Author Topic: floating licence concurrent users and read-only (Read 5226 times)

kdr1066 · « **on:** October 24, 2005, 02:51:01 am »

We are considering which version of EA to purchase, Corporate seems the most suitable, but whether to use floating licences? I presume we'd need to install EA on the machines of all users*, but EA will only run if there is a licence key available? I don't suppose there's a way of providing read-only access if a licence key isn't available?

* I take it EA isn't a client/server app? Shared access to the project file or DB repository, but doesn't rely on a server executable to run?

EA_Lite provides read-only access See the Web Site for details...

HTH,

Thanks for replying.

So we'd need to install EA_Lite instead of EA for users that don't require write access. It isn't a case of 'sorry no licence key available, but you can have read-only access until a licence key is released'.

This would be a good enhancement for Sparx to consider: when a a shared key is unavailable allow EA to come up in View-Only mode.

We have a shared sever and so far, fortunatley, have never run out of keys. My concern is that a team need to view a model for a review and not have a license for them at that moment.

In the mean time, keep a copy of EA_Lite at the ready...

You CAN run both on the same machine, just be careful with install location and shortcuts.

Yes, I can, but in our organization we have the tool installed on a number of machines in conference rooms and terminal servers, and used off-and-on by about 50 developers of a wide spectrum of temperments. Getting them to bounce between the versions is a less-desirable option than to have the software come up in view mode.

Moreover maintaining multiple applications is someplace I don't want to go. Since EA is a non-standard (i.e. "non microsoft") application it is not supported by our infrastructure group. Adding support of another application to my unplanned responsibility list is something neither my boss nor I want to do.

Call me lazy, but the fix seems fairly straightforward...

I'm not disagreeing with you. It's just that the "mills of God grind slow, the mills of Sparx (appear) slower..."

Also, some changes appear conceptually easy, but due to prior architectural decisions, are actually harder than they should be. HINT: Why did Sparx go to the trouble of creating a new read-only application? Presumably, because they had to. Something in their internal architecture inhibited the "simple" suggestion you and I would have proposed.

It would be _very_ helpful to have a read-only access mode in the full EA version. It should (imho) be on a per project basis, so that it would allow me to give certain users (and groups) only read access in a designated project. There are so many permissons that can be granted (or revoked), why not a general "edit model" permission.

Kind regards

Can't you simply pass a recent r/o copy of the repository to those users? Or you use EA's security mechanism.

Hi Thomas

No, I don't think so: It's a repository-based shared model and some people (who do work with local EA fiels and the full version) should just read in the shared model.

The EA security meechanism doesn't offer a read.only setting, you can only use an SQL server read-only user, which then present the user with a great number of useless SQL server warnings and make EA almost unusable for him (in addition to making him/her feel themselves responsible for the errors, which they definitely aren't).

What do you think?

Thanks and kind reagrds
Hermann

Sounds reasonable. Another guess: could a versionig system be used to achieve what you want?
