General Board / What is a "property"?
« on: July 31, 2017, 11:42:24 pm »
Hello,

since several weeks I am asking myself the hell is a "property" when dropping a class element in a diagram.
When dropping a class element in a diagram a dialog appears asking of what kind the dropped element shall be created: Link, Instance, Child, Property.

Links, Instance and Child are perfectly clear.
I just don't know what a property might be.

Can anyone bring light into my darkness?
All explanations in the internet did not really help (maybe bad explained or I am too stupid for that).

Hello,
is it anyhow possible let EA create/remove tags based on the value of another tag?

Example:
I created an stereotype <<Signal>> (based on metaclass Interface).
A <<Signal>> will always have the tag "Conversion", which is an enum with "Analog" and "Linear" as selectable values.
I would no like to do EA the following magic:
 - If I select "Linear" two additional tags shall be added.
 - If I select "Analog": the two new tags should disappear, if existing.

Any idea how this can be realized?
Maybe UML profiles and stereotypes are the wrong way to do this. I appreciate any other idea.

General Board / Login to EA models - in some model Yes in some not
« on: December 14, 2016, 08:45:20 pm »
Hello,
we have
  • all models on a PostgreSQL server
  • all models configured with "Enable Security" and "Require User Lock to Edit"
  • every developer has its own "account" (user) configured in the models
Now we discover that on some models all users always get a login dialog ("Login to EA Repository" with UserID and Password) is shown, when opening the model.
After providing UserID and password and checking "Remember UserID" the models opens.
When reopening the model, after it has been closed, the dialog is shown again, with User Id already filled out.

On most other models this dialog does not appear.
As stated above: all models are configured identical.

Any idea what might cause some models always to ask for login but not in other models?

General Board / EA with repositories on PostgreSQL
« on: October 14, 2016, 11:40:42 pm »
Hello,
we are having all our EA models on a PostgreSQL server.
The server is configured to have a login role named "ea_user" that has superuser rights as role privileges.
EA uses "ea_user" and its configured password to login into the database(s).

I feel a little bit uncomfortable for a long time with the superuser rights to "ea_user".
What kind of access rights or privileges does a login role need as minimum for being able to do all possible tasks when EA connects to the database using that login role?

If reasonable possible I would like to cut the number of access rights of "ea_user" to the minimum.

General Board / Keystore service with AUTHMETHOD=AM_SSKSGROUP
« on: June 17, 2016, 04:32:46 pm »
Hello,

I am experimenting with the keystore service configured to authentication method AUTHMETHOD=AM_SSKSGROUP.
With the configuration seen below I found out the the UserName=g52873 corresponds to the Windows login name. But this way a "group" only consists of one user.
What I would like to have is a group consisting of several users
In our company we have of course no "shared logins", but individual Windows logins.

I would like to have a configuration allowing a list of users to use System Engineering Edition licenses.
Ideally all other users only get Corporate Edition licenses (we only have these two types of licenses in our key store.

Is the AUTHMETHOD=AM_SSKSGROUP the right way to achieve this or is this wrong?

My keystoreService.config file:
Code: [Select]
SERVER_PORT=7770
KEYSTORE_PATH=%SERVICE_PATH%\sskeys.dat
AUTHMETHOD=AM_SSKSGROUP
AUTHMETHOD_OPTIONS=%SERVICE_PATH%\keystoreservice.ssksgroupconfig
My keystoreservice.ssksgroupconfig:
Code: [Select]
GROUP
Name=SysML Users
UserName=g52873
Password=
ENTITLEMENT
Product=RealTimeSuite
Academic=false
END ENTITLEMENT
END GROUP

Bugs and Issues / EA forgets its configuration on floating license
« on: April 14, 2016, 04:51:38 pm »
Hello,

we are using the Sparx Keystore service for providing our floating licenses to the EA users.
From time to time all licenses are in use.
A user that starts EA, when all licenses are in use, gets an error message (as expected):
Quote
No available key for Enterprise Architect could be found.
Enter a key or connect to new keystore now?
[Yes]  [No]
After clicking on "No", because I know that no license is available, EA forgets that it had a "corporate floating" license configured previously.
When I "restart" EA afterwards the "License Management" dialog window appears where I can add or remove license keys.
In that dialog no license key is mentioned.

Can anybody confirm this behavior?
Why does EA forget about which license it has been configured?
Any idea how to prevent that EA forgets which license has been configured?

If anybody can confirm this I will report this as bug, as this is really annoying.
Many thanks.

General Board / Cloud Services: Storage location configuration
« on: December 15, 2015, 11:42:46 pm »
Hello,
where does Sparx Cloud Services store the configuration of the "Database Mangers", i.e. the list of the models that are exposed via the service and which models are read-only, etc.

I cannot find a file (with a recent date and time after a change of the configuration) and I cannot find anything in the registry.

General Board / How to use WAN Optimizer?
« on: November 17, 2015, 07:00:20 pm »
Hello,
some facts and background information:
  • Our company has two sites (Europe and India)
  • The central repository server for our EA models is located in Europe
  • The site in India is connected to our Europe LAN via VPN
  • Working in EA is awful slow for the guys in India :(
Our idea is to use the "WAN Optimizer" to speed up things for them.

For testing purposes I (sitting in Europe) installed the WAN Optimizer services on my laptop. I am not expexting speed improvements, I only want to be able to connect to our EA models using the WNA Optimizer as proxy instead of connecting to our SQL server directly.
  • The service is running on port 4242 (default)
  • In the WAN Optimizer Admin application I added a "Database Manager" using an already existing "connection string" provided by using an existing ODBC data source
How do I know the connection from EA to the model on the server goas "through" the WAN Optimizer?
What other changes do I have to do (e.g. change ODBC data source configuration)?

The user guide for WAN Optimizer does not mention anything. It only describes how to install, to configure and to troubleshoot.
I does not mention how to "use" it after installation and configuration.

General Board / EA and PostgreSQL x64
« on: November 03, 2015, 06:08:22 pm »
Hello,
I am currently "evaluating" if we can use EA (currently 12.0) with PostgreSQL 9.4 x64 as central repository server.

We are currently using EA with PostgreSQL 9.3 32 bit which work pretty fine.
On the clients we use psqlodbc 09.03 32 bit as ODBC driver.
EA clients run on Win 7 64 bit and PostgreSQL server runs on Windows 2012 R2.

When trying to connect to PostgreSQL 9.4 64 bit I face several issues:
  • Using psqlodbc 09.03 32 bit: EA 12 tries to open the database (all tables exist, but model is still empty):
    • EA tells the model is empty and ask to transfer a model into the database
    • When clicking "Yes" the next window that appears tells "EA has experienced a network error and will close down." :(
  • Using psqlodbc 09.03 64 bit:
    • EA does not even provide the database connection I configured for the test database :(
Does anybody have experience with EA and 64 bit PostgreSQL servers?
I would even appreciate an answer like "Hey dude, forget EA and PostgreSQL x64. This does not work. Use x86 and be happy."

General Board / Multi value/selection tagged value
« on: March 14, 2013, 09:03:09 pm »
Hello,

is it possible to create a tagged value that has has not only one value but allows selection of more than one value?

Background: In my software I have a central state machine (states: Init, Normal, Error). This state machine calls, or does not call, C-functions depending on the system state.
In my EA model I have functions (designed as ports of classes, implemented as C functions) that have to be called by the state machine. Due to other reasons I have to write the information in which state a function has to be called at the function and not at the state machine. One function has to be called in Init and Normal, the other function in all three states for example.

My idea was to use a tagged value based on an enum type that offers all possibles states. But instead of selecting only one of all possible states I would like to select more than one, or all states, or even none of them, ...

Maybe this idea is complete crap, therefore alternative ideas are welcome (note elements with list of states are not an option).

Many thanks.

General Board / Deletion of package not possible
« on: October 05, 2012, 06:11:01 pm »
Hello,

I wanted to delete a package that obviously does contains no more sub elements in the project browser.
We have enabled "Require User Lock to Edit" for the model.
I applied a user lock including child packages.

Now EA tells me in a message box "The selected item is currently locked, or contains items that are currently locked. It cannot be deleted this time."

There are really no more elements below this package visible in the project browser.
The project integrity check finds no problems.
Any ideas?

General Board / Cannot generate code of state machine
« on: September 20, 2012, 05:00:59 pm »
As described in the EA help system I created a state machine below a class.
When running the code generation (Java) only the class with a constructor and a finalize() method is generated. There are no methods which would implement the state machine.

I thought of creating an operation in the class an "linking" the state machine with this operation, but this 1. doesn't seem to work and 2. seems not to be the way how it shall be done.

The EA help system only tells that the state machine shall be below the class. And the help system presents example code that has been generated for a state machine. But the steps that lie between "state machine design" and "see generated code" is not described.

We are using EA 9.x Corporate Edition.
What did I make wrong? What did I miss to do? How can I generate the code of a state machine?

General Board / Embed or attach a document into model
« on: June 04, 2012, 06:27:02 pm »
Hello,

I searched a lot in the board but I could not find an answer to my question (neither a positive nor a negative answer):
How can I embed or attach a document into the model?

The document may be a Excel or Word document or anything else.
I am thinking a mechanism just like an email attachment. The file is stored inside the model and when double-clicking it opens in the intended tool for editing.

I an diagram I could set a hyper-link to an external storage location to the document. But as the storage location is not fixed a storage inside the model would be great.
All I can find is that I can embed RTF files, but I have an Excel document.

Any ideas or is it impossible?

Thanks a lot
Michael

General Board / Transparent background color for elements?
« on: January 21, 2012, 01:02:16 am »
Hello,
how can I set a transparent color (well, "no color") as background color for an element?

I have unintentionally set a background color for an Activity Partition. Now I should change it back to "transparent".
Somehow this seems not to be possible.

General Board / Cannot delete package
« on: December 07, 2011, 06:44:06 pm »
Hello,

I have a very strange thing here in my EA model.
In the project Browser I see an empty package that I want to delete. There is no diagram or sub-package visible in the project browser.

I locked the package and its parent package as I want to delete the empty package.
An error message is telling me:
Quote
The selected item is currently locked, or
contains items that are currently locked.

It can not be deleted at this time.
When locking the package I of course checked the "Include Child Packages" option.

Any idea what EA has done to my model, and how I can solve this?
