#InterSystems IRIS

This week I am going to look at CPU, one of the primary hardware food groups :) A customer asked me to advise on the following scenario; Their production servers are approaching end of life and its time for a hardware refresh. They are also thinking of consolidating servers by virtualising and want to right-size capacity either bare-metal or virtualized. Today we will look at CPU, in later posts I will explain the approach for right-sizing other key food groups - memory and IO.

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

         /gbl - for globals

And the ObjectScript should be in CLS (a.k.a UDL) and not in XML.

Example.

Ok!

Hi everyone,

I am pleased to announce that the Evaluation Service is now LIVE!

If you are an InterSystems End User or an InterSystems Partner and you want to try the latest version of IRIS with all its enterprise features (mirroring, ECP and sharding), and you want it NOW, this is for you.

The Evaluation Service allows you to get your hands on an IRIS kit and a very powerful IRIS license for evaluation purposes in less than 1 minute. No paperwork. No need to talk to anyone. Fully self-service.

This service is only for IRIS and IRIS for Health and it is very easy to use.

We are pleased to invite you to the upcoming webinar "Master Data Management and Your Enterprise" on 3rd of September at 11:00 EDT!

Hi folks,

I started to play with docker and InterSystems products, it's amazing, but I got the error when try to load the IAM-0.34-1-1.tar.gz image to docker:

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker load -i IAM-0.34-1-1.tar.gz
open /var/lib/docker/tmp/docker-import-547148651/IAM/json: no such file or directory

Bellow docker and docker-compose version:

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker --version
Docker version 19.03.2, build 6a30dfc

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker-compose --version
docker-compose version 1.18.

I am happy to announce that InterSystems API Manager is now generally available. InterSystems API Manager (IAM) is a new feature of the InterSystems IRIS Data Platform™, enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure.

InterSystems has corrected a defect in applications that use Unicode character 223 (ß). This defect can result in incomplete query results, class compilation errors, and removal of custom SQL privileges.

This problem occurs on systems that are running or have previously run on:

• Caché and Ensemble 2018.1.0, 2018.1.1, and 2018.1.2
• HealthShare Health Connect (HSAP) 15.032 on Core versions 2018.1.0, 2018.1.1, and 2018.1.2
• HealthShare Health Connect 2019.1
• InterSystems IRIS data platform – all currently released versions
• InterSystems IRIS for Health – all currently released versions

The defect is triggered by data and component names containing Unicode character 223 (ß). In the versions listed above, an uppercase conversion incorrectly maps that character to Unicode character 7838 (ẞ).  Applications perform this uppercase conversion using features such as $ZCONVERT and %SQLUPPER.

Problems can occur when accessing data or classes created or modified on a product with a different uppercase conversion than the one currently in use.

Multi-Model Development

Hi guys!

Was coding today with InterSystems IRIS in a docker container and decided to share with you the commands you may find useful in everyday coding.

# docker-compose build

command to build a container. Remember, it is useful if you have dockerfile in the repo.

if the build is successful call the following to launch it:

# docker-compose up -d

Find IRIS management portal on:

localhost:port/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS

where the port is what you set in docker-compose.yml - 52775 in this case.

Run the following if you want to launch a terminal session inside IRIS container:

# docker-compose iris iris session iris

gfhj gj 


sdfdsfsdf





USER>

And run the following to shut down the container:

# docker-compose down

Troubleshooting

Hi Team,

When I use below statement , I got SQLCODE=0.

SET rs = ##class(%SQL.Statement).%ExecDirect(, "SELECT * FROM LISDB.ExternalUsers WHERE UserId = 83")

If I display above query using   Write (rs.%Display())  it gives me below result but   (rs.%Get("Prefix")) method give me null value.

Please help

Hi Everyone,

Are you ready yet? Have you packed all you'll need for the summit? And don't forget the needed power-socket adapters if you come from outside the US! 

Have you signed up for the Container Bootcamp on Sunday? Or one of the various Experience Labs, the many informative sessions and one of the symposia on Wednesday afternoon?

Again, there is a mobile app for attendees that should help you keep it all under control and even allow you to book time with InterSystems personnel for a one-on-one deep-dive on whatever you need.

My fantasy didn't go beyond periodically running %SYS.Journal.System:Progress() class query, while I'd prefer to use an event handler of some kind. Any ideas?

Hi Developers!

InterSystems Package Manager (ZPM) is a great thing, but it is even better if you don't need to install it but can use immediately.

There are several ways how to do this and here is one approach of having IRIS container with ZPM built with dockerfile.

I've prepared a repository which has a few lines in dockerfile which perform the download and install the latest version of ZPM. 

Add these lines to your standard dockerfile for IRIS community edition and you will have ZPM installed and ready to use.

To download the latest ZPM client:

I'm happy to announce the latest Python Gateway release.

This is not an InterSystems product, it is community supported open source project.

Download new release from GitHub.

Now for the new features.

Fast transfer. Pass globals, classes and tables from InterSystems IRIS to Python with ease and speed (10x faster than old QueryExecute). Documentation.

Proxy Gateway allows generation of ObjectScript classes for Python classes. Instantinate objects, call object and class methods using familiar ObjectScript code (docs).

set module = "random"
set sc = ##class(isc.py.gw.Generator).

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

Hi Everyone!

New video, recorded by @Stefan Wittmann, is already on InterSystems Developers YouTube:

JSON and XML persistent data serialization in InterSystems IRIS

Hi All,

I would like to install Intersystems IRIS studio, So I went this link 

https://login.intersystems.com/login/SSO.UI.Login.cls?referrer=https%25…

But I am getting the below error.

So what will be the next step for me!!! please guide me........

Hi all,

I recently discovered the Monitoring Activity Volume feature in IRIS and I was amazed by it. So, I put it to work in one of our productions. It is nice how easy it is to set up and all the possibilites that came with it.

But there's something weird: the numbers. Actually, one of the BP is stating a time of more than 6 seconds to process:

But it is not really possible, as our production is running at a pace of about 40 msg/second, being this one the first step. So my question is: how is this avg. duration calculated? What does this time include? Is it in seconds?

Thanks a lot,

Hi,

I am implementing free search text box, which can search data in all columns of tables.

I have created DisplayName column by concatinating two column data with space.

SELECT TOP ALL FirstName||' '||LastName AS DisplayName, UserType, IsActive, RoleName, DOB FROM LISDB.ExternalUsers

Now, in where condition I want to do like search in DisplayName column but it not working.

I have tried both fn CONCAT and  || in like query but both are not working for me.

Hello Everyone,

I want to Know Caché or IRIS has some way to communicate with DDE or RTD from Excel?

Introduction

Since version 2019.2, InterSystems IRIS has provided their Native API for Python as a high-performance data access method. The Native API allows you to directly interact with the native IRIS data structure.

Preview kits are now published via the WRC's preview download site for:

• InterSystems IRIS 2019.1.1
• InterSystems IRIS for Health 2019.1.1
• HealthShare Health Connect 2019.1.1

The build number for these releases is 2019.1.1.608.0.

This is a maintenance release and includes changes in a number of areas, as described in the online documentation here.

It also includes three new features, described in the online documentation here:

• Support for the InterSystems API Manager,
• In-place conversion from Caché and Ensemble to InterSystems IRIS
• X12 element validation.

Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that implements a certain algorithm.

Here's a list of Code Golf competitions we had on Developers Community.

• Output 9876543210 without using numbers
• How can I make my text behave in accordance with gravity?
• Drawing Boxes
• FizzBuzz

And some interesting challenges:

• Can you crack the Black Box?
• Convert Cyrillic to Latin

Did I miss something? Add more challenges in comments.

Just wanted to share my Zabbix template for monitoring InterSystems IRIS on Linux servers.

It monitors irisusr (configurable) memory consumption:

• Virtual memory size
• Percentage of real memory
• Resident set size
• Size of data segment
• Size of code segment
• Peak resident set size
• Size of locked memory
• Size of shared libraries
• Peak virtual memory size
• Size of pinned pages
• Size of page table entries
• Size of process code + data + stack segments
• Size of stack segment
• Size of swap space used

How to use:

1. Check that you have Zabbix installed (I'm using version 4.

Is there a way to set null in dynamic object without using %Set methods?

I have this method and I need to set NULL as, well, null and not string.

ClassMethod node(name) [ CodeMode = expression ]
{
{
    "name":(name),
    "content":($case(##class(%Dictionary.ClassDefinition).%ExistsId(name), $$$YES:"mycontent", $$$NO:"NULL"))
}
}

Hi,

I want to do ordering dynamically in Query. I mean to say that order by value will not be hard coded in query, it will be passed in parameter.

I have tried to it following way, but it is not working for me. Can you please advise me how can I achieve it?

In below code, Order by :objSearch.SortingField is not working.

Class Query.ExternalUsers Extends %Library.RegisteredObject [ ClassType = "", DdlAllowed, Owner = {_SYSTEM}, Not ProcedureBlock ]

{



Query Search(objSearch As LISSystem.ModelView.
