We heard from a customer who wanted to display a version number as a read-only production setting. During the build on the build server, this version number is added to the Production class. This works fine, and the Version is displayed in the Portal, but the customer wanted to write protect it, so the enduser can’t change it. The customer had defined the setting like this:

Property Version As %String;
Parameter SETTINGS = "Version:Info";

We advised the customer to define SETTINGS like this instead:

Parameter SETTINGS = "Version:Alerting:label"

Do to unforseen circumstances the Atelier build that was distributed with the Cache 2016.2 field test had certain incompatibilites which prevented it's effective use with the server that it was bundled with.

We are working on remediating this regretable situation and will provide a compatible Atelier in the 2016.2 field test refresh which is scheduled for today Monday, 1st of Februrary.

We sincerely apologize for any inconvenience so caused.

Creating an IDKEY with a chosen name

What do you do if you want to have the ID field have a meaningful name for your application?

Sometimes it comes to pass that when you're making a new table that you want to have the unique row identifier (a.k.a. IDKEY) to be a field that has a name that is meaningful for your data. Moreover, sometimes you want to set this value directly. Caché fully supports this functionality and it works Suppose you have a class Test.Kyle. The data will be stored like so:

^Test.Kyle(IDKEY)=$LB("",Field1,Field2,...,Fieldn)

Cache' databases as UNIX sparse files

Some third party backup products may by default restore CACHE.DAT files as UNIX sparse files when there are trailing zeroes in the backup file.

The support for sparse files vary from UNIX distribution and file system types. Sparse files attempt to use file system space more efficiently when blocks allocated to the file are mostly empty similar to thin-provisioned storage. The file system transparently converts metadata representing empty blocks into "real" blocks filled with zero bytes at runtime. The application is suppose to be unaware of this conversion.

The object and relational data models of the Caché database support three types of indexes, which are standard, bitmap, and bitslice. In addition to these three native types, developers can declare their own custom types of indexes and use them in any classes since version 2013.1. For example, iFind text indexes use that mechanism.

Oracle plans to deprecate the much-maligned Java browser plugin in JDK 9. For years, the bundled plugin put users at risk with its numerous security flaws. The web is clearly moving to a plugin-free state, which is a good direction.

If you are relying on the Java browser plugin, you should take a look at Java Web Start.

Here is the official blog post by Oracle:

This is a nice introductory explanation of MQTT that I thought would be of general interest. The technology used for the broker in this case is not that important as there are several brokers available.

At global summit we will be demonstrating ways to use MQTT with Ensemble to get information from the Internet of Things into your enterprise applications and business processes,

DecisionTree 
Is there someone that has developped a program in order to create a 
"decisiontree"? Depending The answer to a question leads to another question, and so on, 
and so on, and there is an option to return to another point in the decisiontree.

Best regards,

Simon.

p.s. I've already got something, but it's not workable. But to get an idea:

Often times support and sales engineers are asked about recent benchmark results on various platforms and large scale configurations. These will be made available here in the Developer Community in the "Documentation" section, and as an example here's a link to a recent Intel E7 v2 series processor benchmark.
