You can set the maximum size of the IRISTemp database at IRIS startup by setting a configuration parameter called MaxIRISTempSizeAtStart.
After setting, the system will truncate IRISTemp to the set value (MB) at the next IRIS startup. If the current size is less than the specified MaxIRISTempSizeAtStart, no truncation will occur. Also, if 0 is specified, truncation will not be performed, so the size will start without changing. (Default) Settings are made from the menu below.
(Possibly?) little-known fact: It's possible to use $ListBuild on the left hand side of the equals sign in a set command to extract multiple list values at once:
set $ListBuild(several,individual,variables) = list
We are back to %SYS once again! Since we covered managing users and resources in the last two articles, we can finally move on to roles. As you may have guessed, there are a lot of methods of managing them that you have already seen in our previous writings.
InterSystems ObjectScript is perhaps the best language on the planet to deal with globals - and it is an interpretable language.
Yes, it has a compiler. But even the compiler can compile some lines in ObjectScript which will then fire as bugs during the runtime.
There are some technics on how to avoid that such as unit testing, coding guidelines and your coding experience, of course ;)
Here I want to present to you the yet another approach to how you can reduce the number of errors in your ObjectScript runtime and enforce coding guidelines - it's an ObjectScript Quality tool developed by Lite Solutions, InterSystems solution partner.
Hello everyone, this is with great pleasure that I announce the V2 of my application 'Contest-FHIR'.
In this new version, I used new tools and techniques I discovered at the EUROPEAN HEALTHCARE HACKATHON in which I was invited by InterSystems as a guest and as a mentor to display the multiple projects I did in my intership back in April 2022.
Today I present to you the V2 of my application, it can now transform CSV to FHIR to SQL to JUPYTER notebook.
In part 1 and part 2 of this series we set up two user types, simpleuser and poweruser. In this part of the tutorial we create one last user type having privileges typically needed by an administrator/developer in analytics.
Brainstorming the project we would build to showcase in the current female health themed InterSystems FHIR Contest, our girl band decided that we need to do something practical for the ordinary user and to solve some burning issues of the modern life. This discussion led to the idea of creating a project that will help women not to forget their health in daily grind - FemTech Reminder.
While starting the development with IRIS we have a distribution kit or in case of Docker we are pulling the docker image and then often we need to initialize it and setup the development environment. We might need to create databases, namespaces, turn on/off some services, create resources. We often need to import code and data into IRIS instance and run some custom code to init the solution.
And there plenty of templates on Open Exchange where we suggest how to init REST, Interoperability, Analytics, Fullstack and many other templates with ObjectScript. What if we want to use only Python to setup the development environment for Embedded Python project with IRIS?
So, the recent release of Embedded Python template is the pure python boilerplate that could be a starting point for developers that build python projects with no need to use and learn ObjectScript. This article expresses how this template could be used to initialize IRIS. Here we go!
t's also an example for a customized command extension (ZZJSN) in Caché & IRIS
This is the Caché version for fast JSON formatting but it also works in IRIS. Requires package ZPretty To allow parallel existence in IRIS this is named ZZJSN
I'd like to share with you some storage features that also exist in Caché but are almost unknown and mostly not used. They are of course available in IRIS and gain importance with large and distributed storage architectures.
The DeepSee Shell best Practices Series - Execute an MDX query in the DeepSee Shell with/without results cache
This cache is different from cache reset. Cache reset clears everything in the namespace but “cache off” only clears the cache in ^DeepSee.Cache.Results and ^DeepSee.Cache.Axis global node for the corresponding cube. The difference is quite smaller in the case as below, but in some cases it can be a big difference.
In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.
【Usage class】
Class User.test Extends %Persistent
{
Property pics As %GlobalBinaryStream;
}
We heard from a customer who wanted to display a version number as a read-only production setting. During the build on the build server, this version number is added to the Production class. This works fine, and the Version is displayed in the Portal, but the customer wanted to write protect it, so the enduser can’t change it. The customer had defined the setting like this:
Property Version As %String;
Parameter SETTINGS = "Version:Info";
We advised the customer to define SETTINGS like this instead:
You can programmatically retrieve routine dates and sizes using the RoutineList query of the %Library.Routine (or just %Routine) class.
The RoutineList query has an argument, and the routine name to be searched can be specified by prefix match or middle match. (For wildcards, specify * or ?)
In the example below, *.MAC is specified as an argument.
I've released a comprehensive, free online training course on the new EWD 3 suite of products that allow the integration of Cache with the burgeoning Node.js world, and allow you to create and run browser-based and mobile applications with all the very latest development technologies from the JavaScript world.
When you have been using cubes for business intelligence in a namespace for some time, you may find that there are many cubes in the namespace, only some of which are actively being used. However, it can be difficult to tell which cubes users are or are not querying, and maintaining unused cubes can be costly both in terms of storage and of computation to keep them up to date. This article provides some suggestions and examples for monitoring which cubes are in active use, and for removing cubes that you determine are no longer necessary.
This is my introduction to a series of posts explaining how to create an end-to-end Machine Learning system.
Starting with one problem
Our IRIS Development Community has several posts without tags or wrong tagged. As the posts keep growing the organization
of each tag and the experience of any community member browsing the subjects tends to decrease.
First solutions in mind
We can think some usual solutions for this scenario, like:
Here we are again with an article related to the Mirror!
In the previous article we saw how we could configure a Mirror between two IRIS instances, one acting as an active node and the other as a passive one. This mirroring system works on the transfer of a journal file that keeps the instance that works as a passive node continuously updated, but what happens if due to some communication failure or permissions of the journal file it is not transferred correctly?
