Released with no formal announcement in IRIS preview release 2019.4 is the /api/monitor service exposing IRIS metrics in Prometheus format. Big news for anyone wanting to use IRIS metrics as part of their monitoring and alerting solution. The API is a component of the new IRIS System Alerting and Monitoring (SAM) solution that will be released in an upcoming version of IRIS.
A few months ago I touched on a brief note on "Python JDBC connection into IRIS", and since then I referred to it more frequently than my own scratchpad hidden deep in my PC. Hence, here comes up another 5-minute note on how to make "Python ODBC connection into IRIS".
It is with great pleasure that the CIUSSS de l'Estrie - CHUS is sharing the mocking framework it developed and presented at the InterSystems Summit 2017. I will update this post with more detailed instructions in the next few weeks but I wanted to share the code and presentation quickly :
Sometimes, it comes in very handy (especially for the EAV model) to use array properties in a class and be able to qickly search by their elements: both the key and the value.
Below is a simple alert processor based on the EnsLib.HTTP.OutboundAdapter to send text alerts via an SMS Gateway service. Typically, all that is needed to send an HTTP Post to the gateway service is the destination phone number, a source phone number, credentials, and the URL.
The code below is based on the Anveo gateway whose interface is as follows:

AWS Glue is a fully managed ETL (extract, transform, and load) service that makes it simple and cost-effective to categorize your data, clean it, enrich it, and move it reliably between various data stores.
In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:
Git 101
Git flow (development process)
GitLab installation
GitLab Workflow
Continuous Delivery
GitLab installation and configuration
GitLab CI/CD
In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.
In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.
Since InterSystems has recently announced the discontinuation of support for InterSystems Studio starting from version 2023.2 in favor of exclusive development of extensions for the Visual Studio Code (VSC) IDE, believing that the latter offers a superior experience compared to Studio, many of us developers have switched or are beginning to use VSC. Many may have wondered how to open the Terminal to perform operations, as VSC does not have an Output panel like Studio did, nor an integrated feature to open the IRIS terminal, except by downloading the plugins developed by InterSystems.
Here you will find info about badges of the Developer Community & InterSystems Global Masters Advocacy Hub, and the complete list of badges with descriptions on how to get them.
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.
Recently I have been posting some updates to our JSON capabilities and I am very glad that so many of you provided feedback. Today I would like to focus on another facet: Producing JSON with a SQL query.
I have recently come across a problem saving TrakCare reports as PDF files while using the MS Edge browser on a Windows 10 PC. Whenever a user selected the Save to PDF option the window Tab would crash and reset. The event was trapped and viewable in the Windows Events Viewer and showed a Fault in the AcroPDFImpl64.dll.
Embedded SQL is a tool that allows us to execute SQL statements in Caché Object Script. For example, to select the name of a person with a particular SSN from the Sample.Person class we can do the following:
The technology of load balancing between several servers with relatively low capacity has been a standard feature of Caché for quite a while. It is based on the distributed cache technology called ECP (Enterprise Cache Protocol). ECP provides a host of possibilities for horizontal scaling of an application, and yet keeping the project budget fairly low. Another apparent advantage of ECP network is the possibility to conceal its architecture in the depths of Caché configuration so that applications developed for the traditional (vertical) architecture can be fairly easily migrated to a horizontal ECP environment. The ease of this process is so mesmerizing, that you start wishing it was always this way. For instance, everybody is used to having a possibility to control Caché processes: the $Job system variable and associated classes/functions work magic in skilful hands. Stop, but now processes can end up being on different Caché servers…
This article is about how to gain as much transparency in controlling processes in ECP environment as in traditional (non ECP) one.
(Originally posted on Intersystems CODE by @Eduard Lebedyuk, 10/12/15) The following code snippet outputs all filenames in the file path "dir" in the Cache/IRIS terminal. The class method "test" runs the code:
Class eduardlebedyuk.filenamesInDir Extends %RegisteredObject
{
classmethod test() {
// replace dir with file path you want
set dir = "D:\directory"
set dir = ##class(%File).NormalizeDirectory(dir)
set file=$ZSEARCH(dir_"*")
while file'="" {
write !,file
set file=$ZSEARCH("")
}
}
}
I am an avid user of ZEN for over 10 years now and it works for me. But it seems that Intersystems are no longer actively developing it (or ZEN Mojo), the only published reference to this is here
When a company is quite large and many different applications used by employees. But while those applications are mostly completely different, how to make it possible to not force users to enter credentials as many times as many applications they would like to use. The best way is to use SSO, so, it will be possible to have a portal, where users could launch any application used in a company. There are many different ways how to give access to your application by using the SSO mechanism, and some of them are:
OAuth2
Kerberos
SAML
InterSystems already supports OAuth2 and can be quite easily deal with Kerberos. But I would like to discuss about using SAML (Security Assertion Markup Language).
This is the first article in a series discussing how to regain disk space from Caché databases at the operating system level. This introductory article discusses Caché database growth and gives an overview of various methods you can use to return unused disk space that is allocated to database files back to the file system. But before we talk about returning space to the file system, let’s first review how does it get allocated in the first place.
