NewBie's Corner Session 28 Various Methods to Traverse a Global

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

Judging from the number of responses to Session 27 Traversing A Global, developers are passionate about their methods. I am not here to judge the merit of the various methods.

Over the next few pages I will demonstrate a number of methods to Traverse a Global. If you don't already have a favorite they may help you pick one.

How to write the home address right?

How Tax Service, OpenStreetMap, and InterSystems IRIS
could help developers get clean addresses

Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.

Hi

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter.

Issue is ObjectScript.

So:

1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.

I this article we'll discuss:

  • GitLab installation and configuration
  • Connecting your environments to GitLab

Recently I needed a classmethod that returns annotation value based on a name of a activity.

As doing it at runtime seemed inefficient, I wrote compile-time utility that iterates over all business process activities and generates relevant code.

This code could be used in a variety of situations when you need to iterate over business process activities, just add it as a secondary superclass to your BPL processes.

Good Morning and thanks in advance for all replies. I have created a PowerShell script for backing up CACHE and all related files to be run on a nightly basis. My script works as long as the Unknownuser has %all access which is not acceptable in our production environment. I have tried every format I can thank of to get the script to use a specific id with no luck. How can I get this command to run under a specific id?

..\bin\cache -s. -U%SYS "##Class(Backup.General).ExternalFreeze() <d:\backup\login.scr"

The file just has

Consider the below scenario:

1. HL7 Service -> Process

2. DTL makes a call to a webservice (Post) via a REST operation via SendRequestSync call.

a. if the post is successful, end the DTL

b. if the server that hosts the webservice is down, i would like to keep retrying with the same message and not lose any messages in the queue.

does a simple "quit 0" at the DTL will rollback the message and will retry? please let me know how not to lose any messages if the webservice server is down.

Appreciate it.

LDAP Adapter - Credentials?

I'm writing an operation to use the LDAP Outbound Adapter to query AD.

The operation's settings include a basic Credentials selector, to allow you to use the built in Credentials function of Ensemble. This can be referenced in the operation with ..Adapter.Credentials

Currently to check if the class is mapped I call:

ClassMethod IsClassMapped(class) As %Boolean

{
  set sc = $system.OBJ.GetClassList(.classes,"/system=0 /percent=0 /mapped=0")
  quit $data(classes(class))
}

And it works, but I'm interested if there is a simpler approach out there?
