InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Hi guys!

As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).

1. Get it by as a property of an instance with "Object access":

ClassMethod GetPropertyForID(stId As %Integer) As %String

{

set obj=..%OpenId(stId)

return obj.StringData

}

2. Get it as a value of a column of the record with "SQL access":

We're excited to continue to roll out new features to InterSystems IRIS Cloud SQL, such as the new Vector Search capability that was first released with InterSystems IRIS 2024.1. Cloud SQL is a cloud service that offers exactly that: SQL access in the cloud. That means you'll be using industry-standard driver technologies such as JDBC, ODBC, and DB-API to connect to this service and access your data. The documentation describes in proper detail how to configure the important driver-level settings, but doesn't cover specific third-party tools as - as you can imagine - there's an infinite number of them.

In this article, we'll complement that reference documentation with more detailed steps for a popular third-party data visualization tool that several of our customers use to access IRIS-based data: Microsoft Power BI.

Configuring IRIS autostart on Linux

For practical reasons, it may be desirable that after a Linux server restart, the IRIS instance is automatically started.

Below you will find the steps to follow to automate the startup of IRIS during a reboot of the Linux server, via systemd :

1. Create an iris.service file in /etc/systemd/system/iris.service containing the following information

Random Read IO Storage Performance Tool

New Tool Available

Please see PerfTools IO Test Suite for a later version of the Random Read IO tool.

Purpose

This tool is used to generate random read Input/Output (IO) from within the database. The goal of this tool is to drive as many jobs as possible to achieve target IOPS and ensure acceptable disk response times are sustained. Results gathered from the IO tests will vary from configuration to configuration based on the IO sub-system. Before running these tests ensure corresponding operating system and storage level monitoring are configured to capture IO performance metrics for later analysis.

Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.

We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:

Working on a project where we have a web browser that we have to determine a pickup date/time for a pharmacy in a different time zones.

We store the different time zones with their Daylight and Standard offsets.

We have a object script method that figures out the the pickup date/time for a particular pharmacy in their local time zone but the data is being returned in the $H format.

The task is to find all globals that are referenced in certain routines. I could search for ^ using class(%Studio.Project).FindInFiles but that would also find ^ in comments and function calls. I can distinguish between a global and a function call visually, but it would be lovely to be able to skip function calls programmatically. Is it possible?

I am aware that we have 5 License Units on Community Edition. But I have issues figuring out how it's working.

I have Community Edition

USER>write $system.License.KeyCustomerName()
InterSystems IRIS Community

Freshly started system, only terminal session open, so, only one license units used, and 4 left. As expected

USER>write $system.License.LUConsumed()
1
USER>write $system.License.LUAvailable()
4

Quote from documentation - $SYSTEM.License.MaxConnections() returns the maximum number of connections a user can make while consuming one license unit. 

USER>write $system.License.MaxConnections()

Hi Developers!

Recently we launched InterSystems Package Manager - ZPM. And one of the intentions of the ZPM is to let you package your solution and submit into the ZPM registry to make its deployment as simple as "install your-package" command.

To do that you need to introduce module.xml file into your repository which describes what is your InterSystems IRIS package consists of.

This article describes different parts of module.xml and will help you to craft your own.

I will start from samples-objectscript package, which installs into IRIS the Sample ObjectScript application and could be installed with:

zpm: USER>install samples-objectscript

It is probably the simplest package ever and here is the module.xml which describes the package:

<?xml version="1.0" encoding="UTF-8"?>
<Export generator="Cache" version="25">
  <Document name="samples-objectscript.ZPM">
    <Module>
      <Name>samples-objectscript</Name>
      <Version>1.0.0</Version>
      <Packaging>module</Packaging>
      <SourcesRoot>src</SourcesRoot>
      <Resource Name="ObjectScript.PKG"/>
    </Module>
  </Document>
</Export>

Hi!

I believe the simplest is (to work with csv delimited by ";"):


set file = ##class(%File).%New( "data.csv" )
    set sc = file.Open( "R" ) 
    if $$$ISERR(sc) quit    ; or do smth

    while 'file.AtEnd {
        set str=file.ReadLine() 
        for i=1:1:$length( str, ";" ) {
            set id=$piece( str, ";" ,i ) 
            write !, id  // or do smth
        }
    }
    do file.Close()

Possible options:

different variants of error handling with sc code.

Embrace while loop into try/catch block.

And what's yours?
