OSB File append

I have setup a File protocol based Business Service in OSB. This Business Service is called by a Proxy Service after setting the file name in the outbound transport header and assigning the text to be written to the file. When executed, the file is successfully created. When the proxy service is executed again, a new file is created. I would like the data to be appended to the existing file. How do we achieve this?
I know there is a property - 'Append' which should be set to true in case of file adapters. I tried setting the outbound transport header to 'Append', 'append', 'jca.file.append', 'jca.file.Append'. None of these seem to help.

Thanks for the link. That really helped!
However, though the file is created by the file adapter, the contents are missing. While configuring the File Adapter in JDev, I defined the following XSD as the message for the write operation.
<xsd:element name="log">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="logMessage" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
And I am sending the following in the SOAP Request...
<log:log xmlns:log="http://myNS/LogFileWriter">
<log:logMessage>My Log message...</log:logMessage>
</log:log>
I expect the value 'My Log message...' to be written to the file. However, it is always empty.

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

Specifying the filename for outbound FTP transport in OSB the thread discusses with FTP BS and same would apply for File BS

ODI - IKM SQL to File Append - Header not Generated

I'm using ODI IKM SQL to File Append to create a text file, but the header is not being generated. And the GENERATE_HEADER is set to Yes. The file is Tab delimited and the Heading (number of lines) is set to 1.
Seems to only be an issue with HFM files coming from the Unix server.
Any suggestions?
Thanks, Mike

File append

Hi !
I have a file log.txt. I want to add data to this file at the begenning without deleting the previously present data in log.txt.
How can I do this ?

Append to the end of this file:
boolean append = true;
FileOutputStream out = new FileOutputStream(file, append);The data isn't added to the beginning of the file, you say? Look at the file from a different point of view, says I.
And if you are logging, there are better ways to do it: {color:orange}http://logging.apache.org/log4j/1.2/index.html{color}

Log4j file appender

Hi,
I am using log4j for logging. I am working on a huge application and there would be lots of logs each day. Thereby it is requried that the log files be stored and renamed each day. The date is appended to the log file and that day's log file is stored. The logs start writing afresh each day. The problem here is that at times the application simply starts logging to the previous day's log file, for a while, and then starts writing back to the current day's file again. I am not able to figure out what goes wrong and when. The application is running on weblogic. Can anybody please help? The log4j properties file is here....

I found from the log4j 1.3 API javadoc, the DailyRollingFileAppender is deprecated. They use the RollingFileAppender instead and give one sample .

Log4j Logger and File appender

I have a problem with my logger file. It look like this :
# appender "file" writes to a file
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=src/logs/test.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
log4j.appender.file.threshold=DEBUG
The problem is when I write to the logfile test.log. The contents of the previous "run" is still there. What I want to achieve, is whenever I run my application, only the content of that "run" should be present on the logfile.
What to add ?
Cheers !

It works fine now. I only had to add the line :
log4j.appender.file.append=false
so now it look like :
# appender "file" writes to a file
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=src/logs/babel.log
log4j.appender.file.append=false

OSB file logging settings configuration

Dear Experts,
I need to know if it is possible to log on file all messages of error (i.e $fault variable) during a flow execution without using in the flow neither logs neither report. Is it possible ? If it is, which the correct WLS settings configuration ?
Regards,
Mike

I can only think of one solution: using the debugging/tracing facilities of OSB. You could enable execution tracing for a particular proxy service, or you could enable debugging of pipelines in the alsbdebug.xml file in your domain's home. For this WLS's log should have a severity level of debug. Of course this would mean you'd have a lot more messages in the log files, not just the errors. I would not recommend this for a production environment.
Why can't you use the Log action that's specially designed for sending messages to WLS's log file?

How To Control The Archive File Name using file adpater or OSB file traspor

Hi all,
My requirement is I want to archive a file by appending my BPEL instant id to the file name.
Is this possible changing the file name when archive the file???
Thanks
Phani

I couldn't find that out when I had the same requirement. I was running out of time, so I let Archive functionality works as it works and used the write file option with opaque schema.

OSB file Write, not naming the file with specific name.

Hi ALL,
I have a requirement, i should accept the data or XML file from from JMs queue and place it in a location specified. For this i have build the PS and BS.
Where PS will De-queue the JMS queue and route using Service call out to BS. And the BS will place the file in location. I could do this easily. BUT the thing is that i could not name the file perfectly with the intended file name. to build the BS i used .JCA file , .WSDL file, XML file from Jdeveloper. and imported to osb console. i could write the file as follows..
MY business Services:

OSB File Proxy Error Handling

Hi,
I've encountered a strange behaviour in my proxy service.
Legend:
FPS -> File-based Proxy Service, reads files from a local directory
EH -> ErrorHandler of the FPS
JBS -> JMS-based Business Service, writes to a JMS Queue
Scenario: FPS reads files and calls JBS to put messages in a queue
Problem:
When testing my FPS, when there is an error (for example in the Service Callout to the JBS) I noticed that the system instanciates a new Proxy Service to "retry" the same file. I also noticed that if I place a Reply Action in the of my EH, this retry mechanism doesn't happen.
What I gather from this is that the file adaptor is somehow transactional, retrying the process (only once) in the event of an error.
Question:
Is this the normal behaviour for a file adaptor? If so, how can I configure the number of retries?
Thanks,
Adel

As mentioned before, in the tests I executed I noticed that when there's an error, the system automatically retries the file by creating a new instance of the same Proxy Service.I'm little confused what type of errors you are talking. Under the hood MDB is used (that is the reason you see JMS queues wlsb.internal.transport.task.queue.ftp,wlsb.internal.transport.task.queue.file). Based on you error you can easily figure out what might be the cause. I suspect that to be effect of redelivery-limit=1.
eg in xbusResources-jms.xml in your domain config
<queue name="wlsb.internal.transport.task.queue.file">
<sub-deployment-name>wlsbJMSServer</sub-deployment-name>
<delivery-failure-params>
<redelivery-limit>1</redelivery-limit>
</delivery-failure-params>
<jndi-name>wlsb.internal.transport.task.queue.file</jndi-name>
</queue>
So, what's I'm trying to figure out is if this behaviour is normal? Is this the way OSB implements retry at the Proxy Service level when it's configured with a file-adaptor?Same behavior will also be in FTP/SFTP as with File
Thanks

In OSB file protocol, trying to get the archived file name in proxy service

Hi,
I have a requirement that i need to process the archived file of file protocol, with java callout in proxy service.
I am able to get the file name which is reading with 'tokenize($inbound/ctx:transport/ctx:request/tp:headers/file:fileName,"\\")[last()]' , but this file is getting archived to archive folder. I want to pass the archive file name as input to the Java callout.
Please let me know if this can achieve in OSB proxy or any other options.
Note : I am reading a xlsx file in the file protocol

If you're using pass by reference option in the file transport, I guess the archive filename can be obtained from $body/ctx:binary-content/@ref. Try it out.

Reading in a txt file, appending numbers to it.

So I'm a student at Georgia Tech working on a relatively simple Java program for a research internship, but it's been awhile since I've had my Java course and I'd really like some help on this. Basically, what I'm looking to do is to take in a text file with data that only consists of the numbers 1,2,4 and 5, with up to four digits in each line and no number may be repeat itself in the same line. A sample of data would look like the following:
12
21
154
2
1
45
24
4125
Lines like '12' and '21' would count as the same however, as would '4512' to '1245'. I'm trying to determine how often each number 'interacts' with each other number, and then append that data to the end of the text file by saying something along the lines of:
One-Two Interactions = 4
Four-Five Interactions = 6
Etc. etc. The real problem I'm having is I can't remember how to get the BufferedReader to 'identify' the particular numbers and combinations of numbers before adding to the count in each variable. If you have any advice or answers, it would be greatly appreciated.

Multiple flat files appended, is file locked until all processed?

Hi All,
Have a scenario in place where we are collecting multiple flat files on ECC and using append mode on the receiver file adapter to create a single file for final output. We are only interested in submitting the output to it's target after all files sent to PI have been appended.
Does PI 7.0 lock the appended file until all files have been appended so I am sure I end up with a complete single file on output? If not, what are my options to ensure a completely appended file is output? Would it be a viable option to pass the appending file through another sender file adapter using 'msecs to wait before modification check'?
Thanks!
Don
Edited by: donald.meredith on Dec 1, 2011 2:31 PM

How many files are you collecting from ECC and appending at receiver side and how much time it is taking to complete the process?
if its possible to schedule your business to read data from FTP after completing append then no worries, else sometimes it creates trouble.
The option you mentioned is reliable one , but you ended up creating one more interface.

Raj

Regarding file append

Hi Guys,
I have a requirement to append a file from 2 files.
I mean, i have 2 files at my source and i need that 2 files as one file in target.
so iam using 2 sender communication channels to pick 2 files from source and 2 communication channels for target. one receiver channel to create a file and another communication channel to append to the first file.
file A
file B from Source
and File C in the receiver
channel1 to pick file A source file name "A.txt"
channel2 to pick file B source file name "B.txt"
channel3 to create file C target file name "C.txt"
channel4 to append to fileC target file name "C.txt" with append mode.
After all the efforts i found file B is not appending to file C.
Note: all the 3 files have same structure.
I dont want to use BPM
Guys, Please suggest. Productive solution is highly appreciated..
Thanks,
Madhu

Hello Madhu,
What is the criteria (Processing Sequence) to pickup the files from Source Directory? (By Name or Date)
Select accordingly in the sender File CC with wild card entry (*.txt) for File Name convention.
Also In the Sender File CC, use EOIO as QOS which ensures the correct order of execution.
In the receiver CC, use Append as file construction mode.
So one File Sender CC & one File Receiver CC required is enough for your requiremet.
Thanks,
Gujjeit.

Binary file appended instead of created

I have two machines for data acquisition. The first computer (labview 8, 2.8GHz, 1GB ram) contains a pci-6133 and pci 6052e. I am using the 6133 card to acquire 8 analog inputs at 50kHz and the 6052E to generate a trigger pulse. On the second computer (labview 8, 2GHz 512MB ram) I have a pci-6602 that I am using to acquire two channels for buffered event counting. I export the sample clock from the second computer to the first and have them both started on the same trigger. Since I need the files on both computers to be referenced to each other, I generate a timestamp and convert it to a string. Then, using the shared variable engine I share the string between both computers for use in generating filenames. For example, I concatenate "Tracking_","<timestamp>",".dat" on the first computer and "Spectrum_", "<timestamp>", ".dat" on the second computer. Whenever I stop and start the data acqusition I want a new file created on each computer with the correct filename.
I set the open/create/replace vi to "create only" on both computers. When both computers are running, computer two successfully creates a new file with the correct filename and saves the data until the acquisition is stopped. However, with both computers running, computer one only creates a file once after I initially start the vi. When I stop the data acquisition and restart it (without stopping the vi), computer one appends the new data to the previous file and no more new files are created.
When only computer one is running (and I generate the sample clock from a spare counter) , the code works correctly. A new file is created when the data acquisition is stopped and started.
From the symptoms, it would seem to be a problem with the use of the shared variable engine but I am not sure how. Any help on this problem would be appreciated.

Without a look at your code, I am correct in understanding that the filestamp from the shared variable will 'name' the file?
In that case make sure you get a 'new' timestamp.
