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.

So the questions are:

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

Hi Developers!

Just want to share the information with you that we support TechCrunch Disrupt Hackathon 2019 this year!

It will take place from 2-4 of October in San Francisco, CA.

We introduced InterSystems special prizes for participants which solutions will use InterSystems IRIS $4,000 and InterSystems IRIS for Health 4,000.

Learn more here.

If you happen to participate we wish you luck and hope you'll leverage InterSystems IRIS data platform functionality to win Disrupt Hackathon 2019!

Error to load IAM image

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

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.

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

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.

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:

Python Gateway 0.8 release

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.

Replacing character groups

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 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:

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.

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"))
}
}
