PCS Suggestions and Requests / WebEA link to diagram images.
« on: June 18, 2021, 11:26:21 am »
With PCS we now can use links to entities such as diagrams, projects, entities, etc, viz
Code: [Select]
https://example.com/WebEA?m=99&o=DB9A81E9-00C0-411d-8B89-B9A57F1FA4D7 to open WebEA in a browser.


Now, is to possible, or would it be a good idea, to have a URL that allows the diagram images to be accessed, and therefore embedded in a website?
e.g.
Code: [Select]
https://example.com/WebEA?m=99&o=DB9A81E9-00C0-411d-8B89-B9A57F1FA4D7&img=png

The main reason we moved to PCS was to replace the legacy licence server.
Fortunately you can use self signed certs Add Trust with a Certificate Authority (CA) | Enterprise Architect User Guide , or your organisation's Private CA.

I understand that HTTPS connections from EA to the repository through PCS are also supposed to be free, but if we don't have a licence token loaded they don't work for us. I'm hoping to hear back from support on this.

PCS General Board / Using PCS tokens
« on: June 04, 2021, 01:02:27 pm »

I asked support ...

it appears to me that one use can consume more than one token when using WebEA.
Id suggest that this is a bug when SSO is being used.
For example a user opens up several views of a model in separate browser tabs.
 
Support provided a good explanation of what is going on:



"Id suggest that this is a bug"
Unfortunately it is not, this behavior is a result of how browser to webserver interaction work.  When a browser opens a URL the hosting webserver allocates a unique session ID to that particular browser/URL combination, this session ID is the only form of identification the PCS has about a given 'user'. 
However you must remember that requests are stateless, ie from one request to the next the server doesn't know if the end user is 'logged in'. Some web application get around this limitation by including data in the URL which could uniquely identify a user to the webserver and then internally the webserver could store information about the current user, but we find such URLs messy, confusing and too easy to break if a user manually changes something.  Therefore the PCS keeps a track of users by session ID, but the main limitation with this approach is that users need to log out when they are finished, otherwise if they simply close the browser, then the token used is not released. 
In response to this situation the PCS will automatically release a token that hasn't been used after 30 minutes of inactivity.
 
 "For example a user opens up several views of a model in separate browser tabs."
 It is our understanding if multiple tabs, on the same browser, to the same URL are opened then the same session ID is used, which means the server has no way of identifying one tab from another and if a token has already been consumed by that session then all tabs could share the one token.  However if the same URL was opened in a different browser on the same client machine then yes, this would require another token because it would be using a different session ID.

The biggest "complain" I have is that the Floating License Server requires HTTPS and getting a certificate is non-trivial (but there are workarounds).
Actually I'm not fussed by the fact that you have to log in to the licence server in addition to EA.
The purpose for this is lost on me, and there is no option to turn authentication to the licence key server (LKS) off - work around is to publicise in the install instructions the LKS user id and password !

Are you referring to the instructions in the Sparx Systems website for WebEA?
yes, - Reuseable Asset Service (RAS) (sparxsystems.com) pdf

re you saying the instructions were clear but you didn't follow them or that the instructions were unclear?
Also, we're very interested in your journey with PCS and WebEA so please keep us informed!

The instructions may be clear, but they didn't work for me when I first attempted to follow them.
Due to other issues, as alluded to above, I haven't progressed with this.


The driver for this was replacing our licence server.
This then lets us use the PCS HTTPS server to connect to the models - also not requiring a licence (in theory), which requires less setup (e.g. providing direct access to the database), and is more resilient (over network disconnections).
So it is natural to explore WebEA and RAS

We access PCS using direct access for WebEA, Floating licence server, WebConfig, and HTTPS model access. Haven't managed to get RAS working for other reasons (including difficulty following instructions). We are using AD SSO.


Our problems seem to relate to WebEA where we are told that a token/licence is not required, but WebEA doesn't work without a token (support are looking at this).
That we run out of our two tokens (with only one user), we can't see who/where the tokens are being used, and there seems to be no mechanism to release them (also asked support to look at this). It looks a bit like PCS is counting each instance of a user (e.g. single user (SSO) opens two  browser WebEA sessions and uses two tokens!!!)

I think 255 is an EA limitation, its not in rfc4180 (ietf.org)

PCS Frequently Asked Questions / WebEA token usage
« on: June 02, 2021, 11:01:25 am »
We've just started our WebEA journey with Pro Cloud.
As a small team we've started with tow tokens.
We are using AAD SSO.

The documentation states ONE Token can be used to enable ONE web based user (WebEA,
but it seems that each browser tab takes up a token.
Have anyone observed anything similar?


And wait, there is more.
Is it possible to view who the tokens are allocated to, or to release them?

Yes, this is a known, and reported issue, see for example 8.0 diagram enhancements (sparxsystems.com)

as this is a user forum what you will get here is feedback and support on your suggestions.


Please use the Feature Request link found under support at the bottom of Forum pages to raise this officially with Sparx.
If you have a relationship with an EA vendor or EA trainer ask them to request these feature from Sparx, as their requests may have some weight
