There is not just one class in this package: rcc.gstream.cls but also rcc.gstreamT.cls
While rcc.gstream works with direct access to the stream globals, the *T version uses a Process Private Global (PPG) as Temporary storage. using SELECT * FROM RCC.gstreamT WHERE RCC.useT('^jpgS')=1 and similar.
In general Global Streams are data objects embedded in Classes / Tables. Using and viewing them with SQL is normally a part of the access to the containing tables.
SO WHAT?
During debugging or searching for strange or unexpected behavior there could be the need to get closer to the stored stream. No big problem with direct access to Globals with SMP or Terminal. But with SQL you are lost. So my tool provides dynamic access to Global Streams wherever you may need this Special thanks to @Oliver Wilms for the inspiration for this tool.
For me, one of the most painful things about ObjectScript is ##class(Class).Method() typing to call a class method in code or in a terminal. I even submitted an idea to simplify it in ObjectScript.
But! There is a new feature in VSCode ObjectScript that was just introduced to the plugin - Copy Invocation!
Predictable storage IO performance with low latency is vital to provide scalability and reliability for your applications. This set of benchmarks is to inform users of IRIS considering deploying applications in AWS about EBS gp3 volume performance.
Summary
An LVM stripe can increase IOPS and throughput beyond single EBS volume performance limits.
When creating a PRA (Privileged Routine Application; which by the way is not relevant just for Routines but also for Classes/Methods), it is important to make sure you include a new $ROLES, before calling
The topic of for/while loop performance in Caché ObjectScript came up in discussion recently, and I'd like to share some thoughts/best practices with the rest of the community. While this is a basic topic in itself, it's easy to overlook the performance implications of otherwise-reasonable approaches.
A small reflection/question for today... it's true that new IRIS for Health (I4H) releases are more and more powerful each time regarding FHIR capabilities. Nowadays it allows us to consume FHIR resources with extrem easiness, we can connect with end-points in external FHIR servers very easily and make I4H act as passthrough or consume their resources... or, even more, we can define, configure and run a FHIR repository in, literally, less than 5 minutes.
It's not an easy task to be a master of dates and times, it is always a problem and sometimes confusing in any programming language, we are going to clarify and put a few tips to make this task as simple as possible.

I have recently come across a problem saving TrakCare reports as PDF files while using the MS Edge browser on a Windows 10 PC. Whenever a user selected the Save to PDF option the window Tab would crash and reset. The event was trapped and viewable in the Windows Events Viewer and showed a Fault in the AcroPDFImpl64.dll.
If you’re on the fence about learning InterSystems ObjectScript, we’re making the decision a whole lot easier.
We just updated the “Getting Started with InterSystems ObjectScript” learning path with 3 new 5-minute videos — and a capstone exercise to help you pull together everything you’ll learn.

Caché 2015.2 announced support for TLS v1.1 and v1.2. In this version, the SSL/TLS configuration page provides checkboxes for TLS v1.1 and v1.2, which allows the versions to be configured individually. This allows sites to, for example, require TLS v1.2 only.
Additionally, some earlier versions of Caché provide undocumented support for TLS v1.1 and v1.2, specifically Caché 2014.1.3 and above and 2015.1, on Windows, Linux and Unix.
There's an easy new way to add certificate authority (CA) certificates to your SSL/TLS configurations on InterSystems IRIS 2019.1 (and 2018.1.2) on Windows and Mac. You can ask IRIS to use the operating system's certificate store by entering:
%OSCertificateStore
in the field for "File containing Trusted Certificate Authority X.509 certificate(s)". Here's an image of how to do this in the portal:
The InterSystems Learning Website has many important iterative courses. So if you want to learn about InterSystems and start to work with InterSystems this is the path:
I'm trying to take an unformatted social security number and insert the dashes into it. I'm getting a value in PID-19 like this: "123456789" and would like to use a data transformation to set the value in PID-19 to "123-45-6789".
We are upgrading from Cache to IRIS this weekend and I was curious what version of IRIS I need to download. Once our system is live on IRIS, I will no longer be able to use Ensemble. If anyone knows the version of IRIS and could pass that along to me, it would be much appreciated.
In this post I show strategies for backing up Caché using External Backup with examples of integrating with snapshot based solutions. The majority of solutions I see today are deployed on Linux on VMware so a lot of the post shows how solutions integrate VMware snapshot technology as examples.
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.

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.
The last days I've work with the great new feature: LOAD DATA With this post I would like to share my first experiences with you. The following points do not contain any order or other evaluation. These are only things that I noticed when using the LOAD DATA command. It should also be noted that these points are based on the IRIS Version 2021.2.0.617 which is a preview release. So it may be that my observations do not apply to newer IRIS versions.
When designing a hierarchy in DeepSee, a child member must have only one parent member. In the case where a child corresponds to two parents, the results can become unreliable. In the case where two similar members exist, their keys must be changed so that they are unique. We will take a look at two examples to see when this happens and how to prevent it.
