Build iris image with cpf merge

When it comes to build an iris image, we can use the cpf merge files.

Here is an cpf merge example:

CreateDatabase:Name=IRISAPP_DATA,Directory=/usr/irissys/mgr/IRISAPP_DATA

CreateDatabase:Name=IRISAPP_CODE,Directory=/usr/irissys/mgr/IRISAPP_CODE

Wanted to share something I learned recently while working on a problem. We needed to add and change some Business Hosts in one of our edge productions.

In the past, we simply added the production class to CCR and then spreading it around. But there was a problem because different developers were working on different things, and we only wanted to include only the relevent production changes onto the CCR.

Here's a little piece of code that can help add new things to an existing production:

When analyzing data, there is often a need to look at specific indicators more thoroughly and to highlight sections of information of particular interest to a user.

For instance, examining the data dynamics for specific regions or dates can help us uncover some hidden trends and patterns that will allow us to make an informed decision about our project in the future.

The part II you will learn how to run any Jasper report file (jrxml file) designed on Jasper Studio from InterSystems IRIS. We will create a REST API to return a processed report on PDF format.

The jrxml file

On part I, we designed this report:

1. First of all, rename the report from Blank_A4.jrxml to sample.jrxml (Project Explorer tab > click right the file > Rename):

Last Friday November 17 suddenly ran into an error where ZPM would issue an error saying:

ERROR! Object open failed because 'Name' key value of 'xx' was not found

I googled but found no specific help. Step by step I was able to conclude that:

  1. This is the error message for error 5770, also known as $$$KeyValueNotFoundOpen.

  2. In objectscript, this error can be raised by calls to NameOpen, where 'Name' is the first quoted part in the error message.

The InterSystems IRIS has a series of facilitators to capture, persist, interoperate, and generate analytical information from data in XML format. This article will demonstrate how to do the following:

  1. Capture XML (via a file in our example);
  2. Process the data captured in interoperability;
  3. Persist XML in persistent entities/tables;
  4. Create analytical views for the captured XML data.

Capture XML data

The InterSystems IRIS has many built-in adapters to capture data, including the next ones:

DTL TechFAQ

Ensemble is based on message flow, and a data transformation is a way to convert from one message type to another. DTL (Data Transformation Language) adds a layer to this - it provides a graphical way to do the conversion. This is really helpful because most of the time, people with domain-specific knowledge may not have extensive coding skills. However, you always have the ability to do some coding, so if you need or want to, this is available.

DTL has several components: the data transformation engine, the language itself, and the DTL editor.

Why You Should Consider the Cloud

Introduction

By now, anybody working in the technology sector will have heard of Cloud computing. But the concept is increasingly being paid attention to outside of IT departments, with growing recognition among boardlevel executives of the potential of this range of innovations. Frequently, senior personnel are hearing stories about how the Cloud helps organizations reduce costs, boost efficiency and expand their operations, so they’ll be excited about what the Cloud can do for them.

Executive Summary

InterSystems HealthShareÆ and InterSystems EnsembleÆ both provide a rapid integration and development platform with built-in capabilities for the high-speed processing of HL7 messages. For the purposes of HL7 v2 message routing the two products are equivalent in performance. For brevity, this document will just say Ensemble in many places but it should be taken to apply equally to both products.

Caché for MultiValue Developers

InterSystems has implemented a broad set of MultiValue extensions for its Caché multidimensional database. These extensions enable the migration of MultiValue applications to Caché and bring the full range of Caché object and SQL development technologies to MultiValue developers. The result: your existing MultiValue investments are preserved, you gain a broad spectrum of highly scalable deployment options, and your developers can combine the best of MultiValue, object, relational, and technologies to extend existing applications and build new ones.

Presenter: Stefan Wittmann
Task: Take advantage of the NoSQL paradigm without adding another tool
Approach: Provide sample use cases that are an excellent fit for InterSystems’ new document data model

Description: Designing applications always requires you to make assumptions about your data model. Come to this session to learn how you can effectively handle the cases where you have to rapidly evolve your model. We will also discuss other use cases that are an awesome fit for the flexible document data model.

Problem: I’ve observed the NoSQL landscape and like the direction, but I have no use-case that fits and I do not want to add yet another tool.

Solution: InterSystems now has support for a well integrated document data model that brings the NoSQL paradigm to the enterprise within your current stack.

Task: Build a composite application that bridges data silos
Approach: Give a real-world example of combining data from multiple sources to run a composite application

Most organizations need to bridge silos of data or combine separate applications. This session describes techniques for building composite applications and silos. The session also looks at a real application that does this. It uses workflow to assign cases to individuals for investigation and extracts information from multiple systems to provide the investigator with a complete context for the case at the scene of the incident.

Today I'm releasing a new EWD 3 module - ewd-feder8.

ewd-feder8 is a federation or integration platform, built as an extension of the EWD 3 ewd-xpress module. So what does it do and what's it for?

It's all about federating and integrating multiple web or REST service end-points.

At its simplest you can use it as a proxy server in front of a remote web service or REST end-point.

NewBie's Corner Session 21 Parameters Part II

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

Parameters

In the previous session we saw how to call RtnB from RtnA with Parameters.

We also defined Parameters as another name for Variables when used in passing data from one Routine to another, or, from one Label to another.

Calling a routine from a Label, or to a Label, from within a routine is very similar to calling a routine itself.

I tried to make atelier look more like XCODE with this simple trick or tip: change the default font to SF Mono and size 14.

To do it I did:

1) Install SF Mono font in the system which is the default font for XCODE and needs to be installed in order to use it.

You can find it in: /Applications/Utilities/Terminal.app/Contents/Resources/Fonts

Double Click SFMono-Regular.otf file and install it. You will get a warning of "serious problems" but it will work all right.

In our last lesson, we added some formatting and validation to our Edit Widget form. So, now we are ready to add the ability to add new Widgets to our application. However, the great Widget Wars have come to an abrupt end, as Widget Direct has purchased its biggest competitor, WorldWideWidgets. In order to maintain some continuity, we need to display their catalog on our new application.

Indexing of non-atomic attributes

Quotes (1NF/2NF/3NF)ru:

Every row-and-column intersection contains exactly one value from the applicable domain (and nothing else).
The same value can be atomic or non-atomic depending on the purpose of this value. For example, “4286” can be
  • atomic, if its denotes “a credit card’s PIN code” (if it’s broken down or reshuffled, it is of no use any longer)
  • non-atomic, if it’s just a “sequence of numbers” (the value still makes sense if broken down into several parts or reshuffled)

This article explores the standard methods of increasing the performance of SQL queries involving the following types of fields: string, date, simple list (in the $LB format), "list of <...>" and "array of <...>".

Simple Remote Server Control

This example is extracted from a long-running installation.
The purpose is to have simple monitoring of several servers at a rather primitive level.
Just slightly more intelligent than a raw PING. But still easy to integrate.
It avoids the overkill of information you are often confronted with while you are just
interested in the number of active processes or similar basic figures.
The example shows a basic skeleton that might be easily filled by your real needs.

It consists of 3 sections:

Hi Developers!

When you prepare your modules for ZPM (InterSystems Package Manager) it expects the certain directory structure for ObjectScript source files.

ObjectScript in your source folder need to be stored by types in the following subfolders. E.g. if you have the source folder named as /src the structure should be as follows:

/src

/cls - for classes

/inc - for include files

/mac - for mac files

/int - for interpretable files

Snapshot to JSON

This is a sample to use %JSON.Adaptor class available in IRIS to produce a snapshot of your object.

The sample consists of 2 classes that are variations of what was known in Caché/SAMPLES as Sample.Person.
Be aware that the possibilities are limited by %JSON.Adapter and how you make use of it.

Once in place, you create some test data by Populate().
You select an object and take a snapshot.
You apply changes to your object and take another snapshot.
And see the difference.

BINGO!
