Global Variable translated to different characters

We recently upgraded BODS from 4.2 SP1 to 4.2 SP4. Now we are facing issues in those DataFlows where are used Hierarchy Flattering functions, that Global Variables are wrongly translated from text to weird Asian characters. E.g. varchar variable: 'abc' is transformed to '扡c'. As data source/target is used HANA. The issue is caused whenever there is any table from HANA datastore 'directly' connected to HANA (attached picture). When used ODBC connection to HANA than it works fine, but then we are loosing Bulk load options.
Attached ATL (with .txt extenstion) has password: abc
Versions:
DS: 4.2 SP4
HANA: 1.0 SP09
HANA Client ODBC: 1.00.09 (tested also on 1.)

Hi Vanda,
668 is the build number. If you search the SAP Notes/KBAs for 14.2.4.668, you'll find the KBA release notes for that version. 14.2.4.668 corresponds to SP4 (patch 0).

Global variable access behaving differently

Hi There,
I am kind of confused at the way the output of this sql;
select
proc1.get_id(dwg_no, rev_id),
proc1.get_adcn(1) from
table t1,
table2 t2
where
t1.pkey = t2.fkey;
PL/SQL (Proc1)
create package proc1
function get_id(
dwg_no varchar2(10),
rev_id varchar2(4)
function get_adcn(
a number
create package body proc1 ..
--declare/set the global variable
v_adcn_no varchar2(4) := null;
funciton get_id (dwgno, revid) as
v_rev_id varchar2(12) := null;
select 'AB', '55' into v_rev_id, v_adcn_no from dual;
return v_rev_id;
funciton get_adcn (a number) as
return v_adcn_no;
My expectation is th get_id function would be executed and the global variable v_adcn_no would be set to '55' so that this value would be returned when get_adcn fucntion is called.
But it doesn't happen so.(i validated this)
[at times i returns 55, at times it returns null]
Actually i simulated my problem with a simple example.
and I do not want to execute the same sql again when get_adcn function is called.
Any help is highly appreciated.
Regards,
Srini

Thx for your reply,
that does not meet my requirement, bcos there is no guarantee that get_rev_id function would be called first before get_adcn.
But my requirement is i want the rev_id function to be executed first, how would i ensure that.

Srini

How can I pass a value field to a global variable?

I have a doubt,
I wnat to know if is possible to pass a value field to a global variable inside of DataFlow?
That a try to do is at the time to execute a JOB on line (real time), depending of the value field that i receive, only certain DATAFLOWS will be executed depending of the value field.
I hope you can help me.
Kind regards!!!

It can be done via various ways, your approach is kind of odd, though.
You are saying you have one kind if Input message, depending on the flag you want to do different transformations. The way you envision that is by loading that flag into a global variable and use different dataflows then.
Can you use different dataflows within one Realtime Job? Yes, usually the first loads an in-memory datastore.
Can you write into a global variable? Yes and No. Not directly, but you can write the value into e.g. a database and using the sql() function read it from there. But why would you. You could write it into the in-memory datastore. And then you run your n dataflows, each has a filter. So only one of these dataflows will actually process the data.
Are there other approaches? I would have a Case transform at the beginning and route the data into different queries depending on the data. So all in one dataflow. Your approach is fine for a batch dataflow where a dataflow is started, does something and then ends. But that's not how it works in Realtime!

There is no "Get Voc/Isc" or "GO" button anywhere on the front panel, and I have no idea what you mean by "Setup Linear Stair Sweep" and "start sweep". Are you sure you uploaded the correct code?
Other VI comments:
You are abusing/misusing global variables.
You already have a state machine, so you can actually code this using just the state machine without actually needing the separate event structure loop. Even if you do keep it, that still does not require you to use global variables.
Why do you have a loop around the Write to Spreadsheet File? This serves no purpose and actually stops your code in that loop until the Stop global is set. This doesn't make much sense.
Since you do not have a path wired to the Write to Spreadheet File VI, you will be asked for a path each time the loop iterates. Use a shift register to hold the value of the path from iteration to iteration.
Get rid of the Build XY Graph Express VI and those Convert to Dynamic Data functions. Replace with a single Bundle function.

How can I handle global variables from different DLLs created based on VIs that access those variables

My goal is to break apart an entirely LabView created application so I can still use parts of it (builded as Shared DLLs upon on some VIs) in my new .Net application. My problem is that some others VIs (that I am not intending using) are changing those global variables (in the natural data flow of the application). I could , of course, send the values of those global variables as parameters, but I don't know how should I pass those data types (and their size)... There are some clusters there...
Any help is well appreciated

Your
problem is of course the use of globals. That is almost always a bad
idea and asking for troubles once your application gets bigger.
Avoiding race conditions and undesired influences between different
parts of your application will take up more and more of your
development time as your project grows.
You should look into Functional Globals (LV2 style globals) and shift
registers for data storage and queues for passing information between
different parts of your applciation. Using these techniques
consequently, will require you to spend some more time initially but
will allow you to grow your application without increasing the
complexity of managing such things exponentially.

How can I run two different vi's in same project which are accessing same global variable with out effecting the speed of the execution of both the vi's

Hi
I have build an Labview project with FPGA target . I have configured an FPGA VI and an host Vi to acquire data and logged the data to a file and stored the latest data in a global variable simultanously. I have configured one more VI in the same project to access the global variable. I have build a dll to access both the VI as functions in LabWindows/CVI code. My task in CVI is to update configured GUI with latest data periodically and run the host VI continously for a long time and log the data to a file. GUI should update for every one second with latest data for this I am using the second VI in which I am accessing the global varibale in which the latest data has been stored in host VI.

How a statics variable different from global variable...

explain the span of these two kind of varaiables in subroutines..with a simple example
Thanks guyz

Check the following syntaxes to declare a static variable.
1. STATICS f.
2. STATICS f(len).
3. STATICS: BEGIN OF rec,
END OF rec.
4. STATICS: BEGIN OF itab OCCURS n,
END OF itab.
Static validity means that, unlike normal local variables, the life of static variables does not depend on the defining procedure, but on the program at runtime. Static variables are thus not redefined on the stack each time the defining procedure is called, but exist independently of this in the program and keep their value, regardless of calls to the defining procedure.
Global Variable:
global variable is a variable that is accessible in every scope.

Use two indicators for the same variable in two different VIs

hello, I want to use two indicators for the same variable in two different VIs running at the same time
should I use global variables?? I want to avoid because I have lot of variables and it would takes too much memory,I tried with this code but the value of the second indicator is not updated
I tried to use the queue and it works but the problem is as i said previously that i have many variables shoud I use a queue for each one??
what should I do?
thank you in advance

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

How do I add a global variable to my app?

Hi all,
I am building a flex app which displays data in different tabs from a mysql database and I wan't to add a sign in process to make sure only registered users of the mysql db can see the data.
To achieve this I built a sign in component which accepts a username, password and the name of the database to connect to. My flex app then uses a php script to verify that the user can connect to the database using the details entered. If not, the sign in component displays an error message, but if sign in details are verified then the user can see the data from the database.
How can I store the details in the flex app for that users session so that when the user queries the db for data, flex uses the details entered during the sign in process to connect to the mysql db and submit the query?
I thought about storing the details as an array in a global variable and then accessing that global variable from anywhere in my app but I don't know if that is the correct/secure way to do what I want, nor do I know how to do it. Any help would be much appreciated.
Thanks in advance,
xander

quick, dirty example, could be improved on but it'll get you rolling;
After user login has succeeded, send off another HTTP service eg;
========
<mx:Script>
         <![CDATA[
            public var whateverUserNameWasEntered:String;
             public var whateverUserPasswordEntered:String;
     public function onLoginSuccess():void
          whateverUserNameWasEntered:String = loginbox.text;
          whateverUserPasswordEntered:String = passwordbox.text;
          storeSessionStuff.send();
     ]]>
    </mx:Script>
<mx:HTTPService id="storeSessionStuff" showBusyCursor="true" method="POST" url="http://localhost/store.php" useProxy="false">
        <mx:request xmlns="">
          <username>
               {whateverUserNameWasEntered}
          </username>
          <password>
               {whateverUserPasswordEntered}
          </password>
        </mx:request>
    </mx:HTTPService>
========
direct it to the php file.....
<?php
session_start();
$_SESSION['username'] = $_POST['username'];
$_SESSION['password']   = $_POST['password'];
?>
Then, whenever you want to get the information out of the Session, send off another HTTP Service...;
<mx:HTTPService id="getSessionStuff" result="storeData(event)" showBusyCursor="true" method="POST" url="http://localhost/get.php" useProxy="false"/>
to the php file....
<?php
session_start();
print "<details><username>".$_SESSION['username']."</username><password>".$_SESSION['password'] ."</password></details>";
?>
which, you need a result function for:
<mx:Script>
         <![CDATA[
          private function storeData(evt:ResultEvent):void
                var username:String;
                var password: String;
               username = evt.result.details.username;
               password = evt.result.details.password;
      ]]>
</mx:Script>
ta daa
(if thats what you meant)

How to create a global variable in forms 6i

How to create a global variable in forms 6i

:GLOBAL.my_var := 15; Well, this statement is not correct! Global variables
stores a character string of up to 255 characters in
length. Thus, valid statement for Khurram example
is:
:GLOBAL.my_var := TO_CHAR(15);
or
:GLOBAL.my_var := '15';
But numeric values are implicitly converted by oracle so there's nothing in fact wrong with the statement...
:GLOBAL.my_var := 15;

How to get value for a global variable from an exel file?

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....

So that means they are already doing what I want anyway, right? If the reader only gets updated when the writer changes it, I can poll it as often as I want without increasing traffic, correct?

Can I Access the Value of a Global Variable in a Trigger

I'm using a Global variable in a Package which i use in the BIU Trigger to populate a column. After assigning the value for that global variable, I run an INSERT in the same package. But I find only the default value of the Global variable populated in the column. Can I use a Global Variable in a Trigger? Is there any way to put in a common value across all the tables in an application for all DMLs of a particular session?

Helios,
I'm already having the same setup mentioned in the thread. And I'm doing exactly whats given there. But the issue seems to be something different. I'm assigning the value to the Global Variable in the Package through Apex. Here's the Package Code:
CREATE OR REPLACE PACKAGE Schema1.SPMS_SECURITY_PKG
AS
X_app_user_id NUMBER DEFAULT -1;
FUNCTION USER_ID RETURN NUMBER;
END SPMS_SECURITY_PKG;
CREATE OR REPLACE PACKAGE BODY Schema1.spms_security_pkg
AS
FUNCTION user_id
RETURN NUMBER
IS
BEGIN
-- RAISE_APPLICATION_ERROR(-20001,'USER ID'||'*'||X_app_user_id);
RETURN NVL (x_app_user_id, -1);
-- RETURN NVL (sys_context('USERENV', 'CURRENT_USER'), -1);
EXCEPTION
WHEN OTHERS
THEN
RETURN -1;
END;
And Here is the Trigger Code:
CREATE OR REPLACE TRIGGER Schema1."USER_DETAILS_TRIGGER"
BEFORE INSERT OR UPDATE
ON PMS_SICAL.SPMS_USER_DETAILS REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
IF INSERTING
THEN
:NEW.created_by := spms_security_pkg.user_id;
:NEW.created_date := SYSDATE;
:NEW.START_DATE := SYSDATE;
ELSIF UPDATING
THEN
:NEW.updated_by := SPMS_SECURITY_PKG.X_app_user_id;--spms_security_pkg.user_id;
:NEW.updated_date := SYSDATE;
END IF;
END;
But I always get -1 in the both in the table after the DMLs.

Global variable in an event loop

Hi,
I have a global variable from one VI and want to read it in another VI but
only if the value has changed, i want to do it with an event case but it
doesn't do any thing when a read my Global variable in an event when the
value has changed?
Does anyone knows how to do this?
Best regards,
Thijs

You'll either need to generate a user event, or set the value using a value (signaling) property and let the "listener" create a dynamic value change event based on a reference to the indicator in use.
With user event:
Create a user event and give both the VI that is to react to a change event and the global (functional global) a reference to that event. Inside the global you check if the value differs from the previous one whenever it is written to, and if it is then fire the event.
