Re your Atelier issue, does the "Configure server" link lead you to somewhere you can test the connection? Make sure that your Atelier connection is pointing to the port that your Cache Portal also goes to, and not to the port that your Cache Studio uses. That was an early gotcha for me in Atelier.

The Cache username that you connect with might not have enough privileges. One way to determine if this is you problem is to grant the user the %All role temporarily.

A few more caveats:

  • It's not that you can't use the READ command, but that the command completes immediately with emptystring, i.e. "". So beware of running certain command-line utilities. For example, if you connect Studio to %SYS and D ^LOCKTAB in the Output pane you're trapped in an endless loop and have to terminate your Studio.
  • If anything you run releases all locks with an argumentless LOCK command, any Studio locks will also be gone. I've sometimes wished COS allowed us to protect the locks of our process in the same way as we can NEW our local variables.
  • Issuing the H or HALT command is a surefire way of ending your Studion session.

If you're planning to develop on a later version than you deploy onto, beware the occasional gotcha. For example http://docs.intersystems.com/ens20151/csp/docbook/DocBook.UI.Page.cls?KEY=EGRN_compatibility#EGRN_compatibility_hl7schemas identifies an issue with trying to import a 2014.1+ schema into a pre-2014.1 environment. I have seen at least one Ensemble site mangle their production by exporting a schema from 2014.1 or later and then importing it into an earlier version.

Has any information about system methods reached the documentation yet? On my 2016.2 FT (build 585) Documatic shows the methods of %Library.Object in a new section headed "SystemMethods" and summarized in a table titled "System Methods". The methods start with keywords systemmethod and systemclassmethod but a DocBook search on either of those terms doesn't get me any extra information.

Also, in Stefan's article the section about system methods says that the "live in a separate namespace" (my emphasis). I don't think he means namespace in the sense of %SYS, SAMPLES, USER etc, but rather that your own method called "new" can coexist with the systemmethod called "new".

What's the right support channel to use for the cloud-based Atelier FT server? I log in at https://wrc.intersystems.com/wrc/BetaPortalCloud.csp and click the "Launch Server" button. The button disappears immediately and is replaced by text saying "Your Atelier Server has been launched,
it will run for the next (expired)." and when I click on the xxx-.isc.appsembler.com/csp/sys/UtilHome.csp URL I am offered I get a page reading "
