File Adapter Polling issue(Is there critical value of File size )?

Hi
I use File adapter as the Activation to initialize a BPEL process instance .The source data is a kind of Delimited file format.On my PC, when the file size is less than 4M ,everything works fine ,But when the size increased. The BPEL process will not initialize the instance.When the source data is XML data , the "critical value " is about 12M. The error msg is below.

how can i solve this problem?can i predeploy some parameter? Is there some critical value of File size for the processing of File Adapter ?

Hi,
There is no specific parameters to specify the maximum file size to be read in. It is just limited by the heap size of the JVM running the BPEL engine.
If you have enough RAM on your machine you can change the current heap size from 512Mbyte to 1Go by editing the startorabpel.bat file
and modifying the line :
set MEM_ARGS=-Xms512m -Xmx512m -Xmn300m -XX:MaxPermSize=80m
to
set MEM_ARGS=-Xms512m -Xmx1024m -Xmn300m -XX:MaxPermSize=80m
But only do it if you have at least 1.5 Gb of RAM on your machine, otherwise ot will keep spawing and you will have very bad performance.
Speaking about performance, do you really need to have a BPEL payload of 4 to 12 Mb ?
Will the BPEL process really need to access it ? if so, the best solution would be using batching techniques to cut you file in pieces and process it piece by peice.

Weird problem in File Adapter polling

Hi Guys,
My BPEL process is working fine not until today wherein the File Adapter cannot poll for new files in the target directory. I tried restarting the bpel server and still my bpel process was not able to poll for new files. I tried creating a test bpel process and configure the file adapter (see below):
Operation Type: Read
Archive processed files: Enable
Delete files after successfule: Enable
Include files with pattern: *.csv
Publish messages in batches of: 1000
Polling frequency: 5 seconds
Minimum file age: 0 seconds
Sample File: test.csv
12345,12345,12345
When I tried testing it, the file was deleted but it was not able to archive the file and bpel process did not appear in the instance tab of BPEL console. I have check the domain.log and orabpel.log files and it didn't show any exceptions or error (log level is set to error)
Any idea how to fix this problem?
FYI, I'm using the version 10.1.3.1.
thanks,

What does your process do other than poll files, does it call any other adapter / service. This is more likely the issue although I have seen issues with the file and ftp adapter in 10.1.3.3 and 10.1.3.1. I never sorted the issue it just seemed to affect that process.
10.1.3.1 is really out of date and has a number of issues you should look at upgrading to 10.1.3.4 or 10.1.3.5 but I have seen some posts that have issues with 10.1.3.5.

File Adapter polls all the files from the directory when deployed again

Hi,
File Adapter polls all the files from the inbound directory irrespective of the timestamp when deployed again.
For ex. when the BPEL process with file adapter is deployed, it starts polling the directory based on the timestamp as and when the directory is written with the files. I did not opt for deleting the files after read by the File Adapter.
But, when BPEL process is modified and deployed again, this time, the file adapter picks up all the files in the inbound directory and doesn't consider the timestamp.
My guess is that it should not pick all the files but based on timestamp only.
I guess I can observe the same behavior if I bounce the Application Server also
Do I have an option to achieve this?
Thanks,
Sasi Bhushan.

try this:
1- create a File object for the directory. (look at isDirectory() )
2- create a File[] that represents the files in that directory. (.listFiles())
3- if (file[x].isDirectory()) {recursive method call;}
4- else {
process file;
If you want more help--do some work on it, and come back with specific questions relating to specific lines in your code and specific error messages you've been receiving.

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.

OSB DB Adapter Polling Issue

Hello Everybody,
Requirement
I am doing DB Adapter polling in OSB.I have a db adapter which polls order table whenever there is a record with status='N'.The OSB component is on single node of Weblogic Server.
1.The db adapter picks the order data with status='N' in the proxy service
2.It transforms to webservice xsd
3.Invokes a webservice.
4.The webservice returns acknowledgement number.
5.The order table should be updated with status 'Z' and attribute1=acknowledgement number
OSB Service Design
1.Proxy service calls business service to poll the order table
2.Converts the payload to the xsd format required by target
3.Invokes the webservice on target
4.Receives acknowledgement number
5.calls a plsql procedure which updates all the records within this batch with the acknowledgement number and status='Z'
My configurations in db adapter
Logical delete option in db adapter.
Unread Value :'N'
Read Value : 'A'
Polling frequency : 300 seconds
no of databse rows per XML document : 10
Database rows per transaction : 10
Issue
1.My process after getting the acknowledgement number it updates the status with Z and attribute1=acknowledgement number.At the of this transaction I am seeing that the status is being updated by
the adapter to 'A' based on read value.I want the read value only to be updated initially but as soon as my OSB process picks it for further processing it should not update again.How can i prevent
the status from getting updated to 'A'.
2.I have 40 records in order table.Per the database rows per transaction it should process 10 records at a time and for each batch of 10 i should get one acknowledgement number.Instead i see that
all the 40 records are updated with the same acknowledgement number.Kindly help as to how I can resolve this situation.
Thanks & Regards,
Radha

File adapter polling frequency is not consistent in SOA 10g!

Friends,
I have used file adapter for polling files in a service in SOA 10G env. with polling frequency 3600 secs. However, i have noticed file polling is not happening at 60 mins interval, instead some times files getting polled in less than 30 mins but again after sometime its polling correctly in 60 mins interval. I am not sure what could be the reason but i need a solution urgently. Please help!

Could be the managed servers in the cluster are not in sync.
I faced DB JCA adapter sync issues because of Oracle soa suite bug.
You could check whether any sync issues are there with File adapters.

File adapter polls before the processing is finished in R3

Hi,
Polling in sender file adapter is set as 4 secs. The problem arises when more than one files with same Service Order number are uploaded and the corresponding IDOCs are simultaneously received in R3 system. As one IDOC is already processing the Service Order, the other IDOC fails as the Service Order is already being processed.
Kindly suggest if there is a way to resolve this issue.

File Adapter: FTP issue

Hello,
There is a problem with the file adapter of the XI30 SP14:
It is set to get a file from a server X using a FTP protocol.
INT_001_V01_COM_CTDCLNT600_FILE_SENDER
Sender Adapter v2300 for Party '', Service 'CTDCLNT600':

- 2006-01-16 15:22:54 EST: Processing finished successfully
It seems everything is working fine, but the in the SXMB_MONI transaction, no message appears.
I have accessed the FTP manually and I have downloaded the file, so the connectivity issue is descarted.
Any suggestion.
Jesus Barba Lobaton

Hello all,
The current configuration of the Sender file adapter is:
Transfer protocol: FTP
Message protocol: File Content Conversion
Adapter Engine: Integration Server
Source Directory: /out
File: D_P.DAT
In FTP: the file D_P.DAT is placed under /out directory
Server: Server Internal IP
Port: 21
Connection security: None
User: userX
Pass: FTPuserX
Quality of Service: Exactly once
Poll Intervals: 60
Processing mode: Delete
File Type: Binary
How can I verify a log of the processing process? as the SXMB_MONI transaction does not show anything.
The most frustrating of all, is no error message appears. I have verified the XI, APPS and default trace logs with log viewer but there is nothing.
I have also checked this thread but none of the solution provide solved the issue

File adapter Deployment issue

Hi,
I have a process that use a file adapter which polles a certain directory.
I am developing on windows XP and I am deploying to a Linux
I can't leave the path of this directory as it is since it will not be recognized in the linux server
How do I solve this issue?
Amit

You can specify the Logical Name of the directory from which you want to read the file from. In the BPEL partner link of the bpel.xml file, you then provide the physical parameter value for the Logical Name. This resolves the mapping between the logical directory name and actual physical directory name.
For example you can specify Logical Name as InputFileDir and in the bpel.xml specify the physical value against the partner link for that file adapter, as following :
<property name="InputFileDir">C:/ora_home/integration/bpm/samples/tutorials/
121.FileAdapter/ComplexStructure/InputDir/</property>
So while development, you can specify the physical directory as in your Windows system, and at deployment you can specify the directory as in your linux system.

SOA Suite and File Adapter polling

Hi All.
Whenever I have a BPEL process deployed (didn't test whith ESB yet) that uses a file adapter tha polls for files in a directory, my SOA Suite is not able to shutdown properly, and it stops with error when it's time to stop the container that has the BPEL installed.
This is the error message:
There are some errors while stopping the following components. Refer to the generated error report for more details.
==================================================
ias-component: default_group
process-type: oc4j_soa
process-set: default_group
Error Message:time out while waiting for a managed process to stop
==================================================
Looking at OPMN log, I see that the managed process was forcefully shutdown.
Is this an issue, or a normal behavior, or do I have to implement some code in order to stop the BPEL process before shutdown?
I'm using SOA Suite 10.1.3.1 in a developer environment (Win XP)
Regards.
Denis

I applied patch 5964097 (OPMN PERFORMS ALWAYS A FORCEFUL SHUTDOWN IN 10.1.3.1) and it seems to solve the problem, at least for the BPEL scenario explained.

XI adapter polling issue & JDBC / DB2 driver connection timeout properties

Hello Group,
We have a long running issue with our XI 7.0 system running on iseries. (V5R3) The issue occuring is that our XI adapters stop polling and the only resolution is to restart the J2EE engine or to resart the adapter framework services.
We have had several OSS messages open on this subject for over a year and are going round in circles with the a number of different SAP consultants.
The one topic that we keep coming back to is that we are being asked to set DB2 driver connection timeout properties. We are using the toolbox driver and have upated to the latest JTopen driver, but have not managed to find any inofrmation on how to set the timeout parameter. Does anyone know where the timeout parameter set?
Has anyone experienced polling issue like this before and how did you resolve?
SAP referred to the SAP note 1078420 - XI/PI JDBC Adapter: Setting JDBC driver properties for DB which is for Oracle, but this will give an idea of what timeout parameters SAP are asking about.
Extract of the note is below:-
Symptom
This note gives an option to set JDBC driver properties while acquiring a DB connection. When connecting to DB using JDBC adapter there are instances
where DB connection take a long time to establish connection. Some times call made to Driver will hang permanently. Setting driver properties would resolve this problem.
More Terms
Connection timeout, time out, query timeout
Cause and Prerequisites
Solution
In the advanced mode table section of sender channel and receiver channel configurations, we can set driver properties for each DB connection. Any
such property would have to contain prefix 'driver:'(with out quotes) For example, for Oracle Database JDBC thin driver 10.2.0.3 version, the
property oracle.jdbc.ReadTimeout helps to set read timeout while reading from the socket. Also for setting login time out in Oracle, we use
oracle.net.CONNECT_TIMEOUT. To set these two properties use as follows:
driver:oracle.jdbc.ReadTimeout 1000
driver:oracle.net.CONNECT_TIMEOUT 1000
(The TimeOut Driver properties like ReadTimeout and CONNECT_TIMEOUT are in milliseconds)
Refer to your DB documentation/ JDBC driver documentation on this. Please note that properties can vary from each driver version. For instance, some
of properties of Oracle JDBC thin Driver 10.2.0.3 properties may not be present in older version drivers. Please contact DB vendor for the complete
list of driver properties. In addition to above, we also provide another parameter for query time out.
sqlquerytimeout (prefix 'driver:' is not required) is the parameter that is to be used for SQL query time out. This is case-sensitive and should be
configured as positive integer value in seconds(greater than 0).
Any help on this would be much appreciated.
With regards,
Steven

Hello,
I am not talking about the XI timeouts. But the timeouts which can be used to get the connection timeouts for DB2/AS400 databases.
So please provide that information.
THanks,
soorya

DB adapter polling issue-urgent

Hi ,
I am trying to poll for new or changed records from DB table using a DB adapter. I used a DB adapter with Poll for new or changed records in a table operation type and used a bpel process to write the changed records in a file adapter(using write file oeration). whenever i update a record or insert a new record it is not polling the chnaged record and instance is not getting created for the composite.

Sometimes the messages get rejected if they are not compliant with schema even before coming to the SCA Infrastructure, the rejected messages for the database adapter will be stored in the following location....
Let's say if your composite name is TestDBPolling, and if the messages for that composite are rejected, they will be stored under the following location...
C:\Oracle\Middleware\home_11gPS2\user_projects\domains\domain1\rejmsgs\soa_server1\TestDBPolling
This is on my local machine...
Let me know whether that helped you...

XI file adapter polling faster than poll interval

Hi,
We are facing a issue with the file adapter/authorization of the FTPUSER.
We FTP a server and pick up a file from a particular folder.
My polling interval is 2 minutes
My retry interval is space.
Processing mode : ARCHIVE
We are archiving it on a Network attached server(NAS) mounted on our XI server.
When XI polls for the first time it picks up the file but the sender file adapter shows following error in RWB.
2006-01-20 11:31:08 GMT: Error: Deleting of file 'ARUCSjnewb80.txt' failed - cannot proceed: FTPEx: ARUCSjnewb80.txt: Access is denied.
The picked up file gets processed but at the same time just within 12-13 seconds of the first poll XI picks up the file second time and then in another 3 seconds for the third time.
After this the file gets archived thrice in the archive directory and then gets deleted from the source directory.
We are unable to understand why XI is polling again after few seconds of the first poll.(As per my understanding it should have polled after 2 minutes).
I am able to delete the file manually from the Ftp server.
Could anyone give a pointer towards what we are missing or what probable reasons could be?
authorization issue?( XIADM /ftpuser have full authorization)
Some adapter setting?
Regards,
Sulakshana

Hi,
Could you let me know how frequent the file gets loaded to the FTP server.
Is your file size too large to get loaded.. If so try to increase the polling interval. Also make sure that you have provided the polling time in sec and not in minutes...i.e for 2 minutes it should have been specified as 120 sec as polling interval

File adapter polling and getting the file name 11g Jdeveloper

I am using JDeveloper 11g. My process is something like;
A file adapter reads a XML file
This triggers the BPM process, file content is sent to start activity as message
I have to get the file name that is read by file adapter.
How to do that? Any help is appreciated.
I have seen couple of answers like bellow in forum but did not help me much
This is a very simple task in JDeveloper 11g, file adapters are linked to the receive activity, here there is a tab called Properties which you can use to extract the file name. Please follow the steps below:
1. Create a Simple Type variable of string type, call it fileName_var or any name you wish.
2. Open the Receive activity in your bpel project.
3. Scroll down to jca.file.FileName and double click on the value column, click on the browse button (...), select Variable, then click the search icon
4. Locate your recently created variable
5. Now when your project runs it will assign the file name to this variable, you can use this same approach also to pull the directory, file size, etc.
*************************/

hi,
Like you said.. steps are simple and clearly mentioned in guide.
1. create a variable of type string
2. after configuring the file adapter , go to corresponding receive activity , go to properties tab
3. search for a property with name as jca.file.FileName . This basically keeps track of file name
4. for this property, give the value as name of variable created in step 1 above
5. Use this variable anywhere in assign / transform

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.
