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 :

1. Create an iris.service file in /etc/systemd/system/iris.service containing the following information

I found myself in the not-so-comfortable situation of working with a Linux system on which someone had accidentally disabled user access to the Linux shell. HealthConnect was running, servicing hundreds of interfaces. To resolve the access issue, though, we needed to bring the host down for the application of a fix.

Without the shell, the iris command is not available to control the instance, so we were faced with the potential of shutting down the server ungracefully. We wanted to avoid that if possible ...

Monitoring your IRIS deployment is crucial. With the deprecation of System Alert and Monitoring (SAM), a modern, scalable solution is necessary for real-time insights, early issue detection, and operational efficiency. This guide covers setting up Prometheus and Grafana in Kubernetes to monitor InterSystems IRIS effectively.

This guide assumes you already have an IRIS cluster deployed using the InterSystems Kubernetes Operator (IKO), which simplifies deployment, integration and mangement.

InterSystems FAQ rubric

Temporary globals stored in the IRISTEMP/CACHETEMP databases are used when a process does not need to store data indefinitely, but requires the powerful performance of globals. The IRISTEMP/CACHETEMP databases are not journaled, so using temporary globals does not create journal files.

The system uses the IRISTEMP/CACHETEMP databases for temporary storage and are available to users for the same.

So, you checked your server and saw that IRISTEMP is growing too much. There's no need to panic. Let’s investigate the issue before your storage runs out.

Step 1: Confirm the IRISTEMP Growth Issue

Before assuming IRISTEMP is the problem, let’s check its actual size.

Check the Free Space

Run the following command in the IRIS terminal:

%SYS>do ^%FREECNT

When prompted, enter:

Currently we are exploring how we can allocate additional disk space to our current environment as we have seen a significant increase in growth of our Database files. Currently we have 3 namespaces, all with 1 IRIS.dat each that contains both the Global and Routines.

Since we have started down the route of everything within a single IRIS.dat file for each namespace, is it logical as we see growth to be able to split the current IRIS.dat for each namespace into a separate IRIS.dat for global and a IRIS.dat with for routines for each namespace in a Mirror environment?

Has anyone noticed weird behavior when upgrading to HealthShare Health Connect 2024.1?

Wednesday I upgraded our TEST environment from IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2022.1.4 (Build 812_0_22913U) [HealthConnect:3.5.0-1.m1] [HealthConnect:3.5.0-1.m1] to IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2024.1 (Build 267_2U) [HealthConnect:3.5.0-1.m1].

Some of our Business Processes have been throwing...

Hi,

I recently had a company-enforced OS upgrade, and ever since going from mac OS 14.x to 15.x, I am currently having issues with SSL in IRIS.

An ARM (M3 pro) machine running OS 15.2, with the latest Docker Desktop (at the time of writing, 4.37.0). The Docker container runs IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2022.1.2 (Build 574_0_22161U). This container has not changed.

LDAP Authentication Question

I am trying to track down a problem we saw this morning with our TEST environment. We had a momentary issue where InterSystems HealthShare Health Connect could not connect correctly to LDAP. When we tried to login and could not connect to LDAP, the system would Delete our users.

the Test LDAP function would return a "Can't contact LDAP server". I went through the Certificates, made sure they had the correct permissions and were not expired.

I have a few routines in ^rINDEX that are missing in ^ROUTINE. At least some of those routines lack a timestamp, probably Date and Time Modified in ^rINDEX. It causes D %RO crash when such a routine is referenced by a routine range, since "" is an illegal $ZDTH value.

Healthy entry (note the timestamp): ^rINDEX("ABC,"INT") = $lb("2021-06-15 15:08:38.846885",) ;The second argument is sometimes present and sometimes not, likely the routine size.

Unhealthy entry (note an empty timestamp): ^rINDEX("DEF,"INT") = $lb("",21)

I am developing locally on my IRIS instance using VSCode and client-side editing approach. How can I automatically export a single .cls file/a whole package to a remote TEST/PREPROD server using a script or command line and recompile the unit remotely? Are there any more simple and straightforward ways than CI/CD explained in the series of articles by Eduard?

Hello,

I was just trying to get to the bottom of a TLS config - we have an interface with a TLS config that has had 'Server certificate verification' set to 'On', however the cert file specified either did not exist or contained a cert that was expired.

Does anyone know what the behavior is for this typically? I would expect this to not allow traffic on the interface, however this has been working fine for a few years now with an invalid cert specified for 'Server certificate verification' and set to 'On'.

Hi,

In a customer project we started enforcing the "Inactivity Limit" as defined in System-Wide Security Parameters. The customer would expect accounts to become Disabled after they have been inactive for the specified amount of days. However, that doesn't happen; it seems the Inactivity Limit is only established after logging in.

Furthermore, the account inactivity only starts being applied after the first login. Can you confirm that?

Lastly, for accounts that have been manually Disabled, and have an expired password, we see the following weird behavior:

Hi beloved members of the Community!

It is very common in the daily life of IRIS or Health Connect users that it is necessary to install new instances or update the ones they already have and in many cases it is not these same users who carry out the installation, but rather systems personnel who often do not take into account the particularities of the assignment of permissions necessary for the installation.

Once upon a time in Ensemble Management Portal the pool size of each component (Business Host) within the production was displayed in the Production Configuration page.

This information was very useful, especially when a production have tens or hundreds of components.

I have two instances of IRIS, one is Production and another one is Staging (both managed by Docker) and I want to set up a full daily recover of the Staging server from a full backup of the Production server. I know how to do this manually using the DBREST utility, as well as how to make a copy of the database by making a full copy of the durable directory (however this option requires a full stop of the Production-database). What is the best way to automatically restore all databases from a full backup using scripting?

I have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?
