How synchronous read operation is outbound operation?

Hello,
1. what is the difference between read and synchronous read in file adapter?
2. how synchronous read operation is outbound operation? Read must be an Inbound operation.
Please clarify.
Thanks in adv,

1. what is the difference between read and synchronous read in file adapter? Read is use for polling. Read option will initiate a new instance(and you will use a receive activity - inbound).
2. how synchronous read operation is outbound operation? Read must be an Inbound operation. Synchronous read is being used from an existing instance (process). You will use an invoke activity for that - you are sending a request to read a file (file/directory name etc..). You are then getting back the result (file content etc....).
Hope that answered your question.

  • Passing file name dynamically in Synchronous read operation of FTP adapter in OSB

    Hi,
    We are implementing the integration in OSB 11g and using FTP JCA adapters to check if the file exists in the FTP location or not. We are using Synchronous read operation of FTP adapters. We need to pass the file name dynamically at run time. In the JCA file we can hard code the file name. How that file name can be taken dynamically using OSB.
    Regards,
    Sharmistha

    Hi Sandeep,
    This is possible.
    For creating filenames dynamically for your sender, you will have to crate a variable name ( eg: %VAR%) as you file name and then you will have to give the name of your file under variable substitution. Just check this link for more info,
    http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm
    In the case of receiver file adapaters, you have 5 options for file creation like,
    1.Create
    2.Append
    3. Add time stamp
    4.Add Counter
    5. Add Message ID
    You can choose any of these options or you can do it dynamically from you payload. Just check out this help link for more info,

  • Synchronous Read operation in File Adapter

    Hi All,
    Can anyone explain me on 'Synchronous Read' operation in File Adapter.
    Thanks,
    Rakes

    There are 3 options for the file adapter.
    - Read used for polling files to invoke a BPEL process
    - Write used writing out a file, generaly used to finish a process
    - Sync Read is used to read a file in the middle of a BPEL process.
    What I mean by middle of a process is, a BPEL process can be invoked using a WSDL. The BPEL process can perform some operations and may need to read a file as part of that process as a file provides some information important to the process.
    A real life example would be having a java progaram that invokes a BPEL process via a WSDL. This application asks to process a file xyz in directory abc. You would get this variables from WSDL and read the file approprately.
    This is also an example of processing a file based on business rules in your BPEL process.

  • How to read image file in bpel..

    i want to pick up image files of format .jpg & .png in bpel..
    Thanks...

    Hi,
    Ok, got your flow. I'd recommend start small and simple.
    Receive
    Assign
    Invoke - Invoke File adapter using Synchronous Read Operation (Normal Read operation will not work in the middle of process) with Opaque schema and by specifying the exact file name.
    I think you can't specify the file name as regular expression in Sync Read operation.
    Also follow the below link for more details on how to achieve your requirement.

  • How can I configure ReFS to NOT fail read operations when a checksum error is detected (on non-Storage-Spaces volumes where data integrity streams are enabled)?

    According to William Stanek, in his Windows Server 2012 R2 Inside Out: Configuration, Storage & Essentials book, this is apparently possible: (pg. 615 - here it is on Google Books: https://books.google.ca/books?id=0IyfBAAAQBAJ&pg=PT819&lpg=PT819&dq=read+operation )
        Integrity can be enabled when the system is not running on Storage Spaces. When
        integrity is enabled and ReFS detects a checksum mismatch, ReFS logs an event and
        fails the read operation by default. If you don’t want the read operation to fail, you
        can configure ReFS to continue with the read operation. A related event will be logged
        regardless.
    So then how do I configure it to do that???
    (And just to make it super-clear, I'm NOT using Storage Spaces, so there is no redundancy via mirroring/parity, and I'm not expecting any file repair - just detection of corruption. It's just a basic volume formatted with ReFS and
    with integrity streams enabled, via format E: /fs:ReFS /i:enabled
    For those who want more details, here's the situation: 
    I try to perform a read operation on a file with corrupted data (purposely done for testing using a low-level disk editor), I get a the following error message:
    And an event ID 133 from ReFSv1 gets logged in the System log:
    Clicking "Try Again" just brings up the same message, and clicking "Skip" skips the operation entirely.
    This is indeed the correct default behaviour.
    What I want instead is for the read operation to be allowed to complete, with corrupt data and all, and ONLY for the event to be logged. And according to William Stanek, this is supposed to be configurable somewhere - and after hours of searching, I haven't
    been able to find anything.

    Hi Tommy,
    >>How can I configure ReFS to NOT fail read operations when a checksum error is detected
    We can use PowerShell command Set-FileIntegrity to configure this. The specific parameter for controlling this behavior is
    -Enforce <Boolean>which indicates whether to enable blocking access to a file if integrity streams do not match the data.  
    Regarding this point, the following article can be referred to as reference.
    Set-FileIntegrity

  • Need  file adapter polling with read operation to be triggered by a BPEL without using synchronous read

    The scenario is:-
    Web Service Client -->input-->BPEL-->if input valid-->trigger file adapter with read operation--> receive file
    i am not able to stop the polling until it is required to trigger the polling.
    As soon as i deploy the composite the file adapter starts polling without waiting for input.
    Since i am using two receive activities, the second one which is suppose to receive file from file adapter is always showing pending state. (asynchronous callback)

    Hi there,
    IMHO the traditional read is used only as inbound operation, that means
    that it starts polling the input folder as soon as the composite gets
    deployed - which is the same you are experiencing.
    In your case you need an outbound operation that needs to be invoked at
    a certain moment. I don't know what are the reasons not to use sync
    read, but this is the only outbound read operation supported by the
    adapter. If you can not use the sync read, then you would have to design
    some custom solution where you call a web service or EJB for instance
    that reads the desired files.
    Another option I can think of, though have not use personally is using
    the adapters programatically in Java - take a look at this blog post as
    it seems related to this topic -
    https://technology.amis.nl/2012/01/22/using-the-oracle-weblogic-technology-adapters-with-custom-java-message-driven-bean-mdb-triggered-by-file-adapter-part-of-the-story/.

  • PCI-6254 DIO Read - Need to know how to trigger the Read operation??

    Hi,
    Can anyone help me with DIO Read operation using PCI-6254 (DAQmx)??
    here'e the breakdown of the issue i'm having:
    i'm doing a DIO Read using DAQmx drivers, and am using "one channel for each line" on the Port 0.
    i'm using another line for DIO Write at the same time...infact the DIO write sends the bit pattern
    and inturn triggers an external device, and am trying to capture the response of ext. device on
    other line thro' DIO READ...
    now, i do see the bit pattern on the Oscope, but am not reading the bit pattern using DAQmx Read?
    (i'm reading all ZEROS)
    Currently, i'm not using DAQmx Trigger? i tried using it, but was getting an error...
    i guess i need to trigger the read when the line goes high/low (for ex)
    can anyone help me with this?
    Regards,
    rkpat

    Hi rkphat,
    DIO operations on an M Series device cannot be configured for triggers. The source of the DIO sample clock must be set up for the trigger and the DIO operation should just be configured to receive that clock. You must provide an external clock or a clock generated by another subsystem, such as an analog input sample clock or a counter pulse train output, to clock digital operations. For example, if you were going to use the analog input sample clock to clock your digital measurements, you would configure your AI subsystem to receive a start trigger and to use an internal clock. Once the trigger arrives, the AI Sample clock is generated and passed to the DIO subsystem. Or if you wanted to use a counter to generate the clock, you would set the counter up for pulse train generation with a digital start trigger.
    If you post your code we can find out why the Digital Read is not returning the correct data.

  • Error "logical end of file reached during read operation"

    I am trying to burn a dvd of a wedding I did, and this is the error I am getting. After 5 hours of it trying to burn when I click cancel this it says " logical end of file reached during read operation". Does anyone know what this means, and how I can fix it? I am anxious to get this wedding finished and out to the customer. Any help would be greatly appreciated.

    How long is the wedding video?
    My standard list of things to do first...
    Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
    Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system.
    Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
    Run Cache Out X (free download) to clear all system and application caches.
    Reboot your Mac.
    If you still can not get it to run correctly, next thing to try is to throw out the iDVD preference file (don't forget to change back those preferences you want different from the defaults next time you run it). If it still doesn't work, then I would suggest you reinstall iDVD.

  • JZ0T3: Read operation timed out

    Hi! I'm trying to solve this problem for a while and actually I couldnt find the cause of the problem.
    For some reason, deep inside the code of my application that error happends when I execute some inserts on the same Sybase table (they could be performed concurrently). I said "deep inside the code" since if I test a similar code, but outside the application (that is, just executing the inserts in a stand alone java main) the problem can't be reproduced.
    The connection is obtained normally as follows:
    try {
    Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
    }catch (ClassNotFoundException e) {
    System.out.println("Oops!");
    Connection conn = DriverManager.getConnection(url,user,psw);
    conn.setAutoCommit(true);
    The driver been used is jconnect 4.5
    Then, several inserts are performed:
    String exampleQuery = "INSERT INTO SampleTable (id) VALUES ("1")\nSELECT @@IDENTITY";
    PreparedStatement stmt = conn.prepareStatement(exampleQuery);
    ResultSet rs = stmt.executeQuery();
    if (rs.next())
    System.out.println(rs.getInt(1));
    Some of the query executions raise the following exception:
    java.sql.SQLException: JZ006: Caught IOException: java.io.IOException: JZ0T3: Read operation timed out.
         at com.sybase.jdbc2.jdbc.ErrorMessage.raiseError(ErrorMessage.java:485)
         at com.sybase.jdbc2.tds.Tds.handleIOE(Tds.java:2961)
         at com.sybase.jdbc2.tds.Tds.nextResult(Tds.java:1796)
         at com.sybase.jdbc2.jdbc.ResultGetter.nextResult(ResultGetter.java:69)

         at com.sybase.jdbc2.jdbc.SybStatement.queryLoop(SybStatement.java:1455)
         at com.sybase.jdbc2.jdbc.SybStatement.executeQuery(SybStatement.java:1440)
         at com.sybase.jdbc2.jdbc.SybPreparedStatement.executeQuery(SybPreparedStatement.java:70)
    I've just found a workarround to solve this problem: synchronizing the execution of the query. That seems to avoid concurrent insertion.
    The funny thing is: when I extract the code from the application and execute it in a stand alone java main, even stressing with multiple threads executing batch inserts in a for clause, the problem NEVER happends.
    Any tip is welcome since I actually don't know what to do. Thanks a lot, I hope anyone replies!!
    Bye!

    Hi Sean,

  • How to call Operating System commands / external programs from within APEX

    Hi,
    Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
    E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
    c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
    Any pointers will be greatly appreciated.
    Thanks & Regards,

    Hi Guys,
    I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
    However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
    sqlplusw.exe user/password@database @script1.sql
    sqlplusw.exe user/password@database @script2.sql
    sqlplusw.exe user/password@database @script3.sql
    sqlplusw.exe user/password@database @script4.sql
    What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
    Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
    Any help will be greatly appreciated.
    Thanks & Regards,

  • How do set operation timeout in tomcat server?

    hi all
    suppose i have one endless loop program(jsp) that program run under tomcat server,
    so it's keep on runing in tomcat server.
    i want, after some time the server send error message like operation timeout.
    how do set operation timeout in tomcat server?
    if anybody know help me.
    my mail id [email protected]

    Well, the server.xml file has connection time outs, but that is for idle time, I think... I'm not sure what would happen in a loop... , especially if you are sending some data back to the client in each iteration. Generally you shouldn't be starting a loop that will really run forever. Maybe have some type of counter to break out if something hasn't occurred within x iterations, or create a separate thread that can sleep for x seconds and set a flag to break the loop after that time.

  • Invoking Composite from BPMN with file read operation

    hello,
    I have a composite which does a simple file read and dumps data to database using mediator.
    right now composite gets kicked off by presence of a file in a directory.
    I would like to invoke this composite from a BPMN process, unfortunately because of nature of file adapter created through composite, jdeveloper doesn't expose the FileAdapter read operation as WSDL so I cannot create a service task out of it.
    How can I invoke composite directly without having to create a file adapter at the BPMN level and take care of transforming the records to DB adapter?
    thanks.

    As you guess, it is stored in the PSD, but only with the Maximise Compatibility switch. Without that switch, a dummy image is stored which has the text "This layered Photoshop file was not saved with a composite image.", in English, German, Japanese and French.
    My program
    psdparse extracts each layer in an 8-bit file as a PNG, and the merged image for both 8- and 16-bit files. That link is to a Subversion repository containing source code.

  • 11g fileadapter - read operation triggered by file

    Hi,
    I have practiced with the new file adapter feature to trigger a read operation by an endfile. The read operation that is triggered by a file is useful in specific scenario's, but I have a question about it.
    There is no correlation between a file and a trigger file. What will happen when multiple files are written at once with multiple corresponding trigger files. How does the engine knows which trigger file belongs to which fle so that the correct completely written file is processed? I do not have a clear answer on this question yet.
    I know that the current 11g tech preview is not complete and some features that are in the preview will not survive in the final release, but I am curious about your thoughts about this issue.
    Regards,
    -Tom

    Hi tom,
    The documentation for triggering mechanism is here: http://otndnld.oracle.co.jp/document/products/as10g/101310/doc_cd/integrate.1013/b28994/adptr_file.htm#CIAJCBGI
    In a nutshell, the trigger file is associated with an endpoint and not with individual files for the endpoint directory. Consider a scenario wherein a third party application writes files in some folder and your BPEL process needs to process all the files when a certain marker file appears somewhere in the file system. In such a case, you will define the wsdl as:
    <jca:operation
    PhysicalDirectory="C:\ORAHOME\integration\jdev\jdev\mywork\triggers_proj\inputDir"
    ActivationSpec="oracle.tip.adapter.file.inbound.FileActivationSpec"
    IncludeFiles="Order.*\.xml"
    PollingFrequency="30"
    TriggerFilePhysicalDirectory="C:\foo"
    TriggerFile="Purchaseorder.trg"
    </jca:operation>
    In this example, adapter will start processing the Order*.xml files only when it finds the marker file "Purchaseorder.trg" in "C:\foo"
    Hope this answers your question.
