Hi, Community!

Here are some news on Developer Community enhancements.

In March we fixed a lot of bugs and rearranged the notification system, so I hope you'll be happy with it now.

Enhanced content of the notification

With this new release in every email notification you'll see the reason, why did you get this particular notification and the option to unsubscribe of this types of notifications.

Some languages ​​have the concept of a garbage collector for automatic memory management. I'd like to know if something like this exists in InterSystems Caché in the context of routines, %CSP.REST, or %CSP.Page.

The question arises from the %Close() method of the %RegisteredObject class. This indicates that I need to manually clear the object from memory if it's no longer in use, or in the web context, if the request has completed. Is this correct? Or am I completely wrong?

Thank you!

Share volumes across pods and zones on EKS

Background

For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.

Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:

Current triage systems often rely on the experience of admitting physicians. This can lead to delays in care for some patients, especially when faced with inexperienced residents or non-critical symptoms. Additionally, it can result in unnecessary hospital admissions, straining resources and increasing healthcare costs.

Reviews on Open Exchange - #38

If one of your packages on OEX receives a review you get notified by OEX only of YOUR own package.
The rating reflects the experience of the reviewer with the status found at the time of review.
It is kind of a snapshot and might have changed meanwhile.
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.
Some were accepted and merged, and some were just ignored.
So if you made a major change and expect a changed review just let me know.

Hello community, I need to solve a complex but trivial issue.

Given:

Two tables "Comment" and "Post". Each one contains an "Author" field, which is essentially a user ID. In these tables, each user ID represents an author. The goal is to count all participants together and then group them by month, language, and other metrics.

The question is how to do this within the IRIS ecosystem. Is it even possible to take two tables, get distinct data from them and then combine into one cube?

Hi Community,

Watch this video to learn how to manage your HealthShare HealthConnect Cloud deployments using the InterSystems CloudServices Portal. Inspect the details of your deployment, create users and productions in Health Connect Cloud, and access the System Management Portal for a given deployment:

Hi,

in our system we usually display an information if someone locks data that another user tries to edit. Like: "Data locked by <user>/<program>"

We have a global that is set at userlogin with following information:

^BA020(0,3,$job) = "<user>;<program>"

We show that information by getting the jobnr/owner from the locktable ^$LOCK("<ref>","OWNER") and looking at ^BA020.

Understanding process jobTpe

I have a client running cache on an AIX platform. I put together a objectscript to allow for the viewing the processes running against the database using a select from SYS.Process. One of the values I want in the view of the processes information is Jobtype but I want to convert it from the numeric value to a string value. In the Intersystems documentation there is a reference to an include file $syPidTab.inc that should include macros that make this translation. I have not been able to track down this include file.

Let's say I have a persistent class Sales.
I need to create a report that shows the amount of sales for each branch.
By simply using the class Sales for the source of the cube, I can show what I want with one little exception - the branches that did not have any sales are not shown.
Is there a way around that that does not involve creating a whole new table just for this cube or using a Data connector (they have horrible documentation and I am unable to figure out how to use them properly)?

Hi:

I have noticed a problem in some new code I did on one of our productions. I think it is leading to 2 problems.

I have a file, lets call it 1111111111_2300.pdf.

We make the file UNIQUE to avoid an issue. This filename in the working directory gets a session ID Added to it before the .pdf. So lets say it was session ID 9 it would be 1111111111_2300#SID9.pdf in a working directory .

There are further operations to be done on this document before it is sent. For various errors an email is sent back to service users.

High Availability IAM

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

Hi Team, we are going to deliver a speech on a developer forum where most developers hv not used our tech before but using other database and integration technologies , Pls give us some key points on why they should adopt us and the benefits you can get, especially if you change your tech stack from others to IRIS. Thanks a lot!
