Caché

I am pleased to announce the third 2016.2 field test kit, 2016.2.0.590.0.

In the week since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.  Unlike the previous field test kit, though, in which the changes were distributed evenly over multiple areas and products, in this kit over half of the changes are associated just with Atelier.

Has anyone come up with a way to create a separate thread of processing that can achieve shared access to a set of objects created from the initials process?  The situation is this.  There is a large complex set of objects representing a business process.  Some of these objects are in-memory only.  The desire is to spin off a separate thread that could do some ancillary processing on this data set without slowing down the main process.   Any thoughts?

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.

I'm designing a workflow for PHR via FTP.  What I've done is create a single FTP adapter to pick up files from multiple customers.  A router then accesses a lookup table and determines if a particular customer is allowed to send a particular message type to the state.  If not, the message doesn't go out.  It seems like everyone is against this approach (other than my CEO, thankfully), including Intersystems:

I am pleased to announce the next in the series of 2016.2 field test kits, 2016.2.0.585.0.

In the two weeks since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.

In Atelier alone there were over a dozen changes including a fix for the incompatibility issue that Jamie Newton described in his posting of February 1.

In Caché major areas of focus include:

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)

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.

Is there a possibility to map a CSP page residing in namespace ABC to a namespace XYZ so you could access it as if executing from XYZ: http://localhost:57772/csp/xyz/MyPage.csp ? Some odd cocktail of web application and package mappings that could make this happen?

The idea is to keep the CSP page in sort of a read-only namespace that only contains code, with the data residing in another namespace. This works for zen pages, but not for CSP.

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:

Announcing Deltanji 6.0, the latest version of the well-respected George James Software source control product formerly known as VC/m.

Deltanji comes in four editions, including Solo which is quick to install on Caché or Ensemble (2009.1 or later), easy to get started with, and perpetually free.

Deltanji runs within the environment whose code it is managing, integrating closely with Studio and Portal, and storing code versions in a CACHE.DAT database.

I'm working on some custom utility functions that I can utilize in Business Rules as well as other places.  I saw this line in the docs:

For each function you wish to define, add a class method to your new function set class. There is no support for polymorphism, so to be precise, you must mark these class methods as final.

Hi,

I'm trying to create a Zen Report that, when rendered to PDF has a header on every page that includes some items from the group that I'm iterating over in the <body>.  I can't use <header> as that only displays once for each iteration, even if that spans more than one page, but <pageheader> seems to be independent of <body> so again doesn't work.

 

Cheers,

Steve.

New to CSP and Zen.  I've been going through tutorials and have made some progress.  Using the "Contacts" tutorial as an example, I'm trying to create a "ViewContact" page.  I want this to be linkable so I'm using URI Parameters, which I understand.  However, what I'm not sure about is how to retrieve a specific record.  Should I use a SQL statement?  If so, how?

I created a Zen page with a header. All is good. I then created a new Zen page and during the wizard specified that it was a "subclass of a template page". So now I have Class Custom.App.HomePage Extends Custom.App.TemplateMaster. If I visit HomePage.cls I see the header from the template. However, the HomePage class has no XData Contents section so I have no idea how to actually add content. I tried adding the section but once I do then I don't see the template content anymore.

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.

In the Caché Foundations course, students are learning about Caché Development and ObjectScript syntax at the same time. To help students complete the exercises, we provide an ObjectScript Quick Reference (aka "the Cheat Sheet").

It is not a reference for all of ObjectScript! It is a list of the ObjectScript commands and functions that students use during the course, along with common syntax for objects, collections, etc. It also contains some useful macros.
