Introduction

HL7 V2 message routing solutions often have hundreds of business services, processes and operations. Inevitably things will go wrong and you have to monitor the production to be able to react quickly and resolve any problems before they can become serious issues.

Ensemble includes some powerful alerting capabilities that can help, but if you aren't careful you will be inundated with alerts and your inbox more or less becomes a copy of the event log defeating the object of the exercise.

2016.2 Field Test Kit 2016.2.0.585.0

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:

Presenter: Mark Massias
Task: Present complete, contextualized information to the people who must act as part of a (mostly) automated business process
Approach: Give examples of using InterSystems’ workflow engine.

More and more business processes are automated, but sometimes a person needs to make a decision. In some cases policies require an individual to approve an expenditure, or when loading data a person needs to sort out exceptions where the data in not clear. This session explains how to include people in business processes in a way that presents the user with a complete context for the decision they have to make.

Problem: Using human workflow to fix business process problems.

Content related to this session, including slides, video and additional learning content can be found here.

Countermeasures against SQL injection

InterSystems FAQ rubric

Countermeasures against SQL injection have been published on various websites, but we believe that it is possible to prevent SQL injection in applications using InterSystems SQL as well as other RDBMS by implementing these countermeasures appropriately. In addition, InterSystems Data Platform (hereinafter referred to as IRIS) incorporates several measures that make SQL injection more difficult than general RDBMS.

To remove InterSystems products installed on your Windows system, use Add or Remove Programs in Control Panel (in Windows 10, select Apps from Windows Settings).

Since we will be making changes to the system, you will need to log in as a user with administrator privileges.

1) Log in to the system as an administrator.

2) From the system tray, exit the launcher of the InterSystems product instance you want to uninstall (click launcher → exit).

Introduction

Application integration at its simplest is often just one application sending a message to another to notify it of some change. Perhaps when a patient arrives at a hospital, the registration system will send a message to clinical systems so they have all demographic data ready to use. Of perhaps it is just a nightly file transfer from the sales system to the accounting system.

But modern application integration platforms or suites can do a lot more than this to help applications work together and add real value to the enterprise.

Presenter: Louise Parberry
Task: Reduce the need for skilled developers to define and normalize data from outside sources
Approach: Use the Ensemble Record Mapper and other tools to automatically define comma-delineated and fixed-width data structures

If you need skilled software developers to define and normalize data coming from business partners or customers, you probably have a backlog of unsatisfied requests. The record mapper and other tools allow analysts to define comma delimited and fixed width data structures without needing a developer and this session explains how this can be incorporated into an application to create an efficient and effective way to clear that backlog.

This is a beginner’s guide to the design of a “MicroService” implemented in Ensemble. “MicroService” is a popular phrase these days which has a broad interpretation. My interpretation is: “MicroService” is a “NoSQL Service”. A what? The answer is in the article.

We learnt what the difference is between SQL and NoSQL databases. For me the difference is nearly the same between a SOA Web Service and a “MicroService”. I am going to explain it through an example.

Part 3. Appendix

InterSystems IRIS OAUTH classes explained

In the previous part of our series we have learned about configuring InterSystems IRIS to act as an OAUTH client as well as authorization and authentication server (by means of OpenID Connect). In this final part of our series we are going to describe classes implementing InterSystems IRIS OAuth 2.0 framework. We will also discuss use cases for selected methods of API classes.

The API classes implementing OAuth 2.0 can be separated into three different groups according to their purpose. All classes are implemented in %SYS namespace. Some of them are public (via % package), some not and should not be called by developers directly.

Currently, many of you has some knowledge about CachéQuality (which is being renamed to objectscriptQuality) for analyzing objectscript code using the rules we have predefined. Probably you have tested it and have found too many warnings in your projects. I'm sure there are issues which are really important for you and some others which you would like to dismiss.

Requirement: Transform source XML message to target JSON.

step1: First create json equivalent xml from any online tool.

step2: use add in studio utility create persistent classes from json equivalent xml and compile it , now target persistent classes are ready

step3: Do the above step for source xml or xsd and generate persistent classes for source and compile it

step4: complete the DTL by selecting root node from source, target persistent classes and complete the mappings and compile it

InterSystems FAQ rubric

For volatile tables (tables with many INSERTs and DELETEs), storage for bitmap indexes can become inefficient over time.

For example, suppose that there are thousands of data with the following definition, and the operation of bulk deletion with TRUNCATE TABLE after being retained for a certain period of time is repeatedly performed.

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"

Many mobile applications that enable users to get information about road fines and pay them, send notifications about newly added fines. This functionality can be efficiently implemented using push notifications sent to users’ devices.

Our application was not an exception. The server side is based on the Ensemble platform that offers integrated support of push notifications starting from version 2015.1.
