Initialization of global/scope variables ONLY through ASSIGN?

Is it only possible to initialize global resp. scope variables through an explicit ASSIGN?
Or can I place e.g. a value="...." attribute inside the BPEL source code at the variable declaration
to initialize it directly?
Or even better: can I init the variable through JDeveloper GUI?

I looked this up on Oracle Support and there was one thread that it said that it could be resolved with a 11.1.1.6. to 11.1.1.6.2 patch update.
We have one test environment on 11.1.1.6.6 to which we have uploaded the RPD to receive the same error, although it now additionally indicated a "Blacklisted Connection Pool". Here are the error details:\
[2013-01-22T00:30:32.000-08:00] [OracleBIServerComponent] [ERROR:1] [] [] [ecid: 004osJjn__ADCgH_qt0FyY0006Py000000] [tid: e9c8a950] [nQSError: 17014] Could not connect to Oracle database. [[

This is the way I have defined the DSN for the OCI 10g/ 11g within the RPD connection pool:
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.53.36.93)(PORT=1541))(ADDRESS=(PROTOCOL=TCP)(HOST=10.53.36.94)(PORT=1541))(ADDRESS=(PROTOCOL=TCP)(HOST=10.53.36.95)(PORT=1541))(ADDRESS=(PROTOCOL=TCP)(HOST=10.53.36.96)(PORT=1541))(LOAD_BALANCE=yes)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=a.b.c)))
My next test would be to individually test each host and see which one causes it to error out.
Any insights of what I could look to additionally do?
PS: The DBA is yet to get back with the exact version of the Oracle 11g DB but it is greater than 11.1.0.7 since that was the version they were running 6 months back and might have upgraded.

GetVariableData() usage with global-scope primitives (BPEL 2.0)

My composite has a global scope variable named "length" that is defined as an integer. When I attempt to access it at the same scope from an embedded Java using getVariableData() I get a funky error.
My variable definition is:
<variable name="length" type="xsd:integer"/>
And my embedded Java looks like this:
try {
int pwdLen = getVariableData("length");
}catch (Exception e) {
addAuditTrailEntry("Exception occured in length: " + e);
Can anyone see why this isn't working?

getVariableData() doesn't return int. The following works:
try {
int pwdLen = Integer.parseInt((String)getVariableData("length"));
}catch (Exception e) {
addAuditTrailEntry("Exception occured in length: " + e);

Persisting variables to global scope (M spec's 'shared' keyword?)

Hi,
I wanted to declare multiple variables I'd like to reuse in a query, and be able to keep them in scope afterwards for use in other queries. The alternative of redeclaring them in each query separately would seem tedious, while individual queries can also
only return one variable each (be it a table/list).
I read in the M formula specification that it should be possible to global-scope a variable using the 'shared' keyword, though apparently this was only for use in the 'sections' part of the M specification unimplemented in Power Query itself. Am I missing
something? Might there be some other way to persist a variable to the shared (global) scope from within a query?

Thank you for the further clarification on sections; I didn't really know they are still kind of there in the background.
Reconsidering, I suppose my perceived issue isn't really so bad. I think what I wanted (using M functions from text files like an external library) is pretty well doable, so I've Github'd (https://github.com/tycho01/pquery) what I have for others to try;
perhaps that may help illustrate my use case a bit. I think I'm actually satisfied now, though I may as well explain better what I was trying.
What I'm imagining (as an analogy to my experience with Excel VBA) is basically having a larger library of user defined M functions to flesh out the built-in ones, with smaller functions for relatively basic tasks, and mid-level functions building upon those
and upon each other.
Considering the (current) effort in adding a bunch of functions to different workbooks, not to mention edit syncing concerns, keeping such all-purpose functions separate from individual workbooks (in analogy to VBA's 'personal' workbook) would seem sensible.
If that were to work out, eventually it may be preferable if things were to 'just work', in terms of all functions being in scope, so each such library function could freely call other such library functions.
At present, if you load multiple functions through Expression.Evaluate(), possible in batch through lists/records as you mentioned, they will all be available in the original scope.
However, with no effective way to pass this around (unless environments?), the loaded functions will not know of each other though. What I do now is to explicitly load used library functions in each function where they are needed. Under this limitation of losing
scope between functions, it might be ideal to have all available functions loaded only once.
Reloading in batch (i.e. load the whole library rather than the parts needed) within every new function scope may become less desirable in terms of unnecessary overhead.
I suppose for the most part my scenario is still largely hypothetical though, so I might as well try and see if the general idea would take off in the PQ community for now. In either case, thank you for your replies.

Final variable with global scope?

Hi,
We are building a multi threaded server application. We have the need to use some constants (finals) across mutliple classes/threads. Is there a way to create a list of final vars with a global scope? We've considerd a class with static vars, but that would imply using the classname when using the vars. e.g. GlobalClass.VARNAME. We would like to use just VARNAME. Is there a way to do this?

Hi,
Here is the thread that addresses the same issue as yours.

Method Scope variables controls Multi-Threading !

Hye there Experts !
First, let me thank you all for such a brain-stuff sharing around; feel nice to be a part here.
While browsing through the below article, found something confusing...kindly clarify.
http://www.javaworld.com/javaworld/jw-07-2004/jw-0712-threadsafe.html?page=1
Extract from the above discussion I understand :
when a variable is moved to method scope instead of instance scope, synchronization is achieved.
How is this true for servlets ???
Method scope variables are available only during method call I think...here, since this is a servlet, there will be only one instance and if many (lets say 10) requests hits this servlet object, all these threads will read same counter as all of them enter into this only one method of this object,
so...this should be still not thread safe I guess.
I didn't want to execute and see results of this code, but I am trying to understand the key at first.
Please guide me before brain blows... :-)
Would also appreciate any references that really says true things about
'synchronization for enterprize (handle huge requests) web apps - technques for servlets and any other stuff'
Thanks again guys, have a wonderful time.

feel nice to be a part here.Welcome to the mad-house ;-)
Method scope variables are available only during method callWARNING: I'm no guru, so this may be misleading or just plain wrong.. but as I understand it:
Yep a "local" variable exists only the context of the execution of it's containing method... so a local variable is implicitly bound to the thread that created it (by invoking the method in which the local is declared)... a local variable can't be accessed directly by another thread simply because the other thread has no access-path to the variable (you can't expose a local through getters & setters)... hence locals are thread safe.
The important bit is that it's the thread which "owns" the local variable... not the declaring method... if the method is executed concurrently by two threads, each thread will have its own private copy of all the local variables.
One other question though: are locals in static methods still thread safe? I'm not sure.

Dealing with a turn based application with using a global static variable

Hi there. I read some articles about JavaFX concurrency,so as a newbie i have to practice on it. Now i'm trying to implement a turn based application that can be played among 3-6 players. Moreover, i use a scene imported from a .fxml file and i have to update it correctly depends on some calculations of each thread (in other word players ). My main issue is, i don't wanna use a while loop which checks the state of game like;
while( GameState != State.GAME_OVER ){
 currentPlayer = GameBoard.getNextPlayer();
 // do some actions,calculations etc.
So, i want to use worker threads instead of this while loop. I guess using Service class for iterating and assigning the next player will be suitable instead of using the while loop and Tasks for doing each player's calculation,or waiting for some responses from Human players on UI based,however, i'm struggling with two problems.
There should a global static variable ( like GameState which is an Enumarator ) determines the state of the game,so it should be updated and should be checked by each turn. Is there any way to do this ?
How can i get rid off this while loop ?
I will appreciate for every answer. Thanks anyway.

It shouldn't make too much difference. The basic idea is that you have a model class representing your game state (the Game class in jsmith's example). When a player makes a move, you update the state of the game. Since this will result in changes to the UI, this update should be performed on the FX Application Thread.
If the player making the move is a human player, the move will likely be made by a user action (button press or mouse click, etc); this will be handled on the FX Application thread anyway.
When the state of the game changes so it is the turn of an "artificial" player to make a move, have the object representing the artificial player calculate its next move, and then update the game state. Since this is a response to the game state changing (it's now the turn of the artificial player), this will also be on the FX Application Thread.
The only (slight) complexity comes if the calculation of the move for the artificial player takes a long time. You don't want to perform this long running calculation on the FX Application Thread. The cleanest way to manage this is to launch a Task which calculates the desired move, and then updates the game state when the move is ready. So, something like this:
GameState game = ... ;
// UI is bound to the game state.
ExecutorService executorService = ... ;
final Player currentPlayer = game.getCurrentPlayer() ;
final Task<Move> calculateMoveTask = new Task<Move>() {
 @Override
 public Move call() {
 Move move = // compute next move...
 return move ;
calculateMoveTask.setOnSucceeded(new EventHandler<WorkerStateEvent>() {
 @Override
 public void handle(WorkerStateEvent event) {
 gameState.makeMove(currentPlayer, calculateMoveTask.getValue());
executorService.submit(calculateMoveTask);
If you're doing more threading than that, you're probably doing it wrong... . There should also be no need for anything to be held as a "global" static variable (the idea above is the only structural modification you need to the example posted by jsmith).

Resolving session scoped component in global scope component.

Hi,
I am implementing batch process and i am need to resolve session scoped component in global scoped component.
In global scope component (one of the component referred by my scheduler which also in global scope as usual) and i need to resolve session scoped "/atg/epub/workflow/WorkflowView" component in my scheduler.
I tried all possibilities but nothing worked out. I do not have access to current request, because its batch process. following ways i tried,
1. getResolveName("/atg/epub/workflow/WorkflowView") method of GenericService which is extended by my global scope component -- This returns null.
2. Tried to get the current request on ServletUtils to use resolveName() method on request.
ServletUtlis.getCurrentRequest() - This returns null as expected.
Is there any way to resolve session scoped component in global scope component. Thanks in advance.
Edited by: 938890 on Jun 30, 2012 4:59 AM

Try below :
If you want to resolve the name of a Nucleus component from Java code that is not itself a Nucleus service, you must first initialize Nucleus with this construct:
Nucleus.getGlobalNucleus().resolveName("target component")
where target component is the name of the component you are looking up. Note that this construct works only for components with global scope.
You can also resolve names of Nucleus components using the Java Naming and Directory Interface (JNDI). The following example shows how you can use JNDI to access the Scheduler component:
String jndiName = "dynamo:/atg/dynamo/service/Scheduler";
Context ctx = new javax.naming.InitialContext ();
Scheduler s = (Scheduler) ctx.lookup (jndiName);

Global Counter Variable - Graphical Mapping

Hi there.
Can anybody help with implementing a global counter variable in the graphical mapping please.
I am trying to populate the "SEGMENT" field of an IDoc with the correct sequence, i.e. add 1 for each new segment. The IDoc has several segments, most of which are embedded. I have tried using the "counter" function but this seems to reset back to one for each instance of it being called.
I would appreciate any pointers.
Thank you.

Comma problem with global string variable

Hi,
I'm fiighting with comma problem for global string variable. I've on page string for example "7nndqrr52vzyb,0" and by dynamic column link I'm assigning this string to global variable. Then I'm trying to display value of that global variable on another page but I see only string till comma, nothings more. I'm not sure what I'm doing wrong because when I'm trying to assign that value normally by computation process as a constant value is fine and see on another page correct string. I'll be really glad for help.
Thanks
Cheers,
Mariusz

When it tries to display the string, it sees the comma and wants to believe the string is terminated. You could escape the , in the string or replace it with a different character..

if you can detail this +"If the managed bean uses a HashMap to store values then the bean itself can be used to expose an interface for all of what you want it to do. So its an architecture decision to make (which you should do when designing the application)"+
As of now what i am doing is

 logger.info("inside printMemoryVariables");
 AdfFacesContext adfFacesCtx = AdfFacesContext.getCurrentInstance();
 // get the PageFlowScope Params

 //iterate through HashMap values iterator
 while(itrValues.hasNext() && itrKeys.hasNext()){

WEBI prompt based on bex variable suppress not assigned hashtag value in LOV

Hi,
is it possible to suppress the "Not assigned (#)" value from the list of values in a webi prompt based on a bex variable?
This "Not assigned" value is something BW specific, BW adds this to each characteristic automatically?!
WEBI:
RSRT:
It needs to work in WEBI, not only in RSRT, and the filtering of data still needs to work.
For rsrt it works, when you exclude the not assigned value in "Filter > Characteristic Restrictions" and use the bex variable in/through "Filter > Default Values", but this does not work in WEBI, because the BEX Query Data is not filtered on the in the prompt selected value.
Thanks.
Regards
David

Thanks David for a quick reply !
I could manage to avoid # values in WebI prompt using BAdI implementation, here is the brief:
Problem:
WebI report prompt (which shows BEx variable) list of values shows blanks or # . Rrequirement was to avoid these blanks or #
Environment:
BW 7.3
BO 4.0
BW Cube > BEx Query > OLAP Connection > WebI report
Solution:
InfoObject Level1 in BW had # values in masterdata, this could not be deleted since it was in use with other Cubes.
Vaurable Var_Level1 displays # when pressed F4 running BEx query and in list of values in WebI report prompt.
I implemented BAdI on Level1 info object and variable Var_Level1.
Steps to implement BAdI are as in following link

Application scope variables ... an easier way or not ?

Instead of sharing application scope variables through the
 servletContext()/application I am using a normal singleton class (or maybe
 static class) to share all my application varaiable. It works fine and it
 takes a lot less code to write.
 It seamed logical to do this a static classes or singletons are shared
 within a single servletContext/application (which there seems to be only one
 per WL instance anyway). (singleton is quite nice pattern coz. all
 jsp:useBeans with the application scope are by definition singletons)
 Has anoyne tried something similar or maybe know of the problem with this
 approach. I assume that server will never reinitialise application level
 variables ...... hope the assumption is correct. ....


When you specify application scope, the JSP stores/retrieves the value
 into/from the servlet context. You may already know this, but it sounded
 like what you thought you were somehow avoiding.

Global PATH variables?[solved]

How do i set global path variables in archlinux??
I need to do this because ie, I am using gmrun, and I just installed xarchiver. But gmrun cant find xarchiver since it is located in /opt/xfce4/bin/.. I can append this to my PATH in .zshrc/ .bashrc file, but this only helps when i run it through the terminal.
I want to also be able to have a global alias file, to run the alias xterm = 'xterm -bg black -fg white' through gmrun.
Couldnt find any documents on how this works in archlinux.
Last edited by jinn (2007-02-04 10:56:40)

For the path, run 'bash /etc/profile' to update the path for the current terminal. You can also logout then relogin to set them for the whole session. No files needs changing.
For the alias, create a 'etc/profile.d/alias.sh' file. add the alias in it and give it executable permission. For the change to take effect, you'll need to run 'bash /etc/profile' or logout/relogin.

Elements that need to be paid only through Cheque

Hi all,
I'm on R12 International HRMS.
I have a few Elements that need to be paid only through Cheque.
These elements are run separately as a quick pay or by selecting an element set and assignment set and run the payroll process separately.
What is the best approach to go about this requirement.
The default payment type defined is Cash Type.
How can I make sure the payment for these element is always Cheque
And also how do I customize the Cheque Writer(Generic) Process to include my design of the cheque.
Thanks

If you are using Assignment set , run the payroll using assignment set and after that run cheque writer and make sure u did not add
any bank details to him , it will pay by cheque as per my understanding
