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?

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.

Code Golf: Label Validation

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"

I am writing a Python tool to query our cache instances for various information. I have set up the connection without issue:

import intersys.pythonbind3 as pyb

conn = pyb.connection()
conn.connect_now(.....)

db = pyb.database(conn)
qry = pyb.query(db)
obj = pyb.object(db)

I wanted to make the call:

execRes = qry.prepare_class("SYS.Database",'FreeSpace')

But fetching fails because of data mismatches ( as I understand from other posts) and my testing bears out this type of failure.

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.

How to become a time lord - Time travel

Time travel is like visiting Paris. You can't just read the guide, you have to throw yourself into it. Eat the food, use the wrong verbs, get double the charges, and end up kissing complete strangers.

The Doctor

We are now going to travel through time, that is, we are going to see future and past dates and how to calculate them in different formats. The TARDIS doesn't wait, take the controls and hold on tight.

ECP system ID

Hi,

I'm looking through some journal entries in the hope of finding the root source of an issue.
I was wondering if and how you can map a "ECP system id" to a server.

Any hints would be welcome

Best regards

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.

Hi,

I was playing around with the python binding for caché (2018.1.4) and I ran into some problems.

When executing the class query "List" from SYS.Database the pythonbind interface throws an exception, that seems to be caused by a mismatch of the defined SQL datatypes for this query and what is actually returned (or the lack of type conversion in the pythonbind interface).

Is this a known issue ? Are there solutions/workarounds for this,
Or is this a bug ?

The details:

Hi There,

I am reaching out to the community to see if anyone has implemented SSO via SAML into TrakCare from Azure AD?

Also looking to see if anyone has come across automated role provisioning, I have seen this from an IRIS perspective but not directly into TrakCare.

Thanks in Advance

Cheers,

TC
