Function as a service (FaaS) is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Building an application following this model is one way of achieving a "serverless" architecture, and is typically used when building microservices applications.  

Wikipedia

FaaS is an extremely popular approach to running workloads in the cloud, allowing developers to focus on writing code.

This article will show you how to deploy InterSystems IRIS methods in a FaaS way.

The Complex Recordmapper specify a map for headers, body, and trailers, but it expects all three to have fixed Leading Data to identify the record type. But what if the Header and Trailer have Leading Data, but not the body records? I can't seem to find a way to do this.  For example:

HEADER|194|2012|Fall|20
12345|Adams|John|Michael|2|john.michael.adams@example.com|617-999-9999
12347|Jones|Robert|Alfred|1|bobby.jones@example.com|
TRAILER|8|100

Ideas?

Hi Community,

We'll look at moving InterSystems workload to the public cloud, then take a deep dive into the current architectures on the InterSystems cloud platform:

This is the third part of the series of articles on migrating from the main databases on the market to InterSystems IRIS.In this part, the procedures for migrating from DB2 will be detailed.As described in previous articles, there are currently a few options to do the migration.However, the two most popular options include the usage of DBeaver (https://openexchange.intersystems.com/package/DBeaver) or SQLGateway.

New month, new code golf!

You will receive a string with a label code with numbers and letters. Our challenge is to check if this code begins with 1, 2, or 3 and ends with A, B, C, S, or R. It should return true(1) if so or return false(0) otherwise. As usual shortest solution wins.

##Input "198739A79D9R"

##Output 1

##Note

• The string only contains numbers and upper-case letters. No other special characters.
• Use this code to check the solution length
• You also can use this test case here

I want to have a script that can run from the usual unix, linux, or aix command line. It has to be able to get into an irissession and use set statements to get data using sql. It seems like I'm in a catch-22. When I use the irissession SERVER command at the command line, I can't run a script. When I put the irissession SERVER command in a script, it won't run anything in the script after that.

My goal for this script is to get this information and put it into a file which I can then parse.

Hi Community,

Let's meet together at the online meetup with the winners of the InterSystems Python contest!

You'll have an opportunity to have a discussion with InterSystems Product Managers on the new IRIS 2021.2 Embedded Python functionality, Q&A on Python, etc. Our winners' demo included!  

Date & Time: Thursday, March 3 – 10:00 EDT

NOTE: we previously found an issue with the 2021.1.1.324.0  builds.   The 2021.1.1 maintenance releases have been removed from the WRC and have been  replaced with 2021.1.2.336.0 builds.  2021.1.2 containers will be available shortly.

Two new sets of maintenance releases are now available: 

• Caché  2018.1.6, Ensemble 2018.1.6, and HSAP 2018.1.6
• InterSystems IRIS 2020.1.2, IRIS for Health 2020.1.2, and HealthShare Health Connect 2020.1.2

Installation kits and containers can be downloaded from the WRC Software Distribution site. Container images for the Enterprise Editions of InterSystems IRIS and IRIS for Health and all corresponding components are available from the InterSystems Container Registry.

I entered the irissession SERVER command and got the prompt PROMPT>

Now I want to exit this and return to the generic aix prompt $

I try q, quit, e, exit... none of these work.

7) You need the right driver

If you want to execute the LOAD DATA sql command you have to choose the driver from 2021.2! If you select the wrong driver and use the LOAD DATA sql command you get something like

 Error: [SQLCODE: <-1>:<Invalid SQL statement>]
[Location: <Prepare>]
[%msg: < LITERAL ('%qpar') expected, : found^LOAD DATA FROM FILE :%qpar>]

I've forked the jdbc driver repo https://github.com/intersystems-community/iris-driver-distribution and added the driver from InterSystems IRIS Version 2021.2.0.617

You can download the intersystems-jdbc-3.3.0.jar from here:

Hey Developers,

It's time to announce the winners of the InterSystems Python contest! Are you ready?

A storm of applause goes to these developers and their applications:

Hello all,

I've seen that to install any python library we just need to call this:

C:\InterSystems\IRIS\bin>irispip install --target C:\InterSystems\IRIS\mgr\python geopy

Is there a way to install the libraries in a different directory and set up the system to load the python from that other directory?

Monitoring IRIS through SAM (sam:1.0.0.115)

While I've used to make it work in the past, I'm not able any more to fix the already faced issue : "State: Unreachable"

Despite all the ip-addresses attempts (or hostname = host.docker.internal)  and while "/api/monitor/metrics" is running well...

Could someone provide good practices to make it work cleanly ?

Hello,

I'm using the InterSystems Iris odbc driver (DriverODBCVer=02.10) to get data from Iris table but it is slow.

Is there any options to improve performance ? Increase the packet size ?

Change to do in odbcinst.ini / odbc.ini to make it quicker ?

Thanks

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic.  

It will  undoubtedly my fault that I don't understand or misread the concepts of "database" vs Globals, envisioning files as such while one set of functional Globals in one file (?!) could comprise of a database, hence it is one file after all, that file (block structure) not able to be larger than 17GB

Hi Community,

I have created CSP page should show my Queue status.

Now I need to refresh this page every 5 min.(same like live score website) to reload new queue status.

Any tag in CSP will do this auto refresh?

I'm building a .Net Core Gateway container. Here's the issue.

As a final step I'm building a .Net Core 2.1 library. It has a runnable dependency - .Net Gateway, which I need to start first.

However dotnet publish generates .runtimeconfig.json and .deps.json only for my library and not for my dependency (.Net Gateway).

Is there a way to force dotnet to generate .runtimeconfig.json and .deps.json for a dependency?

I have tried:

  <PropertyGroup>
    <GenerateRuntimeConfigurationFiles>true</GenerateRuntimeConfigurationFiles>
    <GenerateDependencyFile>true</GenerateDependencyFile>

With the latest improvements in support for Python in IRIS, and continued work on Python DB-API support by InterSystems. I've implemented IRIS support to the Django project where is Python DB-API is used to work with some other databases.

Let's try a simple application on Django, which stores its data in IRIS.

We are happy to share interesting information with you, as well as tell you why Python is good, where it is used.

Among the most used libraries are NumPy and Pandas. NumPy (Numerical Python) is used to sort large datasets. It simplifies mathematical operations and their vectorization on arrays. Pandas offers two data structures: Series (a list of elements) and Data Frames (a table with multiple columns). This library converts data into a Data Frame, allowing you to remove and add new columns, as well as perform various operations.

Python offers countless tools for data analysis projects and can

Hi Community,

for our forms validation we use XData to describe fields on server side.

These XData are in JSON like this

XData FormValidator [ MimeType = application/json ]
{
 {
  "username": {
   "required": true 
  },
  "email": {
   "datatype": "email"
  }
 }
}

When I try to use %JSON.Adaptor in same classes, IRIS throw an error at compile time

ERROR #6301: SAX XML Parser Error: invalid document structure while processing Anonymous Stream at line 1 offset 23

In my article I described the work using iris.gref .
As the official documetation is rather slim on the subject it was necessary to dig into it.
Using the power of Python I was able to detect what I needed but was hidden.
I decided to share this with you. pydoc did the magic. 

Hey there,

I posted a reply to the recent video https://community.intersystems.com/post/new-video-building-data-driven-web-apps#comment-132511
with a slew of questions.  Wondering if someone can take a look a address my questions on that post or on this new thread.

I find many InterSystems learning to be challenging to follow, but I"m not sure if it's because my work computer is so locked down that I don't have all the right tools and permissions I need to do what the tutorial asks, or if I'm not understanding the basics of Cache/IRIS, or both!
