location that runs on FTP server?
FTP in standard does not support a remote read operation at all. So the only possible logic that strikes me is issue a FTP get command over the file and get the file locally, read it. Does it happen this way? Or SAP has customised FTP to enable the read operation from a remote location directly?

Jai Shankar

Hi Jai,
I am sure you must have gone through this File/FTP help file earlier also. If you read the Procedure section of it, I think it will give you a clear idea what exactly happening there:

How to configure SFTP Adapter in XI?
in that 2 nd reply
there is one option :2. Use the FTP adapter, and encrypt/decrypt the file contents through a user exit in the adapter. Something on the FTP server side will have to do the same.
can anyone please elaborate this one & where can i find user exit for the file adapter.
please help is there any option to provide secure cinnection in file adapter (FTP) like using run operating system command befor or after message processing
Thanks In advance

I think that you can solve in 4 different ways:
-> Using FTPS connection
http://help.sap.com/saphelp_nw04/helpdata/en/e3/94007075cae04f930cc4c034e411e1/frameset.htm
-> Using a 3rd Party Adapter (Seeburger or Aedaptive) for PGP or deploying a custom adapter for PGP
http://www.seeburger.com/9468/
-> PGP OS Level (Installing a PGP software like GnuPGP in your system) Install the PGP software in XI and write the OS command for encryption and decryption at OS level. Call this command in File adapter after or before message processing
PGP ncryption
-> Using an UDF

FILE ADAPTER ERROR IN FTP

Hi,
Iam getting the following error in sender file adapter:
Could not process due to error: com.sap.aii.adapter.file.ftp.FTPEx: 550 *** ERROR *** NO BATCHES FOR TRANSMISSION
Could anyone help me in this.
Thanks &Regards,
Y.Raj

Hi Raj,
1. Check whether the user you are using has access control i.e Read/Write Access from the folder in FTP server..
2. Check it at OS level by directly pasting or pick the files..
3. From SAP end check the user credientials provided in the file adapter i.e username of the FTP server and the Password of the FTP server it is case-sensitive.
4. Try to give the exact path from where the file is to be picked and reactivate the scenario.
5. what is the file size of the file that is going to be picked from the ftp server.
6. Then finally check in Communication channel monitoring detailed log what is the error it was coming and check the log in XI server you can clearly notice the error.
Even some times it will access at OS level but not through the server for this reactivate the adapter and provdie the user credentials and the path once again..

Kishore.

File Adapter , Processing Sequence

Hi All,
 Can you please help me to understand these?
1. When i configure a Sender File Adapter with file pattern *.txt, Does it handle the files one after another? Or does it span multiple threads and processes multiple files in parallel?
2. If i select processing sequence as DATE, does it consider the time stamp also?
3. If a 100 mb file with name BIG.txt created at 1.00 AM,
 and a 0.1 mb file with name small created at 1.10 on the sender system. If 100MB file needs 30 min to get processed,
Then can i assume the second file get processed only after big file completely processed and reached the destination?
Regards
Ganges Leaves

Ganges,
During any polling interval, XI will pick all files matching your Criteria and process them parallely.
Even if the big file is being processed, the next file will be picked up by the adapter if it is available during the next polling interval.
All interfaces are executed independent of the other.
All this is if u choose the mode as Best Effort.

File Adapter going into infinite mode while polling for the file

Hi,
I am facing an issue while the file adapter is reading the data from the file.
If the file from which it is reading has been deleted it keeps on polling for it infinite number of times and also doesn't pops out with any error message. Is there any method that after polling for some time period we can pop out a message that the particular file is not available and then the file adapter should stop polling for the file.Anyone has some ideas about this. Any pointers will be of great help.
Thanks
Vinay

Hi soachd,
As far as I understand polling is infinite process. You need to adopt this strategy if you are expecting some thing to happen all the time or may be when you want to be ready when ever an expected event happens. This provides a real time solution but with the downside of infinite execution.
Hope it helps.

File Adapter--Processing parameter configuration

Hi Experts,
I need to configured the sender and reciever FTP Adapter to Archive a 37 MB text file within a FTP server.
It is taking 20 min to archive the file.
does this requirement requires any change in Parameter configuration(like transfer mode, channel availabilty planning( i am using daily with duration 30 min) to make it fast.
Thank you,
MK

Hi Experts,
To archive huge files using FTP adapter, i looked at the Michal weblog to zip the file :
/people/michal.krawczyk2/blog/2007/02/08/xipi-command-line-sample-functions
please explain how and where to write the below file
@ECHO OFF
7za.exe a -tzip D:\file_cat\%2.zip %1
del %1
and also explain
Zipping a file can also be done with jar.
For example,
jar cvf m.zip m.txt
will zip m.txt into m.zip
No need for any other software as jar is highly likely to be on the XI/PI server...
and how to implement it in the FTP adapter configuration.
Thanks in Advance.

File Adapter-Processing Parameters

can one tell me the difference between and when to use the following processing parameters
poll interval(secs)
poll interval(msecs)
Retry Interval(Secs)
Advanced Mode & Msecs to wait before modification

Hi,
from help.sap.com
http://help.sap.com/saphelp_nw04/helpdata/en/e3/94007075cae04f930cc4c034e411e1/content.htm
Poll Interval (secs)
Number of seconds that the adapter must wait if no files are found for processing.
Poll Interval (msecs)
Additional waiting time in milliseconds.
If Poll Interval (secs) is set to null, processing times will be short and close to real time.
If Poll Interval (secs) and Poll Interval (msecs) are set to null, the adapter is only called once.
Retry Interval (secs)
Specify the number of seconds that the adapter is to wait before a file processed with errors is processed again.
If the value is set to null, then the adapter is canceled if an error occurs, even if a value greater than null is specified for Poll Interval (secs).

SAP XI - File Adapter, Sender, using FTP

Hi. On a couple of occasions we have encountered a situation where the Comms. Channel effectively stops polling, but no error is reported. Making the channel 'Inactive' and then 'Active' does resolve the issue, but I'm wondering if anyone else has experienced this, if there is a way of preventing it or effectively monitoring for this type of issue? We are using XI , SP 19.

Hi Andy,
check for the timeout option in advanced tab of the adapter. Please check for the link given below.

File adapter causes FTP process stop result 0 byte file.

Has anyone ever heard that FTP adapter can cause FTP process to stop and end up with 0 byte file transferred?
We use the normal ftp script to ftp file from external file server place file in XI inbound folder so that file adapter can pick them up from that folder.
We have encounter a few 0 byte FTPed file in our system. One suspecting is the network between XI server and file server might get some interruption. With out just blaming on the network. We would like to know if there is any possibility that it is also causes by our file adapter? Says, it try to read the file that is not yet complete transferring make FTP give up transferring??
We would like to know if FTP process is transferring the file over and file adapter try to read, what will happen? Will it read file with incomplete content and ftp still go on? Or will it stop reading and return back error as the file could not be open? Or it will force FTP process to let go the file??
Best rgds,
Thida

Hi,
>We would like to know if there is any possibility that it is also causes by our file adapter? Says, it try to read the file that is not yet complete transferring make FTP give up transferring??
have not seen the file adapter causing any such problems. So, it looks like a network issue.
>We would like to know if FTP process is transferring the file over and file adapter try to read, what will happen? Will it read file with incomplete content and ftp still go on? Or will it stop reading and return back error as the file could not be open? Or it will force FTP process to let go the file??
Am not exactly sure, but when a file is being created and the file adapter tries to read such a file, the file would be READ and WRITE Locked and so File adapter should not be able to read such a file until the creation of the file is complete.
Also, take a look at the note : 821267 , question 31 for how file adapter processes empty file.

Mainframe Integration using File Adapter (FTP Mode):: ftp commands

Hi,
We are trying to integrate with Mainframe system using File Adapter. (FTP mode). We are able to write the file to Mainframe system but not able to format it properly. We had to provide FTP parameter, ftp.quote site recfm=fb lrecl=150
As per SAP Note 801926 :: XI 3.0 File Adapter: Additional Parameters, the only parameter that can be used is ftp.timeout. Has anyone tried out using other FTP parameters? (like ftp.quote)
Any help is grealy appreciated.
Regards,
Siva Maranani

I am looking at running some OS commands especially the QUOTE SITE FILENAME, and found this OSS note:
https://service.sap.com/sap/support/notes/841704
In this note it says...
"Note that for the File Adapter transport protocol "FTP", the operating system command is NOT executed on the FTP server, but on the server hosting the Adapter Engine."

FIle adapter Test Mode

Hi Guys,
What are the modes available in File adapter sender and receiver mode? what is Test mode for? can you pls send me a link on file adapter attributes?
XIer

Hi,
Processing mode for File sender:
Archive
Files that have been successfully processed are moved to an archive directory.
To add a time stamp to a file name, select the Add Time Stamp indicator.
Under Archive Directory, enter the name of the archive directory.
If you want to archive the files on the FTP server, set the Archive Files on FTP Server indicator. If you do not set the indicator, the files are archived in the Adapter Engine file system.
Delete
Successfully processed files are deleted.
Test
Files are not processed.
Only use this mode to test the configurations of the file/FTP adapter or the Integration Engine/PCK. It is not suitable for productive operation.
 Set to Read-Only
Successfully processed files are given this attribute. Only writable files are processed. This selection is only available for the File System (NFS) transport protocol.
File As receiver you have FILE CONSTRUCTION MODE
Create,Append,Add Time Stamp,Add Message ID,Add Counter.

Archive processed files at receiver file adapter

Hi Experts,
I need to archive(copy) processed messages from the target folder to another folder.
I tried using the Run OS Command after processing and not sure with the exact command.
Can anyone please provide the exact command (syntax) for copying file from the target file folder to another folder.
Do we need any authorization from BASIS team to perform this command in run OS Commandline please.
Note: the original file should not be deleted.
Thanks in advance!
Regards,
Mahakrishnan T.

hi Mahakrishnan Thangam,
I used the OS command feature where FTP is not used and it worked in the way I already posted. When it comes to FTP in receiver file adapter you need a batch file and a script both on PI server. The script will function as follows
1. Login to FTP server.
2. change to target folder you specified in target directory in cc.
command: cd foldername
3.Read the file created by receiver file adapter in remote FTP location. File will be copied to local directory of PI server.
command: get filename
4. Now again change remote directory to archive directory.
5. Copy the file back to FTP server again from local directory to archive directory you want to copy to.
Now from batch file call this script.
Would suggest to read these links carefully

Alter algorithms to meet your requirement.
Hope this solves your problem.

Problems in FTPS file adapter

Hi,
I have configured a sender file adapter to use FTPS.When I lookinto the adapter monitor the corresponding communication channel has a red symbol saying 'Error: Error connecting to ftp server 'dev-db1':
FTPEx: Please login with USER and PASS'.
I have deployed SAP Java Cryptographic Toolkit.
I have added the CA certificate to the key storage.
Any help is appreciated. Thanks in advance
Regards,
Suneel

Hi Suneel,
Looks like in your CC configuration you still have "Connection Security" as none.
You should select one of the 2 FTPS options. Then verify the "Command Order" and check if X.509 is used for client authentication.
Pls check the following for details:

File adapter polling stops after reboot of third party system

Hi,
We noticed that whenever we reboot our third party system, XI File Adapter is losing it's connection to that third party system and polling stops. As a result File Adapter is not processing any files from that particular server.
To fix this problem, we either reboot XI Server or refresh communication channel (Go to change mode and save it).
File adapter is configured to use FTP to transfer the files between Windows Server and Unix Server.
Is there a better way to fix this problem?
Thanks in advance.
Regards
Chandu

Hi,
Make the connect mode as PER FILE TRANSFER in the file adapter.
Connect Mode
Permanently
An existing connection to the FTP server is used permanently.
The connection is reestablished automatically if it is closed by the server.
Per File Transfer
A new connection to the FTP server is established for each file transfer.
