NewBie's Corner Session 16 Introduction to New Concepts

NewBie's Corner Session 16 Introduction to New Concepts

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

A number of new concepts are introduced in this session that will be developed more fully in subsequent sessions. It is necessary to at least introduce these concepts here because they are all interrelated.

Older style of MUMPS Programming

A routine has access to all the variables it creates. When Routine-A calls Routine-B and Routine-B calls Routine-C, and so forth, this is known as a Call Stack.

REST and IO redirection

Problem: I have a REST broker, and if I hit a code block, which does IO redirection, the REST reply becomes broken in one of the following ways:

  • Binary output
  • No output
  • First 4096 characters of the reply are missing

Consider the following REST broker:

Class A.REST Extends %CSP.REST
{

XData UrlMap
{
<Routes>
<Route Url="/Test/:redirect" Method="GET" Call="Test"/>
 </Routes>
}

ClassMethod Test(Redirect As %Boolean = {$$$YES}) As %Status
{
    Set str = $TR($J("",4098)," ","1") // Get a string with the length of 4098 symbols
    
    Do:Redirect .

Credentials in Ensemble - working in other namespaces

Hello community,

I have productions running in several different namespaces.  They all use a common credentials ID for sending email, which is set up in only one of the namespaces.  The documentation says that credentials are entered by namespace.  When I ran a production in a second namespace, the error log said that credentials were not found (expected), but later attempts to send a file thorugh the production did successfully send an email.  I'm wondering if Ensemble is able to look in other namespaces for the same credentials ID?

Problem in the Property parameters (DISPLAYLIST | VALUELIST) [ SOLVED ]

I'm with a problem in a property, where she has two parameters that conflict, DISPLAYLIST and VALUELIST.

In screen when I'll go to set value in the field, the CACHE transform internally the property of LOGICAL to DISPLAY with propertynameLogicalToDisplay(propertyname), far so good.

My problem is in the property, why, by default she send the value as DISPLAYLIST, in hour of transformation as the value is DISPLAY MODE the error occurs.

How I do to that default value be VALUELIST and not DISPLAYLIST?

iKnow demo apps (part 4) - Rules Builder Demo

This is the fourth article in a series on iKnow demo applications, showcasing how the concepts and context provided through iKnow's unique bottom-up approach can be used to implement relevant use cases and help users be more productive in their daily tasks. Previous articles discussed the Knowledge Portal, the Set Analysis Demo and the Dictionary Builder Demo, each of which gradually implemented slightly more advanced interactions with what iKnow gleans from unstructured data.

This week, we'll look into one more demo application, the Rules Builder Demo, in which we'll build on previous work but again climb a step on the level ladder, implementing a more high-level use case than in the previous ones. The idea came from an opportunity where we were asked to help the customer in the finance sector make sense of vast volumes of contract data. They wanted to semi-automate the extraction of logical rules from that text (in fluent legalese!), so they could be fed into other systems. While this was an exciting use case to work on (and more on it in this GS2016 presentation), we've also used it in other cases, for example to extract mentions of ejection fraction from Electronic Health Records.

How to get custom HTTP request headers

I cant find any description on how to read custom http request headers in a REST service.

On some occations i want to read http headers passed along when customers uses our REST API or headers added by the CND provider. Does anyone know how to read these http headers?

For example:
cloudflair.com sends a vistors country information along to the server using a customer http header called "CF-IPCountry". We would like to read this information and use it for statistics.

iKnow demo apps (part 3) - Dictionary Builder Demo

This is the third article in a series on iKnow demo applications, showcasing how the concepts and context provided through iKnow's unique bottom-up approach can be used to implement relevant use cases and help users be more productive in their daily tasks. Previous articles discussed the Knowledge Portal, a straightforward tool to browse iKnow indexing results, and the Set Analysis Demo, in which you can use the output of iKnow indexing to organize your texts according to their content, such as in patient cohort selection.

This week, we'll look into another demo application, the Dictionary Builder demo, in which we'll marry iKnow's bottom-up insights with top-down expertise, organizing our domain knowledge into dictionaries that are composed of the actual terms used in the data itself. Sticking to a top-down approach only, you'd risk missing out on some terminology used in the field that a domain expert sitting in his office wouldn't be aware of.

NewBie's Corner Session 15 Executing Routines and Labels

NewBie's Corner Session 15 Executing Routines and Labels

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Routines and Labels

Routines are computer programs with a number of executable code lines.

Labels (also called tags) are points in a routine that can be called (executed). They subdivide routines into manageable modules (or subroutines).

Global references done internally by Cache

Using the method  ##class(%SYSTEM.Process).GlobalReferences() I'm able to know how many global references has been done in the process. But I'd like to know how many of those references has been done by my code and how many has been done by Cache itself.

When from a class I execute a method of another class, Cache is internally accessing globals (I suppose to get the code of the called method). I would like to not count those accesses done by Cache.

For example:

I've a method (Statistics) that counts the number of references done by another method (A).

Ensemble - Suppressing multiple Alerts (e.g. NAKs, validation, etc) using Ens.Alert process

We are using the Ens.Alert alerting process to send alerts (via email) to our external service desk application (Service Now). 

Is there a way to suppress multiple alerts for the same error (within a specified timeframe)? (Either Rule or BPL?)  (i.e.  a system starts sending bad data which fails validation or is NAKd by a downstream system -- causing every message to create an Alert.)

Otherwise, every message creates an Alert, which creates a ticket in Service Now.  

Thanks,

Brian

Production Monitor

At the Global Summit several folks had mention that they developed their own production monitor. I am looking to create a monitor similar to eGate that we only display those Services/Processes/Operations that are in trouble, and those Errors that are showing up in the Event Log. Does anyone have any examples of this?

Thanks

Where to find cache.node globals download?

Using Node.js with Caché - Introduction says the following:

The cache.node module is the Node.js interface for the GlobalsDB kit, which can be obtained from the GlobalsDB download page (http://globalsdb.org/downloads/). The Node.js interface can be used with either Caché or the free GlobalsDB database.
The installation kit includes detailed documentation on how to install and configure the cache.node module.

However, http://globalsdb.org/downloads gives a 404 and http://globalsdb.org just redirects to intersystems.com

Where can I find the files I need?

UDL highlighting in Atom text editor

Hello, guys. 

We have recently created a syntax highlighting for COS for Atom text editor. You can find it on https://github.com/intersystems-ru/atom-language-cos

Installation: 

  1. Download or clone this repository
  2. Copy everything to ~/.atom/packages/
  3. If you have your Atom editor open, then you need to reload it (enter  Window: Reload in Command line)

It's been few days since the release, so please if you find a bug, let us know through creating an issue or forking and making a pull request. 

P.S. After it gets more or less usable, we will use this syntax as a basis for GitHub highlighting for COS.

Creating a domain with the iKnow Domain Architect

In previous articles on iKnow, we described a number of demo applications (iKnow demo apps parts 1, 2, 3, 4 & 5) that are either part of the regular kit or can be easily installed from GitHub. All of those applications assumed you already had your iKnow domain ready, with your data of interest loaded and ready for exploration. In this article, we'll shed more light on how exactly you can get to that stage: how you define and then build a domain.
