Hello everyone

I have a problem with $ ZF (-1)

I need to delete file from windows folder example c: \ sys \ text.txt, when executing the w $ zf (-1, "c: \ sys \ text.txt") command, the file does not delete.

Does anyone in the developer community have experience implementing a customized SDA3 container within HealthShare? There is a course on the learning site (ISC1086) that discusses how to do this, but it's currently listed as "coming soon" and I'm hoping to find some documentation.

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

  • Generation of an AST for a GraphQL request and its validation
  • Generation of documentation
  • Generation of a response in the JSON format

%Status usage in ObjectScript

Hi developers!

Want to discuss with you the case of %Status.

If you familiar with ObjectScript you know what is it. I'd love to hear the history of the case why it had appeared in ObjectScript but it turned out that almost every system/library classmethods return %Status and there is a whole set of tools to deal with it.

What is does it gives you the responsibility to check the value or %Status of every system method you call.

E.g. if you save the data of the persistent class, you should never call like this:

do obj.%Save()

you need to call:

set sc=obj.%Save()

if $$$ISERR(sc) do // something or quit.

I like to know if COS has a PGP library for encryption and decryption messages received from an SFTP connection. We have interfaces that we used BouncyCastle in C# but would like a native library for COS.

Hello All,

I hope it's not a silly question.

Here is my issue:
I have 3 simple classes:

Parent class, let's say:

Class ParentClass Extends %RegisteredObject
{
Property a As %String;
}

and two children classes
Class A.Child Extends ParentClass
{
Property b As %String;
}

Class B.Child Extends ParentClass
{
Property c As %String;
}

So no issues - all compiles and seem to work.

But, when I add %XML.Adaptor to my parent class, so:

Internally we use splunk for monitoring applications and network.

Does Ensemble have a way of exposing internal metrics and/or a way of exposing custom built metrics?

I've used Deepsee dashboards in the past to monitor Apache Tomcat/Apache Camel/hawtio using JMX rest calls. This is the other way around and ideally I'd like to expose metrics on:

Cache docker image

Hello all,

I am having some issues creating a docker image with a fresh cache installation. The error that I am getting right now is that gzip is required for a cache installation, but was not found in my system. Even though, this is shown as installed in the base centos 7 image. My host machine is Windows 10 using the latest docker version.

Here is my dockerfile, its simple:

Hi folks!

Sometimes we need to import data into InterSystems IRIS from CSV. It can be done e.g. via csvgen tool that generates a class and imports all the data into it.

But what if you already have your own class and want to import data from CSV into your existing table?

There are numerous ways to do that but you can use csvgen (or csvgen-ui) again! I prepared and and example and happy to share. Here we go!

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 :

Send an HTML Email

This code snippet contains the class method "test" which sends an HTML email. Change the literal strings in the method to customize the email's from address, to address, subject, and body:


Class objectscript.sendEmail Extends %RegisteredObject

    classmethod test() {
        set m=##class(%Net.MailMessage).%New()
        set m.From="user@company.com"
         
        set m.IsHTML=1
         
        do m.To.Insert("user@company.com")
        set m.Subject="Sent by IRIS mail"

I have posted to aid others in diagnosing problem with SSL/TLS connections to superserver port from .NET client executable.

The cache instance this appeared on is quite old - 2011 - so I do not know if Intersystems have added a better error message in a later version

The actual fault was due to the certificate in the %SuperServer SSL/TLS configuration having expired.

The unhelpful message that appeared in the .NET client included the following partial stack trace.

Hi Developers!

As you know the concept of ObjectScript Package Manager consists of ZPM client - client application for IRIS which helps you to install packages from the registry. And the code which works "on the other side" is ZPM Registry - server which hosts packages and exposes API to submit, list and install it. Now when you install the ZPM client it installs packages from community package registry, which si hosted on pm.community.intersystems.com

But what if you want your own registry? E.g. you produce different software packages for your clients and you want to distribute it via private registry? Also, you may want to use your own registry to deploy solutions with different combinations of packages.

Is it possible? The answer is YES! You can have it if you deploy ZPM registry on your server with InterSystems IRIS.

To make it happen you would need to set up your own registry server.

How to do that?

So I have an interesting problem. I am going to be using a process and rule to determine if an HL7 message qualifies to be sent out, then using a record map to write certain aspects of that HL7 message to disk (with an HL7 to record map DTL). This is simple enough but the recipient of this file is requiring a single record map entry per DG1 segment in the HL7 message.

For instance if said HL7 message for PATIENT^TEST has 3 DG1 segments, I would need to write three lines (or records) like so:

123^^^^MR|TEST|PATIENT|DG1(1) TEXT|DG1(1) CODE|DG1(1) DATE

We are in the process of setting enabling SSL on a soap web service exposed via InterSystems, but are running into trouble. We have installed our certificates on our webserver (Apache 2.4) and enabled SSL over the default port 57772. However, we now get an error when sending a soap message to the web service (it used to work over http). Specifically the CSP gateway refuses to route te emssage the soap web service:

In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.

In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.
