Beginner tag unites articles and questions for those who are getting started with InterSystems Data Platform

All time

Hi All, I am a Data Architect and am trying a method of deploying alter statements onto Cache DB.

My Data Modeling tool generates alters as this.. So question is if the Cache has a way to rename table? If so what is it?

ALTER TABLE <SchemaName>.GROUP_TYPE_NODES RENAME TO GROUP_TYPE_10082019140110000
;

This is giving error.

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

My first experience in using IAM

Experience & feedback from online course "Hands-On with InterSystems API Manager for Developers"

With my basic knowledge of Docker container and REST API, I would like to have my first try on using InterSystems API manager to take control of APIs and microservices. I have completed this online course using my local IRIS instance as host (Windows OS) and IAM running on a Linux VM (guest).

In this article, we will run an InterSystems IRIS cluster using docker and Merge CPF files - a new feature allowing you to configure servers with ease.

On UNIX® and Linux, you can modify the default iris.cpf using a declarative CPF merge file. A merge file is a partial CPF that sets the desired values for any number of parameters upon instance startup. The CPF merge operation works only once for each instance.

Our cluster architecture is very simple, it would consist of one Node1 (master node) and two Data Nodes (check all available roles). Unfortunately, docker-compose cannot deploy to several servers (although it can deploy to remote hosts), so this is useful for local development of sharding-aware data models, tests, and such. For a productive InterSystems IRIS Cluster deployment, you should use either ICM or IKO.

Introduction

Any election is a highly mysterious process, and when you look at its results, the overall picture is not quite clear. I decided to put them, region by region, on the map of Moscow using InterSystems technologies that offer both storage and data analysis functionality. In this particular case, I used InterSystems Ensemble, a platform for application development and integration, but you can also build this solution using the multi-model InterSystems Caché DBMS, as well as InterSystems’ new product called IRIS Data Platform.

Since now i have been working from external connection but i want to work with the SQL utility of Management Portal

i dont know how to do with several instructions like in other editors like this example

update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  80 where CodigoNum = '100' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '101' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '102' and Empresa = 'CO'

it returns

Hi, Community!

Someday you find yourself having a wonderful class package which can be helpful in several projects. So it is a library package.

How to make the classes available for different namespaces in Caché? There are two ways (at least two ways familiar to me):

1. Start the name of the package with %, like %FantasticLib.SuperClass. Wrong way.

If you do that the class would be placed in %SYS and would be available in other namespaces.

This is wrong because of the two reasons:

Is there any methods/ways through which will get to know whether any of the Unit Test cases is/are failing in the Terminal with status as either 0 or False in case of Failure & 1 or Ture in case of Test Passes (we are getting an url of the csp page with the report which has the passed failed status) as we need to send this failure status to Jenkins for the Build to Fail (where in we have acheived this part in making the build failure/success based on harcoded boolean)

Hi all. We are going to find duplicates in a dataset using Apache Spark Machine Learning algorithms.

Note: I have done the following on Ubuntu 18.04, Python 3.6.5, Zeppelin 0.8.0, Spark 2.1.1

In previous articles we have done the following:

I needed to know programmatically if last ran failed or not.

After some exploring, here's the code:

ClassMethod isLastTestOk() As %Boolean
{
  set in = ##class(%UnitTest.Result.TestInstance).%OpenId(^UnitTest.Result)
  for i=1:1:in.TestSuites.Count() {
    #dim suite As %UnitTest.Result.TestSuite
    set suite = in.TestSuites.GetAt(i)
    return:suite.Status=0 $$$NO
  }
  quit $$$YES
}

Good day, I would like to find out the size of Caché ObjectScript variable in order to guarantee that my program will not leak, equally in terminal and Caché globals. For example how huge number I can store in that variable ? And what happen in Caché when variable will leak ? How is this behavior treated? (how much memory is reserved for common variable?)

Thanks in advance for your answers.

Defragmentation

All replies are appreciated. We have put our first client into our production cache database and we are looking at what kind of regular maintenance is needed. We were questioning whether we should defrag the database files using windows defrag program and whether we need to run the defrag for Globals regularly? Should we be doing these routinely , occasionally or not at all?

InterSystems IRIS supports publish and subscribe message delivery. Publish and subscribe refers to the technique of routing a message to one or more subscribers based on the fact that those subscribers have previously registered to be notified about messages on a specific topic.

This article demonstrates how several InterSystems IRIS capabilities can work together:

In this article we would send emails about:

  • New workflow tasks
  • Unassigned workflow tasks
  • Uncompleted workflow tasks
  • Ensemble alerts

Email recipients would be determined using Publish/Subscribe operation and each user would receive only digest email whenever possible.

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

NewBie's Corner Session 17 New command

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

New command

The New command limits a variable's scope or range of use. In theory the New command is simple, in reality the New command is powerful and needs to be respected and understood. In Caché ObjectScript and MUMPS an entire chapter is devoted to it.

There are three variations of the New command:
