FTP Exception

Friends,
I am picking a file via FTP into XI. From XI I am trying to send to my XI directory and R/3 directory. When I execute the scenario I am able to pick the file and load into XI. From XI I am able to send into my XI directory but I am unable to send into R/3. I am using FTP for sending the file to R/3. I am getting an error which states "Error: Message processing failed: java.lang.NullPointerException".
I have checked the userid, pwd, credentials repeatedly. They are fine. Any help would be appreciated.

Hi,
I think, some security issues with FTP connection with R/3.
Try to ping the SAP directory from FTP Server and check the availability.

FTP exception: Can't open passive connection: Permission Denied

I have a File sender adapter, with FTP as transport protocol.
The adapter polls a directory each 60 seconds.
All works perfectly but sometimes I get the following error :
Channel CC_GBL_FlatFileSender: Error connecting to ftp server ...: com.sap.aii.adapter.file.ftp.FTPEx: 425 Can't open passive connection: Permission denied.
And 60 seconds after, no more error.
Any idee of why I get this error occasionally ?
In the sender file adapte, data connection is set to Passive. Do I have to set it to Active ?
Thanks in advance,
Laurence

Hi
Data Connection
- Active
In active mode, the server establishes a data connection from its data port, port 20, to an end point chosen by the client.
- Passive
In passive mode, the client establishes a data connection to the port required by the server.
The default setting is a passive data connection. Only change this setting if you have a specific reason. This is what is recommended by SAP.
It is possible that Passive FTP mode may terminate session.
In this mode the server "listen" on a data port (which is not its default data port) and to wait for a connection rather than initiate one upon receipt of a transfer command. The response to this command includes the host and port address this server is listening on.
In the FTP protocol two ports are normally used, 20 and 21.
Port 21 is the control channel in which requests such as PUT, GET, and PWD are sent to the server.
Port 20 is the data channel in which actual files, folders and directory
listings are sent.
Normally, when you connect to an FTP site, the site establishes the data
connection to your PC (the client) on Port 20. However, if the site allows
passive transfers, you can have your PC establish the data connection. It is
recommended that you use passive mode for most transfers.

How to disable parsing for FTP uploads?

I would like to upload documents into iFS using FTP, but I don't want them to be parsed during upload. How could I disable parsing for FTP uploads?
Thanks, Daniel.

Hi, Are you using FTP inside or outside of Firewall. We are facing problems in ifs uploading when the users are outside of the firewall. This problem does not exist if we are using port 21, but since this is a well know port, we choose to use something else.
May be you can share with us on how to configure IFS to enable ftp ( except port 21 ) outside of firewall.

Anyway to force FTPS only for FTP

Is their anyway to force my users to use FTPS vs FTP. I do not see this
as an option in the restrict.txt. This server is behind a firewall but
I do not see how I could restrict this via the firewall. Anyone have
any idea if this is possible.

I think I have figured out this question. Although I now have another
question. I can force secure connections via the ftpserv.cfg file.
My new question is I would like force all of my users to connect using
FTPS except a few accounts which are mainly scanners that AFAIK will not
do FTPS. Is it possible to make exceptions like this based on account
or IP or do I actually need to setup another FTP server.
Thanks
Andy
Sorry, there is not a way to tell NWFTPD that some users must use FTPS and other users can use regular FTP. It's an all-or-nothing kind of setting.
Gathagan suggested SFTP/SSH, which is a good option, but I suppose your scanners might not do that, either. But you could set NWFTPD to only allow your scanner users (regardless of which protocol it is) and let NWFTPD support regular FTP, and tell all your other users to use SFTP (part of SSH) instead. You'd essentially get your desired end results, though you have to administer 2 services to get it done.

Outgoing FTP problems

First, I'd like to apologize for my crappy english.
Well, we're having troubles with the outgoing FTP connections in BorderManager. With the filters unloaded, the FTP works flawlessly. Now, if the filters are loaded, we can only connect to FTP servers that listen in port 21. The exception (with the packet type ftp-port-pasv-st) works perfect, but if we try to connect to a server that listen in port 27, for example, we can authenticate, but listing the directory doesn't work (in other words, the connection in the data channel never gets established). We have created a new packet type for the port 27 (following the example), and with the stateful filtering enabled, and it doesn't work. BorderManager doesn't let us choose the two options relative to FTP in stateful filtering, though, arguing that there are only for FTP connections (port 21, in other words).
Any ideas?
Cheers,
Javier

The right way is to target the filter exceptions you need. Using
Filter Debug techniques is how I would go about it. (I show some
examples in my BMgr filtering book). The idea being that you show
packets being filtered, so you know what filter exceptions to open up.
FTP is not the simplest application to allow with filter exceptions,
since it uses both control and data ports. The default stateful FTP
exceptions take that into account in their design, but once you vary
from the default ports I wonder if you have real problems making
stateful exceptions? Anyway, you could open up the control port to
the target server address in one exception, and try making it stateful.
Or a pair of non-stateful exceptions, one with non-standard FTP dest
port, and the other with that port as source port. The data portion
could be a problem for you, but you might allow all IP from the target
server, and replies back out.
PKTSCAN on the server, with Wireshark on a PC to read the data easily
might be useful for seeing what ports are being used.

BI publisher report : why "Database Usage Tracking Summary" repport is empty ?

Hi everyone,
I'me using BI publisher intergated to Grid Control12c (R3), trying to get "Database Usage Tracking Summary" report folowing Oracle documentation (http://docs.oracle.com/cd/E24628_01/doc.121/e24473/usage_reports.htm#EMADM13568)
And I have 2 problems :
1) FTPburst delivery is not working, sftp is configured but still have the folowing error
Echec de la distribution.

2) Since FTPburst delivery is not working, i decide to try mail delivery. The delivery itself is working but the report is empty (see Sortie1.xls in attachements)
So i don't know why is it empty.
Can someone guide me ?

Hi,
Thank You for your quick reply. The table permission was alright.
Its very strange that, we configure usage tracking in obiee 11.1.1.6.0 using enterprise manager and that how all document says. And then it should automatically update the "NQSCONFIG.INI". But it was not updated there. So we need to change all configuration settings in both "Enterprise Manager" and also in the "NQSCONFIG.INI". Then it works fine!!
Thanks,
BK.

File Adapter Overwriting the output files

Hi All,
I´m using a File Receiver Adapter to write flat files on to an FTP. Same Communication Channel is used for all types of output files (As per the business requirement the file name(
MzOutput.txt) shud b same for Deliverz orders, Purchase orders etc...). The receiver legacz szstem reads one file at atime and deletes it. So if i´m writing a Deliverz Order File, i have to wait until the file MzOutput.txt gets deleted and then i have to write the next file using the same name. in order to acheive this, i had used a module processor which waits until that MzOutput.txt gets deleted. Mz problem is
As there are ´n´ no of orders waiting in the queue, if at 12:14:00 the MzOutput.txt gets deleted, then two threads which check for the existance of the MzOutput.txt file finds nothing and tries to write at same time. as a result, first file got overwritten by the second file.
I dint check the indicator OverwriteExisting File in the CC configuration.If i use two different CC channels to write the same file, it is giving FTP Exception which is true.
I´m loosing few deliveries as a result of the above case. Can anzone please help me out in this regard?
Thnx in Advance
Anil

Hi Anil,
Why dont you write the files with 'Add time stamp' option on for the file name and then the third party/legacy system to read the files in the order which they were created.?
Another option will be to write these files into a folder with these Add time stamp option/counter option and make a shell script check the folder for the MzOutput.txt file exists in the folder from where the third party/legacy system reads the file and once it has deleted the existing file, then ur files shud be moved in the order in which they were written n the temporary folder.
This will avoid the queue of messages in the adapter engine.

Importing LCA applications issues

Hello everybody.
In the last few days I've been working with the LCES2 Linux virtual appliance made available by Adobe and I tried to import a fairly complex application developed with LCES 8.2.1.
I stumbled across a few issues I'd like to share with you.
The LCA archive was created with LCES WorkBench and I had no issues with previous versions of LCES; in LCES2, I had to import it using adminui [LiveCycle Archives (8.x)] and then, using LCES2 WB, I had to create a new application and import Processes and Resources from the server.
Once the operation completed, I noticed the following:
1) FTP Exceptions are not handled
I had a couple of FTP "Get to filesystem" and "Put" operations whose "FTPConnectionException" was not handled and caused a LCES exception; as a workaround, I had to remove the exception and "re-draw" it as to point again to the handling block (and it worked).
2) SubProcess renaming
The main process had a subprocess named "PDF/A Operations" which, once imported into LCES2 WorkBench, was renamed (in the [Applications] view) as "A Operations". This seems to be a cosmetic issue since I did not have to change the invoking block as to reflect the change of the name.
3) Accented characters
In both a "Send with Document" email operation or in a simple assignment (Setvalue/Execute) I had an expression which contained accented characters (eg, à or è); I had to edit the message/assignment as to retype the offending characters (which got depicted as []) as to let LCES2 handle them as expected). The same went for the GeneratePDFOutput which suffered from the same "disease"
4) Missing Font
Since the original project was developed on a Windows 2003 server, I had to change a couple of fonts (namely, the "Times New Roman" one) in a form since this font does not exist under Linux by default (and I did not want to spend a lot of time by importing the missing fonts into the Linux box)
5) Import issue
I had a process who got incorrectly imported into the new LCES2 environment; by "incorrectly imported" I mean there are some operations (which existed in the LCES 8.2 one) which have not been imported into LCES2. I've still to fix it but I think a simple XML export from LCES WB + Import *might* fix it.
If you have suggestions/opinions, please let me know.
Have a nice Xmas time.
Rob

J2SE Local Adapter Engine

Hi,
We are using the local adapter engine to send and receive files from a FTP server. However, the outbound/receiver adapter is throwing this ugly Java/FTP exception:
Feb 28, 2006 1:02:58 PM ...sap.aii.messaging.adapter.ftp.FTPCtrl [Thread-20] Info: ftp server returns reply '220 Service ready'
Feb 28, 2006 1:02:58 PM ...sap.aii.messaging.adapter.ftp.FTPCtrl [Thread-20] Info: ftp server returns reply '230 User logged in'
Feb 28, 2006 1:02:58 PM ...i.messaging.adapter.XMB2FileProcessor [Thread-20] Error: java.lang.Exception: ftp client test failed with 'com.sap.aii.messaging.adapter.ftp.FTPEx: User logged in'
As you can see the FTP server returns a nice 220 (Service ready for new user.) and 230 (User logged in, proceed.) response.
So how come the adapter throws an exception like this here? Can someone try to explain?
Tnx,
Roberto

Hi,
Actually, your message is truncated so i can't view the complete message,
But i may suggest,
1. In the FTP server did you mention the read,write,append authorization to the userid you are refering in the sender file adapter? Typically i use guildftp as a ftp server and that has options for all these authorization.
2. Do you have any firewall or proxy installed locally,
3. Can you write the sender adapter settings and paste the error again as its truncated from the right side.

Anirban.

In built web server

Hi,
Is there any way to host .asp pages on the built-in web server?
I'm building a web site on a PC at work but might need to work on it over the holidays at home on my Mac so need to find out if I can run the pages localy.

Thanks, Charles. I knew I had read that somewhere,
but wasn't sure. I assume I still need to use the
other third party software for email and FTP servers?
I see OS X has its own FTP sharing, but I've read
it's kind of clunky to use. Any thoughts?
I don't know anything about setting up FTP, except that it's somewhat insecure (passwords in plain text), and apparently somewhat difficult to set up. But you may not even need FTP. Unless you want other people to be able to put files on your server, you could just put your files for download into the web site and serve them up that way.
If you're thinking you'd need FTP sharing in order to access your own web pages on the server, that's not true. You can use SSH, which is much more secure. Just turn on "Remote Login" on in the System Preferences on the server. OS X has a built-in sftp client, if you're comfortable in the Terminal app. Otherwise, there are GUI ftp clients that also do sftp.
As for mail services, I'm not really sure. OS X comes with Postfix, and I've set it up to send email, but never receive. There's a package called Postfix Enabler that enables Postfix and also sets up POP and IMAP services. I've never used it, though, so I have no idea how easy or secure it is (i.e., how hard it is to configure so you're not running an open relay).

B2B : Hub trading partner model

Dear All,
We are facing an issue while using the hub model.
Use case :
1# We need to send an EDI 850 document from TP1 and TP2 to TP3.
Source : TP1 , TP2
Target : TP3
We configured the agreements between following.
TP1 --> host TP --> TP3
TP2 --> host TP --> TP3
The files are getting generated successfully.
But we could not have the Source TP name in the ISA segment from TP value. We see the HiostTrading partner name.
What configuration change we need to do , So that TP1 / TP2 name will be shown in generated ISA segment fromTP element.
Thanks in advance.
Siddhardha.

Hi Naresh,
As of now only directory name (leaf folder) or filename can be used for TP identification in case of File/FTP (except EDI). If your use case does not allow any of these, then please file an enhancement request with support.

Anuj

Second Drive w/ Multiple Permission Issues

Set Up
- PowerMac G5 running OS X 10.5 (client, not server) on primary drive
- 2nd drive where all of our shared files are located (this drive and it's directories are not shared - at least not from System Preference > Sharing - we tried that and the problems still existed)
There are three of us in our office. We all are connected to an Airport network (we are wireless, the G5 is wired to the Airport). We have one man outside of the office who connects to the G5 via FTP. Everyone (internal & external) works with the files on the 2nd drive. Internally, we're all logged in as admins (individual accounts) when we work off the G5.
Problem #1 - when our outside man connects to the G5 via FTP, any files he creates/modifies end up with their permissions set to the following:
Outside User - Read/Write
(unknown) - Read Only
everyone - No Access
The only way to fix it is for someone to log on to the G5 and reset the permissions.
Problem #2 - Inside the office, we're frequently finding files that have not been modified by our Outside User but their permissions are fouled up. A simple example:
I create a directory on the G5, then add some files to it. No one else can access these files or the directory I created. The permissions end up looking like they do for our Outside User who is using FTP except the everyone user as Read Only access.
There's a lot of other permissions related weirdness that is going on. The bottom line is - how should we set things up so we can all use the 2nd drive? In the past (when there were just 2 of us) we both logged into the G5 using the same admin account - no issues ever came up even though we were both logged in all day long.
Should we all share the same admin account?
What about our FTP user?
I'm sure there are some good tutorials but I don't know where to look.
Also, would it be better if we were running OS 10.5 server?
Thanks for any help.

Please help me where am I wrong?
Thanks

I would guess the error happens at this line:
} while(!(Character.isDigit(reply.charAt(0)) && ...
because apparently reply.length() is 0 at the point of failure, so charAt(0) is beyond the end of the string. You need to check the length first.

Using SFTP with FTP Adapter: The SSH API threw an exception.

Our SOA suite veriosn is 10.1.3.4.
We have to get the file from SFTP server and put it on the SOA Server. (SFTP and SOA server are running in different machine)
If Incoming file and outgoing file directory is located in SFTP server..GET and PUT operations works fine.
but if I give Incoming File location = <SFTP location>... and Outgoing file location = <SOA server location>... I get the below error...

Hi,
Thanks for the reply.
As per client's requirement, we shouldn't be using java service for this functionality.
And as you said, the oracle adapters are not taking anywhere, but guess have no other choice..
Cheers,
