OSB File Transport Polling Interval

HI,
I need to know can i set File Polling Interval in milliseconds in OSB 11g. By default is in Seconds....
http://docs.oracle.com/cd/E14571_01/doc.1111/e15867/proxy_services.htm#i1276922
i have found a link which says we can set in milliseconds also but that is in 10g
http://docs.oracle.com/cd/E13159_01/osb/docs10gr3/httppollertransport/transports.html#wp1076007
So please let me know how to set polling interval in milliseconds !!

Abhinav,
SLA of just a second is too short when it involves reading a file and calling a web-service as well. Here the size of file and load may also cause delay, even there is possibility that OSB may read half written files. Anyways, file an enhancement request with support and let OSB Product Development review your requirements. If found feasible and valid then you should get this functionality as a patch.
As a workaround, you may consider using a java utility to poll the file and invoke OSB service though it's not an attractive solution and you may face issue of reading half-written/incomplete files. I would consider reviewing the solution design here.

OSB Email Transport polling in multi cluster environment

Hi,
I have following scenario: email needs to be read by OSB proxy using the Email transport. The proxy service service will poll the IMAP mail box and processes messages, upon reading a message message is deleted.
The email transport works fine in a cluster environment by using a dedicated managed node for polling, so no duplicate messages will occur.
However, we have two clusters in our environment pointing to one mailbox. In this case, two clusters have no visibility of each other. So, two pollers may poll the same mailbox.
Please, advice if there any configuration on OSB, Weblogic or IMAP can be done to solve this issue.
thanks,
Djail

Dont think it will work in an Active-Active setup. If you have both clusters listening to same email address then both will receive a copy (just like you receive same email on your desktop's email client and also on your mobile's email client) because SMTP servers distribute to clients similar to how a JMS Topic works.
Dont know if there is a setup in IMAP which will allow an email to be sent to only one client (in this case one of the OSB clusters).
If you want to make it work in Active-Active then you will need to do it at functional level, for ex. after receiving an email if you have any unique id then log that in a transaction table, before calling the backend, check if the same email was already processed by the other cluster. Alternatively, check at the backend before processing it.

OSB File Transport Configuratuin - File Mask

hello, im intrested with collecting spasific type of File - such as *.doc *.pdf *.txt etc.
but not_ all as defult in File Mask - *.*
Does anybody know how to set OSB proxy to collect multi type of spasific files
this Form Q didnt solve the issue:
Re: Regular expressions for file/FTP transport within OSB. How?
and this artical explain that its a Regular expressions ( a mistake..)

Yes see my post on this a week or so ago. They don't support the full Regex expressions, just simplified (Unix file name style).
The answer is to "chain" your proxies, having say two file pollers matching simple patterns (e.g. one with *.doc and one with *.pdf) and then feed these to a common proxy using the local transport.
Alternatively, if you want to process all files in some way have a single proxy matching all the files and then use an XQuery matches function to match the regular expressions against the filename and split the processing from there.

Polling interval in file adapter.

Hi,
I have a doubt regarding the file adapter polling interval.
Suppose we get a file of size 512 MB and PI file adapter taking long time (say 15 Min) to process it, we have a polling interval of 10 min.
I have a 2 doubt in this case.
1. what will happen in the next polling interval. because the older file still is in process and it is still in the source folder location.
2. if at the same time there is new file get places in same folder location. then how the file adapter behave in this case. Is it start picking the second file or again poll the incomplete file.
I want to know that is PI maintaining some lock while processing some file from source folder.
regards,
Navneet

Hi,
I guess normally it should process both files, earlier one which is in process and the new one as well (it depends your selection string in file name scheme).
Also refer thsi Wiki to help in avoiding duplicate file processing:

How to increase the files picked up by File Adaptor per poll interval

Hi,
We have a scenario where in we post 80 files in the source directory and and the file adapter is configured for every 300 sec but i have noticed that the File adaptor is picking up one or two files per poll interval.Can some please suggest how to increase the number of files picked up by File adaptor
Thank You,
Nandini

Nandini:
Did you mention all the files names in the Adapter channel. One thing you can do is use wild cards and file adapter picks most of them
/people/mickael.huchet/blog/2006/09/18/xipi-how-to-exclude-files-in-a-sender-file-adapter
In case if your files are huge, then I guess file size may cause to process few files during each poll

Maximum Polling Interval in File Adapter

Hi,
Can you please let me know what can we set as the maximum polling interval in the Sender File adapter?
I have a scenario where I am setting the File Adapter polling interval as 7884000 secs. i.e.2190 hr= approx 3 months.
But the file adapter is polling at very short intervals.
Any help on this would be appreciated.
Regards,
Sampada

You need to configure the polling settings so that the system does not become overloaded, but at the same time, in a way that end users do not notice a major decrease in performance over time. Keep in mind that the greater the polling interval, the less frequently users will receive updates.

Specify filename in OSB File Trasport Business Service

Hi All,
Is it possible to specify the complete filename in OSB File Transport Business Service?
the default behavior allows me to specify the prefix and suffix only, is it possible to override and specify the complete filename?
Thanks,
Tal

Oracle Service Bus: Concurrency using File Transport Provider?

We're using the OSB File Transport Provider but we're not able to process files concurrently.
Each time processing of a file is started - processing of other files (in the stage directory) halts.
Does anyone know if this is a "feature", or are we missing out on some configuration?

Do you have a clustered environment? What is the load? You may like to create a separate work-manager for your File proxy and assign appropriate number of threads to it.

Defining polling interval on customization file

Hello everyone,
I have a requirement: define a polling interval (in this specific case for a email polling proxy, however it would be useful for a file polling proxy as well) in a customization file.
It seems a simple task, however i could not find a way to perform...
I've searched here in the forums and have found nothing (if someone finds a thread about this please provide the link).
I've googled a bit as well, and the result was the same...
In this blog post http://wesselj.blogspot.pt/2012/01/oracle-service-bus-good-bad-and-ugly.html we can read:
"+(...) Customization files. Inflexible, verbous and complex to maintain. Not everything can be customized with the customization files, some like passwords are reasonable, *but things like polling interval for file integration would be nice to be able to change between environments*.+"
And in this document http://docs.oracle.com/cd/E11036_01/alsb30/pdf/consolehelp.pdf , in the customization topic (page 29-1), there is nothing mentioning polling interval...
The environment installed is OSB 11gR1.
Any suggestions on how to perform this task?

Any ideas?

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.
<b>2006-01-20 11:31:08 GMT: Error: Deleting of file 'ARUCSjnewb80.txt' failed - cannot proceed: FTPEx: ARUCSjnewb80.txt: Access is denied.</b>
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

Sender File Adapter always "Polling interval started" without complete

Hi,
I have problem with sender file adapter suddenlty the status from Communication Channel Log monitoring always with polling started without completed.
4/25/11 11:40:33 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:40:23 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:40:13 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:40:03 AM   Polling interval started. Length: 10.0 seconds
Normal :
4/25/11 11:41:50 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:41:50 AM   Processing finished successfully
4/25/11 11:41:50 AM   Processing started
4/25/11 11:41:40 AM   Polling interval started. Length: 10.0 seconds
4/25/11 11:41:40 AM   Processing finished successfully
4/25/11 11:41:40 AM   Processing started
I have tried to stop and start the channel but still no luck. This problem only happen for this particular communication channel others channel is working fine.
Please advise other solution before i need to restart the java engine since this in the production environment. The problem is some of the process was delayed because this issue. CC was delayed to pickup the file.
Thank You in advance.

Hi Abhistek,
Thank you for your correction. It was typo.
Which assumption is correct ?
1. All 3 instance running together in the same time ? or
2. Either 1 of the instance running once time manage by clustering setting.
Example :
15:01:00   ---> A
15:02:00 -
> A
15:03:00 -
> B
15:04:00   -
> B
Currently :
15:01:00   -
> A
15:01:00   -
> B (lock)
15:02:00 -
> A
15:02:00 -
> B (lock)
It seems all 3 instance lose control from clustering ?

Sender File Adapter - Restrict number of file polled at each poll interval

Hi all,
PI 7.0 SPS16.
We would like to know whether it is possible to configure a sender file adapter (file conversion mode) in order to restrain the number of file taken at each poll interval and if yes how ?
Thanks for your future answers.
Jean-Charles

Hi Jean
Standard adapter do not provide functionality to take an input like number of files to be taken at poll interval. But using adapter module you can achieve this.
SAP PI is having the function to set poll timings and scheduling. You can write adapter module and execute this module using File adapter type communication channel before the standard bean and you can restrict the number of files.
Check the link given above as well as this How to Guide
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/3bdc14e1-0901-0010-b5a9-a01e29d75a6a

Poll interval for sender file adapter.

I have a 1_sender file NFS file adapter which picks a trigger file from X location in PI application server, this trigger file initiates the unix script present in the sender file adapter.
Unix script brings all the file which starts with 25588* from bank FTP and places in Y location in PI application server then script deletes the "trigger file".
another NFS File adapter 1_receiver file adapter places the trigger file in the X location of PI.
for 1_sender file poll interval given as 86400, that means it should trigger only once a day @ 1:30pm.
But today same sender file adapter had triggered 4 times, could any one let me know the reason why it had triggered 4 times instead of single time.

Vidya,
There are two things :-
1. The polling interval should be 24 hrs;
2. The polling interval should be 24 hrs and it should poll at 1:30 pm every day.
For any reason if the channel is re-started, then with your present configuration, you will never be able to achieve # 2.
So, better use ATP.
But today same sender file adapter had triggered 4 times, could any one let me know the reason why it had triggered 4 times instead of single time.
Might be the connection dropped / failed at the time of polling and the channel re-tried. If you give more details (what time and with how much interval it triggered), someone might be able to help.

Neetesh

File adapter not reading (not starting polling interval)

Hello,
I've got one communication channel trying to read a file each 10 seconds.
The file adapter is configured correctly and the channel is started but sometimes it stops the polling interval process and I don't know why.
For example the channel was working fine until Friday but with no reason it stopped to attempt to read the file on the directory... what can it be?
And another question. What's the difference about communication channel with "Automatic control" or "Started" manually?

Hi,
And another question. What's the difference about communication channel with "Automatic control" or "Started" manually?
Whenever you create new communication channel in Integration directory and activate it,its status in control data is Automatically and whenever you change it in RWB (Stop/Start) its status changes to Mannually.
Thanks!

OSB File polling working twice with the same file

I have a problem executing a proxy service that get files from a file system. Everything in the flow works as expected, but at a certain point I must wait an update on a database and the process awaits for that change. Everthing goes normal if the update comes within the next 1-7 minutes, but after that if the process is still there(generally 9-11 minutes), a second process is called and the file processed is the same. After the first process is called the folder is empty so I can not understand why the proxy is called again with the same file, since there is nothing on the folder. This can happen since I am doing database modifications.
The process is only invoked twice with the same file, no process is called again(A Third one) if the two processes are still working, wich is weird. since nothing in my proxy logic returns to the beginning.
Does "Weblogic/OSB" tends to free resources on a specified time, such as "Max Stuck Thread Time" but for files or other resources?
Any ideas why this is happening
Thanks in advance.

I think this is due to transaction timeout. The PolledMessageListenerMDBEJB under File Transport provider has a transaction timeout of 10 minutes. So if you are having a very long running transactions which spans more than the 10 minutes, you might see the rollback happening due to timeout.
To confirm is this is the case, when this issue occurs, Go to JMS Modules >jmsResources >wlsb.internal.transport.task.queue.file_auto_n >Monitoring. You should see messages in messages pending column.
click Show Messages. Click on a message and check Delivery count. This should have a value 1 or more which should mean message has been rolled back atleast once before.
if it is the case you can try modifying the transaction timeout value of PolledMessageListenerMDBEJB under File Transport provider in deployments and then update the file transport provider deployment. Parallely check with support on what is the official recommendation for increasing timeout.
