We are very eager to learn what kind of feedback you might have for InterSystems.

We hope you had a chance to download and install one of the kits that show how the new process works. If not, you still can do it, following the instructions on these posts:

Our target release is InterSystems IRIS 2023.2 (and InterSystems IRIS for Health 2023.2) and will be available in a few months.

Hi Developers!

Often solutions with InterSystems IRIS BI can turn into a quite big solution with dozens of pivots and dashboards.

With every new IRIS BI solution release we can add changes that could influence the behavior of existing pivots or dashboards so they stop working. For example if we change the dimension or measure name, forget deploying some cubes or subject areas, conduct refactoring via mass renaming of cubes and its elements etc some widgets could stop functioning.

The solution is to test (manually?) every widget in every dashboard if the MDX queries are working.

I'm trying to extract data from an IRIS database into SQL server with SSIS using the ODBC driver: InterSystems ODBC35 (ODBC-2023.1.0.229.0-win_x64.exe)

I have Unicode turned off in the ODBC settings. 
I'm getting strange results - with some tables the SSIS ODBC connector will work but the ADO.net connector - using the same ODBC driver will. For other tables it's the other way round. The ADO.net sees the data as unicode and won't allow me to insert it into a non unicode table but ODBC will be fine.

In some cases I'm getting data that just looks screwed up  

Anyone had similar issues?

InterSystems announces its first preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Highlights

Many updates and enhancements have been added in 2023.2 and there are also brand-new capabilities, such as Time-Aware Modeling, enhancements of Foreign Tables, and the ability to use Ready-Only Federated Tables. Some of these features or improvements may not be available in this current developer preview.

Another important topic is the removal of the Private Web Server (PWS) from the installers.

In this brief article I would like to share a few strategies to run objectscript code in debug mode.

How to enter debug mode

There are two ways to launch the debugger.

Launching a command

Let's suppose that we have to debug the following method

Class Custom.Example Extends %RegisteredObject
{

/// check if a string can be a valid STP code ("STP" + 13 digits)
/// w ##class(Custom.Example).

In a tag-based CSP page, I can define (e.g.):

Is there any way to use this syntax to define an *instance* method (i.e., Method rather than ClassMethod) in the generated class?

I have a situation where I have a handful of classes which I need to copy to another Namespace (which uses a different RoutineDB) on the same instance, load it and compile it.

Can anyone help me come up with a command that will do this quickly and easily?   Perhaps something with extended reference?  

This is somewhat time sensitive so thank you in advance for your ideas!

Hi folks!

Just want to introduce you a new util to import CSV into IRIS - csvgenpy!

Install

USER>zpm "install csvgenpy"

Use:

do ##class(shvarov.csvgenpy.csv).Generate("file or url","table","schema")

Example:

USER>do ##class(shvarov.csvgenpy.csv).Generate("https://raw.githubusercontent.com/datasciencedojo/datasets/master/titanic.csv","titanic","data")

This will create table and class data.titanic in IRIS and will load the data.  you can proof it with:

USER>:sql

[SQL]USER>>select * from data.titanic

[SQL]USER>>select * from data.titanic

1. select * from data.

Has anyone had success with passing in a collections  property within a SOAP request to a Soap Service in Ensemble? Please reply with how you set up that collections property. I am able to successfully send a SOAP request correctly containing the elements of the collection property to Cache, as seen in a custom soap log file which I am using to troubleshoot. But the collection property in the  Ensemble request is not getting serialized, meaning MyContainers has nothing.

My.Request consists of a property, MyContainers, which can have 0 or more Containers (My.

In this article, we’ll build a highly available IRIS configuration using Kubernetes Deployments with distributed persistent storage instead of the “traditional” IRIS mirror pair. This deployment would be able to tolerate infrastructure-related failures, such as node, storage and Availability Zone failures. The described approach greatly reduces the complexity of the deployment at the expense of slightly extended RTO.

Hi Everyone,

 I tried to send the Sample XML from Packet Sender to Intersystems IRIS TCP Inbound adapter for learning purpose.
I'm using Predefine d Class : EnsLib.XML.TCPService and the adapter is EnsLib.TCP.CountedInboundAdapter (it selected by Default.)
My sample XML file would be <Patient><Name>John,Williams</Name><MRN>12345</MRN></Patient>
I got an error like 

ERROR <Ens>ErrTCPReadBlockSize: TCP Read(32000) with timeout period (50) failed with : (78):tElement><Patient><Name>Varatha</Name><MRN>12345</MRN></Patient></RootElement>
Please help me to proceed further

 These days the vast majority of applications are deployed on public cloud services. There are multiple advantages, including the reduction in human and material resources needed, the ability to grow quickly and cheaply, greater availability, reliability, elastic scalability, and options to improve the protection of digital assets. One of the most favored options is the Google Cloud. It lets us deploy our applications using virtual machines (Compute Engine), Docker containers (Cloud Run), or Kubernetes (Kubernetes Engine). The first one does not use Docker.

Hi all,

I'm wondering if exists any command or method to replace a text using parameters.

In C# I use the Format property

var text = string.format("My name is {0} and I'm {1} years","Kurro","18")
// The value of text will be "My name is Kurro and I'm 18 years"

I've tried with this code... but it works only for the specific parameters

set text = "My name is {0}, and I'm {1} years"
write $Replace($Replace(text,"{0}","Kurro"),"{1}",18)

is possible to do something for more args? I mean, use for a indeterminate number of args

Best regads

As you know ObjectScript has neither FOREACH system command nor system function.
But it has a wide room for creativity.

The task is to loop over a global or local array and do something FOR EACH element.

There are 2 possible solutions:

• creating a macro that generates the required code sequences
• creating an Extended Command to perform the action. Both ways are presented here. The macro is a generic and quite flexible solution and easy to adapt if required.

We are currently using different iterations of Ens.Director.EnableConfig items to start/stop objects within the Interoperability Namespace. We are looking for ways to minimize our downtime as we move from AIX to a new section of our Network and Red Hat Servers.

Besides using Ens.Director.EnableConfig item and waiting for a response, or just disabling the objects through the Namespace class file, is there a quicker way to stop Services and Operations to ensure the TCP disconnect is sent to those endpoints so we can move the networking rules to ensure they point to new servers?

InterSystems FAQ rubric

You can use the system routine ^DBSIZE to estimate the backup file size (see also Note 1).

^DBSIZE estimates the file size of full, cumulative, and differential backups of the databases selected in the database backup list.

The database backup list is created from [System Administration] > [Configuration] > [Database Backup] > [Database Backup List] in the Management Portal.

For more information, please refer to the document below.

An execution example is as follows.

Several steps should be done in order to secure the connection through xDBC clients to an IRIS Server instance using TLS. Most of the information can be obtained from the documentation about TLS on IRIS here, about configuring the security layer for encrypted connections. In the next paragraphs we will cover an step-by-step guide on how to configure and test the connection using SQL Clients apps using ODBC and JDBC.

In this article, we will establish an encrypted JDBC connection between Tableau Desktop and InterSystems IRIS database using a JDBC driver. While documentation on configuring TLS with Java clients covers all possible topics on establishing an encrypted JDBC connection, configuring it with Tableau might be a little bit tricky, so I decided to write it down.

Securing SuperServer

Before we start with client connections, you need to configure SuperServer, which by default runs on port 1972 and is responsible for xDBC traffic to accept encrypted connections.

I need to list the calls from all business service/processes (DTL, BPL and code)  - either to another business process or a business operation. i assume this is possible, as they can draw the lines on a production diagram so imagine there must be a way to do it but im scratching my head.    Any help appreciated...

I did some experiments on my local machine and found out that IRIS seems to associate each request (eg: CSP request) to a dedicated process named IrisDB.exe

This process has 3 threads, and one of them seems to be the main working thread (that will the handle request).

If I spawn many concurrent requests, the number of IrisDB processes on my local machine will grow (to make sure each request can be handled in parallel).

It seems there is a limit : it will create no more than 64 processes to handle requests (eg: even if 100 concurrent requests are send to IRIS).

Welcome, dear members of the community!

In this article we are going to demonstrate the great potential that IRIS/HealthConnect makes available to all its users with the use of Embedded Python and we are going to do it by developing a small production that will allow us to recognize and identify the faces present in a JPG file from some images that we will use as a reference.

Project configuration:

Let us begin! We have published the entire application in OpenExchange so that you only need to download and deploy it in Docker as you can read in the associated README file.

I deployed the IRIS container on my Mac M1 Docker Desktop Kubernetes cluster:

I limited the container 1.5Gb memory:

In the "merge.cpf" file I constrained IRIS memory usage aspects:

Now I load-test the container by multiple installing  and uninstalling the %ZPM package:

• install ZPM (zpm-installer.routine and execution):

Hi,

I use ZLANGC00 and ZLANGC01 for shortcuts at programmer level to some frequently used dev tools. Is there a way to pass 2 arguments to a command?

Example:

ZZQD "Queue1" // Equivalent to D ZZQD^%ZZLANGC00("Queue1") to display messages in queue1 (ZZQD is my own code in %ZZLANGC00)

but if I wanted to type ZZQD "Queue1" $H-3 to call ZZQD^%ZLANGC00("Queue1",$H-3) can it be done or do I need to write something to manipulate the argument? So ZZQD "Queue1-3"

I'm using the EnumerateJobStatus query of class Ens.Util.Statistics to obtain the LastActivity value of a Business Host.

I would expect that this would return the timestamp of the last message received by the BH, understanding that any connect/disconnect activity would reset that timer. However, the time returned appears to actually be the time at which Ens.MonitorService generated the alert and is not directly related to anything that happened in the BH itself.

Hello, I need to determine the best way to split a class containing multiple methods(about 20), into multiple classes in which each method is in its own class. I am wondering if there is another way other than manually creating the different classes, and copying each method into each class. Doing this in Intersystems Studio.
