General Board / Re: UML 2 Deployment Model

« on: July 02, 2008, 04:43:43 pm »

Sorry, I should have phrased my question better - interesting answer nonetheless.

While glancing through the UML 2.1 superstructure spec, I got the distinct impression that showing a component being <<deployed>> on a node is no longer fashionable(!)

It seemed to suggest than ONLY artifacts can be deployed and NOT components - but that artifacts could <<manifest>> components.

I was wondering if anyone had a more knowledgable reading of the spec?

General Board / UML 2 Deployment Model

Am I right in thinking that a deployment diagram should show artifacts (manifesting components) deployed on nodes?
As opposed to the traditional way of showing components directly deployed on nodes?
Thanks.

Thank you.
It's an excellent description - not a 'mass of verbiage'.

May I exemplify to aid understanding?

Would it be more inline with your definition to say <<server>> has tagged value "flavour=Windows|Linux|Unix". In my organisation we usually refer to 'Linux servers' or 'Unix servers' etc.

Further, my instance variables might include: OS, CPU, RAM, NIC...etc.

I could also use the same idea to classify network devices e.g. <<switch>> has tagged value "flavour=Ethernet|Fiber" etc.

In this case instance variables would include: Vendor, DTR etc.

Thanks again.

Thanks.
No, I'm not aware of the 'Set Run State'. I've looked it up and am a little confused by the difference between tagged values, and instance variables.

I would prefer to use tagged values as they are a UML Extension mechanism - however, maybe they're not appropriate for IT Infrastructure modeling.

If anyone has any suggestions to help explain the difference I would be most interested.

Thanks for the ideas gentlemen, your input is much appreciated.

My plan was to use a stereotype <<server>>, then use that on classes such as Linux/Windows/Unix, then use instance names to represent the machine names.

I'm really trying to figure out how difficult it would be to make minor changes if the number of servers were quite high (>200). I have to admit, EA is feeling just a little bit frustrating right now   !

General Board / Propogating tagged values...

« on: June 19, 2008, 01:17:15 am »

I have the following scenario:
In my profile, I've created tagged values on a stereotype and imported my profile into another model.

In the model, I've created a Node, assigned the stereotype to that Node and created instances of that Node.
For example, I've created a stereotype <<server>> with tagged value "OS". In my model, I've created Node 'Unix Server' and Node instances called 'server1', 'server2'...'server n'.

Now, I decide all the servers are Solaris - so I set the tagged value "OS=Solaris" on the Node 'Unix Server'.

Can I get that tagged value to propagate down to all EXISTING Node instances 'server1', 'server2'....'server n'?

I can't set a default value on the stereotypes' tagged value because I also want to create Windows Server and Linux Server Nodes.

Thanks.

General Board / Tagged Values not generated in html

« on: June 19, 2008, 06:43:09 pm »

I've created a profile with stereotypes and tagged values and used the profile in a model.
Having set the tagged values in the model, I generate an HTML Report. However, only a few of the tagged values appear agains their parent instances - the vast majority aren't in the report.
I've not yet spotted a pattern regarding what appears or doesn't appear.

I'm not sure if I've missed a step during the generation, or if it's an issue I should report.

Any guidance is much appreciated.

Thanks.

Thanks for the pointer...it's done.

I'll add this in-case it helps someone else.
Any stereotype defined in a profile that is derived from Metaclass Device will not sync when you alter tagged values.
Use the metaclass Node instead - this does appear to sync.

Sorry, I've answered my own question.
I've found that each stereotype in the Resources view has a 'sync' menu.
However, I've added a 'test' tagged value to the profile and when I press 'sync' nothing happens, and the existing instances are still missing the tag.

Are there any obvious reasons for this (e.g. I've regenerated something through ignorance)?

General Board / Profiles and tagged values...

« on: June 18, 2008, 07:58:46 pm »

I've created a profile with stereotypes and tagged values (e.g. <<server>>  with tags CPU, RAM etc.).
I can import the profile into my model and use the stereotypes.
However, if I open the profile and add a new tagged value to the stereotype (e.g. HDD), and re-import into my project - any existing instances of server are not updated. i.e. only new instances have the additional HDD tagged value.

Is there a way to get existing to update themselves with the new tagged value?

General Board / Default icon for stereotypes...

« on: June 18, 2008, 02:41:55 am »

I'm learning EA and am wondering about the following.

I'm creating a profile. I want to create e.g. a server stereotype - and to associate a .emf with that stereotype.
Of course, when I import the stereotype into a model - I want to see my server icon.

Is this possible?

Thanks.

Yes, I see your point.

My other question is more 'after the fact'.
Once the instance model has been manually completed, is there any way I could potentially (e.g.) run a script or something, to ensure the instance diagram is consistent with the class diagram?

Thanks

General Board / Deployment Diagrams

« on: June 01, 2008, 08:22:21 pm »

I'm a beginner to EA and would like to know if the following is possible or even make sense in UML/EA?

I've created a Device Node (Linux Server) with a nested Execution Environment (Application Server).
On another diagram, I Ctrl drag the Device Node to create an instance. However, I would like a nested instance of the Execution Environment to be shown as well.

Can this be done automatically, or do I have to re-create the child Nodes in the instance diagram manually?

Thanks
