FTP Adapter Read without Polling

Hi,
Can we use FTP Adapter to read the files without polling. My requirement is to read the file from a location only once at a specific time. So I don't want my starting BPEL process to be a Adapter which polls rather I want to internally invoke the Read process without specifying a specfic file name.
The file name is not fixed and so I think Sync Read will not work.
Can we achieve this?
Thanks
Sanjay

Can Scheduler be used in ORACLE SOA to trigger FTP Adapter read operation

I need to create an ESB project where scheduler should trigger the File/FTP Adapter read operation.
Where can I provide the time settings viz. (xx HR: yy MM: zz SS everyday)?
Is it possible in Oracle SOA?
Please provide any tutorial where scheduler has been used to invoke the File/FTP Adapter rather than invoking it real time (gets triggered the moment files are placed).
Thanks

You should the quartz timer within the SOA Suite to obtain this functionality.

ESB- FTP adapter unable to poll a file

I have a FTP adapter it has to poll files, with diff naming convention.(like "asd", 'wer',"jkl","AVC"). But the adapter was unable to poll a file which name start with AVC
reamining files are polled successfully.At ftp location ftp adapter will poll file and place all records into DB through ESB,for ESB we can set adapters as inbound.Plz give me any suggessions to solve this problem(10.1.3.4).Thq.

I checked the error logs and it informed it was not able to create the stage directory where as i am only creating the stage directory and providing the path to it.so i could not really understand the exact error.
Does a stage directory get created automatically anywhere else?

FTP-Adapter reads filled file as empty file

Hi, well i have a FTP-Poll to a folder where a filled file is existing. the adapter takes it and put it into archive folder after saying that the content is transformed into XML (shown in CC-Monitoring).
Well the archive file i found but in Monitor there is no message. So where is the XML file?! actually it should be send to an IDoc-Adapter after content is transfomed! What is the problem??
I have done some other Scenarios like this and they work. I compared all the parameters but nothing seems to be wrong.

FTP Adapter on Unix

Hi There,
I created a new JNDI Location and configured corresponding connection Factories for the above FTP Adapter. In the connection Factories I entered my username and password and unix server host name. I set the the ftpAbsolutepath to my Home Directory on the server.
I created a simple BPEL process which uses FTP Adapter to get a file and inserts into database as a BLOB. The FTP adapter is not polling and file is not getting deleted.
Please Advise.
Thanks
Krishna

Hi Antonis,
Sorry for the confusion. It didn't pick up at all.
I am using FTP as Service Component.
As it is not polling, I initiated it manually from BPEL Console.
Then it is inserting a record into the Database as a blob.
I am not getting an error. I did not understand how it is inserting data into database when it is not getting the file at all.
I then modified the above BPEL Process by adding one more DB Adapter and FTP Adapter. DB Adapter will read the blob and FTP Adapter will write the file back to the server in a different path.
When I initiate this, I am getting the below error:
Unable to send file to server
;nested exception is
ORABPEL- 11429
Error Sending File to FTP Server.
In summary it seems that the process is not hitting the FTP Server.
But as per connection factory setting, username and password is valid and have access to the server.
Could there be any other reason.
Thanks
Krishna

BPEL FTP Adapter problems

Hi!
I have two problem using the FTP Adapter in a BPEL process.
The first can be described as follow: I have a BPEL process that incapsulates the FTP Adapter and it is deployed correctly on the BPEL default domain. It's working fine in a normal context with no error. Now I want to simulate a "read FTP Server" crash; so I put the FTP Server from which I'm reading off-line. When the GET module of the FTP Adapter tries to poll the server, it generates a Null Pointer Exception and on the server command window I can read, after a while, that the process state will be set to OFF. But when I enter in the console I always see the state ON! But the interesting question is: is there an automatic way to recovery the process and to restart it? I see that in the domain parameter there are two values: rcvAgentDelay (7200) and rcvThreshold (600). I tried to set them to some other values, for example (120) and (10), but the process still remains "blocked" and no new polling seems to happen.
The second problem is about the creation and the deploying on a new domain. I create a new domain called "bulk" and I tried to deploy my process on it but I can't do it due to the generation of many exception! Can I deploy a process with a FTP Adapter component inside on a domain different from the default one? And if the response is positive, like I think, can you summarize the most important steps of it and if I must configure some specific domain parameters?
Thanks a lot,
Busnelli.

OK, firstly I want to thank both of you, Rakesh and Maneesh.
Here are the details requested:
Operation System = Windows XP Pro SP2
BPEL Process Manager = 10.1.2
BPEL Server version = 2.2 (build 1361)
JDeveloper version = 10.1.2 (build 1811)
BPEL Designer version = 10.1.2 (build 050322)
Usually after any modification I'm used to restarting the BPEL server.
Today I have downloaded the "Oracle JDeveloper 10g (10.1.3) - Developer Preview" (I think to be the Post Beta 3) and as soon as possible I will try to use it.
Thanks to both!

FTP Adapter - Filename of archived XML File

Hi All,
We are trying to poll Files from Remote Servers using FTP Adapter, after its polled we are keeping the archived file in a directory. Files are archived but its with other name eg: XXXXX.XML is archived as XXXXX.XML_HmuUJDA1qKj2btjp_y1JUeLmgZsJcqhyCnrdlgB6sgU=_20110112_220537_0567.
I want to archive the XML file as it is like XXXXX.XML name only.

Novice Question: XML File using FTP Adapter Help Requested

I need to create (publish) a message from an XML file that is written to a particular folder on a Win2000 machine (I intend running the adapter on the same machine). I think that the FTP adapter should be the easiest way to do this but I have only used this adapter to publish DL3-defined files, and only then on a unix platform.
Is the FTP adapter the correct approach or is there a better way, and if it is the correct approach, can anyone point me to a sample application or pass along a sample adapter.ini so I can figure out configuring the adapter.
Thanks
Eric

We use the FTP adapter for both reading and writing XML files. And it works quite OK (there are a few gliteches but nothing you cannot work around). You need to first make (find) a DTD for your XML file and import that as the AV for the message in IS (IStudio). Then you just point the adapter to the correct directory and it should work from there.
As for better way Im not sure I'm no InterConnect expert but I dont know any other way to do it.
Might be worth to notice (if you didn't already know) that you dont actually need FTP if it is on the local filesystems you can in the FTP adapter read from the local FS something along the lines of file:///c:/foo/bar as oposed to ftp://...
As for adapter.ini you shouldn't need anything besids pointing the reciver to the correct directory the rest is done from IS.
Let me know if you want more details...

FTP Adapter is unable to connect to server

Hi All,
I am using the FTPAdapter in my BPEL process and trying to connect the FTP server which is running in my VMware linux machine. I am able to connect to the FTP server successfully from my windows machine and I am able to get and put the files. But my log says that it's unable to connect to FTP server. I see the following message in domain.log file
+<FTP Adapter::Inbound> Poller raising Alert for exception : ORABPEL-11438+
Error in establishing connection to FTP Server.
Unable to establish connection to server.
Please ensure hostname and port specified to login to the server is correct.
Please help me to connect the FTP server successfully from my BPEL process.
Thank you.

Linux usually has ftp disabled, try using ssh
if you are on 10.1.3.3 this has been enabled.
I would tend to do all my modification in the Enterprise Manger console, not the xml as you are able to get more meaning around the filed names and what they are used for.
To enable ssh you need to perform the following
change the port to 22
set ssh encryption = true
cheers

How to Read a file using File Adapter without polling

In My process I want to be able to read a specific file.
But without polling for files?
Can I use the File Adapter for this?
Thanks
JO

Yes you can.
Read about Synchronous File Reading Capability here download.oracle.com/otndocs/products/bpel/bpeltechadp.pdf
Also read this: Re: Help! Three questions about FileAdapater.

FTP Adapter to read multiple files from a directory. Not through polling.

Dear Friends,
I would like to know is it possible to configure the FTP adapter in Oracle BPEL 10.1.3.4 to read multiple files (different names, same structure) from a given directory. I do not want the BPEL to do a polling. Instead when I submit the BPEL process it should read all files from the directory.
I was looking at the option of Synchronous read but I am not able to specify wild card in the file name field. I do not know the file names at the time of reading.
Thanks for your help!

Hi,
While you read the file, you can configure an adapter property in 'Receive'. This will store the filename, this filename can be used for sync read as the input parameter.
1. Create a message type variable called 'fileheader'. This should be of type Inboundheader_msg (whatever relevant Receive activity).
2. This variable will contain three parts - filename, FTPhost, FTPPort
3. Copy this fileheader to 'Syncheader'.
4. syncheader can be passed as an adapter proerty during sync read of the file.
During Receive and Invoke, you need to navigate to 'Adapter' tab to choose the created message type variable.
Let me know if you have further questions.
regards,
Rev

File Polling is not working in FTP adapter

Experts,
Configured FTP adapter should poll the file from the FTP server which is in active mode .But this is not happening as expected. This feature was not available in Oracle soa 10g
http://download.oracle.com/technology/tech/soa/soa_best_practices_1013x_drop3.pdf
they say :
Does the FTP Adapter Support the ACTIVE Mode of Connections?
No, for security concerns the FTP adapter supports PASV (passive) only.
Do they have not change this feature in Oracle soa 11g.
Your thoughts will be very much appreciated.
Thanks

I doubt if the ftp path is not given correctly. Can you try this.
1. if you gave logical_file_path try giving the actual file path or vice versa and try.
2. having the highest level of logging enabled (development). You should see some error in the logs. Is this on linux or windows, if linux search is case sensitive
hence search for 'rror' without 'e' as you donot know the case it would be in.
3. last option try retiring the process and then turn it on. This works sometimes to pick the file

FTP Adapter to poll multiple files (different formats)

Hi,
We have a requirement to poll and process multiple files from a given FTP location(either process all or reject all - reject if there is any failure in one of the files).
Using FTP Adapter's Get File operation(Schema Opaque), we are able to read three different file formats and can get the file name(Using header variable FileName).
And we are hoping to process the file contents based on the File Name that we get from the above step.
1) How do we convert the file contents from Opaque to specific Schema (ex: file1.csv, file2.csv and file3.csv with different formats)?
2) As the requirement is to process all the files at the same time, Can we use correlation in the poller process to route to single controller process(One instance of Controller process for all the files)?
Any help would be much appreciated.
Thanks...

Thanks a lot for the quick answers.
I've used the Java embed to convert Base64 content to String. And using 'translateFromNative' extension, I could convert it to the desired XML content.
But I still have trouble in polling and processing all the files(file1.csv, file2.csv and file3.csv) at the same time using a single controller process.
My requirement is to process all the three files at the same time(for any failures I have to compensate any/all of inserted records).
I tried using Pick(with different OnMessage branches), but as they are polling the same location I could see only one OnMessage branch is getting fired resulting in multiple instances.
May be I didn't understand your suggestion correctly, could you please elaborate on the possibility of processing multiple files at the same time?
Thanks

Problem while reading multiple files through FTP Adapter

Hi,
We have a requirement to read the excel files placed in an FTP Location and as there is no Adapter to read Excel file
we are using FTP Adapter and reading the Header values of the file(name of the
file) and we are paasing as input to the Java code which will read the data nd insert into the Database.
If we place above 20 files it was reading only some files and some were left and if we delete the files and place the unread files again some files are read and if we do the same procedure then all the files were read.
Any help regaring this appreciated.
Thanks and Regards,
Nagaraju .D

Are you doing anything complex for your polling, e.g. Files that must be n time old.
Can you post the WSDL so I can see the polling configuration. I only need to see the adapter configuration, not the whole file.
cheers
