State diagram: how to start??

hi, i'm kinda new to UML diagramming and i hope you can help me in this...
i have already drawn the use case for my project scenario, a class diagram, sequence/collaboration, activity diagrams.
my problem is how do i start with a state diagram...i know it's about describing one (mebe more but usually one) object's behaviour throughout its lifetime, but how do i describe that in the diagram? do i need an object diagram for this (i didn't draw this diagram because i don't see any reason to yet)?
can u guys teach me how to draw step-by-step the state diagram plz? thx....

yes, activity diagrams and state diagrams are related.
While activity diagrams focus on the process.
I normally do a state diagram and then do an activity diagram for the tricky transitions, or processes during a state. Therefor I identify the necessary activity diagrams by looking at my state diagram, but I guess it works the other way round as well. Very often I end up having one part of the behaviour modeled as activity diagram and one part as state diagram
I find state diagram helpfull if an object has a certain behaviour at one point in time and a different behaviour at another time. Screenflow of a webapplication is one of my favorite examples. Each screen represents a state. Each link a transition. Even non technical users understand this very well.
If you want to display such a behaviour in an activity diagram you end up with tons of decissions, while a state diagram shows the possibilities very visual.
And no you don't have to have an object diagram before that. In some cases you will want to create one in the next step in order to clarify how an object 'looks like' when it is in a certain state.

How can I find and install the state diagram toolkit and how to--

Hi,
I like to do practice how to do coding by using state diagram toolkit. For that purpose I need to install that software. Can you please help me in this regard about how to get theat toolkit and install afterwards?
I have another question. By using VI snippets, I can extract the meaning of a particular VI/node/function block or whatever may be. Is there anyway to extract meaning in case that screenshot is not a snippet?
Also, can you tell me about how to start from scratch for using labview in building algorithm and coding? any resource?
Thank You.

The state diagram toolkit is an addon and it has license fees. It's install is available on the complete set of install disks.
There is no other way to extract code besides using snippets.
You can find lots of information here regarding LabVIEW training including online options. You can also go through the tutorials that ship with LabVIEW.

How to create state diagram (for state machine)

Hallo all.
In my previous visit here, i saw picture of state diagram (bubbles with connection),
How to create that in labview (if there is such option) ?
or, which other software create state diagram.
thanks

There is the State Diagram Toolkit (additional tool from NI for LabVIEW) with good interface and unreadable code
It gives you a State Diagram Editor at Functions palette.
It is very good tool for state diagram visualization, but readability of the code is controversial.
When you will get a clear picture of a diagram from State Diagram Editor, I suggest use classic state diagram pattern: case structure driven by typedef enum in while loop.

How to start and finish a transaction using EJB 3.0 in JDeveloper

Hello everybody!
Does anybody can explain how to start and finish a transaction using EJB 3.0. I need to start a transaction insert some information in some tables and if everything was fine commit the information.
I put the annotation @TransactionManagement(TransactionManagementType.BEAN) in my session bean and @Resource SessionContext ejbContext; but I don't what anything else I have to do.
Any help will be appreciate.

I tryied to use in the client the statement EntityTransaction transaction = myBean.getTransact(); but I receive the EJBException: Cannot use resource level transactions with a container managed EntityManager
I just need to start a transaction something like this: transaction.begin(); and finish the transaction, something like this: transaction.commit();
Does anybody can help?

Really stuck on how to start this program

Okay, I know I should be posting some code here and showing where I've started and such, but I'm pretty lost as to how to start this program. Here's the problem:
2. Making Change:
This application, named ChangeMaker, will take as input a product price and an amount paid,
both floating-point numbers representing euro and cent amounts. The application computes and prints the amount of change due the user, and also expresses the change amount in number of 2-euros, 1-euro, 20-cent, 10-cent, 5-cent, 2-cent, and1-cent coins.
(Assume no change is given in bills, only in coins.)
For example:
Enter product price: 2.32
Enter amount paid: 5.00
Your change is 2.68 euros
1 x 2 euro
3 x 20-cent
1 x 5 cent
1 x 2 cent
1 x 1 cent
You can assume that the amount paid is greater than the product price, and that both inputs are
"euro and cent" amounts: positive numbers with at most two decimal places.3
Now, I know how to print the line asking for product price and enter amount paid, but I cannot figure out how to set up the rest of the code when switching from american USD dollars/coins to euros. I looked up the conversions and they are just intimidating as all get out when trying to take the equivalency of euros to each dollar thats entered and then taking the rest of the USD remainders and represent that in USD coinage. >.< Help is much appreciated thank you.

For starters, just write the program without any currency information at all. (That is only flavour anyways.)
For example:
Enter product price: 2.32
Enter amount paid: 5.00
Your change is 2.68
1 x 2
3 x 0.2
1 x 0.05
1 x 0.02
1 x 0.01That deception would never fly in a Red State -- 20 cent piece? 2 cent piece? 2 dollar coin? All this smacks of Socialism!

Hi,
EDI
Electronic Data Interchange
Cross-company exchange of electronic data (for example business documents) between domestic and international business partners who use a variety of hardware, software, and communication services. The data involved is formatted according to predefined standards. In addition to this, SAP ALE technology is available for data exchange within a company.
Refer

EDI is nothing but Electronic data interchange. SAP will support EDI through Intermediate documents (IDOCS).
EDI (Electronic Document interchange) - EDI is the electronic exchange of business documents between the computer systems of business partners, using a standard format over a communication network.
EDI is also called paperless exchange.
Advantages:
Reduced Data entry errors
Reduced processing time
Availabilty of data in electonic form
Reduced paperwork
Reduced Cost
Reduced inventories and better planning
Standard means of communications
Better business process
EDI has two process
1. Outbound process
2. Inbound process
OP:
1.Application document is created.
2.IDOC is generated
3.IDoc is transferred from SAP to Operating system layer
4.Idoc is converted into EDI standards
5.Edi document is transmitted to the business partner
6.The Edi Subsystem report status to SAP
IP:
1.EDI transmission received
2.EDI document is converted into an IDOC
3.IDOC is transferred to the SAP layer
4.The application document is created
5.The application document can be viewed.
EDI FLOW :
Here is some thing which helps you and here the purchase order is taken as example too..
Electronic Data Interchange, or EDI, is the electronic exchange of business data. Using a standard format, EDI provides a method of transmitting business data from one computer to another, without the need to re-key data. This electronic link can result in more effective business transactions. With EDI, paper documents such as invoices can be replaced with electronic transmissions, thus time is saved, and the potential for error is minimized. Data can be exchanged at any time. Related business expenses, such as postage, printing, phone calls, and handling, can also be significantly reduced. EDI can aid in the support of manufacturing efforts, such as Just-in-Time and Third Party Warehousing, and financial efforts, such as Electronic Payments.
What parts of the business cycle can be supported by EDI?
Any business documents that are currently exchanged using paper can be converted to an EDI. Standards. Standards include ANSI X12 and XML/EDI are primarily used in the United States, while EDIFACT is used in Europe and Asia.
How does EDI get started?
EDI gets started when one company contacts another expressing interest in trading business documents electronically using Electronic Data Interchange. The two companies must first determine each other's EDI capabilities. If you do not already know your EDI capabilities, we have prepared a questionnaire to help you determine them. If you are already EDI capable, we will coordinate with your technical staff to determine a testing plan. Upon completion of testing the EDI documents, the appropriate business personnel will set a production start date to begin the exchange of EDI business data. If you are not EDI capable, we recommend you first obtain a commitment from your upper management. Your company will need to allocate resources and capital for software, hardware, testing, possible programming, and training.
What is the flow of EDI?
The flow of EDI depends on the sophistication of your systems and your EDI software. If you have internal purchasing/order entry systems, you will need interface programs that can extract and insert data out of and into these systems. EDI programs that interface with your internal systems are preferred over software that requires re-keying of data. Embassy Software specializes in seemless interface between EDI and your back office systems. Using a purchase order as an example of a business document your customer would send that PO electronically (850) to you. It could be sent either through a VAN (Value Added Network) or through an FTP server. You would take that 850 and convert it either into and ODBC database, a flat file or XML document to be imported into your Order System with the use of EDI Software such as PassportXchange.. Using EDI communication software, which is part of the PassportXchange package you would pull down data at set intervals from the VAN or FTP. These documents are then processed through EDI translation software and output to our order entry system. Finally, an EDI document called a functional acknowledgment (997) is sent to your customer.

As an aside, I will attempt to get rid of the READY deployment and deployment unit using deactive_deployment.sql
Now, if I attempt to use deactivate_execution.sql on any of the executions with status BUSY I get:
owner_owr@ORKDEV01> @deactivate_execution

ORA-06512: at "OWNER_OWR.WB_RT_EXECUTION", line 90
ORA-06512: at line 4
owner_owr@ORKDEV01>
So all the seems to remain is to use abort_exec_request.sql
This does the job, but the script itself hangs.
I think it has to do with the l_stream_id not being checked again after the initial IF. I think it should probably be part of the loop condition as it is again reset in the do_acks inside the loop.

State Diagram inside For Loop

I created a fairly involved for-loop with a flat sequence inside of it. The sequence had about four events that occured, and since it was kind of ugly, I thought I'd try the State Diagram Toolkit to replace the majority of the code. When I selected state diagram from the pallete, I was outside my for-loop. I drew up the various states/transitions, then realized that all this code needed to be inside the for-loop, but LV won't let me place state diagram-generated code inside the for-loop. I select everything related to the state diagram, but when I drag into the for-loop, only the comments come inside. I even tried generating a new for-loop and placing the state code inside. No luck. Any thoughts?

"Any thoughts?"
Yes but not any that will help.
1) Just modify your SD so that the exit loops back to the start while there are still things to do. Forget the outer For loop.
2) THe observations you reported are correct. When I first discovered these limitiations I said "That sucks!". Since then I have learned a bit and have grown to love the SDE.
The SDE is JUST (note: "just" is a four letter word around here ) a LV application that ofers a very limited GUI consisting of a picture control that then scripts (see LAVA Scripting Forum for info on scripting) your SD for you. SCripting LV code is no easy task. My experiments with scripting has shown that I have to keep a database of the contents of the LV diagram my code is developing to keep track of what is where. Well it turns out that the structure of a LV diagram is a lot like the structure of a FP in that you start with a "root" object either the FP or the BD. THe BD then has structures on it, like seq's loops etc with unlited nesting possible.
Now the SD created by the SDE is really just a fancy while loop with an case structure and code to support the driving enum. In order for you to be able to edit the SD the SDE needs to know what is htere already so it can show the diagram. It "KNOWS" by looking at its internal DB (I believe is stored inside of VI along with the enum.ctl) of the SD. To keep the DB updated, the SDE must be used to manipulate the SD.
Stop rambling and guessing and get to the point!
Moving the SD is just not supported by the SDE so it can not be done. To do so would require the SDE be able to "look" at the diagram, and repeat all of its work in the new location in the diagram.
BTW: Thank you for trying out and asking about the SDE. the more talking we do on this subject, the sooner the SDE will be updated.
My SDE wishlist (partial)
Add comments to diagram from SDE screen.
Add data structures to SD (shift registers) from SDE screen.
Add "un-do".
Select multiple objects on SDE screen and move or allign.
Select multiple objects on SDE screen and do "create sub-State-Diagram".
Allow watching more than one SDE in execution highlighting at the same time.

[SOLVED] openvpn issue: how to start service

Hi all,
I'm writing because I'm experiencing a problem while trying to start openvpn.
This morning I removed (i moved to .old) the rc.conf file and this means i'm using a full systemd configuration.
The problem is that I don't know how to start openvpn. yesterday I was doing:
/etc/rc.d/openvpn start
today I tried again but it does not find such file: it is no more there :S
i started through:
openvpn /etc/openvpn/vpnname.conf
and it seems to work...but is this the only way? It produces lot of output, should I redirect it? I think I can but it's not the optimal solution
I need to start the service manually.

State Diagram "Single Step" execution mode

Hello,
I am realtively new to LabView, at least the 8.0 version I am currently using. Used it when it first came out some xx years ago :-)
I am using the State Diagram Toolkit to create a test vi. I am able to create a SubVI of the test vi. I did **not** have to unlock the generated code to do this, and I could still open the subvi diagram in the State Editor later.
However, if I in the State Diagram Editor select "Execution Mode" to "Single Step", then LabView 8.0 crashes when I save the vi.
Please help me on this one, as I would like to explore using subvi's developed using the State Diagram Toolkit and the Single Step execution mode.
(I have indeed searched without finding the solutiion to this problem)
Also, if anyone have an examples on how to use a "Single Step" subvi developed with the State Editor Toolkit, I would appreciate this !
(Especially how to return the next state from the subvi and use it in the next call)
Tips and examples appreciated !

Hi,
A work around has been found for the issue. If after changing the state diagram type to single-step, you make a change to the block diagram then you can save with out a problem. There are two easy ways of doing this.
1. One is to add a new state to the state chart after changing the mode (this can be deleted after the save).
2. The other is adding a Boolean constant to the block diagram (which can also be deleted after the save). Adding a control on the front panel or moving a label in the block diagram is not enough.

Frode

State diagram toolkit

I am writing a program for an ATE product. I inherited a LV state machine design from an older piece of equipment that was written conventionally (without the diagram). I have started to design my new architecture using the State Diagram Toolkit. I like it! I'm assuming I can write/develop subvi's, too with state diagrams. Is this toolkit as truly automatic as it appears? Any drawbacks? Any tips? Anyone have any horror stories? Or cudos from the boss or customer?

Unlocking the diagram should only be done if an application needs to be modified and it will NEVER be edited using the SDE ever again.
It is possible to right click on the enum and edit the typedef.
When done save the control and you should be on your way.

How to start/ restart the service in visual admin of SAP WAS 6.4?

I have installed the sneak preview version of SAP NetWeaver WAS 6.4 for default Database MaxDB. While developing a simple application to manage simple database table citymaster with 2 columns in jsp I am getting error as
Exception e com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at : java.comp.
Looking at visual admin tool for WAS 6.4 all the entries are in color blue but the last entry for 'DATASOURCE' is in RED color where 'java.comp/env/JDBC/DATASOURCE' is the jndi reference created for default DataSource.
Can any one help me that why the last entry is in RED and it that say that some error has occured or that entry is not started then how to start that?
Please help....
