How do Business Spaces work?

MichaelQ

I'm getting tangled up and bamboozled here....
I think this is what happened....
(Business Space = 'BS')

I created a BS 'test' and everything worked OK. I was able to add the sample Apps and a new one called 'rap'.
But it seems Sample apps can also be loaded directly eg if I load 'rap' the other apps that were in the 'test ' BS are not loaded.
Are the Sample Apps also BSs? If so, in the case of the 'test' BS, how can it contain the other sample BSs?

Then I decided to export a BSV of my app and test re-import.
It re-imported into a new BS inside 'test' BS and appeared OK alongside the others.

Then I made the mistake of deleting the 'test' BS and now my admin user credentials seem to be screwed up.

When I log in directly to 'rap' in the Configurator and then try to test the app I get the following message: "Exception changing status of the business space version Aware IM server encountered the following error. Resource provider not set for loading of binary resources."

I'm also getting:
"Exception changing status of the business space version Aware IM server encountered the following error. Error reading business object. Table 'basdb.test_regularuser'doesn't exist."

=====
I am obviously missing something here and the manual doesn't seem clear about this. Perhaps there is a distinction between BS and App? Is there a "Global" BS which contains users for all the others?

I'd appreciate someone giving me a clue about how BSs work and pointing me in the right direction.
Many Thanks.

ps: I set "Allocate Separate Database" for most of the BSs.

I don't have a direct answer to your question, since I'm also unclear how things exactly work internally, but I can throw in a couple of suggestions to stay in line.

Let's say you're starting with a fresh installation. The very first time Aware asks you for creating a Default Application. That seems to be the name for a container for ALL other BS that we create. I name it "Default App" and I do NOT use it for anything. Although it is a BS, but I just leave it alone. I let Aware do it's thing and create "Default App". I'd exit and re-enter into aware with

Business Space: DefaultApp
User ID: admin
Password: password

Once I'm in, I then right click on the root of the tree (Business Space) and select "New" and I create a new Business Space that I plan to work on. I can add as many BS as I want to this container, as long as I don't mess with the "DefaultApp" BS and I add it to the top root. This has worked for me without any issues.

Hope this helps!

Thanks Ben.

Yes that's exactly how I was using it. (But we can also log in to each BS space individually). I don't understand how or where the configurator user/password is stored and how this all works. Very puzzling.

But what happens if we have accidentally messed with Default app or it has got corrupted?
I'm assuming this will require a complete reinstall and then an import of my particular test BSV.
I'm testing this solution now by creating a new install on AWS, but I'd still like to feel confident that I could fix the installation on my laptop.

Of course it is really important to understand what's going on behind the scenes so that if this happens on a production server where a full reinstall is not so easy, one can figure out how to repair this.

Perhaps support can outline how this works or point to the information in the documentation?

For unknown reason, without doing anything different, I've encountered twice where I would exit Aware's editor and when I would try to re-enter, I would get error regarding Invalid credentials or other exxception errors, and I go no longer get in. I literally had to re-install Aware again and import my BSV in. I constantly (before exiting) export my BSV, in case I can't get in.
So yes, this is one area that is totally a "Black Box" to me. I wish we had more info how to deal/resolve when this system crashes or gets corrupted. What if that was on production server?

Somehow you have managed to screw up your database - it's unclear why and how. It normally doesn't happen and the system prevents you normally from screwing up. But accidents do happen sometimes.

This is why you need to always keep your latest BSV file somewhere safe. And in production you should ALWAYS keep your latest database backup especially if you are developing using the production version (and the system warns you three thousand times about it when you try to publish).

If you are evaluating you should just re-install.

Thanks Support.
I tried to reinstall but when I try to start AIM I get the error message below.
I even reverted to Derby db but still no go.

Thanks Mark for sorting this out for me.
