(I wasn't able to find this in the docs or the Community, so feel free to point me to a reference that I missed)

How can I determine the effective User and Group that will be used when an InterSystems IRIS process is doing file I/O on the file system for UNIX? Bonus points if you can tell me how to do it from within InterSystems IRIS as well as from the host OS.

Thanks!

I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?

Traditional Debugging in ObjectScript

Finding errors in your code or examining unexpected behavior is the main purpose of Debugging
I will try to refresh the traditional tools away from the helpers you have in Studio, VScode, Serenji, ....
to the basics which have been there before your preferred EDI used it in the background.

Globals documentation

I have a client with cache instance that is growing by 10-30G/day. In order to determine what is consuming space I ran "DO ^%GSIZE" to generate a report. From the report the bulk of the space consumption is from a couple of globals which appear to be built in globals not user defined. I would like to find documentation that details the function of these globals to help me understand how and why space is being consumed at such a rapid pace.

IntegratedML walkthrough

The InterSystems IRIS IntegratedML feature is used to get predictions and probabilities using the AutoML technique. The AutoML is a Machine Learning technology used to select the better Machine Learning algorithm/model to predict status, numbers and general results based in the past data (data used to train the AutoML model). You don't need a Data Scientist, because the AutoML it will test the most common Machine Learning algorithms and select the better algorithm to you, based in the data features analysed.

VSCode: Formatter not found

Hi,

I am using VSCode together with IRIS 2021.1.
When using Shift+Alt+F to reformat a class file, it pops up with the below message. When I select install formatter, it routes me to the extensions page, where it shows the extensions as being installed. Any advice will be appreciated.

This article is a follow-up to the previous one on how to migrate from popular databases (like PostgreSQL and MySQL) to IRIS.
We will use the same procedures utilized to migrate from PostgreSQL. However, you will see that it is even easier since the data types in MySQL are very similar to IRIS. That is why we will not need to create transformation rules in the columns.

Get the sample data to the migration process

In GitHub it is possible to download a docker-compose project to build and run 2 databases:

In this article I will explain the usage of %SQL_Diag.Result and %SQL_Diag.Message table along with all-new LOAD DATA functionality.

It is recommended to go through LOAD DATA documentation first.

After successful operation LOAD DATA insert one record in %SQL_Diag.Result table and details are inserted in %SQL_Diag.Message table


Below is the basic command when table is already created and source file does not contain header row. 

LOAD DATA FROM FILE 'C://TEMP/mydata.txt' 
INTO MyTable

The file name must include a .txt or .csv (comma-separated values) suffix and both source and target have the same sequence of data columns.

Loading from File Source: Header
