Concept of Global Container or Global Variable

Hi friends,
My Scenario is from JMS to SOAP.
I need to store some data when it comes to XI from JMS.
When the response comes back from SOAP I need to add these fields and send back to JMS.
Can I do this Scenario without using BPM ?
Is there any concept like Global Container which I can use it in different Message mappings?
Thanks and regards,
Jose

Hi,
This object enables you to cache the values that you want to read again when you next call any user-defined function in the same message mapping. Note that the sequence in which user-defined functions are called is predefined. It depends on the position of the target fields that the function was assigned to
On details of global container refer these.

  • OSB - global variable substitute?

    I have a simple-looking requirement - I need to keep a single String value between OSB service calls. The value is retrieved from a message and is inserted into each upcoming message of the service, acting much like a simple cache. My question is, OSB lacking global variables, what are the options for keeping this String value in?
    (cluster-wide deployment is no concern here, we can think of it as a single-node problem)

    Re: Are there global variables in OSB??
    Re: OSB: What is best practice for reading configuration information
    OSB is lacking concept of global variable. But the use case can be accomplished with little or no effort using OSB constructs (Java callout, implementing this logic in separate service etc )

  • Making dll from VI containing labview global variable ?

    I've made dll from VI containing labview global variable.
    But, when I write a c program calling a function from the dll, it returns just error.
    The goal is to read a labview global variables from c program. What can i do for it ?

    Hi
    If you don't use the dll in your LV app, it will be difficult, because it will be in the adress-range of you c app. So any writing of values to the global variable in LV, won't affect the variable in the dll.
    What you can do is some kind of client-server architecture. You need a third app, which just does the data exchange - so you should be able to write a value from LV and read it from c.
    There already have been discussions about similar topics - just search the forum.

    Thanks Saish,
    Your response is really appreciated. Sorry about that
    as i didnt know there is 'code' formatting button,
    and I will look into the Singleton pattern.
    As I'm still in the learning stage. Therefore, i
    still have a lot of thing do not understand.
    ... use it in a method signature ...What is "a method signature" ?
    A method signature is basically the method's parameters, return value, name and any access or other modifiers. The following is a method signature:
    static final public void main(final String[] args)Between the braces of the method body is the implementation (or as I already alluded to, the method body).
    Consider using an already-developed connection poolimplementation, such as Jakarta Commons DBCP ...
    I'm trying to implement the Jakarta DBCP. Did I go
    into the wrong way?
    Sorry, did not read the imports. Yes, you are. However, I am confused about what you are trying to implement. You have a static method getDataSource(). You also have a static variable 'ds'. Use one or the other. I would be that there are seemingly random errors cropping up based on whether you remember to call getDataSource() or not.
    You do not, generally, want the data source to be static. Multiple threads might use the class. And if there is only a static data source, you will either need to synchronize the methods that use the data source (resulting in a scaling bottleneck) or not synchronize them (which will totally destroy any concept of a logical unit of work or database transaction).
    .. A static datasource, as in your class, can onlysafely be used by one thread at a time, potentially
    introducing scaling bottlenecks (or race conditions)
    in your system ...
    So, you mean there is no need for the DataSource to
    be static ?
    No, in fact, IMO, it should not be. That is why you are pooling. Use instances. The pool will manage the connections and their availabilty for you.
    Why are you throwing GeneralException everywhere?Here's a question: can someone using your class (a
    caller) realistically be expected to handle a
    database exception?
    When there is a database error, I just want to stop
    the process and redirect the user to an error page. I
    will look into the unchecked exceptions. Thanks.
    Unchecked exceptions do not need to be declared in a method signature or caught within the method body. Checked exceptions do. As such, an added benefit is that unchecked exceptions de-clutter your code.
    In your initResources() method, what happens if theclose() on ResultSet throws an exception
    Oh, yes. I'm so stupid.
    Now I only have ...
         private static DataSource ds;     // set this to
    be static so all threads share the same obj in JVM
         private Connection conn;
         private CallableStatement cs;
    private void initResource() throws GeneralException
    n {
         try {
              if(cs != null) {
                   cs.close();
    logger.info("CallableStatement has been
    as been free");
         } catch(Exception exception) {
         logger.error(exception.toString());
    throw new
    throw new GeneralException(exception.toString());
    You still have issues.
    public void initResources() {
       if (rs != null) {
         try { rs.close(); } catch (SQLException ignore) { ignore.printStackTrace(); }
       if (stmt != null) {
         try { stmt.close(); } catch (SQLException ignore) { ignore.printStackTrace(); }
    }Normally, this type of method would not be called initResources() but rather closeResources() or freeResources(). It would be called from within the 'finally' block of another method using the CallableStatement or ResultSet.
    This is really is problem, would you mind to tell me
    how to handle this(close the connection) if the
    close() on either CallableStatement or Resultset
    throws an exception ?
    See above. Simply log the exception (there is usually nothing meaningful you can do if a close() fails, and it is up to you as a developer if this is an error or just a warning). Another option is to 'chain' exceptions. In your own exception, add a method 'addException(Throwable)'. This would add another exception to a List of exceptions. When you print the stack trace, iterate through the chained exceptions to print them all out. One place where I find this useful is rollback() code. If the original SQL statement fails AND the rollback fails, I definitely want to see that rollback() exception as well in my logs.
    The DB thing makes me headache. What I actually
    wanted is a solution for:
    Let say I have a class "HelloAction.class" contains
    the code:
    public ActionForward XXX() {
         DbManager DB = new DBManager();
         ... do some DB thing here...
         SecondClass SC = new SecondClass();
         SC.doSomeOtherDbThing();
         ... do something else...
         ThirdClass TC = new ThirdClass();
         SC.doMoreOtherDbThing();
    }There are some functions in SecondClass.class and
    ThirdClass.class that will need database connection.
    I consider 'global variable' is because I want these
    two classes are able to use the same
    connection(DbManager) from the function -
    ActionForward XXX().
    What is the best way to implement the above situation
    (sharing the same connection in different classes &
    sub-classes?
    I also just realize that the problem of multi-threads
    with these two class variables..
         private Connection conn;
         private CallableStatement cs;Really headache. I really appreciate any comments.
    Thanks.
    - myyPass the Connection or DataSource to each method or constructor. Call commit() or rollback() from the method that created the transaction.

  • Control global variable used in sub vi

    Hi,
    I've created a vi to read an instrument and to initiate its calibration with labview. This VI stores data in a global variable containing measurments and status of the instrument.
    Now what I'm trying to do is create a sub vi with this to read&write 2 exactly identical instruments so I can finally create a VI that read all 3 instruments simultaneously.
    How could I create a control on the global variable used by the sub VIs since it is the only thing that will change along with its COM port ?
    I included a screetshot of the current VI.
    Thanks,
    Attachments:
    Read_Calibrate.PNG ‏61 KB

    I would make an array of values and then you just pass in which value to update.  I would actually take it a step further and make an Action Engine that can update the data and return the data.

  • How to Use Transient View Objects to Store Session-level Global Variables

    hi
    Please consider section "40.8.5 How to Use Transient View Objects to Store Session-level Global Variables"
    at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcstatemgmt.htm#ADFFD19610
    Based on this documentation I created the example application
    at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.01.zip
    It behaves as show in the screencast at http://screencast.com/t/qDvSQCgpvYdd
    Its Application Module has a Transient View Object instance "MyEmployeesContextVOVI", as master for the child View Object instance "EmpInCtxJobVI".
    On rollback the Transient View Object instance keeps its row and attribute values.
    Also when passivation and activation is forced (using jbo.ampool.doampooling=false ) the Transient View Object instance seems to keep its row and attribute values.
    questions:
    - (q1) Why does the expression #{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty} evaluate as true when a Transient View Object instance attribute value is changed (as shown in screencast at http://screencast.com/t/qDvSQCgpvYdd )?
    - (q2) What would be a robust approach to make a Transient View Object instance more self-contained, and manage itself to have only one single row (per instance) at all times (and as such removing the dependency on the Application Module prepareSession() as documented in "5. Create an empty row in the view object when a new user begins using the application module.")?
    many thanks
    Jan Vervecken

    Thanks for your reply Frank.
    q1) Does sample 90 help ? http://blogs.oracle.com/smuenchadf/examples/
    Yes, the sample from Steve Muench does help, "90. Avoiding Dirtying the ADF Model Transaction When Transient Attributes are Set [10.1.3] "
    at http://blogs.oracle.com/smuenchadf/examples/#90
    It does point out a difference in marking transactions dirty by different layers of the framework, "... When any attribute's value is changed through an ADFM binding, the ADFM-layer transaction is marked as dirty. ...".
    This can be illustrate with a small change in the example application
    at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.02.zip
    It now shows the result of both these expressions on the page ...
    #{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty}
    #{bindings.MyEmployeesContextVOVIIterator.dataControl.dataProvider.transaction.dirty}... where one can be true and the other false respectively.
    See also the screencast at http://screencast.com/t/k8vgNqdKgD
    Similar to the sample from Steve Muench, another modification to the example application introduces MyCustomADFBCDataControl
    at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.03.zip
    public class MyCustomADFBCDataControl
      extends JUApplication
      @Override
      public void setTransactionModified()
        ApplicationModule vApplicationModule = (ApplicationModule)getDataProvider();
        Transaction vTransaction = vApplicationModule.getTransaction();
        if (vTransaction.isDirty())
          super.setTransactionModified();
    }Resulting in what seems to be more consistent/expected transaction (dirty) information,
    see also the screencast at http://screencast.com/t/756yCs1L1
    Any feedback on why the ADF Model layer is so eager to mark a transaction dirty is always welcome.
    Currently, question (q2) remains.
    regards
    Jan

  • Function module Global variables not cleared from memory?

    Hi,
    This is may be simple & stupid question ( after posting  4242 posts ):)
    " Declaration in TOP
    data : begin of i_y1yatt occurs 0.
            include structure y1yatt.
    data : end of i_y1yatt.
    types: begin of t_yatt71.

    data : i_yatt71 type standard table of t_yatt71

    This is code in the function module.
      loop at i_y1yatt.
        move-corresponding o_y1yatt to i_yatt71.
        if i_y1yatt-werks eq 'N501'.
           move space to i_yatt71-werks.
        endif.
        append i_yatt71. 
        " Here this internal contains the previous entry
        clear i_yatt71.
      endloop.
    This function module is called 25 times in a minute.
    My problem is this
    For example : 1st tranmission is called this fm with 50 records,
    and 2nd tranmission is called fm with 10 records.
    My results are showing
    last record in the 1st transmission is still on the memory while calling 2nd transmission.  ( Here in int table I_YATT71 still contains the 1st transmission's last records during the 2nd tranmission call)
    As per my knowledge if each time calls comes in to fm all gloabl variables get cleared. but some how this not happening.
    Anybody come across this scenario.
    PS. I know i need to use clear statement within the loop as first statement.
    a®

    You must understand that when calling a FM, you load the entire function group into memory. IF there are global variables, then they are "alive" for the entire duration of the program execution. Meaning if you call the function numerious times, or even if you call another function within the same function group, the functions still have access to that same global variable space, so it must always be cleared manually by the developer at the required points.  You can not rely on the runtime to clear the global variables at the end of the function call.  So you should clear all you globals as the first operation in your function module call, if that is what is required.
    Is this clear?

    Rich Heilman

  • Can I use the timestamp of a Network published global variable to reduce network traffic?

    I would like to use a couple of network-published global variables that will contain large clusters of data.  I want to host them on one device but read them from several - consider a distributed control system.  The data will update very infrequently, but, when it does, I want all my HMIs to know quickly.  I can have all the HMIs just read the data 4x/second (that would be fast enough) but I was wondering if there is a more elegant solution (still using global variables).  If I read only the timestamp 4x/second from each of the HMIs, compare it to the last read, and then poll the whole variable only if the timestamps are different, will that require less resources than just grabbing the whole variable every time?  In other words, does reading the timestamp use the same amount of resources as reading the whole variable?
    With really simple code, assuming the "Setup Data" cluster is quite large, does....
    ...get me any advantage over...

  • Dynamic call of a vi with a reference stored in a global variable

    Hello,
    I am trying to program a VI which calls DAQmx functions in some cases, in other cases DAQmx may not even be installed. To prevent a broken arrow on machines where DAQmx is not installed, I want to use a sub-VI containing the DAQmx function calls which is called dynamically by a main VI. For speed I want to prevent continuous opening and closing the VI reference, so I want to store the reference to the sub VI in a global variable. In this variable I also want to store the Analog Input Task. I want to use an initialization VI to write the VI reference of the sub VI and to configure and start the Analog Input Task and write the Task ID to that Global, too. In that way I was hoping to be able to improve the performance of the dynamic calls and the Task calls. BUT - when I write the refererence and task to the Global and read it out from another VI, the reference is not valid anymore and the Analog Input task is also not valid, even if both the initialization VI and the Global are still open (but not running). Does somebody have an idea how to solve that? It is a bit difficult to describe, so here is what I want to do in a shorter description :
    - run a initialization VI which
      defines a reference to a sub VI which will be called dynamically later on
      and a AI task ID definining a DAQmx physical channel configuration to use for subsequent read cycles
      and writes both (VI reference and AI task) to a global variable
    - run another VI which
      reads the VI reference of the VI to call dynamically from that global
      runs the corresponding VI dynamically
      the dynamically called VI performs an AI task corresponding to the DAQmx task ID read from that global (it reads an analog value for instance from the  
      physical channel configured by that AI task) 
    Why all that? To prevent creating and destroying the VI reference for each call of the sub VI for speed. And to use the configured DAQmx channel for subsequent read tasks only if the subVI is called dynamically - if it is not, then the application will not see the DAQmx calls and therefore no broken arrow will occur if no DAQmx is installed on the machine.
    Can somebody help me with this? Why can't I store and read out the reference to the sub VI to/from a global, and why is the AI task not valid when read out from the dynamically called sub VI? I am somewhat lost with all that...
    Thanks in advance,
    Gabs

    Uh - I am almost getting crazy with that
    Kevin, that solution is the right one for programming an application. In that case everything will work fine. But during testing, it is more convenient to call all VIs from their front panels one after another. That's how I'm doing it for everything that needs to be exchanged between such VIs: store them either in a global or in a functional global variable. In that way the user can "play around" with the VIs without wiring them together in a main VI. Therefore, after some thinking I liked Davids idea with that daemon VI (I solved that by adding a boolean in the initialization VI to choose if that daemon is necessary - during testing phase - or not - when using the VIs in a main application). BUT:
    David: It does not work!!! I have exactly done what you proposed and this daemon VI is really running, having a True/False frame with a constant of False wired to the selector and holding both the functional global and the dynamically to call VI in the True frame. In that way, after initialization is finished, both VIs are still running but idle. Anyway, when I read back the value of the reference or the DAQmx task, it is invalid again!
    That really costs just too much time. Does anybody have any idea what to do now? David, I was hoping that your suggestion would solve the problem, because it would be logical that it would - why then is LabVIEW destroying the reference and task anyway even if that daemon VI containing the functional global is still running???

    Gabs

  • Call function in LabView from a DLL, then access global variable from DLL

    I have created a DLL in LabWindows with a function and a structure.  I want to call the function from within LabView and then access the global structure.  I am able to call the function from the DLL with a "Call Library Function Node" and can access the return value, but I cannot figure out how to access the global structure.  The structure is declared in the DLL header file with __declspec(dllimport) struct parameters.
    Is there any way of accessing this structure without using the Network Variable Library?
    Solved!

    dblok wrote:
    When you say "access to" or "the address of" the global variable, do you mean to pass the variable as an argument to the function call in the DLL?  If so, then I was not really sure how to pass a cluster from LabView by using the "Call Library Function Node".
    Yes, that's exactly right.  I would include a pair of helper functions in the DLL to read and write the global variable.  Alternatively you might write separate helper functions for each field inside the global structure, depending on the number of fields and whether you want to do any validation on the values.
    You can pass a cluster by reference to a function that expects a struct by setting the parameter to Adapt to Type, so long as the cluster does not contain any variable-length elements (strings or arrays).  The cluster needs to match the struct exactly, and sometimes that involves adding extra padding bytes to make the alignment work.  Variable-length elements in LabVIEW need to be converted to clusters containing the same number of elements as the struct definition (for example, if your struct contains char name[12], you would create a cluster of 8 U8 values, and you could use String to Array of Bytes followed by Array to Cluster to convert a LabVIEW string into that format).  If the struct contains pointers it gets more complicated, and it may be easier to write functions in the DLL to access those specific elements individually.
    If you can't get this working or need help, post your code and an explanation of the error or problem you're seeing.
    EDIT: it is also possible to include a single function in the DLL that returns the address of the global variable, which LabVIEW can then use to access and modify the data, but that's more complicated and likely to lead to crashes if you don't get the memory addressing exactly right.

  • Global Variable in entity beans

    Dear Friends,
    For example let us think that we have an entity bean for Customer.
    and we created an instance of that bean for customer A and then for customer B.
    So will the global variables in Customer bean be shared across Customer A and Customer B or will there be seperate instances for both Customers.
    Thanking You,
    Chamal.

    Your concepts seem to be a little messed up.
    For entity bean, remember the following:
    1. each object/instance of entity bean represents a record in a database
    2. when a client looks up an entity bean (typcially by using findByPrimaryKey method on home object), the record from database is searched and its values are stored in Entity Beans variables (this is probably what you mean by Global Variable. But thats an incorrect terminology in Java/J2EE. Class attribute is the correct word)
    3. In step 2, you fetched a record and that record is represented by a java object, which is nothing but entity bean.
    4. Now if you make changes to this java object, these changes will persist in the database. That is the essence of entity bean.
    5. If you use the home object's findByPrimaryKey method and look for the same record, no new object will be created. The 2 remote objects will point to the same entity bean on the server.
    6. If yo use the home object's findByPrimaryKey method and look for another record/customer, a new object will be created on the server. This new entity bean will map to the new record.
    Note taht the attribtues of CustomerA and customerB will never be shared.
    hope that helps

  • How to pass the global variable in enter_query mode

    Dear Friends
    I am calling the form and in enter_query mode ,but my global variable is not pass to the form when it is in enter_query mode , me be the field is clear after the enter_query is called ,in which triger do I have to keep my variable
    :H_DOC_CODE := :global.offer_no ; so that it will be assign to the field
    :H_DOC_CODE this my script is keept in
    WHEN-NEW-FORM-INSTANCE.
    waiting for your valuable answer.
    best regards
    Jamil Alshaibani
    -- this my script
    DECLARE
         V_STATUS NUMBER;
    BEGIN
         :system.MEssage_level := 25;
         :GLOBAL.V_STATUS := 0;
         CLEAR_FORM(NO_VALIDATE);
         enter_query ;
    :H_DOC_CODE := :global.offer_no ;     
    END;

    I'm not quite sure what you mean with
    But the document number is not pass to the called form field and : H_DOC_CODE is a field in the called form.Do you want that the form is in ENTER-QUERY-mode and the field H_DOC_CODE contains the field of the GLOBAL?
    Or do you want to automatically execute a query with that H_DOC_CODE.
    For the first, you have to assign the global in the WHEN-NEW-RECORD-INSTANCE-trigger instead of the PRE-QUERY:
    IF :SYSTEM.MODE='ENTER-QUERY' THEN
      :H_DOC_CODE :=:global.offer_no ;
    END IF;For doing an automatic query the suggested solution with the PRE-QUERY-trigger is right, but you would have to issue an EXECUTE_QUERY in the WHEN-NEW-FORM-INSTANCE instead of an ENTER-QUERY.

  • Need features of global variables but want to avoid re-writing to memory

    I am making a program with a number of simultaneous loops that will be sharing several variables. Most of the variables are of size 1 or small arrays, so I am not too concerned about the constant re-writings involved. However, I have one rather large data buffer (3D array containing 200Kb+ of data). The buffer will be of a set size. In the various loops, the buffer will be accessed for updates (generally with Replace Array subset), and read from to get average values and such. I'm using semaphores so that none of the loops interact negatively and lose data. In other programs I'd set this up with a shift register in the loop, but since the data is being used in separate simultaneous loops, it's no
    t really possible to wire it up that way. I need some sort of memory-space that can be accessed from the various loops.
    I guess in sorts, I need to be able to have global variable 'pointers', but of course I was told a couple of years ago at a LabView seminar that pointers was a bad word.

    I have one correction to make. The value of an unitialized shift
    register on first load is not undefined but rather contains the
    datatype's default default value. This would be False for booleans, 0
    for numerics and empty arrays or strings.

  • Reading a global variable from tomcat with JNDI. Example not working

    Hi you can help me to make this example work?
    Context initCtx = new InitialContext();
    Context envCtx = (Context)initCtx.lookup("java:comp/env");
    Object o = envCtx.lookup("testvariable");
    <GlobalNamingResources>
    <Environment name="testvariable" type="java.lang.Boolean" value="false"/>
    Nice greetings Christian

    I found out that in addition to having the JNDI lookup code, you have to
    - have the environment variable declared in the app server configuration
    - have a resource-env-ref entry in your webapp module
    - have the application container bind your named variable with the global variable
    I am using tomcat 5.5, and have done the following. with success.
    the following example uses the default sample environment variable in the tomcat server.xml
    in tomcat server.xml:
    <GlobalNamingResources>
    <Environment
    name="simpleValue"
    type="java.lang.Integer"
    value="30"/>
    </GlobalNamingResources>
    in my application's web.xml:
    <resource-env-ref>
    <description>Test read resource environment variable</description>
    <resource-env-ref-name>simpleValue</resource-env-ref-name>
    <resource-env-ref-type>java.lang.Integer</resource-env-ref-type>
    </resource-env-ref>
    in my META-INF/context.xml (or otherwise, in tomcat's context deployment configuration)
    <ResourceLink name="simpleValue" global="simpleValue"
    type="java.lang.Integer"/>
    Note: in theory, the named resource by your web app could be different from the global environment variable, but here they are the same 'simpleValue'
    This is the really important step, that with out it, nothing works.,
    the context.xml is known to work with tomcat when it exists in META-INF/context.xml inside the .war file (i use war files to deploy, but you should be able to create META-INF/context in an unpacked webapp directory too, and tomcat will find it.,
    I can not say what it is like for other app servers, but this mapping step is the critical point that i discovered after A LOT of hair pulling.
    then, make use of it, i created a jndiTest.jsp:
    <%@ page import="javax.naming.Context" %>
    <%@ page import="javax.naming.InitialContext" %>
    <%@ page import="javax.naming.NamingException" %>
    <%
    try {
    Context initCtx = new InitialContext();
    Context ctx = (Context) initCtx.lookup("java:/comp/env");
    Object o = ctx.lookup("simpleValue");
    %>
    <%=o%><br>
    <%
    catch (NamingException ex) {
    System.err.println(ex);
    %>
    since my server.xml defines the value for 'simpleValue' to be 30, this page displays 30

    Yes, that is a better way to say it.
    If so, how 'bout putting them in a user-visible service object?
    Remember, "user-visible" is Forte's mis-terminology for
    "partition-visible." No law that I'm aware of says you can't put
    a user-visible service object in a server partition.
    Unfortunately all Forte Service Objects share a single name space. I
    thought from the documentation that User Visible Service Objects would work
    for me. However, when I tried User Visible Service Objects, they didn't
    quite do the trick because what I wanted was identically named service
    objects that resolve to a different local instance for each partition. So
    no matter where my code was running, it could call ProcessLocalStore.Foo()
    and it would get the ProcessLocalStore for that partition. Note that I am
    not talking about replicated partitions. Even though they are called
    "user-visible service objects, there can only be one instance of the named
    service object in any given Forte environment.
