Caché process failures on RHEL V7.2

Caché process failures on RHEL V7.2

InterSystems WRC has investigated several issues of process failure that can be attributed to a recent change in Red Hat Linux.

A new feature implemented in RHEL V7.2 (systemd-219-19.el7.x86_64) can cause O.S. IPC (Inter-process communication) semaphores to be deallocated when a non-system RHEL user logs out (system users, i.e. with a UID number < 1000, are excluded)

This is a continuation of my story about the development of my project isc-tar started in the first part.

Just having tests is not enough, it does not mean that you will run tests after all changes. Running tests should be automated, and when you cover all your functionality with tests, everything should work well after any change in any place. And Continuous Integration (CI) helps to keep the code and deployment procedure with as fewer bugs as possible and automates the routine procedures, like publishing releases.

I use GitHub to store the source code. And some time ago GitHub started to work on its own CI/CD platform and named it GitHub Actions. It is not widely available, yet. You have to be signed as a beta tester for this feature, as I did. GitHub Actions uses quite a different way how to deal with a build workflow. What is important that Github Actions allows to use Docker, and it’s quite easy to customize available actions. And interesting that GitHub Actions is really much bigger than any classic CI like we have in Travis, Circle or Gitlab CI and so on. You can find more in the official documentation.

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()
25

Hello fellows, I need you wisdom.

In my organization we code in ObjectScript and .int everyday. When I joined nobody knew barely nothing about classes and their use was almost only for storage definition purpose. During my self-learning in caché I discovered the object oriented programming and class developing was possible in caché and started to code in .cls . Being something self-taught, I may have some basic doubts I'd have missed in my documentation readings.

Hello,

I am working in a csp application where the user can configure a TCPS Service in a guide like manor.

So I want to be able to present a html <select> element, the values / text I want to present in this control should be the ID field from Security.SSLConfigs in the %SYS namespace.

How would I go about doing this? Can this be done?

Best regards,

Magnus

I'm pleased to announce a major release of the InterSystems Server Manager extension. It has gained a UI!

Read more at Open Exchange.

Right now version 2.0 is like an aircraft at the start of the runway (remember those days before COVID-19?), waiting for the control tower to give final clearance. Will you be an early adopter, downloading the VSIX from GitHub, installing it into your VS Code, and posting back here to confirm that we haven't left anything critical behind at the gate? Then I'll push the throttles forward, publish to Marketplace, and we'll all be on our way.

Server Manager 2.0 is my entry for the current contest. If you like it maybe you'll vote for me it.

I am looking for a solution with Ensemble to talk to a old NTLM based SOAP Service. Does anyone has done this before?

We have the webservice calls working via SOAPUI but we are looking how we can make it work with Ensemble.

Is there a ready to use Outbound Adapter for NTLM ?

Thx.

Introduction

As AI-driven automation becomes an essential part of modern information systems, integrating AI capabilities into existing platforms should be seamless and efficient. The IRIS Agent project showcases how generative AI can work effortlessly with InterSystems IRIS, leveraging its powerful interoperability framework—without the need to learn Python or build separate AI workflows from scratch.

Parquet files and InterSystems IRIS

In the world of Big Data, selecting the right file format is crucial for efficient data storage, processing, and analysis. With the massive amount of data generated every day, choosing the appropriate format can greatly impact the speed, cost, and accuracy of data processing tasks. There are several file formats available, each with its own set of advantages and disadvantages, making the decision of which one to use complex. Some of the popular Big Data file formats include CSV, JSON, Avro, ORC, and Parquet.

Hi-

I have Atelier client installed on a Mac and every now and then it just stops working. Currently I am getting this error when I try to synchronize my workspace with the server.

Synchronization failed: [server is broken] java.lang.ClassNotFoundException: Provider org.glassfish.jersey.internal.RuntimeDelegateImpl could not be instantiated: java.lang.IllegalStateException: No generator was provided and there is no default generator registered

Is anyone else experiencing similar problems and if so, what is the work around?

Those of you who are following the FullStack competition here in the Developer Community will know that I submitted an entry named qewd-conduit. I wanted to summarise why I think it's something worth you taking a bit of time to check out.

qewd-conduit uses the Node.js-based QEWD framework alongside IRIS to implement the back-end REST APIs for something known as the RealWorld Conduit application:

Hello,

We would like help to know why our web service which gets Patient's ID number, does not accept messages?

We observe its Event Log, and it contains the following pattern:

We detail each log to give info to discover what's happening:

First there is a new connection:

Then it suddenly disconnects

After that it looks like the service restarts:

Missing Mirrored Database

Hi guys

I've added a new mirrored failover member to an existing one.

They are both Arbiter controlled.

When I do Add database to mirror on the primary I'm always getting an error. Missing Mirrored database.

I followed everything in the documentation and always get the same error.

I've copied the CACHE.dat file after umounting the database on both servers. then mounted them.

Could you help me out?

Kind Regards

So we are still fairly new to the ensemble app and getting set up. I have 3 seperate batch record file services that pull in files and send to 3 seperate processes. there is no real rules other than an when condition=1 use this said DTL and send to operation. all 3 of these routers use different DTL's as they are seperate files but all go to the same operation. for some reason i am seeing the files sit in the Process and say Delivered. 2 of the three process after up to 10-15 mins of sitting and the third gets an error i am very unfamiliar with, so this post is two-fold.
