Hi Community!

While we're on a roll with new ideas for the Developer Community, we decided to also give the credit where the credit is due (meaning you, our dearest members), and share your creativity and imagination with others.

We're going to introduce a new rubric "InterSystems Memes"! 😜

The goal of this writing was to illustrate how to restore backup before the patch would be applied. The alert notes that:

The risk can be avoided by applying journals from the beginning of the journal file that was switched to at the start of the backup, rather than accepting the default of starting from the journal marker position.

Having non-patched Caché 2015.1.4, I ran sample database backup and restore just to get where I should answer "No". Collecting journal info from the backup log:

We have multiple implementations spanning many namespaces and edges. I would like to see if I could identify a single place, perhaps on HSREGISTRY or HSBUS, that I could capture certain events like searches (from all customers) and record transfers (with requester and provider).

The goal is to have a dashboard that would show simple stats such as searches by participant, records shared by participant and records consumed by participant. These are the 3 most important.

I appreciated the feedback on the other question of "how" but now I'm hoping to find the "Where".

Background:

This guideline provides an overview of how to design and implement a REST API interface for querying patient demographic data from an Electronic Patient Record (EPR) system using HealthConnect. The process involves sending a query request with the patient's identification number, retrieving the response from the EPR system, extracting the required patient demographic data from the HL7 message, and sending it as a JSON response to the supplier. The high-level process diagram is shown below (Screenshot 1).

Java External Language Gateway

If you like Java and have a thriving Java ecosystem at work into which you need to incorporate IRIS, it's not a problem. Java External Language Gateway will do it seamlessly, almost. This gateway serves as a bridge between Java and Object Script in IRIS. You can create objects of Java classes in IRIS and call their methods. You just need a jar file to do this.

Connection diagram: proxy object <-> Gateway object <-> TCP/IP <-> External server <-> target object

How to understand what's wrong with compilation if the compilator just hides errors?

40 errors, and what do I have to do with this so valuable information?

Tracking %RCOPY and %RI

Let's supposed somebody updates routines via %RCOPY or %RI, the really old-style hardcore way which still works. Does that leave any log traces in Journaling or system globals, as of when exactly did it happen or what was the IP address of the machine changes came from? I am aware only of the Date Modified changes as seen when opening the file.

A confusing experience

During my last migration to IRIS I met this Compatibility parameter

  • NullSubscripts true
0 - Throw error when referencing a null subscript.
1 - Null subscript references do not throw an error.

The consequences are shocking. This was allowed:

Let's say I start with a date range of '1-5-2019' to '5-25-2019' that occurs on one row. I'd like to ultimately have this show as 5 rows in Crystal Reports as shown below

Result

I'm currently working on a project to run our medical device integration through ensemble.

I've noticed a potential problem with the volume of messages . The feed generates around 474K messages daily( average of 1 message per minute per device from 300+ devices).

We currently keep all our other feeds message data for 90 days and purge automatically. From what I can see is that the purge functions in Ensemble are production wide and cannot set it at the Business Operation, Service or Router level.

Hello,

I was wondering if there is a way to maybe temporarily alter the [Private] tag dynamically or any other way to run a Unit test against class method, which has been labeled as [Private]?

I mean, I understand there is a workaround to create a non private class method inside this class, which will in turn call this private method and run a Unit test on the non private method, but I am looking for a way to do this without altering the original class.

Thank you,

Alex

ZW in other stack frames

Hello,

is it possible to ZW variables in stack frames above the current one? I am calling a custom logging method, and would like to log variables from the point of call.

Thanks
