I need to perform additional checks before Cache user logins (let's say in a terminal for simplicity) and allow access only to those, who passed them. How do I do it?

After reading about delegated authentication in docs I created this ZAUTHENTICATE routine:

ZAUTHENTICATE(ServiceName,Namespace,Username,Password,Credentials,Properties) PUBLIC { #include %occErrors #include %occStatus quit $$$ERROR($$$GeneralError,"No access") }

and set Password and Delegated as Allowed Authentication Methods   in %Service_Console (it's a windows install)

Expected result: no one can login via the terminal

I would like to know how to get the key value from a dropdownmenuitem placed on a navbar.

I have tried to get from onselect and onchange events of the template class, but it didn´t  work.

According to the snapshot attached I am trying to retrieve the values from 'action-1' and 'action-2'. 

I have attached a ZIP file with a snapshot which value I am trying to retrieve and example classes.

Thanks.

This advisory concerns the recently announced vulnerability CVE-2016-0800, aka DROWN, which is due to weaknesses in SSLv2. For more information, see https://drownattack.com.  This vulnerability may be relevant to InterSystems customers as InterSystems products have the capability to utilize SSLv2.

Hi,

Can a Cache Mirror be  used in the cloud ? (ie stand up a Primary and Backup member instances in a High Availability Cache Mirroring configuration) 

I'm investigating the validity of this configuration, because I was of the understanding that this may not possible due to these cloud servers not (typically) having fixed ip addresses, which interferes with the Virtual IP settings for the mirror set.

Is this correct, and if there are workarounds (like Load Balancing ?) can I have details on how this should be configured ?

I'm assuming other options like traditional Windows Clustering, or a

I just saw this new posting by Mike Kadow on the "Caché, Ensemble, DeepSee" Google Group announcing the availability of his new book, "Caché and MUMPS - Part II"

There's also more information about it at his site http://www.cosmumps.org/

I noticed a lot of sites these days support use of Gravatar user profile pictures so your profile picture can follow you around from site to site, could we support this here?

 http://en.gravatar.com/

Also there appears to be some HTML bug in the user profile edit page, when I click on the 'edit' tab I see options to edit the profile for a fraction of a second before this closes and I am unable to edit anything.

Hello good afternoon.
It is possible to change the background string " output " of the studio?
I would like to add a line in green or red line (TDD).

Most of my comments/contributions are personal, not reflecting the point-of-view of my current client. My WRC account is normally 'connected' with my clients email domain (e.g. csc.com).

I would like to set a personal account for DC so I can receive the digests in my own email box.

More sophisticated, I would like to use more then one email per account where I can specify on which address I want to receive DC digests

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.609.0.

This is a relatively light update with only a few dozen changes from the previous field test, spread out across all areas of the product.  Also, in a break from the recent past, this update doesn’t contain any new fixes to problems found in the field.

Please download the kit and give it a try; the latest field test of 2016.2 is available HERE.  And, as always, we welcome your feedback.

There have been a few use cases recently within InterSystems where we've needed to connect to Caché-based web services from PHP. The first of these was actually the Developer Community itself, which uses web services as part of Single Sign-On with other InterSystems sites/applications. The following example demonstrates how to connect to a Caché-based web service (particularly, the web service in the SAMPLES namespace) from PHP, using password authentication.

When developing or maintaining Caché Objects applications, or even ones written in plain COS code, it's sometimes useful to investigate dependencies. Yuzinji is a tool that analyzes the Caché class dictionary plus the COS code within methods and routines, then feeds its results into Structure101g Studio.

By doing this it becomes easy to ask questions such as "Who uses this piece of code?", getting the information in a format that is easy to explore further.

We are beginning a project to switch over to a differnt EMR for our inpatient system, and we are wondering if others out here have worked on a similar project and how did you handle your Ensemble environment?

Currently, we use one namespace for all of our HL7 interfaces. Has anyone used a separate namespace for a project to keep the build separate until go-live? What were the pros/cons for you using a different namespace? Or did you use one and what issues did you have because of it?

February 25, 2016 – Alert: Incorrect SQL Results InterSystems has corrected a defect that can cause incorrect results for certain SQL INSERT, UPDATE, and DELETE statements.

This defect is present only in Caché and Ensemble 2015.2 and HealthShare distributions based on them. The problem affects all platforms.

Incorrect results occur only when two or more of these statements are nested within each other.

The example below demonstrates one possible way for this problem to happen:

1. The class has an UPDATE trigger that uses embedded SQL to modify a table.

2. Because the SQL is embedded in the UPDATE

When my COS code is executing in a Caché process it might want to interact with the host operating system. For the purpose of this post I'm focusing on a Windows host, but much of it applies to other host OS platforms as well.

A common example of host OS interaction is when my process wants to read from or write to a file. What credentials will apply when Windows is checking whether or not to allow me access to the file?

To answer that we need to consider another question. How did our process start?

If we're in an interactive terminal session, perhaps we launched this from the Caché cube on the

Hi

In studio when I right-click a package there is no option to delete it.

Also how do I upload an image to this post without linking to an external site?

If you've got more than one developer on a project, do you each work in your own namespace? Or do you all use a common namespace?

Through my work at George James Software I have encountered many different Caché and Ensemble development setups. At risk of over-generalizing, the older and more established users of InterSystems technologies seem more likely to have all their developers working in a common namespace, whereas the newer 'converts' tend to favour giving each developer their own namespace.

I think it'd be interesting to discuss the pros and cons of these options, and to consider hybrid

Hello,

This package may be of interest...

I have programmed this over a hunch, in order to facilitate the retrieval of source code from a Caché installation. It makes use of the Java API provided by Caché.

Right now, I use it as a means to salvage sources in order to analyze them using the SonarQube plugin I develop for my employer. Unfortunately this plugin is not open source.

I am calling for help here, on two fronts:

• improve the code,
• obtain source samples to analyze!

RESTful API Call From Cache to Particle.io Electron

Tom Fitzgibbon | Multidata | 212-967-6700 x537 | tom@mul.com

Summary: Simple Blink Tutorial for Particle.io Electron Device from Cache

Electron device is a tiny ARM processor ($40-$60) that connects to Particle’s world wide leased 2G/3G network (about $3/mo) and runs off an included LiPo battery. Using Cache’s %Net.HttpRequest you can send/receive data, control hardware and read sensors.

Step by Step (about 1 hour)

1) Get the Electron from store.particle.io.

2) Set up the Electron from setup.particle.io.

3) Install an LED and resistor from setup

We have a situation where we want to detect and ignore documents/records at the earliest possible point based on certain criteria.  We have an existing "CDA Preprocessor" in the workflow which is an XSL transform.  This is what our contractors are planning to utilize to "filter" these documents.  This doesn't really make sense to me.  I see XSLT as a way to manipulate the contents of a document and filter certain peices of data.  In my brain, I would use an Ensemble business rule to detect the criteria and route the document as necessary.

Does anyone have any input on this?

I am pleased to announce the next 2016.2 field test kit, 2016.2.0.605.0.

There are about a hundred changes from the previous field test kit, including the following fixes to problems found by those using the kits in the field:

• DLP3516, which fixes a problem in the Demo.Document.Data.Loader class
• RJW2416, which fixes a problem with the telnet client disconnecting on Windows

One additional change of note: in this kit we have changed the on-disk format for DOCUMENT data.

The cdirectmgr utility will no longer be included with product distributions beginning with the Caché 2016.2 release . This was an older VB application (predating the Caché cube) which allowed users to define server connections for Visual M/Caché Direct applications. As VB 6 is no longer supported by Microsoft, we will no longer ship this component. The same functionality is already available from the cube utility.

It is also posted in Compatibility blog.

What is the recommended approach to handle the following scenario: Large number of HL7 messages are serviced via Ensemble.

Zen Reports has offered multiple choices for direct printing including use of Adobe Reader or Foxit reader. Recent changes in Windows 10 and in the readers themselves have made it no longer possible to invoke these readers from background processes in Windows 10 and all future versions. Because of this Zen Reports will no longer support printing with these tools on Windows 10.

Windows 10 support was added for 2015.1 and 2015.2.  On Windows 10, the only option for direct printing with Zen Reports will be Qoppa JPDFPrint.

Good morning people.
The use of TDD is currently being reference for software delivery more confiabilitade and quality.

At the company I work developing web applications , we create tests for method class in a deteminado package and running the steps that the documentation recommends:

1 export the tests classes to a predefined folder.
2- And running the test ( D ## class (% UnitTest.Manager ) .RunTest (,"/nodelete" )

It is a lot of work to do the export and run these tests would have a resource that we could only run the tests without the need for export ?

Is the default language (i.e., $$$DefaultLanguage, which is used as the basis for localization with $$$Text/etc. at compile time) always "en" for new Caché installations, or could it be different? How is this determined? I don't see an option to select a language during Caché installation.

Also, is there a supported/preferred API for setting the default language? Looking at %occMessages.inc, one option would be:

Set $$$DefaultLanguageNode = "en"

But I'd expect there to be a classmethod for this somewhere (and haven't managed to find it yet).

Hi Community!

I'm pleased to announce that  the winner of the Global Summit Free Registration Contest is...

I'm working on a proposal for a deployment tool development project and I was wondering if anyone had any experience with such a thing.  

We use Healthshare and implementations for new clients are tedius and lengthy.  Lots of ensemble service, registry value, lookup tables, namespaces and other things have to be created and configured. 

I would like to create a Zen or CSP page based deployment tool that can do all this with a few parameters and some custom code.

Has anyone done this?  What are some pitfalls you ran into?  Any unique ideas you included?  Other general thoughts?
