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:

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

So that's it!

Basically it does the same thing as csvgen does, but uses python library sqlalchemy which works because of embedded python and sqlalchemy-iris by @Dmitry Maslennikov

P.S. csvgenpy can import some "complicated" for csvgen csv as this one

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"

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

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

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?

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.

Estimate backup size with ^DBSIZE [IRIS]

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.

LS,

I'm trying to learn how to use the IKO for deploying solutions to Kubernetes. In my current project I'm trying to deploy the IAM onto a K8S context. Are there directly usable samples of the yaml file I need to use for that?  

InterSystems FAQ rubric

In Windows, set the processes with the following image names as monitoring targets.

[irisdb.exe]

contains important system processes.
* Please refer to the attachment for how to check important system processes that should be monitored.

[IRISservice.exe]

This is the process for handling IRIS instances via services.
When this process ends, it does not directly affect the IRIS instance itself, but stopping IRIS (stopping the service) is no longer possible.

[ctelnetd.exe]

%Service_Telnet Starts when the service is enabled and becomes a daemon process to access IRIS via Telnet.

Has anyone seen this before? I'm new/bad at Docker and not even sure how to debug.

The Amazon Web Services (AWS) Cloud provides a broad set of infrastructure services, such as compute resources, storage options, and networking that are delivered as a utility: on-demand, available in seconds, with pay-as-you-go pricing. New services can be provisioned quickly, without upfront capital expense. This allows enterprises, start-ups, small and medium-sized businesses, and customers in the public sector to access the building blocks they need to respond quickly to changing business requirements.

I'm trying to update the hosts file on Windows in C:\Windows\System32\drivers\etc

I know that in Linux if you update the hosts file, you sometimes need to restart the Network Manager for the changes to take effect.

So my question is that is there a similar thing that we need to do on Windows or do the changes take effect as soon as the file is saved?

This is a  rather personal view of the history before Caché.
It is in no sense meant to compete with the excellent books from Mike Kadow discussed in an earlier article.
We have different histories and so this is meant to create a different perspective of the past.

The whole story started in 1966 at MGH (Mass.General Hospital) on a PDP-7 Ser.#103
with 8K of memory (18-bit words) [ today = 18K byte ]  as a spare system.

"Serial Number 103 - was located in the basement of the now demolished Thayer Building,
currently [2014] the site of the Cox Cancer Center at MGH.
